Gardening and community gardens can be ways for immigrant and refugee communities to supplement their pantries by growing their own food, especially culturally appropriate food that is not readily found in grocery stores. It also helps people send literal roots down into a new place while maintaining a connection with their homeland. The Arab American National Museum (AANM) has created a new heritage garden on its roof with donated seeds, cuttings, and plants from local Arab American community members around Dearborn, Michigan. These include plants with a connection to the Arab world, but also plants from Michigan that have become meaningful to the Arab American community here. Accompanying the plants in the garden are oral histories of those community members about what gardening means to them, collected by the museum’s community historian. In Ann Arbor, Michigan, Phimmasone Kym Owens ... said, ‘Why don’t I create a garden for refugees?’” In 2021, Owens reached out to Jewish Family Services of Washtenaw County. They formed a partnership to create an innovative refugee-to-refugee community garden program ... and to work with refugees and grow culturally appropriate vegetables. “What sold this as being different is giving autonomy to the clients,” Owens said. “So we had a vote. They voted [for] Freedom Garden. And that’s a name that says it all. The fact that they chose Freedom Garden says exactly what you know, being a refugee, what you want.”

Food costs, especially in times of inflation, can be exorbitant. Likewise, getting to a brick-and-mortar grocery store may well be logistically impossible due to health and/or mobility concerns. It’s also true having limited access to food may be detrimental not merely because a person lacks basic sustenance, but also because certain medications work only when taken with food. Without it, those drugs may cease to work as effectively, if at all. Founded in 2016 in Copenhagen by five entrepreneurs, the team at Too Good To Go is trying to curb food insecurity around the globe by fighting food waste. On its website, Too Good To Go (TGTG) reports 2.8 billion tons of food is wasted every year. The app, available on iOS and Android, features a number of partner businesses—bakeries, supermarkets, and restaurants—nearest a user’s location that are giving away so-called “Surprise Bags” of unsold food. Rather than perfectly good food wasting away in a waste basket somewhere, TGTG users can stop by said businesses and pick up the food for themselves. The app’s UI is similar to those of on-demand food delivery services like ... DoorDash, UberEats, and Postmates. Users are able to see which places are available, what they may get, and then sign up to pick up the items at a designated time. To date, TGTG boasts 4.2 million users and 9,790 businesses on its platform. Earlier this month, the company ... announced they are carbon neutral and have saved 100 million bags in the last seven years.

Joost Bakker believes a house can be more than a place to live: it can be a self-sustaining weapon against the climate crisis. A new Australian documentary explores his bold blueprint. Bakker – a multi-disciplinary designer, no-waste advocate and the film’s eponymous protagonist – has long been something of a provocateur. In 2020, the Dutch-born, Australian-raised designer’s two decades of high-concept sustainability projects came to a head when he hit go on the construction of Future Food System. Erected in one of the busiest areas of Melbourne, the off-grid, three-storey house and urban farm produced all of its own power and food. Even the cooking gas was generated from human and food waste. “We can have it all,” Bakker [says]. “We can have houses covered with biology, plants, ecosystems and waterfalls. It’s not necessary for us to be destroying the planet or killing each other with materials that are making us sick. The infrastructure is already there. It’s just about reimagining our suburbs and reimagining our buildings.” Shadowing Bakker throughout the project from set-up to pack-down, was film-maker Nick Batzias ... who squeezes plenty of action into the pacy 90-minute documentary. The bulk of the film focuses on the building’s green-thinking initiatives. Steam from the showers is used to grow mushrooms; the foundation-less building is anchored by self-watering garden beds filled with 35 tonnes of soil.

