  • The ancient technology getting a second wind

    Old ships, powered by the wind, are being refurbished to sail small amounts of cargo around the world. While there are only a few hundred still in use, newer ships and sails are being designed and built with new technology to make the vessels more fuel efficient and produce zero emissions. While many of them are in the prototype phase, some of these ships are able to go into smaller ports and harbors that larger vessels can’t reach.

  • 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.

  • Saving and protecting peatlands in Indonesia

    The degradation of peatlands is a public health and climate change issue. Organizations in Indonesia are working to understand these wetlands better by mapping the location of them throughout the country and around the world. By creating a comprehensive picture of peatlands, which contribute up to 10 percent of global anthropogenic greenhouse gas emissions, key partners can understand how to prevent carbon emitting from the wetlands into the atmosphere.

  • How a trickle of water is breathing life into the parched Colorado River Delta

    A unique partnership between environmental groups and governments in the United States and Mexico has led to the resurrection of wetlands and forests in the long-dry Colorado River Delta. Since the waters were dammed and diverted in the 1900s, estuaries dried up and vegetation was lost. The two nations agreed to rewet the delta via a planned flood. Even though there isn’t enough water available to restore a flowing river, these restoration projects on parts of the delta have shown promise. Challenges, including limited funds and hotter, drier conditions due to climate change, remain for its longterm success.

  • 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.

  • The Dutch have mastered water for a millennium. Could their new approach save New Orleans?

    As New Orleans and the Louisiana coast become increasingly vulnerable to rising sea levels, the city is looking to the example of the Netherlands in using nature as a tool in coastal preservation. In the Netherlands, the Maeslant storm surge barrier was built 23 years ago with the ability to block out waters to prevent flooding. In recent years, however, the Dutch have adapted: using green roofs, adding trees as an extra defense in front of levees, and looking to nature more and more to protect cities in the age of climate change.

  • How the Dutch Are Building Coastal Protection for Less — With Nature's Help

    As climate change threatens many countries’ coasts, the Netherlands embarked on an experiment to improve their storm and flood defenses. Called the Zandmotor, this beach project is a nature-based solution to protect the coastline from rising seas and more intense storms. This idea in water protection and coastal management could be helpful in Louisiana where they face similar threats from climate change, but finances and federal laws have proved a challenge.

  • 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.

  • 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.
