Keyhole Gardens are a type of garden bed that allows food to be grown into the dry season (in African countries) and in dry climates. The plants/beds are fed/watered through a central basket which contains compost, manure, woodash, kitchen scaps etc and grey water. They survive floods as they are raised off the ground and work good in very hot weather as they retain moisture well.
If you like you can donate a “Keyhole Garden” which will basically help train more people in how to make them over in Africa: http://www.sendacowgifts.org.uk/build-a-keyhole-garden
Check out this fascinating and informative publication (linked below) on Desertification and Land Degradation and its effect on food security and regional conflict.
“A new publication by the UNCCD examines desertification as a cause of global conflict and instability and calls for urgent action to support communities in crisis.
More than 1.5 billion people in the world depend on degrading land, and 74% of them are poor. As the effects of climate change undermine livelihoods, inter-ethnic clashes are breaking out within and across states and fragile states are turning to militarization to control the situation.
The effects of desertification are increasingly felt globally as victims turn into refugees, internally displaced people and forced migrants or they turn to radicalization, extremism or resource-driven wars for survival.
If we are to restore peace, security and international stability in a context where changing weather events are threatening the livelihoods of more and more people, survival options are declining and state capacities are overburdened, then more should be done to combat desertification, reverse land degradation and mitigate the effects of drought.
Otherwise, many small-scale farmers and poor, land-dependent communities face two choices: fight or flight.”
