Sustaining irrigated agriculture for food security: a perspective from Pakistan.
Humanity is facing an enormous challenge in managing water to secure adequate food production. By the middle of this century, the world?s population is projected to reach 9.1 billion, 34 percent higher than today. Nearly all of this increase will occur in developing countries. In order to respond to the expected demand of this larger, more urban and, on average, richer population, food production must increase by about 70% as estimated by the FAO.
