In 2011, the Horn of Africa faced the worst drought in 60 years, leading to emergency food insecurity levels in Kenya and Ethiopia and famine in Somalia.

Attention to land degradation and environmental pollution has increased significantly in the past 25 years, largely due to greater levels of international cooperation and recognition that local changes in land resources have global impacts.

In recent years, prices of agricultural land have increased quickly, actually doubling and tripling in many parts of the world. This land value reassessment has been prompted by rising crop prices and perceived land scarcity.

"This article analyzes the on-site and off-site economic impacts of various sustainable land management (SLM) practices in Kenya. Long-term trial data are used to establish the relationship between SLM practices and maize yield.

Western Kenya is one of the most densely populated areas in Africa. Farming there is characterized by low inputs and low crop productivity. Poverty is rampant in the region. Yet the potential for agriculture is considered good.

This case study explores the development, dissemination, adoption, and impact of improved tree fallows in rural western Kenya. The processes of technology development and dissemination throughout the region are described and analyzed.

This case study explores the relationships between agroforestry-based soil fertility replenishment (SFR) systems (improved follows and biomass transfer) and poverty reduction in rural western Kenya.

As the goals of international agricultural research move beyond increasing food production to the broader aims of reducing poverty, both agricultural research and studies of its impact become more complex.
