The University of the Philippines Institute of Biology advocated for the planting of mangroves in Manila Bay instead of crushed dolomite, in an effort to provide solutions to the area’s environmental issues.
Planting mangroves, the institute said, was a both a nature-based and cheaper solution which has, as shown in a similar mangrove area—the Las Piñas-Parañaque Critical Habitat Ecotourism Area (LPPCHEA)—contributed substantially to biodiversity conservation and climate change adaptation.
The body added that the Manila Bay “white sand” project missed the mark in terms of rehabilitation with its use of dolomite, which produces a detrimental effect to the existing biodiversity and surrounding communities.
They offered to assist the Department of Environment and Natural Resources (DENR) in implementing a “science-based rehabilitation program” aimed at recovering the body of water’s biological functions and is based on the interaction between human activity and natural processes.
The institute also said that a proper rehabilitation program should exhibit some understanding of land-sea connectivity and immediate, short-term and long-term effects on the ecosystem.
