Howard Buffett’s foundation has created a 1,400 acre experimental farm in Arizona to simulate conditions in Africa to create new theories and test new farming techniques. The foundation does work to find solutions for food and agricultural issues in 78 countries around the world, 41 one of them in Africa. The property allows the foundation to experiment with developing new systems that can be applied in subsistence farming countries, such as planting seeds at the same time the land is being plowed by oxen.
