“…In the north of the country, there is overexploitation by mining activities of fossil and nonrenewable groundwater resources (late Pleistocene and mid-Holocene mean ages; e.g., Viguier et al 2019 ). In the center and south of the country, conflict is related to several activities that have triggered surficial water and groundwater depletion—for instance, the interventions on rivers for hydroelectric generation, farming practices to produce avocados, and agricultural pollution from the fertiliser overuse (e.g., Bauer 2005 ; Fernández et al 2017 ; Taucare et al 2020 ; Barría et al 2021 ; Fuentes et al 2021 ; Madariaga et al 2021 ). The conflicts have arisen due to the allocation of water being conducted without a rigorous scientific and technical assessment, prioritizing the water supply instead of regulating the water demand.…”

Water scarcity is a critical issue worldwide, and Chile is no exception. Since 2010, Central Chile has been enduring an ongoing water crisis due to the coupled effects of a severe drought and the overuse of water resources, especially groundwater. Rural communities have been strongly impacted, mainly because wells from which drinking water is supplied show a dramatic drop in water levels, and some have even dried up. The water scarcity scenario requires the integration of actors and disciplines to increase awareness of groundwater; however, how to make this valuable element visible in society is an issue that remains open to debate. This paper describes and reflects on the process of making educational material about groundwater and water scarcity for children to promote public awareness. Based on transdisciplinary and co-designing processes, this work describes the social perceptions of groundwater among children and community leaders, as well as how scientific information and local knowledge of water scarcity could be integrated into a book for the young population. This research finds that educational projects on groundwater resources increase people’s awareness of the role of this hidden resource in the water cycle. Such projects encourage the creation of grounded and contextualised materials that incorporate the knowledge and experience already present in the communities, increasing public awareness of the role of groundwater and associated water scarcity issues, thereby integrating academia and society. This approach could be a tool to lay the foundations for successfully addressing the water crisis in Chile over generations.

“…Projections indicate that the situation will worsen in the future, as the ratio between total water withdrawals and available renewable surface water is expected to reach a value superior to 80% by 2040, and the country's water stress to be categorized extremely high, as a result of rising temperatures in critical regions and shifting precipitation patterns [ 194 ]. Trends illustrate that the level of 147 wells (72% of monitored wells) [ 191 ] and the level of streamflows in rivers [ 195 ] are decreasing. The main state agency designed to manage the country's water resources is the General Directorate of Waters (DGA, for its acronym in Spanish), which operates under the authority of the Ministry of Public Works.…”

“…Chile has seen consecutive droughts over the past 10 years (Fuentes and Fuster 2021), in Spain the total annual rainfall is declining (Ibáñez and Caiola 2013), and the Murray-Darling basin in Australia had the Millennium Drought (1997-2009) (Wheeler et al 2013). At the same time, these hotspots have effective acts and agreements that support sustainable use of water resources (water treatment 12%-50%, water rights 10%-69%, increased storage capacity 23%-60%).…”

Global freshwater resources are vital to humanity and Earth’s ecosystems, yet about one third of the global population is affected by water scarcity for at least one month per year. In these areas, the overuse of freshwater resources can lead to the threat of depletion, marking them as the global “water scarcity hotspots”. This study combines outputs from a global hydrological model (PCR-GLOBWB 2) with an extensive literature search to provide a comprehensive intercomparison of the key Drivers, Pressures, States, Impacts and Responses (DPSIR) that shape the water gap between water demand and availability at the most important water scarcity hotspots worldwide. Hydroclimatic change, population growth, and water use for the industrial, municipal and agricultural sectors are the most important driving and pressuring forces on the water gap, affecting both water quality and quantity. These Drivers and Pressures have been showing increasing trends at all hotspots, which is concerning for the future development of the water gap. Additionally, we identify and characterize seven clusters of hotspots based on shared DPSIR patterns, revealing their common mechanisms. Our work highlights the diversity of water scarcity related issues at hotspots, especially the variety of impacts involved and governmental responses in place. The results of our DPSIR analysis provide valuable insights for building causal networks representing water gap dynamics at the hotspots. They form a foundation for conceptual models that illuminate human-water interactions, trade-offs, and synergies at the hotspots, while guiding policymakers in addressing the multifaceted challenge of closing the water gap.
