Abstract: Studies on the impacts of environmental rehabilitation in semi-arid areas are often
conducted over limited space and time scales, and do typically not include detailed biophysical
components. 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 of
Northern Ethiopia. The 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 comprehensive 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.