[Pamela] McGhee and her neighbors are participating in a pilot program to build zero-waste systems for Detroit. It’s something they say the city sorely needs. For decades, Detroit was home to one of the country’s largest waste incinerators. East Side residents formed Breathe Free Detroit, one of several groups behind a successful campaign to shut down the incinerator; the plant closed in 2019. Now, that same group is working with the city to develop a composting system. Many ... see a direct line between composting and recycling and improving their community health. According to the Environmental Protection Agency, food waste is the most common material found in landfills and sent to incinerators in the U.S., comprising 24% of landfill materials and 22% of combusted municipal solid waste. But Detroit organizers didn’t have much experience with communitywide composting, so when they began developing a program, they turned to an unlikely mentor more than 8,000 miles away: the Mother Earth Foundation in the Philippines. Over the past 20 years, the organization has earned a reputation for training low-income communities, government agencies, civic organizations, and businesses in zero-waste practices. The two groups organized monthly calls, in which Mother Earth Foundation organizers offered advice based on their experiences setting up community composting systems. Members of Mother Earth Foundation and community organizers in Detroit plan to visit each other’s cities early next year.

When a dormant pecan farm in the neighborhoods of south Atlanta closed, the land was soon rezoned and earmarked to become townhouses. But when the townhouses never came to fruition and with the lot remaining in foreclosure, the Conservation Fund bought it in 2016 to develop an unexpected project: the nation's largest free food forest. Thanks to a US Forest Service grant and a partnership between the city of Atlanta, the Conservation Fund, and Trees Atlanta, you'll find 7.1 acres of land ripe with 2,500 pesticide-free edible and medicinal plants only 10 minutes from Atlanta's airport. The forest is in the Browns Mill neighborhood of southeast Atlanta, where the closest grocery store is a 30-minute bus ride away. "Access to green space and healthy foods is very important. And that's a part of our mission," says Michael McCord, a certified arborist and expert edible landscaper who helps manage the forest. The forest is part of the city of Atlanta's larger mission to bring healthy food within half a mile of 85% of Atlanta's 500,000 residents by 2022, though as recently as 2014, it was illegal to grow food on residential lots in the city. Resources like the food forest are a rarity and necessity in Atlanta as 1 in 6 Georgians face food insecurity, 1 in 3 Browns Mill residents live below the poverty line, and 1 in 4 Atlantans live in food deserts. The forest is now owned by the parks department and more than 1,000 volunteers and neighbors are helping to plant, water and maintain the forest.

Australia will set aside at least 30% of its land mass for conservation in a bid to protect plants and animals in the island continent famed for species found nowhere else in the world, Environment Minister Tanya Plibersek said. Australia has lost more mammal species than any other continent and has one of the worst rates of species decline among the world's richest countries, a five-yearly environmental report card released in July by the government showed. That report showed the number of species added to the list of threatened species or in a higher category of risk grew on average by 8% from the previous report in 2016. "The need for action to protect our plants, animals and ecosystems from extinction has never been greater," Plibersek said in a statement. By prioritising 110 species and 20 places, Plibersek said the areas managed for conservation will be increased by 50 million hectares. Australia ... is home to unique animals like koalas and platypus although their numbers have been dwindling due to extreme weather events and human encroachment into their habitats. Koalas along much of the east coast were listed as endangered in February. Australia has been battered recently by frequent extreme weather events including the devastating bushfires in 2019 and 2020 in the east that killed ... billions of animals and burned an area nearly half the size of Germany.

Houseplant sales were skyrocketing among US millennials even before the pandemic, with a nearly 50% rise in sales between 2017 and 2019, according to the National Gardening Association. Now, many like [travel writer MaSovaida] Morgan see them as a necessary tool in fostering optimal work-from-home conditions. Experts say this desire to fill indoor environments with objects from the outdoors ties in to the growing movement toward 'biophilic design', which is a concept used to increase wellbeing through both direct and indirect exposure to nature. Biophilic design was a major office trend in the years leading up to 2020, when Amazon introduced spherical conservatories to its Seattle headquarters; Microsoft debuted treehouse conference room in nearby Redmond, Washington; and Facebook created a 3.6-acre rooftop garden at its Silicon Valley hub. Thanks to the pandemic, millions of [remote workers] now have the chance to create a work environment with their own wellbeing in mind. An increasing body of evidence shows that incorporating nature can help with things like decreasing stress and increasing productivity, creativity and attention span. Beyond adding greenery ... there are several other simple additions for optimising a home office, including light and colour. Natural light supports the circadian rhythms of the body, which regulate our sleep-wake cycle, as well as hormones. Those working in a ... dark environment can typically mimic natural light by incorporate a variety of lighting levels throughout the workday.

