In Iowa, deep-pocketed corporations are hoping to build carbon dioxide pipelines across hundreds of miles of farmland. But county governments are putting the brakes on development by passing ordinances to protect people in the pipelines' path. In response, Summit Carbon Solutions, the company farthest along in the state's permitting process, is punching back, filing federal lawsuits to overturn the ordinances and forcing counties to spend scarce taxpayer dollars to defend themselves.

Rewetting drained coastal evergreen shrub bogs in the Southeast that were once used for farming could make a small but significant contribution to reducing U.S. carbon dioxide emissions, according to a recent study. The bogs, known as pocosins, can absorb and hold extraordinary amounts of CO2 because they contain antimicrobial compounds called phenolics that prevent the waterlogged peat from decaying rapidly, even during times of drought.

In the debate over how to use agricultural lands to sequester carbon and help mitigate climate change, no-till and cover cropping get most of the attention. But studies are starting to show that grazed perennial pastures, where the soil is rarely disturbed and continuously covered, may be the best strategy for locking carbon in the soil long-term, according to experts on a recent Environmental Working Group webinar.

A major UN climate report released on Monday lays out a broad array of strategies for limiting emissions and mitigating climate change. While the most critical priority is to quickly phase out the use of fossil fuels, the report outlined many opportunities to help limit climate change by altering how land is managed and food is produced. And, critically, most of these options are “available and ready to deploy,” the authors wrote. (No paywall)

The USDA will spend $1 billion on climate-smart pilot projects, Agriculture Secretary Tom Vilsack announced on Monday, delivering on a pledge made last September to help farmers develop a market for sustainably produced commodities. The demonstration projects could change the shape of U.S. farm policy, but the clock already is ticking toward the 2023 farm bill and funding for climate mitigation is not certain.

Congress should substantially increase — as much as double — funding for USDA stewardship programs that encourage climate mitigation and help farmers make money from climate-smart practices, said a Washington think tank on Wednesday.

Only 5 percent of U.S. cropland is planted to cover crops amid debate over their financial benefits to farmers. Congress may need to offer a "sizable" subsidy to growers if it wants large-scale adoption of the farming practice, said two university economists.

Agribusiness giant ADM said on Tuesday it would reduce its carbon footprint by building a 350-mile pipeline to transport carbon dioxide for injection in central Illinois from its ethanol plants in eastern Iowa. It was the third carbon dioxide pipeline proposed for Iowa, the No. 1 corn and ethanol producing state.

A growing number of farmers, researchers and nonprofits are working to transform the Midwestern corn and soybean belt into a more diverse cropping region, including a new USDA-funded project at Purdue University designed to study how to help growers diversify their farms. (No paywall) 

In a carbon-neutral future, California’s farmers could plant water-conserving crops enriched by composting, the result of widespread carbon farming. Socially disadvantaged farmers could become more empowered. Farmworkers could be healthier and better paid. An ambitious report from the California Natural Resource Agency proposes major potential changes to the state’s agricultural sector in response to climate change. (No paywall)
