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.

The half-circles are called zaï! They’re a traditional farming practice in the Sahel desert, and their introduction + reintroduction can be largely credited to Yacouba Sawadogo, the man linked above! He reintroduced and innovated on the zaï on his own farm in the 1980s, and did extensive outreach (along with scientist Mathieu Ouédraogo) to encourage other farmers to adopt them as well.

He also promoted the use of cordons pierreux, which are basically just lines of rocks to reduce erosion, preserve sediments, and increase water absorption.

Immensely cool dude. He’s been a personal hero since I learned about him.
