It’s crazy that countries on the edge of the Sahara desert are reversing desertification by just digging half circles
The ground in these places is too compact for water to soak in during wet season which leads to flooding but digging these holes gives the water a place to stop and soak in. And they’re pushing back the desert with this. By just digging holes.
The new plants also help even more water soak into the ground which reduces flooding even more.
These places also give people places to grow food and graze animals like people are turning completely dry compact desert into a refuge for wildlife and plants and solving regional food insecurity just by digging holes.
