The Sahel Was Planting the Wrong Trees for Decades — Here's What Actually Works

For decades, the Sahel was planting the wrong trees and the results were staggering. More than two billion dollars funded large-scale campaigns where eighty percent of the species were fast-growing exotics, yet five years later only about thirty-five percent were still alive.

In this video, you’ll learn why initiatives like the Great Green Wall struggled to deliver lasting impact and why the real fix was not planting more trees, but planting the right ones. We break down survival audits across Burkina Faso, Mali, and Niger, and the evidence showing how fifty-five native species outperform eucalyptus and imported pine models. We explain the biological advantages that matter most in extreme dryness, including roots extending beyond three meters, stronger drought leaf retention, natural pest resistance, and nitrogen fixation that improves soil instead of stripping it.

We also examine the economics. Native species such as baobab, Balanites, and gum acacia can generate up to four times the revenue of earlier plantation approaches, boosting household incomes between nineteen and seventy-eight percent. Finally, we look at how Kew’s Millennium Seed Bank safeguards millions of seeds as long-term insurance for Sahel restoration.
