Analysing the security risks resulting from climate change is essential for effective policy-making. The Organization for Security Cooperation in Europe (OSCE) and the European Environment Agency (EEA) is running the joint project 'Security implications of climate change in the OSCE regions' with the aim of improving understanding of the links between global megatrends and environment, and the security of food, fuel and water in different regions. It also aims to enhance cooperation and networking among the main institutions addressing climate security issues. A participatory-based scenario-building approach was used as a tool to help explore the complex and uncertain impacts stemming from climate change. This brochure provides a project overview, which includes the results of workshops carried out so far.
