Agricultural intensification in West Africa is in its early stages and several hypotheses have been postulated about its evolution and possible pathways. In addition, farm efficiency may vary across farms and other socio-economic domains, opening opportunities to improve efficiency and...

Considering leguminous trees Leucauena and Gliricidia as good sources of quality food, on-station and on-farm studies were conducted in the humid zone of West Africa to establish animal responses to levels, times and forms of browse supplementation, to develop alternative feeding strategies for...

Farmer participatory tillage trials were conducted in a highland Vertisol area of Ethiopia during the 1999 and 2000 cropping seasons. This participatory initiative clearly demonstrated that incorporating farmers’ knowledge, ideas and preferences could improve the wheat production package. A...

Agricultural intensification in West Africa is at an early stage and the process is taking place through various pathways. Population pressure and market access are generally considered as major factors driving intensification and crop-livestock interaction. In this paper both ecology and...

A dynamic bio-economic model is used to show that, without technological and policy intervention, soil nutrient balances, income and nutrition could not be substantially or sustainably improved in a highland area of Ethiopia. Although cash incomes could rise from a very low base by more than 50%...

This paper presents a conceptual framework for water accounting and provides generic terminologies and procedures to describe the status of water resource use and consequences of water resources related actions. The framework applies to water resource use at three levels of analysis: a use level...
