Abstract

This paper analyses the factors that control rates and extent of soil erosion processes in the May Zegzeg catchment near Hagere Selam in the Tigray Highlands. Soil loss rates due to various erosion processes, as well as sediment yield rates and rates of sediment deposition within the catchment (essentially induced by recent soil conservation activities), were measured using a range of geomorphological methods. Soil loss rates by water (gully erosion) are important and also tillage erosion and rock fragment displacement by gravity and livestock trampling. Through targeted interventions, rural society is now well on the way to control and reverse the degradation processes
