Unraveling the complex web of global food tradePhoto by Louis Vest (Flickr Creative Commons)

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

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.

Climate has a big say in crop yield variabilitynews_climatecropyield_main

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

Study: Ag production contributes to CO2 spikesPhoto by James Clear (Flickr/Creative Commons)

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

Shining new light on trees and CO2news_reich_main

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.

Study: Pollinators play vital role in human nutritionnews_study_-pollinators_nutrients

Pollinators have a direct impact on human nutrition, especially in the developing world where malnutrition and micronutrient deficiencies are prevalent, according to new research published today in Proceedings of the Royal Society B. The Natural Capital Project study — a collaboration of the University of Minnesota’s Institute on the Environment and Stanford Woods Institute on the Environment — overlapped data of 115 common food crops with data on pollination dependence and micronutrient content and found that, in places like Southeast Asia and Latin America, almost 50 percent of plant-derived vitamin A requires pollination. Read more

Focusing ag expansion can save billions of tons of carbonAir view, birds eye view of the fields and hills

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

Supporting the White House Climate Data Initiativenews_white_house_climate_data

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.”

Study: How existing cropland could feed billions moreRice being grown in rural China

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.

Study: Groundwater contamination in SE MinnesotaFarm field in Minnesota

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.”

Ellen Anderson named executive director of energy labWind Turbines for Energy Transition Lab

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.
