New Report: Climate 'could devastate crops'

Climate change could cause severe crop losses in South Asia and southern Africa over the next 20 years, a study in the journal Science says. The findings suggest southern Africa could lose more than 30% of its main crop, maize, by 2030. In South Asia losses of many regional staples, such as rice, millet and maize could top 10%, the report says. The effects in these two regions could be catastrophic without effective measures to adapt to climate change. More here.
