The past century of exponential population growth, infrastructure development, and resource uses has stressed nature’s systems to dangerous levels. A particularly ominous threat faces us from the loss of cultural and biological diversity, and the associated challenges posed by severely disrupted climate systems. This Gallatin practicum will develop a 21st Century conservation toolkit and cutting edge strategies to reduce global threats to biological and cultural diversity. We will use tools from the biological, physical, and social sciences to determine the cause, magnitude, and urgency of threats. Students will then use the results from these scientific approaches to develop practical conservation solutions that can be applied on the ground. Students will work in teams to select a site-based project from a menu of project options and use tools from anthropology, social psychology, economics, biology, communications and the arts to generate practical and achievable solutions to these risks and threats.
