The global water challenge – Modeling green and blue water
With rapidly growing freshwater demands in particular for food production, and increasingly uncertain water supplies due to climate change, there is an urgent need for a new approach to water management. Integrated Water Resources Management (IWRM) has been widely recognized as a pathway towards sustainability.
There are converging messages about green and blue water availability, use (and overuse) and potentials for increasing productivity, globally and in different regions of the world. Effects of management options such as rainwater harvesting, small scale storage, supplementary irrigation, improved irrigation and fertilization, as well as expansion of agricultural land, virtual water trade and investments in agricultural water management have been quantified by the different models.
