Landscape change in arid and semi-arid rangeland of Borana, southerr Ethiopia: implication for management

摘要

The Borana rangelands in southern Ethiopia (between 4°3'Nto 5°0'N and 37°4'E to 38°2'E) comprise important cultural landscapes with a unique feature of the tula-we landscapes. Until a few decades ago, the Borana rangelands were considered one ofthe most productive and resilient ecosystems in East Africa. In recent years, however, the Borana rangelands have undergone a large reduction in grassland cover probably as a result of anthropogenic and natural-induced factors (Coppock 1994), with consequences on the livelihood of the local communities. Therefore, the objective of the study was to investigate the dynamics of landscape change in the Borana rangelands of Ethiopia based on satellites imagery.
