Marcia DeLonge

Sr. Scientist, Food and Environment
Marcia DeLonge

Marcia DeLonge is a senior scientist in the Food & Environment Program at the Union of Concerned Scientists (UCS). Dr. DeLonge conducts scientific research and analyses identifying practices that lead to healthy, sustainable food and farming systems. Her work seeks viable opportunities within agriculture to both adapt to and mitigate climate change.

Before joining UCS, Dr. DeLonge was a postdoctoral scholar at the University of California, Berkeley, in the Department of Environmental Science, Policy, and Management. She worked on a multi-stakeholder project that combined agriculture and climate science by seeking climate change solutions on grazing lands. Her field work and life cycle modeling helped reveal the potential for compost applications to promote sustainable agriculture while mitigating climate change.

Dr. DeLonge has a Ph.D. and M.S. in environmental science from the University of Virginia, where she developed expertise in atmospheric science, hydrology, ecosystem science, and numerical modeling. She also earned a B.A. in environmental science from Northwestern University.
