Using the Freshwater Health Index to Assess Hydropower Development Scenarios in the Sesan, Srepok and Sekong River Basin

摘要: Sustainable water resource management is a wicked problem, fraught with uncertainties, an indeterminate scope, and divergent social values interests among stakeholders. To facilitate better of Southeast Asia’s transboundary Sesan, Sekong Srepok (3S) River basin, we used the Freshwater Health Index (FHI) to diagnose basin’s current likely future level freshwater health. We conditions for December 2016 as baseline, where Ecosystem Vitality Services scored 66 80, respectively, out possible 100, whilst Governance & Stakeholders 43. Thus, 3S provided range desired ecosystem services, but there were signs environmental stress well undeveloped governance systems limited stakeholder engagement. also modelled four hydropower development scenarios found that increasing reduced scores subset indicators. This compromised ability provide its services. The FHI helped identify data deficiencies, illuminated important dynamics, made ecosystem–human–water dynamics more understandable stakeholders, examined long-term basin.
