摘要：Monitoring the environment is a key task of remote sensing in particular in areas whose access is difficult or dangerous or where dense cloud cover obscures optical information. This study proposes an assessment of landscape changes related to large refugee camps, where information about environmental conditions is needed by both humanitarian organizations and regional administrations. Our intention is to provide a robust workflow which is applicable for an operational use. The study area is located in Western Kenya hosts a total number of 350.000 people. Images of ERS-2 and Sentinel-1 are used for the assessment of land degradation in a semi-arid savannah between 1997 and 2014.
