In Ethiopia’s lowlands, climate change, erosion and drought degrade land, cut yields and fuel conflicts among agro-pastoralists. The Dry Valley Rehabilitation and Productive Use approach under the global GIZ ProSoil programme integrates technical and socio-ecological measures to restore dry valleys, secure water and promote sustainable land use. The approach uses Water Spreading Weirs, Dry-Stone Measures and biological measures. Water Spreading Weirs span dry riverbeds to spread and slow floods, enhance infiltration, trap nutrient-rich sediments and improve soils and vegetation. Based on a traditional and administrative system, the approach follows 7 steps from satellite-based suitability mapping to participatory planning by user cooperatives, rehabilitation and productive use. GIZ, BMZ, Ethiopian agencies, research bodies and communities collaborated to build 110 Water Spreading Weirs and 205 Dry-Stone Measures in Afar with similar work in Somali and Oromia, restoring 55,500 ha of degraded land and supporting 6,000 people.
