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.

Musk dreams of terraforming Mars. Real heros are the one who can terraform Sahara.

@FrancoisPrague I am not convinced extracting water that took hundreds of thousands of years to accumulate, and use up in a few decades is a sustainable or fair to future generations. Maybe if it could be managed as a commons in a wise way, planting trees and maybe some climate specific agriculture.

@dacig I think the same. Groundwater is one of the most important treasures for our future - and we see a lot of new desertification where people take too much of it, in countries that never had deserts.

@NatureMC @FrancoisPrague That happens back in Mexico where I'm from.
Pozos Profundos, deep wells, seem like a good idea at first, making agriculture possible where the sun is plentiful, but they will dry up rather quickly.
Extractivism is not the way forward. Shepherding resources is.

The only difference I spot is that the Sahel is not part of it any more, just Kenya, Tanzania and Senegal. The half moon technique I have already seen in various films on the Great Green Wall.

Don't get me wrong, I'm not making any critique of the new project, just trying to understand its relation to the one I already knew about. The absence of Sahel in particular is regrettable but quite understandable:

Was also my first thought. It's always important to check independent sources. Would be interesting to find scientific studies about what really works and what is only a campaign.
A good article - thank you!

@ducasleo I also thought it was part of it. The half moon digging being the method used for the Great Green Wall Project and everybody kinda joining into this one big effort with smaller task forces.

We've tried this technique in Brandenburg, Germany at #ArschDerHeide on our very poor dry sandy soils. Even there you can see its impact. It is not just the water soaking in. It is also the small wind break and shade that helps young plants to sprout & establish in the semi circles.

I half-remember some doco I saw through permaculture networks, in which a similar technique was used in the US to rehabilitate land that was part of the Dust Bowl.
