In some cities, as many as one in four office spaces are vacant. Some start-ups are giving them a second life – as indoor farms growing crops as varied as kale, cucumber and herbs. In countries including Canada and Australia, landlords are struggling to fill vacant office spaces as companies embrace remote and hybrid work. In the US, the office vacancy rate is more than 20%. "Vertical farms may prove to be a cost-effective way to fill in vacant office buildings," says Warren Seay, Jr ... who authored an article on urban farm reconversions. There are other reasons for the interest in urban farms, too. Though supply chains have largely recovered post-Covid-19, other global shocks, including climate change, geopolitical turmoil and farmers' strikes, mean that they continue to be vulnerable – driving more cities to look for local food production options. Workers are currently aiming to transform a floor of 32-story historic Niels Esperson building in Houston, Texas, into an indoor farm. In September 2024, US indoor farm startup 80 Acres, which opened its first indoor farm inside a vacant building in Hamilton, Ohio, developed a 200,000-sq-ft (18,600-sq-m) facility inside a former commercial building in Florence, Kentucky. Overall, vertical farms have the potential to outperform regular farms on several environmental sustainability metrics like water usage, says [director of the Arell Food Institute] Evan Fraser.

Water hyacinths are native to South America, but were introduced as an exotic ornamental to many other countries. They’ve since taken over freshwater environments and are labeled an alien invasive species on every other continent aside from Antarctica. As well as their impact on biodiversity and livelihoods, the floating plant can clog hydroelectric and irrigation systems, meaning that one does not need to live in their proximity to be affected. It’s the highest-profile example of an invasive aquatic plant crisis that has cost the global economy tens of billions of dollars historically, and now more than $700 million annually. Now a Kenyan company is addressing the problem as well as the country’s plastic pollution issue by turning the invasive plant into a bioplastic. HyaPak Ecotech Limited, founded by Joseph Nguthiru, began life as a final year project by the former Egerton University civil and environmental engineering student. Nguthiru’s bioplastic is made from dried water hyacinth combined with binders and additives, which is then mixed and shaped. The product, which biodegrades over a few months, was first used as an alternative for plastic packaging. HyaPak has gained widespread attention, winning the Youth category at the East Africa Climate Action Awards, a prize at UNESCO’s World Engineering Day Hackathon, and a Prototype for Humanity Award 2023 announced at the COP28 climate conference.

An eco-friendly fitness trend that started in 2016 is now growing in popularity with its own world championship competition in Italy. Originating in Sweden, when Erik Ahlström began picking up litter while jogging in Stockholm, the term is a combination of the Swedish word plocka, which means “to pick up”, and the English word “jogging”. The activity of picking up litter while on your outdoor jog, has spread to other countries, and now an estimated 2 million people ‘plog’ regularly in over 100 countries. The workout adds bending, squatting, and stretching to the main action of running—with ‘pliking’ being the latest offshoot for hikers who want to clean up the trail. The third annual World Plogging Championship in 2023, resulted in approximately 6,600 pounds of litter (3,000 kg) removed from the environment around the city of Genoa. Later this year, a British team will be traveling to the competition with the goal of running the farthest and picking up the most rubbish. Claire Petrie recently kick-started her training with community events in her hometown of Bristol. “I love that you help the environment, the planet and meet new people,” said the 48-year-old personal trainer who became passionate about combining health and the environment. “We want to grow plogging in as many cities as possible.” During the past year, Claire’s group, which plans to expand into other areas in Bristol but currently has an average of 9 people joining in, collected 220 pounds of trash (100 kg).

