India Info Line (August 23, 2011) | Increasing regions of the world are facing water scarcity and face the risk of progressive breakdown of their productive capacity under a combination of demographic pressure and unsustainable agricultural practices, according to a latest update from the Food and Agriculture Organization (FAO). Toward 2050, rising population and incomes are expected to require 70 percent more food production globally, and up to 100% more in developing countries, stated FAO’s Assistant Director-General for Natural Resources, Alexander Muller. Muller further stated that physical limits to land and water availability within these systems may be further exacerbated in places by external factors, including climate change, competition with other sectors and socio-economic changes.
