Olive Growers Adapt

Michael Antonopoulos, president of the Agricultural Cooperative of Kalamata, tells the Christian Science Monitor, “We want to adjust as soon as possible to the environment and be pioneers. Our place has to be fully ecological.”

In Greece, where farmers have grown olives for millennia, global warming has imposed a new normal. Nevertheless, writes Dominique Soguel at the Christian Science Monitor, “the result is not resignation. Rather, it’s fresh thinking and approaches.”

Soguel continues, “Olives and olive oil have become synonymous with Greece, and are credited, in part, with fueling the rise of Greek civilization. But despite a history spanning thousands of years, these culinary pillars of Greek identity are under threat. Small farmers expect this year’s harvest season, which got underway in November, to be one of the worst years on record, thanks to climate change and the irregular seasonal shifts it has wrought upon the flowering process and fruit development.

“ ‘We are collecting olives much earlier than ever before. Our producers do not recall any year like this,’ says Michael Antonopoulos, president of the Agricultural Cooperative of Kalamata. …

“He is not alone in expecting southern Europe to look like northern Africa in the span of 50 to 100 years. But Mr. Antonopoulos, a geologist and geotechnical environmentalist by training, is optimistic. He points to a series of steps that the community is taking to adapt to unseasonal temperature variations.

‘You can’t change the climate, but you can adjust.’

“[He] notes that traditional olive groves have an important role to play in combating climate change. They are carbon sinks and could easily be integrated into carbon-offsetting projects, increasingly popular but also controversial methods used to reduce the carbon footprint of a company or country. Kalamata is among six Greek cities participating in the European Union mission for 100 climate-neutral and smart cities by 2030.

“ ‘We want to adjust as soon as possible to the environment and be pioneers,’ he says. ‘Our place has to be fully ecological. We don’t care about higher productivity. We care about sustainability. We know people in the future will appreciate that more than anything.’

“One November day in Kalamata, as the mill that serves a community of roughly 300 olive oil producers operates at full throttle, the rain outside turns to hail. … It’s been that kind of year for Kalamata’s olive crop. In 2023, it endured winter conditions during the spring and, unlike much of Greece, experienced relatively low summer temperatures. That unusual weather, coupled with low rainfall, resulted in fewer and smaller olives. …

“ ‘If you don’t have certain weather conditions at a certain time,’ explains Mr. Antonopoulos, ‘you can’t have olive oil.’

“But the mill is also representative of how Greek olive farmers are adapting to the new environment. It is designed to run as sustainably as possible. Waste compost from the mill enriches the soil of the surrounding groves. It is the first mill in the region to rely on solar panel energy, and it recently secured a deal to sell electricity to the Greek government. Further, its farmers have adjusted their pruning tactics to optimize water use. And geothermal energy heats the olive oil extraction plants. …

“ ‘It’s all about feeding the soil,’ says George Kokkinos, head of the Nileas olive oil producers cooperative in the broader Messenia region, which encompasses Kalamata. ‘Soil health is top priority.’ …

“ ‘The philosophy was to look at how olive tree cultivation adapts to climate change,’ adds Mr. Kokkinos. ‘It was the first time that we heard of the expression “climate change.” … The consequences only start to be seen and felt here in 2016.’

“One of the most visible of these consequences, he says, are warmer, humid winters. This led to the spread of fungal diseases. Another change … summer now starts in July and lasts longer. All that confuses the olive tree, which decides in February whether to flower and delivers olives in April. …

“ ‘The normal, maximum temperature for this place this time of year would have been 16-18 C [60-66 F]. Typically, we would start the harvest wearing heavy clothes. Now we harvest in our T-shirts.’

“The mitigation measures are working, he says, even though recent summer heat waves dried up thesoil. He sees evidence of that in a 30% loss of productivity this year on his grove, compared with much higher losses among those who took no measures. The techniques they tested in the project now form part of the EU sustainable agricultural policy. But he worries that the Greek government is not prioritizing action and the spread of know-how to other farmers.

“ ‘The farmer stands in the middle and does not connect the dots,’ he says. ‘The average farmer in Greece is 60 years old. It’s a hard time. That’s true. But there are opportunities. The key is to adjust.’ ”

Revisiting Crocheted Coral Reefs

Posted in Uncategorized, tagged climate change, coral reef, craft, crochet, environment, marine, math on March 8, 2024| 2 Comments »

Coral Forest – Helsinki, crocheted from recycled plastic. A collaboration between Christine and Margaret Wertheim and the Helsinki Satellite Reefers, hosted by Helsink Art Museum and Helsinki Biennial 2021.

Remember my post on how crochet art was drawing attention to dying coral reefs? (See it here.) Well, after my friend Kristina told me about seeing some of the new additions to the crochet project, I decided to post a follow-up.

Siobhan Roberts reported at the New York Times in January, “Every year after the full moons in late October and November, Australia’s Great Barrier Reef begins its annual spawning — first the coral species inshore, where waters are warmer, then the offshore corals, the main event. Last year, this natural spectacle coincided with the woolly propagation of two new colonies of the Crochet Coral Reef, a long-running craft-science collaborative artwork now inhabiting the Schlossmuseum in Linz, Austria, and the Carnegie Museum of Art in Pittsburgh.

“To date, nearly 25,000 crocheters (‘reefers’) have created a worldwide archipelago of more than 50 reefs — both a paean to and a plea for these ecosystems, rainforests of the sea, which are threatened by climate change. The project also explores mathematical themes, since many living reef organisms biologically approximate the quirky curvature of hyperbolic geometry. …

“The surface of a sphere displays constant positive curvature; at all points, the surface bends inward toward itself. And a hyperbolic plane exhibits constant negative curvature; at all points, the surface curves away from itself. Reef life thrives on hyperbolism, so to speak; the curvy surface structure of coral maximizes nutrient intake, and nudibranchs propel through water with frilly flanges.

“In the artworks, marine morphologies are modeled — crocheted — with loopy verisimilitude. A bit like Monet’s water lilies, the crochet corals are abstract representations of nature, said Christine Wertheim, an artist and writer now retired from the California Institute of the Arts. Dr. Wertheim is the driving artistic force behind the project, which she created with Margaret Wertheim, her twin sister, a science writer who is in charge of scientific and mathematical components as well as management. …

“Crochet Coral Reef exhibitions typically have two main components: The Wertheims provide an anchor, of sorts, with works from their collection that they have crocheted over the years. They also incorporate pieces by select skilled international contributors. One is a ‘bleached reef,’ evoking corals stressed by increases in ocean temperature; another, a ‘coral forest’ made from yarn and plastic, laments the debris that pollutes reef systems.

“Then in response to an open call, volunteers far and wide crochet a pageant of individual specimens that agglomerate in a ‘satellite reef,’ staged by a local curatorial team with guidance from the Wertheims. … All contributors are credited.

“The largest satellite reef thus far coalesced in 2022 at the Museum Frieder Burda in Baden-Baden, Germany, with some 40,000 coral pieces by about 4,000 contributors. The Wertheims call this the Sistine Chapel of crochet reefs (documented in a splashy exhibition catalog). But the show at the Linz Schlossmuseum, which is dedicated to natural science as well as art and culture, is reminiscent of the work of the painter Giuseppe Arcimboldo, whose collage portraits from depictions of fruits, vegetables and flowers are ‘fantastically heterogeneous, also very funny and clever,’ Ms. Wertheim said.

“The Linz satellite reef unites some 30,000 pieces by 2,000 crocheters. The disparate parts take colorful inspiration from traditional Austrian ‘craftswomanship,’ as the exhibit text puts it, and there is a vast, glittery coral wall that gives a nod to the artist Gustav Klimt. In the Wertheims’ view, however, the crochet coral project is proof that it is not always lone geniuses who create great art, but also communities. In the art world, that is a radical idea, they noted, yet in science big collaborative projects and papers with thousands of authors are not unprecedented. …

“The mathematical dimension of the story intersects (from afar) with research by the applied mathematician Shankar Venkataramani and his students at the University of Arizona. They use idealized models to study hyperbolic surfaces in nature. [The] benefit, he said, is that it helps optimize processes like circulation and nutrient absorption. …

“When Margaret Wertheim, who studied math, physics and computer science at university, learned hyperbolic geometry, she found it ‘a bit bamboozling.’ She took the principles more on faith than understanding. Yet through crocheting models, she said, ‘you really do learn in a very deep way what a hyperbolic structure is, and in a way that I think is very powerfully pedagogical.’ “

See also Crochet Coral Reef, here. As the website notes, “Every crafter who contributes to the project is free to create new species of crochet reef organisms by changing the pattern of stitches or working with novel materials. Over time, a Darwinian landscape of wooly possibility has been brought into being. What started from simple seeds is now an ever-evolving, artifactual, hand-made ‘tree of life.’ “

A Cultural “Right to Be Cold”

Posted in Uncategorized, tagged arctic, climate change, global warming, ice, indigenous, Inuit on February 15, 2024| 8 Comments »

The Christian Science Monitor highlights indigenous “Guardians” who made a “hole in Arctic Ocean ice – a window on climate-related changes – where they monitor water quality and measure ice thickness.”

