“…The Tagus river basin is the longest river in the Iberian peninsula and supplies water resources to approximately 15% of the Spanish and 30% of the Portuguese population (Lobanova et al, 2017). The increasing water demand and the high number of dams regulating the river led to water scarcity problems and poor ecological status in some water bodies (Sondermann and de Oliveira, 2021). The Segura basin is one of the most water-stressed regions in the Mediterranean basin (Aldaya et al, 2019).…”

“…The model validation was carried out by adjusting the reservoir operating rules and the water allocation policies to the historical records of inflow, outflow and stored volume in reservoirs and the historical streamflow in monitoring sites while ensuring high-reliability levels of water supply. As the management policies implemented in the model simplify a complex decision-making process, the results are associated with some uncertainty [32,33].…”

“…Lobanova et al [31] considered the entire river basin but focused their appraisal on the impacts of climate change on the river basin hydrology and hydropower production capability. Sondermann and Oliveira [32,33] studied the entire river basin and evaluated the basin's ability to satisfy current and future water demands on both sides of the border, assuming the historical water availability records and not considering climate change impacts. To quantify water scarcity and the basin ability to satisfy water demands, indicators such as the Water Exploitation Index Plus (WEI+) and water supply reliability, vulnerability, resilience, and sustainability were used.…”

In southern Europe, climate change is expected to aggravate water scarcity conditions and challenge current water management practices. The present paper evaluates the impacts of climate change in the highly regulated Tagus River basin and assesses various adaptation options, quantifying the effort needed to maintain the ability to sustain current water uses. A water management and allocation model covering surface and groundwater resources is used to evaluate available and renewable water resources for different climate scenarios. Additionally, the Water Exploitation Index Plus (WEI+) and water supply reliability criteria are used to quantify water scarcity and the ability to satisfy water demands, respectively. The results show that climate change will significantly change the stream flow regime and reduce water availability in the Tagus River basin, but the existing reservoir infrastructure will alleviate some of these impacts, especially in the dry half-year. Until the end of the century, water scarcity levels, measured by annual WEI+, are expected to increase in the Tagus River basin from 0.46 to 0.52 or 0.62, respectively under two Representative Concentration Pathways (RCP 4.5 or RCP 8.5). The benefits of streamflow regulation vary with the hydrological regimen, the current degree of water use and the role of groundwater resources to meet demand. The benefits of streamflow regulation are also dependent on the environmental flow requirements that will be adopted in the future. A reduction of water consumption for irrigation by 25% to 40% will significantly improve the Tagus River system performance and maintain the current scarcity situation in the future, under the expected scenarios of climate change.

Water‐abundant regions face challenges due to urbanization and development, which pose threats to local water networks and the environment. Fragmented water network management and administrative boundaries hinder cross‐administrative collaboration and ecological conservation. This study presents a framework centered around the “Watertown Hub” concept, which focuses on integrated ecological and green development, fostering multifunctional, shared spaces for coordinated management in the Watertown region of the Yangtze River Delta, China. By leveraging landscape infrastructure and ecological sensitivity assessment, shared spaces are established beyond administrative boundaries, promoting cross‐administrative coordination, management, and resource integration. The approach effectively balances the protection of basin ecology and economic development, mitigates water system fragmentation, and addresses environmental concerns. It enhances regional communication, connectivity, and sustainability. Although the focus is on China's Jiangnan region, this research provides insights applicable to other water‐rich areas in South Asia and beyond, fostering cross‐administrative ecological coordination and sustainable development amidst urbanization pressures.
