Abstract:

 

In the context of climate change and global warming, carbon sequestration receives a considerable attention now. In the latest assessment report of the Intergovernmental Panel on Climate Change (IPCC), global mean temperature has dramatically increased over the past decades. There is also mounting evidence that this increase will remain as problems on landuse change and industrial emissions continue to worsen. Among the GHGs, CO2 is the most abundant. Forest ecosystems such as mangroves play a significant role in the climate change problem because they serve as sinks of atmospheric. Great attention is focused on tropical forests to offset carbon emissions. Thus, this study was intended to assess the carbon storage potential of a mangrove forest in San Juan Batangas. A nested plot method developed by ICRAF-ASB Program and allometric equations developed by Komiyama et.al. (2005) were employed to estimate the above-ground biomass and carbon density of the two stands: Rhizophora-dominated stand in Barangay Poctol; and Avicennia-dominated stand in Barangay Catmon. Both Rhizophora and Avicennia dominated stand exhibited good carbon storage potential hence proper forest management is essential to sustain and improve its capacity to help mitigate climate change.
