The Ecology, Economics, and Management Process for Nonpoint Pollution

Carpenter dedicated his Pew Fellowship to a major outreach program on nonpoint pollution of surface waters which involves several initiatives. The first has been a review of the natural science of nonpoint pollution and an economic analysis showing that phosphorous input targets should be reduced substantially below targets calculated by current standard models in order to achieve maximum economic benefit of watershed management. The results of the natural science review have been published and distributed in a technical report, a popular article and a color brochure.

Carpenter also has developed computer games to teach citizens about the ecology, economics and management process for nonpoint pollution. Part of the research to create the games included a detailed analysis of the phosphorous cycle of Lake Mendota and its watershed which provides background data for the computer simulations.

Carpenter also calculated a phosphorous budget for global agriculture which shows that overfertilization has increased phosphorous content of the world's agricultural soils by about 25 percent since 1960. This has devastating consequences for the water quality of lakes, reservoirs, rivers and estuaries. Carpenter's goal has been to use these data to publicize the implications for water quality globally.

During his fellowship, Carpenter launched the journal Ecosystems which is produced in collaboration with the Ecological Society of America, to communicate to a larger audience the values, functions and interactions of ecosystems. He also leveraged additional funding of $2.5 million from the National Science Foundation in a five-year grant to launch a major training program integrating social and natural sciences for sustainable management of freshwater systems.

Biography

Stephen Carpenter's primary issue area is freshwater ecosystem management. His recent work has focused on the economic and ecological feedback between humans and the world's watersheds. In particular, he has found that present ecosystem management of lake districts incorporates little explicit economic information about the environmental consequences of human actions.

Carpenter was a leader in the effort to develop a National Center for Ecological Synthesis which opened in 1995 in California. The center takes existing data needed for conservation and management decisions and converts the information into usable forms for sound, science-based policy development.
