“…Also we may think of clear ones from flood control and others from the dams' construction. In any case for the particular purposes here we decided to focus on the dams constructed with the purposes or with main uses of agricultural production, excluding those with clear associated benefits that relate less clearly to changes in WFs, such as hydroelectric production [65,66].…”

Abstract:In the context of a relatively scarce water country, the article analyzes the changes in 50 years in the water footprint (WF) in Spain evaluating its sustainability. For that purpose, firstly we make use of the regional information of the water footprints and crop production to estimate the WF of production over the 50 provinces in Spain, looking at the variation between the years 1955 and 2005-2010. The detail in the information of crops (more than 150 of them) statistics allows us to examine the types and origin of changes (in volume produced, shifts towards more or less water intensive crops). Secondly, we estimate sustainability indicators also at the provincial level, which let us evaluate whether this change has created or incremented the risk of physical and economic water stress. Thirdly, we introduce the economic perspective, providing evidence on the infrastructures built and public sector expenditure, as an approximation to the costs of the increases in WF, particularly meaningful for those water stressed areas.

“…Most of these areas were developed in the early twentieth century pursuing social purposes. In Aragon, irrigation development projects were promoted by the Spanish government aimed at improving the standard of living in rural areas and achieving food self‐sufficiency in the country (Silvestre and Clar, ). Now, most of these projects are being modernized by switching from surface to sprinkler/trickle irrigation and incorporating telecontrol systems.…”

This study is an analysis of the influence that the socio‐economic context may have on irrigation performance. The main objective is to provide useful information to support the decision‐making processes of farmers, water user associations, policy‐makers and agritech companies. For this purpose, 34 centre pivots were evaluated in Aragon (Spain) and Utah (USA). Utah has a lower agricultural production potential than Aragon, and crop production is a secondary activity with respect to livestock production on many farms. In Aragon, farms are mainly devoted to crop production. These and other features may bias farmers' decisions regarding investment, operation and maintenance of their irrigation systems. This bias may be the underlying cause of the lower irrigation uniformity obtained in Utah. Coefficients of uniformity (CU) averaged 90% in Aragon and 80% in Utah. The gap between the actual and potential (90%) CU translates into an estimated net land productivity reduction of −18% (€66 ha−1, US$89 ha−1) in Utah. Measures aimed at closing this gap could cost less than €15 ha−1 (US$20 ha−1). Multidisciplinary approaches are required to quantify these gaps and to understand their causes in order to bridge them in a cost‐effective manner. Copyright © 2016 John Wiley & Sons, Ltd.

“…Our model represents the economy of Huesca province. This province is selected because it contains the largest irrigation scheme in Spain, the Upper Aragon Irrigation Scheme (CGRAA is the Spanish acronym), that is one of the most ambitious projects of its kind in the country [31]. The CGRAA irrigates more than 125,000 hectares of land and comprises 58 irrigation sub-schemes, supplying water to a number of municipalities, as well as 10 industrial estates.…”

The benefits of technological improvement are uncertain. The timing of the introduction and take-up of new technologies is difficult to estimate. Technological improvements play a decisive role in water policy. In the context of water policy design, we evaluate the implications of uncertainty in the gradual process of enhancements to the efficiency of irrigation water use, for a better understanding of the extent to which these improvements could mitigate the output losses derived from water constraints. To accomplish this, we address simultaneous sensitivity analyses within a dynamic Computable General Equilibrium (CGE) model to analyze different uncertainty scenarios. Our results show that the date on which advanced technology becomes available and enters general use is quite significant. The greater and faster the improvements in irrigation technologies, the better.
