  • Metering Utah's secondary water may help overuse in drought

    Cities in Utah are installing secondary water meters to track how much water residents are using on their lawns. This allows residents to see their usage, compare it to the recommended amount, and cut back when necessary.

  • Lessons From Latin America

    In 2021, a wave of national demonstrations swept Colombia in protest of worsening economic conditions in the country and other impacts of the COVID-19 pandemic, with the movements bolstered by uniting rhetoric about collective rights. Activists have since celebrated the election of the country's first climate-focused leftist government and the official decriminalization of abortion up to 24 weeks following a successful lawsuit spearheaded by organizers.

  • In the US West, Researchers Consider a Four-Legged Tool to Fight Two Foes: Wildfire and Cheatgrass

    Scientists are experimenting with a low-cost way of combatting an invasive species and wildfires. They’re using cattle to graze on cheatgrass, which has spread across the U.S. West, disrupted native plants and animals and become a source of fuel for fires. The cows were able to reduce the grass by an average of more than 60 percent, creating an area that could prevent fires from spreading.

  • Could Human Pee Be the Key to Saving Seagrass?

    As ecologists look to protect failing seagrass ecosystems, they have turned to a surprising solution: crystallized human urine. In a lab study, seagrass treated with struvite — a crystalline substance formed from human wastewater — had five times more seagrass shoots than those treated with regular fertilizer. It’s difficult to get struvite commercially and it might not work in all types of environments, but if there is more of a supply, this part of human waste could help an important ecosystem.

  • Seaweed Inc.: As climate threatens lobster, Maine eyes new cash crop

    As harvesting lobsters becomes more uncertain along the Maine coast due to climate change, many fishers are turning to kelp farming as a way to diversify their income. Atlantic Sea Farms purchases 1 million pounds of kelp a year from dozens of farmers resulting in The Pine Tree State becoming one of the top aquaculture producers in the United States.

  • Climate change: 'Sand battery' could solve green energy's big problem

    A team of Finnish engineers havevinstalled the first commercial battery made of sand, which can store green energy in it for months. Solar panels or wind turbines generate electricity, which is then stored as heat in the sand battery. When needed, the battery can discharge hot air to heat up water which is then used to heat homes, offices, and a swimming pool. This solution may be difficult to scale, but it’s a low-cost storage idea that could be useful when it’s cold and energy is more expensive.

  • As North Carolina warms, one farm is turning to a tropical crop: Taro

    Farmers in North Carolina are turning to tropical crops like taro to diversify farming and become more resilient to climate change. But, to sell taro consumers have to know how to cook it, so the Utopian Seed Project provides information for farmers and chefs on how to do just that.

  • Trees, tech and people help Mozambican park reverse nature losses

    Gorongosa National Park is a leader in community-driven conservation efforts. Last year, surrounding communities planted more than 260,000 coffee trees and 20,000 indigenous trees. The park has also led to employment for 1,500 locals, in an effort to protect the environment and keep the local economy afloat.

  • Soilless Farming to the Rescue. How to Boost Agriculture Without Hurting Forests

    A Nigerian agricultural entrepreneur is embracing hydroponics — a method that grows crops with water and no soil — as an alternative to farming methods that have led to land degradation. Because of Adebowale Onafowora’s knowledge, he has trained more than 20,000 people; and helped set up over 200 hydroponic centers. His inspiration led to the establishment of the Landmark University Greenhouse and Hydroponic Technology Centre, a place for research and training in the technique.

  • As Temperatures Rise, Farms Are Sprouting in Alaska

    Alaska usually imports most of its food, but due to supply chain issues and climate change making the growing season longer, more small farms are popping up in The Last Frontier state. While the number of U.S. farms has decreased between 2007 and 2017, Alaska saw them increase by 44 percent. With their farming boom, residents are becoming more sustainable on their own crops rather than relying on global food systems.
