The economic benefits of transforming global agricultural and food systems towards greater climate and biodiversity conservation could reach between five and ten trillion US dollars per year by 2050. The costs, on the other hand, would only be between 200 and 500 billion US dollars per year. This is the conclusion of a study by the Food System Economics Commission (FSEC). The commission includes institutions such as the Potsdam Institute for Climate Impact Research, the World Bank and the World Health Organization. The study took four years to complete.
