“…On the other hand, the recipients mention the far-reaching socio-economic impact of the uses that benefit from this water. Today, 50% of the productive wealth of the recipient basin of the TSA depends on the contribution of the waters from the river Tagus [29], owing to which these recipient areas should seek solidarity with the donors and never forget their dependence on them. Furthermore, the closure of the TSA would imply greater overexploitation of the groundwater in the recipient basin, impoverishing the ecosystems as they lose biodiversity and their capacity for regeneration.…”

“…To guarantee water demands, the south-east of Spain-the area that benefits from the TSA-has made use of traditional solutions, such as transfers and the exploitation of aquifers, together with an increased use of non-conventional sources (desalination and treated reused water) and higher efficiency in the use of water for irrigation and supply [29,30]. All of this should be correlated with the intrinsic characteristics of the recipient basin of this transfer (the Segura basin), which is characterized by an extreme natural scarcity of water resources due to climatic, hydrographic, and hydrogeological factors [31].…”

Challenges and Proposals for Socio-Ecological Sustainability of the Tagus–Segura Aqueduct (Spain) under Climate Change

2017

Abstract:Since its inauguration in 1979, the Tagus-Segura Aqueduct has become one of the hydraulic infrastructures that has had the most significant socio-economic repercussions in Spain during the past few decades. The aqueduct is significant for its strategic importance and developmental potential for south-east Spain, where it provides water for agriculture as well as for tourism and urban consumption. The aim of this study is to analyze the uncertainties regarding the future functioning of this infrastructure in view of the reduction of water resources and a higher frequency of drought episodes due to climate change. To this end, an analysis was performed on previous studies of hydrological plans, regulations and studies on climate change in order to enable an assessment to be made of the possible effects of these changes on the normal functions of the Tagus-Segura Aqueduct. Consideration is also given to the new management rules that have regulated this infrastructure since 2014, the use of alternative water resources, and proposals such as measures to increase resilience in light of future climate change scenarios and their effects on the Mediterranean.

“…The main components of the system are Guadalest and Amadorio reservoirs that are mainly used for urban supply. Both reservoirs were originally built for irrigation purposes, but the Consorcio de Aguas de la Marina Baja has promoted agreements with farmers by which these trade their water with Benidorm and other towns' treated wastewater of enough quality to be used for irrigation, and obtain several compensations in return [36]. The availability of natural water resources (i.e., precipitation, river flow and groundwater) in the watersheds has been highly irregular over time and still is.…”

Assessing Water Availability in Mediterranean Regions Affected by Water Conflicts through MODIS Data Time Series Analysis

et al. 2019

Water scarcity is a widespread problem in arid and semi-arid regions such as the western Mediterranean coastal areas. The irregularity of the precipitation generates frequent droughts that exacerbate the conflicts among agriculture, water supply and water demands for ecosystems maintenance. Besides, global climate models predict that climate change will cause Mediterranean arid and semi-arid regions to shift towards lower rainfall scenarios that may exacerbate water conflicts. The purpose of this study is to find a feasible methodology to assess current and monitor future water demands in order to better allocate limited water resources. The interdependency between a vegetation index (NDVI), land surface temperature (LST), precipitation (current and future), and surface water resources availability in two watersheds in southeastern Spain with serious difficulties in meeting water demands was investigated. MODIS (Moderate Resolution Imaging Spectroradiometer) NDVI and LST products (as proxy of drought), precipitation maps (generated from climate station records) and reservoir storage gauging information were used to compute times series anomalies from 2001 to 2014 and generate regression images and spatial regression models. The temporal relationship between reservoir storage and time series of satellite images allowed the detection of different and contrasting water management practices in the two watersheds. In addition, a comparison of current precipitation rates and future precipitation conditions obtained from global climate models suggests high precipitation reductions, especially in areas that have the potential to contribute significantly to groundwater storage and surface runoff, and are thus critical to reservoir storage. Finally, spatial regression models minimized spatial autocorrelation effects, and their results suggested the great potential of our methodology combining NDVI and LST time series to predict future scenarios of water scarcity.

“…Rico (2007) realizó una primera aproximación sobre las diferencias de consumo en un núcleo turístico masivo en función de la tipología de los establecimientos hoteleros y residenciales (apartamentos). Este enfoque, a partir de datos reales de consumo, ha sido actualizado en el trabajo de Rico et al (2009) y, posteriormente, en la investigación sobre los efectos de la gran transformación de suelo ocurrida en las dos últimas décadas en el litoral alicantino por Rico et al (2013).…”

“…A ello se une la disminución de recursos hídricos prevista por efecto del cambio climático en el litoral mediterráneo español y sus consecuencias para la actividad turística, aspecto que ha sido abordado por Rico et al (2013). Los efectos de la reducción de precipitaciones en las regiones de la fachada mediterránea española (AEMET, 2015) y de los cambios en los patrones de precipitación (De Luis et al, 2005) han servido de base para el estudio del grado de resiliencia de este territorio y sus actividades económicas, básicamente la agraria y la turística (Olcina, 2012;Olcina et al, 2014).…”

RESUMENLa garantía de abastecimiento de agua es una condición básica para el mantenimiento de los estándares de calidad de un núcleo turístico. Benidorm es la ciudad turística más importante del litoral mediterráneo español por su número de plazas hoteleras. La adaptación a la sequía ha sido una constante desde mediados del pasado siglo en este destino turístico. Se han llevado a cabo medidas municipales y supramunicipales para asegurar el suministro de agua potable y, asimismo, medidas desde el sector hotelero que han permitido reducir de manera significativa el consumo de agua por persona y día entre 1975 y 2015. El umbral de riesgo de sequía se ha reducido drásticamente a partir de la creación del Consorcio de aguas comarcal y de la implantación de sistemas de aprovechamiento de recursos de agua no convencionales (aguas depuradas y desalación).Palabras clave: abastecimiento de agua, sequías, turismo, Benidorm, medidas de ahorro, hoteles. ABSTRACTWater supply guarantee is a basic condition for maintaining the quality standards of a tourist town. Benidorm is the most important tourist center in Spanish Mediterranean coast by its number of hotel rooms. The adaptation to droughts has been a constant since the middle of last century in this tourist town. It have been carried out municipal and supra-municipal measures to ensure consumption of potable water, and also actions from the private hotel sector that have reduced significantly the consumption of water per person per day, between 1975 and 2015. Drought risk has been drastically reduced from the creation of the supra-municipal water agency and the implementation of systems that use non-conventional water resources (treated wastewater and desalination).
