Focus Session

River basin development

Understanding connectivity, cumulative impacts and improving trade-offs

Wednesday 15 May 2019 | 15:45-17:00 | room: Eiffel 1

Basin and regional-scale planning in hydropower development comprise not only the optimisation of energy systems but also broader environmental, social, water, food and climate change outcomes when managing hydropower in a river basin or regional context.

Successful river basin management involves a holistic approach which encourages cooperation among a diverse group of stakeholders in the utilisation of natural resources. The integrated management of reservoirs and multiple uses of water, institutional and regulatory agreements, as well as the integration between neighbouring countries, comprises different trade-off methodologies to manage a hydropower project at a system level.

Session objectives:

What are the upstream and downstream effects of hydropower facilities’ operational schemes and how do cumulative impacts influence decision making?

This session will discuss how the cumulative impacts of natural resources development in a basin can affect decision making. It will focus on the role that operation schemes of existing hydropower facilities have on trade-offs at the basin scale and long term impacts.

While significant work and research has been put on approaches at planning level, this session focuses on the upstream and downstream effects of operational schemes of hydropower facilities, and approaches for evaluating and managing positive and negative impacts.
