Effects of region-wide soil and water conservation in semi-arid areas : the case of northern Ethiopia

Abstract

This study makes a multi-scale assessment over a time span of 30 years of environmental rehabilitation in one of the world's most degraded areas : the Tigray highlands. It study shows that in Tigray sheet and rill erosion rates have decreased by approximately 68%, infiltration and spring discharge are enhanced and vegetation cover has improved. These impacts are evidenced and quantified by a comparison of the current landscape with a coverage of 30-year old photographs and substantiated by field investigations. The positive changes in ecosystem service supply that result from these conservation activities in the Tigray highlands are an issue of global concern
