Stormwater falling on paved and other impermeable surfaces is the main source of urban runoff. That water is laden with nutrients and minerals that are detrimental to the water quality of rivers and lakes.
IonE resident fellow John Gulliver, a professor in the College of Science and Engineering, has spent more than a decade working on ways to protect water from the ravages of runoff. Continue reading
Do you know about the Water Framework Directive? It calls for all waters in the European Union to be managed as river basins and for those river basins to be brought up to “good status.” That’s tremendous – a really forward-looking way to think about managing water. But as you can surely imagine, it’s also quite a task to implement!
I was lucky enough to work with the RISKBASE group during 2009-2010 to help develop risk-based approaches for managers to guide river basins to good status. I’m not an expert in risk, nor an expert about European river basins, but I was really excited to get involved. This had the potential to bring biophysical science together with new management approaches to actually solve problems. Continue reading
What do eight U.S. states and two Canadian provinces have in Common? The Great Lakes! Recently, Detroit Public Television’s Great Lakes Now Connect invited Institute on the Environment resident fellow Stephen Polasky to join a panel of experts to talk about the importance of investing in natural environments to enhance the quality of the Great Lakes.
It’s easy to understand that clean water is important for drinking, fisheries, irrigation, recreation and other benefits that people reap from the Great Lakes. What may not be as obvious is the effect that coastal and upland habitats have on water quality. Continue reading
Spirited voices mixed with the scent of Indian spices in The Commons: Meeting and Art Space at Institute on the Environment last Monday night. Dozens of Acara students, mentors and investors were gathered for a showcase of the 2012-13 Acara Challenge contestants.
Attendees supped on fare from Gandhi Mahal and mingled with the young entrepreneurs before settling in for brief presentations on seven start-ups developed by Acara alumni. The goal of each business – in addition to viability and profit – is to address a social or environmental issue at home or abroad. Continue reading
The MyRain train just keeps on rolling. A couple of weeks ago the Acara Challenge start-up was featured in Bloomberg Businessweek. Now the team has been named to the Fall 2013 Global Social Benefit Incubator (GSBI) online cohort at Santa Clara University Center for Science, Technology, and Society. Continue reading
We use more water for agriculture than for any other human activity on the planet, so water sustainability and food security are closely linked. And as demand for water increases — for domestic, industrial, and other uses, as well as for in-stream flows for nature, fishing, and recreation –demand for food expands as well due to our growing populations and changing diets. This dilemma will only create more pressure to optimize the efficiency of water use in crop production.
But how do we know where we might get more food “bang” for our water “buck”? I recently led a study evaluating how crop water productivity — the amount of crop produced per drop of water used — varies across the globe. We discovered that it varies significantly, even between places that have about the same climate. This shows that there is a “water gap” in some areas, which means they could be getting a lot more crop per drop. Continue reading
Tom Johnson, a University of Minnesota Duluth Regents professor and Institute on the Environment resident fellow, knew his work on Lake Malawi in 2005 would yield significant scientific discoveries. Now, eight years later, he and his colleagues have announced research that impacts our knowledge of the near extinction of the human race. They have determined that 75,000 years ago, the Toba volcanic eruption in Sumatra did not cause a volcanic winter or the dramatic drop in human population in Africa, as some anthropologists had proposed.
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?
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.”
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.
What do prehistoric cave dwellers and today’s humans have in common? The ongoing quest for fuel sources. Humans have always had an energy crisis, said Larry Wackett, IonE resident fellow and professor at the BioTechnology Institute, at the first Frontiers seminar of the spring semester: Is Frac(k) A Four-Letter Word?
