As part of the FAO (Food and Agricultural Organization of the United Nations) project Land Degradation Assessments in Drylands (2006– 2010), it is intended to gain new insights into the spatial distribution and intensity of soil degradation as well as to investigate connections between degradation and agriculture, population pressures and poverty. To identify degraded soil, satellite recordings between 1981 and 2003 were analyzed for changes in vegetation in a study by Bai et al. Although the methodological approach to identifying soil degradation is fraught with a certain amount of uncertainty, researchers were able to identify regional hotspots of degradation, which provided grounds to carry out more in-depth and on-site investigations.
