The phrase “necessity is the mother of invention” comes to mind when related to overcoming the obstacles of handling emergencies in remote or dangerous locations. But after listening to Zipline founder Keller Rinaudo’s TED talk, “entrepreneurship is the new philanthropy” seems more apropos. Our direct experience is more within the entrepreneurial conservation model in developing economies, but the energy with which many countries have leap frogged established technologies with 21st century models and solutions belies their assumed status of development.

Scientists Say They Have Found a Viable Replacement for Petroleum-Based Plastic
Scientists at Ohio State University say they have developed a viable alternative to petroleum-based plastic food packaging by using natural tree-based rubber. According to the researchers, the new biodegradable material holds promise for fighting the world’s growing plastic pollution problem, as well as for helping curb our reliance on fossil fuels.
The original source, with slightly more flowery language, titles it as if packaging can be friendly to the environment. The way we use packaging, not so. But we will take what we can get at this point:
New biodegradable ‘plastic’ is tough, flexible
The new bioplastic and rubber blend devised by Ohio State researchers proved much more durable than the bioplastic on its own
The quest to keep plastic out of landfills and simultaneously satisfy the needs of the food industry is filled with obstacles.
A biodegradable replacement for petroleum-based products has to meet all sorts of standards and, so far, attempts at viable replacements from renewable sources have faced limited success due to processing and economic constraints. Among the obstacles, products to date have been too brittle for food packaging. Continue reading
Mjösa Tower, the world’s tallest wooden building, under construction in Brumunddal, Norway. ANTI HAMAR
Thanks to Yale e360 and especially to Jim Robbins, as always, for keeping us up to date on the most interesting new developments in our natural world and its built spaces:
Mass timber construction is on the rise, with advocates saying it could revolutionize the building industry and be part of a climate change solution. But some are questioning whether the logging and manufacturing required to produce the new material outweigh any benefits.

The eight-story Carbon 12 building in Portland, Oregon is the tallest commercial structure in the United States to be built from something called mass timber.
If the many fervent boosters of this new construction material are right, however, it is only one of the first mass timber buildings among many, the beginning of a construction revolution. “The design community in Portland is enthralled with the material,” said Emily Dawson, an architect at Kaiser + Path, the locally-based firm that designed Carbon 12.
The move to mass timber is even farther along in Europe. That’s because mass timber – large structural panels, posts, and beams glued under pressure or nailed together in layers, with the wood’s grain stacked perpendicular for extra strength – is not only prized as an innovative building material, superior to concrete and steel in many ways, it is also hoped it will come into its own as a significant part of a climate change solution.

It’s been quite some time since we posted about biomimicry. Thanks as always to JoAnna Klein for this illuminating story:
“We think humans are the best designers, but this is not really true,” a researcher said.
In the capital of Zimbabwe, a building called Eastgate Centre holds nearly 350,000 square-feet of office space and shops. It uses 90 percent less energy than a similar sized building next door.
What’s Eastgate Centre’s secret? Termites.

In the 1990s, Mick Pearce, the building’s architect, took his inspiration from mounds built by fungus-farming termites he saw on a nature show. The insects created their own air conditioning systems that circulated hot and cool air between the mound and the outside.
As architects and builders seek new and improved ways to cool buildings without using more energy in a warming world, a study of another type of termite mound suggests that Mr. Pearce won’t be the last human to take design tips from these cockroach cousins. Continue reading
The greenhouse in Hinwil where Climeworks uses carbon dioxide pulled from the air to grow fruits and vegetables. Luca Locatelli for The New York Times
When this platform started in 2011 it was two young men, one a senior at Amherst College and the other a sophomore at Cornell University, who thought it would be useful to share their experiences with other students. It continued beyond their summer internships. At some point, hard to pinpoint the date, it started serving as a daily exercise for me. It became an exercise in finding something in the world that is worthy of attention, as much as possible something that inspires hope rather than reinforces dread (though that has been unavoidable from time to time).
The title I give to today’s post is impossible to justify with any metrics, but read on and you may see my point. Jon Gertner, for this first time featured in our pages, and for what is likely the longest of any longform treatments of any topic in the New York Times, thank you for making it about this:

