A Plan to Slow the Creep of the Sahara—by Planting Gardens | WIRED (Me: Wisdom!)

Aly Ndiaye, a Senegal-born agricultural engineer who helped design the tolou keur, told Reuters that the Great Green Wall ought to be made up of smaller, productive gardens that are “permanent, useful, and sequential,” a series of practical plots rather than an unbroken line of trees. Okolie agrees that the project can’t be about shoving any seedling in the ground. He says it must entail “trying to locate the best species that can thrive” in the given soil conditions and climate, while also appealing to the people who will nourish them. Researchers have found that agroforestry projects often fail when the focus is solely on tree-planting and locals are left out of the process. “When the government plants trees, it’s the community people who will sustain them” Okolie says. “The community has to take ownership.”
