摘要

By African standards, Rwanda is an agricultural success story. Yields of bananas, beans, cassava and maize—the four main crops by land area—have all risen substantially since the turn of the century. Over the five years to 2017, the country's maize fields were more productive than those in neighbouring Burundi, Kenya or Tanzania, according to the Food and Agriculture Organisation, an arm of the UN.