An unlikely natural ally in the fight against microplastics has been discovered. Researchers in China have found that invasive water hyacinths are adept at absorbing microplastics without harm to the plant itself. Experiments against a control group showed that plastics were mostly trapped on the outside of the water hyacinth's root systems. The few that get inside the plant are quickly separated before nutrients get to the leaves. Typically, plants exposed to microplastics suffer ill effects. Water hyacinths are native to South America. Two plants were able to produce 1,200 daughter plants in four months, according to one study. Any given population of water hyacinth can double in size in six days. Once dropped into a new foreign habitat, invasive species ... can squeeze out native species, reduce biodiversity, and eliminate vital ecosystem services. Not long ago, Arkansas had to issue a statement on the threat water hyacinths posed to agriculture. On the flip side, microplastics are a scourge. They'll often end up in the fish we catch, and once eaten by humans, they can cause problems with the endocrine, immune, and reproductive systems. Despite their rapid proliferation, it may still be worth strategically deploying water hyacinths. Other studies have shown that water hyacinths can also absorb heavy metals and agricultural runoff. Meanwhile, enterprising individuals have been able to take the excess biomass of the plants and turn it into briquettes and bioplastics.

What if your heating and cooling worked during power outages, and you could count on it becoming more efficient and climate-friendly over time? That's the promise of district heating and cooling or district energy, where entire communities share a heating and cooling system. That allows them to tap into many low-carbon energy sources they couldn't before, more efficiently than any individual building could. As governments look to tackle carbon emissions from buildings — the third largest source in Canada behind the oil and gas industry and transportation — it's an idea that more of them are considering and implementing. Peter Ronson is chief operating officer for Markham District Energy (MDE), a network in a Toronto suburb that heats and cools 14 million square feet in more than 200 buildings, including condo buildings up to 44 storeys tall, a hospital, data centres, hotels and two schools. Some, like the data centres, produce a lot of heat, while others may use lots of hot water. "We got all sorts of stuff on the system," Ronson said. "When [some are] throwing away energy, I can recover and give it to somebody else." That kind of heat-sharing is efficient. Excess heat in the system can also be stored (underground in water or rock, for example) ... and much more cheaply than electricity. All that means converting buildings that burn fossil fuels to district energy can potentially put less strain on the grid than electrifying individual buildings using heat pumps or baseboard heating.

Scientists have developed a new type of fuel cell that can provide endless power through electricity harvested from dirt. A team from Northwestern University in the US say the book-sized unit could be used to power sensors used in farming, as well as remote devices in the Internet of Things (IoT). The technology works by generating electricity from naturally-occurring bacteria within the soil, offering a sustainable and renewable alternative to toxic and flammable batteries. “These microbes are ubiquitous; they already live in soil everywhere,” said George Wells ... at Northwestern University. “We can use very simple engineered systems to capture their electricity. We’re not going to power entire cities with this energy. But we can capture minute amounts of energy to fuel practical, low-power applications.” The soil-based microbial fuel cell (MFC) is based on a 113-year-old technology first developed by British botanist Michael Cressé Potter, who was the first person to successfully generate electricity from microorganisms. It took until the 21st century for the first commercial applications to be proposed, with Foster’s Brewing using a prototype to convert the yeast in brewery wastewater into electricity. The latest fuel cell was tested in wet and dry conditions to power sensors measuring soil moisture and detecting touch, outlasting the power of similar technologies by 120 per cent.

