Impact of Hydropower on River Biodiversity and Strategies for Recovery

Zhihai Yang

Abstract


Hydropower significantly contributes to global renewable energy but also poses serious challenges to river biodiversity. This paper
examines the ecological impacts of hydropower, such as changes in hydrological regimes, habitat fragmentation, migration barriers, and water
quality degradation. It also explores various recovery strategies, including environmental flow management, habitat restoration, fish passage
facilities, and community-based conservation initiatives. Case studies like the Elwha River restoration and the Aswan High Dam illustrate lessons learned and the necessity of integrating scientific, policy, and community efforts to sustain river ecosystems alongside hydropower development. This research underscores the balance needed between renewable energy benefits and ecological preservation.
