Ecological economist to speak Aug. 19
Sunday, August 2, 2009
Robert Costanza is a leading scholar in the growing field of ecological economics.
The researcher who helped put a dollar figure on the world's ecosystems is coming to campus.
Robert Costanza, a Pew scholar, Kellogg scholar and director of the Gund Institute for Ecological Economics at the University of Vermont, is scheduled to speak 9 a.m. Aug. 19 in Stewart Hall's Ritsche Auditorium. A question-and-answer session will follow.
Costanza's presentation will keynote Convocation 2009, St. Cloud State University's four-day assembly of employees, ideas and information. The leading theme of this year's convocation is environmental sustainability.
In 1997, Costanza and 12 scholars from around the world published an article in the journal Nature that valued the world's ecosystems:
The services of ecological systems and the natural capital stocks that produce them are critical to the functioning of the Earth’s life-support system. They contribute to human welfare, both directly and indirectly, and therefore represent part of the total economic value of the planet.We have estimated the current economic value of 17 ecosystem services for 16 biomes, based on published studies and a few original calculations. For the entire biosphere, the value (most of which is outside the market) is estimated to be in the range of US$16–54 trillion (1012) per year, with an average of US$33trillion per year. Because of the nature of the uncertainties, this must be considered a minimum estimate.
By comparison, global gross national product total is about $18 trillion per year.
