Wisconsin is part of a movement to reduce livestock emissions by converting manure into energy sources, and there are calls to weave in a careful approach.

Anaerobic digesters create biogas by removing methane from livestock waste. The gas can then be used for electricity, heat or vehicle fuel. Supporters say the process limits methane from reaching the atmosphere. The U.S. Department of Agriculture's Rural Energy For America Program helps fund these projects on farms in Wisconsin and elsewhere.

Andy Olsen, senior policy advocate for the Environmental Law and Policy Center, said the jury is still out on the effectiveness of digesters, and he urges the USDA to keep science in mind when considering the projects.

"There's how things work on paper and then, there's how things work on the ground," Olsen pointed out. "There's a lot of space in between the two."

Olsen argued the industry still needs to overcome challenges like methane leaks. Skeptics of the technology said among other things, federal funding incentivizes participating farms to expand their operations, creating more nuisance issues for surrounding communities. Still, Olsen noted the industry should be given time to address the shortcomings.

The Rural Energy for America Program also funds wind and solar projects on farm sites. Olsen noted there has been added support from the Inflation Reduction Act to expand outreach and technical assistance as a way to boost interest.

"I'm hoping to see a lot more good, energy-efficiency projects from that, which is the number-one place we should be starting," Olsen contended.

Olsen added improvements to grain dryers to help reduce natural gas use in harvesting are another example of energy efficiency efforts. As for digesters, a report from the Wisconsin Office of Energy Innovation said there are 136 operating systems around the state, with 34 tied to agriculture.

A meeting on sustainable fishing in Seattle could inspire greater protections for Washington state's waters in Olympia. The State Innovation Exchange held the "Sustainable Aquaculture and Working Waterfronts" convention with lawmakers from 13 states.

Emma Newton, senior associate with agriculture and food systems program for the State Innovation Exchange, said big corporations dominate agriculture and farming, but large-scale, industrial fish farming isn't in the United States - yet.

"However, we are seeing increased interest in putting these large-scale, essentially factory farms of the ocean in our waters, and they're a direct threat to our ocean ecosystems, our local fishers and the native fish populations," she said.

Newton added the convention focused on how policymakers can protect sustainable and local fishing economies and tribal food sovereignty.

Rep. Mia Gregerson, D-SeaTac, attended the convention and said the state banned some fish farming practices after tens of thousands of non-native Atlantic salmon escaped a fish pen in 2017. Gregerson added the state needs to go further to protect the region from industrial fish farming.

"We're only able to control the policy for about three miles off the shore, and so it's going to be really important then, right, to make sure that we have a state coastal zone management plan that prohibits the same type of farming beyond just state waters," she said.

Newton added events like the one in Seattle are important because policymakers are able to connect with communities and the people working on these issues, making them more effective in their decision making.

"They're able to know that they don't have to go to the large corporations or the lobbyists for the information they need. They can go directly to the community. They're building relationships that circumnavigate the traditional way that policy is being made," Newton said.

Farmers in Iowa are studying interactions between crops, water usage, carbon and nitrogen storage, and how those factors combine to affect longterm soil biodiversity. It's part of a seven-state project in the Midwest.

Researchers are looking at the effects of crop combinations on soil and moisture across the Corn Belt.

Iowa State University Agronomy Professor Sotirious Archontoulis is running one research site in the five-year, $16 million project.

He's monitoring how crop management, carbon and nitrogen content affect soil moisture - and will try to predict the impact on the viability of future crops.

"We have the same setup in many different environments to capture different organic matter, soil hydrology conditions," said Archontoulis, "so we get a better understanding of the complexities in the agronomic system."

Archontoulis said scientists can also study greenhouse gas emissions from the soil.

He said these ultimately affect its health and can have an impact on large ag operation waste runoff, which is known to pollute nearby ground and surface water. The research is gearing up now.

Based on the computer model's findings, Archontoulis said researchers can make recommendations to farmers based on - for example - how much nitrogen the soil is losing in certain places, and how they can adjust planting schedules as a result.

"We can say, 'This cropping system with this management practice typically loses that amount of nitrogen,'" said Archontoulis. "'However, the other combination of cropping system could reduce nitrogen loss and improve productivity by X%, so this is a better strategy to move forward.'"

Archontoulis said the research begins across the Midwest this summer.

Washington state has allocated nearly $1.5 million in grants to support local food systems and supply chains. The Washington State Department of Agriculture distributed the funds to 40 projects, supporting farmers, food and meat processors, and distributors.

Galen Van Horn, local food system and supply chain specialist with the Washington State Department of Agriculture directed distribution of the funds and said there has been consolidation in the large-scale market that small and mid-sized operations can combat.

"We've just seen a clear need for investment to support those small and mid-sized operations and make sure the infrastructure is scaled to meet their needs, and that we don't just have very, very large food system infrastructure - like processing facilities and aggregation points - that are only really scaled for very large farms and food businesses," he explained.

The seeds of the program began in 2021, when the Washington Legislature distributed federal COVID-19 recovery funds to support local food infrastructure because of the pandemic's impact on supply chains. Since 2023, the Local Food System Infrastructure Grant program has distributed $8 million in state funds.

Van Horn said the program is popular and received nearly $19 million in requests - well over what it could provide. One project selected in 2022 was the nonprofit Columbia Community Creamery, which received more than $450,000.

"They got a large grant to get the equipment necessary to receive bulk milk deliveries, and then process that into jars and have it ready to be consumed. A lot of food safety involved there," he continued.

The Washington State Department of Agriculture expects to start the next application round in the summer or fall of next year. Van Horn said the agency looks for proposals that impact the regional food system, are achievable and ask for a reasonable amount of money.
