Scientists have been significantly overestimating the amount of carbon stored in the world’s tropical forests, a new study shows. Carbon storage estimates matter because world leaders use these numbers to devise carbon trading and mitigation agreements, such as those at the center of the recent 21st United Nations Climate Change talks in Paris.
Deforestation is a huge source of excess carbon dioxide in the atmosphere, and leaders recognize forest conservation and restoration as a critical tool for reducing and mitigating climate change. Continue reading
Renowned environmental researcher, scholar and communicator Jessica Hellmann has been named the new director of the University of Minnesota’s Institute on the Environment. Hellmann, who is currently on the faculty of the Department of Biological Sciences at the University of Notre Dame, will begin her tenure as director of the Institute on the Environment August 31, 2015. She also will join the University faculty as the Russell M. and Elizabeth M. Bennett Chair in Excellence in the Department of Ecology, Evolution and Behavior in the College of Biological Sciences.

MINNEAPOLIS / ST. PAUL (11/19/14) The application of a recently developed crop statistics database at the University of Minnesota’s Institute on the Environment in conjunction with a carbon accounting model developed at Boston University has shown that intensified agricultural production in the northern hemisphere is generating up to a quarter of increased atmospheric carbon dioxide seasonality, reports a paper published in the November 5 issue of the journal Nature.
Deepak Ray, research associate at IonE’s Global Landscapes Initiative, who led the development of the dataset and contributed to this study, said, “This is the perfect example of assembling a multidisciplinary, multi-institutional team of experts tackling an intractable problem of why the atmospheric carbon dioxide seasonality is intensifying.” Continue reading
University of Minnesota ecologist and IonE resident fellow David Tilman has received a 2014 Balzan Prize in recognition of his outstanding scholarly contributions in ecology. The international award comes with an $800,000 prize, half of which is to support young researchers working with Tilman.
According to a release by the International Balzan Prize Foundation, Tilman received the distinction for his “huge contributions to theoretical and experimental plant ecology, work that underpins much of our current understanding of how plant communities are structured and interact with their environment.”
The Balzan Prize recognizes achievements in the humanities and natural sciences, as well as in advancing peace among humanity. The foundation varies the fields it recognizes each year with an eye to uplifting innovative research across disciplinary boundaries. Tilman was one of four scholars from around the world to receive the prize this year. Past recipients of the award include Mother Teresa of Calcutta and the International Committee of the Red Cross.
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
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.”
In April, we announced that IonE director Jonathan Foley will be departing the University of Minnesota Aug. 15 to take a new position with the California Academy of Sciences. Under Foley’s leadership, IonE has grown to be a prominent, internationally recognized organization working to solve grand environmental challenges, and the University intends to uphold those high standards as senior leaders work to define IonE’s future direction and leadership.
To guide IonE through this transition, Vice President for Research Brian Herman has appointed Lewis Gilbert, IonE’s current managing director and chief operating officer, as interim director. Gilbert joined IonE in 2011, bringing with him extensive experience in academic entrepreneurship and in the design, implementation and management of complex interdisciplinary activities in large research universities. Among other accomplishments, Gilbert was one of the key architects in the creation of the Earth Institute at Columbia University. Gilbert will assume leadership of IonE Aug. 15.
Additionally, the Office of the Vice President for Research has appointed a committee to lead a broad, consultative process that will result in a set of recommendations and a strategy for IonE going forward. As part of that process, the committee will consult widely with both internal and external stakeholders to determine the right path forward. Once the committee has made its recommendations, a search committee will be established to develop the profile and search process for the director position. The vice president for research hopes to have the new management structure in place by next summer.
Your input and support will continue to be invaluable going forward as the University establishes a firm foundation and launching pad for the future of IonE.
