Eastern Cape Province in South Africa has experienced extreme drought events during the last decade. In Africa, different land management systems exist belonging to two tenure classes: commercial large scale farming and communal small-scale subsistence farming. Communal lands are often reported be affected by degradation among others considered as trigger for this process. Against background, we analyzed vegetation response through assessing productivity trends monitoring intensity,...
