Crop change detection in conflict areas, Nigeria (2020-02-14)

Collection: CEMS-RRM : CEMS Risk and Recovery Mapping 


Activation date: 2020-02-14
Event type: Humanitarian

Activation reason:

EMSN063 was activated to support the World Food Program in order to provide information about cropland change and population affected by cropland loss in the north-eastern Nigerian Borno region over 5 AOIs, helping to understand the food security situation. The area under focus is has not been accessed for several years and little to no data could be collected due to intense fighting activities by Boko Haram since 2010.The aim of the activation is a crop change analysis implemented between the two reference years of <2010 and 2019. The methodology is based on the generation of NDVI-composite layers per time stamp using High Resolution imagery data (Sentinel-2 for 2019, Aster and Landsat for <2010). Crop change is determined per on populated site level, whereas a respective database was created based on open available data. Population data were link to each populated site to determine the affected population by cropland loss.Proposed solution and resultsGeneration of NDVI-composite layers per AOI per timestampCreation of a populated sites layer based on freely available dataCrop change analysis per populated siteImplementation of population data (source: Worldpop) per populated siteMaps showing the crop change per populated siteStatistical analysis wrt population affected by cropland lossSignificant cropland decrease (right) in the region Guzamala By cropland change in conflict areas affected population (2019) in Nigeria
