Keyhole Gardening was introduced in Africa by the Consortium for Southern Africa Food Security Emergency (C-SAFE) to help ailing and frail Africans grow their own produce with minimum effort by means of a specialized raised bed. The bed, which is waist high and in the shape of a keyhole, allows for standing and leaning for long periods and is built using stacked rocks, bricks, wood or pieces of concrete.
