Global water news (March 2009)

Abstract

Global news Acute food shortages predicted for end of century Rapidly warming climate is likely to seriously alter crop yields in the tropics and subtropics by the end of this century and, without adaptation, will leave half the world’s population facing serious food shortages, new research shows. “The stresses on global food production from temperature alone are going to be huge, and that doesn’t take into account water supplies stressed by the higher temperatures,” said David Battisti, a University of Washington atmospheric sciences professor. Battisti is lead author of the study in the 9 January edition of Science. He collaborated with Rosamond Naylor, director of Stanford University’s Programme on Food Security and the Environment, to examine the impact of climate change on the world’s food security. “This is a compelling reason for us to invest in adaptation, because it is clear that this is the direction we are going in terms of temperature and it will take decades to develop new food crop varieties that can better withstand a warmer climate,” Naylor said.
