Africa’s “$50 Billion” Desert Wall Isn’t What You Think

A wall of trees stretching across Africa sounds like the perfect answer to the Sahara. But the real Great Green Wall is far more surprising — and much harder to measure. On CORA ELSEWHERE, we follow the story from the original continental vision to small planting pits, living roots and the communities deciding what restoration should actually mean. Why do published totals disagree? Where does the $50 billion headline come from? And can a project succeed by becoming less like a wall? The "$50 billion" figure is a headline framing, not one fixed construction budget. Funding estimates, pledges, money delivered and land restored are different things. The 2030 figures discussed are targets, not completed results.
