Agroecology is Advancing Around the Globe. Will the U.S. Take Part?

With its strong focus on social change for small farmers, agroecology is going mainstream worldwide, but the American food movement has yet to catch up.

Earlier this month, the United Nation’s Food and Agriculture Organization (FAO) held the 2nd International Symposium on Agroecology at its headquarters in Rome. The gathering attracted almost 800 participants, with representatives from 72 governments and 350 “non-state actors,” including civil society, academia, and the private sector. Farmers from Senegal, academics from the U.S., French parliamentarians, and staff of CropLife International, among others, gathered to debate the FAO’s claim of the urgent need to “scale up” agroecology as a means of achieving a more sustainable food system.

The symposium, hosted by the preeminent global institution on food issues, suggests that agroecology may finally be moving out of the margins. And it’s in the process of being mainstreamed.

Yet here in the U.S., it’s a different story. In fact, the word is rarely heard, even among people concerned with both agriculture and ecology. Instead, advocates—and the food industry—use the words organic, sustainable, and regenerative. And while some seem to use agroecology as an umbrella term that encompasses all of these practices, it’s more complex than that.

Shifting Language

All the above-mentioned terms share a commitment to food production without negative impacts on the environment. What makes agroecology different, potentially, is the combination of its scientific bona fides and its rootedness in the practices and political organization of small-scale food producers from across the globe. The former—as seen in multiple scientific elaborations of agroecology’s principles, like improved soil health, crop rotation, and diversification—is complemented by the latter, which gives agroecology meaning beyond the combination of “ecological” and “agriculture.”

One of the most worrisome predictions about climate change may be coming true

Two years ago, former NASA climate scientist James Hansen and a number of colleagues laid out a dire scenario in which gigantic pulses of fresh water from melting glaciers could upend the circulation of the oceans, leading to a world of fast-rising seas and even superstorms.

Hansen’s scenario was based on a computer simulation, not hard data from the real world, and met with skepticism from a number of other climate scientists. But now, a new oceanographic study appears to have confirmed one aspect of this picture — in its early stages, at least.

The new research, based on ocean measurements off the coast of East Antarctica, shows that melting Antarctic glaciers are indeed freshening the ocean around them. And this, in turn, is blocking a process in which cold and salty ocean water sinks below the sea surface in winter, forming “the densest water on the Earth,” in the words of study lead author Alessandro Silvano, a researcher with the University of Tasmania in Hobart.

7 things we’ve learned about Earth since the last Earth Day

Our understanding of Earth — and how we’re changing it — just keeps expanding.

Earth Day turns 48 today, April 22, and Google is celebrating it with a Google Doodle of conservationist Dr. Jane Goodall, who nudges us in a video a “do our part for this beautiful planet.”

When Senator Gaylord Nelson (D-Wisc.) founded Earth Day in 1970, his hope was to make the environment a political issue in an era where US rivers caught on fire and thick smog choked cities.

In many ways, it worked. Since then, major environmental laws have helped clean up much of the vivid toxic detritus in the soil, air, and water in the US. But our challenges today are no less daunting. The accumulation of greenhouse gases in the atmosphere, the loss of wilderness and species, and the acidification and pollution of the oceans have all become more acute — and more destabilizing.

In keeping with the tradition started by former Vox writers Brad Plumer and Joseph Stromberg, here are seven of the most troubling, intriguing, and encouraging things we learned about the Earth since the last Earth Day.

Biodiversity and Nature’s Contributions Continue Dangerous Decline, Scientists Warn

*Biodiversity and Nature’s Contributions Continue***

Dangerous Decline, Scientists Warn

Human well-being at risk. Landmark reports highlight options to protect and restore nature and its vital contributions to people

Biodiversity – the essential variety of life forms on Earth – continues to decline in every region of the world, significantly reducing nature’s capacity to contribute to people’s well-being. This alarming trend endangers economies, livelihoods, food security and the quality of life of people everywhere, according to four landmark science reports released today, written by more than 550 leading experts, from over 100 countries.

The result of three years of work, the four regional assessments of biodiversity and ecosystem services cover the Americas, Asia and the Pacific, Africa, as well as Europe and Central Asia – the entire planet except the poles and the open oceans. The assessment reports were approved by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES), in Medellín, Colombia, at the 6th session of its Plenary. IPBES has 129 State Members.

