Over the last two years keyhole gardens have been promoted in different communities throughout different programmes in African countries. They are popular and productive across vastly different environments and cultures.

Essentially the keyhole gardens consist of a ring of stones (in other countries bamboo or bricks are also used) about 2m in diameter, and about 1m high. At the centre of there is a stick, wire or bamboo structure that contains organic wastes. This is about 1.5 m high, with the soil sloping a pyramid fashion from the edge of retain wall up to the core. Fresh waste and water is poured into this core on a regular. Moisture and nutrients then seep down from this core into the surrounding soil. Access to the core is provided by a small path way, giving the plot an appearance of a keyhole when view from above.
