<Planning and Management of Lakes and Reservoirs:
An Integrated Approach to Eutrophication
Abridged Version- A Student's Guide>

Chapter 6. POLICY, LEGAL AND INSTITUTIONAL FRAMEWORK

Introduction

Anthropogenic eutrophication of lakes and reservoirs usually results from human intervention in the watershed. The effects of human intervention includes increased loading of nutrients and other pollutants, and the alteration of physical and biogeochemical conditions in the drainage and lake basin. Eutrophication management focuses on the prevention and reduction of pollution from point and non-point (or diffuse) sources as well as measures within the lakes and reservoirs. While end-of-the-pipe technologies may be suitable to mitigate point sources, control of non-point sources, as well as the implementation of waste reduction measures and within lake remediation, require a comprehensive approach to water resources management.

The effective implementation of sound water management practices for eutrophication control implies simultaneous incorporation of top-down and bottom-up measures within the social system. Top-down measures involve the incorporation of environmental concerns into policies, planning, and decision-making at the highest level. Initiatives then pass into the institutional and regulatory frameworks of jurisdictions sharing the watershed. Bottom-up measures involve incorporating environmental concerns into civil society at the community level.
