Innovative approach to depicting the balance between water use and supply offers unprecedented resolution and incorporates both seasonal and dry-year data into a single global snapshot
MINNEAPOLIS/ST. PAUL (1/20/16) Water is essential to human well-being, yet reports of water shortages surface daily. Now, thanks to a team of global water experts, planning for water development and use just took a giant leap forward.
Researchers from the University of Minnesota Institute on the Environment, The Nature Conservancy, the Global Water Policy Project and the Center for Environmental Systems Research at the University of Kassel in Germany measured global water scarcity — the lack of sufficient water resources to meet demand — around the world at unprecedented resolution, incorporated seasonal and dry year shortages, and synthesized the information into a single, easily understandable global map that planners and policy-makers can use to improve access to water around the world. The result of their work was published today in the journal Elementa. Continue reading
Minnesota may be the land of 10,000 lakes, but clean water is becoming an increasingly scarce and valuable resource in the state. Does that matter? It does if we want to have enough water to support growing towns and cities, healthy ecosystems, and thriving industry and tourism sectors. An ambitious project underway at the University of Minnesota Institute on the Environment will assess the state of Minnesota’s water resources and provide cutting edge research and models to support more informed management of the state’s most valuable natural resource.

For the more than 200 attendees at a recent Minnesota Water Technology Summit, one thing was clear: Water is essential to life in Minnesota. “Water touches every aspect of our health, our recreation and our economic development,” said Bonnie Keeler, lead scientist of the Natural Capital Project and one of the panelists at the summit. “Water crises in California and elsewhere have added new urgency to understanding and anticipating water risks. Minnesota is a state rich in water resources, but even we are starting to see signs of stress in the form of polluted drinking water and depleted aquifers.” With this growing urgency comes increasing demand to understand the interactions between land management and water quality and to better quantify the benefits and costs of actions to protect and improve our water supply.

Water plays a crucial role in industry. It helps us generate electricity and mine for precious minerals, and supports numerous other functions that fuel the economy and provide society with the products and services essential to everyday life.
This week’s Frontiers talk featured Kate Brauman, lead scientist with IonE’s Global Water Initiative, and a panel of experts providing perspectives on the current state of groundwater resources. Joining her was Perry Jones, a hydrologist with the U.S. Geological Survey; Steve Polasky, IonE resident fellow, The Natural Capital Project lead, and professor in the College of Food, Agricultural and Natural Resource Sciences; and Sherry Enzler, general counsel for the Minnesota Department of Natural Resources. Here are five things we learned: Continue reading
In the second of this semester’s Frontiers in the Environment talks, IonE resident fellow Jonee Kulman Brigham, a visiting scholar in the College of Education and Human Development and Sustainable Design Program faculty member in the College of Design, taught us to question our relationship with natural resources and suggested ways we could rebuild our bond with the environment. Here are four things we learned:
Flickr-based study shows lakes with greater water quality receive more visits and users are willing to travel further to reach them
MINNEAPOLIS / ST. PAUL (2/2/15) – Think of the last time you planned a visit to a lake. Why did you choose the lake you did? Did you consider the quality of the water? The answers to these questions are critical to understanding how lake users make decisions about their recreation choices and the value society places on water resources.
New research published in Frontiers in Ecology and Evolution presents a novel approach to calculating the value of clean water. Analyzing photos posted to the online photo-sharing site Flickr, researchers at the Natural Capital Project and Iowa State University found Minnesota and Iowa lakes with greater water quality receive more visits than dirtier lakes, and that users are willing to travel farther to visit those clean, clear lakes.

Investing in watersheds makes sense. Keeping water clean and flowing at the source is cheaper and more reliable than fixing problems downstream. It’s something people have been doing for a long time and in lots of places. Where I grew up in California there are lots of water supply reservoirs that are pretty to look at but off limits for swimming. Across the country in the Catskills watershed, New York City is paying folks to replace septic systems and keep cattle away from riverbanks instead of building a water filtration plant. And we’ve seen some pretty bad things happen when watersheds aren’t managed right, such as streams turning brown from sediment or drying up all together.
So watershed investments are hot. All over the world, governments, non-profits and businesses are getting excited about the possibility of paying residents upstream to take actions that will keep clean water flowing consistently downstream. Continue reading
Nearly half of the world’s river volume is moderately to severely altered by dams today — a figure that could double by 2030 if all dams planned or under construction are completed, according to a report published online Jan. 6 in Environmental Research Letters.
An international team led by McGill University researchers overlaid data from nearly 6,500 existing large dams on a high-resolution map of the world’s rivers to create a detailed picture of how the dams alter the connections among rivers and their tributaries and interrupt natural fluctuations in water and sediment flowing downstream.

Editor’s note: IonE’s nearly 70 resident fellows — faculty with appointments throughout the University of Minnesota system who come together here to share ideas, inspiration and innovation across disciplinary boundaries — are among the shining stars of IonE’s signature approach to addressing global grand challenges. Here we interview IonE resident fellow Lawrence Wackett, Distinguished McKnight University Professor in the College of Biological Sciences. Let the conversation begin!
What project are you focused on now?
I am working on developing broad-based computer and practical methods for cleaning problem chemicals from the environment and setting up conditions whereby there is a business incentive to use the methods. The latter goal is typically outside the domain of academic research. But to really make an impact on the environment, I have come to believe we must go beyond publishing journal articles and op-ed pieces for people to read. It takes enormous creativity to think of environmental solutions that many people will be incentivized to implement. However, lasting environmental benefits will only accrue when business and the majority of citizens are driven by self-interest to eagerly adopt environmentally responsible practices. The carrot is more powerful than the stick! Continue reading
What would a clean water future look like for Minnesota? Bonnie Keeler, lead scientist for the Natural Capital Project at the University of Minnesota; Minnesota Pollution Control Agency commissioner John Linc Stein; and Deborah Swackhamer, a professor in the Humphrey School and School of Public Health, explored answers to that Big Question at last week’s Frontiers in the Environment event. Here are eight things we learned:
Minnesota is the most water-rich state in the U.S. Despite this, we still have to careful about our water future. We are currently dealing with high levels of unclean water, a problem that may only be exacerbated by increasing stresses such as population growth. We need to think not just about having enough water for everyone, but also about making sure our water is clean and safe.
The Institute on the Environment’s mission is to discover solutions to Earth’s most pressing environmental challenges. Kate Brauman, lead scientist of the Global Water Initiative at IonE, is helping bring this mission to life. Her recent research looking at global irrigation patterns is now being used by Bonsucro, an organization working to use less water in the production of sugarcane around the world. IonE communications director Todd Reubold recently sat down with Brauman to hear the story.
How did you get started in this field?
Agriculture is heavily managed and most of the focus is on the food products that are grown. But at the end of the day crops are still just plants that need water. So when I was working with IonE’s Global Landscapes Initiative team and the data it produces around crop yield, I started asking, “How big a food bang are people getting for their water buck?” In other words, what is the “crop per drop?” Continue reading
This summer, the University of Minnesota’s Institute on the Environment is hosting visiting scholar Tuck Fatt Siew, a postdoctoral researcher at Goethe University Frankfurt in Germany, who is exploring ways to integrate ecosystem services valuation into watershed management in China.
Visiting scholars bring fresh perspectives, “positive disruption” to the day-to-day way of seeing and doing, says Lewis Gilbert, IonE’s managing director. Visiting scholars are not paid by the University or IonE but are given desk space and the use of office equipment. Continue reading
New research from the University of Minnesota’s Institute on the Environment and Stanford University shows that freshwater stream ecosystems are highly vulnerable to oil palm plantation expansion.
The three-year study compared streams draining watersheds dominated by four land uses — intact forest, manually logged forest, community agroforest and oil palm plantation — in West Kalimantan, Indonesian Borneo, which is ground zero for palm oil production. Continue reading
When you think about the primary sources of water pollution, you probably imagine a factory pipe or perhaps massive livestock farms. But would you believe that your quiet neighborhood could be degrading water quality locally and downstream?
That was the topic of the season finale of Institute on the Environment’s Frontiers in the Environment lecture series on Wednesday, May 7, on the University of Minnesota’s St. Paul campus.
In “A Watershed Approach to Understanding Urban Eutrophication,” Sarah Hobbie, an IonE resident fellow and professor of ecology, evolution and behavior in the College of Biological Sciences, discussed how nutrients from lawns, pets and boulevard trees contribute to excessive algal growth in urban water bodies.
Last fall, 10 other people and I paddled more than 2,000 miles in canoes. Our trip was called Paddle Forward, and we were on a mission to paddle the length of the Mississippi River. I’ve been paddling for years but mostly in wilderness areas such as the Boundary Waters. While I love these places and enjoy the quiet time alone in nature, recreating on local waterways brings a new appreciation to the place you live.
I spent the majority of college learning about environmental issues surrounding climate change, such as energy usage, water depletion, resource extraction and decreases in biodiversity. Alone, secluded in serene wilderness, you are less likely to think about difficult climate issues. However, while paddling a river that more than 50 cities depend on for daily water supply, you can’t escape noticing the effects humans have on the fourth largest watershed in the world.

This article is part of a series of profiles of IonE resident fellows highlighting the value of their collaborations across the U of M, Minnesota and the world.
Conventional wisdom has it that farmers and conservationists don’t see eye to eye. Conservationists want to see farmers plant diverse vegetation, in addition to crops like corn and soybeans, that produces ecosystem services; farmers’ main priority is earning a living. Right?
“Farmers care just as much about the environment as anyone, but there are financial realities,” says Nick Jordan, a resident fellow with the Institute on the Environment and an agroecology professor in the College of Food, Agricultural and Natural Resource Sciences. 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.
