Pedro A. Sanchez, director of the Tropical Agriculture and the Rural Environment Program at Columbia University's Earth Institute, has come a long way from the Cuban farm on which he was born. In 2002 he won the World Food Prize for, among other things, helping Brazilians turn 70 million acres of infertile savanna into productive farmland. Sanchez later led a project in Peru that dramatically increased rice yields and headed a center in Kenya that upgrades soil, and thus expands food production, by planting nitrogen-fixing trees in crop fields. Currently Sanchez, who earned degrees in agronomy and soil science at Cornell University, is director of the Earth Institute-sponsored Millennium Villages, model African communities that use high-yield seeds, fertilizers, medicines, drinking wells, and even the Internet to lift themselves out of poverty. Our reporter caught up with Sanchez while he was in Timbuktu, Mali, visiting one of those villages.

Sanchez）与他出生的古巴农场相距甚远。 2002年，他因帮助巴西人将7000万英亩的不育大草原转变为生产性农田而赢得了世界粮食奖。桑切斯后来在秘鲁领导了一个项目，该项目大大提高了稻谷的产量，并领导了肯尼亚的一个中心，该中心通过在田间种植固氮树来改良土壤，从而扩大粮食产量。目前，桑切斯（Sanchez）在康奈尔大学（Cornell University）获得农学和土壤科学学位，目前是地球研究所资助的千禧村（Millage Village）的负责人，这些村庄利用高产种子，化肥，药品，饮水井，甚至通过互联网来提升自身实力，成为非洲社区的榜样摆脱贫困。我们的记者在马里廷巴克图访问桑切斯时访问了其中的一个村庄。
