This document discusses a project to address unsustainable groundwater use in the MENA region. It aims to systematically take stock of past groundwater governance experiences at the global, regional and local levels, including laws, regulations, community actions and institutional structures, and their effectiveness in different contexts. The project will support sharing ideas across MENA countries and other regions, while contextualizing solutions for each state. It involves six countries - Oman, Yemen, Jordan, Abu Dhabi, Tunisia and Lebanon - which offer a diversity of experiences in dealing with groundwater issues, both long-standing and more recent.
