More crop per drop. This is the mantra of the Bill & Melinda Gates Foundation in dealing with world hunger and a looming water shortage, foundation CEO Jeff Raikes said. Scientists are charting significant progress in developing high-yield crops and improving farming practices. The key now is to bring these technologies to sub-Saharan Africa, South Asia and other places where such technologies are urgently needed, Raikes told participants at an international water conference.“I see the linkage of the water crisis and the future of global poverty, yet I don’t see the general awareness of this issue,” Raikes was quoted by The Associated Press. “I don’t hear the talk of securing water for food.If farming methods and water management in poor communities are not improved, the amount of water required to meet global demand for food will almost double by 2050, Raikes said.
