| Abstract: | Watershed management is an ever-evolving practice involving the management of land,water,biota,and other resources in a defined area for ecological,social,and economic purposes.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 management through the incorporation of adaptive management techniques and traditional ecological knowledge.We address the numerous benefits from integration across disciplines and jurisdictional boundaries,as well as the incorporation of technological advancements,such as remote sensing,GIS,big data,and multi-level social-ecological 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 highlighting that future watershed management will need to account for climate change impacts by employing technological 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. |
