A Harvard School of Public Health study looked at how more carbon dioxide in the atmosphere affects nutrient levels in six primary food crops: wheat, rice, field peas, soybeans, corn and sorghum. The researchers split plants of the same crop up between two groups. The first group was cultivated in an environment with between 363 and 386 parts per million carbon dioxide (CO2). This was the amount of CO2 in the atmosphere at the time of the study, in 2014. The second group of plants grew up in an environment with between 546 to 586 parts per million of the greenhouse gas in the air. This is roughly the concentration of CO2 expected to be in Earth’s atmosphere within fifty years.
When it was time, the scientists harvested the crops and measured levels of key nutrients in them. They looked specifically at zinc, protein and iron. The study found that plants grown in environments with higher concentrations of CO2 were less nutritious than their counterparts. Wheat, rice and soybeans were all found to have lower levels of zinc, protein and iron in the higher CO2 conditions.
Animal products are the primary source of protein for most people in the U.S., but people in other parts of the world rely heavily on rice and wheat as their main protein providers. These foods are naturally low in protein and further deficiency could be devastating. One study in the Journal Environmental Health Perspectivesfound that these projected impacts could cause an additional 150 million people worldwide to be protein deficient by 2050. Protein deficiency can cause low birth weight and other health problems that stunt growth and development.
The state of Iowa was ranked 18th in 2017, a far cry from its second place ranking in 2012. Iowa has slid down the list each year, ranking 10th in 2014, 13th in 2015, and 14th last year. According to this year’s report, Iowa ranked in the top ten for farmers markets per capita and community-supported agriculture per capita. However, the state ranks 50th for local food-to-school programs. Iowa performs in the middle of the pack when it comes to direct farm-to-consumer sales and USDA local food grants per capita.
The 2017 index features a new metric: hospitals sourcing local foods relative to the state’s population. Hospitals and local food organizers in Vermont have led the way, but the report notes that healthcare centers across the country have been pushing for 10 to 20 percent locally-sourced food in recent years.
Steven R. Gordon is President and CEO of Brattleboro Memorial Hospital in Brattleboro, Vermont. He said,
“Brattleboro Memorial Hospital is proud to be a leader in supporting local farms and producers of fresh and healthy food. Sourcing local produce not only supports our local economy but also helps our patients heal faster. Often times, when a person is ill or on various medications, their appetite diminishes and their tastes are altered. Providing our patients with in-season and locally-produced food allows us to provide meals with high flavor and nutrition.”
The state of Iowa ranked just inside the top 20 for local foods served in hospitals. The Vermont Association of Hospitals and Health Systems explains their journey to a more sustainable food system for hospitals and the benefits they’ve reaped thus far in the video posted below.
While the pantry is still an outreach ministry of the North Liberty church, its facilities are hardly comparable to the organization’s modest beginnings in 1985. The pantry is now housed in a modern building that features a client-choice shopping model. The building also features refrigerated and frozen food capacities, which is all part of the pantry’s mission to offer clients equal access to wholesome foods like vegetables, fruits, meat, and dairy. Executive Director Kaila Rome explains, “Everyone deserves to have the option of healthy nutrition choices, along with the access to knowledge and resources to implement healthy eating.”
Two years ago the pantry expanded that effort through the establishment of the North Liberty Community Pantry Growing Together Garden. The pantry received a Gardening for Health grant through the Wellmark Foundation’s initiative to provide healthier options to people experiencing food insecurity. The grant was matched by North Liberty community donations and provided funds for a paid garden coordinator, necessary equipment, and installation. The 9,600 sq. ft. garden is situated just west of the pantry and provided just over 800 pounds of organically grown produce for pantry goers last year.
When produce from the garden hits the pantry shelves, it is often accompanied by cooking instructions and other foods that pair well with it. “We’re still small enough where we get personal interaction with almost every family, or at least we try to, where we can ask them, ‘Hey, have you tried this recipe?’ What worked and what didn’t, people will bounce ideas off of each other so it’s been really great to see that just from having fresh produce. It’s just one of those things that you don’t think can bring people together, but I think it has,” said Rome.
Garden and Volunteer Coordinator Ilsa Dewald also provides more pointed skill-building through the organization of salsa and canning classes for families. Both community members and pantry families attend classes, encouraging cohesion among North Liberty residents. Rome added, “There’s just a big co-mingling of individuals from people who have used our services, maybe need to use our services in the future to people who just stop by the pantry to pick up their CSA [Community Supported Agriculture] share.”
