Trees in drylands can be planted in small depressions called net-and-pan. The basins are then connected by a network of shallow trenches. The trench network collects rain and runoff water falling over a large area and delivers it to the base of the trees. Mulch also collects in the basins, building soil. #livingecology #permacultureinternship
