Abstract:
In southern Africa, land degradation and desertification affect the territory to a considerable extent. Given the lack of economic resources to reverse the problem in many countries within the region, prevention mechanisms can be key to address further land degradation and desertification. The use of Earth Observation Data for analyzing land degradation and desertification dynamics, in southern Africa is widely and consistently used. Under the Desert watch Extension project a consistent methodology to attain an Indicator of Susceptibility to Desertification was developed. In this paper we aim to implement the Indicator for Susceptibility to Desertification through Desert Watch Extension methodology, but employing new Earth Observation Data from the satellite mission of the Project On Board Vegetation-Proba-V. Our preliminary results validated the use of this new Earth Observation data set for the analysis of the spatial variability as well as temporal dynamics of drought, one of the key driving factors of land degradation and desertification in the region.
