Most of Africa’s farmers, working tiny plots, do not produce enough food to feed their families, much less to earn an income. The root of the problem is that Africa’s farmers are too poor to obtain the basic modern inputs—including high-yield seed varieties, fertilizers, and small-scale water management systems—that could enable them to double or triple their output of food and cash crops.
想想非洲的饥荒吧。大多数非洲农民在小块土地上耕种，打出的粮食不足以果腹，更别说赚取收入了。问题的根源在于，非洲农民太贫穷，无法获得基本的现代化农用物质—包括高产种子、肥料以及小规模水利管理系统—以便他们能够使粮食和经济作物产量翻一番或两番。
