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 bio-physical components.
As a first in its kind, 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, infiltration and spring discharge are enhanced, vegetation cover and crop production
have 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 changing land
cover and management in the Tigray highlands are an issue of global concern.
This issue of the Tigray Livelihood Paper series contains the whole set of time-lapsed photographs
that were used in the study.
