reforestation in the Sahara

A place to discuss and learn about the restoration of disturbed lands to desirable end land uses
Kinda downplays that it's reforested because they drilled a well and it's irrigated. Act like that mounds fix everything.
Not everything is irrigated. They showed areas that are only fed by rainwater.
I think the point is that the soil was swept away and the ground is impermeable so any rainwater flows into the river or evaporates rather than supporting plant life or replenishing the groundwater.
