Once so barren it could barely support the towns of Al'Isawiyah and Tubarjal (upper left of each image), a vast desert region gradually blossomed into crop-producing fields (green dots) by use of center-pivot irrigation. The system used here draws from an ancient aquifer containing water as much as 20,000 years old. Judicious use of water resources and climate-appropriate technology has improved food production without harming the environment. Image by Landsat.
