Regreening dry regions
Tree-farming approach to re-green dry semi-arid areas
Technique used by local farmers for centuries in Burkina Faso.
Mixing trees and food crops leads to increased soil fertility, shielding crops from overwhelming heat and acting as windbreakers.
Technique helps to recharge underground water tables.

Large pits are dug to concentrate rainfall water onto the crop roots.. Main difference is adding manure into the pits during the dry seasons
Dig shallow pits(zai) to concentrate scarce rainfall water.
Add manure to the pit during dry season.
Add tree seeds to the pit.
As the tree seeds sprout with the surrounding crops, e.g. millet, they increase soil fertility.
Leaves that fall to the ground act as mulch and provide fodder for livestock.
