DENR chief pushes mangrove conservation

The Department of Environment and Natural Resources (DENR) is pushing for the conservation of wetlands and mangroves in Bataan, citing their role in reducing flood risks, protecting coastal communities and sustaining the livelihoods of local fisherfolk.

During his visit to the Balanga Wetland and Nature Park in Bataan on 29 October, DENR Secretary Mitch Cuna highlighted how healthy wetland ecosystems serve as natural defenses against flooding while providing habitats that support fisheries.

Cuna said the initiative is in line with President Ferdinand Marcos Jr.’s directive to strengthen disaster preparedness and environmental protection.

He added that the DENR is advancing nature-based solutions to reduce flood risks, protect fisheries and sustain the livelihoods of communities that depend on coastal resources.

“Today, healthy wetlands and mangroves serve as natural defenses against flooding in the surrounding communities, provide habitats that support fisheries, and help sustain the livelihoods of local fisherfolk,” Cuna said.

During the visit, Cuna saw how healthy mangroves at the Balanga Wetland and Nature Park serve as a natural shield for residents of Barangay Tortugas.

Wetland ecosystems, particularly mangrove forests, help protect coastal communities by slowing storm surges, absorbing excess water and reducing wave energy before it reaches populated areas.

The dense vegetation, sturdy trunks and complex aerial root systems of mangroves create friction that helps dissipate the force of incoming waves. The source report said healthy mangrove forests can absorb as much as 70 to 90 percent of wave energy during intense storms.

Mangroves also help stabilize shorelines. Their intricate root systems trap sediment and gradually build up the coastal soil bed, helping protect communities against erosion.

The first 100 meters of a healthy mangrove forest can reduce wave energy by as much as 66 percent, according to the information provided in the report.