Lee Tesdell walks through a corridor of native prairie grasses and wildflowers. This is a prairie strip. Ranging from 10-40 metres (30-120ft) in width, these bands of native perennials are placed strategically in a row-crop field, often in areas with low yields and high runoff. Tesdell has three on his farm. He points out several native plants – big bluestem, wild quinine, milkweed, common evening primrose – that came from a 70-species seed mix he planted here six years ago. These prairie plants help improve the soil while also protecting his more fertile fields from bursts of heavy rain and severe storms. Research shows that converting as little as 10% of a corn or soya bean field into a prairie strip can reduce soil erosion by 95%. Prairie strips also help reduce nutrient pollution, store excess carbon underground and provide critical habitat for pollinators and grassland birds. Thanks to federal funding through the USDA’s conservation reserve programme, they’ve taken off in recent years. Farmer Eric Hoien says he first heard about the conservation practice a decade ago, right around the time he was becoming more concerned about water issues in Iowa. Hoien says prairie strips offer other benefits close to home. Neighbours often tell him they appreciate the wildflowers and hearing the “cackle” of pheasants. He also enjoys hunting in the prairie strips and spotting insects he’s never seen before. The strips are hugely beneficial for pollinator populations.

Juan Guillermo Garcés remembers coming face to face with death at age 17. Garcés and his brother started the fire that nearly killed them to clear a large stretch of land. The brothers survived, but the fire destroyed the little remaining patch of virgin forest on the family’s 2,500-hectare (6,200-acre) ranch, nestled along Colombia’s Magdalena River. In an attempt to undo the damage he caused in his youth, the 74-year-old created the Rio Claro nature reserve, a 3,000-hectare (7,400-acre) oasis teeming with wildlife. Today, Garcés’s reserve marks him as one of Colombia’s most successful environmental protectors. The Rio Claro basin is home to almost 850 species of fauna and more than 3,000 of flora. “More than 100 new species have been discovered in Rio Claro … and counting,” says Saúl E Hoyos-Gómez, a botanical biologist. “It is a very special place – one of the few where you can find this level of biodiversity.” His method is simple. He buys plots of land from peasant farmers, often deforested pastures, and then lets them rest. Recovery in the region’s hot and humid climate is fast. Left alone, pasture reverts to jungle within decades. About 80% of Garcés’ reserve consists of land reforested in this way. To build his reserve, Garcés has had to navigate complex relationships with peasant farmers, the government and armed groups. Growing numbers of Colombian landowners are following Garcés’s lead, turning pastures into reserves.

When Marco de Kat starts planning his meals, he doesn’t need to travel far for fresh food. Right outside his house is an 800 square metre plot with all sorts of produce – apples, pears, peppers, basil, beets and cauliflower, to name a few. Oosterwold, where de Kat has lived since 2017, is a 4,300 hectare (10,625 acre) urban experiment located east of Amsterdam, in a suburb of the city of Almere, where de Kat works as a municipal councillor. The area, which has about 5,000 residents and a growing waiting list, is completely self-sufficient. Residents can build houses however they like, and must collaborate with others to figure out things such as street names, waste management, roads, and even schools. But the local government has included one extremely unusual requirement: about half of each plot must be devoted to urban agriculture. Some, like de Kat, have turned their gardens into an Eden of sorts to provide for their own household unit. Other residents just plant a few apple trees or outsource by owning plots of land on site that are tended to by professional farmers. Others, such as Jalil Bekkour, have been able to capitalise on it. “I never had experience gardening my own food or anything like that,” he said. But he taught himself how to garden, and three years ago he opened his own restaurant, Atelier Feddan, where 80% of the food is directly from Oosterwold. His newfound excitement for gardening and agriculture is palpable.

When large swathes of invasive seaweed started washing up on Caribbean beaches in 2011, local residents were perplexed. Soon, mounds of unsightly sargassum – carried by currents from the Sargasso Sea and linked to climate change – were carpeting the region’s prized coastlines, repelling holidaymakers with the pungent stench emitted as it rots. Now, a pioneering group of Caribbean scientists and environmentalists hope to turn the tide on the problem by transforming the troublesome algae into a lucrative biofuel. They recently launched one of the world’s first vehicles powered by bio-compressed natural gas. The innovative fuel source created at the University of the West Indies (UWI) in Barbados also uses wastewater from local rum distilleries, and dung from the island’s indigenous blackbelly sheep which provides the vital anaerobic bacteria. The team says any car can be converted to run on the gas via a simple and affordable four-hour installation process, using an easily available kit, at a total cost of around $2,500 (£1,940). “Tourism has suffered a lot from the seaweed; hotels have been spending millions on tackling it. It’s caused a crisis,” Dr Henry, a renewable energy expert and UWI lecturer, [said]. The idea that it could have a valuable purpose was suggested by one of her students, Brittney McKenzie, who had observed the volume of trucks being deployed to transport sargassum from Barbados’ beaches.

Left on their own, some deforested areas can rebound surprisingly fast with minimal help from humans, sequestering loads of atmospheric carbon as they grow. New research from an international team of scientists, recently published in the journal Nature, finds that 830,000 square miles of deforested land in humid tropical regions—an area larger than Mexico—could regrow naturally if left on its own. Five countries—Brazil, China, Colombia, Indonesia, and Mexico—account for 52 percent of the estimated potential regrowth. That would boost biodiversity, improve water quality and availability, and suck up 23.4 gigatons of carbon over the next three decades. “A rainforest can spring up in one to three years,” said Matthew Fagan, a conservation scientist and ... coauthor of the paper. “In five years, you can have a completely closed canopy that’s 20 feet high. I have walked in rainforests 80 feet high that are 10 to 15 years old. It just blows your mind.” That sort of regrowth isn’t a given, though. First of all, humans would have to stop using the land for intensive agriculture—think big yields thanks to fertilizers and other chemicals—or raising hoards of cattle, the sheer weight of which compacts the soil and makes it hard for new plants to take root. A global goal known as the Bonn Challenge aims to restore 1.3 million square miles of degraded and deforested land by 2030. More than 70 governments and organizations from 60 countries ... have signed on.

Tangles of grapes and blackberries grow in clusters along a trellis. Leafy rows of basil, sweet potatoes and mesclun spring from raised garden troughs. Most striking are corridors of elevated planters stacked four high, like multilevel bunk beds, filled with kale, cabbage, arugula, various lettuces, eggplants, tatsoi and collard greens. Run by a gardening wizard named Jamiah Hargins, this wee farm in the front yard of his bungalow provides fresh produce for 45 nearby families, all while using a tiny fraction of the water required by a lawn. At just 2,500 square feet, this farm forms the heart of Mr. Hargins’s nonprofit, Crop Swap LA, which transforms yards and unused spaces into microfarms. It runs three front yard farms that provide organic fruits and vegetables each week to 80 families, all living in a one-mile radius, and often with food insecurity. Rooted in the empowering idea that people can grow their own food, Crop Swap LA has caught on, with a wait list of 300 residents wanting to convert their yards into microfarms. The mini farms bring environmental benefits, thanks to irrigation and containment systems that capture and recycle rain. That allows the farms to produce thousands of pounds of food without using much water. “Some people pay $100 a month on their water because they’re watering grass, but they don’t get to eat anything, no one gets any benefit from it,” Mr. Hargins said. “I can’t think of a more generous gift to give to the community than to grow delicious, naturally organic food for the direct community,” [says Crop Swap LA subscriber] Katherine Wong. “This is one of the noblest things anyone is doing today.”

The explosion of the No. 4 reactor of the Chernobyl Nuclear Power Plant near Pripyat, Ukraine on April 26, 1986 remains the worst nuclear disaster in human history. It left a 30-kilometer exclusion zone—a deserted landscape where high radiation levels remain even now, decades after the incident—where human settlement and habitation are restricted. Within this zone, however, scientists have discovered an unlikely survivor: a resilient black fungus called Cladosporium sphaerospermum. After the Chernobyl disaster, scientists observed patches of blackened growths on the walls of the No. 4 reactor—fungi that seemed to thrive where the radiation was highest. This fungus has adapted to a level of radiation that would be lethal for most life forms. Even more fascinating is its ability to “feed” on this radiation, using it as a source of energy, similar to how plants use sunlight for photosynthesis. Cladosporium sphaerospermum belongs to a group of fungi known as radiotrophic fungi. Radiotrophic organisms can capture and utilize ionizing radiation to drive metabolic processes. In radioactive sites like Chernobyl, where conventional cleanup methods are challenging and hazardous, radiotrophic fungi can provide a safer, natural alternative, according to an April 2008 article published in FEMS Microbiology Letters. Scientists are exploring the feasibility of deploying these fungi to contain and potentially reduce radiation levels in contaminated areas.

Western Sikkim in India ... officially went 100 percent organic in 2016, and won what many regard as the Oscar for best public policies — the UN Food and Agriculture Organisation’s Future Policy Gold Award — in 2018. This change is necessary: An estimated 52 percent of agricultural land across the globe is moderately to severely degraded due to monoculture, chemical pesticide and fertilizer use, and groundwater extraction — and this will accelerate unless these practices change. Sikkim is India’s most sparsely populated state. Its mainly subsistence farms were, and continue to be, spread thinly across mountainous terrain, which makes supplying inorganic fertilizers expensive. Consequently, using homegrown organic manure and vermicompost (compost created from worm waste) was very much the norm. It also helped that the local populace already understood the value of organic food. “As children, we were taught that basti (local) vegetables grown without any chemical inputs by small farmers, were the best vegetables to eat,” says Renzino Lepcha, CEO of Mevedir, an organic agri-business and certification agency in Sikkim. [Former] chief minister Pawan Chamling wrote, “[W]e have not inherited this earth from our forefather but have borrowed it from our future generations, it is our duty to protect it by living in complete harmony with nature and environment.” Rain-fed agriculture has helped reduce the need for irrigation and conserve water. Some reports suggest that since 2014, bee populations have been rebounding, with yields of pollinator-dependent cardamom increasing by more than 23 percent.

Venture into New Mexico's beautifully stark high desert and you may well stumble across some fantastical and unconventional homes – some palatial and sculpturally rounded; others with an ancient temple-like form – that look like they're from a Star Wars movie. Set in and around the town of Taos where they were invented almost 40 years ago, these are Earthships: net-zero, sustainably designed homes built mostly from both natural and waste materials, such as old tyres, empty wine bottles and wood and mud. Earthship construction requires less in the way of toxic or carbon-emitting construction materials like concrete and plastics, and doesn't require precious woodland and other natural resources. An earth berm (a purposefully built bank of soil) surrounds the Earthship on three sides, providing insulating mass that controls temperature. Each has a greenhouse ... either on the north or south side depending on location. Most Earthships are purely solar powered; some also have wind turbines to supplement or a wood-burning stove as back up. Taos has cold snowy winters and often dry, hot summers, but in an Earthship, the internal temperature remains close to 72F (21C) year-round, regardless of outside weather conditions. What does it feel like to stay inside an Earthship? "It feels like you're inside the womb," says Earthship construction manager Deborah Binder. "You feel constantly hugged and snuggled. The temperature is always comfortable."

[Robert] Brito and his family, who live along the Rio Negro in the Brazilian Amazon, only saw the monetary value of logged trees. Now, when Brito looks at a tree, everything has changed. "We stopped thinking about price and started thinking about [a different kind of] value. For example, when I see a beautiful cumaru [Brazilian teak] tree, 300 to 400 years old ... I still touch it, but with a different mindset. I have access to education, technology, a future for the young people living here, and I still contribute to the preservation of our planet in relation to climate change." Brito's transition ... required the support and alignment of financial, social and environmental incentives. In 2008, the government of the Brazilian state of Amazonas created the Rio Negro Sustainable Development Reserve, in order to preserve nature and to support communities living within it. The designation of the sustainable development reserve led to organisations including the Foundation for Amazon Sustainability (FAS) establishing education and health projects there. Brito recalls that one day Virgilio Viana, the director general of FAS, suggested that he might like to work in community-based tourism. "I started receiving people in my own home," Brito says. This trial was a success. He realised that he earned more in a week than he had ever seen in three months of logging. In 2011 – three years after the creation of the sustainable development reserve and over two decades since he cut down his first tree – Brito opened his nature lodge. And he put down his chainsaw. Moving away from blaming or shaming individuals can bring more people into the environmental movement. So can valuing people's prior experiences, such as Brito drawing on his decades of logging as he guides visitors around the forest in his flip-flops.

Leah Garcés considered Craig Watts her enemy. As CEO and president of the nonprofit Mercy for Animals, Garcés has devoted her life to protecting animals. When she met Watts in the spring of 2014 at his poultry farm in North Carolina, he was one those factory farmers she deeply despised. Watts had raised over 720,000 chickens in 22 years for Perdue, the fourth-largest chicken company in the US. He took out a $200,000 bank loan to build four giant chicken houses. Squeezed by Perdue’s profit margins, Watts struggled to pay the bills. Garcés realized that Watts was not her enemy, but an ally: Chicken farmers like him wanted to end chicken farming as much as she did. Yet because of his hefty loans, Watts saw no way out. Together, they released footage from the horrors of chicken farming in the New York Times. Watts has now become one of the poster farmers for the Transfarmation Project, which Garcés founded as an offshoot of the nonprofit Mercy for Animals in 2019. Ultimately, Garcés’s vision is not just “helping a few dozen farmers transition to a healthier and more sustainable model, it is about how we transition away entirely from factory farming.” The Transfarmation Project connects farmers with consultants and is producing resources and pilots to model successful transitions. In the same warehouse where Watts once had to kill chickens and where he and Garcés filmed the whistleblower video, he is now harvesting mushrooms.

Danielle Stevenson ... has been pioneering a nature-based technique for restoring contaminated land, using fungi and native plants to break down toxins like petroleum, plastics, and pesticides into less toxic chemicals. The usual way of dealing with tainted soil is to dig it up and cart it off to distant landfills. In a recent pilot project funded by the city of Los Angeles, Stevenson ... working with a team of UC Riverside students and other volunteers, significantly reduced petrochemical pollutants and heavy metals at an abandoned railyard and other industrial sites in Los Angeles. Stevenson says she believes her bioremediation methods can be scaled up to clean polluted landscapes worldwide. "Decomposer fungi can degrade petrochemicals the same way they would break down a dead tree," [said Stevenson]. "And in doing so, they reduce the toxicity of these petrochemicals and create soil that no longer has these contaminants or has much reduced concentrations of it. They can also eat plastic and other things made out of oil. People who live in a place impacted by pollution need to have a say in how their neighborhood is being cleaned up. We need to empower them with the tools to do this. That’s why along with doing these studies and pilot projects, I’ve been running workforce development programs. Potentially, they could bring economic opportunities and benefits to the community in addition to cleaning up the contaminated site."

About 100 miles southeast of Paris ... a charming stone aqueduct cuts across the green fields. “That’s the Aqueduct of the Vanne,” says [farmer] Zoltan Kahn. The Vanne, which supplies a fifth of Paris’s tap water, is fed by the water sources in these parts. The region is rich in biodiversity and has been a key drinking water catchment area for centuries. Since 2020, Eau de Paris, the city’s public water service, has been supporting farmers near its watersheds ... to reduce the use of pesticides and fertilizers on their crops. In other words, to go organic. When Kahn was approached by Eau de Paris with support to go fully organic, he jumped at the opportunity. In exchange for switching to organic, he would receive a so-called “Payment for Environmental Services” for each hectare of his farmland. As part of the €48 million ($51.8 million) project, Eau de Paris and the Seine-Normandy Water Agency, a public institution fighting water pollution in the region, are supporting 115 farmers based in watersheds that supply the city to either reduce their use of chemicals or go fully organic (as 58 percent of the farmers have). Already €32 million of that funding has been granted, according to Anne-Sophie Leclere, deputy director general of Eau de Paris. “It’s better for us to have cleaner, purer watersheds,” says Leclere. “This will save Paris from having to pay much more to process the water once it arrives in the city.”

Each year, US cities lose an estimated 36 million trees to development, disease and old age, many of which ultimately end up in landfills. Losing these urban trees — known to help cool their neighborhoods, lower carbon emissions and improve mental health, among other benefits — costs an estimated $96 million annually. In Philadelphia, a partnership is giving the City of Brotherly Love’s fallen trees new life. Philadelphia Parks & Rec joined forces with Cambium Carbon, a Washington, D.C.-based startup that repurposes waste wood, and PowerCorpsPHL, a local nonprofit that creates job opportunities for unemployed and under-employed 18- to 30-year-olds, to launch the Reforestation Hub. Rather than sending trees straight to the landfill or the city’s organic recycling center to simply become mulch or wood chips, the Reforestation Hub (which is co-located in the city’s organic recycling center) will salvage as many trees as it can. As many as possible will be turned into Cambium’s Carbon Smart Wood, which stores 5.23 pounds of carbon in each board foot. Fifteen percent of sales that come out of the hub will be donated to Tree Philly at the end of each year to support tree planting and maintenance across the city. While the hub formally launched only recently, in the year and a half that it’s taken to get the infrastructure in place, it has already diverted 542 logs to create 28,000 board feet of Carbon Smart Wood.

