Marianne Krasny is professor and chair in the Department of Natural Resources, and Director of the Civic Ecology Lab, at Cornell University in Ithaca, New York.

She works with community-based organizations to examine how self-organized, environmental stewardship practices in cities contribute to ecosystem services, civic renewal, and social-ecological systems resilience.

She also directs the US Environmental Protection Agency’s national environmental education training programme.

Through this multi-collaborator initiative, Dr Krasny serves as a “scale-crossing broker” to foster exchange of ideas between an emerging group of urban environmental educators and the more established environmental education community, with the goal of redefining environmental education for an urban society.
