EMSN-063 assesses changes in cropland in conflict affected areas in Nigeria’sBorno state between 2018/2019 and 2007-2010/2013. To estim ate the im pact ofconflict in these inaccessible areas of Nigeria and to estim ate the populationaffected by cropland loss, a crop change detection was perform ed.The present m ap shows the results of crop change analysis in the LGA ofKala/Balge. The m ethodology is based on a previously by W orld Food P rogram(W FP ) applied study in the Mopti region of Mali.The crop change analysis is based on H R im agery data. The estim ated geom etricaccuracy (R MSE) is 100 m or better, from native positional accuracy of theback ground satellite im age.The estim ated them atic accuracy of this product is 85% or better, as it is based onvisual interpretation of recognizable item s on very high resolution optical im agery.

Map ProductionFor each tim estam p, a NDV I com posite raster layer was created, providing thebase for the crop change analysis. For the determ ination of the crop change, apopulated sites dataset was created based on a com bination of a num ber ofreference ancillary data im proved through visual inspection and m anual editingusing the freely available Google earth im agery. Each of the populated sites wereinspected m anually in order to determ ined the status of crop change, com paringthe NDV I-com posite layers of <2010 and 2018/2019.The m ap shows the used "post-event" satellite im age of 2018 in R GB, clipped tothe AO I-boundary. To provide an overview over all NE Nigeria regions, an ESR Ibasem ap (© Source: Esri, DigitalGlobe, GeoEye, Earthstar Geographics,CNES/Airbus DS, U SDA, U SGS, AeroGR ID, IGN, and the GIS U ser Com m unity)was included as back ground.The basic topographic features such as m ain roads, hydrography and m ainsettlem ents as well as the adm inistrative boundaries shown in the m ap are derivedfrom public datasets.