Cold parts of the world are threatened. The cold-loving people who live there are deeply concerned and are monitoring the losses for climate scientists.

Sara Miller Llana writes for the Christian Science Monitor, “Masked against the Arctic glare in orange-tinted sunglasses, Tad Tulurialik is a modern conservation ‘Guardian’ of his fast-melting homeland.

“At the start of an early summer workday that never sees the sun set, he kicks his all-terrain vehicle into gear. Safe in his ancestors’ knowledge of sea currents and ice fissures, he navigates a course right off the edge of the Canadian shore onto the aqua iridescence of the frozen Arctic Ocean. He’s following older Guardians to a manmade hole in the ice shelf, a window toward understanding climate-related changes in the sea.

“Even out on the ocean surface, his rifle is always swung over his shoulder. Wherever he sees a caribou or musk ox, it’s an existential given that he’ll take it. Food security isn’t found in a grocery aisle in this northernmost Canadian mainland settlement, tellingly named with the Inuktitut word for a caribou hunting blind.

“In some ways, as a government-paid conservation Guardian in training, the 24-year-old Mr. Tulurialik is doing what he’s done his whole life. Like most Inuit boys, he was ‘on the land’ as soon as he could walk. His childhood was spent on tundra and on sea and lake ice to hunt and fish with his grandparents, who raised him. His life was marked not by school grades but by first fox trapped, first polar bear shot. These were such priorities that he dropped out of high school.

“That could have made him part of Canada’s persistent social inequality – Indigenous youth in some of the remotest parts of the country, undereducated, underqualified, and often losing touch with rich traditions and fleeing homelands for economic opportunity. Except today, he’s part of a solution, as a member of Canada’s Indigenous Guardians, a conservation corps working in 170 far-flung Indigenous communities.

“Guided and taught by elders, he and other young Inuit born since 1989, when warming of the Arctic turned precipitous, are part of an effort to safeguard their homelands and their cultural ‘right to be cold.’ They’re also helping Canada achieve international conservation commitments made last year, when it led a global pledge at the United Nations Biodiversity Conference in Montreal to protect 30% of its land and oceans by 2030.

“For Mr. Tulurialik, who worked in construction and sewer maintenance after leaving school, a paid job as a conservationist is a dream: ‘I never thought I would work and get paid for what I grew up doing.’

“Together, he and his Guardian colleagues are tasked with creating a sustainable future, transforming Western-style conservation work into something that more closely resembles a traditional Indigenous environmental ethos. Guardians blend science with Indigenous knowledge in a budding conservation economy dependent on the transfer of knowledge from elders to youth.

“The ultimate aim of the Guardians’ work in Taloyoak is to use their sustainable Inuit practices – learned orally over millennia – to support the creation and maintenance of an Indigenous Protected and Conserved Area. The size of Maine, it is one of more than 90 in development across Indigenous Canada. Here in northern Nunavut territory, the IPCA conservation plan is led by the local hunter and trapper association.

It’s nurturing an economy of land-based jobs and markets as an alternative to a future in extractive industries in a territory long eyed by mining and oil interests.

“The land will be protected from development, conserving both biodiversity and a way of life based on sustainable hunting and fishing – while sequestering huge amounts of carbon, the culprit in global warming.

“ ‘This is a win-win situation’ … says Paul Okalik, the first premier of Nunavut who now works with Canada’s World Wildlife Fund (WWF), which is supporting Taloyoak’s efforts. …

“Indigenous lands, from the Brazilian Amazon to Hawaii coastlines to Canada’s high-latitude forests, represent 20% of the globe but hold 80% of the world’s biodiversity. Inhabitants have stewarded the land for centuries. Yet in a warming climate, their homelands are in some of the most at-risk environments.

“The Arctic is this nation’s – and arguably the world’s – crisis point. Here, warming is happening at up to four times the rate of the rest of the world, leading to melting permafrost, retreating glaciers, and receding sea ice. This has broad implications for the global ecosystem. Arctic ice melt slows ocean currents and makes the oceans more acidic – changes that have global implications for both climate patterns and sea habitats. Increased melting also creates what scientists call a ‘positive feedback loop’: As dark water replaces white snow on ice, the surfaces of the ocean and Earth absorb more sunlight rather than reflecting it. This causes even more warming. …

“Taloyoak locals have already worried about warming changing their ways. Last summer was the Northern Hemisphere’s hottest on record. The year prior, Taloyoak recorded its all-time hottest temperature of 78.8 F. Locals stayed home rather than go outside in, for them, the unbearable temperature.”

Imagine the high 70s being unbearable! The rest of North America will be learning about “unbearable” soon — if it hasn’t already.

Young African Fights Warming

Posted in Uncategorized, tagged africa, climate change, global warming, green, green hydrogen, namibia on January 12, 2024| 4 Comments »

Photo: Melanie Stetson Freeman/CSM Staff.
The Christian Science Monitor says, “Deon Shekuza is a peripatetic presence at climate summits as well as at the grassroots – like the class on green hydrogen he taught to young teens in an informal settlement in Windhoek, Namibia, last July.”

Climate activism is no longer mainly the purview of the industrialized Northern Hemisphere or those with enough income and time to worry about it. Now people on the front lines are leading the way. For them it’s a matter of survival.

Sara Miller Llana writes at the Christian Science Monitor about Deon Shekuza, a climate influencer in Namibia, who is “as comfortable proselytizing green energy to youth on the hardscrabble roads and villages of this former German colony as he is in Namibia’s government ministries and the halls of United Nations conferences.

“Paid with respect if not a salary, he’s part of a rising breed of young climate activists across the Global South whose work, suggests one climate expert, may well determine the temperature of your world.

“Africa, which has contributed least to climate warming, is the continent most threatened by the droughts, floods, and heat intensified by climate change. In that extremity, the relentlessly positive Mr. Shekuza sees great opportunity for progress for Namibia.

“In the dusty chaos of an informal settlement on the edge of this capital city one recent morning, he faces his biggest challenge: capturing the imaginations of young teens on a complex topic. The kids have gathered in a bright community center classroom, not for school credit and certainly not for fun on their Saturday off, but to hear Mr. Shekuza teach green hydrogen 101. Namibia has staked its future on this next big solution for a global clean energy transition. …

(The process, simply put, would use solar or wind power to extract hydrogen molecules from desalinated seawater, producing green ammonium that would be used for regional and global fuel markets to power transportation and electricity production.)

“No one here knows what green hydrogen is, let alone how it might be the route to social justice that Namibia’s leaders proclaim. Grasping for something understandable, Mr. Shekuza gestures out the window at the ancient and humble street scene of women laden with bushels of branches gathered from the forest for heating and cooking fuel. ‘This is exactly what we do not want for our people, right? Some energy sources keep you in the past, and some energy sources move you into the future. This is why we are here talking about green hydrogen.’

“After 90 minutes, Mr. Shekuza is satisfied. These kids might not exactly understand Namibia’s renewable energy policy, but they understand green hydrogen potential: jobs for them in a new economy that could turn Africa’s perpetual sunlight into clean fuel for electricity and transportation here and for export. …

“For activists across Namibia – like the Inuit in the Arctic, or youth from small island nations – caring and conserving is the easy part. These youth grew up living sustainable lives well before it was trendy. Many were born on the land, in the bush, on the coast, with no playgrounds except the natural environment around them. They conserved not for environmentalism, but for survival. …

“Mr. Shekuza and young African activists like him across the continent who are part of the Climate Generation, as we’re calling it, see a chance – the kind Mr. Shekuza tells the children in the informal settlement to seize, the kind he has seized for himself. …

“Mr. Shekuza can barely afford to do the work he has cut out for himself. For all his social confidence, he hesitates at the doorstep of his home before inviting visitors in for the first time ever. Descending from sunny daylight down a step at the side of a large old house, he enters the tiny basement space he shares with his mother.

