“…Most of the global and regional climate models predict an increase in 10.1002/2017EF000545 temperature, and a decrease in precipitation, with a general increase of variability [AEMET, 2008]. Analyses of the effect of climate change on future water resources forecast important reductions in hydrological inflows to rivers [Chirivella Osma et al, 2015] and groundwater recharge [Pulido-Velazquez et al, 2015], resulting in an overall decrease of water availability and more frequent and more intense drought episodes [Hernández-Barrios, 2007;CEDEX, 2010;Escriva-Bou et al, 2017]. These climate change-related impacts have severe social and economic implications, and create further hydrological problems like the rise of salinity in coastal aquifers and increased water quality problems.…”

South‐east Spain is a drought prone area, characterized by climate variability and water scarcity. The Jucar River Basin, located in Eastern Spain, has suffered many historical droughts with significant socio‐economic impacts. For nearly a hundred years, the institutional and non‐institutional strategies to cope with droughts have been successful through the development of institutions and partnerships for drought management including multiple actors. In this paper, we show how the creation and institutionalisation of Multi‐Sector Partnerships (MSPs) has supported the development of an efficient drought management. Furthermore, we analyze the performance of one of the suggested instruments by the partnership related to drought management in the basin. Two methodologies are used for these purposes. On one hand, the Capital Approach Framework to analyze the effectiveness of the governance processes in a particular partnership (Permanent Drought Commission), which aims to highlight the governance strength and weakness of the MSP for enhancing drought management in the Jucar River Basin. Through a dynamic analysis of the changes that the partnership has undergone over time to successfully deal with droughts, its effectiveness on drought management is demonstrated. On the other hand, an econometric approach is used to analyze the economic efficiency of the emergency drought wells as one of the key drought mitigation measures suggested by the Permanent Drought Commission and implemented. The results demonstrate the potential and efficiency of applying drought wells as mitigation measures (significant reduction of economic losses, around 50 M€ during the drought period, 2005–2008).

“…Different non-global empirical models could be applied to assess the historical E from T series (e.g. Turc, 1954Turc, , 1961Coutagne, 1954;Budyko, 1974; amongst others) as described in Arora (2002), Gerrits et al (2009), and España et al (2013).

Abstract. Any change in the components of the water balance in a coastal aquifer, whether natural or anthropogenic, can alter the freshwater–salt water equilibrium. In this sense climate change (CC) and land use and land cover (LULC) change might significantly influence the availability of groundwater resources in the future. These coastal systems demand an integrated analysis of quantity and quality issues to obtain an appropriate assessment of hydrological impacts using density-dependent flow solutions. The aim of this work is to perform an integrated analysis of future potential global change (GC) scenarios and their hydrological impacts in a coastal aquifer, the Plana Oropesa-Torreblanca aquifer. It is a Mediterranean aquifer that extends over 75 km2 in which important historical LULC changes have been produced and are planned for the future. Future CC scenarios will be defined by using an equi-feasible and non-feasible ensemble of projections based on the results of a multi-criteria analysis of the series generated from several regional climatic models with different downscaling approaches. The hydrological impacts of these CC scenarios combined with future LULC scenarios will be assessed with a chain of models defined by a sequential coupling of rainfall-recharge models, crop irrigation requirements and irrigation return models (for the aquifer and its neighbours that feed it), and a density-dependent aquifer approach. This chain of models, calibrated using the available historical data, allow testing of the conceptual approximation of the aquifer behaviour. They are also fed with series representatives of potential global change scenarios in order to perform a sensitivity analysis regarding future scenarios of rainfall recharge, lateral flows coming from the hydraulically connected neighbouring aquifer, agricultural recharge (taking into account expected future LULC changes) and sea level rise (SLR). The proposed analysis is valuable for improving our knowledge about the aquifer, and so comprises a tool to design sustainable adaptation management strategies taking into account the uncertainty in future GC conditions and their impacts. The results show that GC scenarios produce significant increases in the variability of flow budget components and in the salinity.

“…A world with more population-rising urban water use, and greater water demands for food and energy production-, a changing climate, and the many water-dependent ecosystems in crisis, challenge how we plan and manage water (Roy et al, 2012;Vörösmarty et al, 2000). At the same time, the high energy use in supplying, conveying, treating and using water, place water systems both as a source of greenhouse gas emissions (Reffold et al, 2008) and as a vulnerable stakeholder facing climate change (Pathak et al, 2018;Escriva-Bou et al, 2017). To deal with such complex systems, planners and managers need comprehensive and integrated tools to understand the tradeoffs that involve their decisions.…”

Highlights• We develop an integrated water-energy-GHG emissions model • Water-related energy use and/or production are included for each water demand • Water allocation is modeled using a mixed simulation/optimization algorithm • 13% of electricity and 5% of GHG emissions are related with water use in California • Several scenarios show the tradeoffs between water, energy, and GHG emissions AbstractIntegrating processes of water and energy interdependence in water systems can improve the understanding of the tradeoffs between water and energy in management and policy. This study presents a development of an integrated water resources management model that includes water-related energy use and GHG emissions. We apply the model to a simplified representation of California's water system. Accounting for water demands from cities, agriculture, environment and the energy sector, and combining a surface water management model with a 2 simple groundwater model, the model optimizes water use across sectors during shortages from an economic perspective, calculating the associated energy use and electricity generation for each water demand. The results of California's water system show that urban end-uses account for most GHG emissions of the entire water cycle, but large water conveyance produces significant peaks over the summer season. Different policy scenarios show the significant tradeoffs between water, energy, and GHG emissions. Keywords Water-Energy Nexus; GHG Emissions; Integrated Water Management; HydroeconomicModeling. Software and/or data availability sectionThe inputs and outputs are managed via an Excel spreadsheet and the model is programed using Visual Basic for Applications (VBA) and embedded in the spreadsheet.
