  • Maryland Town Turns Flood Zone into a Tourist Attraction

    When algae overgrowth began to plague the Carroll Creek flood control project, a group of volunteers cultivated 1,000 floating canopies of plants to block the sunlight that algae need to grow, allowing the community to maintain the effective underground concrete conduits that move storm water. 250 volunteers maintain the plants throughout the year and the creek, previously made unusable by the algae, now draws tourists to see various attractions.

  • How Canada's first Indigenous coast guard program is already saving lives

    The Canadian Coast Guard is building a working relationship with indigenous communities that live on the coast of British Columbia, in order to better coordinate rescue efforts. The indigenous tribes "have intimate knowledge of the geography, which allows them to expertly respond to emergencies on the water." The result has been the formation of the Coastal Nations Coast Guard Auxiliary.

  • 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.

  • 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.

  • Through Crowdfunding, An Initiative Helps Communities Access Clean Water

    Through the #BuildAWell project, the Water the Needy Foundation uses crowdfunding to build wells, boreholes, and manual hand pumps in Nigerian communities without consistent access to clean water. The organization has worked with more than 400 communities since 2017 and contracts with local workers to encourage a sense of community responsibility for the projects and ensure ongoing maintenance of the wells.

  • Flood control goes green: How Houston is using nature to combat flooding

    Several areas in Texas are using public green spaces and nature preserves as ways to mitigate or reduce flooding. Exploration Green is one example of a project that reclaimed nature in an urban area by creating five ponds, each of which can hold up to 100 million gallons of floodwater while also supporting native plants, animals, and trails for hiking.

  • A Conservation Project in Jamaica Puts Community First

    The Oracabessa Fish Sanctuary, created with input and buy-in from local fishers, manages and maintains coastal fisheries by employing fishers, captains, coral gardeners, supervisors, managers, and board members. The crew runs educational programs, has planted 18,000 corals and released over 20,000 sea turtles every year, established a sea urchin nursery, and patrols sanctuary borders waters to ensure compliance with the sanctuary policies. The Sanctuary generates enough money to employ 18 people, creating a loop where nature helps support those who nurture it.

  • 'Ventilation Corridors' Funnel Cool Mountain Air Into Steamy Stuttgart

    Stuttgart is using a “nature-based response” to climate change by leveraging earth-cooling tools already available in the natural world. The city has created a vast network of ventilation channels – green parkways and corridors of water and trees – designed to funnel cooler breezes into the city at night and naturally lower air temperatures.

  • The Eco-Friendlier Future of the Disposable Spork

    A clean-tech startup in Germany is producing sustainable food packaging out of agricultural waste as an alternative solution to single-use plastic. Bio-Lutions claims its products are compostable and uses less water than other products, but the material used won’t work for some food items like hot beverages. The company already has investors such as Delivery Hero that will use its products when the factory is producing compostable packaging.

  • Oregon Is Turning Sewage into an Endless Supply of Green Energy

    A wastewater treatment plant in Oregon not only cleans water that is released into the local river, but it also creates fertilizer that is sent to farmers to use on non-food crops and it produces renewable power from methane. The green energy created at the plant heats five buildings on the site and produces half of the energy the facility uses. This kind of co-generation system is growing in other places in the United States, China, Brazil, and Norway.
