The Flood Recovery Advisory Board, formed by Governor Reynolds to coordinate statewide recovery and rebuilding following this year’s devastating floods, will gain  expertise from Larry Weber, a co-founder of the Iowa Flood Center.

Dr. Weber can offer valuable experience and insights in several areas related to flooding. He is a former director of IIHR Hydroscience & Engineering at the University of Iowa, conducting research in areas including river hydraulics, hydropower, ice mechanics, water quality and watershed processes.

Weber also conducts research for the UI Public Policy Center and worked with the state legislature in 2013 to implement the Nutrient Reduction Strategy. He and his wife have won several awards for conservation work on their own property.

Recently, he wrote an op-ed about his vision as leader of the U.S. Department of Housing and Urban Development’s $96 million Iowa Watershed Approach. This program addresses factors that contribute to Iowa’s increasing flood risk in nine distinct watersheds, with the ultimate goals of reducing risk, improving water quality and increasing resilience.

In the piece, Weber said he aims to restore natural resiliency through conservation measures like farm ponds, wetlands and terraces. Floodplain restoration is another important piece of his plan.

“We need to allow our rivers room to flood,” he said. “The floodplain is an integral, natural part of the river. They also keep people safe and remove us from the heartbreaking cycle that so many Iowans know all too well: Lose everything to a flood.”

His expertise in all-things-flooding, from hydraulics to conservation to policy, will surely prove valuable as Iowa begins to move forward from this year’s floods and better prepare for  flooding to come.

This weeks segment looks at BP’s place in the coming decades with rising demands for renewable energy.

Transcript:

BP Oil and Gas has made energy demand predictions about the future—but are they accurate?

This is the Iowa Environmental Focus.

After the massive oil spill along the Gulf Coast in 2010, BP became known globally in a decidedly negative light.

Almost a decade later, and with settlement payments still being paid out, the energy company has thrown its weight behind renewable energy. BP outlines in its annual energy outlook that the planet could run on mostly renewable sources by 2040.

There is a small detail that some environmentalists find troubling, however; the BP report also lists an estimated rising global demand for energy well into the 2040s, while other scientific reports estimate that global demand will taper off and even out by the 2030s.

A rising global demand for energy is a given, as underdeveloped countries begin working on their infrastructure and making improvements for their citizens. But overestimating how much energy will be needed globally in the future could allow oil companies to continue selling more fossil fuels, even as renewable energy use grows.

Iowa can count water contamination among flood damage

Julia Poska| March 28, 2019

Last weekend, President Trump approved Iowa’s $1.6 billion disaster declaration, to help cover flood damage to homes, businesses, farms and levees. Not accounted for is the cost of degraded water, now an issue in Iowa and across the Midwest.

The Gazette reported Monday that eight manure lagoons had overflowed in western Iowa. State Department of Natural Resources officials told the paper that conditions in the east had neared similar levels.  Manure overflow can harm aquatic life and contaminate water for drinking and recreation.

Manure spread onto fields also enters waterways when those fields flood, when snow melts and when it rains. One Buena Vista county feedlot operator may face DNR enforcement after spreading manure during three rainy days in March, the Gazette reported.

Unless a special waiver is granted, farmers cannot legally apply manure on snow covered ground December 21 through March. Farmers are anxious to get manure out of storage, and weather permitting, will be able to apply in coming days.

Manure, pesticides sewage and fuel in flood water could contaminate the 1.1 million private wells in 300 flooded counties in 10 states, as approximated by the National Ground Water Association. The Des Moines Register shared Tuesday an Associated Press report on risk to well water in the rural Midwest.

The risk of water seeping into wells heightens when water sits stagnant for days or weeks, as it has done since the floods. Liesa Lehmann of the Wisconsin DNR, told the AP that well owners should assume their water is contaminated if flood water sits nearby. She said to look out for changes in color, smell or taste.

Once flooding recedes, Lehman said, owners should hire professionals to pump out, disinfect and re-test wells.

 

 

 

 

On The Radio- Crops increasing, biodiversity decreasing

This weeks segment looks at decreasing biodiversity in crops around the world. 

Transcript:

The number of crops grown around the world has increased, yet crop biodiversity has declined. 

This is the Iowa Environmental Focus. 

Species richness, the number of unique species present in a defined area, often represents true biodiversity poorly. It discounts species evenness, which measures the relative proportion of each species’ population in the whole community. 

Even though 156 crops are grown globally — up from the mid-20th century — overall biodiversity is low because just four types of crops cover about 50 percent of cropland. A new study from the University of Toronto found that corn, rice, wheat, and soybeans dominate industrial agriculture around the world despite differences in climate and culture.

