Conservationists, government agencies, scientists, and landowners are working together to restore streams using low-cost solutions from sticks, stones, and even beavers. Restoring these floodplains is important to help communities combat drought and wildfires. In Idaho, scientists relocated nine beavers to Birch Creek so they could help repair the dried-up stream. In three years, the beavers built dams, which helped the creek flow for longer in the summer. This method might not work everywhere, so scientists have also tested stone structures, which also proved effective at improving the ecosystem.

Response Location: Netherlands, s’-Hertogenbosch

A Dutch group of engineers known as the Weather Makers has an ambitious plan to regreen the Sinai Peninsula — the stretch of desert connecting Egypt to the rest of Asia. Their efforts would restore forests, wetlands, and even adjust the weather for the region. This form of ecosystems regeneration could help with food security and mitigate the effects of climate change. Their process of changing an entire ecosystem can be controversial, but initial tests have shown how this could work on a large scale.

An insect that makes its home on eastern hemlocks in Nova Scotia has the power to wipe out the tree species if left unchecked. Scientists are looking to a strategy called biological control — a historically controversial approach — that would introduce a new predatory species to kill the insect. After rigorous lab testing showed a small black beetle only attacked their targets and didn’t disrupt other ecosystems, they released them in 2003 at an orchard on Vancouver Island. Results show they have been somewhat effective, but it’s unclear if it will completely solve the problem.

Response Location: United States, Jersey City, New Jersey

In a science class in a local New Jersey school, students came up with a green solution to a storm water management and flooding problem in their parking lot when it rained. With help from the Cooperative Extension Water Resources Program out of Rutgers University and funding from city agencies, they were able to build planters and install concrete to absorb the runoff. The project galvanized the community, encouraging the school to expand their STEM curriculum.

Response Location: United States, Lake George, New York

An experiment in upstate New York showed how town officials could maintain clean and safe roads during the winter season and protect the environment. By using a salt brine before winter storms, they were able to plow the roads more efficiently and, at the same time, reduce the amount of salt going into waterways that could impact freshwater ecosystems. The effort, launched by the nonprofit FUND for Lake George, required “a culture shift within the towns’ maintenance departments,” but the communities were able to cut their salt usage in half over two years.

Response Location: Somalia

A greenhouse that is cooled by seawater and the wind is allowing farmers in Somaliland to grow crops like tomatoes and vegetables despite extreme heat. By creating an environment that is higher in humidity and cooler in temperature, plants don’t need to drink as much water — almost 10 times less water because of the cooling system. There are challenges to scaling the response, but these greenhouses offer farmers the potential to increase their revenue in Africa.

As a way to combat climate change, scientists are experimenting with genetically modified trees as a way to draw carbon dioxide out of the atmosphere to store in its leaves, roots, and trunk. The startup Living Carbon has genetically modified poplar and pine seeds in the ground and expect them to be ready by the end of the year. Some scientists are worried about how these trees can impact forest ecosystems, but they grow faster than normal trees, allowing them to study and assess the risks quicker.

A unique partnership between the U.S. military, conservation groups, private landowners, and state and local governments has allowed the endangered red-cockaded woodpecker to grow in numbers. By working together, they’ve been able to protect the forests near military bases where these birds live. Environmentalists are worried about efforts to remove the birds from the endangered species list, saying their work isn’t over. However, this partnership has become a model for other conservation efforts throughout the United States.

Symbrosia, a clean-tech startup in Hawaii, is taking seaweed from the ocean and turning it into a powder that can be used to feed livestock to reduce the amount of methane they produce — a key contribution to greenhouse gas emissions. The company worked with an organic farm in Upstate New York to test the product and found that sheep given a high dosage of the supplement had up to 70 percent reduction in methane emission. Creating the powder takes weeks and a lot of steps, but the startup is hopeful the product can become a mass-produced commodity.

Response Location: United States, Tulalip, Washington

While beavers might seem like a nuisance to many, the Tulalip Tribes in Washington state — after a long legal battle — are relocating the creatures to their lands as a way to create healthy ecosystems. The tribe has spent two years successfully capturing beavers from private lands and moving them with help from the Cascade Forest Conservancy. Their work could become a model for other tribes as a way to reclaim their land management methods.
