Xavier Ateneo - McKeough Marine Center (MMC) participated at the 51st annual convention of the Federation of Institutions for Marine and Freshwater Sciences (FIMFS) held at the Southern Leyte State University (SLSU) from October 16 to 18.

The study was presented by Chev Duay (XU Marine Biology alumnus, 2017), MMC research assistant, with co-author of the study was Elaine Villlaluz, XU Marine Biology faculty. 

The other authors of the study, Rad Edulan (XU Marine Biology alumnus, 2017), MMC research assistant and Fr Mars Tan SJ, project leader, were not able to join the convention.  

The study presented used field data collected in the mangrove mapping in the Macajalar Bay Project of the XU-MMC and the Forest Foundation Philippines. 

The study titled, “Biomass, Carbon Stock, and Community Structure of Mangroves in Macajalar Bay” was conducted to estimate the amount of atmospheric carbon dioxide absorbed and then stored inside the biomass of mangrove trees in the form of leaves, branches, roots, and stems. The carbon sequestered and stored in mangroves is called "blue carbon."

The results showed that the mangroves in Macajalar Bay (20 different species) which cover a total of 170 hectares have stored an estimated 99,161.17 tons of organic carbon. 

This total amount of organic carbon stored in Macajalar Bay mangroves is equivalent to the annual carbon footprint of 75,696 people (fossil CO2 emissions) or the yearly CO2 emission of 21,500 passenger vehicles.  

A typical passenger vehicle emits about 4.6 metric tons of carbon dioxide per year (US Environmental Protection Agency).

The study will provide vital information to mangrove forest managers, planners, planters and the like to boost and encourage the planting of mangroves as a strategy to help mitigate climate change.