“With a revealing flourish of humility, he pulls the worn blue curtain separating his mother’s bed from his floor space: ‘This,’ he says, ‘is climate activism in Africa.’

“In his windowless corner lies his bed. … On the chipped yellow paint of a cement wall are dozens of badges from U.N. conferences. A single business suit hangs from the curtain rope.

“This is the headquarters of his nongovernmental organization. With just the grants and fees he cobbles together from government and U.N. funding, the 33-year-old college dropout educates himself, hatches ideas for mentoring youth, and speaks via Zoom to august groups, all on the floor here. For an online speech on climate justice for a British Museum conference, he had no option but to give his speech right there, cross-legged on his sleeping pad, dressed in a traditional African tunic, surrounded by clothes, caps, shoes, and [policy] documents. …

“The environment, he says, was always a part of his interest: Nature was his escape from the noise and dilapidation of poverty in his rural hometown of Grootfontein. … ‘We are people who never look at the environment like something that is separate, because you grew up looking at it as part of you,’ he says. …

“He co-founded the NGO Namibian Youth on Renewable Energy (NAYoRE); gave himself the title ‘youth advocate for sustainable development’; worked with other organizations and networks on biodiversity, farming, and climate change; and started crisscrossing the globe on invitations to attend and address government, U.N., and private conferences. …

” ‘[Young people] may see me with a fancy English up here, but my lifestyle is no different from that kid in the shack. So when I speak for the youth, I’m coming from experience and I’m speaking something solid.’

“He pulls out a binder on agriculture in Namibia and how to use regenerative practices in one of the most water-stressed nations on the planet. It’s the latest document he’s read, and he’s read all of it: ‘I have dedicated hours and hours and hours … like trying to upgrade and up-skill myself. And I did that in and out of school, but I found the most benefit came out of it.’ …

“On a late Friday afternoon, Mr. Shekuza meets at a cafe with Micky Kaapama, whom he has been tutoring to be a climate activist, or, as they put it, a ‘biodiversity enthusiast.’ The glamorous fashion model studied biology and, crucially, has 12,000 Instagram followers. …

“As if trying to convince her of what she has to gain, he pulls out his phone to show an invitation from the Namibian president’s office that he’s just received. Addressed to Deon Shekuza, ‘Youth Advocate for Sustainable Development,’ it’s for a luncheon with Hyphen, a German- and British-financed Namibian company that signed a deal last May with Namibia to build the largest green hydrogen project in the country. It’s an $11 billion agreement.

“But there’s a hitch in the impressive invite. He has no idea how he can even afford to get to the event five hours away in Keetmanshoop.”

Mapping Underground Fungi

Posted in Uncategorized, tagged carbon, climate change, kazakh, mapping fungi, SPUN, steppe on January 3, 2024| 6 Comments »

Sometimes called a Fairy Circle, fungi like these tell a story of what is going on underground.

I don’t know as much about about fungi as New Zealand blogger Spores, Moulds, and Fungi — who posts some amazing photos from time to time — but in recent years, I have gotten interested in mushrooms and more.

Part of the reason is that I am noticing that they are beautiful. But also, as Jonathan Moens reports at the Washington Post, a few bags of dirt with the right fungi “could make the planet more resilient to climate change.”

Moens begins his story in Kazakhstan.

“A team of scientists loaded into a gray minivan [earlier] this year and drove for hundreds of miles west through the Kazakh steppe — a vast region marked by endless open plains of grass, abandoned farms and flower-filled meadows.

“It’s a desolate, semiarid landscape, but just a few inches below the ground may lie one of the most diverse fungi ecosystems on Earth.

“Across much of the planet, thin, wildly interconnected filamentous structures — known as ‘mycelium’ — hold the earth together. When these underground fungi come together, they form sophisticated systems known as ‘mycorrhizal networks.’ The Kazakh steppe, which stretches from the north of the Caspian Sea to the Altai Mountains, is one of the largest dry steppes in the world and is predicted to have a wild diversity of mycorrhizal fungi. But as the region becomes increasingly desert-like, many of these fungi may disappear.

” ‘There’s a time limit, 100 percent,’ said Justin Stewart, an evolutionary ecologist who led the mapping expedition. ‘If we collect a sample when it’s already a desert, then we’ve already lost all that diversity.’

“The Kazakhstan mission is part of a worldwide project led by the Society for the Protection of Underground Networks, or SPUN, a scientific research organization dedicated to mapping out underground fungi. The goal is to sample soil in 10,000 biodiversity hot spots across the world to create a global picture of what species of fungi exist and where.

“The team identified these areas using a predictive map based on thousands of observations and environmental data. In it, the Kazakh steppe stood out because of its wide-ranging diversity of ecosystems.

Understanding which mycorrhizal fungi survive in the harsh temperatures there may help scientists determine how these fungal communities might adapt to the climate crisis as droughts, fires and desertification become more prevalent.

“The researchers chose three areas of the steppe, each with a different climate: They began in the southern deserts, then drove out west to an area dominated by vast grasslands, agricultural lands and meadows. They ended north, near the Russian border, where they entered a forest ecosystem.

“At each site they took tens of samples by mapping out a grid with measuring tape, pounding a tube into the ground to extract the soil and storing this soil in a plastic bag for mixing. These samples may help scientists unlock secrets that could one day help ecosystems capture more carbon dioxide and restore soil health — as well as the trees, plants and animal life that rely on it. …

“Mycorrhizal fungi often form mutually beneficial relationships with plants. They trade essential nutrients such as phosphorus and nitrogen in exchange for carbon, and act as an extended root system, allowing plants to access water they can’t reach.

“These networks may also prove to be invaluable for transporting carbon underground, a study published in June found. About 13 gigatons of carbon fixed by vegetation — equivalent to about one-third of all carbon dioxide emissions from fossil fuels in one year — flows through underground fungi, according to an analysis of nearly 200 data sets.

“In the steppe, these plant-fungal benefits may be short-lived, however. While deserts are a natural part of Kazakhstan’s ecosystem, more than half of the country’s vegetation and drylands is at risk of becoming desert as well. The main drivers are large-scale intensive agriculture and increasingly warm and dry temperatures brought by climate change. …

“As the minivan moves northwest toward Kostanay, a city about 100 miles away from Russia’s southern border, the clay-red, barren landscapes give way to endless fields of grass. Herds of horses reared for meat consumption trot along the wide expanse while eagles circle the skies in search of prey.

“For hundreds of years, the steppe was a region of nomadic herders. In the 1950s, under Soviet rule, the government mobilized thousands of young volunteers to produce as much grain as possible in order to alleviate food shortages, an initiative known as the virgin lands campaign.

“The fields were extensively plowed, which degraded the soil, and were later abandoned because they were not productive. ‘It had an impact on vegetation, on steppe species — it’s now very fragmented in the northern part,’ said Alyona Koshkina, a researcher at the Association for the Conservation of Biodiversity of Kazakhstan, a national conservation group.

“The farming damaged the fungi networks, too, by ripping them out of the ground and stripping the soil of nutrients. The researchers hope the samples here give them more information on what kinds of fungi are able to survive in such unfavorable conditions, and compare it to other sites, such as forests and meadows.

“Over the years, the fields have had time to slowly recover, but they face new threats. Since 2021, the Kazakh government has been working on a nine-year project to bolster the livestock sector in the steppe.

“While grazing of the grasslands can help these ecosystems thrive, overgrazing may lead to further desertification, Koshkina said. To restore the steppe would mean winding back the clock to its pre-Soviet era, when the region was largely undisturbed or ‘pristine,’ she said. …

“Conservationists agree that the health of aboveground vegetation is inextricably linked to that of below-ground biodiversity. As such, mycorrhizal fungi may play an important role in shaping the steppe’s future. …

“Studying the steppe’s fungi could help scientists figure out whether they could thrive in other, similar climates. One way to test this would be via inoculation. If, for instance, SPUN’s work revealed that pristine steppes had higher mycorrhizal diversity compared with more degraded land, those same fungi could be transferred elsewhere to test whether they improve soil quality.”

More at the Post, here. A good person to follow at X, formerly known as Twitter, is Sam Knowlton, @samdknowlton, who works with fungi to improve soil health in agriculture.

See also the Guardian, here, where Fiona Harvey has more about mapping the world’s fungi. She quotes Jane Goodall, adviser to the SPUN project: “An understanding of underground fungal networks is essential to our efforts to protect the soil, on which life depends, before it is too late.”

Climate Confuses Haiku Poets

Posted in Uncategorized, tagged climate change, haiku, poet, season on January 1, 2024| 6 Comments »

Photo: Justin McCurry/The Guardian.
A path along the Sendaibori river in eastern Tokyo, Japan, that is dotted with tablets showing haiku by Matsuo Bashō, Japan’s most revered poet.

Happy New Year, Everyone! This year I want to do more things to reduce carbon emissions. Eat less beef? Compost more? Drive less? Turn down the heat and air conditioning? Some things are harder to do in community living, but I will find a way to influence group conservation.

Among the many areas threatened by climate change, there is one you probably never have thought about: the haiku!

Justin McCurry, writing at the Guardian, is not entirely joking.

“Wooden tablets dotted along a path between office buildings and the Sendaibori river in eastern Tokyo mark the start of a journey by Japan’s most revered poet that would result in his greatest collection of verse. The tablets showing haiku by Matsuo Bashō are steeped in the seasonal certainties of the late 1600s. There are references to full moons, chirping cicadas and, of course, cherry blossoms.

“Awareness of the seasons, and the seamless transition from one to the next, is found in myriad aspects of Japanese life [including] haiku poetry. Almost four centuries later, Bashō’s words continue to inspire admiration and countless amateur exponents of the 17-syllable form. But they are also a reminder that haiku faces what some of its enthusiasts fear is an existential threat: the climate crisis.

“The poems displayed at regular intervals along the Sendaibori promenade are intended to evoke the cooler climes of autumn, but this year they feel off kilter even though it is late September. …

“One of the poems encapsulates the feeling of seasonal misalignment.

“Ishiyama no
“Ishi yori shiroshi
“Aki no kaze

“A whiteness whiter
“than the stones of Stone Mountain
“The wind in autumn

“Bashō wrote those words after a visit to a hilltop temple in Komatsu, near the Japan Sea coast, on 18 September 1689. Read contemporaneously, they would have evoked the arrival of cooler, crisper days. … Today, though, they belong not just to another century, but to an age of symmetry between culture and the seasons that is being irrevocably blurred by the climate crisis.

“Japan is no stranger to extreme weather, but summers once described as uncomfortably muggy are now so hot that they represent a real threat to human life, especially among Japan’s large and growing population of older people. …

“The climate crisis is wreaking havoc on the Saijiki – the ‘year-time almanac’ of thousands of seasonal words that are widely acknowledged as acceptable for inclusion in haiku. A kigo could refer to a particular plant or animal, the weather, seasonal festivals, the sky and the heavens. When read at a corresponding time of the year, it is supposed to stir emotions in the reader.

“ ‘With kigo, you’re compressing three or four months into a single word,’ says David McMurray, a haiku poet who has curated the Asahi Shimbun newspaper’s Haikuist Network column since 1995. ‘Take the word mosquito … the entire summer is packed into that one word, and it conjures up so many images.’

“The premature first pops of sakura buds in spring and and the arrival of typhoons in the summer instead of the autumn are two notable examples of seasonal dissonance.

“ ‘The seasons are important to haiku because they focus on one particular element,’ adds McMurray, a professor of intercultural studies at the International University of Kagoshima. … ‘The risk is that we will lose the central role of the four seasons in composing haiku, and the Saijiki will essentially become a historical document. The Saijiki is very specific in the way it presents the words. But they no longer reflect reality.’ …

” ‘Take koharubiyori, a kigo of late autumn to early winter used to express a day of warm, mild, sunny, almost springlike weather in the midst of harshly cold days, associated with a sense of soothing and comfort,’ [Etsuya Hirose, a professional haiku poet] told the Nikkei business newspaper. ‘Nowadays, more days are warm at that time of year, so you can’t really empathize with that kigo, that season and emotion.’ …

“According to Toshio Kimura, a poet and director of the Haiku International Association, warmer, more unpredictable weather is blurring the transition from one season to the next, but haiku has the versatility to [adapt]. ‘The purpose of haiku is not to praise seasons themselves, but to try to see the human essence through nature.’ “

Growing Rice in Maryland

Posted in Uncategorized, tagged climate change, farmer, maryland, organic, rice, sustainable on December 6, 2023| 6 Comments »

Heinz Thomet stands in a field of sesame on his farm in Newburg, Maryland, Aug. 17. Mr. Thomet tries to grow nearly everything he eats.

I love the first line of today’s story about “one of only two commercial rice farmers in Maryland.” Because who knew there were rice farmers anywhere in the US? Don’t you think of rice farmers as being almost entirely in places like Japan and Vietnam?

Sophie Hills writes at the Christian Science Monitor, “Heinz Thomet is one of only two commercial rice farmers in Maryland. The other is Nazirahk Amen of Purple Mountain Organics. Not one to accept the status quo, Mr. Thomet grows six varieties of rice on his farm in southern Maryland, where most fields are planted with soybeans and corn. Mr. Thomet didn’t start growing rice until sometime during the past decade. His explanation for why he added the crop is simple: ‘I eat rice.’ …

He is the sort of person who has utter faith in natural processes but none in institutions.

“He’s always been a farmer, from growing up on a farm in Switzerland to working on a famed biodynamic farm in the United States as a young man. Since 2000, he’s farmed in Newburg, Maryland. There, in addition to the rice, he grows barley, Sichuan peppers, bananas, grapes, bitter lemons, oats, kiwis, sesame seeds, figs, and more, depending on the season.

“It’s difficult to make a profit on rice in Maryland. Farm-to-table was a natural concept for Mr. Thomet even before the movement expanded out of California in the early 2000s.

And though small-scale, direct-to-consumer farming is difficult to justify commercially, Mr. Thomet’s main concern remains the quality of the food he grows and stewardship of his land.

“In this case, that means successfully producing rice – a crop grown by few others on the East Coast. ‘Nothing of what I do makes sense for a cheap food system, but if you recognize a decentralized food system as food security, then I start to make sense,’ says Mr. Thomet. ‘If you look at diversified farms as part of the resilience towards a global weather pattern change, then I start to make change.’

“In an era of climate disruptions that are changing where everything from coffee and cacao to mustard and olives can be successfully grown, a decentralized food supply – like the one Mr. Thomet espouses – is getting a second look.

“After decades of factory farming and reliance on a global food chain that sends bananas, grapes, mangoes, and avocados thousands of miles to stores, returning to the idea that food should be grown where it is eaten is no easy task. And rice-growing is a useful case study.

“It’s unusual to find rice farmers anywhere on the East Coast, says Raghupathy Karthikeyan, Newman endowed chair of natural resources engineering at Clemson University in South Carolina. Rice production in the U.S. now takes place mainly on commercial farms in the Midwest and the South. But Mr. Thomet and fellow farmer Mr. Amen are holding on, despite the tight profit margin for small-scale, organic farmers.

“Both Mr. Thomet and Mr. Amen grow upland rice, a method that doesn’t use water for weed control, instead requiring labor-intensive weeding. While both sell their rice, neither grows enough to register on the U.S. Department of Agriculture census. Historically, Maryland farms mainly grew tobacco, and South Carolina was rice country. But the end of slavery and changing weather patterns made rice-farming less profitable. At one time, about 225,000 acres in South Carolina were planted with rice. Today, it’s somewhere between 25 and 50 acres. In Maryland, it’s 2.

“Agriculture in Maryland, as in most of the U.S., doesn’t supply much of the produce purchased in the state. Maryland farms produce more grain than other crops, and most of that is used for livestock feed and seed.

“Mr. Thomet’s interest is in locally grown crops for food, and he has a loyal base of customers, including restaurants.

