“…In south-eastern Spain, groundwater abstraction costs for irrigation vary between 0.15 and 0.5 €/m 3 , most frequently close to the upper limit, depending on circumstances (Calatrava and Martínez-Granados, 2012;Martínez-Vicente et al, 2013;CHJ, 2015). Environmental costs due to groundwater abstraction should be added.…”

“…Its Mediterranean climate is characterized by a severe dry summer followed by sporadic intense rains in autumn, and frequent multi-annual droughts. For more information on the physical environment and irrigated agriculture, see Calatrava and Martínez-Granados (2012).…”

“…On top of the low rainfall, there is a large demand for water for the production of highly profitable fruit and vegetable crops, alongside sizeable population growth and the expansion of tourism over the last two decades. Against this backdrop of increasing scarcity, where there is high awareness regarding the conservation of water resources and their dependent ecosystems, the allocation of water generates major conflicts among users, which come to a head during frequent drought episodes (Calatrava & Martínez-Granados, 2012).…”

“…It is conventional wisdom that irrigation is the lowest-value water use and desalination the highest-cost water source, but the value of irrigation water in Spain can exceed the cost of desalination (Calatrava & Martínez-Granados, 2012). This potential surplus explains why treatment plants are desalinating seawater and brackish water and recycling wastewater for irrigators in Almería, but it does not explain why farmers are paying a fraction of the cost for a fraction of the desalinated water produced (GWI, 2015).…”
