Environment issues are widely recognized as potential causes for instability and conflict. Recognizing these dangers, NATO’s Committee on the Challenges of Modern Society (CCMS) directed a Pilot Study, “Environment and Security in an International Context,” to analyze the relationship between environmental change and security in an international, regional, and global level. The main goal of the study is to elaborate conclusions and recommendations to enhance environmental aspects in security deliberations, and to include security considerations in national and international environmental policies and instruments.