Just over a century ago in Ludwigshafen, Germany, a scientist named Carl Bosch assembled a team of engineers to exploit a new technique in chemistry. A year earlier, another German chemist, Fritz Haber, hit upon a process to pull nitrogen (N) from the air and combine it with hydrogen (H) to produce tiny amounts of ammonia (NH₃). But Haber’s process was delicate, requiring the maintenance of high temperatures and high pressure. Bosch wanted to figure out how to adapt Haber’s discovery for commercial purposes — as we would say today, to “scale it up.” Anyone looking at the state of manufacturing in Europe around 1910, Bosch observed, could see that the task was daunting: The technology simply didn’t exist.
Over the next decade, however, Bosch and his team overcame a multitude of technological and metallurgical challenges. He chronicled them in his 1932 acceptance speech for the Nobel Prize for Chemistry — an honor he won because the Haber-Bosch process, as it came to be known, changed the world. His breakthrough made possible the production of ammonia on an industrial scale, providing the world with cheap and abundant fertilizer. The scientist and historian Vaclav Smil called Haber-Bosch “the most important technical invention of the 20th century.” Bosch had effectively removed the historical bounds on crop yields, so much so that he was widely credited with making “bread from air.” By some estimates, Bosch’s work made possible the lives of more than two billion human beings over the last 100 years.

The illustrative video above is on its own worth a couple minutes of your time. But the innovative approach to one of the world’s most pressing problems is the thing to take note of. Thanks to National Public Radio (USA) for bringing Evelyn Wang and Omar Yaghi’s work to our attention in this story:

Researchers have come up with a new way to extract water from thin air. Literally.
This isn’t the first technology that can turn water vapor in the atmosphere into liquid water that people can drink, but researchers from the Massachusetts Institute of Technology and the University of California, Berkeley, say their approach uses less power and works in drier environments.

I was not aware that Elizabeth Kolbert has been writing for Yale e360 for the entire time we have been linking to her New Yorker work on this platform. And then some, because she started publishing there ten years ago. This is her 17th publication for Yale e360 and it can help a layperson understand in a relatively short read whether technology has any chance of accelerating our progress on climate change mitigation:
A U.S. scientific panel reports that technologies that take CO2 out of the atmosphere could be a significant part of a strategy to mitigate global warming. In an e360 interview, Stephen Pacala, the panel’s chairman, discusses how these fast-developing technologies are becoming increasingly viable.
Is there still time to avoid runaway climate change? To a large degree, the answer depends on the feasibility of “negative emissions” — techniques or technologies that suck CO2 out of the air. In the latest report from the Intergovernmental Panel on Climate Change (IPCC), all scenarios for limiting warming to 1.5 degrees Celsius depend on negative emissions technologies, or NETs. Most 2-degree scenarios also rely on negative emissions; many call for removing billions of tons of CO2 per year by mid-century.
Negative Emissions Technologies (NETs) range from low-tech, such as planting more trees, to more high-tech options, such as developing machines to scrub CO2 from the air. NATIONAL ACADEMY OF SCIENCES, 2018
Yet most NETs remain either untested or unproved. To help bridge this gap, the National Academies convened a panel of scientists and asked it to propose a research agenda. The panel considered several possible techniques, ranging from the low-tech — planting more trees — to the high-tech — developing machines to scrub CO2 from the sky. It also looked at a hybrid technology that has become known as bioenergy with carbon capture and storage, or BECCS. The panel recommended several billion dollars be directed to research on NETs. Such technologies, it suggested, ought to be viewed as a “component of the mitigation portfolio,” rather than as a futuristic, last-ditch effort to reduce atmospheric CO2.

Stephen Pacala, a professor of ecology and evolutionary biology at Princeton University, chaired the panel. In an interview with Yale Environment 360, he talks about why NETs are needed, what should be done to advance them, and why he believes that “direct air capture” technologies could come into widespread use within the next decade.