“For Mr. Thomet, it’s not just about protecting the locavore movement. It’s also about stewardship. He quotes the motto of his family’s farm, Next Step Produce: ‘Committed to growing nourishing food in harmony with nature.’ …

“He eats what he grows and tries to grow whatever he wants to eat. In fact, Mr. Thomet has a nearly complete food system growing on the 30 acres he cultivates. The one thing he can’t grow is sugar cane, so he grows sweet sorghum instead, which is made into molasses.

“Day length, sun exposure, and night temperature in Maryland are all sufficient for rice to thrive, he says. Next Step Produce starts the rice in a greenhouse and then transplants it, allowing for more growing days so the farm can grow higher-yield varieties.

“Whether upland or lowland, rice is no longer profitable to grow in South Carolina – the historical center of U.S. rice-farming – unless it’s grown as a hobby, says Dr. Karthikeyan, who’s leading a study on climate-resilient rice production. The remaining commercial rice farms he’s aware of in the U.S. all grow lowland rice in paddy fields.

“Rice is a labor-intensive crop, even if you flood it, says Dr. Karthikeyan. The yield gap between upland and lowland rice is large, making it hard to turn a profit growing commercial varieties upland. That extra labor limits how many acres of rice Mr. Thomet plants, since they’re weeded by hand. It’s also reflected in the price, he says.

“Still, in his eyes, everything comes down to priorities and societal values. There’s no good reason everyone shouldn’t have access to nutritious, locally grown food, he says. Next Step Produce, which he runs with his wife and daughters, was certified organic for two decades until last year, when a red-tape snarl was the last straw for Mr. Thomet. But his customers don’t care about the label at this point, he says. They know his growing practices. …

“Benjamin Lambert, the executive chef at Modena, a restaurant in Washington, D.C., has bought from Mr. Thomet since 2007, when he met him at a local farmers market. ‘As a chef, you look for good ingredients,’ he says, standing in the restaurant, a James Beard Award hanging just behind him.”

What Is a Pawpaw?

Posted in Uncategorized, tagged climate change, indigenous, native american, pawpaw, root system on November 30, 2023| 3 Comments »

Pawpaw trees provide a rich tropical fruit, whose flavor has been compared to that of mangoes and bananas. Loved by Native Americans, pawpaws once fed people escaping slavery.

Recently the environmental radio show Living on Earth took a look at a fruit long beloved of indigenous people, the pawpaw, and asked whether it might be a good plant to introduce beyond its traditional range.

“STEVE CURWOOD: In many parts of North America, it’s well past harvest time, but not for the pawpaw. The pawpaw is a native fruit in the Eastern US that ripens in the late fall. Pawpaws were a delicious food source for Native Americans, as well for people escaping from slavery on the journey North to freedom. And there are still some pawpaw patches feeding folks today, though you can’t find them in grocery stores. Last spring When Living on Earth’s Bobby Bascomb spoke with Michael Weishan, former host of The Victory Garden on PBS, about gardening amid the coronavirus, Michael offered to dig up a few of his pawpaws for Bobby to try growing at home. …

“MICHAEL WEISHAN: Welcome to my pawpaw grove. So in front of us is the tree, It’s probably now about 30 feet tall and 15 feet wide. These are big, long lanceolate leaves [about] seven, eight inches long, three inches wide. And then as you go up, you see that they’re starting to change color. And that they’re a brilliant, brilliant yellow, which is one of the great fall features of this tree. …

“BOBBY BASCOMB: I’ve never seen one in the flesh, so to speak. [I] thought that they would be maybe bigger or greener or something.

“WEISHAN: It looks something like a green potato, wouldn’t you say?

“BASCOMB: Yeah, it’s a green potato. They’re sort of stuck together like a snow man or something. …

“WEISHAN: They’re not in commercial production because they’re very variable. So it would be very hard to ship them. They’re also, here you can feel one, they’re also quite soft.

“BASCOMB: Yeah, it’s like a ripe avocado. …

“WEISHAN: These trees are very unusual in that they form thickets … and they’re all tied via underground runners. And so when you try to go dig one up, you sever the runner. …

“BASCOMB: Now do they only reproduce by sending out runners? Or can you also take a seed and grow it and get a pawpaw? …

“WEISHAN: You can definitely plant the seeds. And presumably, that’s how this was grown. And that would actually be an easier way to propagate than these cuttings because then of course, it would form the roots within the pot. …

“The flowers are really interesting, too. They’re beautiful, long [inch] and a half flowers of a dark sort of vermilion purple color. And, interestingly, they have very little smell or a very unpleasant smell depending on your nose.

[They’re] propagated by flies, and not by bees. They bloom very early, before the bees are active. …

“BASCOMB: I was under under the impression that they grow really well in the south, like the Mid-Atlantic region and New England was sort of pushing the envelope for pawpaws. But yours looks pretty good here. …

“WEISHAN: We are at the northern edge of the range. So how much further north they will go? I don’t know. You’re right. They’re very well known down in the Mid-Atlantic and southeastern United States. However, with [climate change] things are moving north. …

“Plant it. If it dies, try the seeds. … I’m just gonna cut this open and then split it apart. [You] can see it’s like a banana. So at this point, I’m gonna give you a spoon. And these are the big black seeds. And you just take the seeds out, and then scoop it out like you would custard.

“BASCOMB: Hmm! It’s so good. Not what I expected. Everybody says banana and mango. And it’s got like, the texture of banana maybe, but …

“WEISHAN: It’s a delicious eating experience prized by the Native Americans. Of course, this was a principal food source all up and down the East Coast. A beautiful tree, great flower, great fruit … and great fall color. So if you can grow one of these in your yard, I highly recommend it.

“BASCOMB: [They] taste like a tropical fruit, almost, here in New England, which is so unusual. But … we’re into November and you’re just now harvesting these. That’s pretty unusual. [Even] apples are sort of on their way out at this point.”

Back from the Bronze Age

Melting glaciers are revealing older and older artifacts. Archaeologists discovered the arrow above in Norway’s Jotunheimen Mountains. Made out of freshwater pearl mussel, it’s one of the best preserved findings so far.

I hesitate to say that anything about climate change has an upside, but we might as well enjoy the things that keep being revealed — at least until we reach the more important goal of controlling global warming.

At Hyperallergic, Maya Pontone reports on melting glaciers in Norway and the latest Bronze Age discoveries.

“Archaeologists trekking through the Jotunheimen Mountains in Norway’s Innlandet County,” Pontone writes, “came across a remarkable find — an intact shell arrow dating back to the Early Bronze Age. Fastened with an arrowhead made of freshwater pearl mussel, the well-preserved hunting tool dates back 3,600 years and is one of eight shell arrows that have emerged from melting ice in Norway in recent years.

“On September 13, archaeologist Espen Finstad and his research team came across the artifact while checking a site as part of a routine monitoring job they typically run at the end of the field season. While the discovery of the ancient weapon was an unprecedented surprise that day, it is just one of hundreds that the Secrets of the Ice glacial archaeology team has uncovered over the past decade due to climate change.

“ ‘The glaciers and ice patches are retreating and releasing artifacts that have been frozen in time by the ice,’ Lars Holger Pilø, co-director of the archaeology program, told Hyperallergic. …

“The archaeologists have been continuously rescuing artifacts from Innlandet’s glaciers and ice patches since the fall of 2006, when the first ‘big melt‘ hit the Jotunheimen Mountains, located northwest of Oslo. [It’s the] home of the mythological jötnar, the rock and frost giants in Norse folklore. …

“ ‘Now the artifacts are exposed and deteriorating fast, so we are in a race against time to find and rescue the artifacts,’ Pilø said.

“So far, the Secrets of the Ice research team has mapped 66 ice sites and recovered approximately 4,000 finds including hunting gear and tools, textile remnants, transportation equipment, and clothing materials. The team has also found biological specimens such as antlers, bones, and dung.

“ ‘Arrows with shell arrowheads only became known in Europe when they started melting out of the ice in Norway,’ Pilø explained about the recent discovery. …

“As global warming transforms Norway’s mountainous landscape, Finstad, Pilø and their fellow glacier archaeologists are rushing to collect the exposed artifacts, which continue to get older as the ice continues to melt.

‘Most of the ice here in Norway will be gone in this century,’ Pilø said. ‘You can say that we are melting back in time.’

“Just last week, the team recovered another arrow, this one with an intact quartzite arrowhead, that is ‘probably 3000 to 3500 years old,’ according to Pilø. The team also found an iron horse bit with remnants of a leather bridle, a Medieval horseshoe, a Viking age knife, and an arrowhead for a crossbow bolt this month.

