Carbon stock of mangrove ecosystem and role blue economy in Pangandaran West Java

Abstract

The mangrove ecosystem is a forest area that grows in coastal areas and is located at a distance of 200 meters from the shoreline. Mangroves are one of the blue-carbon ecosystems that can absorb CO2 through the process of photosynthesis and store carbon in the form of biomass in the soil. Mangroves are the second largest store of carbon stocks in waters after coral reefs. The availability of mangrove ecosystem carbon stock data is very important as a baseline in the greenhouse data inventory from blue carbon ecosystems. Blue carbon can be used as a reference for the welfare of coastal communities commonly called the blue economy, the blue economy focuses on generating economic growth from the fisheries and marine sector in Indonesia. Marine ecosystems are also impacted by climate change. Based on data from WWF's Living Blue Planet Report 2015, the number of marine populations decreased by 49% in the period 1970- 2012. The data is closely related to the sustainable economic growth of the marine fisheries sector, in this case, the mangrove ecosystem. Analysis of mangrove ecosystems using circle plots carried out measurements of tree diameter and length and identification of tree species according to predetermined subplots then analyzed the amount of carbon stock using the Allometric Equation Model. The result obtained is that 80% of mangrove habitat conditions are still very good so they can contribute to producing a total stored carbon stock (blue carbon) of 55.98 tons/ha this can be an ecosystem service for the surrounding community that can increase the blue economy in the Pangandaran area of West Java.
