  • 'Cool pavement' experiments help urban planners find ways to ease rising temperatures

    To combat the effects of rising temperatures due to climate change, Los Angeles piloted an experiment called “cool pavements,” where they coat streets with a light-colored sealant to reflect heat. Researchers are studying how effective this method is at reducing the urban heat island effect. Using a mobile sensor station, they found mixed results: While the surface temperature of the road was cooler, a person could feel warmer on the reflective roads. Figuring out how to balance different heat-mitigating strategies could be helpful as cities like Phoenix figure out how to implement cooling infrastructure.

  • The Business of Burps: Scientists Smell Profit in Cow Emissions

    A company called Mootral is studying whether changing a cattle’s diet could make the animals belch and flatulate less methane. They created a food supplement out of compounds from garlic, citrus, and other additives, that in early tests, has shown a decrease in a cow’s emission of the greenhouse gas. If they can get investors on board and scale it to different breeds of cows and in different climates, it could help the agricultural and farming industries to combat climate change.

  • Working to recover the ocean ecosystems that sea urchins gobbled

    In partnership with the company Urchinomics, a lab in California is developing a type of feed that helps sea urchins captured in the wild grow so they can sell them for commercial purposes. Sea urchins have been ravaging bull kelp forests along the coasts and scientists are looking to sustainably control the urchin population. The algae-based feed that scientists produced helps the urchins grow and produce uni — the urchin’s edible gonads — which are sold to restaurants, and a test run of the product in Japan was well-received.

  • Here comes the sun canoe, as Amazonians take on Big Oil

    The Kara Solar Foundation is looking to connect indigenous communities in Achuar territory in Ecuador to learn about solar power as an alternative to oil. By building solar-powered canoes, they can replace vessels that burn fossil fuels into the atmosphere. While the two boats in operation have run into technical problems, the intercultural training programs are instructing Achuar people on how to fix the technology. “Sustained and truly intercultural collaborations can create technological solutions that serve indigenous communities, rather than destroying them,” says Oliver Utne, the foundation's founder.

  • In Kenya, herders turn an invasive cactus into biofuel

    The invasive prickly pear cactus is spreading over grazing lands in Kenya and is harming herders’ livestock. So a local environmental science graduate is testing a system to turn the cacti into biogas. While the system can be expensive to install, the gas can be used for cooking and fertilizer, which can free up time for pastoralists and reduce the amount of firewood used. The graduate is training eight women’ groups to use the system.

  • Alaskan Roulette

    An initiative called the Southeast Alaska Tribal Ocean Research is the state’s first coordinated testing effort to ensure that harvesters are not selling shellfish that contain paralytic shellfish poisoning. The program keeps track of data from 42 beaches in southern Alaska. However, the program only covers a small part of the active fishing sites in the state, so data is limited. But since the testing program was set up, no one at those sites have become sick.

  • University of Notre Dame converts tons of dining hall leftovers into energy

    The University of Notre Dame installed three Grind2Energy systems, which aims to reduce the amount of food waste from the campus’ dining halls. The systems process the waste and send it to a local dairy farm where they break down the material to produce biogas that is used to generate electrical power for 1,000 homes each day in Plymouth, Indiana. While not everyone at the university has committed to the sustainability efforts, these systems can be scaled to be used on other college campuses.

  • Montana's Grand Prairie Experiment

    According to the WWF, 69 percent of the Northern Great Plains remains untilled, providing great opportunity for making sure that land remains untouched. Two conservation organizations, the Nature Conservancy and the American Prairie Reserve, are butting heads as they both try to preserve the land, albeit via different means. Although they both face opposition for their methods, this article lays out exactly how both have already managed to make great strides in conserving the land and increasing biodiversity.

  • Can rationing carbon help fight climate change?

    As countries wrestle with how to reduce their carbon emissions, grassroots carbon rationing experiments are taking shape around the word. On an Australian Island of 800 people, a quarter of them participated in a test that calculated their carbon footprints with a goal of reducing their fossil fuel use by 10 percent. The average household reduced their usage by 18 percent and almost two-thirds of participants wanted to continue. Other experiments in Finland and the United Kingdom have taken place, yet some question if carbon rationing is equitable.

  • PowerCorpsPHL trains Philly youth for careers that have a future

    A workforce development initiative, PowerCorpsPHL, pays participants to learn skills and gain hands-on experience for jobs that offer long-term career opportunity in the field of environmental sustainability. Participants generally have criminal records or have been in the foster care system. In addition to job training and education, PowerCorpsPHL also provides services such as mental health counseling, securing childcare, navigating SNAP and AmeriCorps tuition benefits and helping with paperwork. The program helps 92 percent of participants secure either a job or post-secondary education.
