Three decades into the agricultural biotechnology era, the USDA said on Thursday that it will exempt genetically engineered plants from pre-market reviews if they are unlikely to pose an environmental risk. Opponents of the move said it means "a majority of genetically engineered and gene-edited plants will now escape any oversight" by the USDA.

A government decision to deregulate gene-editing tools such as CRISPR met a last-stop challenge in the Australian Senate, with an organic farmers’ group expressing concerns that it will be “sacrificed for the sake of unregulated GMO tech.”

Four consumer groups and the United Food workers union asked the White House to expedite the creation of the catfish inspection program, now six years past due.

The Agriculture Department announced a $91 million loan guarantee for an advanced biofuel plant in Rapides Parish, Louisiana, that will turn pine chips into 8-10 million gallons a year of reformate, a drop-in ingredient for gasoline and jet fuel that can be added during the regular refinery process.

Landowners enrolled in the Conservation Stewardship Program, which pays farmers to practice soil, water and wildlife conservation as part of their daily operations, will have two months to apply for a renewal of their contract, says a USDA bulletin.

Throughout the pandemic, the highest Covid-19 case rates and the lowest vaccination rates in the country have been found in persistently poor rural counties, the USDA said Wednesday in its annual Rural America at a Glance report. Those counties have also had low unemployment rates, suggesting residents continued to work despite the risk of infection by the coronavirus, said the report.

The rural poverty rate has exceeded the urban rate ever since the government began tracking both in the 1960s. The difference, 4.5 percentage points in the 1980s, has narrowed to an average of 3.1 points over the past 10 years, said the USDA in updating its rural poverty and well-being webpage.

Although the House Agriculture Committee's name screams "rural," three of its new members are urban Democrats: Reps. Bobby Rush from Chicago, Ro Khanna from Silicon Valley, and Luis Correa from Orange County, California.

Central Iowa’s Dallas County is growing rapidly as the Des Moines metropolitan area spreads westward, says Harvest Public Media in a look at life in two midwestern counties where rural is meeting urban.

First Lady Melania Trump, who toured Japanese-inspired gardens in Florida with the wife of Japanese Prime Minister Shinzo Abe, intends to keep the kitchen garden planted by Michelle Obama in 2009. An adviser told CNN, "As a mother and as the First Lady of this country, Mrs. Trump is committed to the preservation and continuation of the White House Gardens, specifically the First Lady's Kitchen Garden and the Rose Garden."

After she leaves the White House, First Lady Michelle Obama will continue to advocate for healthy food for children through the non-profit Partnership for a Healthier America (PHA), which works with food companies to improve nutrition content of food products and on labeling, Reuters reported.

Blood samples from five healthcare workers in Missouri will be tested for exposure to the avian flu virus, said the Centers for Disease Control in a weekly update on bird flu. The workers developed mild respiratory symptoms while involved in treatment of a patient infected with the H5N1 virus but who had no known contact with animals.

The corn earworm is a widespread crop pest, particularly in the U.S. South, and adept at quickly developing resistance to genetically engineered crops. Over time, researchers looking at lab-selected strains of earworm have identified 20 genes that harbor mutations conferring resistance to pest-killing proteins in so-called Bt crops, which have been genetically engineered to produce bacteria that repel the earworm.

As the climate warms and the world’s oceans take up more carbon dioxide, those waters are becoming increasingly acidic, causing damaging corrosion to the shells of many marine species, including oysters.

The supermarket tomato, bred to resist bruising, could gain improved flavor thanks to Chinese and U.S. scientists who found a genetic roadmap to the genes that determine the taste of tomatoes, says the Wall Street Journal. Tomatoes are not native to China but the Asian nation has been the world’s largest grower of them since 1995.

A team of scientists from Argentina, Brazil, Mexico, and Spain has deciphered the genome of the Mesoamerican common bean (Phaseolus vulgaris), according to Spain's Center for Genomic Regulation. The findings are reported in the current issue of the journal Genome Biology.

Russia is exporting more grain at higher prices than ever before while suppressing Ukrainian shipments, said Secretary of State Antony Blinken at a UN Security Council meeting on Thursday. “Every member of this council, every member of the United Nations should tell Moscow: Enough using the Black Sea as blackmail, enough treating the world’s most vulnerable people as leverage.”

The lean years following collapse of the agricultural boom in 2013 are "raising concerns that the next few years could bring the biggest wave of farm closures since the 1980s," says the Wall Street Journal in a story headlined, "The next American farm bust is upon us."

Biofuels are far more responsible for high vegetable oil prices than Russia's invasion of Ukraine, said agricultural economist Aaron Smith of UC-Davis, and the biofuel industry will drive up vegetable oil prices further. Ukraine and Russia produce more than half of the sunflower oil in the world but the oil accounts for only 10 percent of global production of vegetable oils.

The United States will export a record $191 billion worth of agricultural products this fiscal year as the world scrambles to replace the corn, wheat, and vegetable oil it would normally get from Russia and Ukraine, said the Agriculture Department on Thursday. It would be the second year in a row of record-high farm exports.

The Russian invasion of Ukraine focused world attention on wheat prices and disruptions of supplies to poor countries that rely on imported grain. Now analysts at the IFPRI think tank say there is “another important emerging food security issue: the war’s impact on vegetable oils.”

Secretary of the Interior Ryan Zinke has reversed plans to transfer control of the National Bison Range to the Bureau of Indian Affairs. When tribes called for the change in 2016, they claimed the federal government had taken the land from American Indians without their consent.

One of the largest cullings in a decade is planned for the bison herd at Yellowstone National Park, says Reuters. Plans call for animals that stray outside the park boundaries to be targets for hunters and for the animals to be herded to tribal land for slaughter.

Nearly hunted to extinction in the late 1800s, the North American bison is now the national mammal, thanks to President Obama's signature to enact HR 2908, the National Bison Legacy Act. The new law declares the woolly, 2,000-pound bison "a historical symbol of the United States."

The bison will soon join the bald eagle as America’s national animal—and its only mammal, says The Guardian.
