threatened plants and wildlife; (xii) Pasture Science; (xiii) Ecological and organic agriculture.
Scientific research at LEA up to now has yielded more than 350 scientific publications in
peer-reviewed international journals, books and proceedings of scientific conferences.
Moreover, LEA has executed and been involved in several projects (e.g DADOBAT-UE;
SUN-UE; BIOTA-West; LOEWE; UNDESERT-EU; Edulink-European Union; Global
Climate Change Alliance) on sustainable management of natural resources or/and tree
domestication in Africa.
Up to date, the major achievements of LEA are the following: (i) climate change,
vulnerability assessment and natural/climatic risk management in the coastal area of Benin,
(ii) conservation and management of more than 10 forest genetic resources in Benin (e.g:
Adansonia digitata; Blighia sapida; Caesalpinia bonduc ; Irvingia gabonensis ; Pentadesma
butyracea ; Sclerocarya birrea; Tamarindus indica; Borassus aethiopum; Raphia soudanica,
Dialium guineense, etc.) ; (iii) management of more than 10 traditional agroforestry systems
involving medicinal plants in Northern Benin (e.g Community gardens of Papatia, Monts
Kouffé, Dangbo, Porga, etc.) ; (iv) ecological restoration of more than 5 degraded areas (E.g.
Lama forest reserve and Swampy forest of Lokoli in Southern Benin ; Dry dense forest of
Bassila and Wari Maro in Northern Benin; etc.) ; (v) management of at least 5 protected areas
in Benin (Biosphere Reserves of Pendjari and W in Northern Benin ; three forests reserves,
Goungoun and Sota forests in Northern Benin ; Lama Forest reserve in Southern Benin ; etc.)
; (vi) Red list of threatened plants and wildlife in Benin (IUCN Red Book of Benin) ; (vii)
remote sensing and mapping of vegetation (Swampy Forest of Lokoli, Dense Forest of Lama;
Biosphere Reserves of Pendjari and W; etc.); (vii) atlas of biodiversity of Benin.
LEA works closely with many international and natonal partners (research institutions, NGOs,
local communities and decision makers). LEA networks and working groups include:
About 5 full Professors and 20 Associate Professors from many Departments (Regional
Planning, Geography, Chemistry, Soil Science, Botany, Socio-economics, etc.) at the
University of Abomey-Calavi ;
International Scientific Groups such as AETFAT, IUCN (WCPA; SSC ; CWRSG), etc.;

This report is the seventh edition following six consecutive previous reports since 2007. It is
intended for several audiences of researchers in Benin and abroad, partners, developers,
donators and other professionals interested in the fields of applied ecology. It summarizes the
research activities which were performed at the laboratory in 2014 and is organized into nine
major sections. Section 1 relies on the methodology used to gather information included in the
report and shows how various indices have been calculated. Section 2 focuses on the types of
research (individual, national teams, regional teams and international teams), types of
publications (thesis, peer review articles, proceedings, technical reports, and newsletter),
trends of publications for the last fourteen years (1998 – 2014) and the analysis of language of
publications according to the types of publications at the laboratory. Section 3 provides a
summary of conferences and seminars organized by the LEA in 2014 and those attended by
researchers from LEA. Section 4 describes the research projects and research grants obtained
at the laboratory in 2014 whereas section 5 shows details about active human resources at
LEA as well as visitors who were in the laboratory in the framework of bilateral
collaboration. Section 6 discusses the research activities performed at the laboratory in 2014
while section 7 shows the used references. The appendixes are presented in the section 8,
showing full details on references of the different types of publications, research projects and
grants as well as on conferences and visiting research in the laboratory. Finally, abstracts of
publications in 2014 in peer review journals have been presented in the section 9 to allow
easy searching and understanding of the full length papers.

1. Data collection
The methodology used for this report was mainly based on the research activities performed
by researchers and students from the laboratory in 2014.
Firstly, information related to dissertations (PhD and masters’ students), scientific articles
(published, in press or under review) in peer-review journals and those published through
proceedings, books of abstracts and technical reports were used. For each category of
publication, the indices of specialization related to the scientific fields in which the works
have been performed were assessed. Also, as far as the published papers in peer-review
journals are concerned, two groups of papers were established: articles with Impact Factor
and those without Impact Factor (Web of Science of Thomson). Only the publications of
which address of authors and/or co-authors refer to LEA were considered. Furthermore,
collaborations and co-publications with scientists from developed countries and African
countries have been detailed throughout the report.
The types of research were expressed respectively as the ratio between the number of
publications produced individually or by co-publication with national, regional or
international teams and the total number of publications in the laboratory.
Trends of publications from 1998 to 2014 were assessed both for proceedings and published
articles in peer review journals (with Impact Factor or not). The ratio French/English was
computed for various types of publications including the ones in press.
For data processing, the following indices were calculated:
- Specialization Index of publications which is the ratio between the number of
publications in a given field or discipline and the total number of publications when
considering all disciplines;
- Impact Factor (IF) Index of Publications for a given field of publication which is the
ratio between the number of publications having an Impact Factor and the total
number of publications in peer review journals related to the considered field of
publication;
- Weighted Impact Factor Index of a given field of publication which is the product of
the Impact Factor Index of Publications and the arithmetic sum of impact factor
indices as described in the web of science of Thomson;
- Index of co-publication at country vs. continental level which is the ratio between the
number of co-publications at country vs. international level and the total number of
co-publications in the laboratory.
- Estimated cost perpublication which is the ratio between the estimated budget of LEA
at a given year and the total publication at this year
- Estimated cost per impact factor unit is the ratio between the estimated budget of LEA
at a given year and the arithmetic sum of impact factor indices
- Contribution of LEA to scientific publication at Faculty of Agronomic Sciences (FSA)
and University of Abomey-Calavi (UAC) which is the ratio beween the total
publication at LEA and the total publication at FSA or UAC.
Information related to the conferences and seminars (organized by the laboratory and the ones
to which the researchers from the laboratory have participated), research projects, grants,
prices and awards are presented in the report.
To allow the assessment of the full references used to compute this report, a so called session
“appendixes” has been inserted at the end of the report as well as the abstracts of the
published papers in the peer review journals.

2. Types of research and publications at LEA in the year 2014
2.1 Type of research at LEA
In the year 2014, the published articles were mostly produced through national teams (34
papers out of 51). About 33.33% of the original research papers from LEA were published in
international journals with Impact Factor. In most cases, these papers involved national and
international partners (Figure 1).

Legend: IF = Impact Factor; WIF = Without Impact Factor
2.2 Type of publications at LEA in 2014
2.2.1 Theses at LEA
The number of enrolled students in Master degrees in 2014 (24 students) increased since
2007. This is due to the system LMD started at the University of Abomey-Calavi since 2007
which allow more students to attend the course. The first degree in the system LMD is The
BSc in which 31 students were enrolled in 2014 at LEA. The number of enrolled students in
PhD degrees at LEA has increased globally from 2007 to 2014 (Figure 2). A total of eight
PhD students have defended their PhD in 2014 at LEA. The professors of LEA (full and
associate) are actively involved in promotion and supervision of PhD and MSc theses (figure
3). One professor supervised at least 3 ongoing PhD and 5 MSc theses in 2014. The same
trend is also observed between associate and assistant professors for the supervision of BSc
thesis in 2014 (6 students per associate or assistant professor).

2.2.1.1 Ongoing PhD theses at LEA in 2014
In 2014, six main fields of research were covered by the PhD students at LEA (Figure 4).
Forest and Plant Ecology management, Wildlife ecology/protected aeras management and
Horticulture are respectively the most and less represented (Figure 4). Figure 5 highlights that
LEA research teams have mainly focused their activities in the fields of: Forest and Plant
ecology, Wildlife management, Agroforestry and NTFPs (Figure 5). This is congruent with
the laboratory’s main research projects.

2.2.2 Scientific productions at LEA in 2014
In 2014, 94 scientific publications were produced by teams of LEA in peer-reviewed journals:
51 published; 15 in press and 28 under review. Moreover, 29 abstracts were published in the
books of abstracts and 10 technical report elaborated.
2.2.2.1 Publications in peer review journals
(i) Number, categories and impact factor indexes of publications
The published articles in 2014 are mostly in the peer review journals without IF (67 %)
compared to the number of published papers in reviews with Impact Factor (33 %), (Figure
7). The number of articles in press and under review in the journals with Impact Factor in
2014 is higher than the ones without Impact Factor (32 vs. 11). The same trend was observed
in previous years. As such, we can assume that researchers of LEA are improving their
scientific capacities in publishing their papers in peer review journals with IF. Full references
(authors, journals, etc.) of those publications are shown in appendices 6, 7, 8, 9, 10 and 11.

Wildlife and Grassland (7%), Forest and Plant ecology (7 %).
Figure 9: Articles in press according to the fields of research in 2014
c) Articles under review The articles under review also cover the same fields of disciplines as the ones published and
in press. Fields having more articles under review were Wildlife and Grassland (34 %),
Agriculture and Agroforestry (29 %), Forest and Plant ecology (14 %), Ethnobiology (11 %),
and Risk assessment and Climate change (3 %). These fields were also found to contribute
more in articles published and in press confirming these areas as the more scientifically
productive within LEA.

(iii) Weighted Impact Factor Index of publications
Publications which have highly contributed to gain the Impact Factor of the laboratory in
2014 were related to Wildlife/grassland and Risk assessement/Climate change followed by
publications in Agriculture/Agroforestry, Forest/Plant ecology, Plant Biodiversity and
Ethnobiology (table 1). Therefore, these fields of publication are the ones in which the
recorded scientific publications in LEA had the highest Impact Factor in 2014.

2.2.2.2 Trends of publications in peer review journals and proceedings from 1998 to
2014
Publications in peer review journals have globally increased from 1998 to 2014 with the
highest peak in 2011 and 2013. Publishing in peer review journals with Impact Factor has
started in the laboratory in 1994 with 1 to 3 publications per year till 2005. For a given year,
the publications in peer review journals with Impact Factor were generally lower compared to
the ones in peer review journals without Impact Factor (Figures 13a).
Wildlife and Grassland, Ethnobiology, Forest and Plant ecology, Agriculture and
Agroforestry are the research fields in which the most publications are obtained since 2009 at
LEA (Figure 13b). This confirms these areas as the main research’s field of LEA.

2.2.2.3 Trends of research projects, research grants and publications in peer review journals
from 2009 to 2014
The research projects and small grants have increased at LEA since 2009 (figure 15). The higest
number of research projects and small grants is observed in 2014 (30). The same trend is also observed
with publications in peer review journals which globally increase since 2009. Thus while the
number of project increase, the number of publication also increase. Moreover, this trend is more

observed with the number of publication in impact factor journal which vary from 13 with 8 research
projets and small grants to 17-23 with 18-30 projets and small grants. With more research projects
and small grants, researchers at LEA publish more publication in peer review journal particularly in
impact factor journal.
The budget per year at LEA from 2009 to 2014 vary from 125 000 Euro to 185 000 Euro. While the
buget increase, the cost per publication decrease (table 2). In addition the total impact factor increase
with lower cost of publication per impact factor unit. This is due to the increasing number of grantees
PhD and MSc students involved in the research projects and small grants who have more time of
research and publishing. Thus with more funds, more publication are obtained with lower cost.

3. Conferences and seminars from 2009 to 2014
The participation of researchers at LEA to conference and seminar has increased from 2009 to
2014 (figure 18) with the highest peak in 2013. The researchers at LEA have participated
more to conferences and seminars in Africa than the others continents. In 2014, researchers at
LEA have participated to 40 conferences. About 67 % of these conferences were held in
Africa, 27 % in Europe, 3 % in Asia, and 3 % in USA (Figure 17). Details related to these
conferences/workshops are listed in appendix 15. Most of the conferences and seminars at
which the researchers at LEA have participated were financially supported (table 4). The LEA
has started internal seminars focusing on scientific information since 2012. Four
communications were developed in 2014 during the seminars. These seminars mainly
addressed modelisation of the growth dynamic of the population; conciliation of ecology and
genetic for the purpose of management and conservation of forest resources; fundament,
utilization and application of geostatistic for mapping agroforestry species distribution;
Environmental friendly agriculture based on community resources: A strategy for sustainable

5. Human resources and visiting research in the LEA in 2014
Human resources in LEA during 2014 are about 30 main investigators and senior scientists,
26 PhD students, actively participating to research activities within the laboratory. Moreover,
5 technicians and 3 drivers are used on permanent basis for the fieldworks. Specifically, LEA
houses 5 Full Professors (Professeur Titulaire Conseil Africain et Malgache pour
l’Enseignement Supérieur CAMES), 20 associate Professors (Maître-Conférences/CAMES),
several assistant Professors (Maître-Assistant/CAMES), assistant (PhD) and junior
researchers (MSc and BSc students). Details about these human resources are shown on the
web site of LEA (www.leabenin-fsauac.net).
Furthermore, in the course of the year 2014, LEA has welcomed 4 researchers as visitors vs.
69 in 2009, 63 in 2008 and 51 in 2007, (Figure 20). The vistors welcomed in the previous
years (2007, 2008 and 2009) were mainly students through NGOs while since 2010; the
visitors welcomed were Professors through collaboration or project.