Climate change has reared its big ugly head enough that I no longer count on seasonal consistency, but for now nine days in a row it has felt familiar, the greenest month of the green season in Costa Rica. And today, as of dawn, it looks like more of the same. “Some things never change” would be a real head in the sand cliché when thinking of seasons, but at least this October, so far, mornings have been sunny and by early afternoon the clouds roll in and the afternoons remind me of our 2010 to 2017 Kerala life, until dinner time. The photo above was from our second monsoon season there. Just up the hill from where I am writing at this moment, in Tarrazu–the Costa Rica equivalent of Munnar’s tea region–you might see something comparable, like this:
A few years ago Seth and James worked to restore a coffee plantation across the valley from the home where Seth grew up. The coffee they restored had been removed two decades earlier, a moment in time when coffee prices had crashed, even for the premium arabica that grows in Costa Rica. As it happens the same is true of the property where I am writing from, which had been a coffee plantation for most of the last century. In 2019 a restoration project will bring coffee back to this land, with tree shade for both the coffee and for the sake of restored bird habitat, and I look forward to sharing that progress here. And it is with this in mind that time, as an ingredient, is a theme for today. Work that Seth and James did demonstrated, with the passage of time, the fruitfulness of restoration and conservation. Now a replica project is ready to roll.
Time as an ingredient during green season is also a theme. Reading and cooking pass the time pleasantly during such afternoons, at least when the weekend schedule permits. Time for reading was on my mind a couple days ago, and the author featured in this podcast gets me thinking about time as an ingredient in the cooking I have been doing recently–almost all vegetarian and with the conscious effort to cook as minimally as possible to retain nutrients and flavor. As a bonus, this episode of a podcast we have been listening and linking to for two years shares the story behind espresso, so worth a listen:
A Los Angeles distillery aims to speed up a 10-year aging process to a matter of days.
Why does fish cook so fast? What’s the “wasabi window”? And can you really make 20-year-old aged whiskey in six days? This episode, we’re looking at the role of time in food and flavor: what it does and how we’ve tried—and sometimes succeeded—to manipulate that. To explore these questions, we visit a whiskey time machine tucked away in a low-slung warehouse in downtown Los Angeles and meet its inventor, Bryan Davis. And we speak with Jenny Linford, a food writer and author of a new book, The Missing Ingredient, all about time and food. Listen in now—this one’s well worth your time! Continue reading

Thanks to Matthew Taylor and colleagues at the Guardian for this news:
Thanks to Redhouse Studio and the Guardian’s Laura Dorwart for this story:
You can click on any of these photos to go to their source, and they are inserted here because the article that brought this farm (?), this company, this phenomenon to my attention did not have any images. It was good to have only the New Yorker words to start with because, like all good writing, it forced me to imagine what this might look like. However, my imagination fell short.
Farm.One is New York City’s grower of rare herbs, edible flowers and microgreens for some of the best restaurants in the city. Our Edible Bar and Tasting Plates make these fresh, exciting ingredients available for the first time in an event setting. Guests can discover botanical ingredients for the first time, with the expert guidance of our farm team. Taste ingredients on their own, or paired with cocktails and other beverages, for a colorful, flavorful and aromatic experience like no other.
This short piece by Anna Russell below continues our stream of thought about the farm of the future, and takes it into very unexpected territory. Hydroponics and urban farming have been featured many times in these pages over the years so that is not what has our attention. It is the mixing of art and agriculture that gets us thinking outside the box:
Chic stems and tender greens thrive deep below Worth Street on the rolling shelves of Farm.One.
Hydroponics are a slippery slope. You might find yourself, one Sunday morning, at a Santa Monica farmers’ market, loitering among the apples, say. You come across a bunch of papalo, a leafy herb native to central Mexico, and toss it in your mouth (your tastes are expansive; a papalo leaf is nothing to you) and wham!: a brand-new flavor. Suddenly, you’re up at all hours, watching vertical-farming videos on YouTube, ordering seed packets from eBay, buying rhizomes—rhizomes!—and worrying about spider mites. You get some fennel crowns and a pouch of parasitic wasps, and you’re on your way. Continue reading
Thanks to our friends at the salt, and National Public Radio (USA) for this:
If you’re interested in sustainability, you’ve probably thought about how to reduce your carbon footprint, from how you fuel your car to how you heat your home. But what about carbon emissions from growing the food you eat?
Most of the crops in the United States are grown using chemical fertilizer – a lot of it: American farmers used over 24 billion pounds of nitrogen fertilizer in 2011. And making nitrogen fertilizer requires fossil fuels like natural gas or coal. Continue reading

