‘Our biggest challenge? Lack of imagination': the scientists turning the desert green

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.

From collecting plastic to transforming it into infrastructure, communities all over the world are implementing solutions to tackle the growing amount of plastic waste. In Malawi, women are separating garbage from plastic and creating new products like fire briquettes, doormats, and organic compost that they can sell to others. A town in Tasmania turned their plastic waste into a road made of recycled asphalt that is expected to last 15 percent longer than regular asphalt. And Zimbabwe is employing youth to recycle plastic into eco-friendly construction materials.

A new county initiative in Colorado aims to support regenerative agriculture projects on farms as a way to take carbon from the atmosphere and store it in the soil in an effort to combat climate change. Restaurants donate 1 percent of their profits to the Restore Colorado initiative in Boulder County. The McCauley Family Farm is one of the first to sign on to this initiative and plan to plant more trees on their grazing land. While it can take years to see any benefits, organizers are looking to scale the initiative to be statewide.

The government of the Philippines is working with the Masungi Georeserve Foundation to restore wildlife and forests in a 2,700 hectares area of degraded land. They use a technique that focuses on the nurturing of native trees through natural practices. While the method takes longer to reforest an area than traditional ways, the initiative has planted 60,000 trees and employed 100 park rangers from the local communities that help protect the reserve.

As governments and businesses make pledges to cut their carbon emissions, planting tress has become a popular solution to combat the effects of climate change. But tree-planting schemes take time and proper management to actually be effective. Many efforts have failed to take some key factors into consideration, including types of trees, location, and even community-involvement.

The Colombian government has been working with regional regulatory agencies, the World Wildlife Fund, and local forest communities to encourage sustainable timber production and the implementation of forest management plans. They launched the Legal Wood Pact — a commitment with 69 entities to exclusively use wood from legal sources. While it can be difficult to convince people to purchase sustainable timber that’s more expensive, the sales of legal timber in the country increased from $500,000 in 2011 to $13 million in 2018.

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.

Solar development can reduce or significantly alter local biodiversity, and this should be considered when planning sustainability projects in the desert, argues a new study. Scientists measured the impact of a solar plant built in California and found that while some grasses and native shrubs grew back, cacti and yucca didn’t fare well. They recommend building solar projects on places that have already been developed or have low environmental impact. Groups like the Nature Conservancy are using that advice to pilot a project demonstrating that old mine sites in Nevada can be used for clean energy.

Ranchers and conservationists in Florida are working together to lobby for policies that preserve their farmland, protect wildlife species, and conserve water instead of turning it over to be developed. The Sunshine State has experimented with conservation incentive programs like payments for panther habitat restoration, reimbursements for livestock losses, and water storage projects but most of these programs have had mixed success and are often underfunded.
