In this paper, we explore the following questions： How has watershed management evolved？ What new tools are available and how can they be integrated into sustainable watershed management？ To address these questions, we discuss the process of developing integrated watershed management strategies for sustainable manage- ment through the incorporation of adaptive management techniques and traditional ecological knowledge. We address the numerous benefits from integration acrossdisciplines and jurisdictional boundaries, as well as the incorporation of technological advancements, such as remote sensing, GIS, big data, and multi-level social-eco- logical systems analysis, into watershed management strategies. We use three case studies from China, Europe, and Canada to review the success and failure of integrated watershed management in addressing different ecological, social, and economic dilemmas in geographically diverse locations. Although progress has been made in watershed management strategies, there are still numerous issues impeding successful management outcomes; many of which can be remedied through holistic management approaches, incorporation of cutting-edge science and technology, and cross-jurisdictional coordination. We conclude by high- lighting that future watershed management will need to account for climate change impacts by employing techno- logical advancements and holistic, cross-disciplinary approaches to ensure watersheds continue to serve their ecological, social, and economic functions. We present three case studies in this paper as a valuable resource for scientists, resource managers, government agencies, and other stakeholders aiming to improve integrated watershed management strategies and more efficiently and successfully achieve ecological and socio-economic management objectives.展开更多

Water quality and associated economic, environmental and social values have improved dramatically since the 1950s when the lower portion of the river was declared a dead zone during parts of the summer due to excessive inputs of domestic and industrial waste. The question today is how to ensure that progress continues in the face of persistent and growing threats to water quality. Recognizing the challenges facing the watershed, over 40 of the leading conservation groups in this 13,000 square mile region are pursuing a 10-year strategic initiative focused on water quality through the Delaware River Watershed Initiative, a conservation program advancing a combination of place-based work in watershed protection, restoration, education, collaboration and innovation through collective impact. This paper serves as an invitation for broader strategic involvement to accelerate watershed protection and restoration;it also is a springboard for stakeholders to set an agenda for ensuring that the Delaware River watershed delivers clean water for humans, plants and animals. The paper identifies eight “clusters” of sub-watersheds, constituting approximately 25 percent of the total Delaware Basin, where analysis has shown that investment in water quality could deliver significant returns. Diverse geology, land use, development patterns, population density and en-vironmental stressors are present throughout these sub-watershed clusters. Focusing conservation actions in these places contributes directly to local water quality, and by fostering experimentation and innovation, it also cultivates a wide range of effective approaches for scaling up investment across the Delaware River watershed and beyond.
