Crop change detection in conflict-affected areas of Nigeria, agricultural season 2022 (2022-09-28)

Description

Activation date: 2022-09-28
Event type: Other

Activation reason:

The scope of this activation is to continue and update the analysis already performed under CEMS-FLEX activations EMSN063, EMSN083 and EMSN113, providing information about the agriculture, food security and nutrition analysis situation in Northern Nigeria, in support of the WFP officers. For the 4th edition, it was required to analyse 44 AOIs (33 to be updated and 11 newly analysed) distributed between four Nigerian States: 35 AOIs located at the north-western region and 9 AOIs at the north-eastern, 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 & 2022, 2017 & 2022, and 2021 & 2022. Proposed 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 ancillary dataCrop change analysis per populated site based on the NDVI-composite layer between 2010 & 2022, 2017 & 2022, and 2021 & 2022Interpolation of the population data per populated sites applying a Thiessen polygon analysisAnalysis of population affected by cropland loss/gain
