the management of water supply and quality in lakes, rivers, and reservoirs has proceeded largely on the basis of local rather than global considerations. high-quality freshwater resources are now in critically short supply, not only because of local problems such as over-irrigation and eutrophication, but also as a result of large-scale impacts such as climate effects on the hydrosphere. this book explores the dichotomy of global strategies (international and generic) versus local strategies (site-specific) for lake, river, and reservoir management, and presents a series of contrasting perspectives on topics that include monitoring, modeling, water treatment, eutrophication, and restoration. the final chapter integrates these perspectives and identifies strengths, weaknesses, and complementary aspects of the two approaches to help refine future strategies for the sustainable use of the worlds freshwater resources.
