From the lab to the field, agriculture seeks to adapt to a warming world By Jim Robbins on Jul 19, 2020

It may be coming to a bakery near you: bread made from wheat that has had its photosynthetic mechanism refashioned to help it flourish on a warmer planet. Despite the fact a number of researchers — some funded by the Bill and Melinda Gates Foundation — are scrambling to create this new breed of wheat, it won’t be arriving any time soon.

Increasing temperatures are already taking a toll on the world’s wheat fields. But a new heat-resistant wheat that will replace the types currently grown is a decade or more off in the future. The problem is being seen throughout the world. “It caused 30 percent reduction in national production, which is really huge,” said Senthold Asseng, a researcher at the University of Florida. Don’t have a cow, but Big Dairy’s climate footprint is as big as the UK’s. If dairy cows were a country, they would have the same climate impact as the entire United Kingdom.

Don’t have a cow, but Big Dairy’s climate footprint is as big as the UK’s

That’s according to a new analysis from the Institute for Agriculture and Trade Policy (IATP), which considered the combined annual emissions from the world’s 13 largest dairy operations in 2017, the most recent year for which data was available. The institute’s report follows up on a similar analysis the organization undertook for 2015. That year, the IATP found that the five largest meat and dairy companies combined had emissions portfolios greater than those of some of the world’s largest oil companies, like ExxonMobil and Shell. Dairy emissions come mostly from the cows themselves — specifically, from their notorious burps. Fermentation processes in cows’ stomachs produce the byproduct methane, which doesn’t stick around in the atmosphere as long as carbon dioxide but absorbs more heat.

Canadian farmers have a plan for tackling climate change

Agriculture is a major contributor to Canada’s greenhouse gas emissions. At the same time, farmers are hit by some of the worst effects of climate change. But a coalition of farming groups says they can also be a part of the solution. Climate change is making it harder to be a young farmer.

Climate change is making it harder to be a young farmer

With this season’s severe flooding, raging wildfires, and delayed planting, many of the country’s farmers are struggling to adjust as climate change sets in. Yet young and beginning farmers face unique challenges, farmers and advocates say, with tenuous finances, relatively small operations, and little government support to help them deal with the new, erratic normal. There are about 340,000 farms in the United States — 17 percent of the total — whose operators have been farming for less than 10 years, according to the Department of Agriculture’s Agricultural Resource Management Survey.

Waiter, there’s a climate surcharge in my soup

American restaurant diners don’t usually blink before adding an extra 15-20 percent tip onto their bills. In recent years, San Francisco’s eaters have even (mostly) grown accustomed to paying up to 6 percent extra for dinner to offset the cost of the city’s mandated healthcare program. Starting in January, at a smattering of eateries, California customers will see a new fee tacked on to their bill, though this one’s optional: One percent more to make their meal climate friendly. The surcharge will fund a new program called Restore California, which is managed by the nonprofit Zero Foodprint.

The initiative will funnel the money it raises into grants for farmers engaged in carbon farming — growing food with a focus on replenishing the soil’s health in order to increase the amount of carbon dioxide it can sequester.

People living in South Asia and Africa will bear the worst of it. Climate activists have been telling us for a while now that global warming isn’t just about the polar bears, so it’s hardly breaking news that humans are going to suffer because nature is suffering.

A hot planet threatens food and water more than realized, IPCC says

As the planet warms, parts of the world face new risks of food and water shortages, expanding deserts, and land degradation, warns a major new report from the United Nations’ Intergovernmental Panel on Climate Change. Those effects are already underway, and some of them could soon become irreversible. The changing climate has already likely contributed to drier climates in South and East Asia, North Africa, and the Middle East, reducing the food and water supply. In 2015, about 500 million people lived in dry areas that experienced desertification in recent decades as a result of human activities. Those problems are only going to get worse as climate change continues to take its toll. Last year, the same body issued the alarming finding that we have roughly a dozen years left before the world misses its window for averting runaway global warming.

Colombian coffee farmers are paying the price for climate change

At first glance, Finca El Ocaso, located in the hills outside Salento, Colombia, could be mistaken for a natural forest: Rows of squat Arabica coffee trees are interspersed with plantain, banana, and lime and shaded by towering nogal cafatero trees, whose high canopy hosts flocks of chattering parrots and other birds. The 44-acre coffee plantation has been certified by international organizations for being sustainable, climate-friendly, and fair to its workers. But Finca El Ocaso is struggling under the weight of intensifying economic pressures.

“Lots of smaller farms near us have gone out of business,” said farmer Gustavo Patiño. “It is no longer sustainable to have a medium-size farm that pays high taxes and expensive production costs, when in the end they may get paid less for their coffee than their expenses.” Others, however, are not so sure. Are pistachios the nut of the future? Inside a climate-controlled laboratory at the Duarte Nursery outside Modesto, California, an experiment is taking place that could help determine what food we will eat for decades to come.

Are pistachios the nut of the future?

Rows of steel racks contain numerous tiny almond, apple, walnut, pomegranate, pecan, avocado, fig, and pistachio trees in small translucent plastic cylinders. The saplings, planted in a high-nutrient agar mix that accelerates growth, are no more than 2 inches high and a few weeks old. Each is being subjected to versions of the stresses experienced just outside these walls in fields across the Central Valley: declining levels of water, escalating levels of salt. The big overarching, if unmentionable, force driving these experiments is climate change, which is beginning to roil the Central Valley. Duarte, one of the largest commercial nurseries in the world, specializes in tree nuts and fruits, which have boomed across the Valley in recent decades.

That’s the message sent by the International Fair Trade Movement to the parties gathering for the COP24.* The COP24 comes after the release of a number of reports on climate change.

The IPCC report on climate change this fall estimated that we collectively have 12 years to curtail emissions and stay below 1.5C of warming. Above that 1.5C, even a half a degree increase is tied to increasing floods, droughts, weather extremes, and poverty and displacement for millions of people around the world. Yet the report also finds that there are no physical, chemical, or technical hurdles to achieving that 1.5C goal. The obstacle is our collective will to make change. Agriculture is a big climate problem. Now farmers are sharing solutions. KATOWICE, POLAND — Hans Herren began his farm as a hobby almost 20 years ago. He’s been planting grapes and growing apple orchards on an 11-acre plot of land near Napa Valley in California. Thus far, the venture has been a success, but he knows he needs to make some adjustments soon.

“This year, I lost a lot of apples — the ones that were not inside the tree, covered by leaves so they were in the shade, were burned by the sun,” Herren said. He’s likely going to have to install a screen over his entire orchard to prevent fruit loss. Today, the average temperature in California is rising, and the nights don’t get as cool as they used to. While Herren’s farm sits roughly a mile out of the path of the state’s recent wildfires, he’s worried that the burned banks of the valley will lead to landslides, since the trees are no longer there to store water.

Yet while agriculture is suffering the impacts of a warming world, it is also a part of the problem. “This has to be done now,” Herren said.

COP24: Pour Aymeric Caron, il faut une agriculture «de plus en plus végétale» How farmers are turning to tradition as they face climate change. If ripened green beans aren’t picked, the whole bean plant begins to wither. In 2014, as a farm intern in Northern California’s Mendocino County, I went to harvest beans, despite the thick smoke from a fire 10 miles away. The farm couldn’t afford to lose the plants for the rest of the season; we needed to get the produce to the farmers market where the farm earned a third of its revenue. I wet a handkerchief and tied it around my nose and mouth, donned my hat and gloves, and began picking. S5 : Réchauffement climatique : la fin du chocolat ? Le 21 juin 2018.
