Using an integrated approach to water, nutrient and crop management, this research project optimized the use of inputs and improved crop production in semi-arid areas in the Volta basin, where rain-fed agriculture is often considered a risky venture. Working with communities in Burkina Faso and Ghana, the project demonstrated that crop yields can be increased several-fold through the introduction of simple, low-cost technologies and the inclusion of legumes in the crop rotation systems.
In order to help farmers capitalize on their increased crop yields, the project introduced an inventory credit system which has led to increased household food security and financial stability for farmers. Key to the long-term success of this project were the farmers’ associations and community based organizations that worked as partners with researchers.
