Inspiring MD Pride: Faculty Helps Develop Method to Encourage Worldwide Wetlands Restoration
A team of scientists, including Associate Professor Brian Needelman from the University of Maryland’s Department">http://www.enst.umd.edu/">Department of Environmental Science and Technology, has developed a method for measuring the removal of greenhouse gases from the atmosphere achieved through coastal wetland restoration. The methodology, approved Tuesday, November 24th by the Verified">http://www.v-c-s.org/">Verified Carbon Standard, will make it possible for these types of environmentally beneficial restoration projects to receive funding around the world.
Coastal wetlands – which include salt marsh, seagrass, mangroves and other tidal wetlands – are some of the most productive habitats in the world. In addition to providing critical fish habitat, improving water quality, and protecting the coastline from storms, coastal wetlands also remove large amounts of carbon dioxide from the atmosphere through photosynthesis. This carbon (referred to as “blue">http://www.estuaries.org/bluecarbon">blue carbon”) is then stored in the ground, where it can remain for centuries or more, as long as the habitat is not degraded or destroyed.
However, development pressures, polluted runoff and sea-level rise has caused the loss of 50% of U.S. wetlands since the 1800s. Globally, coastal wetland loss is estimated to be between 0.7-7% a year, and restoration projects are largely underfunded, despite the myriad of benefits these habitats provide. As coastal habitat is destroyed, the carbon stored in its soil may be emitted back into the atmosphere, contributing to global climate change.
This landmark methodology provides the procedures for how to calculate, report, and verify greenhouse gas reductions for tidal wetland restoration projects globally. Now, projects such as removing tidal barriers, improving water quality to increase seagrass habitat, beneficial use of dredged material, and reintroducing native plant communities will be eligible to earn carbon credits on the voluntary carbon market, generating new sources of funding.
“I’ve spent a lot of time with coastal wetlands. I love them. They provide so many ecosystem services and are just beautiful ecosystems themselves,” says Needelman, PhD, who has spent a decade researching coastal wetlands and the last four helping to develop the methodology. “Unfortunately, coastal wetlands are vanishing globally at unprecedented rates. This methodology is one way we can help people who want to do something to reverse this trend by giving them a tool that will make securing funding easier.”
Carbon credits are purchased by companies or individuals to offset the emissions they can’t reduce. Thanks to this new methodology, companies can purchase carbon credits to support coastal habitat projects that provide a climate benefit.