When [city councillor] Alexandre Garcin dreamed up Zero-Waste Roubaix, it wasn’t sustainability he wanted to tackle, but the litter problem that plagued his city. Garcin sent out leaflets looking for 100 volunteers to participate in a free, year-long pilot programme that would teach them how to live waste-free. These familles zéro déchet, or zero-waste families, would receive training and attend workshops on topics such as making your own yoghurt and cleaning with homemade products, with the goal of halving their waste by the year’s end. Volunteers weren’t offered any direct financial incentives to participate – only the promise of helping solve the litter problem and protecting the environment. The project focused on creating an identity around zero-waste and assigning families quantitative waste-reduction targets – strategies that are proven to be effective in other contexts, and everyone got pretty straightforward guidelines – for example, “don’t buy more food than you can eat”. According to Garcin, it’s actually “not that difficult” to halve a household’s waste production. Composting gets you most of the way there, since organic waste makes up about a third of the average French family’s municipal waste by weight. Another third is glass and metal, a significant chunk of which can probably be kept out of the landfill through recycling, and 10% is plastic, much of which can be avoided by finding reusable alternatives to plastic grocery bags, cutlery, packaging and other single-use items.

The power's out. But on a street in India, there's a cash machine still happily dispensing banknotes. Thanks, in part, to burnt cotton. For this cash machine has a backup battery inside it – a battery that contains carbon from carefully combusted cotton. "The exact process is secret," says Inketsu Okina, chief intelligence officer at PJP Eye, the Japanese firm that made the battery. "The temperature is secret and atmosphere is secret. Pressure is secret," he continues. Okina does say that a high temperature is required, above 3,000C (5,432F). And that 1kg (2.2lbs) of cotton yields 200g (7oz) of carbon – with just 2g (0.07oz) needed for each battery cell. PJP Eye also touts the possibility of improving battery performance as well as making batteries greener. "Our carbon has a bigger surface area than graphite," says Okina, describing how the chemistry of the anode in their Cambrian single carbon battery allows for a battery that charges very quickly, up to 10 times faster than existing lithium ion batteries, he claims. The battery's cathode is made from a "base metal" oxide. Although Okina won't disclose exactly which one, these metals include copper, lead, nickel and zinc. The company claims to be working on a dual carbon electrode battery, where both electrodes are made from plant-based carbon. Other researchers are looking at using materials as diverse as corn waste and melon seed shells to generate new types of electrodes for use in batteries.

In South Los Angeles, Crop Swap LA volunteers and staffers harvested bags of freshly picked produce from the front yard of a residence. "Everything we're growing is nutrient-dense and the food remains in the neighborhood," says Jamiah Hargins, who founded Crop Swap LA in 2018 as a small monthly swap of surplus produce. After spending years in finance and consulting, Hargins decided to create a local food distribution system to address the fact that his neighborhood was a food desert, meaning most residents have little access to healthy food. It's now one of many Bipoc-led groups across the US that are reclaiming their agricultural heritage and redefining the local food movement by growing on traditional farms and unconventional spaces such as yards, medians and vacant lots as a way to increase food security and health in their own communities. There are similar groups run by communities of color across the US. After the Chicora-Cherokee community in North Charleston, South Carolina, was left without a grocery store for more than 10 years, Fresh Future Farm stepped in. Founded in 2014, the non-profit transformed a vacant lot into a flourishing urban farm that grows bananas, sugarcane, meyer lemons, satsuma oranges, collard greens, okra and tomatoes, among other crops. Two years later, it opened a sliding scale grocery store on the same property – the first one in the area in 11 years. The non-profit also teaches home gardening classes, which is inspiring a new crop of home growers.

