Blue Carbon, which is carbon captured by marine organisms, has recently come into focus as an important factor for climate change initiatives. This carbon is stored in vegetated coastal ecosystems, specifically mangrove forests, seagrass beds and salt marshes. The recognition of the C sequestration value of vegetated coastal ecosystems provides a strong argument for their protection and restoration. Therefore, it is necessary to improve scientific understanding of the mechanisms that stock control C in these ecosystems. However, the contribution of Blue Carbon sequestration to atmospheric CO2 in shallow waters is as yet unclear, since investigations and analysis technology are ongoing. In this study, Blue Carbon sinks by Zostera marina were evaluated in artificial (Gotenba) and natural (Matsunase) Zostera beds in Ise Bay, Japan. 12-hour continuous in situ photosynthesis and oxygen consumption measurements were performed in both areas by using chambers in light and dark conditions. The production and dead amount of Zostera marina shoots were estimated by standing stock measurements every month. It is estimated that the amount of carbon storage as Blue Carbon was 237g-C/m2/year and 197g-C/m2/year in the artificial and natural Zostera marina beds, respectively. These results indicated that Zostera marina plays a role towards sinking Blue Carbon.

Factors Affecting

Blue carbon ecosystem (BCE) initiatives in the Coral Triangle Region (CTR) are increasing due to their amplified recognition in mitigating global climate change. Although transdisciplinary approaches in the “blue carbon” discourse and collaborative actions are gaining momentum in the international and national arenas, more work is still needed at the local level. The study pursues how BCE initiatives permeate through the local communities in the Philippines and Indonesia, as part of CTR. Using perception surveys, the coastal residents from Busuanga, Philippines, and Karimunjawa, Indonesia were interviewed on their awareness, utilization, perceived threats, and management strategies for BCEs. Potential factors affecting residents’ perceptions were explored using multivariate regression and correlation analyses. Also, a comparative analysis was done to determine distinctions and commonalities in perceptions as influenced by site-specific scenarios. Results show that, despite respondents presenting relatively high awareness of BCE services, levels of utilization are low with 42.9–92.9% and 23.4–85.1% respondents in Busuanga and Karimunjawa, respectively, not directly utilizing BCE resources. Regression analysis showed that respondents’ occupation significantly influenced their utilization rate and observed opposite correlations in Busuanga (positive) and Karimunjawa (negative). Perceived threats are found to be driven by personal experiences—occurrence of natural disasters in Busuanga whereas discerned anthropogenic activities (i.e., land-use conversion) in Karimunjawa. Meanwhile, recognized management strategies are influenced by the strong presence of relevant agencies like non-government and people’s organizations in Busuanga and the local government in Karimunjawa. These results can be translated as useful metrics in contextualizing and/or enhancing BCE management plans specifically in strategizing advocacy campaigns and engagement of local stakeholders across the CTR.

Atmospheric Carbon

The blue carbon paradigm has evolved in recognition of the high carbon storage and sequestration potential of mangrove, saltmarsh and seagrass ecosystems. However, fluxes of the potent greenhouse gases CH 4 and N 2 O, and lateral export of carbon are often overlooked within the blue carbon framework. Here, we show that the export of dissolved inorganic carbon (DIC) and alkalinity is approximately 1.7 times higher than burial as a long-term carbon sink in a subtropical mangrove system. Fluxes of methane offset burial by approximately 6%, while the nitrous oxide sink was approximately 0.5% of burial. Export of dissolved organic carbon and particulate organic carbon to the coastal zone is also significant and combined may account for an atmospheric carbon sink similar to burial. Our results indicate that the export of DIC and alkalinity results in a long-term atmospheric carbon sink and should be incorporated into the blue carbon paradigm when assessing the role of these habitats in sequestering carbon and mitigating climate change.

