"In the wake of a major global food crisis in 2007 and 2008, cereal prices are expected to be higher and more volatile in the coming years," said Colin Chartres, director general of IWMI, whose research is supported by the Consultative Group on International Agricultural Research (CGIAR). "Asia's food and feed demand is expected to double by 2050. Relying on trade to meet a large part of this demand will impose a huge and politically untenable burden on the economies of many developing countries. The best bet for Asia lies in revitalizing its vast irrigation systems, which account for 70 percent of the world's total irrigated land."
Asian agriculture registered dramatic advances during the 1960s and 1970s through a combination of irrigation, improved crop varieties and fertilizers. The resulting Green Revolution made it possible to avert widespread hunger and raise living standards. From 1970 to 1995, the area under irrigation in Asia more than doubled, according to the IWMI-FAO report, making this the world's most intensively irrigated continent.
"Today, the option of expanding irrigated land area in Asia to feed a growing population is becoming increasingly problematic due to land or water constraints,"
