Gully formation and upland erosion were studied in the Debre-Mewi Watershed in the Gilgil Abay Basin south of Lake Tana. Gully erosion rates were found to be equivalent to over 500 tonnes/ha/year for the 2008 rainy season when averaged over the contributing watershed. Upland erosion rates were tw...

Considerable research has been conducted into the technical adaptation measures that Ethiopian farmers might adopt to mitigate adverse climate change impacts. However, relatively little is known about Ethiopian farmers? perceptions of using water storage and land allocation to combat climate chan...

Identifying efficient water storage schemes for climate change adaptation in agriculture: evidences from Indris Watershed in Ethiopia
The development of water storage schemes in Sub-Saharan Africa is considered a major aid for agricultural regions with scarce water and anticipated climate change impacts. The selection of storage options is often conducted through monetary assessment of direct costs and benefits. Such an approac...

This paper addresses the need for agricultural water storage in developing countries. Rainfall variability is an important factor in development and translates directly into a need for water storage. In many places rainfall variability is likely to be amplified (even where the total amount of rai...

The Usangu wetlands, containing the Ihefu swamp, are one of the most valuable inland wetlands in Tanzania. Over the last decade, outflow from the swamp has ceased for extended periods in the dry season. This has had severe consequences for downstream ecosystems, including the Ruaha National Park....

The SWAT (Soil and Water Assessment Tool) was used to evaluate the impacts of a climate scenario based on IPCC A1B emissions on flows in the Volta River basin in West Africa for 2021-2050 and 2071-2100, using 1983-2012 as the reference period. Overall, the simulation indicates increased variabili...

Water storage can help to safeguard livelihoods and reduce rural poverty. However, ill-conceived water storage will fail to deliver intended benefits and, in some cases, may worsen the negative impacts of climate change. More systematic planning is required to ensure suitable storage systems that...

West and East Africa experience high variability of rainfall that is expected to increase with climate change. This results in uctuations in water availability for food production and other socioeconomic activities. Water harvesting and storage can mitigate the adverse effects of rainfall variabi...