Scientists have discovered more than 5,000 new species living on the seabed in an untouched area of the Pacific Ocean that has been identified as a future hotspot for deep-sea mining, according to a review of the environmental surveys done in the area. It is the first time the previously unknown biodiversity of the Clarion-Clipperton Zone (CCZ), a mineral-rich area of the ocean floor that spans 1.7m sq miles between Hawaii and Mexico in the Pacific, has been comprehensively documented. The research will be critical to assessing the risk of extinction of the species, given contracts for deep-sea mining in the near-pristine area appear imminent. Most of the animals identified by researchers exploring the zone are new to science, and almost all are unique to the region: only six, including a carnivorous sponge and a sea cucumber, have been seen elsewhere. One of the deep-sea animals discovered was nicknamed the "gummy squirrel", because of its huge tail and jelly-like appearance, he said. There are also glass sponges, some of which look like vases. The most common categories of creatures in the CCZ are arthropods, worms, members of the spider family and echinoderms, which include spiny invertebrates such as sea urchins, and sponges. "Our role as scientists ... is to provide the data," [biologist Dr. Adrian Glover] said. "Everyone who lives on this planet should be concerned about using it in a sustainable way. I see it as very positive that we can come up with a regulatory structure before mining takes place."

The Osa Peninsula on Costa Rica’s west coast occupies just 0.001 percent of the planet’s surface area, yet is home to an estimated 2.5 percent of all the biodiversity in the world. Inhabited by jaguar, tapir and close to 400 species of birds, the forests here — and others like them around the world — combat biodiversity loss and play a key role in capturing carbon and fighting climate change. “For us it has been important because before, we protected [the forests], we looked after them, but we didn’t receive anything for it,” says Lineth Picado Mena, a rural farmer living on the peninsula and participant in the government’s Payments for Environmental Services (PES) program. “Now we can support ourselves with what we have.” By paying landowners for ecosystem services, the government incentivizes them to conserve the environment. That counteracts the market forces that put pressure on landowners to convert tropical forests to farmland or other land uses. In Costa Rica, the PES program’s annual budget is between $20 million and $25 million, of which 92 percent is funded from a sales tax on fossil fuels, while nearly six percent comes from water usage fees. This allocation is fixed and provides assurance that funds will be available each year. The remaining amount is collected through various government initiatives, such as carbon credits and public-private partnerships. The program ... is credited with turning Costa Rica’s deforestation rate from one of the highest in the world to a net reforestation.

At Radical Family Farms, Leslie Wiser recently planted bitter melons, what she refers to as “one of our most beloved crops”, a staple in many types of Asian cuisine that grows on a vine and is related to zucchini, squash and cucumber. Women like Wiser are increasingly the face of farming in California, and nationally as well. Experts say the growing presence of women in agriculture is having an impact on how the industry operates, especially in the face of generational challenges like pandemics and climate change, with research showing that women-led businesses are more likely to take a community-minded approach to how they operate and fill in gaps during crises. During the pandemic, for example ... women farmers filled the gaps in local communities for food access. Radical Family Farm stepped in to feed food-insecure seniors throughout the Bay Area when it was not safe for them to go to the grocery store or farmers’ market. “A lot of this was driven by the attacks on our Asian elders during the pandemic,” Wiser said. “It’s still happening, with seniors afraid to walk on the streets.” Her long-term goal is to dedicate one-third of the produce from her farm to seniors in the Bay Area. “It is part of my cultural heritage to honor our elders,” she said, adding that her grandparents on both sides took care of her growing up, so delivering “culturally relevant produce” to seniors is meaningful. “Instead of getting bags of potatoes, they can get vegetables, produce and herbs that are familiar to them.”

Near the southern border of the Pine Ridge Reservation in South Dakota, a curved translucent roof peeks out a few feet above the dusty plains. Below ground, at the bottom of a short flight of stairs, the inside of this 80ft-long sleek structure is bursting with life – pallets of vivid microgreens, potato plants growing from hay bales and planters full of thick heads of Swiss chard and pak choi. This is an underground greenhouse, or walipini, and the harvesters are members of the Oglala Sioux Tribe. It is one of at least eight underground greenhouses that, over the past decade, have been built or are being constructed on the reservation – which has one of the highest poverty rates in the US. Some hope they can help solve the interconnected problems of the lack of affordable, nutritious food and the difficulties of farming in the climate crisis. Today, more than half of the residents of Oglala Lakota county, one of three counties within the boundaries of the reservation, live below the poverty line. Food access is a huge problem. The 2.1m-acre reservation is classified as a “food desert” with only a handful of grocery stores. And health outcomes, including diet related diseases, are poor – about 50% of adults over 40 have diabetes. Neil Mattson, professor and greenhouse extension specialist at Cornell University’s School of Integrative Plant Science, says underground greenhouses could help to usher in more year-round food production across the northern US but they are still fairly new in the country.

