Water policies around the world are in urgent need of reform. Despite improvements in some sectors and countries, progress on meeting national, regional and international goals for managing and securing access to water for all has been uneven. Rallying policymakers around a positive water reform agenda needs to be a high priority and calls for strong political commitment and leadership. This report on Meeting the Water Reform Challenge brings together key insights from recent OECD work and identifies the priority areas where governments need to focus their reform efforts. It calls for governments to focus on getting the basics of water policy right. Sustainable financing, effective governance, and coherence between water and sectoral policies are the building blocks of successful reform.
