The FAO Food Price Index, based on prices of five groups of commodities - meat, dairy, grains, sugar and vegetable oil - has been on an upward trajectory since the start of 2016. Pushed by higher wheat and dairy prices, the index now has a reading of 175.2, the second time this year that it is on par with prices in February 2015, said the UN agency.

The U.S. stood alone at the G20 meeting in Hamburg, Germany, as all the other countries, including China and the European Union, called on the Trump administration to address climate change.

President Trump plans to appoint the Georgia state public health commissioner, Brenda Fitzgerald, as the director of the Centers for Disease Control and Prevention, said the Washington Post. Fitzgerald is president-elect of the organization representing public health agencies and "has strong ties to Republican leaders," including Health Secretary Tom Price, a former Georgia congressman, and former House Speaker Newt Gingrich, said the newspaper.

With the Trump administration pursuing a re-negotiation of NAFTA, Mexico is scaling back its purchases of U.S. corn, which has allowed Japan to become the top market for U.S. corn exports, said Bloomberg. Mexico has looked into corn imports from South America after President Trump made Mexico his chief NAFTA target and drove down the value of the peso.

Six state prosecutors from New York, Maryland, Vermont, Washington, Massachusetts and the District of Columbia are joining environmental and social advocacy groups in a lawsuit to push the EPA to ban the pesticide chlorpyrifos. "It is EPA's responsibility to protect Americans from unsafe chlorpyrifos residues on food because of the potential neuro-developmental and other adverse health effects caused by exposure," the prosecutors said in their filing, according to Reuters.

The United Nations’ UNESCO committee has voted to not add the Great Barrier Reef to its “in danger” list, despite the biggest die-off of coral ever at the World Heritage Site. "We're taking every action possible to ensure this great wonder of the world stays viable and healthy for future generations to come,” Australia's Energy Minister Josh Frydenberg told Australian Broadcasting Corporation Radio.

The EPA is recruiting experts to review climate-change findings, says a senior agency official, in what may be the latest attempt to undermine climate change efforts. “The program will use ‘red team, blue team’ exercises to conduct an ‘at-length evaluation of U.S. climate science,’ the official said, referring to a concept developed by the military to identify vulnerabilities in field operations,” reports E&E News.

Two migrant farmworkers have filed a federal class action lawsuit against Monsanto, alleging that the company violated the Fair Labor Standards Act and the Agricultural Workers Protection Act while the workers were employed in Monsanto’s GMO seed corn fields.

Two years ago, world cotton production was the lowest in 13 years, due to smaller plantings and plunging yields. This year, the world will produce 14 percent more cotton than in 2017 for a harvest of 24.6 million tons that will drive down the season-average cotton price by 13 cents a pound, says the International Cotton Advisory Committee.

Famine often starts in rural areas and must be prevented in rural areas, said the UN Food and Agriculture Organization in a report on hunger in Nigeria, Somalia, South Sudan and Yemen, collectively one of the world's largest food crises in 70 years. Some 20 million people in the four nations are at risk of famine, a figure that could grow to 30 million if there is no additional action, said FAO.

Farmers and ranchers say they are in a better financial situation than a year ago, according to the Ag Economy Barometer's monthly survey.

Dairy farmers in three counties in California's Central Valley have temporary permission from local officials to bury or compost hundreds of cows that died in a June heat wave, says the Fresno Bee. Ordinarily, the dead animals would be sent to a rendering plant, but there are too many carcasses and a mechanical malfunction reduced the plant's capacity.

EPA administrator Scott Pruitt "has moved to undo, delay or otherwise block more than 30 environmental rules" in his four months in office, a larger rollback in so short a time than the agency has ever seen, says the New York Times. While the Trump agenda has stumbled in many areas, all sides agree that Pruitt "is moving effectively to dismantle the regulations and international agreements that stood as a cornerstone of President Barack Obama's legacy," said the newspaper.

Congressional and food-aid groups say the White House quickly dropped plans for an executive order to put all U.S. food aid on U.S. flagged vessels, reported Reuters. The idea gained some support as an America First initiative but foes said it would drive up shipping costs and thereby reduce the volume of food delivered to needy areas.

Some 646 million people are food insecure, with diets of less than 2,100 calories a day, in the 76 low- and middle-income nations that are current or traditional food-aid recipients, says the USDA in forecasting a dramatic improvement in the decade ahead.
