The Council of the European Union places its trust in the tourism sector as a driving force for change on the continent, given its contribution to achieving high levels of employment and social welfare, sustainable growth, improved quality of life, and greater European integration, as well as increased economic and social cohesion, thus significantly facilitating the achievement of convergence objectives. Therefore, the development of tourism is closely linked to the economic and social growth of a given geographical area. Considering that Spain is the second most popular tourist destination in Europe, it is essential to promote the study and analysis of tourism trends in our country to ensure its sustainable development. Furthermore, it cannot be denied that tourism is fundamentally linked to water availability in a given geographical area. In Spain, the areas most in demand for tourism coincide with those experiencing the greatest hydrological problems. This water stress means that many tourist areas, mostly coastal, face significant problems with both the quantity and quality of their water supplies. Among these examples of geographical areas with water scarcity and high tourist demand is the case of the Canary Islands. Specifically, the Canary Islands' tourism sector ranks third in the number of foreign tourists received within the Spanish tourism market, which, according to data from the World Tourism Organization (2013), is the second most popular European destination, after France, absorbing more than 101% of international tourists visiting Europe. Among the distinctive characteristics of the Canary Islands as a tourist destination, the absence of seasonality stands out due to its mild climate year-round. This has led to continuous growth in tourist numbers since the 1960s, albeit with periods of acceleration and deceleration. While tourism in a region like the Canary Islands provides undeniable socioeconomic benefits, it is equally true that this activity must be balanced with measures to limit unsustainability in the medium and long term. Following this line of thought, it is interesting to consider whether proper water management in these environments could have positive consequences for the bottom line of economic activities related to tourism, either through cost savings or because the associated image could affect the level and characteristics of demand. Conversely, we will examine whether efficient management of tourism activities could positively impact water availability in environments, such as the Canary Islands, where this resource is particularly scarce. In this context, this project will attempt to answer these questions by analyzing the potential impacts of a strategy to improve water management efficiency in the tourism sector and, conversely, the extent to which a strategy based on hydrological sustainability in tourism could affect water availability, both in terms of quantity and quality. It is essential to bear in mind that analyzing the tourism sector in the Canary Islands is particularly complex due to its fragmentation into seven island areas with very distinct characteristics. This fragmentation generates a vast array of micro-destinations with different circumstances and, consequently, different challenges. Therefore, the study will focus on the province of Santa Cruz de Tenerife, and specifically on the island of Tenerife. The objectives of this project are: 1. To analyze current water management practices in tourism-related activities, considering their social, environmental, and economic dimensions. 2. To propose a future action strategy centered on ecological innovation as the only way to guarantee the sustainable growth of this sector. 3. To propose indicators and metrics for evaluating the actions implemented according to the proposed plan. To achieve these objectives, the project will be carried out in four phases: – Phase 1: Diagnosis of water consumption and management in the tourism sector. The aim is to diagnose water consumption on the island of Tenerife, primarily through primary sources and surveys. This first phase is the most complex, as it is not easy to find regional statistics related to water consumption in the tourism sector. Analyzing the Spanish case specifically, it is observed that water consumption estimates do not distinguish between permanent residents, tourists, or commercial, industrial, and tourism activities, but rather differentiate only between household consumption and other economic sectors. This phase is expected to take eight months to complete. – Phase 2: Analysis of the environmental, social, and economic impact of the actions identified in the previous phase. In this case, we will draw on impact analysis studies applied to other sectors to design and develop a specific tool for the tourism sector. Our objective is to propose a dashboard that allows for a quick analysis of the implications of water consumption and management within the tourism sector. This phase is expected to take six months. – Phase 3: Design and development of a proposed action plan for water management, with a particular focus on the tourism sector. This phase aims to analyze best practices developed in other sectors and/or geographical locations in order to complete a strategic proposal that provides a framework for action within the tourism sector. The estimated time for this phase is 4 months. – Phase 4: Compilation and dissemination of results. In this final phase, a comprehensive manual will be produced, covering the main aspects related to the execution of this project. Additionally, at least four scientific articles, suitable for publication in high-impact journals, will be written to contribute scientific value to this area of specialization. Furthermore, the main results obtained from this project will be presented at four scientific conferences. The estimated time for this final phase is 4 months. The estimated time required for each phase of the research should be supplemented by two months for the specific design of the research and the data collection tool. We are aware that this is an ambitious project, given the limited research conducted on water as a social, environmental, and economic resource, particularly in the tourism sector. However, we are convinced of the need to dedicate resources to this area to ensure the sustainable development of an island region characterized by water scarcity, such as the province of Santa Cruz de Tenerife. The results of this study can be extrapolated to other regions with similar challenges.
