00. Ocean Decade - Philippines

Permanent URI for this communityhttps://repository.unesco.gov.ph/handle/123456789/7

The UNACOM Online and Digital Enabling Library and Index is developed to support the alignment of research, investments, and community initiatives toward contributing to a well-functioning, productive, resilient, sustainable, and inspiring ocean. The goal is to enable the government, partner agencies, and UNESCO to develop more robust Science-Informed Policies and facilitate a stronger Science-Policy Interface through the gathered data, information, and knowledge related to the Ocean Decade in the Philippines.

Particularly, it aims to:
  • Gather and index all publications, reports, policies, laws, legislations, articles, and other documents of the Philippine National Committee on Marine Sciences (NCMS) related to the Ocean Decade.
  • Disseminate and promote these publications, reports, policies, and other documents on the initiatives and actions to address the Ocean Decade challenges.

    Spatial planning insights for Philippine coral reef conservation using larval connectivity networks
    Pata, Patrick R.; Yñiguez, Aletta T. (Frontiers Media SA, 2021-10-06)
    The marine habitats of the Philippines are recognized to be some of the most biodiverse systems globally yet only 1.7% of its seas are designated as marine protected areas (MPAs) with varying levels of implementation. Many of these MPAs were established based on local-scale conservation and fisheries objectives without considering larger-scale ecological connections. The connectivity of reefs through larval dispersal is important in the regional-scale resilience against anthropogenic disturbances and is considered a significant criterion in planning for MPAs. In this study, we provide insights into the delineation of ecologically connected MPA networks using larval dispersal modeling and network analysis. We characterized the network properties of the Philippine coral reefs, organized as 252 reef nodes, based on the larval connectivity networks of a branching coral, sea urchin, and grouper. We then evaluated the distribution of the existing 1,060 MPAs relative to the connectivity patterns. All reef nodes were found to be highly interconnected with a mean shortest path ranging from 1.96 to 4.06. Reef nodes were then ranked according to their relative importance in regional connectivity based on five connectivity indices. Despite the between-organism and between-index variability in rankings, there were reefs nodes, mostly located offshore and at major straits, which consistently ranked high. We found that the distribution of existing MPAs partially capture some of the regional connectivity functions but there is a spatial mismatch between the primarily coastal MPAs and the high-ranking reef nodes. Furthermore, network partitioning identified subnetworks and dispersal barriers. The existing MPAs were found to be disproportionately distributed to a few subnetworks and that the largest subnetworks do not contain the greatest number of MPAs. Considering these gaps, we suggest expanding the coverage of protected areas especially in underrepresented reef networks to meaningfully capture national-scale connectivity and meet global conservation objectives.

    A review of the status of Philippine reefs
    Gomez, E. D.; Aliño, P. M.; Yap, H. T.; Licuanan, W. Y. (Elsevier BV, 1994-01)
    Since 1979, the status of Philippine reefs has been periodically updated. While conditions of the reefs during the early surveys were assessed in terms of live coral cover per se, the ‘coral mortality index’ was applied to the sets of data collected during the past 7 yr which may be a better gauge in determining the health of the reefs. Generally, most reefs surveyed are in fair condition. Major destructive factors described are sedimentation and siltation from coastal development and activities inland, illegal and destructive methods of fishing, and overfishing. If the reefs are to continue to provide for the present and future users, the ecological processes that render them productive must be maintained through integrated approaches of coastal area management.

    Institutional dimensions of coral reef restoration in the Philippines
    Matorres, Dane Erlo; Fabinyi, Michael; Horigue, Vera; Novilla, Carmela Therese; Baria-Rodriguez, Maria Vanessa (Elsevier, 2024)
    While the Philippines is mostly known for its experiences on marine protected areas, local governments and non-government organizations are increasingly using coral restoration with the aim of rehabilitating degraded reef areas. Since the establishment of artificial reefs in the 1970s, the application, techniques and corresponding policy directives for reef restoration have evolved over time, and restoration has recently generated significant interest and investments from donors and government agencies. As the Philippines does not have a policy framework to support effective and sustainable practices for the use of different coral restoration techniques, the increase and unregulated use of restoration may result in unintended consequences and pose potential challenges to coastal management. To address this gap, we conducted a review of existing coral restoration policies, programs and projects across the country, with a focus on social, economic and governance aspects. The study collated existing published literature and unpublished information on coral restoration in the country, and conducted key informant interviews. The results show that coral restoration continues to increase, and that existing guidelines on coral restoration are poorly implemented and not widely understood among practitioners. While coral restoration projects reported ecological benefits, socio-economic impacts are limited. The evidence supports the need to review existing policies and contextualize coral restoration to contribute to relevant policy decisions about the restoration and protection of reefs.
