The mangrove forests protecting the Pearl River delta: a photo journey

In California’s wildfire-prone Sierras, forest managers are turning to an ancient, if not quite intuitive, tool: more fire. In 2019, the Forest Service will manage 250,000 acres with controlled burns and “mechanical thinning,” using equipment to take out small trees. Though such plans face some hurdles, states across the country are adopting them, reducing wildfire severity while often benefiting ecosystems.

New DNA testing technology is showing promise as a faster, cheaper way to determine if a shark fin came from a protected species, an important task to curbing the illicit shark fin trade across the world. While experts warn that the technology won't act as a deterrent to the practice, it will help authorities better track and determine if shipments are suspect.

In the wake of more than 100 forest fires in Maule, Chile, hundreds of burned acres of forest are being replanted by three Border Collies named Das, Olivia, and Summer and an organization called Pewos. The dogs bound through miles of terrain with special backpacks that release native seeds to regrow the area. So far the dogs have worked in 15 forests in the region and plants are starting to come back.

In Jamaica, locally-led coral nurseries are working to restore the coral reef that have been lost to natural and manmade disasters. These organizations have small coral gardens where they can grow free of danger and when they’re big enough, are transported to a reef. With coral and fish being so codependent in the underwater ecosystem, the regrowth of coral has meant an increase of fish and fishing for the country, which many people rely on for their livelihood.

In Indonesia, transferring land management rights to local residents is slow-going, but one community is setting an example for what can happen when the residents are in charge. Mandiri farmers formed a cooperative and began replacing hillsides; now, tourism to the area has increased and attitudes towards the land and community have changed.

Coastal Shellfish, an Indigenous aquaculture company in British Columbia, is focusing on sustainable food and food security through its product Great Bear Scallops. This is the first project funded by the Costal Funds trust set up by donors, governments, and First Nations to support sustainable Indigenous-led businesses. The company has been selling scallops to several local businesses like restaurants and breweries.

A growing number of governments, companies, and nonprofit organizations are working together with new technology and data to identify fishing vessels that are breaking laws and engaging in human rights violations. Using satellite imagery and tracking signals, for example, a philanthropic company and a nonprofit worked with the UN Office on Drugs and Crime to help the Ghanian navy arrest four vessels for illegal fishing practices. Technology by itself won’t stop forced labor and unregulated ships, but it can be helpful for cash-strapped governments looking to increase oversight of their fisheries.

Beavers and the dams they build have been found to be tools against climate change as the planet’s temperature continues to rise. Dams slow water down and allow it to seep into the Earth, providing groundwater for humans, and also cools down both water and air temperatures. Beaver dams also create wetland ecosystems that are practically resistant to wildfires.

Two nonprofits came together to manage Hawai'i's Kaua‘i’s Hā‘ena State Park in a community-led way, creating a more equitable relationship between the tourism industry and the local community. Native Hawaiians work at the park, lead restoration projects and run educational programs. And to prevent overtourism, tourists must make reservations and pay to enter.

A locally-owned wood lot in Oakridge, Oregon, collects piles of debris from the surrounding forest that could become fuel for wildfires and turns it into firewood for the community. Alongside wildfire mitigation, the business reduces the air pollution residents create when their only option is to burn wet wood for heat.
