  • Looks swell

    Carnegie Wave Energy created a system to generate electricity from the ocean’s waves to power Australia’s largest naval base. The system, known as CETO 5, has buoys bobbing up and down below the ocean’s surface that drives a pump attached to the seafloor and pushes water through a pipe to the power station. Each buoy can create 240 kilowatts, and all together the system produces about 5 percent of the base’s electricity. The system will need to be upgraded if they plan to put buoys further at sea where the swells are greater.

  • Reclaiming Appalachia: A Push to Bring Back Native Forests to Coal Country

    Tearing down trees to save a forest? While that may not sound like a solution, it could in fact be the key to restoring the former forest that inhabited the Appalachian region in the Eastern United States. “Ripping so deep might seem extreme, but it’s the only way to give these native trees a chance,” says Chris Barton, co-founder of non-profit Green Forests Works and a professor specializing in forest hydrology and watershed management, by means of explaining the ongoing effort he and other researchers, scientists and non-profits are making to reclaim native forests in this region.

  • On the Delaware, A Promising New Era in Cleanup of an Urban River

    Once known for being dirty, the Delaware River is being cleaned up by nonprofits and government entities to the point where they’re encouraging people to swim in it again. The Camden County Municipal Utilities Authority diverted the flow of sewage at 52 municipal plants to a new treatment plant, which has kept 15 million gallons of sewage out of the river each day. While overflows have not been completely eliminated, a national advocacy group even named the Delaware its River of the Year because of its improvements in water quality.

  • Can charcoal make beef better for the environment?

    An unusual mixture of biochar — a charcoal-like substance that is produced by burning organic matter — and dung beetles is one way farmers could reduce their cows’ methane emissions to combat climate change, while also improving the health of their soil. Studies on Doug Pow’s farm in Australia have shown an improvement in soil-water retention and an increase in the amount of carbon retained in the soil, which prevents it from escaping into the atmosphere. “We are doing our bit to re-engineer the soil in a positive way, for the long-term benefits of our world,” Pow says.

  • For a Warming World, A New Strategy for Protecting Watersheds

    As climate change alters environments across the United States, it has become increasingly important to manage watersheds as a preventative measure to wildfires. Amid responses across the country, one private-public partnership, the Rio Grande Water Fund, is leading the way, demonstrating enough success that the model has become federal policy. The Fund brings together government agencies, NGOs, businesses, and residents to fund watershed restoration which, in turn, creates jobs and build more resilient ecosystems.

  • Hold the Salt: The Promise of Little Fresh Fishes

    In Myanmar, aquaculture production from medium-sized freshwater farms is growing and could be an important and sustainable supplier of food for the world’s growing population. Aquaculture businesses are thriving in Southeast Asia despite the decline of wild fisheries — the acreage of cultivated fishponds in some regions has expanded by more than 250 percent. While some environmentalists argue that it damages ecosystems, research suggests that freshwater aquaculture have a much lower environmental impact than marine fish farming.

  • The David And Goliath Story Playing Out In Alaska's Fisheries

    A small, southeast-Alaskan fishing community banded together to protect the source of its livelihood from industrial fishing. Legislation officially protected 70,000 square miles of pristine waters in 1998. The ban on industrial fishing has resulted in much smaller, sustainable fisheries that have kept the ocean habitat flourishing and business booming for local fisheries. A cooperative model prevents overfishing and maintains a healthy ocean habitat.

  • Pee fanatics want to feed the world with your liquid gold Audio icon

    A French startup is turning urine into an environmentally-friendly fertilizer that could replace chemical products. Early tests suggest that the urine mixture created by Toopi Organics can compete with synthetic fertilizers, which end up in waterways and can alter lake and river ecosystems. While the organic fertilizer requires a significant amount of urine to make, it could be a viable alternative to grow crops.

  • Saving Mowers and Wildlife

    After the Vermont Agency of Transportation had to release more than 50 northern water snakes that were entangled in plastic erosion control netting alongside a road, the department looked for other products that could get the job done while also protecting wildlife. Many states, including Vermont, have switched to more biodegradable options that use natural fibers and found that there hasn’t been a difference in performance and haven’t seen any wildlife mixed up in the new netting.

  • Making A Milwaukee Beach Accessible

    An organization in Wisconsin is making public spaces accessible to people with disabilities. Their work has resulted in one of the most accessible beaches in the nation. Bradford Beach in Milwaukee now has a permanent ramp all the way to the waterfront, making it more inclusive of those who couldn't previously enjoy being by the water.
