ABSTRACT
In the beginning of the 21st century, water to support food production seems to stand at a crucial juncture. Projections of water availability remain complex and uncertain (Vorosmarty et al., 2010), not least due to changes in population, consumption patterns and environmental policy (Iglesias et al., 2011a). Research and technology have been unusually vigorous and have shed light on many possible innovations (Sunding and Zilberman, 2001: Nordhaus, 2002; Smit and Skinner, 2002). Part of this transformation is due to the pressure of agricultural practices and policies to face climate change, especially in relation to water for agricultural production.
