1. Drip irrigation places water just at the root zone,reducing evaporation of precious water. Thissystem is located in the Negev Desert in Israel.
2. A bag of water is collected by using this pump. Itis a part of a qanat—a system of undergroundbrick-lined tunnels and wells that collect runoffwater from the mountains.
3. This irrigation canal in Oman has delivered waterfor over a thousand years. The canals are carefullymaintained to provide water for agriculture.
4. A noria—or waterwheel run by the flow of water orby animal power—is used to lift water from the riverto the fields. These two are located in Syria on theOrontes River.
