“…Salt accumulation occurs in many irrigated systems, particularly in arid regions where the irrigation water is limited and the conflicts for water allocation are intermingled (e.g., [ 1 ]). Soil salinity substantially reduces income in irrigated agricultural systems around the world [ 2 , 3 ], as is the case of the Ebro valley, Spain [ 4 , 5 ], where salinity also causes non-point source pollution [ 6 ]. Soil salinity is a widespread limiting of the range of crops and their yields.…”

A key issue for agriculture in irrigated arid lands is the control of soil salinity, and this is one of the goals for irrigated districts when changing from flood to sprinkling irrigation. We combined soil sampling, proximal electromagnetic induction, and satellite data to appraise how soil salinity and its distribution along a previously flood-irrigated field evolved after its transformation to sprinkling. We also show that the relationship between NDVI (normalized difference vegetation index) and ECe (electrical conductivity of the soil saturation extracts) mimics the production function between yield and soil salinity. Under sprinkling, the field had a double crop of barley and then sunflower in 2009 and 2011. In both years, about 50% of the soil of the entire studied field—45 ha—had ECe < 8 dS m−1, i.e., allowing barley cultivation, while the percent of surface having ECe ≥ 16 dS m−1 increased from 8.4% in 2009 to 13.7% in 2011. Our methodology may help monitor the soil salinity oscillations associated with irrigation management. After quantifying and mapping the soil salinity in 2009 and 2011, we show that barley was stunted in places of the field where salinity was higher. Additionally, the areas of salinity persisted after the subsequent alfalfa cropping in 2013. Application of differential doses of water to the saline patches is a viable method to optimize irrigation water distribution and lessen soil salinity in sprinkler-irrigated agriculture.

“…According to Gómez (2002), although water pricing reflects an environmental perspective, this issue remains exclusively economic. In this sense, many authors have pointed out that waterpricing policies cannot offer the expected results and may have other, negative consequences (Berbel, Cañas, Gómez-Limón, López, & Arriaza, 1999;Berbel, Jiménez, Salas, Gómez-Limón, & Rodríguez, 1999;Feijoó, Calvo, & Albiac, 2000). Gómez (2002) also argues that if water pricing reduces profits by around 15-20% for farmers, farm income and competitiveness of agriculture in the irrigated areas will plummet, promoting a land-use change and the abandonment of farm activity in the less viable activities.…”

Water scarcity is a threat to food production systems, with appropriate water management being a major part of the solution. From the adoption of the European Water Framework Directive to the latest proposals for the Common Agricultural Policy Horizon 2020, the strategic lines for establishing a balance between agriculture and water resources in the European Union have been defined, including an emphasis on water pricing. This paper discusses the situation of irrigated agriculture in semi-arid areas such as southern Spain in terms of water scarcity, highlighting the main advantages and disadvantages of water-pricing policies as a solution to more sustainable irrigation management.

“…Existe muy poca información sobre funciones de demanda de agua en los distintos sectores, ya que hay grandes dificultades para realizar estimaciones econométricas al ser insuficiente la variación de los precios del agua para cualquier estimación fiable, y sólo existe información parcial sobre algunas zonas de regadío. A este respecto cabe citar los trabajos de Berbel et al (1999), Sumpsi et al (1998), y Feijoó et al (2000, en los que se estima la respuesta de la demanda de agua en zonas de regadío de los Valles del Guadalquivir, Duero, Júcar, Segura y Ebro. En el trabajo que se presenta en este artículo, el cálculo de la demanda del agua de uso agrario se basa en el modelo biofísico EPIC (Environmental Policy Integrated Climate) desarrollado por el equipo de…”

This paper analyzes the effects of some water management policies and irrigation systems on crop yields and water pollution, in an area located in the Flumen- Monegros irrigation district in Huesca (Spain). The analysis is performed using water and nitrogen crop response functions, which are estimated with the EPIC crop growth package. The estimation of response for the crop activities incorporates information on local climate, soils, crop management and irrigation systems. The relationship between yields and water and nitrogen input use is examined, in order to quantify the pollution reduction cost faced by farmers. The costs depend on the particular crop and the pollution abatement measure, and information on these costs is important to design efficient pollution abatement measures.
