Meeting Booklet 

Meeting Scope

This EGRD workshop aims to gain further understandings of the issues of the energy-water nexus and to highlight best practice and opportunities, including integrated systems, governance, regulations, and markets (national, inter-regional or inter-national). Participants will explore opportunities for addressing the energy-water nexus in order to inform more effective R&D planning and policies.


The workshop will result in a summary report that identifies challenges and opportunities of the water and energy nexus and present perspectives and best practice.

Target audience

In addition to EGRD members and national experts, we are seeking input from social scientists, RD&D decision-makers, strategic planners and programme managers from industry, academia, think tanks, national laboratories, NGOs and government. Participation is by invitation only.
