“…The evidence of the empirical and theoretical literature review suggest that when traditional surface (furrow) systems are replaced by sprinkler and drip irrigation, water abstraction (use) is reduced in a significant number of studies, among others in: Jackson et al 2010;López-Gunn et al 2012;García-Mollá et al 2013;Soto-García et al 2013;Graveline et al 2013;Heumesser et al 2012;Törnqvist and Jarsjö 2012;Peterson and Ding 2005).…”

“…Other empirical analyses of the transformation of irrigated systems in Spain with the abovementioned land constraints have been conducted by Soto-García et al (2013), Fernández-García et al (2014 and García-Mollá et al (2013). All the authors concluded that water diversion (abstraction) was significantly reduced (by 25%-45%), but that water depletion (evapotranspiration) did not increase.…”

POST-PRINT VERSION AbstractThe hypothesis of a rebound effect as a consequence of water saving investments is taken analogically from the Jevons paradox models in energy economics. The European Commission (EC) alert about the consequences in water stressed regions that are investing heavily in modernization of irrigation networks and systems. This paper reviews the literature, linking water savings with water diversion and water depletion, both from theoretical models and empirical evidence from the published research. In order to increase knowledge of this phenomenon, a new empirical case study is presented based on a survey of 36,000 ha of recently modernized irrigated areas in the Guadalquivir basin (southern Spain). The results of the case study illustrates the conditions that may avoid rebound effect, although the results of the available empirical evidence and the published theoretical research are diverse and lead to contradictory results. Further research is therefore needed to determine the causes and solutions of water saving investment impacts and the possible speculative rebound effect.Keywords: Water conservation; Jevons paradox; Rebound effect; Water pricing; Water use; Water consumption; Spain Highlights The present study analyzes the theoretical and empirical evidence that water saving investments may lead to increased water use and/or consumption. Some authors suggest that if irrigated land expansion is not constrained, increased water abstractions are likely to occur. When land expansion is constrained and water rights are controlled, water depletion does not increase. The results of published research are diverse and have yielded contradictory results regarding the rebound effect as a consequence of water saving investments.

“…For instance, the water available to the ARJ district has been reduced from 700 to 200 M m 3 in the last 40 years. Consequently, the dwindling return flows from the irrigation districts have caused serious environmental problems to the Albufera wetland, the main aquatic ecosystem in the JRB, which is mostly fed by these return flows (García-Molla et al, 2013).…”

s u m m a r yGrowing water extractions combined with emerging demands for environment protection increase competition for scarce water resources worldwide, especially in arid and semiarid regions. In those regions, climate change is projected to exacerbate water scarcity and increase the recurrence and intensity of droughts. These circumstances call for methodologies that can support the design of sustainable water management. This paper presents a hydro-economic model that links a reduced form hydrological component, with economic and environmental components. The model is applied to an arid and semiarid basin in Southeastern Spain to analyze the effects of droughts and to assess alternative adaptation policies. Results indicate that drought events have large impacts on social welfare, with the main adjustments sustained by irrigation and the environment. The water market policy seems to be a suitable option to overcome the negative economic effects of droughts, although the environmental effects may weaken its advantages for society. The environmental water market policy, where water is acquired for the environment, is an appealing policy to reap the private benefits of markets while protecting ecosystems. The current water management approach in Spain, based on stakeholders' cooperation, achieves almost the same economic outcomes and better environmental outcomes compared to a pure water market. These findings call for a reconsideration of the current management in arid and semiarid basins around the world. The paper illustrates the potential of hydro-economic modeling for integrating the multiple dimensions of water resources, becoming a valuable tool in the advancement of sustainable water management policies.

“…Hence, the impact of policies on irrigation modernization is uncertain; particularly the degree to which the introduction of new technologies might help to reduce rates of water use and consumption [8]. Although changing irrigation systems, from furrow to micro-irrigation (i.e., drip method), has reduced water use in some cases [9,10], other studies suggest it has been associated with increased water and energy consumption [11,12].…”

Abstract:The sustainable management of natural resources, and particularly groundwater, presents a major challenge in arid regions to ensure security of water supply and support agricultural production. In many cases, the role of smallholder farmers is often neglected when managing irrigated water and land processes. However, management decisions have a major impact on farmers' livelihoods, and it is essential: first, to recognise the crucial role of regional and local social, political and economic systems; and second, to integrate farmers' perspectives in the governance and management of local groundwater practices. This is particularly important as the ways in which arid region farmers use land and water have wider implications for land degradation and salinization. This paper uses a community-based approach to identify and examine the social, economic and cultural dimensions to groundwater irrigation systems from the perspective of local farmers in central Iran. The paper utilises interviews with local farmers and water agencies in Iran to reflect on their respective roles within the irrigation system and in developing management plans for the sustainable use of groundwater. Through social research, we investigate the reasons why farmers might reject government irrigation management schemes and outline how local problems with land degradation and salinization and reduced water availability have arisen as a result of changing management policies. In conclusion, we identify future challenges and consider appropriate future management strategies.
