James (Jim) Pizzuto '75 will present "The Essential Role of Geology in Sustainable Watershed Management" on Friday, Nov. 8 at 3:30 p.m. in Olin Hall 149. Pizzuto, the Bernstein Geologist-In-Residence, is a professor of geology at the University of Delaware College of Earth, Ocean and Environment. His presentation is free and open to the public.
Most watersheds in the U.S. are no longer entirely natural systems, but rather reflect centuries of human impacts, many of which have impaired the valuable ecosystem services that watersheds provide. Based on geologic studies of mid-Atlantic rivers, Pizzuto will argue that restoring watershed ecosystems requires a new discipline of geoengineering, guided by a new ethos governing our relationship with nature. His studies of Chesapeake Bay restoration and industrial mercury pollution suggest that these problems can only be solved when watershed management recognizes the long timescales (millennia!) of watershed processes.
Pizzuto explains, "While these ideas are familiar to geologists, they challenge the imagination of policy wonks and the electorate. Furthermore, because scientific knowledge is never complete, science is poorly suited to guide these efforts. Rather, a new marriage of science, engineering, ethics, and values is needed."
