Lessons from success and/or failure of irrigation development
World population is increasing, particularly in the developing countries. Groundwater reserves are being depleted; lands are being degraded. The required increase in food production must come principally from new supplies of water for irrigated lands. If irrigated lands fail to produce the required food, increased destruction of resources and degradation of the environment from increasing slash and burn agriculture is anticipated. Various countries and international agencies have recognized the possibility of future food shortage.
