THe Great Green Wall being built in Africa to halt the southern progress of the Sahara Desert is a favorite public works project

THe Great Green Wall being built in Africa to halt the southern progress of the Sahara Desert is a favorite public works project of mine — it’s massive, ambitious, long-term, important, and if it works, the effect will repay the cost many times over. This video takes a quick look at some of the work being done on the wall in Senegal.

    I have watched some videos on it, very cool. That said, I pretty sure those photos in the comparison are taken at different times of year?

      It is explicilty mentioned at the beginning of the video, that the country is as green as it gets, since it is the end of the rainy season.

      All the area that is filled with the half moon structures would be barren during rainy season too, as you can see with the soil around the half moons. It will look less impressive at the driest time of the year, but the positive effects of retaining biomass and water will remain present.

        I was talking about the comparison image that appears in the post (pulled from the article)
