Meeting the growing demand for food and other agricultural products is one of the most daunting challenges we face today. At the same time, clearing forests and grasslands for farming releases carbon into the atmosphere, fueling climate change, a similarly alarming and expensive problem.
A study published today by University of Minnesota researchers in Proceedings of the National Academy of Sciences found that limiting agricultural expansion to several key global regions could meet the predicted need to double food production by 2050 while preserving nearly 6 billion metric tons more carbon than would be safeguarded with unguided expansion. Preserving this much carbon is worth approximately $1 trillion in terms of climate change mitigation. Continue reading
The Office of the President of the United States announced a significant expansion of the White House Climate Data Initiative yesterday in Washington, D.C. Through a partnership with the Kellogg Company, the Institute on the Environment’s Global Landscapes Initiative will support this effort by providing maps and data showing the potential impacts of climate change on global agriculture.
“Through his Climate Data Initiative, President Obama is calling for all hands on deck to unleash data and technology in ways that will make businesses and communities more resilient to climate change,” said John P. Holdren, President Obama’s Science Advisor, in a press release. “The commitments being announced today answer that call by empowering the U.S. and global agricultural sectors with the tools and information needed to keep food systems strong and secure in a changing climate.”
Feeding a growing human population without increasing stresses on Earth’s strained land and water resources may seem like an impossible challenge. But according to a new report by researchers at the University of Minnesota’s Institute on the Environment, focusing efforts to improve food systems on a few specific regions, crops and actions could make it possible to both meet the basic needs of 3 billion more people and decrease agriculture’s environmental footprint.
The report, published today in Science, focuses on 17 key crops that produce 86 percent of the world’s crop calories and account for most irrigation and fertilizer consumption on a global scale. It proposes a set of key actions in three broad areas that that have the greatest potential for reducing the adverse environmental impacts of agriculture and boosting our ability to meet global food needs. For each, it identifies specific “leverage points” where nongovernmental organizations, foundations, governments, businesses and citizens can target food-security efforts for the greatest impact. The biggest opportunities cluster in six countries — China, India, U.S., Brazil, Indonesia and Pakistan — along with Europe.
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.”
Four teams with roots in the Institute on the Environment’s Acara program have advanced to the semifinals in the 10th annual Minnesota Cup, the state’s largest venture competition.
Acara is a social entrepreneurship program that helps University of Minnesota students develop impact ventures that address societal and environmental challenges through courses, workshops and field experiences.
The four Acara-based social ventures were chosen from a pool of 1,300 and will be competing against 66 other teams for up to $30,000 in seed money for their start-ups. The ventures are:
- MyRain – supplies drip irrigation systems to small-plot farmers in India
- Pragati Palms – markets sustainably sourced Indian artisan crafts
- Mighty Axe – grows Minnesota hops for local brewers
- BDW Technologies – is instituting a process for genetically engineering probiotic bacteria to counteract infection in farm animals.
In addition, IonE managing director and chief operating officer Lewis Gilbert has been advising another finalist, Kate Thompson of Ground Truth Collaborative.

Faculty from across the U of M accept the challenge of addressing environmental problems through interdisciplinary work
MINNEAPOLIS / ST. PAUL (2/18/14)—Seven University of Minnesota faculty from seven different colleges have been named resident fellows of the Institute on the Environment. Representing a range of disciplines, the new fellows join 58 others conducting interdisciplinary projects that seek to understand and address environmental problems.
Fellows maintain their appointment in their own departments, but receive additional funding to pursue projects that cross disciplinary boundaries. The fellowships also help accelerate professional and leadership development. Continue reading
(1/21) Recognizing that the vast bulk of most companies’ carbon footprint rests in its supply chain, the University of Minnesota Institute on the Environment’s NorthStar Initiative for Sustainable Enterprise has teamed up with CDP (formerly the Carbon Disclosure Project) to help global suppliers reduce their carbon emissions. Six large customers – Bank of America, L’Oreal, PepsiCo, Philips, Vodafone and Walmart – and over 100 of their suppliers are participating in the pilot program. Read more
