Summary for Project title: R7446: Shortened bush-fallow rotations for sustainable livelihoods in Ghana.

A participatory process in Ghana is developing technologies with key input from end users. Participatory technology development (PTD) is helping to convert current land use—based on growing crops in rotation with bush-fallow—into more productive systems. The PTD method incorporates farmers' local ecological knowledge about fallows into designs that fit in with local tenure rules and farming practices. It's also behind two pilot decision-support tools. These garner locally appropriate information, to improve the way fallows are managed in West and Central Africa, and to produce custom extension materials that aim to boost yields in cocoa-based farming systems. The PTD method is currently being used in Ghana, while the decision-support tools (that are available from several websites) are used internationally, including in the West Indies, Venezuela and Mali.
