African farm yields are increasing, thanks to improved technology, such as better-fertilised hybrid seeds. Better governance is also playing an important part. For example, Rwanda and Ethiopia have tripled grain (Rwanda) and cereal output (Ethiopia) from 2004 to 2014. Technology such as mobile phone subscription services can provide farmers with better price data and increase profits. Better information on potential storage facilities, closer to the farm, will also improve profits and reduce waste. However, poor infrastructure (distance and roads conditions), limited irrigation and high tariff barriers still curtail prices and exports.
