Recent studies have shown that the cultivation of millet and sorghum in Africa is closely linked to the increasing aridity of the continent. In a new paper published today in Nature, an international team of scientists have demonstrated that the cultivation of millet and sorghum is closely linked to the increasing aridity of the African continent, with the two crops even helping to drive the process.

The research team found that the spread of these two crops was closely linked to the expansion of semi-arid and arid regions around the continent. Millet and sorghum can tolerate drier conditions than other cereals, so their spread was closely associated with the aridification process. The results of the study imply that the cultivation of millet and sorghum could be used as a tool to help mitigate the effects of climate change in Africa.
