Something to think about for me as I plan next years gardens

Keyhole gardening is considered an “African survival strategy” in a land of scarce resources and unforgiving climate. According to reports from the BBC, 3 keyhole gardens can feed an African family of 10 for an entire year.
A humanitarian aid organization in southern Africa developed this particular sustainable gardening method. The design originates in permaculture which is a branch of ecological design & engineering that develops sustainable human settlements & self-maintained agricultural systems modeled from natural ecosystems.
A keyhole garden is the “ultimate raised-bed planter.” It consists of a circular shape w/ a 6 foot diameter & stands about waist-high. A notched-in section like a pie-shaped wedge allows access to the plants. It can be constructed from local recycled materials & incorporates a central composting basket into which food scraps/organic wastes are placed. The garden is also watered through this basket. It uses far less water than conventional gardens & recycles as it grows. From a birds-eye view this garden reminds one of a keyhole.
