Ali Ouedraogo, 79, sits under a tree on his land, near the north-eastern town of Gourcy. Climate change is making the dry conditions more extreme. He says the trees started dying about 25 years ago, but that none have died since he built rock belts on his land. 'Since I surrounded my land with rock belts I can keep a lot of water in my farm. Consequently, no tree died since that time,' he says.
