Stakeholder evaluation of the feasibility of watershed management alternatives, using Integrated Lake Basin Management principles

摘要

Containing more than 90% of the liquid fresh water on our planet's surface, lakes are used for a wide range of human needs. Managing them for sustainable use also requires consideration of a multitude of scientific, socioeconomic and governance issues. Integrated Lake Basin Management (ILBM) is a comprehensive approach for achieving sustainable management of lakes and reservoirs through gradual, continuous and holistic improvement of basin governance, involving sustained efforts for improvement of six governance 'pillars' (Policy; Institutions: Stakeholders; Knowledge; Technology; Finances). This study demonstrates that ILBM is applicable not only to lentic water systems (lakes, reservoirs), but also to the upstream and downstream water systems (rivers, tributaries) of which they are a part. Two watersheds in eastern Pennsylvania (USA), designated as 'Critical Water Planning Areas,' are used as a case study for this application, with a focus on the ILBM Stakeholder pillar. The primary objective was to rank the feasibility of alternative management options for these watersheds on the basis of watershed stakeholder perceptions and discussions. The results of this process and the analyses undertaken in this study are discussed, including the management options ultimately identified, the lessons learned in the evaluation process, and means for improving the process for future evaluations.
