Drought is a climatic risk with notable repercussions on water supply systems. The aim of this study is to analyze the principal measures for management and planning implemented during recent decades in south-eastern Spain (Segura River Basin) to respond to drought situations, focusing on the role played by non-conventional water resources (desalination and treated water). The results demonstrate that the study area (despite being one of the driest places of Spain) is less vulnerable to drought than regions with an Atlantic climate and greater availability of water. This has been possible thanks to the integration of non-conventional water resources as a means of adaptation to confront this natural risk, which is estimated to become more intense and frequent in the future owing to climate change.

Since the past few years, the smart city paradigm has been influencing sustainable urban water resources management. Smart metering schemes for end users have become an important strategy for water utilities to have an in-depth and fine-grained knowledge about urban water use. Beyond reducing certain labor costs, such as those related to manual meter reading, such detailed and continuous flow of information is said to enhance network efficiency and improve water planning by having more detailed demand patterns and forecasts. Research focusing on those initiatives has been very prolific in countries such as Australia. However, less academic attention has been paid to the development of smart metering in other geographies. This paper focuses on smart water metering in Spain and, more particularly, documents and reflects on the experience of the city of Alicante (southeastern Spain), a pioneer case of massive deployment of remote reading of water meters at the household level and for large urban customers. Through data and interviews with water managers from the water utility, we shed light on the costs and early benefits, as well as the potentialities and (unexpected) problems of this technology to contribute to more sustainable urban water cycles.

The European Mediterranean coastline has experienced major tourism-related urbanization since 1960. This is a dynamic that has led to increased spending on water consumption for urban and tourism-related uses. The objective of this paper is to define and to analyze how domestic water consumption in the city of Alicante evolved between 2000 and 2013. Real billing figures for individual households were analyzed according to the type of housing and the income level of the occupants. The conclusions drawn show that consumption fell over the period studied, and that there are different patterns in water expenditure depending on the type of housing and the inhabitants.

One of the subject areas that is currently most prominent in the field of education (Social Science) is climate change, given its implications for raising awareness and training the present and future society. The objectives of this study, focused on school children (Primary Education—10 to 12 years old; third cycle, Secondary Education—12–16 years old; and pre-university, Baccalaureate—17–18 years old) in the Region of Valencia (Spain), are to analyse the following: the main information channels through which children receive information on climate change; the causes and consequences that they identify with respect to this phenomenon; and the main greenhouse gas that they believe is in the atmosphere. Based on the 575 students surveyed during the academic year 2020–2021, the results indicate that the three main information media are digital (TV—82.8%, Internet—56.2% and social networks—49.4%). With respect to the causes of the phenomenon identified by the students, particularly noteworthy was pollution (70.1%) and, in terms of the effects, the increase and changes in temperature (61.7%) were of particular note. Finally, with reference to greenhouse gases, the majority responded CO₂ (63.5%). This is incorrect, as the main greenhouse gas in the atmosphere is water vapour. To sum up, we can highlight the role played by schools in training the future society and the risk arising from an increase in the information received from digital media by children as they grow older, due to the danger of misinformation.
