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.

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

No terraforming is necessary in Sahara, just accessing the water underneath.

@appassionato @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 @appassionato @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.

Which means banning fracking.
