Climate change to cause chocolate scare

Trick-or-treaters will bound from door-to-door this evening hoping to take home one of the world’s sweetest treats: chocolate.

While Halloween may feel like business-as-usual tonight in Iowa, chocolate producers across the globe are feeling the heat of climate change.

Chocolate is made from cocoa beans, which can only be cultivated very close to the Earth’s equator. This part of the world provides little temperature variability, lots of humidity and rain, nitrogen-rich soils and protection from wind that cacao trees need to thrive. Most of the world’s chocolate comes from cocoa beans grown in Côte d’Ivoire, Ghana, and Indonesia.

If the climate change continues unabated, these regions of the world are expected to warm by  3.8°F before 2050. It’s not necessarily the heat that will hurt cacao trees, it’s a decrease in humidity. About two-thirds of the world’s chocolate comes from Western Africa, where precipitation is not increasing to offset the effects of a hotter climate and drought has been a major problem in recent years.

Kevin Rabinovitch, a spokesperson for Mars, Incorporated, told Yale’s Climate Connections, “As temperatures rise and rainfall patterns change, some of the current cocoa-producing regions may become less suitable for producing cocoa.”

Rising temperatures and less rainfall may push cocoa growing operations in Côte d’Ivoire and Ghana up some 800 feet in elevation in order to keep up with demand, according to NOAA.

For its part, Rabinovitch explained that Mars is taking steps to reduce carbon emissions from its products by 67 percent before 2050. Cacao farmers are adapting to drought and temperature spikes by selectively breeding more drought resistant crops and planting cacao trees under taller rainforest trees for shade cover.

Tom Vilsack will deliver a lecture at Iowa State University as a part of the National Affairs Series: “When American Values Are in Conflict” next month.

Vilsack served as Governor of Iowa from 1999 through 2007. His lecture, titled “Agriculture and Climate Change,” however, will center more around his work as Secretary of the U.S. Department of Agriculture (USDA) during the Obama administration. As USDA Secretary, Vilsack helped to develop and manage programs related to rural electrification, community mental health and refinancing farm homes, to name a few. He also managed the federal school lunch program and the Supplemental Nutrition Assistance Program (SNAP).

Vilsack currently serves as president and CEO of the U.S. Dairy Export Council, “a non-profit, independent membership organization that represents the global trade interests of U.S. dairy producers, proprietary processors and cooperatives, ingredient suppliers and export traders.”

Additional details about the lecture can be found here.

Jenna Ladd | October 24, 2017

A statewide conference titled “Clean Water-Livable Communities” is scheduled to take place in Fairfield, Iowa on Thursday, November 9th from 9:00 am to 4:00 pm.

The conference will center around strategies to make clean water a top economic priority in Iowa. Four panel sessions are scheduled including: Iowa Water Overview; Robust, well-managed soils create clean water; Funding our clean water solutions; and Economic opportunities that result from clean water.

John Ikerd will be featured as the day’s keynote speaker. After receiving his PhD in Agricultural Economics from the University of Missouri, Ikerd worked in traditional agriculture for about a decade before he shifted his focus to sustainable agriculture during the farm crisis of the 1980’s. Since then, the Missouri-native has published six books about sustainable agriculture and economics, including Sustainable Capitalism: A Matter of Common Sense and Small Farms are Real Farms: Sustaining People Through Agriculture. Ikerd now lives in Fairfield, Iowa and co-teaches a Sustainable Economics course at Maharishi University of Management.

The conference is organized by the American Sustainable Business Council, Iowa Natural Heritage Foundation, Southeast Iowa Food Hub and the Iowa Chapter of the Sierra Club. Tickets will be available soon at http://www.fairfieldacc.com/site/buy-tickets.html.

On The Radio – Petition to strengthen regulation for livestock operations denied

This week’s On The Radio segment discusses how a recent attempt to strengthen regulatory standards for livestock facilities in Iowa was shut down by the Iowa Environmental Protection Commission. 

Transcript: A petition to make it more difficult to build animal feeding operations in the state of Iowa was recently denied by the Iowa Environmental Protection Commission.

This is the Iowa Environmental Focus.

Under current law, applicants seeking to construct livestock facilities must meet only 50 percent of the state’s master matrix of rules and regulations pertaining to the structures. The petition, filed by two environmental groups, Iowa Citizens for Community Improvement and Food & Water Watch, requested that applicants meet at least 86 percent of the matrix’s requirements.

The Iowa Department of Natural Resources sided with the Iowa Environmental Protection Commission and recommended against passing the petition, both groups said that the proposed changes would be too stringent. Proponents of the petition pointed out that just two percent of applicants are denied permission to construct livestock feeding operations in the state of Iowa.

The current animal feeding operation master matrix was developed fifteen years ago by state lawmakers.

ISU Horticulture Research Station celebrates anniversary

Jenna Ladd| September 22, 2017

Iowa State University’s Horticulture Research Station celebrated its 50th anniversary this week.

The anniversary was marked with a farmer’s market, farm tours, children’s games and a produce washing demonstration on Saturday.

The 235 acre station is home to 80 to 90 research projects each year. Scientists from horticulture, forestry, botany, ecology, plant pathology, entomology and natural resources use the space to study everything from vegetables to honeybees to wasps to swallows. The land bears apples, pumpkins, watermelon, hops, grapes and more.

Ben Pease is a Horticulture Research Associate at Iowa State. He said, “We are able to sell most of what we grow. If it’s part of a research project once it’s done we can sell it or we’re growing stuff to use the land we’re able to sell it,” to Iowa State Daily. Pease added that the station has made over a million dollars selling produce since 2006. Much of the food is sold to ISU’s dining halls, which buys about 5 tons of green peppers each year.

The land, which features a 15 acre lake as well, is located just three miles north of Ames on highway 69.

Iowa farmers face low yields, low prices

Katelyn Weisbrod | August 16, 2017

Nearly half of the state is in a drought this summer, and Iowa farmers are struggling to make ends meet.

A Des Moines Register report showed thousands of Iowa farmers are not seeing enough rain this summer, while crop prices remain low and farm income continues to trend downward. Corn and soybean prices are down 10 percent from July, and this year, farm income is expected to fall $62 billion nationwide.

“The drought isn’t widespread enough to push up prices,” Charles Brown, an Iowa State University farm management specialist said to the Register. “It’s the worst-case scenario — low prices and low yields.”

Some farmers have crop insurance to cover their losses, but often, it’s not enough. Many rely on savings to get them through after a tough year.

The drought is also drying up pastures, eliminating a dependable food source for cattle. Some farmers use hay to supplement the animals’ diets. And if a farmer’s crop has a low yield unworthy of harvesting, the farmer may choose to chop it into animal feed instead of trying to sell it.

There is still time for rainfall to improve the outlook for Iowa farmers’ crops this season, however, some are losing hope.

“People get frustrated. They throw up their hands and don’t do anything,” Brown said to the Register. “But now isn’t the time to procrastinate. [Farmers] need to get a plan together.”
