Tree-planting schemes don’t always work, so what’s the best way to do forest restoration? Projects around the world are planting huge numbers of trees as part of the fight against climate change. But not all of these schemes are successful – leaving dead saplings and wasted money in their wake. People Fixing the World works out how to do it right. In West Africa, we look at how farmers have reforested and restored huge areas without planting a single seed. In Brazil, we visit a project that has planted more than 600,000 trees in the endangered Atlantic Forest. Myra Anubi also hears about new satellite technology which can help us map reforestation across the world, to give a clearer picture of what is and isn’t working when it comes to growing trees.