Trine Krebs is sometimes called “the leek woman,” or even Miss Dry-Legume, of Denmark. The 48-year-old has for decades traveled around the country as, in her words, a “food inspirer,” proselytizing about all things vegetables. So when, in October 2023, the Danish government published the world’s first ever national action plan for shifting towards plant-based diets, Krebs was ecstatic. The Danish government has three main goals: to increase demand for plant-based foods, to develop supply for plant-based foods, and to improve how all the different stakeholders — from scientists to farmers and chefs, food sociologists, and nutrition experts — in this nascent domestic industry are working together. Danish authorities see reducing meat and dairy consumption as key to reaching the Nordic state’s goal of cutting carbon emissions by 70 percent before 2030, when compared to 1990. The climate think tank Concito estimates that more than half of Denmark’s land is used for farming and that agriculture accounts for about a third of its carbon emissions. Yet a published in 2021 found that the emissions made by producing plant-based foods are roughly half the amount incurred by meat production. Denmark believes ... that the necessary shift toward plant-based eating also offers a massive economic opportunity. If the country were to gain a three percent share of the global plant-based food market, it could create up to 27,000 jobs.

Can you eat a diet that’s good for your health and good for the planet? A new study suggests that it’s possible. It found that people who ate mostly minimally processed plant foods such as nuts, beans, fruits, vegetables, whole grains and olive oil, along with modest amounts of meat, fish, eggs and dairy, had lower rates of premature death from heart disease, cancer and other chronic diseases. At the same time, their diets had a smaller environmental footprint because they consisted of foods that were grown using relatively less land and water and that were produced with fewer greenhouse gas emissions. The study ... was inspired by a landmark 2019 report from the EAT-Lancet Commission, which designed a “Planetary Health Diet” capable of sustaining 10 billion people and the planet by 2050. The planetary health diet, in broad strokes, encourages people to eat more plants and whole foods alongside small portions of meat and dairy. People whose eating habits most closely adhered to the planetary health diet were 30 percent less likely to die prematurely compared to people who ate the lowest amounts of foods that form the basis of the planetary health diet. Planetary health eaters had a 10 percent lower risk of dying from cancer, a 14 percent lower likelihood of dying from cardiovascular diseases, a 47 percent reduction in the risk of dying from lung disease, and a 28 percent lower likelihood of dying of Alzheimer’s disease and other neurodegenerative disorders.

Michel Costa had become a frustrated veteran of an obscure yet devastating war in Europe. The enemy: invasive Asian hornets, which had been massacring his honey bees. When Costa, a retiree and avid beekeeper, discovered a new weapon with the potential to change the course of the entire war, he was intrigued. Several companies had begun selling so-called “electric harps,” which they claimed could kill the hornets in droves by electrocuting them as they flew through. Although the harps take different forms, each one is made of some sort of large frame, which is then “strung” with conductive metal wires. These are then connected to a source of electricity, often solar panels, so that the wires conduct simultaneously positive and negative charges. When a hornet flies through, its wings touch the wires on either side, completing a circuit, and thereby delivering a fatal current of electricity. Beekeepers then place the harps around their hives in positions along the hornets’ frequent flight paths. The harps can reduce predation pressure by 89 percent — enough to give hives the chance to replenish their stores. In one study only 56 percent of unprotected hives survived through winter, while 78 percent of those protected by harps did. Harps are also cheaper than other methods for beekeepers to install and operate. Beekeepers can buy them in complete kits that cost around $300 ... as Costa did. When combined with solar panels, maintenance costs are minimal.
