This study of the evolution of AWM in the Volta Basin yielded key recommendations for research-for-development interventions and new concepts for research on water management. When promoting AWM strategies, projects should carefully study the available information on factors triggering adoption,

and play on these to ensure sustainable uptake of the technology. Local capacities and agendas should be better accounted for when promoting AWM strategies or low-cost irrigation technologies. Participatory

In the northern highlands of Ethiopia, establishment of exclosures to restore degraded communal grazing lands has been practiced for the past three decades. However, empirical data on the effectiveness of exclosures in restoring degraded soils are lacking. We investigated the influence of exclosure age on degree of restoration of degraded soil and identified easily measurable biophysical and management-related factors that can be used to predict soil nutrient restoration.

Extent and implications of incorrect offspring-sire relationships in pastoral production system in Kajiado District, Kenya

Journal Articles & Books
Dezembro, 2008

The aim of this study was to evaluate accuracy of farmer's paternity identification which determines success of future breed selection and hence genetic gain. Paternity of 269 Orma/zebu and Sahiwal/zebu calves was evaluated using genetic markers and the likelihood based method. Results indicate that only 6.7% farmer alleged paternities were confirmed, 88% parent-offspring relationships were rejected and 18% parent-offspring relationships were undetermined. However, 82% of offsprings were assigned at least 80% confident paternities to one of the sampled candidate males.

Waterlogged Vertisols are amongst the high potential soils where management interventions could result in positive impacts. This study utilized soil, climate and crop and livestock productivity data and models to demonstrate intensification strategies which increase crop–livestock system productivity and to understand the effects of alternative land use and water management options on water productivity in the Vertisols areas.

Using the farm as unit of analysis, diagnosis processes aimed at improving production systems are reviewed. Within a country, diagnosis should be conducted at different hierarchical levels: local (interaction between the production system and the input distribution sector, the marketing sector, possible forms of processing, and consumption characteristics); regional (appropriate selection of target site); and national (development trends and governmental policies at the macroeconomic and sectorial levels).
