Dr. Michael J. Puma
Affiliation: Columbia University
NASA Goddard Institute for Space Studies
New York, NY 10025 USA
Dr. Puma studies water, food, climate issues and global food security as well as systemic risk in the global food system. His work has contributed to the understanding of land-atmosphere interactions, especially the impacts of irrigation on temperature and precipitation. He is working to understand the limits to predictability for water and food systems, because each needs a fundamentally different approach and is sensitive to non-predictable extremes. He teaches courses at Columbia University on hydrology and water governance.
