Prof. Orions on Ecological Indicators

2003-03-24 - 2003-03-24

Prof. Gordon Orions will on March 24, 2003, hold the seminar "Ecological Indicators. The Value of Small Numbers".

Economic indicators attract considerable attention from all segments of human society but ecological indicators are routinely ignored. In part the neglect stems from the superabundance of ecological indicators.

Guided by the hypothesis that the value of any ecological indicator is inversely proportional to the number of indicators with which it competes, the U. S. National Research Council and the John Heinz Center have struggled to craft a few indicators that capture components of environmental status and trends that might have the ability to influence public policy.

Will these efforts succeed? What needs to be done to achieve success?