“ ‘The finds are incredible, but the reason they are melting out is sad,’ Pilø said, explaining how the ice melt will lead to drastic changes in Norway’s landscape, local wildlife, agriculture, tourism, and hydro-electrical power plants dependent on glacial water.

“ ‘It will be a very different world,’ he lamented.”

A Better Climate Curriculum

Posted in Uncategorized, tagged action, climate change, climate solutions, education, global warming, hope, positive on October 29, 2023| 3 Comments »

Unless people are committed to the “ain’t it awful?” worldview, they probably respond in more positive ways to pitches about hopeful progress than pitches describing how dire everything is.

In an opinion piece at Inside Higher Ed, Stephen Porder agrees, noting that climate-change education is more likely to be effective when students learn that there is hope.

Porder writes, “The first year I taught Introduction to Environmental Science was 2007, the year after the release of An Inconvenient Truth. The class was full of eager students, most of whom would have described themselves as environmentalists. … I was there to teach them the science — basically how to use hypothesis testing, data and analysis to convince them the world is going to hell. They didn’t need much convincing.

“The endless description of problems, with little emphasis on solutions, is a hallmark of almost all environmental science and studies textbooks. After 20-plus years teaching in this field, I’ve come to think that our relentless focusing on the negative is, at best, missing an opportunity. … My more recent experiences teaching about solutions, rather than problems, suggests that a healthy dose of positivity even in the face of profound environmental challenges will reach a broader audience, gain more traction and diversify the people working on the admittedly wicked environmental challenges of the 21st century.

“Back in 2007, I walked into the classroom, fresh out of my Ph.D. and postdoc, eager to share the wonders of environmental science. I marveled at the data from the group run by Charles Keeling, who measured rising carbon dioxide in the atmosphere at the observatory on Mauna Loa in Hawai‘i. … I dove into the details of carbon isotopes to demonstrate just how we knew that the rise in carbon dioxide was a result of fossil fuel combustion, as opposed to natural sources. The course was definitely a science course —but looking back I realize each bit of data and analysis was perfused with pessimism. …

“Still, my course evaluations were good. … These good evaluations came from students who were mostly self-selected environmentalists — passionate about ‘saving the planet.’ They were bright, motivated and talented. … Other equally bright, motivated and talented students didn’t take the course. I wondered why.

“Having talked to many such students since, I’ve learned many felt a bit excluded. The environment was a worry for them, as it is for most of us, but it wasn’t their primary worry. They also felt like environmental studies or sciences was not a place where they could explore solutions. They felt that there was a relentless focus on what was wrong, rather than how to put it right. Finally, they felt like the problems we were describing were going to be fixed by people beyond the environmental field.

“I’ve come to agree with them. I, at least, was not doing enough to train problem-solvers. I’d been training people to cleverly document problems. I don’t think I’m the only one in the field who’s fallen into that trap. …

“I handed off Introduction to Environmental Science to a younger professor a few years ago, and from here on out I’m focusing on solutions, not problems. Climate solutions. Agricultural solutions. Deforestation solutions. They exist. They are not perfect and involve hard trade-offs. But their existence should be front and center in our teaching.

“Just putting ‘Climate Solutions’ in a course name dramatically changed my student enrollment. Surprisingly, very few environmental studies and sciences students signed up. Instead, students majoring in economics, political science, engineering, applied math and a variety of humanities fields appeared in my classroom. … Like all my students, they were united by their climate anxiety. But they came for, and responded to, the idea of solutions.

“This eclectic group brought a wealth of different interests, skills and weaknesses to the class and was eager to learn from each other about different approaches to overcoming the 21st century’s biggest environmental (I would argue societal) challenge. They were thrilled at the opportunity to contribute to a better future, even if the environment was not their top priority (for some it became a top priority when they learned there were things they could actually do to make a difference). Many had felt unwelcome in environmental studies/sciences, which often demands a political and philosophical homogeneity of its participants.

“As an example of this, a senior applied math major told me he had been searching for a field where his math could have impact. He had never taken an environmental class before (despite plenty of environmental angst) in part because he didn’t feel welcome or like he fit in with environmentalists. He now works doing data analytics for a solar power company. …

“Solutions are picking up speed. Technological advances in transportation (electric vehicles), space heating (heat pumps) and electricity production (renewables) have made extraordinary leaps since I started teaching. Given that transportation, space heating and electricity generation make up more than 70 percent of all fossil fuel emissions, this is huge news! We should be teaching about it at every level and helping our students gain the skills to push these revolutions forward as engineers, community organizers, investors and so on.

“Already these advances have cooled our future. A decade ago, we were headed for four to five degrees Celsius warming by century’s end. Now three degrees Celsius is more likely. Anyone who studies climate knows that’s still way too much warming to be safe, but it’s also a huge step in the right direction. You may not hear that in most environmental science classes, or in the news, but you should. Even better news is that most of what precludes keeping that number to two degrees Celsius is political, not technological. That wasn’t true when I started teaching, so we need to update our curricula to reflect this remarkable progress.

“I don’t mean to be overly optimistic. The challenges to a stable climate future are enormous. … But by relentlessly beating a drum of negativity in the absence of hope, we’re driving away brilliant young minds that could help make the world a better place.”

Inuits Take Charge

Posted in Uncategorized, tagged canada, climate change, exploitation, indigenous, Inuit, nature, resource on October 14, 2023| 4 Comments »

Martin Shiwak, an Inuit, with his hunting rifle in his boat, on Lake Melville, near Rigolet in Nunatsiavut, Canada.

Can you handle another story about how we are finally learning that indigenous ways are better for everyone in a changing climate? I don’t mean we all need to hunt and fish. I’m talking about protecting land and water from resource exploitation.

Ossie Michelin writes at the Guardian that “the environment Inuit have lived in for millennia is changing fast. Canada’s government once ignored Indigenous knowledge of it but now they are jointly creating the Nunatsiavut conservation area. …

“Martin Shiwak accelerates his boat to grab the seal he has shot before the animal sinks out of sight. Shiwak has hunted for years in the waters of Lake Melville, by the Inuit community of Rigolet in Nunatsiavut.

“As he hauls the ringed seal into the vessel, he says he counts himself lucky to have found one so quickly. ‘Sometimes you have to drive around here in the boat nearly all day to find a seal,’ Shiwak says. ‘Nowadays you can’t even afford to – C$60 only gets you five gallons of gas.’

“Nunatsiavut – one of four Inuit homelands in Canada – is where the subarctic becomes the Arctic. An autonomous region of Labrador-Newfoundland province, it is located at the extreme north-east corner of North America.

“Winter temperatures here can average -30C (-22F) with the windchill, as the Labrador current brings Arctic ice floes down along the coast, and a host of marine life from, plankton to polar bears. From November to June, shipping is impossible because sea ice covers the entire 9,320-mile (15,000km) coastline, so all food and supplies must be flown in. In Rigolet, a frozen 1.5kg (3.3lb) chicken will set you back C$25 (£15). Hunting is not just a tradition but a necessity. …

“As a young boy, he learned to hunt and fish with his father and grandfather, who in turn had learned these vital skills from their elders. It is also how Shiwak learned the core Inuit values of taking only what is needed, sharing, sustainability and respect for nature – values he is passing down to his own children. …

“But while traditional knowledge has allowed Inuit to survive in this harsh environment for so long, the climatic conditions they rely on are changing quickly. Since 1950, Nunatsiavut has lost 40 days of ground snow a year. Its sea ice is vanishing faster than anywhere in the Canadian Arctic. …

“There is very little local people can do about that: although the region is roughly the size of the Republic of Ireland, Nunatsiavut’s population is less than 3,000, spread among five small towns. What they can do, however, is work to protect what they have. That’s why Nunatsiavut is partnering with the Canadian government to co-develop the world’s first Inuit Protected Area of this type.

“While there are other Inuit-led marine conservation programs in Canada, this will be the first to bear the title of Inuit Protected Area. … Built on Inuit values and culture, this type of conservation area would allow Indigenous people to continue traditional practices of hunting and fishing.

“That was not always the case. Past conservation policies saw Inuit at best only consulted and at worst completely ignored. Many Inuit hunters and fishers faced fines, had their equipment confiscated and their catches from hunting and fishing taken.

