Scientists estimate that peatlands around the world hold about 350 billion tonnes of carbon. The tropical peatland of the Congo Basin – known as Cuvette Centrale - are thought to store the equivalent of 20 years of US fossil fuels emissions. BBC Africa Correspondent Andrew Harding has been up to his neck in it, witnessing the work being done by scientists to protect it and what might threaten its future. He also hears a warning from Environment Minister, Arlette Soudan-Nonault, about the choices the Republic of Congo faces between preserving the peatlands and making use of its resources to provide a living for its population. We find out how one simple lesson learned in Indonesia is being shared with countries in Africa and South America to help keep a global promise to protect tropical peatlands. It’s not just about promises though – financial experts explain why persuading richer countries to pay cash for “wasteland” could be good for all of us. Presenters Kate Lamble and Neal Razzell are joined by: Dr Daniel Murdiyarso, Principal Scientist with the Centre for International Forestry Research, Indonesia Prof Kevin Chika Urama, Chief Economist, African Development Bank Sara Jane Ahmed, finance advisor to the V20 Group of climate vulnerable countries.
