At dawn, fishermen cast their lines along quiet mangrove edges while birds skim the water in search of food. In the middle of concrete roads and crowded neighborhoods, these wetlands remain living pockets of nature that quietly protect Metro Manila every day.
On February 2, the Department of Environment and Natural Resources–National Capital Region (DENR-NCR) joined the international community in observing World Wetlands Day, calling attention to the critical role wetlands play in urban life. This year’s global theme, “Wetlands: Sacred. Life-sustaining. A Timeless Legacy. Ours to Protect,” highlights the shared responsibility of governments and citizens to preserve these fragile ecosystems.
Wetlands include mangroves, rivers, lakes, marshes, estuaries, and coastal areas. In Metro Manila, they serve as natural shields against floods, help clean water, store carbon, and provide habitat for fish, birds, and other wildlife. These benefits are especially important in a region that faces frequent flooding, rising temperatures, and the impacts of climate change.
DENR-NCR stressed that despite heavy urbanization, the capital region is still home to several important wetlands. These areas support food security by serving as breeding grounds for fish and other aquatic species, while also protecting nearby communities from storm surges and extreme rainfall. When wetlands are damaged or filled, floods worsen and water quality declines, affecting millions of residents.
To raise public awareness, DENR-NCR announced an information campaign featuring the “Top 10 Known Wetlands in NCR.” The campaign aims to educate the public about where these wetlands are located, why they matter, and how ordinary citizens can help protect them. Officials said knowledge is a key step toward conservation, especially for communities living near these areas.
According to environmental experts, wetlands act as natural sponges. They absorb excess rainwater during storms and slowly release it, reducing flood risks in low-lying areas. In Metro Manila, where drainage systems are often overwhelmed during heavy rains, healthy wetlands can make a real difference. Wetlands also trap pollutants and sediments, helping improve water quality in rivers and coastal zones.
The DENR noted that wetlands are also deeply connected to Filipino culture and livelihoods. Many coastal and riverside communities depend on them for fishing, small-scale aquaculture, and eco-tourism. For these families, protecting wetlands is not just an environmental issue but an economic one.
However, wetlands remain under threat from land reclamation, illegal dumping, pollution, and unchecked development. Climate change adds further pressure through sea level rise and stronger storms. DENR-NCR warned that once wetlands are destroyed, they are difficult and costly to restore.
As part of World Wetlands Day, the agency called on local governments, schools, businesses, and residents to take part in conservation efforts. Simple actions such as proper waste disposal, reporting illegal activities, supporting clean-up drives, and respecting protected zones can help preserve these ecosystems.
DENR-NCR also emphasized the need for long-term planning that balances development with environmental protection. Sustainable urban growth, officials said, must recognize wetlands as vital infrastructure, just as important as roads, bridges, and buildings.
As Metro Manila continues to grow, the message of World Wetlands Day is clear. Wetlands may often be overlooked, but they quietly sustain life, protect communities, and support the city’s future. Safeguarding them today ensures that the next generation inherits a safer, healthier, and more resilient urban environment.
