Environmental Conservation Practices of Coastal Communities: Its Implications on the Sustainable Development of Mangrove Ecosystems

In the Philippines, with nearly 356,000 hectares of mangrove forests, deforestation and human pressures such as aquaculture, urbanization, and climate change threaten these ecosystems. This study examined the conservation practices of coastal communities in the Municipality of Dumangas and their impact on mangrove ecosystem sustainability. Using a descriptive-correlational design and purposive sampling, data were collected through questionnaires from 75 coastal community members. The top three conservation practices identified were supporting local mangrove laws, participating in preservation projects, and proper waste disposal in river and mangrove areas. Analysis by sex revealed that males prioritized preservation projects, waste management, and conservation laws, while females emphasized conservation laws, waste disposal, and prevention initiatives. Age analysis showed distinct focuses: respondents aged 40 and below prioritized preservation projects and waste management; individuals aged 41–60 focused on waste disposal, conservation laws, and eco-friendly practices; and those aged 61 and above emphasized preservation projects, conservation laws, and symposium participation. Across educational levels—elementary, high school, and bachelor’s degree—similar conservation priorities were observed. The study highlights the implications for mangrove sustainability, particularly in terms of coastal protection, biodiversity, and stakeholder engagement, and recognizes their economic significance for livelihoods and food security. A significant relationship between conservation practices and sustainable mangrove ecosystem development was identified. The study recommends further longitudinal research to evaluate the long-term effectiveness of mangrove conservation practices and management strategies.