6. General discussion and conclusion
Various types of publications were produced by LEA’s researchers in 2014 as it was the case
in previous years. It is important to notice that the total number of published papers in peer
review journal in 2014 is similar to the published papers in 2013 and 2011. The global trend
of published papers in peer review journal in LEA, increase since 1998. This can be explained
by the increase of researchers, research projects and grants holding a PhD, PhD students and
MSc student since 2006. Indeed, with more projects and grants, more papers are published
with lower cost per publication and impact factor unit. The number of published articles in
journals with Impact Factor has considerably increased since 2008. This means that
researchers are improving their publication skills and the quality of their investigation.
Another driver for this is the change in the requirements before defending a PhD thesis at the
Faculty of Agronomic Sciences which hosts LEA (having at least two published original
research paper). In the other hand, requirements for upgrading academics grades within the
CAMES system (Conseil Africain et Malgache pour l’Enseignement Supérieur) is another
important driver for increasing high quality papers within LEA. As such, the scientific
capacity of LEA research teams is increasing. Published articles in 2014 were mostly
produced in team at African level (76 % mainly Beninese). Published article in peer journal
with impact factor were mostly co-written with international colleagues while published
articles in peer journal without impact factor were morelikely written by teams at national
level. A reason for that could be the requirements for writing in English for original papers to
be submitted in most impact factor journals. Field research such as Wildlife and Grassland,
Ethnobiology, Forest and Plant ecology, Agriculture and Agroforestry were the most to
contribute to original research papers in LEA. This trend is expected to remain the same in
2015.
Publications which have highly contributed to gain the Impact Factor of the laboratory in
2014 were related to Wildlife/grassland and Risk assessement/Climate change. These
disciplines are then the most important in terms of scientific impact of LEA in 2014.
To date, almost no scientific works was done with the scientists from Latino America,
Australia, Middle East China and even Northern Africa. This suggests the need of more and
sustainable efforts for building cooperative research networks basically using interactive
research topics and funds from these parts of the world. Moreover, since 2007, few scientific
papers have been published with scientists at a regional level (West Africa). In 2014, 76% of
the articles have been co-published within national team while 18% have been co-published
with European, 4% with Asian and 2% with American scientists. As such, regional scientific
collaborations should be developed for the following years since Benin shares with its
neighboring countries similar research problems which need regional solutions and then
should be solved regionally through research activities involving laboratories in the region.
Based on the findings from the present report, it is suggested that LEA:
(1) helps for capacity building among its research teams in order to be able to publish
more scientific papers in peer review journals having a high IF;
(2) develop more research collaboration at regional level ;
(3) develop curricula in the fields of applied ecology for regional training purposes;
27
(4) continue monitoring biodiversity at continental level;
(6) develop conservation and domestication strategies for some edible and medicinal
forest and savannah resources;
(7) develop guidelines for fieldwork in applied ecology for para ecologists;
(8) monitor threatened and endangered plants and animals species at regional level.

Abstract
The current food production systems in Africa geared towards alleviating poverty and eliminating hunger, in accordance with
Millennium Development Goal number one, are faced with many challenges. These challenges include among others i) the
identification of plant species that will best suit specific environmental conditions under climate change ii) the need to
sustainably feed people and improve their livelihoods while conserving native ecosystems iii) Loss of local capacities and
know-how to sustainably manage local resources due to decades of external decision making on which crop to grow (mainly
exotic plants). To date, there is agreement that domestication of indigenous plant species for the diversification of subsistence
agriculture could play a big role in the achievement of the Millennium Development Goals. These species can be conserved
and used to halt and reverse the increasing degradation of ecosystems while providing economic opportunities, particularly in
African countries. Integration of these indigenous species into formal production systems could help establish an ecosystem
based development path in African countries. To ensure the sustainability of such a new development pathway, it is important
to guarantee availability of sufficient scientific information to guide decision making especially within the context of climate
change and socioeconomic vulnerability. In addition, policy makers will need scientific information on market incentives and
other policy instruments that can facilitate both conservation and development goals considering the MDGs. Moreover,
paradigm shift in the development concept, education and capacity building will also be needed.

Abstract
Home gardens (HGs) have being recently illustrated as promising perspectives for conservation of plant genetic resources
while contributing to improving livelihoods. However, our knowledge of local factors shaping their ownership, diversity and
structure is still limited especially in Africa. Yet, this is critical to unsure effective mainstreaming of HGs into future
conservation and production policies. Generalised linear models and multivariate analyses were used on data from individual
interviews and plant inventories spanning three bio-geographical zones to examine socio-economic characteristics (age,
gender, education level and main economic activity) affecting HGs ownership, and their effect coupled with intrinsic HGs
characteristics (size, age) on plant diversity and structure of HGs. HG ownership was age and gender-biased with the number
of female owners being the greatest. Plant diversity within HGs declined with the age of HGs for young owners, increased
with the age of HG for adults and was stable with age of HG for old people. Larger and most diversified HGs were found in
semi-humid and semi-arid zones while smaller and less diversified HGs were encountered in the humid zone. The HGs were
multi-layered (two to four layers) but based on the prevailing plant groups, three categories of HG were distinguished: Herb
based gardens, Herb and Shrub/Trees based gardens, and Palm and Liana based gardens. Prevalence of these categories was
dependent upon bio-geographical zones and HG owner socio-economic characteristics. Results suggest a cultural
responsibility of women in HGs ownership prompting that their preference and conditions will highly influence agro-
biodiversity conservation in HGs. This study illustrate the complexity of modeling influence of socio-economic conditions on
home gardening and advocates cautions if policies are to be formulated based on the current body of knowledge.

Abstract
Prioritization of medicinal plant species in conservation schemes is especially important in low income countries. This paper
aimed at developing a multivariate approach for prioritization for conservation of medicinal tree species of Wari-Maro forest
reserve (FR) in central Benin. Ethnobotany surveys were conducted in surrounding communities of this forest, using
individual semi-structured interviews with 149 people. Additionally, vegetation surveys were conducted with 42 plots
established in Wari-Maro FR for assessing the ecological parameters related to availability of those medicinal plants. Values
of ethnobotanical indices, harvesting risk index, economical importance, threat status, adaptability to climate variations and
ecological variables were compressed into principal components for each species. Results showed a total of 73 native tree
species that were reported for 94 traditional medicine uses. Among those species, 12 species were pointed out as priority
species for conservation. The most important priority species were Afzelia africana, Khaya senegalensis, Milicia excelsa and
Pterocarpus erinaceus. For three of them, people perceptions on the availability of these species were perfectly corroborated
with our ecological data. Action is urgently needed for these species. Among others, we suggest enrichment planting and
assisted rejuvenation.

Summary
Anthropogenic impact studies on tropical forests are necessary to design and develop sustainable extraction systems for both
timber and non-timber resources. However, distinguishing non-timber forest product (NTFP) harvesting impacts from timber
extraction consequences on the vegetation could be a complex work due mainly to the multipurpose status of tropical forest
species. This article critically explores the essence and characteristics of timber and non-timber uses in the Swamp Forest of

indicators to explain vegetation structure and species’ responses to anthropogenic pressures. Results suggest that the forest is
being harmed by local people’s extraction activities including both timber collection and non-timber harvesting. Finally, the
paper suggests some management options balancing socio-economic and conservation priorities.

Habitat preference and use is an important aspect of primate ecology, and an understanding of it is essential for any
conservation strategy. This study examined the activity budget, feeding ecology and selection of sleeping trees of a
population of Geoffroy’s white-thighed colobus (Colobus vellerosus). A group of 18 was followed during 72 days in the
Kikélé Sacred Forest, in the phytodistrict of Bassila in Bénin (West Africa), to understand their pattern of habitat use.
Activity budget and diet were determined using scan sampling. The structure of the habitat and the physical characteristics of
sleeping trees were described using plot surveys. Results showed that resting, feeding, moving, social interactions and other
activities accounted for 56.6%, 26.3%, 13.0%, 3.3%, and 0.7% of the activity budget, respectively. The diet was composed of
35 food sources, with items including leaves, fruits, seeds, buds, bark, flowers, gum, and inflorescences. Only three tree
species were used as sleeping sites: Celtis integrifolia, Cola cordifolia, and Holoptelea grandis. Our findings suggest that the
monkeys prefer tall (22.53 ± SD 3.76 m) and large-trunked (112.07 ± SD 14.23 cm) sleeping trees.

Abstract
This study assessed the level of bark damage on baobab trees (Adansonia digitata) as caused by elephants (Loxodonta
africana), and the possibility of finding refuges where baobab could escape bark damage within the Pendjari Biosphere
Reserve (PBR). Distributions of elephants and baobab trees within the PBR were compared using presence records of both
species taken along transect lines. Two sites (National Park vs. hunting zone) that differ in elephant density were compared
for intensity of bark damage and correlations between the intensity of bark damage and stem size of the baobab trees and
population structure of the baobab trees. Elephants and baobabs showed co-occurrence in PBR suggesting that there is
nowhere to hide for baobabs. The intensity of bark damage was positively correlated with elephant density and baobab girth.
Baobab population girth classes were not significantly different in areas with and without bark damage. Future studies should
test whether there are certain baobab genotypes that can resist elephant damage. It could also be tested whether effective
conservation of elephants in the PBR has resulted in a bull-biased population over its carrying capacity.

Abstract
Bowal, a particular form of land degradation occurs only in tropical regions. This study aims at assessing the perceptions of
farmers on the causes and consequences of bowalization and the developed strategies tocope with it in semiarid and sub-
humid climate zones in Benin. Data were gathered using semi-structured interviews and questionnaires. Representatives from
279 households of nine ethnic groups in the semi-arid zone of Benin (Peulh, Bariba, Dendi, Nagots and Mocolé) and in the
sub-humid zone (Fon, Mahi, Holli and Adja) were interviewed. Pearson Chi-square Test was performed to analyze the
perceptions on the causes, consequences and coping strategies with bowé in the two climate zones. Simple correspondence
analysis was used to evaluate the coping strategies according to the ethnic groups. Bowalization was reported to be induced
by non-adapted land use and soil erosion. An increase of farmed land and animal-drawn tillage was more perceived in the
semiarid zone as cause of bowalization. Bowalization leads to loss of biodiversity in the two climates zones. Its consequences
for the production of crops consist mainly in reducing water retention capacity of the soils, rooting difficulties for crops and
increase of soil temperature. Farmers in the semiarid zone have adopted planting of cowpea and groundnut on bowé. Adapted
cropping techniques in the semiarid zone consist in using a hoe for manual tillage and weed control. Ethnic groups of both
climate zones that depend mainly on livestock herding have to practice transhumance and use food supply for the animals.
The Bariba and Dendi in the semiarid zone modified their practices of tillage, weed control, sowing, fertilization, and
livestock feeding most. The Mahi, Holli, Fon and Adja of the sub-humid zone mostly reduced their farmland, changed the
crops and fields and adopted new off-farms activities. The Peulh mostly practiced transhumance independent from the zone.
The type of coping strategies to bowé is dependent on the climate zone and ethnic group.

Summary
An investigation was conducted in the ten phytodistricts of Benin, West Africa, in order to assess the level of morphological
variation in Jatropha curcas seed and their germination potential. Hierarchical classification of the morphological traits of
seeds identified five morphotypes, using 54% of the overall morphological information. Canonical discriminant analysis
performed on the five morphotypes revealed highly significant differences. Morphotype 1 included seeds from the
phytodistricts of Côtier, Pobè, The Ouémé Valley, and Plateau. Morphotype 2 and Morphotype 5 seeds were from the
phytodistricts of Bassila, Zou, and Borgou-Sud; while Morphotype 3 and Morphotype 4 seeds were from the phytodistricts of
Borgou-Nord, the Atacora Chain, and Mekrou-Pendjari. Significant morphological variation existed within the seeds as a
consequence of genetic make-up and/or environmental effects. Seed from Mekrou-Pendjari and the Atacora Chain were
black, smooth, light (0.67 g.seed–1), and small (1.76 cm-long and 1.15 cm-wide). Seed from Plateau, Côtier, The Ouémé
Valley, and Pobè zones were brown, rough, heavy (0.84 g seed–1), and large (1.97cm-long, 1.2 cm-wide). All seed

germination started 4 d after sowing and ended between day-7 and day-8. Seed germination timing varied significantly with
morphotype.

Abstract
Despite growing literature supporting the importance of home gardens (HG) as biodiversity hotspots, knowledge of patterns
of their contribution to conservation of threatened species and crop wild relatives (CWR) across climate and culture in Africa
is still limited. This investigation was conducted across three climatic zones to assess the floristic diversity of home gardens
and the extent to which they contribute to conservation of threatened species and CWR. Overall, 240 home gardens were
sampled and their floristic diversity assessed. The ecological importance of recorded species was determined per climatic
zone using the importance value index (IVI). A cluster analysis was performed to group the species according to their IVI-
values and a principal component analysis helped to identify the most important species. 285 species were inventoried
throughout the study area. Home garden species’ diversity globally declined from the drier to the wetter zone but was highest
in the transition zone. The average number of species found per HG was 10.1 and varied weakly across zones (9.07, Guineo-
Congolean zone; 10.77, Sudano-Guinean zone; and 10.53, Sudanian zone). The most important home gardens species in the
Sudanian, the Sudano-Guinean and the Guineo-Congolean zones were respectively: Abelmoschus esculentus (L.) Moench
and Hibiscus asper Hook.f.; Solanum lycopersicum L. and Zea mays L.; Ipomoea aquatica Forssk. and Senna occidentalis
(L.) Link. They were mainly vegetables and used as food and/or medicinal plant species. Twenty CWR and twelve threatened
species were recorded and were also mainly used for food and medicinal purposes. Thorough research on socioeconomic
factors supporting possession of HG and choice of managed species as well as indigenous management strategies of HG and
dynamic of traditional knowledge related to HG may help to deeply assess home gardens’ effectiveness in biodiversity
conservation.

