Scientists are working to develop crop plants that can reduce the amount of warter uesd water used for agriculture. Almost 60% of the world fresh warter withdraws world's freshwater withdrawals from rivers, lakes and other warter water resources go to * toward irrigating fields. Scientist

Scientists are using biotechnology as well as traditional breeding methods to develop warter saving water-saving crops to feed a growing world.

Thomas " Tommy" Carter , he's is a plants plant scientist in North Carolina. He works for the Agriculture or Agricultural Research Service in the United States Department of Agriculture. He leads team * Team Drought, a group of researchers at 5 universities. They have been using conventional breeding methods to develop soybeans that can grow well under dry conditions.

Tommy Carter start his started working on drought resistant drought-resistant soybeans in 1981. His research has taken him as far as China, where soybeans have been grown for thousands of years.

Farmers in the United States, however, have grown soybeans for only about a century. Tommy Carter says the soybeans they grown grow are for the most part genetic genetically similar. More differencesall * , or diversification, could better protect crops against climate changes that can reduce the production. Those changes include warter short water shortages which includes could increase from global warmwarming.
