EcolChange seminar frenzy – three upcoming seminars this week

This week will take place three EcolChange seminars, all over the town. At first there is the seminar in the Chair of Crop Science and Plant Biology in the Estonian University of Life Sciences, and then in the University of Tartu – in the Department of Geography and in the Department of Botany.

Title of the talk: The Role of Wetlands in Mitigating Pollutants in Our Landscape and Globe

Time: Wednesday, 06. December 2017 at 16.15

Place: Tartu, Tartu, Vanemuise 46-327

Abstract:

The world is faced with unprecedented threats to our aquatic ecosystems from excessive nutrients caused especially by agricultural and urban runoff. More than 750 aquatic ecosystems suffer from degraded ecosystem services with impairments described as hypoxia, dead zones, and harmful algal blooms, most due to pollution caused by excessive nitrogen and phosphorus. And we have increased the atmospheric pool of carbon by 40% since industrial times leading to several impacts related to climate change.  At the same time, it has also been estimated that, on a global scale, we have lost half of our original wetlands to our current extent of 8 to 12 million km2, with most of that loss in the 20th century.  I am proposing here a sizeable increase in our wetland resources around the world to solve the diminishing wetland problem but with the strategic purpose of mitigating the excess phosphorus, nitrogen, and carbon in a sustainable fashion. Examples include minimizing phosphorus inflows to the Florida Everglades and Lake Erie in the Laurentian Great Lakes and reducing nitrogen fluxes by wetlands and riparian forests in Midwestern USA to reduce seasonal hypoxia in northern Gulf of Mexico.  Finally, wetlands and especially coastal wetlands are being proposed as carbon sinks through carbon sequestration to mitigate human-caused emissions of greenhouse gases. Our current approach for decreasing the nutrient saturation of our landscapes and aquatic ecosystems—defined as wetlaculture—will be introduced.
