• Resumen

  • Focuses on the design of irrigation and water conservation systems by Jack Keller, the founder and chief executive officer of Keller-Bliesner Enterprises in Logan, Utah, and a member of the board of directors of International Development Enterprises, Lakewood, Colo. Crops will not grow without water, and small farms in developing countries cannot afford the costly, complex irrigation systems used by larger operations. International Development Enterprises, a nonprofit organization dedicated to helping small landowners increase agricultural productivity, began field-testing affordable new sprinkler and water storage systems designed by Jack Keller earlier this year. Keller's innovative water storage tanks hold 10,000 liters and cost just $40, and his drip irrigation and micro sprinkler systems provide hydration for as little as five cents per square meter.
