The OECD has been working on water policy reform in the countries of Eastern Europe, the Caucasus and Central Asia for over 20 years. Three of the countries within the region, Georgia, the Republic of Moldova and Ukraine have signed Association Agreements with the European Union.

Since the 1990’s, the countries of Eastern Europe, the Caucasus and Central Asia (EECCA) have made great progress in pursuing economic development that is also environmentally sustainable. The countries, in collaboration with the GREEN Action Task Force hosted by the OECD, has developed a number of policies aiming to improve environmental quality and social well-being, while creating opportunities for strong economic growth and decent jobs in the region.

This publication examines the critical issues surrounding water security (water shortage, water excess, inadequate water quality, the resilience of freshwater systems), providing a rationale for a risk-based approach and the management of trade-offs between water and other policies.

The studies contained in this volume demonstrate that despite the economic crisis, there still is much potential in this region and that the measures that need to be taken to realise that potential are feasible and affordable.

Groundwater allocation determines who is able to use groundwater resources, how, when and where. It directly affects the value (economic, ecological, socio-cultural) that individuals and society obtain from groundwater, today and in the future. Building on the 2015 OECD publication Water Resources Allocation: Sharing Risks and Opportunities, this report focuses on groundwater and how its allocation can be improved in terms of economic efficiency, environmental effectiveness and social equity. Drawing on an analysis of groundwater's distinctive features and nine case studies of groundwater allocation in a range of countries, the report provides practical policy guidance for groundwater allocation in the form of a "health check". This health check can be used to assess the performance of current arrangements and manage the transition towards improved allocation.
