As part of the Water Institute's WaterTalks lecture series, Alex Mayer, professor of civil and environmental engineering at Michigan Technological University, presents, "Developing the Great Lakes’ Blue Economy: Water productivity, water depletion, and virtual water trade in the Great Lakes basin."
Coffee and light refreshments provided.
Description
The Great Lakes basin hosts the world’s most abundant surface fresh water reserve, with the potential for the region to sustainably utilize its relative water wealth for economic benefit. We combine economic production and trade data sets with water consumption data and models of surface water depletion in the region to determine the virtual water imports and exports for the US portion of the basin.
Commercial water uses are the most productive, as measured by the ratio of trade to water use for the sector, with thermoelectric, mining, and agricultural water uses in the lowest tier of water productivity. Surprisingly for such a water-abundant economy, the region is a net importer of water-derived goods and services.
We find that, on average, the current economy does not create significant impacts on surface waters, but there is some risk that unregulated large water uses can create environmental flow impacts if they are developed in the wrong locations. This finding, combined with the abundance of surface water, suggests that the region’s water-based economy has room to grow in the 21st century.