In combination with donations from local farmers, the pantry is able to provide about three pounds of produce to clients per pantry visit. Rome said, “Just because someone is in need doesn’t mean that their needs change, they still need vegetables, they still need produce, they still need meat and dairy items…We’re not just handing out cans of beans and canned soup, but it’s more than that. It’s about giving back, even if you’re receiving services here, people will volunteer in the garden and it really helps them feel like they are able to contribute.”
The Growing Together Garden does more than provide families with the health benefits associated with eating more vegetables and fruits. It also provides a model of a local food system that is not only reserved for those with an abundance of resources such as arable land, start up money, and leisure time, all while curbing greenhouse gas emissions associated with conventional food systems. The garden’s food equity work is echoed by fellow non-profit group Grow: Johnson County, which was recently leased two acres of county land by the Johnson County Board of Supervisors to combat food insecurity and promote health through a garden education program. The organization grows vegetables exclusively for hunger-relief programs like Table to Table and The Crisis Center and provides garden education to disadvantaged populations. Grow: Johnson County’s Education Director Scott Koepke commented on the North Liberty Garden Project during its infancy, “This is not your typical garden. This is designed to be sustainable for years to come, and large enough to provide food for hundreds of people.”
With home and community gardens on the rise, up 200% since 2008, it seems projects like these will only continue to pick up steam; which, according to Koepke is a good thing, “Food insecurity isn’t going away anytime soon.”
Released on July 1st, the U.S. 2030 Food Loss and Waste Reduction Goal: A Call to Action by Stakeholders seeks to galvanize farmers, food manufacturers, grocers, consumers, and policy makers to reduce food waste by 50 percent before 2030. The initiative outlines best practices as identified by stakeholders including the creation of markets for aesthetically unappealing produce, implementation of community composting systems, and the development of new food storage technology that would prevent spoilage. The document is the direct result of a Food Recovery Summit that was held last November in Charleston, South Carolina.
Jordan: “Fifteen percent of what goes into the Iowa City landfill is food waste so the city is definitely on board with efforts to help individuals and businesses reduce food waste, and not only to save the food waste from going to the landfill but to save money as well.”
Participation in the national 50% reduction goal is voluntary, but states like Massachusetts and Vermont have already instituted commercial food waste bans. Food waste makes up a majority of U.S. landfills and quickly generates methane, a potent greenhouse gas. EPA notes that food loss reduction would help to mitigate climate change, address food insecurity, and save producers money.

Citing environmental concerns associated with livestock production, the federal government’s newest round of dietary guidelines may be broadening its scope to include sustainably-produced foods.
The U.S. Dietary Guidelines Advisory Committee, a partnership between the U.S. Department of Agriculture and the U.S. Department of Health & Human Services, reviews current dietary guidelines every five years, concluding in a list of dietary recommendations which affect federally subsidized school lunches, food labels and the government’s Choose My Plate program, which replaced the food pyramid in 2011.
A draft recommendation at the committee’s December meeting suggested a shift in the amount of red and processed meats Americans consumed, perhaps due to the significant role livestock plays in human-induced greenhouse gas emissions: As much as 14.5% of emissions may come from livestock, with beef making up a large portion of the total. Promoting a more plant-based diet on environmental grounds could lead to reductions in agricultural emissions as well as ensure food security for future generations. More sustainable livestock production practices could also have a significant impact on the country’s water quality.
While the panel’s draft recommendations have already received backlash from livestock groups, the committee maintains there is “compatibility and overlap” between food sustainability and human health.
This week’s On the Radio segment looks at a new study which suggests global warming greatly increases the odds of a global food crisis in coming decades. Listen to the audio below, or continue reading for the transcript.
Transcript: Food Crisis – Maggie St. Clair
New research from Stanford University and the National Center for Atmospheric Research suggests that climate change has greatly increased the odds of a crisis in global food production.
This is the Iowa Environmental Focus.
The study, titled “Getting caught with our plants down,” is meant to serve as a warning to institutions affected by fluctuation in food prices.
The study’s authors allow that the prospect of a major slowdown of corn and wheat production in the next few decades is low. However, they say that the chances of such of an event multiply by twenty times when global warming is factored in.
In this model, the trend of increasing food production would continue, but the rate of increase would drop substantially. This change would clash with global food demand, which is expected to keep rising.

The new farm bill, passed by Senate last week will affects Iowans in several ways, from boosting access to locally grown fruits and vegetables at farmers markets to protecting wetlands and prairies, the Des Moines Register said.
Here are six ways the farm bill impacts our state directly:
