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 …

An analysis of the investment portfolios of 12 wealthy pastoralists who live on the Borana Plateau of southern Ethiopia was performed based on their responses provided during face-to-face interviews held during January-February 2015. The survey respondents were found to invest primarily in livestock (about 65% of the average portfolio was livestock) but also had significant non-livestock investments. Risk reducing investments appeared to take the form of buying more camels and fewer cattle or investing in real estate or bank accounts. Cattle offer the highest average return of the assets considered but are also relatively risky due to die off during …

Boran pastoralists say they have one over-riding problem: Limited drinking water for both people and livestock. Ponds are therefore a critical resource. However, lack of livestock control in pond catchments subjects them to heavy grazing and trampling that creates landscapes vulnerable to erosion. Ponds collect sediment after rainfall events and water holding capacity is reduced We wanted to test a system to improve the managements of pond catchments. In March 2014 we erected bush fences to enclose catchments surrounding on demonstration pond in each of four Pastoral Associations. The purpose was to prevent unregulated livestock access and allow recovery of …
