Note publique d'information : The evaluation of the water footprint and virtual water trade has become a promising
means to evaluate the sustainability of a country’s water resources. This book is
based on the research and results of a thorough study carried out for Spain, which
serves as a leading case for a semi-arid country. The objective of this study was
to assess and analyze Spain’s virtual water use and water footprint, differentiating
the green and blue (surface and groundwater) components, both from a hydrological
and economic perspective. This contributes to the water footprint and virtual water
literature in several ways. By evaluating both water footprint and virtual water over
time and at the provincial scale, the analysis allows for policy-relevant conclusions
at the river basin level. By separating green and blue water components, and evaluating
all crops at the provincial level, the study enables a finer analysis of how water
footprint and virtual water vary during droughts and water shortages. The linkage
between commodities trade and water scarcity was explored to determine the extent
to which virtual water trade has the potential to deal with water-stressed periods.
The analysis contained in this study includes both market and non-market dimensions
and will appeal to researchers in both resource economics and hydrology as well as
policy-makers concerned with water-related issues
