New research from the University of New Hampshire could help dairy farmers increase profits while reducing their effect on the climate.

Scientists said adding a plant-based essential oil blend to cow feed can improve a cow's digestion and reduce the release of methane, a potent greenhouse gas.

Andre Brito, associate professor of dairy cattle nutrition and management at the University of New Hampshire, said the findings are especially true for pasture grazing cows and shows a happy cow makes for a healthier environment.

"If those animals are provided those conditions, they'll be more productive," Brito pointed out. "Then the amount of methane that's being emitted by those animals is diluted because they're producing more product."

Brito reported adding the plant oils led to a more than 6% increase in milk production, which is good news for the majority of New Hampshire dairies, especially small to mid-size operations with smaller profit margins and higher equipment costs.

Still, Brito noted the research findings could translate to larger, industrial-size dairies. The factory farms often hold thousands of cows, generating significant methane emissions through their hearty burps and manure, which is often stored in large, polluting lagoons.

Brito acknowledged although the plant-based oils are readily available for use, farmers must weigh the economic benefits and overall environmental impact.

"Any investment that the farmers would make in a product has to be tied to economics," Brito stressed. "Even though farmers overall, they are conscious about the environment and they want to make sure that there is less carbon, nitrogen footprint out of their farms."

Brito's research was conducted on cows as they transitioned from the winter indoor-feeding schedule to eating their favorite plants in the pasture, a diet change which can increase the cow's emissions.

Brito added he hopes the research can help farmers better understand when to add the oils to the cow feed to potentially reduce the cow's overall climate effect.

School districts and county governments across Texas are being encouraged to consider building decarbonization to combat climate change.

The process reduces or eliminates carbon emissions in buildings by making energy efficiency improvements. According to a report by the Texas Climate Jobs Project, existing structures are a large contributor to carbon emissions, adding as much as 40% to the total worldwide.

Sandra Bustillos, the organization's carbon-free and healthy-buildings coordinator, said the report focuses on three main areas of improvement.

"There's the utility savings aspect of it," she said. "The next one is job creation, so we really abdicate for the creation of high-quality, family sustaining jobs. And then lastly, we also discuss health benefits."

She said Americans spend 90% of their time inside buildings that have carbon emissions that could impact their heart and lungs. They found that retrofitting all the public schools in Texas could boost the economy by creating up to 84,000 jobs.

The report shows that making small changes like installing solar panels, upgrading windows and doors and enhancing insulation can improve building efficiency and reduce emissions. Bustillos says the impact of climate change has been evident in recent weather events across the state.

"Hurricane Beryl this past year or four years ago Winter Storm Uri. It had really deep impacts on our communities - whether that be environmentally, socially or financially. So, I think it's urgent to be thinking about the effects of climate change and it's also urgent to be thinking about how we can create resilient buildings. "

The report found that rising heat also threatens the local economy and natural resources. Experts warn that a changing climate is likely to reduce water availability in the state, which will impact farmers' ability to grow crops.

For generations, small family farms have worked to feed Mississippi communities but small-scale operations, particularly those run by Black farmers, face growing challenges in a landscape increasingly dominated by large agribusinesses.

The struggles are not new. Systemic barriers to getting loans and resources continue to disadvantage Black farmers.

Henry Bell, co-owner of Old Country Farm in Jefferson County, said his father started farming in the 1930s. Now working alongside his daughter, they focus on sustainable livestock farming and seasonal crops, like berries and sweet potatoes. Bell pointed out challenges like delays in loan disbursements have directly affected their planting schedules.

"You know, you have growing season and all that. You miss that growing season then you've got to wait to start the next year, and of course that put us back behind the white farmers," Bell explained. "The white farmers, they always got their money on time and most times, they got more money than they need."

Bell worries corporate farms "get the best of everything," compared to smaller operations. Last year, the Biden administration provided more than $2 billion in direct payments to Black and minority farmers who faced discrimination from the U.S. Department of Agriculture.

Climate change adds new threats. The Bells remember the devastating 2001 freeze, which wiped out their livestock and severely affected the farm.

Brittany Bell Surratt, co-owner of Old Country Farm, said extreme weather, from intense heat to sudden freezes, continues to disrupt their operations.

"The South shouldn't get that cold. But at the same time, we are also seeing these extreme heat temperatures, to the traditional climate change point, in which you have long periods of droughts," Surratt observed. "So, there's not rain that's coming, to be able to have the grass and to fertilize."

Many small Mississippi farms also struggle with the digital divide. Surratt noted her father remains largely disconnected from modern technology, operating mostly off the grid.

"They don't have Wi-Fi at his house," Surratt added. "There's a technology divide that is shutting out rural and older farmers where they are not being able to get the information that's needed when these types of climate disaster do happen and there may be sometime of relief."

Despite the challenges, the Bells said they are dedicated to sustainable farming and advocating for policies to support small farms, including race-based programs to address historical discrimination.

They also want to inspire younger generations to take pride in farming. In 2018, Bell's granddaughter made history as the first African American girl in the area to win the "Dairy Goat Queen" title at the local fair.

Energy costs in Maryland are higher than the national average and one proposal to address the issue is facing backlash from environmentalists.

Top Democratic leaders in the Maryland General Assembly said building more dispatchable power plants would help solve this issue but environmentalists are not convinced. Dispatchable power plants are facilities which can be turned on and off to produce power to match the required demand. Sometimes, it refers to natural gas plants.

Mike Tidwell, executive director of the Chesapeake Climate Action Network, pointed out Maryland has a goal of net-zero carbon emissions by 2045. A natural gas plant, he said, would only push Maryland farther from its goal.

"We've steadily been moving in the right direction with wind power, with solar, with energy efficiency," Tidwell outlined. "Building new gas plants in the 2020s, with sea level rise affecting downtown Annapolis, is just tragically bad public policy."

A recent study from Google found new gas power plants were the least economically efficient way to meet the energy needs of Maryland. Dispatchable power plants can include zero-emission sources, like nuclear power plants.

Instead, virtual power plants were the most cost and environmentally efficient way to meet the demands of the Bay state. Virtual power plants involve a network of small-scale energy resources like solar panels, batteries and smart appliances connected as a single unit.

Tidwell noted his organization has not seen data to support the economic or environmental arguments for a new natural gas power plant. The opposite goes for renewables, he pointed out.

"There is a lot of real-world data showing and other data showing that you can build batteries, you can improve efficiency and you can build solar power much faster at a cheaper cost," Tidwell emphasized.

The smaller sources of energy from virtual power plants can have their energy outputs adjusted to meet demands.
