What environmental challenge concerns you most?
Population control. We are overpopulating and exploiting the Earth and these are at the root of all environmental problems. I do not know how many people a sustainable world can support, but I suspect that it is less than a population of 9 billion. Continue reading
This week Brent Hecht, an assistant professor in the College of Science and Engineering, and Spencer Wood, senior scientist with the Natural Capital Project at Stanford University, joined Frontiers in the Environment to discuss how social media can be used to inform the causes and consequences of environmental change. Here are seven things we learned:
1. We’ve entered a new era of data. The explosion of social media has created an abundance of data not previously available. Geotagged information (the inclusion of geographical information on forms media, such as marking your location in a Tweet) from social media is one way to harness these data in a useful way. Using the combination of location information in conjunction with the information included in the post, researchers can gleam new insights. Continue reading

The higher levels of heat-trapping gases from burning fossil fuels are one feature of what many call the Anthropocene, a new geological era dominated by humans.
Yet regulatory approaches to managing carbon in the Earth system are doomed to fail. This is because the rise of carbon dioxide levels — what I call the CO2 Catastrophe — is taking place at the scale of the Earth system itself. Humans are inside of that system, CO2 emissions are coupled to energy use, and increasing energy use is central to economic advancement. I have become convinced that it is simply not possible to manage energy usage from the scale of households to that of the planet itself using regulatory methods. Continue reading
Carver County, one of seven counties in the Twin Cities metro, has been chosen as the 2015–16 Resilient Communities Project partner. Enhancing bike and pedestrian facilities near park-and-ride locations, evaluating stormwater reuse opportunities, crafting an ecotourism marketing plan and exploring opportunities for preservation of a historic farmstead are among the 34 projects the county will tackle with help from University of Minnesota sustainability expertise.
Buildings are huge parts of our lives, yet we rarely think about what it takes to keep them running. This week, Frontiers took a look at advanced heat recovery, one a way to improve building energy efficiency. Leading the discussion was Patrick Hamilton, IonE resident fellow and director of the Science Museum of Minnesota’s Global Change Initiatives. Panelists were Scott Getty, energy project manager for Metropolitan Council Environmental Services; Katie Gulley, regional program manager with the BlueGreen Alliance; and Peter Klein, vice president of finance for the Saint Paul Port Authority. Here are five things we learned: Continue reading

While studying oil palm plantation expansion in Indonesian Borneo as part of her Ph.D. work at Yale University’s School of Forestry and Environmental Studies, Institute on the Environment postdoctoral scholar Kimberly Carlson witnessed how growing global demand, coupled with poor forest governance, resulted in rapid loss of tropical forests. Led by her adviser Lisa Curran and collaborating with the Indonesian non-governmental organization Living Landscapes Indonesia, Carlson has helped uncover the impacts of oil palm development on forest loss, carbon emissions and stream water quality. She finished her Ph.D. wishing not only to document the dynamics and effects of agricultural land use change, but also to design studies that directly inform tropical land use policy.

What is your current favorite project?
I’m working with colleagues at Cornell University to understand how and why the environmental “stories” recorded by trees differ from place to place. Every year, trees in Minnesota and other parts of the world with strongly seasonal climates form a new layer of wood around their stem. That layer of wood — a tree ring — is very clear evidence of the passing of time and records, indirectly, the immediate environment of that tree. Over the last several decades scientists have collected tree-ring records from hundreds of thousands of trees around the planet. A tree ring may be a very simple thing, but reading millions of them at the same time might tell us a great deal about the environmental past (and perhaps future) of our planet. Continue reading
Passage of the Clean Air Act and Clean Water Act in the early 1970s were clear public policy wins for the environmental movement. But are we still able to make progress through government action in the same way we did 40 years ago? Eric Lind, a postdoctoral associate in the College of Biological Sciences, was curious about what “successful” government action on the environment looks like today, so he asked three professionals to share their experience in this week’s Frontiers on the Environment. Kate Knuth, Boreas Leadership Program director, spoke of her experience as a Minnesota state representative, followed by Julia Frost Nerbonne, executive director of Minnesota Interfaith Power and Light, and Jessica Tritsch, senior organizing representative for Sierra Club’s Beyond Coal to Clean Energy Campaign. Here are seven things we learned: Continue reading
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

The top-level teams and other awardees will have the opportunity and resources to further develop their innovative business solutions for environmental and social challenges. Continue reading
Along with being one of the happiest nations in the world, Denmark is known for being one of the most environmentally friendly. Which raises the question: Is a happy society a more sustainable one? After spending time in the country for a course last summer, Sustainability Education coordinator Beth Mercer-Taylor; Mallory Thomas, an evolution and behavior student in the College of Biological Sciences; and Stephanie Claybrook, an art student in the College of Liberal Arts, put together 10 pillars of Danish happiness. Can we use these tools to work towards sustainability at home?
1. Social security. Compared to the United States, the wealth gap of Denmark is very small. This may be due to the fact that Denmark boasts one of the highest income taxes in world, about 60 percent. In return, its residents receive security, flexibility and unemployment benefits. Continue reading