Abstract
This study was set up to examine the effect of plot patterns on the accuracy of phytosociological characterization of tropical
vegetation. Fifteen and twenty square plots of 1 ha were demarcated, respectively, in woodland and dense forest in Bénin.
Each 1 ha plot was divided into 100 quadrats of one 100 m2. Species of trees in each quadrat were identified and recorded.
The cost in terms of time required to record tree species in each 1 ha plot and five random quadrats in a 1 ha plot were also
recorded to compute the mean inventory effort for a team of three foresters. From the 100 quadrats in a 1 ha plot, fourteen
independent subplots of square and rectangular plots with different sizes were considered by grouping together adjacent
quadrats of 100 m2. Eigen analysis was carried out to compare the subplots. Moreover, the relationship between the relative
loss of accuracy (RLA) and the size of subplots was modelled. Plot size highly influenced the RLA (P < 0.05). Findings
indicated that the square plots of 1500 and 1000 m2 with an inventory effort of 0.35 and 0.20 man-days per subplot,
respectively in tropical dense forests and woodlands appeared to be the most efficient in the phytosociological
characterization of woody vegetation.

Abstract
There is increasing interest in home gardens (HGs) as biodiversity hot spots. However, knowledge on how sociocultural
characteristics and environment influence knowledge and management of HG species is still limited. Eliciting these links
helps illustrate how HG could conserve biodiversity. This study addressed the following hypotheses: (i) age and gender shape
61
the knowledge of HG species; (ii) knowledge on HG species varies across phytochorological zones; (iii) use values (UVs) of
HG species are correlated to their ecological importance and (iv) HG species is mostly used for food and medicinal purposes.
Data were collected from 285 HGs, across three phytochorological zones of Benin, using semi-structured interviews.
Quantitative analyses were performed using ethnobotanical indexes and statistical tests. Our results confirmed our
assumptions except for hypothesis (i). Gender and age did not determine knowledge on HG species. Nevertheless, noticeable
differences were encountered among the zones regarding species, knowledge and use types. UV and ecological importance
were highly correlated. Our results support the point that HGs sustain food and medicine supply while contributing to
conservation of local biodiversity. However, with modern mutations, HGs are unlikely to be preserved if they are not actively
mainstreamed in production and conservation policies.
Keywords: gender; age; use value; ecological importance; West Africa.

Abstract
Despite the numerous work conducted on integrated crop-livestock systems, very little is known about factors determining
farmers’ trend to integrate. Our study aimed at a socioeconomic characterization of endogenous crop-livestock integration in
Benin and identification of determinants of farmers’ decision to use these practices. Two hundred and forty farmers were
surveyed in three agro-ecological regions of Benin. A semi structured questionnaire was used to collect information on
farmer’s characteristics, production factors and agriculture and breeding by-products valorization practices. On the basis of
main links between both productions, three integration levels (no integration, NI: 36%; partial integration, PI: 55%; total
integration, TI: 9%) were identified and characterized according to socioeconomic characteristics of farmers. Then the
multinomial logistic regression technique was used to predict the integration level of a given farmer in function of its
socioeconomic characteristics. The three integration levels differ significantly (p<0.001) according to variables such as
membership in farmers’ association, educational level, weight of agricultural experience, farm equipment and size of animal
herds. The decision by a farmer to choose the total integration type significantly depends (p <0.001) on the size of his cattle
herd, his membership in farmers’ association, the weight of his agricultural experience and his equipment value.

Abstract
We undertook a survey of 112 cattle farms in the periphery of Cotonou in Benin, with the aim to characterize the diversity of
the production systems and to better understand herders’ feeding strategies and perspectives. We used the categorical
component analysis and two-step clustering techniques to classify the farms into homogeneous groups. The adaptive strategy
of a given farm was predicted through logistic regression analysis technique. Four distinct farm types were identified as
follows: large integrated agro-silvopastoral (17%), small agro-silvopastoral (28%), pastoral (30%), and silvopastoral (25%).
Irrespective of farm type, low availability, and difficult access to pasture due to increased crop/vegetable farming, climate
variability and urbanization were commonly reported by all herders. Current coping strategies included the use of lowlands
pastoral resources and exploring new grazing routes. Future strategies included moving animals towards rural locations and
significantly (p < 0.001) depended on farm type and its proximity to urban centers.

Abstract
This paper addressed temporal changes in floristic composition, plant communities’ structures and productivity of grasslands.
The study was conducted in the Hunting zone of Djona in the Transboundary Biosphere Reserve of W (TBRW) Benin. For
these purpose 30 plots of 900m² were used and “phytosociological relevés” were done following ecological uniformity,
floristic homogeneity and samples representativeness to established plants communities. For biomass estimation, 30 plots of
100 m² were used. Results showed that the greatest productivity value (8320 ± 0.21 kg DM/ha) was observed in Andropogon
gayanus-Schizachyrium sanguineum grassland. The dominant life forms in all plants communities of the study area are the
phanerophytes followed by therophytes. For chorological types, all plants communities are dominated by the species of the
Sudanian base element and species with broad distribution. The identified life forms and chorological types showed an
evolution of the post farming pastures to woodlands and savannas vegetation, which explains the current floristic
composition of the area. Moreover, it will be possible to model the impact of grasslands exploitation on the viability of the
62
protected area particularly in the context of climate change and for this, it’s important to undertake a long-term study in order
to take into account all variations and all causes of these variations.

Abstract
Rangeland vegetation before protective measures intensification (2002) was compared to rangeland vegetation 10 years after
(2012). To reach our objectives, 32 phytosociologiques plots were considered in Transboundary Biosphere Reserve according
to Braun blanquet method. Data were collected in 2002 and in 2012. Linear releves were also done according to Daget and
Poissonnet methods. An NMS (Nonmetric Multidimensional Scaling) perfomed on the two survey matrices allowed us three
plants groups: Andropogon pseudapricus and Isoberlinia doka of woodlands, Hyparrhenia involucrata and Stereospermum
kunthianum of herbaceous savannahs and Hyparrhenia involucrata and Grewia cissoides (2002). Loxodera ledermannii and
Isoberlinia doka, Hyparrhenia involucrata and Combretum glutinosum and Andropogon gayanus et Combretum glutinosum
in 2012. With linear releves data pastoral value were calculated for the two periods. Life form and chorological type spectrum
were done and analysis. This analysis revealed the predominance of phanerophytes in 2012 and can be explained by
reduction of anthropic pressures on rangeland vegetation since intensification of protection measures. We also remarked that
the dominance of Sudanian base element species and testify the adherence of our data zone to the sudanian area. The high
pastoral value observed in 2012 showed a better quality of forage in the rangeland. All diachronic analysis proved that a
decrease of anthropogenic pressure and also proved the progressive evolution of rangeland vegetation of Transboundary

Abstract
Study aims on the one hand to know the microbial quality of chicken viscera, fish viscera flour and to select the packaging
with the best suitable preservation condition. The flours were divided in three packages (plastic, jute bag and can) and three
environments (refrigerated, ventilated, non-ventilated) for microbiological monitoring. A total of 36 samples of each flour
were monitored and analyzed for two months, according to ISO and AFNOR standard methods for research of the following
germs: Escherichia coli, yeasts, moulds, total and thermotolerant coliforms. The results obtained show that plastic bag and
can packaging in refrigerated or non-ventilated environments are favourable for the preservation of both flours for two
months. The results obtained on the production day of flours highlight the lack of germ spoilage indicator (E. coli,
Staphylococcus aureus, sulphite-reducing anaerobes and coliforms). The microbial load was 2.95 and 2.84log10cuf/g
respectively for chicken viscera and fish viscera flour.

Abstract
Since many foods consumed by human are from animal, the risk of germs transmission through the consumption of products
from animals like pig and poultry nourished with contaminated flours remains high. This study aims firstly to access the
hygienic quality of two flours Moringa oleifera and Azolla filiculoides and then to select best stocking conditions for their
conservation. Those flours were produced and stored in three packing in three different environments for microbiological and
phytochemical analyses. On the whole, 36 samples of each flour were followed and analyzed during two months time,
according to standardized methods ISO and AFNOR to research anaerobes sulphito-reducers (ASR), coliforms
thermotolerants, Escherichia coli, yeasts, moulds and Staphylococcus aureus germs presence. The results showed that storing
in plastic bag and tin in refrigerated and non-ventilated environments are suitable for conservation during two months
without anaerobes sulphito-reducers (ASR) and Staphylococcus aureus presence.

Le présent article de revue fait état des études relatives aux utilisations des ressources alimentaires non conventionnelles
utilisées en alimentation animale. Il met l’accent sur la description, la composition et les intérêts agronomiques de ces
dernières. Dans la recherche des informations sur les ressources alimentaires non conventionnelles plusieurs travaux
scientifiques publiés ont été consultés et leur synthèse a été faite. L’examen des résultats de recherche a révélé l’utilisation
des ressources alimentaires non conventionnelles comme une alternative face aux coûts élevés des ressources
conventionnelles qui sont pour la plupart importées vers les pays tropicaux. Les travaux traitant de l’utilisation des ressources
alimentaires non conventionnelles et particulièrement de Azolla Spp, Moringa oleifera, son de riz, viscères de poulet et de
poisson dans l’alimentation des animaux sont parcourus. Leur standardisation permettrait de les rendre applicables en milieu
paysan. Ces ressources pourraient ainsi constituer une alternative de choix face aux coûts des aliments conventionnels
utilisés en production animale.

Abstract
Ethnopharmacological relevance: The review is implemented to take stock of the situation of scientific research in Benin and
Central and Western Africa on the ligneous medicinal plant in order to pinpoint the investigation on the priority species for
ethnobotany and conservation researches. Aim of the study: This study aims at: (i) identifing the most important ligneous
species used frequently in traditional medicine in Benin and its surrounding countries for human as well as animal ailment
treatment; (ii) assessing how haversting of ligneous medicinal plant part is affecting their survival. The ethnobotany studies
implemented in Benin were most focused on ligneous species and the ethnopharmacology ones reported in addition many
other ligneous species; thus, this review aims to find out those plants need the in depth study. Materials and methods: A total
of 38 published articles carried out in Benin and Central and Western Africa were exploited and had permitted to compute the
relative importance (RI) and the plant part used value (PUV) for each ligneous plant. Both index allowed at identifying the
most employed medicinal plants according to the medicinal proprieties of their parts harvested. Results: The number of
ligneous medicinal plant used in Benin and in its surrounding stood at 263 species belonging to 193 genera and 61 families.
Beninese country and its surrounding used commonly 99 ligneous species as medicinal plants. All the ligneous were used for
146 medicinal proprieties categorized into the 17 groups and occurred in all the parts of ligneous: leaves (66.92%), barks
(42.21%), roots (39.54%), stem (28.14%) and fruit/seed (19.77%). The most important values of relative importance (RI)
where obtained at 14 principal medicinal plants that were majority subjected to ethnobotanical studies in depth. The highest
values of the plant part used (PUV) were also obtained at the ligneous plant with high relative importance value and
expressed the impact of plant part harvest for various ailment treatments, on the species survival. Conclusions: This review
shows that the many ligneous plant were mostly and commonly used as soon as in Benin and in its surrounding countries.
Some ligneous plant as Morinda lucida and Zanthoxylum zanthoxyloides had most widely used. According to medicinal
proprieties attributed particulary to their roots, those plants are seriously vulnerable and worth studying in depth in
perspective for their conservation in Benin.

Abstract
The pastoral breeding plays a preponderant role in the economy of the sub-Saharan Africa countries. With a great diversity
of species bred, it contributes to food and nutritional security of rural and urban households. In Benin, beef cattle breeding
are essentially nomadic. Numerous studies and meeting focused on it in order to solving the difficulties it brings and
numerous legal dispositions were adopted for this same target. This study aims at making the inventory of these different
studies in order to bring out the constraints confronted by the system. A documentary review was done. Several documents
on transhumance in Benin and the region were consulted and the data synthesized. This synthesis allowed to characterizing
the study area, then the historic and characterization of nowadays transhumance. The tools used are the triangulation. A
diachronic analysis also allowed to underlining the administrative and management of transhumance in Benin. The local
breeding system studied following the model of Lhoste et al. (1999) showed that the first papers on transhumance were
writing in 1905. The practice still used by Fulani, came in Benin with them. Moreover, the results showed that transhumance
is confronted with pasture, climate variability, the statutory texts, the conflicts and the availability of pastoral infrastructures.
The study also showed that transhumance is still under the heavy influence of crops systems mainly during drought season.
This drives to the change and orientation of this system to protected area. Besides, the breeders adopted this current
transhumance mode to exploit the annual growth of the animals which occurs during rainy period.

