Activation date: 2021-12-01

Event type: Humanitarian

Activation reason:

The scope of the activation is to support the WFP officers with geospatial analysis regarding the agriculture and food security situation and nutrition analysis in 57 AOIs, including the update for 5 AOIs that were already analysed under activation EMSN-063 and EMSN-083, spread between nine Nigerian States: 36 AOIs located at the north-western region (NW) and 21 AOIs at the north-eastern (NE) of Nigeria, near Lake Chad. Due to the inaccessibility of the region caused by on-going armed conflicts, the impact of the conflict needs to be estimated for changes in cropland (loss/gain) and affected population. The analysis was performed in between the reference years of 2010 & 2021, 2017 & 2021, and 2020 & 2021. NDVI composite showing a significant cropland decrease between 2020 & 2021Proposed solution and resultsGeneration of NDVI-composite layers per NW and NE regions for each timestamp of analysisUpdate and verification of the populated sites layer based on freely available imagery and dataCrop change analysis per populated site based on the NDVI-composite layer between 2010 & 2021, 2017 & 2021, and 2020 & 2021Interpolation of the population data per populated sites applying a Thiessen polygon analysisAnalysis of population affected by cropland loss/gainPopulation distribution per populated sitePopulated sites affected by cropland change by timeframe and location
