Over the past 200 years, Iowa’s once ubiquitous prairies have been almost totally edged out by farmland and urbanization. Only a fraction of one percent of what used to be remains. It is unlikely that Iowa’s prairies will ever be restored to their full former glory, but some counties are regenerating slivers of native prairie along county roadsides.
The practice, called Integrated Roadside Vegetation Management, cannot reestablish the value of Iowa’s lost prairies, but it does help humans and nature coexist little more sustainably. The strips of prairie:
Create habitat for species like pollinators, birds and small mammals
Trap pollutants and sediments that would otherwise contaminate water and soil, like motor oil and road salt, while remaining tough enough to withstand harm
Promote soil health and reduce flooding by incorporating air and organic matter into the soil structure
Give drivers a glimpse at the state’s historic beauty
Counties aim to manage these areas sustainably with minimal use of pesticides, strategically timed mowing and burning. These efforts are funded through the Living Roadway Trust Fund and supported by the University of Northern Iowa Tallgrass Prairie Center. Over 100,000 acres have been planted since the start of the program in 2009.

Andrey Petrov, director of the University of Northern Iowa Arctic Center, led a study of the largest reindeer herd in the world, located on the Taimyr Peninsula in the northernmost tip of Russia. Petrov’s work shows that the herd’s population has dropped from 1 million reindeer in 2000 to about 600,000 today. Scientists say rising temperatures in the region may be the cause.
Petrov said, “Climate change is at least one of the variables.” He added, “We know in the last two decades that we have had an increase in temperatures of about 1.5C overall. And that definitely impacts migration patterns.” During his presentation at the Fall Meeting of the American Geophysical Union (AGU) in San Francisco on Monday, Petrov explained that the longer distance the animals have to travel in order to find cold weather is increasing calf mortality. When the reindeer have to travel further and to higher elevations in the winter, it is also more difficult to find land bearing food in the summer months. Petrov also explained that the region’s rivers are growing wider as ice in the area melts, causing more deaths as the herd attempts to swim across bodies of water.
“Reindeer are tremendously important for biodiversity – they are part of the Arctic food chain and without them other species would be in trouble,” he said. Petrov added, “Thousands and thousands of people rely on wild reindeer; it is the basis of their subsistence economy. So it’s about human sustainability too.”
Wild reindeer are also shrinking in size. Scottish and Norwegian researchers recently released a study which found that the average weight of reindeer on Svalbard, a chain of islands north of Norway, has fallen from 121 lb. in the 1990’s to 106 lb. today. Professor Steve Albon, an ecologist at the James Hutton Institute in Scotland, said, “Warmer summers are great for reindeer but winters are getting increasingly tough.” The researchers explained that less snowfall during warmer winters means that the reindeer have to traverse sheets of ice, making it harder for the animals to reach food sources.
In contrast to the Tamiyr population, the Svalbard herd is growing in size.”So far we have more but smaller reindeer,” Albon said. He added that the growing population means competition for food has become more intense.
This week’s On The Radio segment discusses Sandra Steingraber and her recent visit to the University of Northern Iowa
Transcript: Long time environmental activist, Sandra Steingraber recently hosted a lecture, film showing and discussion at the the University of Northern Iowa.
This is the Iowa Environmental Focus.
Steingraber visited UNI to discuss three of her recent articles and give a lecture entitled “Be Arrested If Necessary.” She spoke about the role of environmental science as a catalyst for political and cultural change.
Sandra Steingraber, lives in Trumansburg, New York and has worked for years with government officials and other activists to bring about changes in her home state and around the country. She is a co-founder of Concerned Health Professionals of New York and New Yorkers Against Fracking and is currently the science advisor to Americans Against Fracking. In twenty-fourteen she led a successful campaign against fracking, resulting in the process being banned in the Empire State.
Steingraber is working hard to bring awareness to the effects of environmental degradation due to chemical contamination, fracking, shale gas extraction and climate change.

New research suggests that as much as half of the food produce in the United States is wasted.
A “demand for unattainable perfection” in the appearance of fruits and vegetables is largely to blame for the vast amount of wasted food. Fruits and vegetables are often led in the field to rot, fed to livestock, or shipped directly to landfills when deemed unsellable because of cosmetic imperfections. According to government data, about 60 million tons of produce, worth about $160 billion, is wasted by American retailers and consumers annually. Globally, about 1.6 billion tons, valued at about $1 trillion, is wasted each year.
Last year U.S. Secretary of Agriculture and former Iowa governor Tom Vilsack called for a 50 percent reduction in food waste by 2030. However, one expert argues that Vilsack’s goal could have a negative effect on food economics. Roger Gordon – founder of the Food Cowboy – told The Guardian that a 50 percent reduction in food waste could reduce the profit margin of produce at grocery stores by half. He added that fresh produce accounts for about 15 percent of supermarket profits.
Officials with the University of Iowa’s IIHR-Hydroscience & Engineering hosted an event Wednesday in Coralville focused on reducing flood damage and improving water quality within the Clear Creek Watershed.
IIHR-Hydroscience & Engineering Director Larry Weber was the event’s main presenter as he discussed efforts in the Clear Creek Watershed which will in part be funded by a $96.9 million grant awarded to the state of Iowa in January by the U.S. Department of Housing and Urban Development (HUD). More than 60 were in attendance for Wednesday’s event at the Coralville Public Library including representatives from city, county, and state governments, Iowa’s three regent universities, the Iowa Department of Natural Resources (DNR), the Federal Emergency Management Agency (FEMA), landowners, farmers, and various engineering firms. Weber said he thinks cooperation between public and private entities will be key in many of the upcoming projects.
“It is a great partnership between the public and private sectors. With the federal and state agencies they have a jurisdiction and they have an authority. So they all work within in their authority to contribute to the program,” said Weber. “Then we have the private sector involved through design consultants, engineering services, technical assistance, and what I was really impressed with in today’s meeting were the number of landowners that were here. So there’s interest. We know there is interest in landowners wanting to make their waters better and to have that number of landowners here interested in the program, already thinking about practices they might want to enroll on their property, that’s exciting.”
The $96.9 million grant was awarded to Iowa through the National Disaster Resilience Competition. The landlocked Hawkeye State received the fourth largest amount of funding behind disaster-prone coastal areas. Weber said this large sum of funding shows the need for pursuing these projects in Iowa.
“It is really interesting especially since this competition was born out of Superstorm Sandy. The largest recipient was the state of New York followed by Virginia and then New Orleans which has been impacted by every landfall and gulf coast hurricane over the last decade,” said Weber. “Iowa was fourth behind those disaster-prone areas so it really spoke to how well the partnership was, how sound the approach is, and how great the ideas are.”
Weber also said that IIHR’s prior involvement in HUD-funded projects made the process easier when pursuing the most recent grant.
“The Iowa Flood Center and IIHR was fortunate to be part of the team that helped to create this proposal and having the experience from running the previous HUD project we knew what the needs were. We needed money for conservation, we needed technical design assistance, we needed project coordinators, we needed the monitoring and modelling and other outreach services that we provide. So when we saw how all of those elements could fit together we wrote a compelling story for HUD and then ended up with a successful proposal.”
Another reason Iowa was successful in receiving the HUD funding was because of programs and other efforts already in place that will contribute to the HUD project. The Iowa Flood Center, the Iowa Nutrient Research Center, the Iowa Geologic Survey, the Iowa DNR, the Iowa Department of Agriculture and Land Stewardship, and other agencies already have programs in place which HUD felt could be further developed with the funding it granted to Iowa.
In addition, Weber said Iowa was unique among its adversaries in the National Disaster Resilience Competition because of the amount of local financial support for the practices outlined in the state’s plan.
“We have 25 percent local support of these practices. So think about going to a coastal area where they’re going to build a seawall. They don’t ask the residents behind that seawall to commit 25 percent of the funding yet here we’re building practices on private land for public benefit and we’re getting that landowner to cover 25 percent of that cost.”
Weber credited the Iowa legislature and other state leaders for their support with establishing the Iowa Flood Center and funding other water-related activities in the state which helped Iowa’s case when applying for the recent HUD funding.
“Without that commitment we wouldn’t have had the leverage that we did and we wouldn’t have been successful like we were,” he said.
Andrew Stephenson (Project Coordinator, Center for Social and Behavioral Research): “One of the many aims of this project was to gather baseline information on Iowans’ reported engagement in positive behaviors related to water quality, such as picking up pet waste, washing vehicles at commercial car washes, and properly disposing of hazardous waste. Using this information, the Department of Natural Resources will work to develop an outreach campaign that educates the public and encourages positive behavior change among Iowans to improve and protect the quality of Iowa’s lakes, rivers, and creeks. Additionally, these data can serve as a benchmark to which the DNR can compare future measures to evaluate the effectiveness of their outreach efforts.”
Water-saving behavior changes could include refraining from pouring fat or oils down the drain, avoiding the garbage disposal and composting instead, going meatless for one day per week, and even placing a brick or half-gallon jug in a toilet tank to save water when flushing.
“Students will learn about global environmental problems, particularly issues that are directly linked to human health,” Dr. Iqbal said in a press release. “This will be a great opportunity for our students to develop respect and understanding for people of a different culture, specifically for those people who are living in adverse environmental conditions.”
The researchers started on the project during May of this year when Dr. Iqbal and two of his students traveled to Nepal. The researchers conducted water and sentiment sampling, analyzed procedures, and implemented policy changes using scientific data. The team is expected to continue working on the project through the end of 2016. Funding for this project was made possible because of a $56,000 grant from the National Science Foundation (NSF).
The Bagmati River study is just one of the international research efforts in which UNI is participating. Last month NSF awarded UNI with nearly $750,000 to study environmental sustainability in the arctic. UNI will work with researchers from in Canada, Greenland, Iceland, Norway, Russia, and Sweden on the project.