This impacts the affordability and availability of culturally significant foods in certain areas and leaves the global food supply increasingly vulnerable to pests and diseases. 

Increasing crop variety will make our food supply more resilient to pests and potentially reduce hunger.

Water quality researcher/blogger puts fresh perspective on stinking problem

This map from Chris Jones’ blog relates the “real populations” (based on animal waste) of Iowa watersheds to the human populations other global areas.

Julia Poska| March 21, 2019

The public rarely gets its science straight from the source; we depend largely on the media to distill complicated academic research for us. University of Iowa researcher and adjunct professor Chris Jones is one of a rare breed of scientists who can adeptly communicate science on his own.

Jones has spent his career monitoring and researching the Iowan environment for institutions ranging from Des Moines Water Works to the Iowa Soybean Association. As an IIHR research engineer today he conducts original research and runs a blog where he explores the systems and nuances surrounding Iowa’s degraded water.

Recently, Jones calculated “Iowa’s real population” based on the nitrogen, phosphorus and solid matter in animal waste. He explained that Iowa’s millions of hogs, cattle, chickens and turkeys produce as much waste as 134 million people. The map pictured above matches the human populations of global cities and U.S. states to the “real populations” of Iowa’s watersheds.

“Managing the waste from these animals is possibly our state’s most challenging environmental problem,” he wrote. Weather and plant life cycles create a limited time window to apply it to fields, and hauling and handling it presents other challenges. When nutrients from manure enter waterways, they contribute to harmful algae blooms locally and in the Gulf of Mexico.

In another recent post, Jones used public data to compare the amount of nitrate purchased commercially and produced via manure in each Iowa watershed with the Iowa State University recommended application rate for corn. He found that, on average, Iowa farmers over-apply synthetic nitrogen by 35 pounds per acre. The addition of manure brings that surplus to 91 pounds per acre.

Other posts explore historical, social and political angles. Earlier this week, a post called “Ransom” related efforts to protect Lake Eerie in Ohio to the economic reality of farming and agribusiness in Iowa. “Who is getting the outcomes that they want from our policies, and in particular, the old school policies targeting improved water quality?” Jones asked.

Overall, Jones’ blog offers an informative and rather accessible expert perspective on a hugely complex issue. To subscribe yourself, visit here and enter your email at the bottom of the left sidebar.

Iowa City Youth Climate Strike

Kasey Dresser| March 19, 2019

On March 15th across the nation, youths gathered to raise awareness for climate change and its effect on our world. In the Ped Mall in Iowa City, over 50 students from Southeast Jr. High gathered to speak to the community about their concerns.

The students came prepared with a bullhorn and took turns sharing their opinions for two hours. They were holding hand made signs and handing out a sheet of climate change facts. While young, the passionate students created quite an audience stating, “the bigger the fuss we make, the more politicians will listen.” Congressman Dave Loesback was present and talked with the students in his office following the event.

From the climate change fact handout:

  • 408 parts per million. The concentration of carbon dioxide (C02) in our atmosphere, as of 2018, is the highest it has been in 3 million years.
  • 800 million people or 11% of the world’s population is currently vulnerable to climate change impacts such as droughts, floods, heat waves, extreme weather events, and sea-level rise.
  • Thermometer records kept over the past century and a half show Earth’s average temperature has risen more than 1 degree Fahrenheit (0.9 degrees Celsius), and about twice that in parts of the Arctic.
  • We have 11 years to reverse the effects of climate change. We must act now.

On The Radio- Coffee Wake Up Call

This weeks segment looks at how deforestation is affecting coffee production. 

Transcript:

Deforestation and climate change may wipe out coffee worldwide. 

This is the Iowa Environmental Focus. 

Aaron Davis, a British botanist, has spent the last 30 years traveling across the world recording the patterns of coffee forests and farms. Sixty percent of coffee species are at risk for extinction due to the effects of climate change and deforestation. Coffee plantations are expected to vanish from the three major coffee producing continents.

Part of Dr. Davis’ research is the development of a barometer to test the biodiversity of forests and risks posed to coffee plants. The most popular coffee bean, arabica, comes from Ethiopia and has been shown to be extremely vulnerable to climate change effects. He reports that the ecosystems are becoming less diverse which mean less food and less shelter for species. 

While there are 124 coffee species, a majority are wild and inaccessible. Dr. Davis and the rest of his team continue their research to find rare coffee plants and new places to farm them. His travels have been directed toward cooler areas. On the teams’ most recent expedition, they found a hillside in Liberia covered in stenophylla, a flowering coffee plant that they are currently testing.

More research will hopefully ensure coffee is available long into the future.
