In episode 7 of EnvIowa, we sit down with Dr. Larry Weber to learn more about the Iowa Watershed Approach. Dr. Weber is a UI professor of Civil and Environmental Engineering and Director of IIHR–Hydroscience and Engineering, which is the parent organization of the Iowa Flood Center.

Dr. Weber explains how the $96.9 million project came to be and how it improves quality of life for Iowans while protecting our natural resources and health. He tells of successes the Iowa Flood Center has had with its flood reduction and water quality improvement programs and discusses the organization’s fight to maintain state-funding earlier this year.

The director and his team work many long days and spend hours each week driving around the state to each of the nine watersheds included in the Iowa Watershed Approach. For Dr. Weber, his work’s motivation is clear. He said,

“As an Iowan, I grew up here, I’ve worked and spent my whole career here, and I plan to retire here. I want a livable state in which we can enjoy our water and natural resources, enjoy being in the outdoors, enjoy interacting with the rivers, lakes and streams of Iowa, and, you know, programs like the Iowa Watershed Approach, I think, are vital to the long-term sustainability of our resources in Iowa.”

Results from the Iowa Farm and Rural Life poll were released last month, providing insight into rural public opinion on a variety of topics.

The Iowa Farm and Rural Life poll, managed by the Iowa State University Extension Sociology, was established in 1982 and is the longest running survey of its kind. This year’s survey was completed by 1,039 farmers, who were 65-years-old on average. The poll is sent to the same 2,000 farmers every year so that researchers can track changes over time. This year, it asked respondents about conservation techniques, farming practices, monarch butterfly population restoration and trustworthy information sources.

According to the poll, 42 percent of farmers surveyed practice no-till farming, which can be effective in reducing topsoil erosion. On average, farmers lose 5.8 tons of topsoil per acre per year which can lead to a loss of 15 bushels of yield per acre each year, according to the Corn and Soybean Digest. Buffer strips along water ways and field edges to filter nutrients and sediment from runoff was the most common conservation practice among respondents. Forty-six percent of farmers reported using buffer strips in 2015, while fewer than 40 percent reported implementing extended crop rotations, terraces, or ponds.

The survey also asked about participation in The Natural Resources Conservation Service (NRCS) programs. NRCS is the arm of the U.S. Department of Agriculture charged with the protection of natural resources on agricultural lands. It provides technical and financial support to farmers looking to conserve soil and water. More than 60 percent of farmers said that they were currently participating in an NRCS program, just about 34 percent said that they were not. For those not enrolled in NRCS programs, their primary reason was that they did not believe they had enough natural resources on their land to warrant participation.

The farm poll also analyzed which sources of agricultural advice respondents were most likely to trust. More than any other source, farmers said they would be most likely to trust another farmer that grows nearby.

The survey is collaborative project of Iowa State University Agriculture and Home Economics Experiment Station, ISU Extension Service and the Iowa Department of Agriculture and Land Stewardship. “Information from the Farm Poll is used to guide policy decisions and actions and as the basis for public policy seminars, Extension reports, radio and television broadcasts, and newspaper and journal articles,” reads the Iowa State University Extension site.

Iowa Flood Center endangered by state budget proposal

The Iowa Legislature released a budget proposal on Tuesday that would effectively close down the Iowa Flood Center at the University of Iowa.

The proposed budget cuts would eliminate $1.5 million in state funding for the Iowa Flood Center (IFC), which was established by the legislature shortly after floods devastated much of eastern Iowa in 2008.

Dave Wilson is Johnson County Emergency Manager. He said, “Before the floods of 2008, it was hard to communicate the risk to the public in a form they can understand. Pulling the funding for that project would be shortsighted. I’m kind of shocked they are even considering it.”

Slashed funding would mean that the center’s Iowa Flood Information System (IFIS) would also be shut down, according to a statement by IFC’s co-directors Larry Weber and Witold Krajewski. IFIS is an online tool that provides free, user-friendly access to “flood alerts and flood forecasts, more than 250 IFC real-time river and stream gauge sensors, more than 50 soil moisture/temperature sensors, flood inundation maps for 22 Iowa communities and rainfall products for the entire state.”

The center is also in the middle putting a $96 million federal grant to use through the Iowa Watershed Approach. The U.S. Department of Housing and Urban Development Disaster Resilience grant is currently funding flood mitigation and water quality improvement projects in nine Iowa watersheds.

State Representative Art Staed of Cedar Rapids serves on the Iowa Homeland Security and Emergency Management’s Flood Mitigation Board. Staed said, “We have repeatedly witnessed the devastating impact that floods have on our Iowa communities and it’s our responsibility as state lawmakers to work with local communities to minimize and mitigate flooding and the resulting damage to life and property.”

The proposed budget would not decrease funding for K-12 education, which is expected receive a 1.1 percent budget increase this year. However, it does eliminate $397,000 in state funding for the Iowa State University Leopold Center for Sustainable Agriculture.

IFC co-directors urged concerned citizens to contact state legislators to express support for the continuation flood center funding. They write, “This bill is expected to move very quickly so it is imperative you reach out as soon as possible.”

Conservation Reserve Program amended to support new farmers

The U.S. Department of Agriculture has modified a national conservation program in order to support beginning farmers.

Since 1985, the Conservation Reserve Program has paid farmers a yearly rent for removing environmentally sensitive land from agricultural production. Most contracts last 10-15 years. Previously, if farmers broke the contract early, they were required to return all the rental payments with interest. With the policy change, farmers may now end their contracts early without penalty if they sell or lease the land to a beginning farmer.

Agriculture Deputy Under Secretary Lanon Baccam announced the policy change, which will take effect January 9th, at the Joe Dunn farm near Carlisle in central Iowa. Dunn’s son-in-law, Aaron White, is a beginning farmer on a small acreage near Carlisle.

White said, “I think the biggest obstacle beginning farmers face is land access. This program would help alleviate some of those problems.” Lanon Baccam agreed, he said giving the next generation of farmers a chance at success makes perfect sense.

Signed into law by President Ronald Reagan in 1985, the Conservation Reserve Program is the largest private-land conservation effort in the country. It is unclear how the program’s stated goal of improving water quality, reducing soil erosion and protecting habitat for endangered species will be effected by putting environmentally sensitive land back into production for beginning famers.

UI News Services Release

With rising commodity prices bringing more farm land under cultivation, a University of Iowa researcher is checking to see whether soil erosion may also be on the rise.

Thanos Papanicolaou, professor in the UI College of Engineering Department of Civil and Environmental Engineering, has received a three-year, $642,000 federal grant through the University of Northern Iowa to study agricultural soil erosion and the carbon cycle in Iowa. Papanicolaou is also a faculty research engineer at IIHR-Hydroscience and Engineering with a secondary appointment at the Iowa Public Policy Center.

Funded by NASA, the Carbon Cycle program will test the development of methods and models of carbon budgets at a smaller, regional scale, which will eventually be applied at larger scales. The proposed analysis is a critical component of any system for determining carbon credits that may be developed in the future, according to Papanicolaou.

The project, involving collaboration between the UI, the University of Northern Iowa and the USDA National Laboratory for Agriculture and the Environment, investigates how soil erosion may be threatening climate mitigation policies within the state and Midwest.

“Recently, the production of bioenergy crops has surged due to U.S. government policies calling for an increase in locally produced biofuels to lessen United States dependency on foreign oil supplies and help mitigate the burning of fossil fuels,” said Papanicolaou. “For example, there is an increase in corn acreage, as well as cash corn prices, in the Midwest because of its use in ethanol production.