Our attention has been on food entrepreneurship recently, and here we continue the thread. With agroecology, a new word and robust concept, we have new food for thought. And for that we thank one of our favorite food writers, who we have relied since the first year of this platform. Many of the food stories we have linked to over the years have been authored by him. A year ago we linked to this story, which marked the first time we noted him as an activist. We expect, after reading Bringing Farming Back to Nature, which he co-authored with Daniel Moss, that he has found his new calling:

Farming the land as if nature doesn’t matter has been the model for much of the Western world’s food production system for at least the past 75 years. The results haven’t been pretty: depleted soil, chemically fouled waters, true family farms all but eliminated, a worsening of public health and more. But an approach that combines innovation and tradition has emerged, one that could transform the way we grow food. It’s called agroecology, and it places ecological science at the center of agriculture. It’s a scrappy movement that’s taking off globally. Continue reading
Prototype wind turbines whirl at a testing site in Osterild, near the northern end of Denmark’s Jutland peninsula. By Rasmus Degnbol
Thanks to the New York Times for this reminder that, in spite of what headlines often lead us to believe, progress is out there on as many fronts as we care to look to:
Blades for wind turbines lie outside a factory, waiting to be transported to wind farms.By Rasmus Degnbol
OSTERILD, Denmark — At the northern end of Denmark’s Jutland peninsula, the wind blows so hard that rows of trees grow in one direction, like gnarled flags.
Technicians reach the roof of these enormous wind turbines either via an internal elevator or, if the turbine is installed offshore, by helicopters that lower them into the fenced-off area.By Rasmus Degnbol
The relentless weather over this long strip of farmland, bogs and mud flats — and the real-world laboratory it provides — has given the country a leading role in transforming wind power into a viable source of clean energy.
After energy prices spiked during the 1973 oil crisis, entrepreneurs began building small turbines to sell here. “It started out as an interest in providing power for my parents’ farm,” said Henrik Stiesdal, who designed and built early prototypes with a blacksmith partner. Continue reading

Thank you Andrea DenHoed. We did not know how much we should appreciate them:
In 1907, just a few years after the Wright brothers lifted off in Kitty Hawk, and while human flight was still being measured in metres and minutes, Dr. Julius Neubronner, a German apothecary, submitted a patent application for a new invention: the pigeon camera. The device was precisely what it sounds like—a small camera fitted with straps and equipped with a timer so that pigeons could carry it and take photos in flight. Neubronner first used the device on his own flock of homing pigeons, which he sometimes employed to deliver prescriptions. In the following years, he showed his camera at international expositions, where he also sold postcards taken by the birds. Additionally, he developed a portable, horse-drawn dovecote, with a darkroom attached to it, which could be moved into proximity of whatever object or area the photographer hoped to capture from on high.

Derek Thompson, writing in the Atlantic recently, has a very readable consideration of the fashionable obsession with disruptors, a topic we give too little attention to in these pages. So, a small step forward:
Tech analysts are prone to predicting utopia or dystopia. They’re worse at imagining the side effects of a firm’s success.
The U.S economy is in the midst of a wrenching technological transformation that is fundamentally changing the way people sleep, work, eat, shop, love, read, and interact.
At least, that’s one interpretation. Continue reading

Among contributors to this platform, the number of lego pieces bought over the last fifty years likely aggregates into the hundreds of thousands. And yes, we all eventually knew that the product is petroleum-based and therefore worthy of reconsideration in for the next generation. But they have remained irresistible anyhow, and so we are glad to hear the company is moving in a new direction. Rebecca Smithers, the Consumer affairs correspondent for the Guardian, offers this news on where the company is going with green:
