Could Akira Miyawaki's 50-year-old innovation help promote biodiversity and reduce the risk of climate change?

In Canada, farmers are rewilding their farmlands, a process where a farmer restores their habitat to a more natural state. It includes things like planting trees, building hedgerows, and creating ponds. Rewilding can prevent soil erosion, carbon sequestering, and filtering water, among many other things, reversing some of the adverse effects caused by farming. One non-profit, the Alternative Land Use Services is funding these rewilding projects by paying farmers. ALUS projects span 31,000 across Canada.

After being known as a polluted mining town, politicians, scientists, industry officials, and residents of Sudbury, Ontario, were able to come together to restore its land. After 40 years and $33.5 million, they are about halfway through recovering about 200,000 acres of land. So far, they’ve been successful at restoring air quality, neutralizing soil to allow for replanting, and restocking lakes with fish. While some locals think the mining companies should have done more, the collaborative spirit could be a model for other communities looking to improve the environment.

Landowners, state employees, environmental groups, and local hunters are working together to protect Hawaii’s forests and drinking water by eradicating invasive plants from the state’s protected forests. By allowing native plants to flourish, these forests could help combat climate change by sequestering carbon and allowing freshwater quivers to recharge with rainfall. Since 2013, the state has built 132 miles of fence to keep grazers away from forests to prevent the spread of seeds of invasive plants. However, this method can be expensive; a 1,400-acre fence cost over a million dollars.

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.

Deforestation, overgrazing, and increased carbon emissions are familiar challenges as climate change continues to threaten our food systems. Author Eric Toensmeier discusses how "carbon farming" - or practices such as agroforestry, improved annual crop rotation, and better grazing practices are not only good for farmers - increasing yields and reducing land degradation - but good for capturing carbon and environmental health overall. Toensmeier also discusses how to get more farmers to practice these methods: improved financial models, government support, and a certification system.

The state of Louisiana is disappearing at an incredible rate, and its sinking deltas threaten some of the nation's crucial oil, gas, and fisheries industries. Industry and government have created an unprecedented plan to save and rebuild these wetlands over the next 50 years — and say failure is not an option.

Collaboration between the Hmong community, researchers, and park authorities in northern Thailand has allowed them to work together to restore the forest in Doi Suthep-Pui National Park. Between 1997 and 2013, they used assisted regeneration to restoring 33 hectares of forest, which also increased the area’s natural flora and fauna. Because of their efforts, their approach is being implemented in tropical forests around the world, including Cambodia, Madagascar, and Tanzania.

Mangrove forests are known to be excellent storers of carbon and hosts of biodiversity, but they are also able to protect communities on coastlines from storm surge. However, many of the projects to restore these forests fail because they are rushed or planted in the wrong places. Scientists argue that organizers should focus on natural regrowth or “ecological mangrove restoration,” a science-based approach, which has been used in Indonesia and Guinea-Bissau.

A hit TV show in the 1970s and ‘80s called The Beachcombers brought the town of Gibsons and its logging practices into homes across Canada. After years of pollution and land degradation, it became one of the first towns in the world to incorporate nature into the municipality’s finances. Developers have to take stock of what natural infrastructure is on their property before they build. The town also launched an initiative to encourage other places to calculate the value of their green infrastructure. So far, 30 of them have signed up across the Great White North.

A blue carbon credit scheme in Kenya is not only restoring mangrove forests, but it’s also reducing environmental crimes and providing a way for residents to make money. The Mikoko Pamoja carbon project is a partnership that encourages the protection of mangroves in exchange for selling carbon credits. Since the project launched 2013, each year it traps the equivalent carbon emissions of about 650 cars. While it’s not a perfect system, it has inspired other blue carbon programs in other villages.