When floods devastated Bangkok more than a decade ago, Thai landscape architect Kotchakorn Voraakhom became determined to help her sinking hometown fight this deadly climate threat. The floods "changed my life," said Voraakhom. "I started using the tools of landscape architecture (to tackle) climate change." The 2011 floods killed hundreds and displaced millions. "For us, climate change is primarily a water crisis," she said. "Our people can feel its impacts in their daily lives, each year through worsening floods, rising sea levels, and severe drought." In many sinking cities, including Bangkok, the current urban infrastructure is not fit for purpose and is "reducing our ability to adapt," said Voraakhom, noting that many of Bangkok's waterways and canals have been destroyed or have fallen into disrepair. "For us, as a city of water, the only way is to go back to our amphibious culture and reclaim the relationship with water." The architect said she integrates nature and water into her designs to create landscapes that help alleviate flooding and add greenery to densely populated cities. Voraakhom also created Asia's largest rooftop farm, Siam Green Sky, transforming 22,400 square meters (241,000 square feet) into a lush haven. The farm, which recycles food waste from restaurants in the building below and uses it as plant fertilizer, also slows down, soaks up and stores large amounts of rainwater. It is then used to grow vegetables, herbs and fruit, as well as rice.

Ants can be more effective than pesticides at helping farmers produce food, according to new research. They are better at killing pests, reducing plant damage and increasing crop yields, according to the first systematic review of ants’ contributions to crop production. Ants are generalist predators and hunt pests that damage fruits, seeds and leaves, leading to a drop in crop yields. A greater diversity of ants generally provides more protection against a wider range of pests, the study found. The analysis looked at 17 crops, including citrus, mango, apple and soya bean in countries including the US, Australia, the UK and Brazil. “In general, with proper management, ants can be useful pest controls and increase crop yield over time. Some ant species have similar or higher efficacy than pesticides, at lower costs,” researchers wrote in the paper published in Proceedings of Royal Society B. There are more ants than any other insect, making up half of the planet’s insect biomass. There are at least 14,000 known species of ant, with many more likely to remain unknown. Citrus growers in China have used ants in farming for centuries, and the insects have also been used to help control forest pests in Canada, cocoa pests in Ghana and crop pests in Nigeria. Dr Patrick Milligan, from the University of Nevada Pringle Lab ... said the findings were “both heartening and not at all surprising”. He added: “They offer a neat and tidy description of ant-derived benefits that are ubiquitous across ecological and agricultural systems.

Popcorn could soon be used to create sustainable insulation for buildings, replacing the current non-biodegradable materials. Scientists have invented a method to create sustainable building insulation boards using “granulated” popcorn with “excellent” thermal insulation properties and good protection against fire. The plant-based, environmentally friendly material is a sustainable alternative to current building insulation products that are derived from petroleum, said scientists from the University of Göttingen in Germany. About 90 per cent of the materials currently used to make insulation for buildings are made of plastics or mineral fibre, which are non-biodegradable, according to the scientists. These materials generate carbon dioxide during their manufacturing stages and are also rarely recycled when a building is torn down, contributing to pollution and making them unsustainable. Conventional insulating materials made of polystyrene also tend to damage the environment, the scientists pointed out. On the contrary, the researchers said, granulated popcorn is similar to polystyrene and just as lightweight, without having the synthetic material’s downsides. “This new process, based on that of the plastics industry, enables the cost-effective production of insulation boards at an industrial scale,” Alireza Kharazipour, head of the research group from the University of Göttingen, said in a statement.
