Honey Bee Pollination Crisis

Professor Claire Kremen at the Commonwealth Club

Monoculture farming leaves us highly dependent on honey bees, whose pollination affects 75 percent of fruits and vegetables and 30 percent of all food production. However, managed hives are being wiped out by colony collapse disorder at an alarming rate.

Professor Claire Kremen discusses how wild bees can boost the effectiveness of managed hives and play a critical role in pollinating the crops that keep California's economy humming.

Bio
Claire Kremen is a conservation biologist whose applied research advances the fields of ecology, biodiversity, and agriculture. As a leader of a conservation planning initiative in Madagascar, Kremen has used adaptive management and predictive mapping to design and establish protected and multiple-use areas in Masoala National Park, Madagascar’s largest nature reserve. Her current work in Madagascar includes forecasting deforestation and its impact on species distribution and development of a web-based repository that will provide researchers with up-to-date biodiversity data and analytical tools needed for conservation planning and monitoring. In other research in the U.S., at the intersection of agriculture and biodiversity, Kremen explores the behavior of diverse native pollinators (primarily bees) and the environments that sustain them. By analyzing the behavior patterns of bees, Kremen investigates an often overlooked but critical component of the global food web, as more than half of all flowering agricultural crops involve natural pollinators. She measures several key variables, including geographic distribution of natural habitats, the diversity of insect pollinators, and the delivery of pollination services. Claire Kremen received a B.Sc. (1982) from Stanford University and a Ph.D. (1987) from Duke University. She is an assistant professor in the Department of Environmental Science, Policy, and Management at the University of California, Berkeley. From 2001 to 2005, she was an assistant professor in the Department of Ecology and Evolutionary Biology at Princeton University.