Abstract
Sustainable conservation of tropical resources required understanding of their distribution, assessment and definition of
conservation priorities. In tropical areas, wild palms are highly valued keystone resources with growing demand for both
subsistence uses and commercial trade. Here we focused on eight such species (Borassus aethiopum Mart., Eremospatha
macrocarpa (G.Mann & H.Wendl.) H.Wendl., Hyphaene thebaica Mart., Laccosperma secundiflorum (P.Beauv.) Kuntze,
Phoenix reclinata Jacq., Raphia hookeri G.Mann & H.Wendl., Raphia sudanica A. Chev., and Raphia vinifera P.Beauv.).
This study tested (i) how those palm species distributions could have extended under future scenarios and (ii) if species are
effectively conserved currently and under future forecasts in their native distributional area. Finally, we defined spatial
priorities for the species conservation. Available bioclimatic and soil data layers were used for the modelling with maximum
entropy approaches and resulting maps were overlaid with the protected areas network. Results showed that much of the
distribution of the species will remain stable albeit with some expansion and retraction in some species; relationships with
protected areas networks suggest that protected portions of species distributions will also remain stable. The areas identified
as highest conservation priority differ between built models even though the highest prioritization areas holding most palm
species are located along the coast (from Guinea to Nigeria). Further development of these analyses could aid in forming a
more complete picture of the distributions and populations of the species, which in turn could aid in developing conservation
strategies for African futures for this botanically important family.

Abstract
Hyphaene thebaica (dum palm) is an important tree species that grows wild in the semi-arid regions of tropical Africa.
Increased knowledge about the effect of stresses on the propagation and establishment of the plant is needed to optimise its
domestication. This study assessed the physical characteristics of H. thebaica fruits harvested from three phytodistricts in
Benin. The germinability of the seeds, before and after water-soaking and removal of the seed coats, was tested and the
number and size of leaves produced in resulting seedlings was measured. Hierarchical classification of the fruit
characteristics revealed the existence of three morphotypes. A Factorial Discriminant Analysis, performed on those
morphotypes, revealed highly significant differences (P ≤ 0.001). Morphotype 3 (48 seeds) had the highest rate of seed
germination (49.99 %) and the highest width of the leaf (28 mm) in 154 d of experiments. Morphotype 2 and Morphotype 3
(48 seeds each) seedlings had the highest number of leaf (2 leaves) whereas only Morphotype 2 seedlings had the highest
length of the leaf (35 mm). Results from the Analysis of Variance revealed that the time of germination and water-soaking
had a significant effect (P ≤ 0.05) on seed germination. The study also showed that the growth of the seedling differed with
time of germination, and the differences varied with morphotype. These results may be used to improve propagation and
conservation strategies of this species in areas of origin.

Abstract
African palm species are plant resources being widely used for many purposes. However, factors affecting their uses remain
poorly understood. This study tested (i) how site or socioeconomic factors affect palm use among and within a specific area,
and (ii) how each category of use relates to a particular palm species. An ethnobotanical survey was conducted on 1357
informants across different zones of Benin, using semi-structured interviews. Quantitative analysis used regression analysis
on ethnobotanical indexes for assessing impact of these factors on uses, and principal component analysis to investigate
relationships between palm species and use categories. The number of reported uses varied significantly among species. The
reported use value was explained globally by the site. Socioeconomic factors like sex, age and length of residence affected
differently the reported use for palms within sites. Last, categories of uses were specific to palms and influenced by
socioeconomic characteristics of informants within sites. We suggest that site effect should be considered in ethnobotanical
study for effective sustainable conservation of palms species in the western Africa.

Abstract
Anthropogenic disturbances and climatic variations are presumed to alter species population structures. In this study, we
assessed the population structure of the endangered species, Afzelia africana across gradients of climate and human
disturbances. Dendrometric variables such as regeneration and tree density, mean diameter, basal area and height and stem
diameter distribution were recorded at national scale in forest reserves located in three different climatic zones in Bénin. A
canonical discriminant analysis was applied to describe the species' population structure across climatic zones and
disturbance levels. Relationships between the principal components (structural parameters of A. africana stands) and climatic
variables and disturbance levels were assessed using Pearson correlation. Significant differences were found in the structural
parameters between the disturbance levels, mostly in the Guinean zone. Structural parameters also differed significantly
across the three climatic zones, with the Guinean zone recording the highest values. The effects of disturbance levels on
structural parameters depend on the climatic zone, and vice versa. The results imply an interaction between climatic zones
and disturbance levels. In the Guinean zone, the tallest and biggest trees were found at the low disturbance level. However,
along the climatic gradient (towards drier regions), trees were shorter and smaller irrespective of disturbance level. Further,
the tallest and biggest trees were found at lower altitudes.

Abstract
This study assessed endogenous knowledge and impact of human disturbance on the abundance of two underutilized wild
fruit tree species: Drypetes floribunda (Mu¨ll. Arg.) Hutch. (Euphorbiaceae) and Mimusops andongensis Hiern. (Sapotaceae)
in the Lama Forest Reserve (LFR) in southern Benin. A survey was conducted with 145 randomly selected people amongst
the surrounding communities of LFR in order to assess the endogenous knowledge of the species. One hundred square plots
were established in the forest for characterizing species abundance in different habitats according to human disturbance
degree. Results indicated that this species has multiple uses and either local knowledge on their uses or their organ plant uses
depend on social factors. A densities assessment suggests a negative effect of human disturbance on the abundance of both
species. Results support the need to envisage conservation and sustainable use strategies as perspective policies.

Abstract
Over the world, one of perspective challenges in biodiversity conservation is how to meet effective conservation of
threatened species. In this frame, endangered African tree species is becoming a priority that should attract development of
conservation strategies. Since biotechnology is developing rapidly as conservation strategies of biodiversity targets these last
decades, it has been questioned to know (i) the current situation concerning biotechnology and endangered African tree
species, (ii) the problems that prevent using of biotechnology in conservation of endangered African tree species and (iii)
perspectives to help biotechnology to conserve endangered African tree species. Thus an overview on these questions showed
that endangered African tree species have not taken advantages of biotechnologies strategies yet. Few biotechnologies
researches based on endangered African tree species have been undertaken until now. This state of knowledge is explained by
some difficulties that have been highlighted. Those difficulties concerned mostly characteristics of seeds of endangered
African tree species, cost of biotechnologies strategies and bad integration of biotechnology discipline with other ones. They
are preventing wide use of biotechnology strategies to conserve endangered African tree species. Considering them, some
recommendations have been addressed as perspectives of conservation of endangered African tree species by biotechnology.

Abstract
High blood pressure (HBP) is a recurring disease, source of morbidity and mortality which are increasingly high in Benin.
HBP expensive care in modern medicine restricts access of his treatment to poor populations which are obliged to use plants.
The aim of the present study is to identify the antihypertensive plants used in Beninese pharmacopoeia by using
ethnobotanical surveys. Thirty six traditional healers were interviewed using individual interviews. A total of 23 plant species
used by traditional healers were shown to have antihypertensive properties. They belong to 16 botanical families. The most
used species were Parkia biglosa (38.88 %), Allium sativum (33.33 %), Allium cepa (30.35 %) and Cassia sieberiana (27.77
%). The root was the most used plant part (36 %) while the decoction (80.35 %) was the main mode of preparation of drugs
usually orally administered (95 %). Factorial Correspondence Analysis (FCA) applied to the ethnic group’s frequencies of
citation showed Parkia biglobosa as the most used species by Nago, Cassia sieberiana by Anii and Fulani, and Securidaca
longepedunculata by Lokpa. A chemical composition and toxicity of these plants could help to confirm their efficacy in order
to take adequate decisions for their valorization.

Abstract
This study is a contribution to the knowledge of the habitats of Dialium guineense (Willd) through botanical and ecological
investigations. To do this, 150 plots of varying sizes were installed in different plant communities of Benin territory once
Dialium guineense willd appears. Thus, 60 plots are installed in different forests (sacred dense dry, clear) and savannas; 14 in
the fields and fallow; 68 in the gallery forests and 9 in home gardens. In each area, floristic inventories included all woody
and herbaceous species abundance coupled to their dominance coefficient. The forest inventory data collected were: dbh H
10 cm, the height; the average recovery, the height and shape of the barrel, the height of the crown and its radius North-South
and East-West, the number of branches and stem form. The ecological descriptors such; slope, disturbance, moisture, soil
texture, width of rivers, the influence of wildlife and activity traces were recorded. Multivariate analysis (DCA and CCA)
allowed distinguishing of four plant communities and gradients distribution. The results of the performed DCA gave 4 plant
communities. The density of D. guineense is strong in the galleries (47 stems / ha), followed by home gardens and houses (25
stems / ha). Regarding the structure height and diameter of the species in all habitats, the distribution is skewed left. It is
therefore important to know the characteristics of the species habitat to promote the planting of native species

Abstract
Beninese forests that are legally protected or traditionally continue to face severe pressures. The sacred forests formerly not
included in the IUCN categories are the subject of an international resurgence in regard to their conservation of species. The
sustainable management of forests requires prior understanding of the mechanisms of regeneration of species they support.
This study aims to evaluate the effect of holes on the regeneration of woody species in two community-based forests
(Kodjizou and Bahazou) for sustainable management. Both forests have been sailed by-looking holes. For each hole
encountered area and were originally identified. A floristic survey was also carried out for each hole. Of descriptive statistics
were performed to characterize the gaps. The relationship between the size of the holes, species richness and density of gap
regeneration was modeled unthreading Box-Cox transformations. Finally, a principal component analysis was performed to
describe the relationship between the origins of gaps and frequency of species encountered. A total of 84 holes have been
inventoried. The average area of 132.08 m2 ± 44.58% and varies between 18 m² and 290 m². The density of holes is about 2
holes / ha. Three origins of gaps were inventoried: Chablis, cut and cut + windfall. The origin of the gap influenced the
species diversity of regeneration, the highest differences were obtained in the gaps created by cutting or cutting + windfalls
are also wider. Eleven species were identified in the gaps. Both species are more profitable regions Berlinia grandiflora and
Dialium guineense. The results of the principal components analysis indicated that the gaps created by cuts and windfalls
both more species (Dialium guineense, Isoberlinia doka and Spondias monbin). The study revealed a strong pressure on
forests in relation to the number of holes counted. It is therefore necessary to strengthen the protection by limiting fraudulent
cuts. Conduct a study on the dynamics of the recovery of the vegetation in order to better understand the process of
reconstitution of natural forests.

Abstract
Palm oil mill wastes (POMW) are well known to be rich in phosphorus, nitrogen, calcium, magnesium, sodium and
potassium. This study was carried out in 2012 to assess farmers' practices on utilization of POMW in agriculture in the south
of Benin. A total of 335 palm oil mills from the Communal Union of Palm Oil Producers were randomly selected and
surveyed using a questionnaire. The use of POMW as fertilizers depends highly (p < 0.001) on the nature of fertilizers used
by the farmer. The use of empty fruit bunches (EFB) and fibre as fertilizers depends on the knowledge of the farmer about
their application directly in palm plantations or indirectly through composting. These wastes were applied by local
application (76.5%) or mulching (33.3%). The use of EFB and fibre produced depends on their use in plantations (p < 0.001).
POMW were composted by heaping, by breeding pigs on POMW and in pits. Breeding pigs on POMW involved placing
POMW in a pig pen with added vegetables. The pit method consisted of making a hole. The POMW are put in the pit. After
the short rain season, the compost obtained can be used. Composting is a process unknown by 67.5% of mill owners. The
difference between those who know about and use composting, and those who know it but do not use it is based on their
knowledge of composting advantages. The use of POMW in composting is mostly developed in Ifangni District (Plateau
Department).

Abstract
Palm oil is one of the most valuable oleaginous trees worldwide. Wastes from palm oil production are used for many
purposes (soap, fire starting cake, butter…). While researchers have paid attention to the sustainability of the palm oil mill
environment, there have been no studies about the importance of each kind of waste in relation to its sustainability. To
analyze these questions, a survey was conducted in Southern Benin with a random sample of 335 palm oil mill owners. An
ethnobotanical index was used to evaluate the importance and value of palm oil mill wastes in palm oil production. A double
Principal Component Analysis was performed to characterize palm oil mill waste using categories of palm oil production.
The study reveals that palm fiber and empty fruit bunches were plays the same social important (p>0.05) to mill owners, with
the Importance Value at 0.52 and 0.45, respectively. The importance of these wastes varied within palm oil production. The
quantity of empty fruit bunches and palm oil mill effluent used depended on the amount generated and use value to mill
owners. At the same time, the quantity of fiber used depended only on its use value. When fiber was used for many purposes,
the mill owners did not use all the quantity produced. Palm oil mill waste was more valorized in soil fertilization in Ouémé.
The discharge of palm oil mill effluent in Plateau, Couffo and Mono contributed more to environmental pollution than palm
oil mill solid wastes.

