Water Footprint and Virtual Water Trade in Spain, 2010 Policy Implications Natural Resource Management and Policy Series, Vol. 35

1.1 General Framework In most arid and semi-arid countries, water resource management is an issue that is both important and controversial. Most water resources experts now acknowledge that water conflicts are not caused by physical scarcity but are mainly due to poor water management (Rosegrant et al. 2002; Benoit and Comeau 2005; Comprehensive Assessment of Water Management in Agriculture 2007; Garrido and Dinar 2010, among others). The scientific and technological advances of the past 50 years have led to new ways to solve many water-related conflicts, often with tools that seemed unthinkable a few decades ago (Llamas 2005; Lopez-Gunn and Llamas 2008). This study deals with the estimation and analysis of Spain?s water footprint, both from a hydrological and economic perspective. Its ultimate objective is to report on the allocative efficiency of water and economic resources. This analysis can provide a transparent and multidisciplinary framework for informing and optimising water policy decisions, contributing at the same time to the implementation of the EU Water Framework Directive (WFD) (2000/60/EC). It also responds to the current mandate of the Spanish Ministry of Environment and Rural and Marine Affairs, which recently issued instructions for drafting river basin management plans in compliance with the EU Water Framework Directive, with a deadline of end of year 2009 and then every 6 years (BOE 2008).

Literature Review.- Methodological Approaches.- Data and Limitations.- Spain’s Water Footprint.- Net Virtual-Water “Flows”.- Bringing the Analysis to the Policy Context.- Summary and Conclusions.

Provides geographical analysis (provincial and basin levels) over a ten-year period 1996-2006 Evaluates water footprint not only in terms of quantity and quality, but also in Euro terms, allowing for an analysis of the value of water use in the regions, in time and in virtual water exports Explores the linkages between agricultural and water policies
