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 scientific understanding of climate change is firmly established; it is occurring, it is primarily due to human activities, and it poses potentially serious risks to human and natural systems. Nevertheless, public understanding of this phenomenon varies widely among farmers and the public, the two-target audience of this paper. This paper introduces two research questions: (1) How climate change is perceived by public-farmers’ nexus; and (2) How perception and populism (as a thin-ideology moved by social forces) interact? In order to address both questions, we review insights from different sources (literature, research projects, and public opinion services) over the last 10 years. The results proved how public experience of climate change is interdependent with the belief that climate change is happening. What is also notable is that the greater the years of farmers’ farming experiences, the greater the percentage rate of their climate change awareness. Differences among farmers and public perceptions were also noted. Uncertainty, coupled with skepticism, the media, and political will, are common findings when asking to farmers and the public for the main weaknesses in adaptation to climate change. However, scientific consensus, meteorological data, barriers to adaptation, and the role of technology are subjects in which both differ.

Water consumption continues to grow globally, and it is estimated that more than 160% of the total global water volume will be needed to satisfy the water requirements in ten years. In this context, non-conventional water resources are being considered to overcome water scarcity and reduce water conflicts between regions and sectors. A bibliometric analysis and literature review of 81 papers published between 2000 and 2020 focused on south-east Spain were conducted. The aim was to examine and re-think the benefits and concerns, and the inter-connections, of using reclaimed and desalinated water for agricultural and urban-tourist uses to address water scarcity and climate change impacts. Results highlight that: (1) water use, cost, quality, management, and perception are the main topics debated by both reclaimed and desalinated water users; (2) water governance schemes could be improved by including local stakeholders and water users in decision-making; and (3) rainwater is not recognized as a complementary option to increase water supply in semi-arid regions. Furthermore, the strengths–weaknesses–opportunities–threats (SWOT) analysis identifies complementary concerns such as acceptability and investment in reclaimed water, regulation (cost recovery principle), and environmental impacts of desalinated water.

The successes and failures of water reuse schemes are shaped by complex interrelationships between technological, economic, and socio-political factors. However, it has long been recognized that the main challenges to more effective water management are largely social rather than technical. This article reviews the recent literature (2007–2017) to analyze driving factors associated with farmers’ concerns and public perception of reclaimed wastewater for irrigation. The aim of the paper is to synthetize how both environmental and health risks and the yuck factor could be addressed in order to promote mutual understanding between farmers and the public. Results show: (1) how farmers and the public perceive environmental and health risks in a similar way, (2) how the yuck factor is more noticeable for the public than farmers, and (3) how constructed wetlands, reclaimed water exchange consortiums, product certification, and direct site visits to water reuse infrastructure could be promoted in order to foster understanding between farmers and the public. The article concludes by providing key research questions for managers and public authorities relating to how to focus on the study of technical and social issues related to water reuse.

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.

Although desalination water cost and quality standards have been widely studied, less attention has been paid to understanding how desalination plant managers and irrigation communities interact to address water scarcity. This paper aims to approach these questions from experience in Alicante and Murcia (Spain). Two specific questionnaires have been applied to (1) three desalination plants managed by the Spanish public company ACUAMED, and (2) 11 irrigation communities who use desalinated seawater. Discursive analysis has been applied in order to deepen understanding on the driving factors, benefits, and barriers of desalination use and management. Results highlighted how (1) irrigation communities consider desalination as a complementary water source to be combined with conventional water resources, (2) both ACUAMED and irrigation communities highlighted two main advantages of desalination: the security/guarantee of supply and water quality parameters, and (3) managers and irrigators disagree on the desalination model of seawater provision and management, since irrigators consider that the Central Union of the Tajo-Segura transfer irrigators (SCRATS) should have a leading role. In addition, the main driving factors and barriers useful for policy makers when closing the gap of desalination have been identified: water price and energy consumption; lack of water storage capacity and regulation; environmental impacts.
