Are crop yield trends on track to meet future demand?NeilPalmer CIAT

Several reports estimate that global crop production needs to double by 2050 to meet the demands of more people, more people eating meat, and more crops being used for biofuel production. I previously wrote a post about five strategies for increasing food security while improving the environment. One strategy is quite obvious: Increase crop production. We need more food, so let’s grow more on our current cropland or expand into new areas. Sounds simple, right? Let’s unpack a few of the details to see if we’re on track to meet projected needs in the coming decades. Continue reading

Dripping with potentialMy Rain 2

“I should be ashamed of this, but I’m not.”

After spending the last year in rural India building the MyRain business he co-founded with his partner Paula Uniacke, Steele Lorenz (BS ’10) was ready for some comfort snack food. So when I asked him if he wanted anything from the U.S. before I left, he gave me a list that included items like Little Debbie cookies and Kraft Macaroni and Cheese. On the trip over to India, I learned that Little Debbie cookies caused TSA more problems than anything else I have ever carried onto an airplane. They seem to be impenetrable to X-rays. “I should be ashamed of this list, but I’m not,” Steele confided to me. The work Steele has done with MyRain over the past year, however, deserves a whole shipping container of cookies.

Participants may choose from two complementary courses – Culture, Food and Agriculture and Experiencing Sustainability – or enroll in both. Continue reading

Grown to runGrown 2 Run 2

On Friday, May 10, a group of graduate students and a professor from the University of Minnesota set off for the Minnesota-South Dakota border excited and anxious. The plan: go from farm to farm and school to school by bike and on foot, collecting media artifacts on innovative agricultural practices for 7th-12th grade teachers and students following along.

Toward the end of the first day the “Grown to Run” adventure learning team saw plumes of white and gray smoke drifted across the road. Traffic slowed as flames flickered from a prairie reserve being burned by the Minnesota Department of Natural Resources. Armed with cameras, the G2R team videotaped a segment of the daily adventure update that would illustrate the role fire plays in prairie ecosystems. Continue reading

Soil surpriseCedar Creek

Living things that lurk beneath the surface of the soil have huge impacts on living things above, influencing everything from individual plants’ ability to obtain nutrients to the integrity of the elaborate food webs that keep animals of all shapes and sizes alive. Now, thanks to research by IonE resident fellows Peter Reich (College of Food, Agricultural and Natural Resource Sciences), Sarah Hobbie (College of Biological Sciences) and colleagues, it’s clear that what’s happening above the surface has a huge impact on the living things below as well.

Frontiers: University-community collaboration: Cool!RCP

How can we build long-term capacity to produce sustainable solutions and resilient institutions? How can we foster innovation in engagement and cross-disciplinary collaboration in universities? Carissa Schively Slotterback, IonE resident fellow and associate professor at the Humphrey School of Public Affairs, addressed these questions during the April 24 Frontiers in the Environment seminar, “University-Community Collaboration to Advance Sustainability.”

The case of too much or too little nitrogen fertilizerNational Geographic

Many of the increases in food production during the Green Revolution can be attributed to a single element in the periodic table — nitrogen. Begun in the early 1900s as an effort to convert nitrogen gas from the air we breathe into a solid form that could propel ammunition farther, the Haber-Bosch process later became the key mechanism for boosting crop yields through mass production of nitrogen fertilizer. Unfortunately, excess nitrogen degrades our drinking water quality, causes many coastal areas to be oxygen-depleted “dead zones,” and adds a very powerful greenhouse gas to our atmosphere. How can we manage our farmlands more effectively?

Frontiers: Three questions about air pollutionJulian Marshall

More than 2 million people die each year from the health complications of air pollution, such as heart disease, lung cancer, asthma and acute lower respiratory infections, according to the World Health Organization.

Julian Marshall, IonE resident fellow and assistant professor of environmental engineering in the College of Science and Engineering, addresses the problem of air pollution by asking three questions.

Acara meets Kampalakampala

Over spring break, it’s not unusual to go south to get some sun, but I took it to an extreme. I spent the week a few miles north of the equator, in Kampala, Uganda, teaching Makerere University students about social entrepreneurship.

This course at Makerere University is part of the USAID-sponsored RESPOND program, in which the University of Minnesota is playing a major role. RESPOND is creating capacity to strengthen outbreak response for emerging infectious diseases from humans, domestic animals and wildlife.

Frontiers: A mangrove lagoon in the time of climate changeMangrove

Imagine living in a region where your livelihood depended on the frequent flooding of your property.  David Lipset has lived with and chronicled the lives of people who make such a location their home. He shared how a population of roughly 3,000 in the Murik Lakes region of Papua New Guinea is being effected by rising sea levels at the March 6 Frontiers in the Environment seminar, “A Mangrove Lagoon in the Time of Climate Change: The Politics, Science and Culture of an Intertidal Environment in Papua New Guinea.”

Frontiers: Sound ecologyEcology of Sound

What is noise, and how does it affect the natural world? These are among the questions Mark Pedelty, IonE resident fellow and College of Liberal Arts associate professor, posed at his February 27 Frontiers in the Environment seminar, “Sound Ecology: The Environmental Effects of Mechanical Noise and Human Music.”

Pedelty is hoping to influence land development policy to take the effects of mechanical and human noise into account. For example, he noted that some songbirds sing louder and at a higher pitch in urban landscapes, and industrial noise has been shown to inhibit foraging and reproduction in certain frog species.

Frontiers: Clean water, wild places, healthy communitiesWatersheds

Tim Bristol is playing offense. That’s how the Trout Unlimited Alaska director described his group’s efforts to protect Alaska’s vital watersheds at the Feb. 20 Frontiers in the Environment seminar, “Watersheds: Clean Water, Wild Places, Healthy Communities.”

Trout Unlimited Alaska is fighting to protect two critical habitats and communities that rely on them: Bristol Bay in southwestern Alaska and the Tongass National Forest in the southeastern panhandle. Both areas boast productive salmon fisheries that have vital economic benefit to the communities that rely on them, said Bristol. Both are at risk from development projects that threaten the health of their watersheds.

Acara: The SequelAcara: the Sequel

After a student takes a course from IonE’s Acara program for budding social entrepreneurs, then what? Do the lessons learned get filed away with old exams and term papers – or do they take on a life of their own?

Of course, each student’s story is different. But for many, Acara turns out to be a springboard to new ideas, opportunities and adventures. Below is a short, informal update on some of the teams and ventures that were part of the Acara program during 2012. Whatever the path, it’s clear that their experience in the Acara program gives them a solid foundation for future endeavors.

Putting the “U” in communityARCH students at Minnehaha Creek

Writing term papers, doing problem sets … it’s easy for college students to wonder whether what they do really matters. But members of 10 University of Minnesota classes last fall had no question at all about the relevance of their work. Inaugural participants in the University’s new Resilient Communities Project, they spent their semester helping solve very real sustainability challenges for the city of Minnetonka. Continue reading
