Bronson Griscom

Director, Forest Carbon Science

I serve as Director of Forest Carbon Science for the Climate Team at The Nature Conservancy (TNC). Our research measures the success of TNC’s tropical forest conservation programs in Indonesia, Brazil, and Mexico in counter-acting climate change.  Our research improves the design of conservation strategies so that they are “climate smart.”

For example, we developed a method for measuring the emissions performance of commercial logging in Borneo, and proposed a form of Reduced Impact Logging designed to avoid Carbon emissions (RIL-C). We are now building these approaches into a Verified Carbon Standard (VCS) methodology for validating RIL-C emissions reduction across the tropics. See this blog for more on RIL-C, or this one for my thoughts on scaling up to achieve “climate smart forestry.”

Other lines of research include,

(i) forest biomass mapping integrating satellite, aerial lidar, and field data. We are building on this work to map mature forests with particularly high conservation value.

(ii) climate smart cacao agroforestry systems, that maintain cacao yield while maximizing environmental and social benefits,

(iii) analysis of alternative methods for setting robust reference emissions levels for REDD+ initiatives.

Prior to joining TNC, I led a successful effort at the U.S. Department of State to make climate change funding available for REDD initiatives through the Global Environmental Facility (GEF). Before that I coordinated an EPA-funded research program to prioritize watershed conservation and restoration efforts in the Mid-Atlantic Highlands. I completed a Ph.D. in tropical forest ecology from the Yale School of Forestry and Environmental Studies in 2003, and prior to that a M.Sc. from New York University in plant genetics and conservation.
