“…While these scenarios are simplistic and applied uniformly to all dams, they provide a useful envelope for estimating the range of potential impacts from dramatically changing dam operation rules. Leveraging an established methodology that isolates and scores the ecosystem risks and benefits of changing water landscapes 33 , 37 , 38 , we then used the social-ecological framework of the Freshwater Health Index 32 to compare the results of these scenarios and their relative impacts on key indicators of ecological health and human well-being.…”

Managing transboundary river basins requires balancing tradeoffs of sustainable water use and coping with climate uncertainty. We demonstrate an integrated approach to exploring these issues through the lens of a social-ecological system, combining remote and in-situ earth observations, hydrologic and climate models, and social surveys. Specifically, we examine how climate change and dam development could impact the Se Kong, Se San and Sre Pok rivers in the Mekong region. We find that climate change will lead to increased precipitation, necessitating a shift in dam operations, from maintaining low flows to reducing flood hazards. We also find that existing water governance systems in Laos, Vietnam, and Cambodia are ill-prepared to address the problem. We conclude that the solution space for addressing these complex issues will be highly constrained unless major deficiencies in transboundary water governance, strategic planning, financial capacity, information sharing, and law enforcement are remedied in the next decades.

“…However, with few exceptions, such as the European Union's Water Framework Directive, decision-makers are at an early stage in developing and integrating ecosystem services into water resource management. In apply this indicator framework under FHI (basins from Asia, Africa, and Latin America) we have found that most stakeholders, whilst familiar with the concept of water ecosystem services, have considered them less often than the bio-physical or governance aspects of water management (Vollmer et al 2018;Bezerra et al 2021;Souter et al 2020;Wen et al 2020). Furthermore, the need for monitoring and management of water ecosystem services is not yet legislated in many jurisdictions (cf Liu et al 2019).…”

Natural ecosystems are fundamental to local water cycles and the water ecosystem services that humans enjoy, such as water provision, outdoor recreation, and flood protection. However, integrating ecosystem services into water resources management requires that they be acknowledged, quantified, and communicated to decision-makers. We present an indicator framework that incorporates the supply of, and demand for, water ecosystem services. This provides an initial diagnostic for water resource managers and a mechanism for evaluating tradeoffs through future scenarios. Building on a risk assessment framework, we present a three-tiered indicator for measuring where demand exceeds the supply of services, addressing the scope (spatial extent), frequency, and amplitude for which objectives (service delivery) are not met. The Ecosystem Service Indicator is measured on a 0–100 scale, which encompasses none to total service delivery. We demonstrate the framework and its applicability to a variety of services and data sources (e.g., monitoring stations, statistical yearbooks, modeled datasets) from case studies in China and Southeast Asia. We evaluate the sensitivity of the indicator scores to varying levels data and three methods of calculation using a simulated test dataset. Our indicator framework is conceptually simple, robust, and flexible enough to offer a starting point for decision-makers and to accommodate the evolution and expansion of tools, models and data sources used to measure and evaluate the value of water ecosystem services.

“…The FHI frames freshwater ecosystems as dynamic social-ecological networks, with linkages and feedbacks that reveal human water needs and the ecological effects of using fresh water in a watershed. This focus on freshwater ecosystem health engages stakeholders and decision-makers (Vollmer et al 2020;Souter et al 2020;Wen et al, 2020). The FHI incorporates both supply and demand for water-related ecosystem services, which diagnoses freshwater health for land and water resource managers and provides a mechanism for evaluating tradeoffs.…”

Natural ecosystems are fundamental to local water cycles and the water-related ecosystem services that humans enjoy, such as water provision and protection from natural hazards. However, integrating ecosystem services into water resources management requires that they be acknowledged, quantified, and communicated to decision makers. We present an indicator framework that incorporates the supply of, and demand for, freshwater-related ecosystem services, which provides an initial diagnostic for natural resource managers as well as a mechanism for evaluating tradeoffs through future scenarios. Building on a risk assessment framework, we present a three-tiered indicator for measuring where demand exceeds supply of services, addressing the scope (spatial extent), frequency, and amplitude for which objectives (service delivery) are not met. The Ecosystem Service Indicator is presented on a scale of 0-100 which encompasses none to total service delivery. We demonstrate the framework and its applicability to a variety of services and data sources from case studies in China and the Lower Mekong region. We also evaluate the sensitivity of the indicator score derived from these methods, to communicate uncertainty. The proposed indicator framework is conceptually simple, robust, and flexible enough to accommodate the inevitable evolution and expansion of tools, models and data sources used to measure and evaluate the value of water-related ecosystem services.
