Improving the way people manage land could play a bigger role in fighting climate change than previously thought, according to a new study of how greenhouse gas emissions can be reduced and stored in forests, farmland, grasslands and wetlands. …The study, led by scientists from The Nature Conservancy, Colorado State University and 14 other institutions, was published Oct. 16 in Proceedings of the National Academy of Sciences. …The research team identified 20 natural solutions that increase carbon storage and reduce greenhouse gas emissions across forests, wetlands, grasslands and farmlands. Solutions include restocking forests that have been depleted; avoiding the removal of forests for other needs, including agriculture; and using biochar, a charcoal, to help fortify soil. They also assessed the costs of the different options.
