Conversion of grasslands to agricultural fields across Southeastern Minnesota is increasing groundwater nitrate contamination in private drinking water wells according to a new study by researchers with the University of Minnesota and the Natural Capital Project.
Writing in the journal Environmental Research Letters, the researchers outline the economic costs associated with groundwater pollution along with threats to overall water quality and ecosystem services.
“Households can dig a new well, purchase bottled water, or install a home nitrate-removal system, but dealing with a contaminated well is expensive and these costs are typically born entirely by private households,” said Bonnie Keeler, lead author and lead scientist with the Natural Capital Project at the University of Minnesota’s Institute on the Environment. “We found evidence that recent trends in grassland loss to agriculture between 2007 and 2012 are likely to increase the future number of contaminated wells by 45%, leading to millions of dollars in lost income and remediation costs for private households.”
Policy makers, land managers, and other stakeholders confront a dizzying array of environmental decisions. How do we best manage our natural resources? Where should we invest in conservation? Do we need stricter regulation of development or industry?
The Natural Capital Project, a core program of the Institute on the Environment, develops innovative tools and approaches to inform these important questions. Starting this year, the Minnesota team will add three full-time research positions — a lead scientist, an ecologist and an economist. The growing NatCap presence at IonE will enhance the program’s ability to meet increasing demand for data and tools that quantify the values of natural capital. Continue reading
Did you know that nearly half the American food supply gets neglected or outright rejected?
Love Letter to Food, the latest video from MinuteEarth, laments the myriad abuses suffered by food because the convenience of wasting it outweighs the cost. Continue reading
People of color in the U.S. are exposed to 38 percent more nitrogen dioxide air pollution in the neighborhoods in which they live than are white people, according to new research from the University of Minnesota. The exposure they receive results in approximately 7,000 heart-related deaths per year.
U of M Instititute on the Environment resident fellows Julian Marshall and Dylan Millet and fellow researcher Lara Clark compared U.S. Census data and nitrogen dioxide levels in cities across the country and found that, irrespective of income, nonwhites had higher average exposure to nitrogen dioxide than whites. The findings received extensive coverage in the media this past week. Continue reading
Mining near sensitive ecosystems is one of the hottest natural resource debates, pitting economic and environmental values against each other. As the controversy surrounding mining in Minnesota continues, opponents may want to take a few notes from one of the nation’s largest, successful anti-mining campaigns to date.
Mike Clark, former executive director of the Greater Yellowstone Coalition, shared his experience fighting the New World mining project outside the nation’s largest national park in the 1980s and 1990s in his Frontiers in the Environment lecture Wednesday, April 9 on the University of Minnesota’s St. Paul campus.
In “Yellowstone: More Valuable Than Gold,” Clark discussed what makes the park and surrounding landscape so valuable and why that usually leads to conflict.
When you think of the economy, chances are the “green” that comes to mind is money, not nature. But what if there wwere truly a green economy – one that accounts for the value of the environment in economic decision-making?
That was the topic of last week’s Frontiers in the Environment lecture presented by Steve Polasky, an IonE resident fellow and Regents professor of applied economics. Polasky delivered his speech, “What IS the Green Economy? And How Do We Get One?” Feb. 12 at the University of Minnesota in St. Paul. While economics and the environment do not always seem to go hand in hand, it was his love for nature that pushed Polasky to pursue economics.
There you are, hunkered over your sink, hands wrist-deep in hot water, swiping suds over food-crusted dinner plates. That squishy, soapy thing that’s helping you do so many daily chores…ever wonder where its life began and where it will end?
That sponge, like everything on the planet, has a life cycle, composed of all the materials and energy that brought it to your sink and all the tasks it will help you complete until you’ve squeezed the last bit of work from it and tossed it into the trash. Continue reading
Universities, religious institutions, and even local governments around the globe are weighing the pros and cons of divestment – a climate change mitigation strategy that focuses on phasing out endowment investments in fossil fuel companies.
Matthew Fitzmaurice, founder and managing partner of AWJ Capital Partners LLC, explained the opportunities and shortcomings of divestment in his Frontiers in the Environment presentation Nov. 6.
In “Divestment: A Call to Arms vs. Sustainable Investing: A Catalyst for Global Change,” Fitzmaurice argued that divestment, while a laudable goal, may not be realistic for institutions.
Do you know about the Water Framework Directive? It calls for all waters in the European Union to be managed as river basins and for those river basins to be brought up to “good status.” That’s tremendous – a really forward-looking way to think about managing water. But as you can surely imagine, it’s also quite a task to implement!
I was lucky enough to work with the RISKBASE group during 2009-2010 to help develop risk-based approaches for managers to guide river basins to good status. I’m not an expert in risk, nor an expert about European river basins, but I was really excited to get involved. This had the potential to bring biophysical science together with new management approaches to actually solve problems. Continue reading
Natural Capital Project director Mary Ruckelshaus, former lead scientist Heather Tallis, and software head Rich Sharp got a chance to share the NatCap message with a global audience last week through a presentation to the Commonwealth Club of California, the nation’s premier public affairs forum.
