With over 7,600 islands and around 2.2 million square kilometers of marine territory, Philippine waters boast rich marine biodiversity that sustains local fisheries while contributing to global ecological health. These ecosystems are vital in regulating the climate and maintaining environmental stability.

Particularly noteworthy are seagrass beds and coral reefs, which are important for both oceanic health and the livelihoods of coastal communities. These habitats offer critical ecosystem services: they serve as fish breeding grounds, protect shorelines from erosion and sequester carbon emissions, assisting in the fight against climate change. The intricate beauty and ecological significance of these underwater ecosystems demand our attention and protection.

Building on the achievements of the 2024 Citizen Science for Mangrove Mapping Initiative, the Department of Environment and Natural Resources (DENR) is set to expand geospatial mapping efforts to encompass these essential coastal ecosystems. In collaboration with the Philippine Space Agency (PhilSA), this initiative presents a unique opportunity for citizens to engage in the protection of our marine resources.

Unlike the mapping of mangroves, the identification and mapping of seagrass and coral ecosystems require advanced technical expertise and resources. Thus, collaboration across various sectors is critical. At the initiative’s launch on 14 March, a coalition of stakeholders, including DENR, PhilsA, academic institutions such as the University of the Philippines and Ateneo, various NGOs and private sector entities like Metro Pacific Investment Corporation and the Ayala Foundation, came together. This united effort emphasizes the shared responsibility to safeguard our oceans.

Twenty priority sites have been earmarked for data gathering: Santa Ana, Maconacon-Divilican-Palanan, Bolinao, Masinloc, Calatagan, Apo Reef, Coron, El Nido, Honda Bay, Tubbataha Reef, Nogas Island, Sorsogon, Carles, Eastern Samar, Guiuan, Danajon Bank, Sta. Cruz Island, Tawi-Tawi and Davao Gulf.

Opportunities for involvement include data sharing, field validation activities, capacity training, underwater image classification and financial support. Whether you have technical skills, a passion for marine conservation, are a researcher, a diver, or simply wish to dedicate your time, there is a role for everyone in this essential effort.

Validation methods for assessing seagrass and coral ecosystems will incorporate the ODK (Open Data Kit) app, a set of tools designed for field data management and analysis, widely used across various sectors such as health and agriculture. Volunteers will also engage in methods like towed video and snorkeling with underwater cameras, submitting shapefiles or GPS coordinates for analysis. The findings from these efforts will undergo processing using the Automated Rapid Reef Assessment System, developed by Dr. Maricor N. Soriano from the University of the Philippines-National Institute of Physics, ensuring valuable and actionable insights.

Our oceans represent a fundamental aspect of Filipino identity. By valuing and protecting these waters, we reaffirm our commitment to cherish and celebrate this vital national resource.