How does your work align with the mission of IonE?
All of my projects focus on various aspects of biodiversity — origins, monitoring biodiversity remotely, links in biodiversity between trophic levels, patterns of biodiversity in urban areas, the value of biodiversity to humans. Most relevant to IonE’s mission, perhaps, is the SESYNC (Socio Environmental SYNthesis Center) working group I am leading with Steve Polasky on the ecosystem services that plant species around the globe provide. A component of this project involves putting a partial monetary value on a species, which is obviously very controversial. 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:

What pivotal moment led you to the work you’re doing today?
A study abroad experience my junior year of college. I spent a semester in Kenya studying wildlife management at The School for Field Studies. I was a biology major trying to decide between becoming a doctor or a vet. That experience made me realize that wildlife research was another option. And my current job is awesome ‘cause I get to work with vets! Continue reading
Artist Marjorie Schalles had a case of cabin fever and needed an escape from the house in the winter of 2010. She and her husband decided to take a walk around the Mall of America, where they stumbled upon an exhibit of images of Earth captured by NASA satellites, sponsored by the U.S. Geological Service. The shapes, colors and textures of deltas, mountain ridges and other geographical features so excited her that she decided to use them as subjects for her paintings.
The result is an ever-expanding collection called earth, currently on display in the Institute on the Environment’s Commons Meeting & Art Space.
What better way to kick off the new round of Frontiers than by crossing national boundaries? In the first talk of 2015, Frontiers was joined by Martin Bigg, professor at the University of West England; Gayle Prest, sustainability manager for the City of Minneapolis; and Simon Sharpe, head of climate risk for the UK Foreign Office. This international panel provided information and inspiration on the ways in which cities matter for climate change. With case studies from Bristol to Minneapolis, here are six things we learned:
- The many lessons of Bristol. Located in the western UK, Bristol is not just any city — it’s the 2015 European Green Capital. After beating out serious competition, such as Brussels and Glasgow, the city does not take this title lightly. Now ranking with the likes of Copenhagen and Stockholm, Bristol has a commitment to reduce emissions and promote public transportation. To do this, it has reduced speed limits inside the city, added hybrid buses and invested in “poo-buses” (yes, really) powered by biomethane made from human and food waste.
Growing global trade is critically important for providing food when and where it’s needed — but it makes it harder to link the benefits of food and the environmental burden of its production. A study published this week in the journal BioScience by an interdisciplinary team of researchers at IonE proposes to extend the way we characterize global food trade to include nutritional value and resource consumption alongside more conventional measures of trade’s value.
“Trade is usually described in terms of the value or weight of the goods being exchanged,” said study lead Graham MacDonald, a postdoctoral research scholar with IonE’s Global Landscapes Initiative. “But these don’t necessarily capture other important aspects of food production and distribution. Accounting for food’s nutritional value and the land and water resources needed to produce exports offers a more holistic view of how trade affects global food security and the environment. Our study uniquely juxtaposes these perspectives.” Continue reading
Each spring semester since 2011, scholars from places as diverse as Mexico, Brazil, Arizona and Minnesota have met in a virtual classroom. They hail from many disciplines and represent diverse cultural perspectives. Despite their differences, they convene under a common goal: the study of sustainability science.
This unique course, known as the Sustainability Science Distributed Graduate Seminar, focuses on core theories of sustainability science, an emerging field of problem-driven research dealing with interactions between humans and the environment, says Jeannine Cavender-Bares, an associate professor in the University of Minnesota College of Biological Sciences.

What is the current focus of your work?
My team in the Department of Civil, Environmental and Geo- Engineering is studying how human impacts on the composition of organic matter in natural waters — due to wastewater, stormwater or agricultural runoff — affect the solar-driven reactivity with various contaminants, including pesticides and pharmaceuticals. We are trying to understand how the molecular structure and properties of organic matter influence the production of highly reactive intermediates (such as the hydroxyl radical) that are important in the destruction of contaminants. The ultimate goal is to be able to predict how fast various contaminants will degrade in different impacted waters and to design treatment systems that take advantage of sunlight-driven reaction processes.

Even at historically low natural gas prices, bioenergy may not be out of the running — it just may need a little help from the sun. A new study from researchers at the University of Minnesota examining the financial viability of solar-heated biomass gasification technologies that produce a natural gas substitute product concludes that combining these renewable resources can make economic sense.
In traditional biomass gasification, 20 to 30 percent of the biomass feedstock is burned to produce heat for the process. But if the required thermal energy is supplied from a concentrated solar source, all of the biomass can be converted into useful synthesis gas. The study, published in Biomass and Bioenergy this week, developed a financial feasibility metric to determine the breakeven price of natural gas at which the produced syngas could be sold at a profit. The study suggests that solar-heated biomass gasification systems could break even at natural gas prices of $4.04–$10.90 per gigajoule, depending on configuration. Continue reading
