This course will consider the impacts of climate change and resulting resource scarcities on international peace and security. It will identify the likely environmental impacts of climate change - rising sea levels, prolonged droughts, desertification, etc. - and consider how they will heighten the risk of internal and international discord and conflict. It will also consider actions that can be taken by governmental and non-governmental organizations to reduce the risk of disorder and conflict arising from climate change and resource scarcity. Students will read and discuss recent UN and related studies on these problems, and conduct individual or team research on a particular aspect of the larger problem. The course will involve lectures, class discussion, student presentations, and in-depth student research.
