Improved Agricultural Water Management In the Nile Basin

Nile Basin Wetlands: An important natural resourceLisa‐Maria Rebelo 1

1 International Water Management Institute, Addis Ababa, Ethiopia

Wetlands occur extensively across the Nile BasinShould be considered a key component in IWRM

The Sudd Wetland: Mapping inundation extent using ALOS PALSAR

All images provided courtesy of JAXA, and acquired as part of the ALOS Kyoto and Carbon Initiative for Science Team product development: Prototype area, the Upper Nile

Ecosystem services provided by or derived from wetlands (adapted from MEA, 2005)

Water storage

Surface water holding

Groundwater recharge

Groundwater discharge

Flow regulation 

Flood mitigation 

Water quality control

Water purification

Retention of nutrients

Retention of sediments

Retention of pollutants

Hydrological regulating functions of wetlands (Ramsar, 1999)Spatial distribution and areal extent of wetlands within the Nile Basin  (Derived 

from Lehner and Döll, 2004, and Di Gregorio, 2002)

Wetlands offer many important ecosystem servicesThey support a wide range of agricultural activities Their sustainable management is thus critical

Opportunities and constraints for optimal benefits

Knowledge base of wetland

needs

Analyse Sudd hydrology and implications to/from 

WR developments

Knowledge base of socio‐economic system

Analyse opportunities and constraints for optimal 

benefits

Synthesize the 5 components to identify management options, and conflicts and 

tradeoffs for thesePrincipal Components Analysis showing temporal variance, i.e. how 

and when the water moves through the system
