  • 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.

  • 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.

  • Drought and inflation have come for farmers and ranchers. Does this Utahn have the solution?

    A new Hydrogen nutrition technology allows a rancher in Utah to turn alfalfa seed into cattle feed within a few days with less than one-tenth of the water used in traditional hay fields. By using this technology, he’s been able to manage the drought in the region and preserve his farmland. While many could be skeptical of the system, the Legislature is planning to study how effective it could be for others in the state.

  • How Stony Brook University Scientists Gave Shinnecock Bay a New Life

    After planting clams in Shinnecock Bay in 2012, scientists at Stony Brook University were able to reverse the trends of red tide in the coastal New York waters. The bay restoration project resulted in 400,000 square meters of seagrass regrowth and the local clam population significantly grew.

  • Carbon credits versus the Big Gulp

    By planting cattails and tule reeds in a California Delta farmland, scientists hope to change the area into a marsh with peat that can store carbon dioxide. This would also support levees from failing and prevent salty ocean water from ruining crops and threatening drinking water. Managing this kind of landscape can be expensive, and farmers are not always on board with converting their land, but this pilot project has already doled out 52,000 tons of carbon credit making it the first wetland project in the United States to do so.

  • How farmers in Earth's least developed country grew 200 million trees

    After years of drought and land-clearing that left Niger with few trees left, the country now boasts about 200 million trees, which have mostly been reestablished naturally. While the effects of climate change could threaten the future of these trees, this method has also increased crop yields in villages. This model of letting trees grow back with little human influence could be implemented in other countries.

  • Why a dry Chilean lagoon matters to the future of the Great Salt Lake

    Burdened by extreme drought, water diversions, and a lack of regulation, Lake Acuelo in Chile dried up. Now, researchers are learning from this slow-moving ecological disaster to help other lakes in trouble, like Utah’s Great Salt Lake.

  • Indigenous knowledge and science team up to triple a caribou herd

    A collaboration between two First Nations communities, scientists, private businesses, and the Canadian government are recovering caribou populations in British Columbia. Because of their work, they have been able to triple the number of caribou in their herd over the last decades. While their methods of protecting the animals are controversial, they’ve been able to protect more than 7,000 hectares of additional land for caribou habitat.

  • 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.

  • The ‘timber detectives' on the front lines of illegal wood trade

    At the Thünen Institute in Germany, a team of 15 people are working to identify culprits of the world’s third largest criminal sector: the illegal wood trade. Since 2013, they have been analyzing and identifying the origin of wood products to determine if they were made from endangered or protected tree species. In 2021, they analyzed about 10,000 samples and are working with organizations and authorities around the world to prevent illegal logging.
