Researchers have found the amount of land affected by saltwater intrusion on the Delmarva Peninsula has dramatically increased in recent years.

Scientists from the University of Maryland, the University of Delaware and George Washington University used aerial and satellite imagery, and found between 2011 and 2017, visible salt patches almost doubled and more than 20,000 acres of farmland had been converted to marsh. Researchers estimate the associated economic loss is between $39 million and $100 million.

Becky Epanchin-Niell, associate professor of agricultural and resource economics at the University of Maryland and the study's co-author, said farmers are responding to saltwater intrusion in different ways.

"Some farmers are continuing to crop and are going to just keep trying to farm for as long as they can. Others have tried switching to different crops," Epanchin-Niell outlined. "Certain crops are much more susceptible to the salinization and the inundation than others. Others have abandoned the cropland, and others have actually engaged in different conservation programs."

The paper was published over the summer in the journal Nature Sustainability. Epanchin-Niell noted researchers are now using the study results to attempt to predict areas where saltwater intrusion will next occur.

While sea level rise hits low-lying coastal areas first, there are also impacts to groundwater as well as farmlands connected to the coast via drainage ditches.

Epanchin-Niell pointed out the more northern portions of the Chesapeake Bay have lower salinity given the influence of rivers draining into the bay, so different areas will see differing levels of salinity even with a constant rise in sea level.

She added to prolong productivity of coastal farmlands, researchers are studying what kinds of crops are suitable.

"We also have a lot of work done looking at how different crops respond to saltwater intrusion and looking at how farmers have, and can in the future, adapt to saltwater intrusion," Epanchin-Niell emphasized.

Epanchin-Niell stressed researchers are also looking at developing methods to manage the transition with an eye toward the long term.

"If you abandon the farmland, and it became encroached with lots of invasive species, that's going to have fewer benefits than for example, if there's a more planned transition, where perhaps there's restoration with different wetland species that help with the inland migration of wetlands, which are also being impacted by sea level rise," Epanchin-Niell explained.

Dozens of union members rallied Wednesday in Sacramento, calling on lawmakers to pass a set of bills called the California Worker Climate Bill of Rights. The bills are intended to integrate worker's rights into the clean-energy transition.

The Climate Resilient Schools Act would create the first master plan to make sure our schools have clean, cool air, adequate shade and energy-efficient buildings and buses.

Jeff Freitas, president of the California Federation of Teachers, explained the importance of the bill.

"The bill also looks at everything that is needed," Freitas emphasized. "In terms of how it can help the state, how it can help the school environment and how it can help the students creating not only a more welcome space but a healthier space for our students and the workers there."

A second bill would require safety measures for workers at biofuel facilities. A third proposal would create a permanent fund for workforce development training -- with federal climate infrastructure monies coming -- and create labor standards for programs receiving federal dollars.

Amber Parrish, executive director of the Western States Council of the United Food and Commercial Workers union, said if we leave things to big business, the transition will mean unplanned layoffs, the creation of low-wage jobs and the decimation of the public sector.

"If we win strong labor standards in every emerging and shifting energy industry, we can ensure we have high-road jobs with family-sustaining wages and good benefits in green industries," Parrish contended.

The group is also calling for full funding in the new state budget to support workers displaced from the oil and gas industry. And the coalition opposes a measure on the November ballot called the "Taxpayer Protection and Government Accountability Act," which would put any future statewide tax increase on the ballot.

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.

State officials in Maine are highlighting apprenticeships as a way to earn a living wage and contribute to the state's growing green economy.

They'll kick off the first-ever Youth Apprenticeship Week by exposing high school students to the numerous ways they can learn and earn in offshore wind energy development, passive home construction, aquaculture, and more.

Maine Department of Labor Apprenticeship Program Manager Kristine McCallister said about 90% of apprentices choose to stay with their employer after their training is complete.

"Apprentices have a mentor and they're earning wages and they're earning pay increases as they go," said McCallister, "so it's a really great way to attract talent to Maine and to keep talent here."

McCallister said apprentices will earn $300,000 more over their lifetime. The state aims to add 75,000 more workers to the economy over the next five years by growing career training pipelines.

A report by the Maine Labor Climate Council finds the state can create tens of thousands of jobs by building a zero-carbon transportation system.

Workers will be needed to install EV charging stations, electrify school bus fleets, and potentially build a high-speed rail line from Bangor to Boston.

McCallister said new Mainers, like those studying with Portland Adult Education, are using apprenticeships to fill these roles and other clean-energy jobs.

"Those pre-apprentices just graduated and have interviewed with some of our apprenticeship programs," said McCallister, "so we're really hoping they're going to help feed that pipeline as this economy is booming in Maine in terms of the renewable-energy sector."

McCallister said some companies are even offering on-the-spot interviews and job offers this week. All apprenticeship events are listed on the Department of Labor's website.