Abstract
Composts made from empty fruit bunches, Fibre, poultry manure and cattle dung and composted under cover were applied to
evaluate the growth and yield of three indigenous vegetables (Amaranthus hybridus, Lycopersicon esculentum, Corchorus
olitorius) grown on ferralitic soil. The experiment was carried out in ‘‘‘Farm GBEMAWONMEDE’’, a palm oil mill located
in the District of Sakete, Department of Plateau, South-East of Benin Republic, and was submitted to Guinean climate. The
trials for each species consisted in a split-split plot design with two levels of composting method (without cover or under
cover) and the types and rates of compost as secondary factors: 24 treatments in 4 replicates in total. The number of leaves,
the height and stem diameter of 5 plants of Amaranthus hybridus per plot were measured weekly during five weeks. The
same parameters were measured on 5 plants of C. olitorius at the 16th, 23rd, 32nd and 41st days after sowing. The height and
stem girth of 3 plants of L. esculentum, randomly selected on each experimental plot, were weekly measured during seven
weeks. At the end of the experimentation, the marketable yield of Amaranthus hybridus and C. olitorius was measured as the
total number of L. esculentum fruits, total number of healthy fruits and weight of healthy fruits. There was no significant
effect (p<0.05) of composting method on these vegetables growth. The type of manure incorporated during the composting of
palm oil mills solid wastes, significantly affected Amaranthus hybridus height and stem girth. The stem girth increased by
8.57, 9.7 and 6.16% respectively on the 2nd, 3rd and 4th week after transplantation (WAT). When treated with the cow dung,
the plant height increased by 8.6, 9.7 and 6.2% whereas their stem girth decreased by 7.7, 5.2 and 4.7% respectively on the
2nd, 3rd and 4th WAT. The effect of the type of manure varied within the composting methods range. In fact, composts made
with poultry manure under cover were more suitable for Amaranthus hybridus growth than the other composts while
composts made without manure and those made with cow dung without cover were more efficient for C. olitorius growth.
The growth of all these vegetables increased with the compost application rate and 20t/ha allowed such growth. The use of
composts with poultry manure (19.2t/ha) induced more marketable Amaranthus hybridus yield than composts without
manure (18.4t/ha). The effect of compost application on C. olitorius and tomatoes yields was significant at 10t/ha compost
application rate The total number of tomatoes fruits depended significantly (p<0.05) on the compost application rate. The
highest number of tomatoes fruits obtained was 19.4 at 20t/ha as compost application rate.

Abstract

Long-distance dispersal (LDD) of plants is rare, difficult to measure but disproportionately important for various ecological
and evolutionary processes. Dispersal of seeds of gallery forest trees in savanna provides an opportunity for the study of
colonization processes and species coexistence driven by LDD. Investigations were carried out on 91 isolated trees along four
gallery forests sampled in the Biosphere Reserve of Pendjari, Benin. The abundance of adult trees within nearest gallery
forest was combined with functional traits (species maximum height, seed weight, morphological adaptation for dispersal by
wind, water, birds and mammals) to explain the floristic composition of forest seedlings and saplings under isolated trees and
in savanna. Stepwise negative binomial regression was used to identify the most significant variables explaining abundance
of seedlings and saplings beneath isolated trees and in savanna and then derive colonization from seedlings and persistence
from saplings. The maximum height of species and seed weight explained the highest proportion of variance in species
colonization. Morphological dispersal syndromes by wind and birds had poor explanatory importance. Species rare in gallery
forest had higher potential to colonize new environments through LDD while abundant species had higher persistence
abilities. Contrary to the predictions of the seedling-size effect, small-seeded species dominated the sapling stage. The
findings revealled the strong dependence of LDD and subsequent colonization and persistence processes on species traits
specialized for a variety of dispersal vectors. They also suggest that LDD towards isolated trees established far away from
gallery forest can be difficult.

Abstract
The spotted-necked otter (Lutra maculicollis) is believed to be declining across its range and, in Benin, has recently been
listed as endangered. In Benin, the spotted-necked otter is largely restricted to the south of the country, where it is threatened
by a number of factors, including conflict with fishermen. Understanding the nature and extent of this conflict, and the impact
that it has on local fishermen, as well as identifying feasible mitigation strategies, represents a critical challenge for
conservation managers. This study documents otter damage experienced by 30 fishermen in the Hlan River, in the Southern
Benin wetlands. We performed hierarchical classification analysis using Ward distances to categorize fish species according
to the level of otter damage suffered, and used generalized linear models to identify predictors that best explained otter
damage. Our results suggest that of the 16 fish species commonly caught by fishermen in the Hlan River, otters favoured the
most valuable species (but these were also the most abundant in the catch). However, although otter damage was extensive,
monthly total income loss attributable to spotted-necked otter damage (including fish loss and damage to equipment) was
estimated at only 9% per fishermen (considerably lower than the 30% reported by a preliminary survey of 163 fishermen in
the same area). Our model showed that otter damage increased significantly with the number of adult fish captured by
fisherman while the cost of otter damage increased with the length of time that the fishing equipment was left unattended. We
suggest that otter damage could be reduced if fishing equipment were checked at least twice a day by fishermen, and
recommend a maximum interval between checks of 700 minutes (12 hours). Long-term sustainable management of these
conflicts will require an integrated approach taking into account socio-economic, political and environmental dimensions.
Key Words: conflict, otter, fisheries, equipment setup duration.

Abstract
Multiple uses including tourism, hunting, and agriculture around protected areas can be a serious complication for wildlife
management. We calculated habitat selection indices (Manly’s alpha) for 10 bovid species in the Pendjari Biosphere Reserve
in Benin, West Africa, to assess if habitat use differed in each bovid species between hunting and non-hunting zones.
Presence/absence data was used in resource-selection functions based on a Generalized Linear Mixed effect Model to
examine factors that explained bovid species distribution. We observed stronger avoidance of open habitat types in the
hunting zone than in the non hunting zone for the hartebeest (Alcelaphus buselaphus), oribi (Ourebia ourebi), roan
(Hippotragus equines), kob (Kobus kob), waterbuck (Kobus ellipsiprymnus defassa) and reedbuck (Redunca redunca). In
contrast, in grey duiker (Sylvicapra grimmia), red-flanked duiker (Cephalophus rufilatus), bushbuck (Tragelaphus scriptus)
and buffalo (Syncerus caffer) we found no differences in habitat use between hunted and non-hunted areas. This may indicate
that the latter species show more pronounced ecological and behavioural plasticity. Further, resource selection of bovid
species on a small scale was influenced by other factors such as habitat structure, landscape characteristics, and human
disturbance. This preliminary assessment of bovid habitat relationships in West Africa suggests that human hunting activities
may cause species to alter their habitat selection. We therefore suggest habitat models may need to incorporate this source of
variation if they are to accurately predict habitat use or distribution of a species.

Résumé
La performance de production de biomasse du ver de fumier Eisenia foetidaest évaluée en station sur 5 différents substrats.
Les fumiers de bœuf, de mouton et de lapin, et le sol ferrallitique de la station expérimentale étaient comparés avec le sol du
site de collecte des vers de fumier, un sol hydromorphe sableux et noir (substrat contrôle). Les fumiers étaient mélangés à
volume égal au sol ferrallitique de la station alors que le substrat contrôle et le sol de la station d’expérimentation étaient
conservés comme tels. Les vers de fumier étaient suivis chaque semaine et leurs nombres, leurs performances de croissance
et les couches de substrat explorées étaient rapportés. Les résultats ont révélé que le fumier de bœuf était le meilleur en
production de ver de fumier suivi des fumiers de mouton et de lapin. Le sol ferrallitique pur a induit une importante
diminution du nombre et de production de biomasse. Concernant l’exploration des couches de substrat, le sol ferrallitique et
le sol contrôle étaient très rapidement explorés en comparaison aux autres substrats contenant des fumiers montrant un lien
avec la qualité des substrats et les performances rapportées. La production de vers de fumier dans les petits agrosystèmes est
donc possible et pourraient contribuer à la gestion de la fertilité des sols fermiers de même qu’ils peuvent servir comme
complément protéinique pour les animaux de la basse cours des petits fermiers contribuant à la gestion intégrée de la fertilité
des sols.

Abstract Many regions in Africa are currently being converted from subsistence to cash crop farming such as cotton. Agricultural
intensification is usually accompanied by increased use of pesticides, which can have an impact on non target organisms.
Bats are particularly sensitive to insecticide loads while providing substantial ecosystem services as predators of herbivorous
insects. In this study, pesticide residues in bats in a landscape in northern Benin were investigated, which spanned a land use
gradient from an agricultural zone dominated by cotton farms, through a buffer zone, and into a national park. Insecticides
used in cotton cultivation, such as endosulfan, chlorpyrifos, flubendiamide, and spirotetramat, aswell as persistent
insecticides such as bis (4-chlorophenyl)1,1,1-trichloroethane (DDT), lindane, and aldrine, were analysed. Insecticide
residues detected in bats comprised DDT, endosulfan, and their corresponding transformation products. Maximum
concentrations in the sampled bats were 11.2 mg/kg lipid of p,p′-DDE (median: 0.0136 mg/kg lipid) and0.797mg/kglipidofβ-
endosulfan(median: below detection limit [DL]).While insecticide concentrations were below lethal concentrations our data
suggest that DDT had probably been recently used in the study region, and larger scale use would pose an increased risk for
bat populations due to the high biomagnification of DDT.

Abstract
Adansonia digitata is a multiple purpose tree for African populations. This study investigated in Benin the role of pollination
in fruit production and thereby flower abortion reduction. Baobab populations were characterized in the three climatic regions
covering tree DBH, height, crown diameter, flower sepals and petals. Nectar productions were measured, as well as flower
visitation by bats, pollination success and subsequent fruit production. Bats contribution to fruit production of baobab was
measured with caged and free flowers. We reported that baobab trees’ DBH, height, crown diameter sizes and flower organs
were overall statistically different from one region to another increasing in size from the southern to the northern region of
Benin. The Central region of Benin (Dassa) showed the lowest value of nectar production and flower visitation but the
pollination success of flowers reported in the succeeding weeks was overall similar for the three regions. Significant
contribution of bats to the pollination success of baobab flowers was showed with the lower values reported for caged
flowers. Fruit production of baobab distributed in DBH classes were comparable between Southern and Northern regions but
very low in the Central region suggesting the importance of bats visits that seem to be influenced by the nectar production.
Large DBH classes contributed most in fruit production of baobab trees. Bats’ pollination reduces flower abortion increasing
fruit production to guaranty the conservation of baobab in natural habitats.

Abstract
This study assessed the combined effect of the size and shape of inventory plots on the analysis of the density and diameter
structure of saplings and juvenile trees. Thirty square plots of 400 m2 were randomly laid out and each one was divided into
400 quadrats of 1 m². Stem number of recruits was recorded for all tree species and their diameter at breast height was
measured in the quadrats. Seven types of subplots with different shapes and sizes were considered by grouping adjacent
quadrats of 1 m². The Green index was used to assess the spatial distribution of regeneration and Weibull distribution was
applied to model stem diameter distributions. Box–Cox transformations and weighted regression were used to model the
relationship between the Green index, the plot patterns and the standard error of the estimation of the regeneration density.
The same analyses were applied to model the relationship between the Green index, the plot patterns and the mean absolute
error of the shape parameter of the Weibull distribution. The Green index and the plot size had a significant impact on the
error of the regeneration density estimation. For clumped distribution of individuals, the plot shape had a significant impact
on the error of their density estimation. As for stem diameter distribution, only the plot size had a significant effect on the
mean absolute error of the stem diameter structure. The rectangular plots and square plots of 100 m² (14 m × 7 m and 10 m ×
10 m) appeared more suitable for an effective structural analysis of woody species regeneration in the tropical dense forest
for an aggregated distribution and a random distribution, respectively.

across 10 socio-cultural groups. We tested and validated the hypotheses that (1) age, gender and socio-cultural groups are
predictors of TK and plant ethnobotanical use value; (2) bigger bamboo species are more expensive on the market. Bamboos
were used for 44 purposes but the common food use of bamboo shoots was not reported. Men and older people had more
knowledge and valued bamboos more than women and younger people respectively, indicating that they are key stakeholders
for conservation actions. The culm was the most harvested part of bamboos and its selling price was location- and size-
dependent. The implications of these results are discussed with respect to conservation and management strategies for
bamboos.

Abstract
Spatio-temporal dynamics of land cover and degradation factors were analyzed using Landsat images of 1972, 1990 and
2008, remote sensing and GIS tools, in the W National Park and its periphery in the north-western part of Benin. The
objective of this study is firstly to analyze the dynamics of land cover between 1972 and2008,and secondly, to determine the
vegetation degradation factors. Socioeconomic surveys were performed in the surrounding villages of the W reserve.
Socioeconomic surveys were conducted in the surrounding villages of the W National Park. The supervised classification by
the maximum likelihood was applied. Two transition matrices helped to highlight the conversions undergone by the various
units of the land cover. Forests vegetation decreased from 22.70% in 1972 to 17.00% in 2008. Degraded galleries forests
almost nonexistent in 1972 have been constituted and increased from 0.60% in 1990 to 2.85% in 2008. Thus, dense forests,
clear forests and woody savannah are suffered a regression from 0.23% in 1972 to 0.09% in 2008 and 17.90% to 12.91%
respectively. Hence, trees and shrubs savannah decreased slightly from 73% in 1972 to 66.65% in 2008 while fallows and
fields raised from 1.38% in 1972 to 13 97% in 2008, more than 10 times its initial size in 1972. Demography, agriculture, and
overgrazing are the three main factors of degradation of the W Transboundary biosphere reserve and its peripheral.

Abstract
This study researches the local agroforestry species of high socio-economic and cultural values to rehabilitate degraded areas
of the W National Park of Niger and its surroundings in Benin. About 136 farmers including Dendi, Djerma, Fulani,
Gourmantche and shrugged are interviewed on species saved in the fields according to their abilities to: (i) restoring the soil;
(ii) improving farmer income; (iii) feeding man or animal; (iv) treating diseases. Principal Component Analysis of
farmers’objectives and uses indicate 41 spared wood species with 63.4% known in the soils restoration processes and 34.1%
in income improvement. Responses show that Vitellaria paradoxa (65.4%), Piliostigma reticulatum 37.5%) and Borassus
73
aethiopum (24.3%) more improve soil fertility while V. paradoxa (81%), Tamarindus indica (36%) and Parkia biglobosa
(26%) more improve incomes. Plant organs are largely solicited with the exception of the roots in the cases of V. paradoxa
and Diospyros mespiliformis. The species organs usage depends or not on ethnicity. The fruits of P. reticulatum are used to
heal wounds and feed with in Hausa and Fulani. Leaves and fruits of B. aethiopum serve the Dendi, Djerma and
Gourmantche to make mats, ropes and traps while the bark is strictly medicinal. Restoring the soil fertility and improving
farmers’ income in Karimama may rely on V. paradoxa, P. biglobosa, T. indica, B. aethiopum and Sclerocarya birrea. P.
reticulatum, is specific in the soils restoring processes. Hausa and Fulani avoid the roots usage favoring the biodiversity
conservation for the benefit of the degraded ecosystems restoration. Further studies are needed on the seeds viability as well
as the species restoration’ costs and constraints determination.

Abstract
In the W National Park and its periphery in the drier Sudanian zone of Benin, serious economic and environmental problems
due to soil erosion are becoming more frequent. Erosion and land degradation in this area is characterized by a massive soil
losses phenomenon called "donga". The objective of the current study is to identify the erosion and donga origin, have a
better understanding on erosion and donga processes and precise the mechanisms which lead to their evolution. Data were
collected using individual and group interviews, field visits and observations, longitudinal and transversal soil profile and soil
infiltration capacity analysis. Erosion and donga phenomenon in this part of Benin have at the beginning anthropogenic
causes. Several evidence or signs are in favour of this assumption. Natural factors such as slope, rainfall aggressiveness and
wind come to accentuate the phenomenon. Donga occurrence is the result of the physical characteristics of soil and
vegetation. The crusting of soil surface is the first phenomenon by the combined effect of rain and wind. The transversal
slopes are low and induce sheet erosion. Three main processes determine dongas evolution after their appearance namely
water erosion (sheet erosion and regressive erosion), wind erosion and erosion due to animals.

Abstract
The study was carried out on the site of Koussin and Lélé in the southern Benin, exploring the efficiency of the supply of the
pearl and super granule urea (46%) and NPK 15-15-15 for rice production in the inland valley. Specifically, the study aims to
assess the effect of the different forms of urea and NPK 1515-15 on the growth and yield parameters of two inland rice
varieties (IR841 and NERICA-L14) widely adopted in cultivated lowland of Benin. The experimental design is a split-plot
with two rice varieties, four forms of fertilizer (pearl urea + NPK; pearl urea + super granule NPK; super granule urea + pearl
NPK and super granule urea + super granule NPK) in four replications. The growth and yield parameters were assessed.
Super granule urea + super granule NPK and super granule urea + pearl NPK have significantly (P <0.0001) induced higher
plant height, numbers of tiller and rice grain per panicle compared with the other treatments whatever the rice variety.
However, mean yields of paddy rice and straw were significantly higher (P < 0,0001) for super granule urea + super granule
NPK (paddy rice yield : 5,52 ± 0,26 t/ha ; straw yield: 12,19 ± 0,54 t/ha) and super granule urea + pearl NPK (paddy rice
yield: 4,82 ± 0,22 t/ha ; straw yield : 10,79 ± 0,61 t/ha). In general with these treatments, the highest yields were recorded
with IR841 rice variety. Conclusion and application: The super granule fertilizers are recommended for improving rice
production in the inland valley as they improve substantially the yields. In order to improve the efficiency of these fertilizers
especially the sources of nitrogen, the study suggests to supply urea super granule + NPK super granule or urea super granule
+ pearl NPK to improve growth and yields parameter of IR841 rice variety.

Abstract
Response to nitrogen fertilizer of 2 grass species, Pennisetum polystachion and Setaria sphacelata, and one legume
Tephrosia pedicellata was studied in northern Benin. The 3 species are native in Sudanian grasslands and occur on tropical
ferruginous soils. The experimental plots were fertilized with a basal dressing of potassium chloride and triple
superphosphate before testing nitrogen fertilizer at rates of 0, 60 and 120 kg/ha N, respectively. The highest biomass was
produced with 120 kg/ha (4.98, 2.13 and 1.1 t/ha DM for Pennisetum, Setaria and Tephrosia, respectively). The highest
number of pods per plant with Tephrosia was produced with the control plot (35.75 pods per plant) and the lowest with an N
74
rate of 60 kg/ha (23.75 pods per plant). The highest tussock diameters for Setaria and Pennisetum were 76.4 and 71.9 cm,
respectively, at an N rate of 120 kg/ha. These 3 native forage species showed good performance under cultivation.

month of October. Measurements of tufts density and the recovered surface of stumps and biomass harvesting were carried
out in 18 plots of Brachiaria ruziziensis previously identified and exclosed. Plots aged 2 years, 5 years and 10 years were
selected taking into account the following three conditions: mown plots; lower grazed plots; heavily grazed plots. The results
showed that the average number of tufts per square meter was higher for all pastures under conditions of overgrazing in non-
grazing condition. The average was 7.26 tufts m-2 in overgrazed areas cons 5.30 tufts m-2 in mowed areas. The average
density of the tufts in the pastures in lower grazed condition was 6.46 tufts m-2. The recovering surface of stumps and
biomass production changed inversely to the density of tufts, depending on age and grazing intensity. The recovering surface
of stumps average in mowing condition was 170.53 cm2 m-2 cons 121.93 cm2 m-2 in overgrazed condition. The average
recovering surface of stumps in lower grazed condition was 133.55 cm2. The elevation of grazing intensity is accompanied by
a decrease in biomass productivity and the recovering surface of stumps, and the increase in the number of tufts.
Key words: Brachiaria ruziziensis, grazing, plateau of stump, tufts density.

Abstract
Nutrional values of two anthelminthic forage species namely Boerhavia diffusa and Khaya senegalensis were determined by
in vivo digestibility tests. The study was performed on 12 non-castrated rams sheep with an average weight of 23 ± 0.6 kg
vaccinated, dewormed, divided into two homogeneous groups of six subjects for each plant and housed individually. The
experiment lasted 25 days divided into two phases: adaptation and data gathering which is about food, refusals and faeces
samples weighing. Chemical analyzes and bromatology of all samples collected were made. The forages’ net energy was
calculated from the organic matter constituents’ digestibility according to the INRA system. Phytochemical screening of
leaves of B. diffusa and K. senegalensis shows the presence of secondary metabolites. On the other hand, galenic tannins’s
level is much higher in K. senegalensis than in B. diffusa. That negatively affects its water’s level, its intake, its nitrogen’s,
fat’s, and energy’s digestibility coefficient cross-check to B. diffusa (p <0.1). Indeed, B. diffusa’s net energy level for growth
and feeder were higher than K. senegalensis’s (p <0.1). B. diffusa’s leaves had a better nutritional value than K.
senegalensis’s and could improve ovines’s growth by appropriate supplementation.

Abstract
Pentadesma butyracea is a multipurpose resource facing heavy pressure. P. butyracea and its natural stands are characterized
by actors with multiple and often conflicting interests. Socio-cultural factors that affect non-timber forest products use
sustainability include property rights of resources, diversity of their users and access regulations by socio-cultural positions.
A stakeholder analysis was used to: (i) identify and categorize actors that intervene in the species management, (ii) highlight
actors’ interest conflicts, and (iii) propose solutions for a better resource management. Focus group and individual interviews
were combined to identify stakeholders and cluster them in categories based on their own perception. P. butyracea was a
resource with unspecified property rights. According to the degree of destruction their activities have on the species viability,
stakeholders were dispatch up into three categories: stakeholders whose actions are destructive in the short term, those with
destructive actions in the medium term, and actors whose action are destructive in the long term. There was convergence of
interests between actors belonging to the same category whereas conflicts were noticed between those who were in different
categories.

Abstract
The production of teak (Tectona grandis L.f.) seedlings in Southern Benin was studied from an analytical perspective
combining the production techniques and the financial outcomes, in order to address the issue of poor seedling quality which
affect field performance of forest plantations. A survey was carried out in the Atlantique department, using the snowball
sampling method. Semi-structured interviews were hold with 55 nursery holders; and the following data were collected:
activity organization, techniques of production, the costs borne, and the sales revenues. The stages of the technical itinerary
of teak seedling production were as follows: seed supply, dormancy-breaking, sowing, cares for young seedlings (mainly
watering, weed and pest control). Weaknesses were found across the technical itinerary which might affect seedling quality.
These include the use of tout venant seeds from non selected trees, and the use of inadequate polyethylene containers. The
financial analysis showed that nursery holders were getting a positive return from their activity. The net revenue from the
production of 1000 seedlings ranged between USD 41.21 and 53.30. The seedling production system will perform better with
the provision of technical assistance to farmer for access to good quality seeds, and further retraining on the production
techniques.

Abstract
The study analysed the consumption of processed pineapple products in southern Benin from an analytical perspective
combining consumption patterns and the expectancy-disconfirmation framework. The low processing of agricultural products
does not enable Sub-Saharan Africa’s country to exploit the full potential of agriculture for their development. The objective
of this study was to identify upgrading opportunities in the value chain with focus on processing. A survey was carried from
December 2012 to February 2013 among 250 respondents randomly selected in five cities of southern Benin; and data were
collected based on structured interviews. Dried pineapple, jam, syrup, juice, and cocktail were the processed pineapple
products available on the market. Beverages, especially the juice were by far the main processed pineapple products. Factors
influencing the consumption of pineapple-based beverages included household size, education level, and monthly income.
The motivations driving the purchase of processed pineapple beverages by consumers were: seeking of competitive price,
local beverage, natural beverage and therapeutic beverage. There was a margin for the value chain to upgrade products and
service and increase the price while staying competitive. A strong marketing and advertisement campaign is essential to
support a wider knowledge of processed pineapple products by consumers. Product traceability is a prerequisite for export in
regional and international markets. This makes the certification of the value chain a critical issue.

Abstract
Invasive plant species are today among the biggest threats to integrity of many ecosystems including that of the protected
areas. Climate change may exacerbate the negative effects of invasive plant species. Here, we used the Maximum Entropy
model to project habitat suitability for Lantana camara L., an invasive plant species under current and future climates in the
national protected areas network of Benin. The models were run using bioclimatic data and data on soil type. Nineteen
percent of the total land in the protected areas network was highly suitable for L. camara under current climate. Highly
suitable areas under current and future climates cover about 65 % of the Pendjari Biosphere Reserve, the major wildlife
sanctuary in Benin. Other bio-reserves such as W National Park, Lama, Agoua, Dogo-Kétou, Atchérigbé, Mékrou and
Kouandé Forest Reserves were also suitable for the species. Presence of L. camara in the protected areas represents a great
potential threat to the global food webs being conserved. Based on these results, areas with highly suitable habitats are at high
risk of invasion by L. camara, and should be accorded high priority when formulating appropriate management strategies.

Abstract
Medicinal plants are important in the life of African populations and there is nowadays an increasing need to gathering
information related to them. In order to highlight the importance of termitaria to local populations, we investigated within the
Pendjari Biosphere reserve the medicinal uses made from plant species found in association with them. We laid out plots in
fields and fallows surrounding the Pendjari National Park to assess fifty six termitaria and identify plant species on them. By
using specimen and local names of species, group interviews were conducted with the 3 major ethnic groups in the Biosphere
reserve. Results show that people perceive termitaria as fertilization materials, and plants in association with them are
considered more efficient in traditional medicine than those collected in mounds vicinities. Indigenous people used, for
various medicinal purposes, twenty-two (22) plant species consisting of 21 woody and 1 herbaceous belonging to fourteen
(14) families. Species used as medicine were relatively different according to the ethnic group. Furthermore, Combretaceae
was the most used plant family. A total of thirty (30) diseases and illnesses were treated by plants, and bark was the most
used part followed by leaves and roots. We suggest that conservationists and other scientific advisers use our findings to well
define conservation programs and increase people’s awareness on the sustainable management of termitaria and their
ecosystems.

Abstract
This work explores factors supporting people perception about mine site restoration and phytoremediation. Phytoremediation
is one of the most eco-friendly restoration strategy emerged since the last two decades but studies on local people perception
on this restoration strategy are scarce. To fill in this gap, data were collected from mining stakeholders using a structured
questionnaire administered through snowball sampling method. We used Multiple Correspondence Analysis as implemented
in the software XLSTAT to visualize relationship between participants’ characteristics, their view on mine site restoration
and phytoremediation. Results clearly show out that people perception on mine site restoration is influenced by mining
activities effects on health and region attractiveness. Phytoremediation (65.21%) was rated positively with regard to its
environment potential, aesthetic and consideration for future generation followed by fillings and excavating. Restoration
strategy costs have no effect on people choice and participants prefer use of shrubs as vegetation component of
phytoremediation to reach their restoration objective.

Abstract
Commercial thinning is a silvicultural treatment that is attracting much interest in the context of limited wood supplies.
Further, this interest is increased by the fact that many planted or pre-commercially thinned stands are now becoming
available for the treatment. To study this treatment profitability, data used came from 35 pairs of permanent plots (control vs
thinned) that were established in operational thinnings and surveyed over ten years post-treatment, in natural black spruce
stands. Wood production values and harvest costs were used to determine stand Net Future Values (NFV) ten years after
thinning. Using stepwise multiple regressions, thinning intensity and pre-thinning merchantable basal area were selected as
the two most important variables, which explained 66.7% of the variation in stand NFV. With 9% annual discount rate, NFV
was significantly higher in commercially thinned stands ($21325/ha) compared to controls ($18382/ha). Thus, commercial
thinning could increase black spruce stand profitability in Quebec in stands with a high initial basal area or when high
thinning intensities are used. In these conditions, treatment profitability would result from an earlier income, reinvested at a
high interest rate. Although the study results confirm MFFPQ recommendations, there is a need to pay more attention to the
market value of thinning products to make commercial thinning profitable.

Abstract
Bitter and sweet African bush mango trees belong to the family Irvingiaceae and produce valuable non-timber forest products
in humid lowland areas of West and Central Africa. The bitter and sweet types are treated as distinct taxa at the variety or
species level. They have not been studied in the western part of their distribution range, and many aspects of their large-scale
utilization remain unknown. In this study, we link differences in socio-cultural groups to the agroforestry status of bush
mango trees in order to identify the key factors influencing their abundance and conservation in the study area. First, we
gathered uses and local management strategies from nine main socio-cultural areas in Benin and Togo, part of the Dahomey
Gap. Second, occurrence data were obtained throughout the Gap and imported into DIVA-GIS and MATLAB to calculate the
spatial pattern of the density and analyse its structure and variation relative to three factors: the country, the
phytogeographical zone and the dominant soil category. Third, agroforestry system characteristics and farmers’ social status
relative to 841 trees were used in a multinomial logistic regression to identify anthropogenic factors driving the intensive
cultivation of bush mango trees. Finally, the impact of socio-cultural activities on extent and density of bush mango tree
populations was analysed. In the entire study zone, the sweet mesocarp is consumed and the endocarp of bush mangoes is
commercialized. The application of endocarp-based diets and socio-therapeutic uses are common to communities in Benin.
Sweet bush mango trees are generally found either in home gardens or cultivation fields where they may occur at high
densities (up to 1020 trees per 25 ha). Bitter trees, however, are confined to the Volta forest region in Togo and occur at low
densities (< 462 trees per 25 ha) in the wild, sometimes in protected areas, in forest gardens and in fields. This indicates a
clear difference in cultivation methods between the bitter and sweet trees. Farmland status, farmer socio-cultural group and
type of bush mango trees determined the cultivation intensity. The fact that small farmlands are converted into sweet bush
mango tree orchards indicates that farmers actively cultivate bush mango trees in the study area. Diversity of indigenous
knowledge, however, is not correlated either to intensive cultivation or domestication efforts and local genetic conservation
program. Where slash and burn agriculture and intensive collection of fruits jeopardize bitter trees, traditional fishing systems
(using bush mango twigs), a traditional selection strategy, and intensive land commercialization severely threaten sweet bush
mango tree genetic resources.

Abstract
This phenological analysis of bitter and sweet bush mango trees is part of their biosystematics. It supports the species
distinction hypothesis postulated by Harris (Bull J Bot Nat Belg 65(1–2):143–196, 1996) and Lowe et al. (Mol Ecol 9:831–
841, 2000). Abstract African Bush Mango trees are priority food trees in Sub-Saharan Africa. The unclear distinction
between bitter and sweet fruited trees is still subject to taxonomic debate. This hinders their effective use and conservation
programmes. This study investigates differences in phenological behaviour between bitter and sweet fruited populations and
their taxonomic implications. Monthly phenological description data on seven populations of bitter or sweet bush mangos
across Benin and Togo were used to assess within and between mango type phenological diversity, to discriminate bitter and
sweet trees and to evaluate their responses to environmental factors. The phenological states differentiating bitter and sweet
trees were identified and individual trees were classified based on the discriminating phenological characters. Finally,
phenological variation was analyzed with time of the year, soil type, type of bush mango tree, and climatic zone.
Phenological diversity varies significantly among populations. Bitter and sweet trees have consistently different phenological
states. Bitter trees have a lower phenological diversity for all phenological phases throughout the year compared to sweet
trees, possibly due to their limited distribution range in the study area. The tree types also differ in their reproductive
responses to environmental factors, but did not respond differently to soils. These results support the hypothesis that bitter
and sweet trees represent different taxa and we suggest for efficient conservation purpose to consider them as different
species.

Abstract
Plant species are basic component of agro-biodiversity and a complex situation created by their own ability to disperse; and
the rapid changes of land use and climate is endangering their efficient conservation and use. In order to increase knowledge
of bitter and sweet African bush mango trees (ABMTs) (Irvingia spp.: Irvingiaceae) and support small-scale farmers in
78
establishing uniform plantations, germinability of earlier fruited trees was assessed. Germination rate and speed, from both
systems were analysed in order to differentiate bitter and sweet bush mango trees and identify types of seeds suitable to
overcome the climatic hindrances for uniform plantations establishment in the Dahomey Gap, a drier eco-region where
savannah reach the sea coast including Benin and Togo. Fresh seeds of both bitter and sweet fruited trees, showed the highest
growth performance (98 - 100%). Seed germination speed significantly depended on the drying level and the germination
system (sunshine versus covered condition). The speed was higher for fresh seeds in closed condition, confirming bush
mango seeds as typically recalcitrant, but not strictly photoblastic. Results also demonstrated that bush mango seeds do not
require specific treatments for optimising germination. Germination did not depend on mango tree type (bitter or sweet) and
fresh seeds were the best material for establishing viable and uniform plantations.

Abstract
Biological diversity, with its key role in ecology, culture, agriculture, nutrition and healthcare, remains the most valuable
heritage for humans. In healthcare, there are three main ways in which plants are valued: foods, drugs and cosmetics. Fruits,
leaves, roots and sap, with their nutrients and secondary metabolites (e.g. proteins, carbohydrates, minerals), provide human
with vitamins, antioxidants and particular useful natural substances. In spite of the fact that the healthcare system in Africa
mostly relies on traditional botanical extracts, their in-depth biochemical characterization and standardization, as well as the
anti-nutritional and poisonous factors of these extracts, are profoundly lacking. Caution is needed when using botanical
extracts in personal healthcare. At the same time, more investigations should be undertaken to improve knowledge as well as
the safe utilization of those extracts.

Abstract
Geostatistics was developed in the 1960s as a robust statistical approach that better handles spatially or temporally or even
spatiotemporally distributed data. It works in powerful Geographic Information System (e.g. MATLAB) and was initially
designed for soil/earth-related data, mostly in mining, but with successful application in hydrology, petroleum, pollution and
environmental sciences, marine biology, epidemiology, ecology, etc. Recently, from 2000s geostatistics is increasingly used
in ecology and natural resources management particularly in the field of species distribution modelling. Similarly to other
classical statistical approaches, geostatistics modelling started with traditional exploratory analyses (uni and multivariate
analyses) and categorical variables as well as co-evolution of regionalized data lead to exciting statistical development. As
such, the use of geostatistics in agrosystem analysis offers a possibility of getting a spatially broad view on food tree species’
on-farm conservation and on how they are shaping land use systems. Therefore based on the purposely violation of variable
independence (a main requirement in classical statistical analyses) spatial dependence of bush mango tree’s densities
(Irvingia spp., Irvingiaceae) helped characterize the spatial structure of local communities conservation effort and predict the
density over non sampled areas in the Dahomey Gap. Basically, density values within sampled 5 x 5 km² in the variogram
analysis and the kriging estimation techniques helped achieve this goal. Small patches of high densities were detected within
a globally low density pattern, with no directional particularity. Even though the geostatistical analysis relies on intensive
sampling technique, it remains on of the most consistent methods in this field tree species density mapping and the co-kriging
estimation technique might refine our results.

Abstract
Biosphere Reserve Pendjari (RBP) in Benin is home to many known for their therapeutic actions species. Given their
importance and the growing pressures on, it is important to appreciate the role of protected species conservation areas. This
study analyzed the population structure and the conservation status of species and four galactogenic emmenagogue
(Adansonia digitata L., Khaya senegalensis (Desv.) A. Juss. , Vitellaria paradoxa Gaertn. Parkia biglobosa and CF (Jacq.)
R. Br ex G. Don f.). Floristic and mensuration data were collected in the hunting area and land (fields and fallow) on the
outskirts of the RBP. Phytosociological surveys and tree measurements taking into account the regeneration were carried out
79
in 55 plots installed for this purpose. The diametric structures (J and bell) and vertical differ from one species to another and
from one medium to another. Natural regeneration of Adansonia digitata and Khaya senegalensis is almost zero in both
environments, while Vitellaria paradoxa is high (305 stems / ha in the hunting zone Pendjari (ZCP) and 70 stems / ha in soils.
Parkia biglobosa in this regeneration is low in both media (13 stems / ha). It appears that the level of conservation of these
species varies in each community. Thus, Adansonia digitata has a low level of conservation and Parkia biglobosa would be
better preserved in the earth if human pressures decreased. Khaya senegalensis and about Vitellaria paradoxa , retention is
better in ZCP. The development of a zoning plan for a participative management by the proper authorities would be indicated
for a durable conservation of the phytogenetic resources of Biosphere Reserve of Pendjari.

Abstract
This study assessed endogenous knowledge and impact of human disturbance on the abundance of two underutilized wild
fruit tree species: Drypetes floribunda (Müll. Arg.) Hutch. (Euphorbiaceae) and Mimusops andongensis Hiern. (Sapotaceae)
in the Lama Forest Reserve (LFR) in southern Benin. A survey was conducted with 145 randomly selected people amongst
the surrounding communities of LFR in order to assess the endogenous knowledge of the species. One hundred square plots
were established in the forest for characterizing species abundance in different habitats according to human disturbance
degree. Results indicated that this species has multiple uses and either local knowledge on their uses or their organ plant uses
depend on social factors. A densities assessment suggests a negative effect of human disturbance on the abundance of both
species. Results support the need to envisage conservation and sustainable use strategies as perspective policies.

Abstract The study Monodora myristica local name (Sasalikun, Ariwo) is addressed in order to develop this species medicinal and
nutritional value widely used by people of Benin. To this end, this study has focused on the evaluation of traditional
knowledge Monodora myristica populations in the lower valley of Ouémé. To know the uses of endogenous populations
Monodora myristica, ethnobotanical surveys based on questionnaires and focus group interviews were carried out nearly 120
people from different professional categories. The answers of the respondents per-mitted to calculate ethnobotanical indices:
diversity index survey (ID) Value consensus on the types of uses (CTU), consensus value for collection sites and the value of
fairness User (EU). Following the results, three categories of uses have been identified for Monodora myristica: medicinal
use, commercial, medical and magical. Among these forms of use, medicinal use is widely recognized in populations with

Abstract
Olive colobus (Procolobus verus), the smallest of all colobine monkeys, is not well documented in Benin. From 2008 to
2010, we conducted surveys through the range of the species in Benin to determine the current distribution and assess the
threats to its survival. To achieve the objectives, we interviewed local people from 88 villages, visited local fetish markets
where animal’s parts are sold, and then, conducted surveys in 16 forests. Results indicated that olive colobus is not as rare as
we thought: its presence is confirmed in several previously unknown sites. Its range extends from south to north Benin
between 6°30 and 9°45 north latitude and covers an area of 25,403 km². Various forms of threats including hunting for bush
meat and extensive agriculture, affect the survival of olive colobus in Benin. According to these threats in its current range
and the lack of attention in olive colobus’s protection, a priority has to be accorded to its conservation.

Abstract
Cowpea (Vigna unguiculata (L.) Walp.) is a legume whose leaves can be used in cattle feed. The objective of the study was
to assess changes in mineral contents of cowpea leaves during its growing cycle and to identify the best period of harvest in
soil and climatic conditions of the Boundji area. Methodology and results: Cowpea leaves were collected at 1, 2 and 3 months
after sowing. Dried in an oven at 60 ° C to constant weight, they were subjected to chemical analysis in the laboratory. The
results show that the levels of various minerals behave differently during the development cycle of the plant. Conclusion and
application of results: Overall, the levels of major elements and trace elements can cover the needs of growth, maintenance,
reproduction and milk production of animals during three months of the cycle. However the period of one month after sowing
seems most favorable to harvest the leaves.

