Today, more and more freshwater bodies have become polluted by nutrients originating from agricultural, domestic and industrial sources. This situation causes these freshwater bodies to become eutrophied. In an effort to prevent this problem, significant financial resources have been invested in expensive infrastructure and equipment, yet the situation is worsening. Furthermore, there has been a misconception that the only way to prevent the problem is through the use of technology. Technology can assist in this endeavor, but it is not the only answer.

This Students Guide deals with the eutrophication of lakes and reservoirs by considering its origins, consequences, solutions, and prognoses under an integrated approach. The objective is to assist local authorities in their effort to prevent, reduce, and control the eutrophication of lakes and reservoirs through the application of sound management practices. This publication outlines a new approach to water resources management, emphasizing the need to integrate and solve simultaneously the social, cultural, economic, environmental and other problems associated with eutrophication. The watershed approach is highlighted as a strategy to be adopted in the successful management of water quality in lakes and reservoirs.
