“…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).…”

“…They also observed a four-fold increase in management, operation and maintenance costs than before modernization mainly due to energy costs, as well as an improvement in the apparent economic productivity as in Lecina et al (2010). Jackson et al (2010) analysed two different irrigation areas in Australia after the conversion of flood irrigation systems into pressurized systems. The results showed a 10%-66% reduction in water use, but as much as a 163% increase in energy consumption in the area irrigated by surface irrigation systems.…”

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.

“…The decision to invest in irrigation technology traditionally depends on the water conservation benefits of the new technologies, and the costs associated with implementing the technology change (Qureshi et al, 2001;Pratt Water, 2004;Mackinnon et al, 2009). Increasing concerns about energy dependency and levels of GHG emissions (Zillman et al, 2008;Jackson et al, 2010) have been largely ignored in irrigation technology adoption decisions. Analysis of trade-offs is critical to ensuring that the economic efficiency of agricultural production is maintained, while environmental impacts are minimized.…”

The Australian Government is meeting the challenge of water scarcity and climate change through significant on-farm infrastructure investment to increase water use efficiency and productivity, and secure longer term water supplies. However, it is likely that on-farm infrastructure investment will alter energy consumption and therefore generate considerable greenhouse gas (GHG) emissions, suggesting potential conflicts in terms of mitigation and adaptation policies. In particular, the introduction of a price on carbon may influence the extent to which new irrigation technologies are adopted. This study evaluated trade-offs between water savings, GHG emissions and economic gain associated with the conversion of a sprinkler (hand shift) irrigation system to a drip (trickle) irrigation system for a lettuce production system in the Lockyer Valley, one of the major vegetable producing regions in Australia. Surprisingly, instead of trade-offs, this study found positive synergies -a win-win situation. The conversion of the old hand-shift sprinkler irrigation system to a drip irrigation system resulted in significant water savings of almost 2 ML/ha, as well as an overall reduction in GHG emissions. Economic modelling, at a carbon price of $ 30/t CO2e, indicated that there was a net benefit of adoption of the drip irrigation system of about $ 4620/ML/year. We suggest priority should be given, in the implementation of on-farm infrastructure investment policy, to replacing older inefficient and energy-intensive sprinkler irrigation systems such as hand shift and roll-line. The findings of the study support the use of an integrated approach to avoid possible conflicts in designing national climate change mitigation and adaptation policies, both of which are being developed in Australia.

“…La comparación de estos resultados, sobre riegos de aguas superficiales en el Guadalquivir, con los obtenidos por los trabajos efectuados en aguas subterráneas en Murcia (Gómez Espín, 1997), no es contradictoria. De hecho, estudios efectuados en Australia (Jackson et al, 2010) concluyen que es frecuente obtener una reducción de consumo energético en los regadíos de aguas subterráneas, mientras que en zonas abastecidas por aguas superficiales la presurización trae consigo un incremento de los costes energéticos y por ende, los del riego. En estos casos llegan a recomendar centrar los esfuerzos en la mejora de los sistemas de riego por gravedad, evitando la presurización de la red.…”

“…Son las comunidades de regantes con aguas superficiales en las que se produce un aumento de las tarifas del riego por unidad de superficie, esto es debido a que antes de la modernización los precios del riego eran más bajos, al no tener costes energéticos significativos para la obtención del recurso. Se observa por tanto, un impacto diferente entre aguas superficiales y subterráneas, como ha detectado Jackson (2010).…”

RESUMENDurante los últimos treinta años, las administraciones públicas y las entidades de riego han efectuado un importante esfuerzo destinado a modernizar los regadíos valencianos. Esta política hidráulica, consecuencia de la adopción de un modelo de gestión de la demanda, se ha materializado en una importante expansión del riego por goteo. El artículo analiza, a partir de diversas entrevistas, los efectos de la modernización sobre unas entidades de riego que han experimentado cambios en la eficiencia del riego, organización, usos y costos de agua.Palabras clave: regadíos, modernización, riego por goteo, gestión de la demanda, polí-tica hidráulica. ABSTRACTDuring the last 30 years, regional and central administrations and farmers have done an important financial effort in order to promote irrigation modernization in the Valencia Region. This policy, a corollary of a National investment on demand management, has been materialized in an important expansion of drip irrigation techniques.
