We could turn the major deserts into forests if we wanted to. Geoff Lawton did this in the lowest, saltiest place in the Dead Sea, on 10 acres, with nothing but passive water harvesting earthworks, and selective planting. Now, that 10 acres is completely green, and produces enough food for quite a few families, and neighbors. Imagine the rainforest, and 90% of it being edible. Seasonal and successional plantings, so when you walk through it, you can't help but stepping on food. Cassava, Potato, etc, all underneath the ground where you can't see as well.
