CGIAR Climate's insight:

The global population is estimated to rise to 9.2 billion in 2050, and to feed us all, it has been calculated that we will need 70% more food production. The need to find more sustainable sources of food has led governments and intergovernmental groups such as the World Bank, the Food and Agriculture Organisation of the UN and even the Intergovernmental Panel on Climate Change to look for supplementary, and alternative, regions to grow crops, both for food and biofuels. One type of habitat that is getting a lot of focus, and is assumed to be suitable is wet savannah, particularly those in Africa. But these habitats, with their sufficient rainfall and lack of dense cover, argues Tim Searchinger in Nature Climate Change this week, are not a low environmental cost solution for converting to cropland. Based on new studies, he estimates only 2% of these areas would be suitable for growing maize with carbon levels less than the average and that the threat to biodiversity is another reason for the world’s leaders to seek alternative sources of food.
