The second edition of the Caucasus Environment Outlook (CEO-2) emphasizes in its nine chapters the importance of regional environmental monitoring through a participatory and consultative approach. It explores the latest regional developments and environmental assessments in terms of population, urbanization, economic development, climate change, land cover, biodiversity, air quality, freshwater and cross-cutting issues, illustrating how policies can influence environmental outcomes and how environmental changes can, in turn, shape policy. Applying the methodology of the Global Environment Outlook, the CEO-2 contains a wealth of information, maps and tables and is unique in involving researchers and the academic community from across the six Caucasus countries in its publication. The analysis of environmental trends considers various social, cultural, economic, environmental, and political factors, offering a cross-sectoral perspective.”
