An agriculture engineer/scientist/policy maker should need $25 and 1 acre of land to demonstrate how a poor family in an under developed country could earn $5000/year as well as provide food security for his family These are the resources many poor families may have available.. Dr. Booker T Whatley (Tuskegee University) showed how US farmers could earn more money with a relatively small amount of land in his 1987 book "How to Make $100,000 Farming 25 Acres". Many US farmers use his ideas.
