Centuries-old African soil technique could combat climate change - scientists

By Kieran Guilbert DAKAR (Thomson Reuters Foundation) - A farming technique practised for centuries in West Africa, which transforms nutrient-poor rainforest soil into fertile farmland, could combat climate change and revolutionise farming across the continent, researchers said on Tuesday. 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 atmosphere, according to a study carried out by the
