A recent report by the climate change Agriculture and Food Security (CCAFS) research group says global warming will cause famine in South Asia and sub-Saharan Africa. CCAFS researchers focused their observations on the tropics and identified the regions with chronically-malnourished populations who are highly dependent on local food supplies. As many African areas are expected to become drier, countries such as South Africa whose agriculture is mainly based on maize farming can shift to more drought resistant crops. Countries such as Niger, however, will not have many options because they are already supporting themselves by very drought resistant crop varieties, such as sorghum and millet. Read more here.
