East Africa: Climate cropland changes 'raising temperatures'

Research predicts that vast amounts of land in East Africa will be converted from grasslands to ploughed fields over the next 40 years, as wetter conditions caused by climate change attract crop farmers to grazing grounds. "The transformation of natural ecosystems into croplands will be the biggest contributor to global warming in East Africa," says Pius Yanda, director of the Institute of Resource Assessment at Dar es Salaam University in Tanzania.
