"Although Big Ag, many NGOs and other groups (e.g., the Gates Foundation and segments of the U.S. government) continually stress that the top three solutions to Africa's hunger problem are 1) more yield, 2) more yield, and 3) more yield (with additional U.S. food aid running a close fourth), Africa’s farmers have a lot more to worry about than yield. . . Designing and building appropriate technology – where the users’ many needs are taken into account before design begins – isn’t going to do much for corporate bottom lines, but elegant designs like the bicycle-powered grain mill might be a better place to direct development aid, instead of on GMOs and other projects that do more for corporate profits than for Africa."