“Despite being granted the power to self-govern in 2005 (after 30 years of negotiations with the Canadian government), Nunatsiavut still lacked the final say over conservation in its waters. Final decisions defaulted to federal or provincial ministers.

“Now, at last, Nunatsiavut can jointly create and co-manage the protected area, based on Inuit priorities, as an equal authority. This will allow Inuit to practice traditional hunting and fishing in the area, while protecting the waters from industry and development.

“ ‘Just because we’re small doesn’t mean we can’t do something,’ says James Goudie, deputy minister of lands and natural resources in the Nunatsiavut government. ‘We can show the world that a small region can protect a massive amount of biodiversity.’

“The Inuit Protected Area would only cover about a third of Nunatsiavut’s nearly 50,000 sq km of offshore waters, but the region is home to important populations of fish such as salmon and Arctic char, the breeding grounds for many migratory birds, and the habitat of Arctic marine mammals including polar bears, beluga whales and seals.

“Establishing a protected area is also a pre-emptive strike against resource exploitation. Significant natural gas deposits have been found offshore along the Labrador shelf, but it has remained largely unexplored because of the ice. As the climate warms, however, the region is becoming more accessible – the Inuit Protected Area would prevent such resource exploration. …

“The borders of the new area have not been finalized, with the feasibility report expected in 2024 or 2025. But [Rodd Laing, Nunatsiavut’s environment director] notes: ‘You don’t need lines on a map to recognize the great work that happened already with Inuit relative to conservation and the management of ecological resources.’

“After all, he says, for countless generations of Inuit, conservation was not an option that could be ignored: it was a way to ensure there would be enough to eat, and enough next time as well.”

Mini Urban Forests

Posted in Uncategorized, tagged climate change, climax species, ecology, ecosystem, Miyawaki Method, urban forest on October 4, 2023| 6 Comments »

Illustration: Elara Tanguy.
The Miyawaki Method (bottom) speeds up the process of natural ecological succession (top) through the planting of “climax species.”

Ideas on combating climate change through the planting of sustainable forests come today from an employee-owned publishing company called Chelsea Green. Here they focus on a book by Hannah Lewis about the Miyawaki Method.

“Author Hannah Lewis is the forest maker transforming empty lots, backyards, and degraded land into mini-forests and restoring biodiversity in our cities and towns to save the planet. …

“Most of us know the term old-growth forest, which refers to natural forests that are still mostly free of human disturbance (though not necessarily free of human presence). These forests have reached maturity and beyond — a process that often takes centuries. As a result, they host incredible biodiversity and sustain a complex array of ecosystem functions.

“The Miyawaki Method is unique in that it re-creates the conditions for a mature natural forest to arise within decades rather than centuries.

At the heart of the method is the identification of a combination of native plant species best suited to the specific conditions at any given planting site.

“As we’ll see, determining this combination of special plants is not always so straightforward.

“More than just the species selection, the Miyawaki Method depends on a small collection of core techniques to ensure the success of each planting. These include improving the site’s soil quality and planting the trees densely to mimic a mature natural forest. It’s also necessary to lightly maintain the site over the first three years — which can include weeding and watering. Amazingly, though, if the simple guidelines are followed, after that point, a Miyawaki-style forest is self-sustaining.

“The trees grow quickly (as much as 3 ft per year), survive at very high rates (upward of 90 percent), and sequester carbon more readily than single-species plantations. The Miyawaki Method is also special for its emphasis on engaging entire communities in the process of dreaming up and planting a forest. Whether you are three years old or eighty-three, chances are you can place a knee-high seedling into a small hole in the ground. At the very least you can appreciate and cherish the return of quasi-wilderness to a space that was once vacant.

“The Miyawaki Method calls for planting native species, but not just any natives. In particular, the method involves a careful investigation of what’s known as potential natural vegetation (PNV). This unusual term refers to the hypothetical ecological potential of a piece of land. Or another way to say it is that potential natural vegetation is ‘the kind of natural vegetation that could become established if human impacts were completely removed from a site’ over an extended period of time. A site’s PNV depends on many factors, including current climate conditions, soil, and topography.

“How is potential natural vegetation different from the plants we see growing around us in towns and cities? For starters, in almost all developed landscapes, many of the plants are not native to the area, and as such may require maintenance to survive or reproduce.

“Given that most of Earth’s land surface is significantly altered by urbanization, agriculture, road construction, mining, and the like, it is far from obvious what the original vegetation of any given location would have been. (Original vegetation and potential natural vegetation are not necessarily exactly the same, but they are closely related.) Unraveling this mystery takes curiosity, patience, and persistence.

“However, thinking about land in terms of its potential natural vegetation is a powerful angle from which to approach ecosystem restoration, because it reveals which species and groups of species are best adapted to a particular environment and therefore more likely to thrive and to support a wider web of wildlife. …

“If left alone, previously forested land can grow back into mature forest via a process known as ecological succession, wherein the biological components of the ecosystem change over time as larger and longer-lived plant communities colonize the land. As mentioned, this process can take centuries to unfold. A foundational aspect of the Miyawaki Method is that it sidesteps the slow and capricious march of natural succession, instead focusing on those plants that mark the theoretical endpoint of succession.

“In nature, the successional process begins when lightweight seeds drift in and germinate on bare ground. Hardy, fast-growing plants — what scientists call pioneer species — such as clover, plantain, and dandelion take advantage of ample sunlight and space. They live short lives, produce a lot of seeds, and shelter the ground in the process. Next to show up are larger perennial herbs and grasses, followed by shrubs and pioneer trees, such as birch, poplar, or pine.

“ ‘Each new group of species arrives because the environmental conditions, especially the soil, have been improved; each new species becomes established because it is more shade tolerant than the previous species and can grow up under their existing foliage,’ Miyawaki wrote. He explains that just when a community of plants appears to be reaching its fullest potential, the seeds of the succeeding community are already germinating in its shade. The species making up each new successional stage tend to be bigger, more shade-tolerant, and longer living than those of the previous stage.

“ ‘The plant community and the physical environment continue to interact,’ Miyawaki explained, ‘until the final community most appropriate for the environment comes into being, one that cannot be replaced by other plant types. In regions with sufficient precipitation and soil, the final community is a forest.’

“Theoretically, this final community of plants, known as the climax community, is not easily superseded. Big trees that are considered climax species in their respective environments live for hundreds or thousands of years, forming canopies that shade the interior of the forest, keeping it cool and moist. Climax species shade out pioneer species and dominate the forest.

“ ‘In the absence of major environmental change, the climax is normally the strongest form of biological society and is stable in the sense that its dynamic changes are constrained within limits,’ Miyawaki wrote. Partly on account of the microclimate they create, such ecosystems tend to be more resistant to external conditions, such as heat or drought.”

Florida’s Ghost Reefs

Posted in Uncategorized, tagged bleaching, climate change, coral, florida, ghost reef, temperature on September 28, 2023| 9 Comments »

Severe bleaching and mortality in the Middle Florida Keys. Photo taken on July 24th.

One doesn’t always think of television news as going deep on a serious and complex problem, but I have to give credit to Florida’s WFLA for taking on dying ocean reefs. The sad tale makes me think we humans are like lobsters who don’t notice the water is boiling until it’s too late.

“Once colorful coral cities overflowing with marine life, transforming into ghost towns, or better stated, ‘Ghost reefs’ seemingly overnight.

“ ‘We are surprised by the pace. It is unprecedented what we have seen,’ said Scott Atwell the communications and outreach manager for the Florida Keys National Marine Sanctuary.

“Atwell told WFLA Chief Meteorologist and Climate Specialist Tuesday: ‘We’ve never seen anything like this. Some are not even bleaching, they are going straight to dead.’

“ ‘Straight to dead’ illustrates just how extreme the marine heatwave is and how quickly it’s evolving. When under stress, typically coral bleach first, expelling their symbiotic algae partners which give them their vibrant hues, and turn white. Then sometime later, if the heat persists, the coral can succumb and die.

“But right now in the Florida Keys, there are reports of rapid mortality. Coral is dropping like dominoes across much of the reef tract from Key Largo to Key West – the third largest tract in the world and the only shallow water reef system in the U.S. mainland.

