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
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
What impact will future climate change have on food supply? That depends in part on the extent to which variations in crop yield are attributable to variations in climate. A new report from researchers at IonE’s Gobal Landscapes Initiative has found that climate variability historically accounts for one-third of yield variability for maize, rice, wheat and soybeans worldwide — the equivalent of 36 million metric tons of food each year. This provides valuable information planners and policy makers can use to target efforts to stabilize farmer income and food supply and so boost food security in a warming world. Continue reading
A project aimed at developing magnets that don’t require the use of rare earth elements captured the $10,000 top prize in a Dow Sustainability Innovation Student Challenge Award (SISCA) competition held Dec. 4 at the University of Minnesota’s Institute on the Environment in St. Paul.

How much do trees vary in the way they suck carbon dioxide from the air and use it to make roots, trunks, branches and leaves? The answer to that question is an important one because it has a huge impact on our ability to predict how destroying or creating forests influences climate change. And the correct answer is a surprising one, according to two related studies published in the Proceedings of the National Academy of Sciences this week by University of Minnesota forest ecologist Peter Reich and colleagues in Minnesota, Arizona, Australia, China, Poland and Germany.
Conventional models used to assess the impact of forests on greenhouse gas concentrations in the atmosphere assume that the way trees use carbon to build roots, leaves and trunks is fairly constant across a range of conditions — that is, that trees everywhere devote the same fraction of new growth to each component and that components have the same durability everywhere. However, analyzing massive amounts of data gathered from around the globe, Reich and colleagues documented predictable differences in key properties of forests across north-south climate gradients.

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.
Congratulations to the four latest recipients of Institute on the Environment Project Grants! IonE Project Grants (formerly known as Discovery Grants) help highly innovative, world-class research activities get off the ground with a one-time investment of venture capital funding. The new recipients for fiscal year 2014 are: Continue reading
Our energy system is in the midst of a major transition. Our power sources are shifting from coal to more natural gas and renewables. We need to upgrade our aging grid to accommodate those new sources. As our grid becomes “smarter,” we need it to be responsive and reliable. And new greenhouse gas emissions regulations and the need to make our grid resilient as the climate changes add further complexities.
This energy transition has the potential to spark innovation in business and the public sector, leading to new jobs and better outcomes for the community and our environment. Reaching that potential requires strong leadership. To provide that leadership, the University of Minnesota is launching the Energy Transition Lab with former state senator Ellen Anderson (J.D. ’86), senior advisor on energy and environment to Governor Dayton, as its inaugural executive director.

What does education look like in remote mountain villages where electricity is nonexistent or unreliable? How does a developing country seeking to grow its economy, boost tourism and expand its infrastructure do so sustainably?
Earthducation Expedition 6 aims to find out — and share what it learns with teachers and students around the world. This sixth in a series of seven-continent explorations investigates the intersections between education and sustainability in Nepal, the roof of the world. Led by Aaron Doering and Charles Miller of the University of Minnesota’s College of Education and Human Development with funding from the University’s Institute on the Environment, the expedition will set out April 27 for a journey to this diverse ecological powerhouse that boasts some of the most majestic geographical wonders on Earth.

(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

(12/22) Plant researchers, including Institute on the Environment resident fellow Peter Reich, have assembled the largest evolutionary tree to show the order in which flowering plants evolved specific strategies, such as the seasonal shedding of leaves, to move from warm climates into areas with cold winters. How they managed this expansion has long vexed researchers searching for plants’ equivalent to the winter parka. Read more
