Mangrove forests are highly productive ecosystems that provide an invaluable service to humans. However, little information is available about the effects of urbanization on mangrove systems and their ability to sequester carbon.
To answer that question, scientists used NOAA C-CAP land cover data to identify developed areas, and areas covered by vegetation and open water. Other data sources pulled gave the team information on mangrove coverage, population density, and road density.
Compiling all of this information calculated a Mangrove Urban Index. From that, the team found that mangroves at the more highly urbanized location experienced higher emissions of carbon dioxide and methane from the soils and adjacent waters. These mangroves also had a higher magnitude of methane emissions in the adjacent waters than the soil.