Abstract
Therapeutic effectiveness of association Combretum micranthum G Don (Combretaceae) and Cochlospermum tinctorium A.
Rich. (Cochlospermaceae) in the coverage of the viral hepatitis B. The coverage of the viral hepatitis B lives one problem
concern especially in developing countries because of the inaccessibility and the very high cost of the modern treatment. In
front of it, the appeal to the plants of the traditional pharmacopoeia establishes a remedy for many patients. The objective of
this study is to evaluate the effectiveness of one of these remedies with Combretum micranthum leaves and Cochlospermum
tinctorium roots. To this end, the preparation of the both of plants was administrated to 24 patients from 17 to 42 years old
and carriers of Ag HBs (decoction of C. micranthum and powder of C. tinctorium). The patients were examined for 90 days.
Of the analysis of the results, a clinical and biochemical improvement of the state of the patients was noticed. After seven
days of treatment, a forgiveness of the clinical signs has been observed; a significant decrease of transaminases was obtained
at all the patient's from the first month of treatment (ALAT: 25, 96±11, 51, p = 0,000; ASAT: 31, 25 ± 10, 72, p = 0,000).
Furthermore, the disappearance of the AgHBs was noted at 4.7 % of the patients at the end of the study. These results must
be completed by other investigations for formulating a efficient therapeutic form which will contribute to take care over viral
hepatitis B.

Abstract
Bowalization is a particular form of land degradation and leads to lateral expansion of ferricrete horizons. The process occurs
only in tropical regions. In this study, the most adapted and resistant species towards climate change were identified on bowe.
The 15 most common bowé species of the subhumid and semi-arid climate zones of Benin were submitted together with
significant environmental variables (elevation, current bioclimatic variables, soil types) to three ecological niche modelling
programmes (Maxent, Domain and GARP). For future prediction (2050), IPCC4/CIAT and IPCC5/CMIP5 climate data were
applied. Asparagus africanus, Andropogon pseudapricus and Combretum nigricans were identified as the most resistant
species for ecological restoration of bowé in the semi-arid climate zone and Asparagus africanus, Detarium microcarpum and
Lannea microcarpa in the subhumid climate zone. The ‘Pull’ strategies were identified as appropriate for ecological
restoration of bowé in Benin.

Abstract
Bowal, is degraded land surface characterized by ferricrete exposure due to soil surface erosion. This study aims at assessing
the spatial distribution of bowé in Benin and the physicochemical differences between bowé and soil of adjacent woodlands.
Bowé surfaces were identified during field investigations and mapped. Soil samples were taken on the bowé surfaces and
nearby woodland. Mann–Whitney test was applied to analyze the different physicochemical characteristics of bowé and
woodland. The results show that bowé were directly related to ferruginous soils and rainfall regime. Bowé soils are
characterized by significantly lower values of electrical conductivity, organic matter, extractable phosphorus, silt and total
nitrogen than woodland soils, while potassium exchangeability of bowé soils is higher. Bowé can be expected wherever
ferruginous soils and/or ferricretes are observed under unimodal rainfall regimes condition. The disaggregation of bowé
ferricretes may improve the soil physicochemical characteristics and sustain the regrowth of forest under more humid
conditions.

Abstract
Bowé are particular form of degraded land where ferricrete, a hard erosion-resistant layer, is exposed. This study
investigated vegetation characteristics of bowé (species composition, life form, chorological type, and plant family) in the
semiarid and sub-humid climate zones in Benin. In both climate zones, bowé sites were characterized by grassland and
savanna. The species composition on bowé varied according to the climate zone. Woody species were frequent on bowé in
sub-humid (51% of the total species recorded) than in semiarid (44%). Geophytes, hemicryptophytes and phanerophytes were
frequent on bowé in the sub-humid than in the semiarid climate zone. The difference between the two climate zones on the
occurrence of therophytes on bowé was not significant. The frequency of chamaephytes was higher on bowé sites in the
semiarid zone. Afro-tropical, Afro-Malgache, Pluri regional African and Pantropical chorological types were frequent on
bowé than in woodlands in each climate zone while the opposite was found for Guineo-Congolian and Sudano-Zambesian
chorotypes. Plant families such as Amaranthaceae, Zingiberaceae, Chrysobalanaceae, Connaraceae, Loganiaceae, Moraceae
and Ochnaceae were only found on bowé in the sub-humid climate zone, while Convolvulaceae, Loganiaceae, Rhamnaceae,
Araceae, Colchicaceae, Cucurbitaceae, Olacaceae, Pedaliaceae, Amaranthaceae, and Cyperaceae were only found on bowé in
the semiarid zone.

Abstract
Desertification and land degradation are worldwide problems affecting soil, vegetation and thereby livelihood of the rural
population. Bowal (plural bowé) is a particular form of degraded land that has occured in tropical West Africa since the
earlier 1900s. Bowalization leads to ferricrete exposure unusable for farming. The results showed a persistence and
increasing rate of degraded land (farmland and degraded savanna on which bowé occur) and decreasing of the natural
vegetation. The future scenarios also predict the same trend. A total of 26% of the area cover with natural vegetation (forest,
woodland and tree savanna) would be converted to farmland and degraded savanna towards 2050 if we assume the dynamic
recorded from 1975-1990. Towards 2050, 31% of these land cover would be converted in farmland and degraded savanna
when considering the dynamic observed in 1990-2010. Thus bowalization would persiste and increase towards 2050.
Promotion of the best practices developed by some farmers to prevent and cope with bowalization in West Africa would help
to limit the land degradation in this zone.

Abstract
This study examined the phenotypic variation and the modalities for integrating Moringa oleifera in agroforestry systems in
southern Benin in order to contribute to sustainable management of the species. Morphological characterization of M.
oleifera based on measurements taken on the trees, leaves, leaflets and fruits, and ethno-botanical survey on cultivation
techniques and management of plantation of the species were performed. The morphological analysis showed significant
variation between populations of M. oleifera in the phytodistricts considered in relation to tree height, leaf length, petiole
diameter, length and width of leaflets (P <0.001); length, median diameter and fresh weight of pods (P <0.01). In the
phytodistricts considered in the southern Benin, the culture of M. oleifera was mainly by cuttings (92.85 to 97.8%) and row
planting (91.83 to 98.03%). The adoption rate of M. oleifera varied between 89.79 and 97.05%. There was significant
dependence between the management practices and the willing for adoption (ΔG2 = 5.59, P = 0.018), between management
practices and the origin of planting materials (ΔG2 = 5.50, P = 0.019).

Abstract
Caesalpinia bonduc L. is an important medicinal plant threatened by overexploitation. In the present study, the impact of
climate on seed morphology, germination capacity, seedling and plant growth of of C. bonduc were evaluated. A total of
2000 seeds were collected in Sudano-Guinean and Guinean climate zones of Africa and their length, width, thickness, weight
and colour were recorded. A hierarchical classification and canonical discriminant analysis were applied to the above traits of
seeds from the different climatic zones. An analysis of variance with repeated measures was applied to seeds morphotypes
identified by the hierarchical classification to test for the effect of these morphotypes on seed germination, seedling and plant
growth. Hierarchical classification helped to identify four seed morphotypes. Canonical discriminant analysis performed on
these morphotypes revealed highly significant differences. Morphotypes 1 and 3 comprised green seeds from Sudano-
Guinean zone while morphotypes 2 and 4 gathered grey seeds from Guinean zone. Morphotype 3 had the longest seeds while
the shortest seeds were from morphotype 1. The heaviest seeds were found in morphotype 4 whereas the lightest ones were
from morphotype 1. Seeds of morphotype 4 were the thickest, while the less thick ones were grouped in morphotype 1.
Moprhotype 3, consist of large seeds from Sudano-Guinean zone was superior in terms of seedling and plant growth among
all morphotypes and should be the best choice for planting purposes of the species.

Abstract
Caesalpinia bonduc is overexploited and threatened due to its importance in medicine. This study aims at assessing on farm
seedling productivity of C. bonduc by aid of simulation modelling in order to design its appropriate plantation techniques,
harvesting intervals, and soil conditions. Data were collected from nursery and field experiments by measuring stem height,
collar diameter, number of leaves and tap root length during 180 days. The simulation model was based on a metabolic pool
type model calibrated first to simulate the observed growth data from the nursery (calibration). Following it was used to
simulate the growth of plants from field experiments, first by an optimization of the utilization of leaves or roots only, and
second by an optimization of the utilization of both leaves and roots at the same time at different plant densities and nitrogen
levels. The models show that in order to optimize the utilization of C. bonduc it should be planted at high densities with high
nitrogen levels. Leaves and roots harvesting should take place every 50-60 days, and maximum 15% of the biomass of roots
and leaves should be harvested at each harvesting event.

Abstract
Many efforts have been made in recent decades to provide urban forestry a tool of conservation plant sources and sustainable
development of cities. In southern countries, these efforts are more focused on conventional reforestation and education
without much considers the factors that determine the survival of the trees.This study on the Porto-Novo city in Bénin, is a
better understanding of the viability of urban trees, including those planted by analyzing the constraints of the medium. Lands
atimages were used to determine state changes in vegetation cover in 2003 and 2013 An inventory of forms of mutilation on
the trees is associated with a survey of populations to link the urban practices and their causes on the viability of urban trees.
For data processing, normalized vegetation index is calculated in ENVI 5 and mapped in ArcGIS10. Chi Square test and
correspondence analysisare performed under R. The results show a decline in the normal state and moderate vegetation and
an increase in stress states and mineral areas. Depending on the population, it is the anthropogenic activities (P= 0.001) and
planning conditions (P= 0.01), which are currently the factors significant constraint strees. The consequences are biologically
and landscape esthetically. The inclusion of such information is necessary for a better future of urban forestry in the city.

Our research thesis endeavor to understand use patterns, propagation modes, ecology and spatial distribution of black
tamarind in Benin. Thus, different methodology approaches including questionnaire and field data collection were used to
fulfill our goals. Ethno botanical and economic data (herbal drugs, selling prices of organs of the species) were collected from
individual interviews and ‟focus group”. Environmental data (slope, observed disturbances, soil texture) were identified on
site. The multiplication of D. guineense was tested using seeds scarification and quantifying coppice. The habitat of the
studied species was characterized through ecological and floristic analysis of vegetation. The diameter and height structures
were made using the Weibull distribution with two-parameters followed by coefficient of skewness. The influence of climate
variability on the spatial distribution of D. guineense was evaluated. Modeling techniques of climate envelope based on the
principle of maximum entropy (Maxent) combined with geographic information system were used to predict potential
habitats favorable to the conservation of Dialium guineense. Our results showed that nine categories of uses of the plant can
be noted such as food, medicine, etc. Several diseases were healed by D. guineense (malaria, oral sore, etc). We found a
significant difference between the ethnic groups. The Poisson regression per-formed on the total use value per categories of
use according to ethnicity, gender and age showed that ethnicity and age highly influence usage (P < 0.001). The trading
chain of fruit and leaves of D. guineense had been realized. The average selling price of the measuring tool "togolo" (one
kilogramme) was 250 FCFA ($ US 0.38). Scarification of seeds in-creased the germination rate up to 98%. The density of
coppices of D. guineense had fluc-tuated from 93 to 119 coppices / ha in fallow. Four habitats of the species were identified.
Modeling indicated the guineo-congolese and sudano-guinean zones as very favorable to the conservation of habitats species.
This research suggests the involvement of local populations in decision-making spheres on the use and sustainable
management of plant re-sources. New studies on zoochory and the phytochemistry of leaves have been required for D.
guineense. Actions to promote the planting of the species must focus on the guinean zone and the southern part of the
sudano-guinean zone.

Abstract of Doctorate Thesis
Forest resources of Glazoué -Savè-Ouessè’ districts are under strong anthropogenic pressures. Despite their observed
degradation status, there have long been relics of sacred forests also called sacred woods in regard to their small size. These
are islands of dense dry forest harboring deities.The overall objective of the research is to highlight the importance of the
sacred woods in the conservation of biodiversity in the districts of Glazoué - Savè - Ouessè in Benin.For this work, 59 sacred
woods were surveyed. Flora census was carried out in plots of 30 m x 30 m. Wildlife has been identified inside and around
these relics.The results of the analysis show a floristic species richness of 221 species belonging to 175 genera and 64
families, representing 8 % of Benin flora. As for wildlife diversity, 103 species belonging to 100 genera and 57 families were
identified. Richness and plant diversity are important in the lower strata (< 7 m high), while the upper strata (> 7 m) are
floristically poor and undiversified. Richness and wildlife diversity are closely related to the plant diversity, the higher plant
diversity, the higher wildlife diversity in the sacred woods. Investigations have shown three categories of sacred woods
(voodoo, secret society and cemetery). They provide several services: ecological, religious, ecosystem, ethnobotanical and
ethnozoological. However, despite the influence of human disturbance they are an asset to the conservation of biodiversity.