How Do Big Oil Companies Talk about Climate Science? Four Takeaways from a Day in Court

In front of a standing room only courtroom audience, the case of The People of California vs. B.P. P.L.C. et al. took an important step forward yesterday. In this case, the cities of San Francisco and Oakland, CA, are aiming to hold five major fossil fuel companies responsible for climate damages, particularly with respect to sea level rise. In a federal court in San Francisco, the presiding Judge William Alsup had specifically asked both sides to present a “tutorial on climate science” and to address eight questions he had posed. So how did the big oil company defendants present their version of climate science? And how did it compare to the scientific consensus? Together with my UCS colleague Deborah Moore, Western States Senior Campaign Manager, I was lucky enough to get a seat in the courtroom. Here are four of our takeaways from the day:

73% of Deep-Sea Fish Have Ingested Plastic

Microplastics can really be found everywhere, even in the stomachs of creatures living deep underwater.

Marine scientists from the National University of Ireland (NUI) in Galway found the plastic bits in 73 percent of 233 deep-sea fish collected from the Northwest Atlantic Ocean—one of the highest microplastic frequencies in fish ever recorded worldwide.

Timelapse video: shipping first as LNG tanker crosses Arctic in winter without icebreaker escort

Teekay vessel Eduard Toll is designed to cut through ice and take advantage of the opening of Russia’s Arctic coastline to industry.

An LNG tanker designed for icy conditions has become the first commercial ship to travel the Arctic’s northern sea route in winter.

It marks a milestone in the opening up of Russia’s northern coastline, as thawing polar ice makes industrial development and maritime trade increasingly viable.

The Teekay vessel Eduard Toll set out from South Korea in December for Sabetta terminal in northern Russia, cutting through ice 1.8m thick. Last month, it completed the route, delivering a load of liquefied natural gas (LNG) to Montoir, France. Its voyage was captured by the crew in a timelapse video.

What Does China’s ‘Ecological Civilization’ Mean for Humanity’s Future?

Imagine a newly elected president of the United States calling in his inaugural speech for an “ecological civilization” that ensures “harmony between human and nature.” Now imagine he goes on to declare that “we, as human beings, must respect nature, follow its ways, and protect it” and that his administration will “encourage simple, moderate, green, and low-carbon ways of life, and oppose extravagance and excessive consumption.” Dream on, you might say. Even in the more progressive Western European nations, it’s hard to find a political leader who would make such a stand.

And yet, the leader of the world’s second largest economy, Xi Jinping of China, made these statements and more in his address to the National Congress of the Communist Party in Beijing last October. He went on to specify in more detail his plans to “step up efforts to establish a legal and policy framework … that facilitates green, low-carbon, and circular development,” to “promote afforestation,” “strengthen wetland conservation and restoration” and “take tough steps to stop and punish all activities that damage the environment.” Closing his theme with a flourish, he proclaimed that “what we are doing today” is “to build an ecological civilization that will benefit generations to come.” Transcending parochial boundaries, he declared that his Party’s abiding mission was to “make new and greater contributions to mankind … for both the well-being of the Chinese people and human progress.”

‘Dangerous Drift-Prone Pesticide’ Threatens Millions of Acres, Hundreds of Endangered Species: Farmers and Conservationists Sue EPA, Monsanto

On Friday, public interest organizations representing farmers and conservationists made their legal case in a federal lawsuit against the U.S. Environmental Protection Agency (EPA) and the Monsanto Company, challenging EPA’s approval of Monsanto’s new “XtendiMax” pesticide. XtendiMax is Monsanto’s version of dicamba, an old and highly drift-prone weed-killer. EPA’s approval permitted XtendiMax to be sprayed for the first time on growing soybeans and cotton that Monsanto has genetically engineered (GE) to be resistant to dicamba.

The papers filed in court tell the story of how EPA should have known this would occur, yet instead was pressured by Monsanto into approving the pesticide without any measures to prevent vapor drift. The evidence in the case also shows that in late 2017, under pressure to take some action, EPA adopted revised instructions for use Monsanto proposed and approved—measures that agronomists believe will again be ineffective.

Trump administration could be sued over pesticide threat to orca and salmon

Fishing industry and environmentalists mull lawsuits
EPA tried to delay report detailing chemicals’ harm to wildlife

Commercial fishermen and environmental groups could file lawsuits against the Trump administration, if it fails to follow a recommendation by one of its own agencies to protect salmon, sturgeon, orca and other endangered species in the Pacific north-west.

The National Marine Fisheries Service (NMFS) recently issued a long-awaited opinion on three organophosphate pesticides – chlorpyrifos, diazinon and malathion.

It did so after a long court fight. Environmental groups sought publication of the opinion while the Trump administration, supported by pesticide manufacturers, pushed for a two-year delay.

The 3,700-page federal report was issued on 29 December. The scientists warned that the widely used pesticides pose a threat, through run-off into rivers and oceans, to dozens of endangered and threatened species.
