Gully erosion is a widespread problem in the Borana plateau. Gullies are the main pathway for sediment accumulation in community ponds, especially during heavy rains, which reduces pond capacity. Sediment movement in gullies can be substantially reduced by installation of sieve structures that slow down water flows and allow sediment to settle out of suspension. Sieves can be easily constructed from trees by community labour at low cost. The community should develop a landscape-level plan and follow a suitable sieve design. Project Kalo collaborators have demonstrated that a series of sieve structures down a secondary gully in the Dikale pond …

The Borana Plateau is an important rangeland for Ethiopia. Livestock production has supported pastoralists here for many generations, and animals are now supplied to a variety of domestic and export markets. The aim of this Livestock Innovation Lab project is to find ways to improve the sustainable productivity of the pastoral system. This is a big challenge, as the rangelands have been badly degraded by decades of heavy pressure from growing human and livestock populations. As a result, there has been extensive bush encroachment on the grasslands and a recent acceleration of gully erosion. The research team used Participatory Rural …

Achieving Development Impact Among Pastoral And Agro-Pastoral People: Lessons Learned In Southern Ethiopia, 2000-2009, D. Layne Coppock, Seyoum Tezera, Solomon Desta, Getachew Gebru

Environment and Society Faculty Publications

The outreach and action-research component of the Pastoral Risk Management (PARIMA) project began with a focus on the Borana Plateau of southern Ethiopia in 2000. Our goal was to use participatory methods to learn about development needs and apply the knowledge gained to benefit local communities. Today it is clear that the project has had positive impacts on the lives of thousands of people. This report helps tell this story by emphasizing the process we used.

At the start we knew that the traditional pastoral system was under intense pressure as poverty and hunger were common. Community-based problem diagnosis confirmed …
