Climate change and ecological collapse posed growing threats to people, states, and economies. It has been estimated that a 1-degree increase in global temperatures would require a near tripling in disaster response spending over 15 years just to match the current level of humanitarian coverage. However, it has also been shown some truth to the old proverb about ounces of prevention: for every dollar spent on reducing vulnerability to disaster, two dollars are avoided on future damages. This course is designed to introduce students to the basic theories, strategies and best practices for reducing the risk of hazards and technological disasters in an age of environmental and political instability. Along the way, it will encourage students to think critically about the so-called “triple nexus” between humanitarianism, development, and peacebuilding.