And Function

Mangrove forests are one of the vital ecosystem components for coastal areas. Therefore, conservation efforts are required for mangrove forests to prevent damage to the broader mangrove forests. The study of local communities through a perception and participation approach was conducted to identify the problem of mangrove forests damage. Aspects of community perception play an essential role in the formulation of mangrove forest management to ensure the sustainability of mangrove forests and maintain community welfare. The survey was conducted from September to December 2017. Respondents in this study are fishers and fish farmers in Muara Pantuan village, Anggana Sub-district, Kutai Kartanegara Regency whom their occupation directly related to the utilization of mangrove forests. Results showed that about 50% of respondents recognized the existence and function of mangrove forests. 15% of respondents did not know about the rules of mangrove forests. Even 30% of them very did not recognize. Regarding law enforcement, 43% of respondents did not know about the law enforcement of mangrove forests although almost 85% of them stated that the regulation of sustainable mangrove forests was required. Furthermore, for the participation of the community, about 57% of respondents were actively involved in the conservation of mangrove forests.Hutan mangrove adalah salah satu komponen ekosistem penting bagi kawasan pesisir. Dalam rangka mencegah kerusakan hutan mangrove yang lebih luas lagi maka perlu upaya pelestarian terhadap hutan mangrove yang masih tersisa melalui pendekatan persepsi dan partisipasi melalui kajian masyarakat lokal. Hal ini penting mengingat aspek persepsi masyarakat memegang peranan penting dalam perumusan pengelolaan hutan mangrove agar sumberdaya tersebut dapat dipertahankan dan ditingkatkan sehingga dapat menjamin keleslarian dan kepentingan sosial ekonomi masyarakat sekitarnya. Tujuan penelitian adalah untuk mengetahui persepsi serta tingkat partisipasi masyarakat dalam pelestarian hutan mangrove di Desa Muara Pantuan Kecamatan Anggana Kabupaten Kutai Kartanegara. Kegiatan penelitian di lapangan dilakukan selama 2 (dua ) bulan dari bulan September 2017 sampai dengan Desember 2017. Populasi dalam penelitian adalah masyarakat yang terkait langsung dengan pemanfaatan hutan mangrove yaitu nelayan dan petambak. Persepsi masyarakat Desa Muara Pantuan Kecamatan Anggana mengenai hutan mangrove dimana 50% mengetahui keberadaan dan fungsi hutan mangrove. Tetapi masyarakat tidak mengetahui mengenai peraturan hutan mangrove sebesar 15%, bahkan 30% sangat tidak mengerti atau sangat tidak memahami mengenai peraturan hutan mangrove. Demikian pula mengenai sangsi dimana 43% menyatakan tidak tahu mengenai sanksi pemanfaatan hutan mangrove, Namun demikian 85% responden menyatakan perlunya peraturan untuk pelestarian hutan mangrove. Kemudian tingkat partisipasi masyarakat dalam pelestarian hutan mangrove di Desa Muara Pantuan adalah sebesar 57%, yang berarti bahwa masyarakat sudah cukup aktif untuk mendukung pelestarian hutan mangrove.

ABSTRACTThis research aimed to investigate the Willingness to Pay (WTP) for mangroveconservation of local communities at Salut Mengkabong Lagoon, Tuaran based on theamount of fees imposed on them. The content is based on questionnaire survey providedto local communities from Mangrove Forest Produce (MFP) to their perception inconservation programme. The survey was conducted with a priod of 7 month startedfrom September 2016 until March 2017. Contingent Valuation Method (CVM) was usedto calculate the Willingness to Pay (WTP) whereby 100 respondents were asked tocomplete the questionnaire. From the analysis, it showed that the WTP of localcommunities were affected by their monthly income. Regression model analysis withWTP = -0.087* (monthly income) + 1.789 has been formed. Whereas, the value ofmangrove forest produce (MFP) in Salut Mengkabong Lagoon has been calculated with atotal of RM728 for the direct product while for the non-direct products such as crab,bivalves, seashells and fishes cost about RM721 to RM2472 in a year. The studydocumented mangrove forest contribution to local communities in Salut MengkabongLagoon such as timber; Rhizophora mucronata and Avicennia spp, Seafood; Scyllaserrata, Geloina coaxans, various type of fishes and seashell. From the result, it washope that this study can promote a win-win situation to both local community andstakeholders to come out with an effective supervision to ensure the long-lastingdependency of local communities to the mangrove forests without undermining theirsocio-economic wellbeing.Keywords: Salut Mengkabong Lagoon, Mangroves Forest Produce, local community
