Gerhard Herzberg Lecture

The Herzberg Lectures are held annually in honour of Gerhard Herzberg, a former Chancellor of Carleton University and recipient of the 1971 Nobel Prize for Chemistry. The lectures emphasize the relationship between science and society and seek to address an aspect of science which has a pronounced impact on our daily lives. 

The Herzberg Lectures are free and open to the public.

Wetlands photo with text-75.jpg

The world is faced with unprecedented threats to our aquatic ecosystems from excessive nutrients, particularly nitrogen and phosphorus, caused by agricultural and urban runoff and discharges.

In addition carbon is increasing in our atmosphere leading to climate shifts and rising sea levels. In the meantime, it has been estimated that, on a global scale, we have lost half of our original wetlands, most of that loss in the 20th century. I am proposing here a significant increase in our wetland resources around the world, solving the diminishing wetland habitat loss problem, but with the strategic purpose of minimizing the excess phosphorus, nitrogen in our lakes, rivers and estuaries and sequestering carbon in our atmosphere, both in a sustainable fashion. Examples presented will include: 1. attempts to minimize phosphorus inflows to the Florida Everglades with wetlands to protect both the Florida Everglades and Florida’s coastlines; 2. a proposal to restore the Black Swamp in NW Ohio to minimize eutrophication of Lake Erie in the Laurentian Great Lakes; 3.
wetland and bottomland riparian forest restoration in the U.S. Midwest to mitigate a 15,000 km2 hypoxia in the Gulf of Mexico: and 4. conservation and enhancement of tidal mangroves for their capacity to sequester carbon from the atmosphere with fewer emissions of methane than freshwater wetlands (blue carbon).
