A farming technique practised for centuries in West Africa, which transforms nutrient-poor rainforest soil into fertile farmland, could combat climate change and revolutionize farming across the continent, researchers say. Adding kitchen waste and charcoal to tropical soil can turn it into fertile, black soil which traps carbon and reduces emissions of greenhouse gases into the