“About 25% of marine life depends on coral reefs during some stage of their life. If coral reefs vanish it will have cascading consequences across ocean ecosystems and the life that it supports. …

“Mission: Iconic Reefs, a large-scale NOAA-led coral restoration initiative reports that the most recent seafloor temperature at Sombrero Key (off Marathon) is 93.4F and at Looe Key (off Big Pine Key) is 89.6F. According to Mission: Iconic Reefs the ‘optimal’ temperature for reef-building corals maxes out at 84 degrees.

“Although tropical corals live in warm water, they are very sensitive to just a couple of degrees Fahrenheit spike in sea surface temperatures, especially if it lasts for too long. NOAA Coral Reef Watch says at four weeks, coral can begin to show signs of stress. If the heat last eight weeks, a bleaching event becomes likely. [In July, we passed] the eight-week mark. …

“Bill Precht is a coral reef scientist in South Florida. In his 45 years studying coral, he’s never been so concerned about the Keys’ iconic reefs, ‘If things progress as they have started … the likelihood of catastrophic levels of mortality are high.’

“As a result of this unprecedented event, NOAA Mission: Iconic Reefs and their partner organizations are racing against the clock to rescue coral from the reefs and bring specimens into the lab where they can buy some time until the ocean cools back down.

“So the natural question is, when the coral die, can they recover? Dr. Katey Lesneski, the Coordinator of NOAA Mission: Iconic Reefs was asked that question by PBS News Hour and here’s what she said, ‘Once they die there are other reef organisms that will settle on that skeleton, take up space, and the coral tissue cannot grow back, unfortunately.’

“So the teams are taking drastic measures to gene bank two fragments from each unique genetic individual of staghorn and elkhorn corals, listed as threatened under the Endangered Species Act. In other words, they are preserving the genetic material so that if much of the coral is lost, there is a way to restore it.”

Today’s story is not only about addressing troubling effects of climate change in cities but also about encouraging young people in the communities most affected to be part of finding solutions.

Emily Piper-Vallillo reports at WBUR, “Boston students recently wrapped up a month-long study of extreme heat in Roxbury, exploring ways to mitigate the crisis and its impact on residents through the field of urban planning.

“Nearly 30 high school students participated in the University of Massachusetts Boston Summer Program in Urban Planning, which concluded [in July] with a presentation at Roxbury Community College. …

“The program introduces students of color from environmental justice communities like Roxbury and Dorchester to careers in urban planning and design. It’s part of a larger effort to diversify the field of urban planning, which remains overwhelmingly white.

“ ‘Only 5.2% of Boston’s planners are non-white, in a city where just in the city alone, 28% of our population is African American,’ said Ken Reardon, co-founder of the program and chair of UMass Boston’s Department of Urban Planning and Community Development. …

“Built as a working class community at a time when extreme heat was not as common as it is today, Roxbury has densely packed buildings with few trees, according to the students’ presentation. Many spaces are exposed to direct sun. Slides and swings in neighborhood playgrounds were constructed with heat-absorbing materials, making them unusable when temperatures rise.

“In fact, the students found that air temperatures in Roxbury are, on average, 10 degrees warmer than at Boston’s Logan Airport.

“They made this discovery by collecting 135 temperature readings across 38 Roxbury locations to identify the hottest spaces. Readings ranged from 83 to 102 degrees Fahrenheit, with the highest temperatures collected on sidewalks and at bus stops.

“Collecting data was grueling, said Blue Hills Regional Technical student Aidan Luciano. He and his peers hit the streets with remote sensors recording the humidity and heat index during the month of July — when temperatures sometimes rose above 100 degrees.

“ ‘[But] it’s going to pay off in the end because we are going to be helping other people,’ Luciano said. ,,,

“One group designed a new cooling children’s playground on RCC’s campus. Scheduled to open in 2025, the playground will replace a parking lot near the historic Dudley House site. After further community input, the final design will incorporate many ideas from the students themselves, said Ruben Flores, special projects manager at Roxbury Community College.

“Flores was particularly impressed by the inclusion of splash pads and water misters to reduce the temperature of the playground.

“Participating students received college credit from UMass Boston and were paid around $15 an hour.

“Paying students was an important part of making this opportunity accessible to low-income students of color who are less likely to be able to afford unpaid internships, Reardon said.

“Beyond collecting temperature data, students sought to understand how Roxbury residents experience extreme heat, said TechBoston student Neicka Mathias.

“Over the course of July, students interviewed nearly 100 Roxbury residents about coping with rising temperatures. The most common suggestion for improvement they heard was to increase the number of water sources throughout the neighborhood.

“Students also worked with residents to identify public spaces in Roxbury where heat mitigation solutions are most needed. These include areas where people frequently wait for public transit or line up outside favorite local restaurants. …

“ ‘Give a chance to these communities of color that are outside the spaces where decisions have been made and they will show you great work,’ Flores said.”

Flood Helps Art Treasure

The flooded banks of the Yamuna river near the Taj Mahal in Agra, India.

“It’s an ill wind that blows nobody good.” Maybe so, but how can severe flooding ever benefit a landmark?

First, let’s look at the worries about flooding near the Taj Mahal. In a July 20 Nikkei Asia report, Neeta Lal wrote, “Indians watched with alarm this week as the surging Yamuna River reached the outer walls of the country’s most recognizable landmark — the white-marbled Taj Mahal — for the first time in 45 years, due to heavy monsoon rains that have wreaked havoc and killed scores in the north of the country.

“Apart from highlighting the vulnerability of the 17th-century mausoleum in Agra, into which officials on Wednesday assured media the water was unlikely to enter, flooding has disrupted life across several states in recent weeks. Tens of thousands of people have been displaced, roads have caved in, homes have collapsed, and schools have been forced to close. Waist-deep water at Kaziranga National Park sent rare one-horned rhinos, elephants and deer fleeing to nearby villages, authorities said.

“A State Bank of India report this week made an early estimate of economic damage at nearly $2 billion.

“The crisis comes in a year when many parts of the world are experiencing severe heat waves and other extreme conditions attributed to climate change. Although flooding is nothing new in India, experts warn that global warming means the country can expect more extreme weather and must plan accordingly.

“New Delhi has not been spared. In the capital, nearly 10,000 people were forced into 33 makeshift relief camps arranged by the local Aam Admi Party (AAP) government, according to an official statement last week. Some were still in the shelters this week.

“Residents holed up at a camp in Delhi’s Civil Lines area complained of a lack of amenities. ‘We’ve been here for three days after losing all our belongings in floods but are struggling to get basics like food and water. Mosquitoes are also posing a problem,’ said Rashida Bai, 48, a widow and mother of three. However, her neighbor, Amina Yusuf, praised the government ‘for providing rations and promising 10,000 rupees ($122) per family as financial support.’ “

Meanwhile at Bloomberg CityLab, Sreeja Biswas addresses the Taj Mahal angle. “Extreme weather is a threat to cultural sites all over the world, but northern India’s latest monsoon may turn out to be positive for the Taj Mahal.from the Yamuna river, a major tributary of the Ganges, reached the compound walls of the UNESCO World Heritage Site on July 18, following a period of heavy rain that left thousands displaced in the neighboring state of New Delhi and caused devastating floods around the region. It was the closest Yamuna waters had come to the Taj Mahal in 45 years, flooding the visitor viewing area, according to local media reports.

“The Taj Mahal’s white marble exterior may suffer minimal damage, but the heightened water level will likely raise the moisture content of the structure’s wooden foundation, increasing its life span, said Raj Kumar Patel, superintendent archaeologist for the Archaeological Survey of India, a government agency responsible for archaeological research and preservation of historical monuments.

“The Taj Mahal is supported in part by a base of deodar wood, which becomes stronger when it absorbs water, Patel said. Drainage pipes divert the river water, and deep wells filled with rock, wood and other solid material provide stability to the massive building above.

“A drying Yamuna river has previously been a concern for the Taj Mahal — built in the 17th century by Mughal Emperor Shah Jahan in memory of his queen Mumtaz Mahal — as a lack of moisture shrank the supporting rafters at its base. The building has also suffered years of extreme air pollution and acid rain that has turned the monument yellow-green. …

“The recent flooding in northern India has been far less fortunate for other sites. The Mehtab Bagh, or Moonlight Garden, near the Taj Mahal, was mostly submerged in the recent rains and will likely need new grass, according to Patel.”
