We model future changes in land biogeochemistry and biogeography across East Africa. East Africa is one of few tropical regions where general circulation model (GCM) future climate projections exhibit a robust response of strong future warming and general annual-mean rainfall increases. Eighteen ...

Implications of future climate and atmospheric CO2 content for regional biogeochemistry, biogeography and ecosystem services across East Africa
During the 1990s, a soils database was developed by the International Soil Reference and Information Centre in The Netherlands for the project “World Inventory of Soil Emission Potentials” (WISE). Using this database, we converted 1125 soil profiles from around the world into a format that can be...

Integrated assessment seeks to combine models of the ecological as well as the social system to allow different scenarios to be tested in terms of their likely impacts on ecological functioning and household well-being. We outline such work undertaken in four case studies in East and southern Afr...

Coping strategies in livestock-dependent households in East and southern Africa: a synthesis of four case studies
Agricultural practices have constantly changed in West Africa, and understanding the factors that have driven the changes may help guide strategies to promote sustainable agriculture in the region. To contribute to such efforts, this paper analyzes drivers of change in farming practices in the re...

Markets and climate are driving rapid change in farming practices in Savannah West Africa
Climate change science has been discussed and synthesized by the world's best minds at unprecedented scales. Now that the Kyoto Protocol may become a reality, it is time to be realistic about the likelihood of success of mitigation activities. Pastoral lands in the tropics hold tremendous sequest...

Is it possible to mitigate greenhouse gas emissions in pastoral ecosystems of the tropics?
We describe the development of an open-source mapping and query utility. The impetus for its development came originally from the need to be able to locate, spatially, target populations of resource-poor livestock keepers in the developing world, and to identify livestock management interventions...

GOBLET: an open-source geographic overlaying database and query module for spatial targeting in agricultural systems
In this paper we provide evidence to show that farmers' perspectives on poverty processes and outcomes are critical in the early stages of evaluating impact of agricultural research on poverty. We summarize lessons learned from farmer impact assessment workshops held in five African locations, co...

Assessing research impact on poverty: the importance of farmers’ perspectives
The interest in agricultural soils as global storage of carbon has increased in recent years, along with the prospect of farmers' participation in payment schemes under the Clean Development Mechanism of the Kyoto protocol. Thus, a better understanding of agricultural practices that can increase ...

Carbon sequestration and farm income in West Africa: Identifying best management practices for smallholder agricultural systems in northern Ghana
Sub-Saharan Africa faces huge food supply challenges due to increasing human population, limited opportunities to increase arable land, and declining yields associated with continuously declining soil fertility. To cater for their food requirements, smallholders use only modest levels of inorgani...
