Ocean acidiification can trigger algal bloom

THE ALLURING BEAUTY OF BORACAY. Local and foreign tourists frolic in the white sands of the famous Boracay beach while others could not resist but to swim in the waters unmindful of the presence of the green-algae that abounds from end to end. The water along the long beach remains safe for swimming based on the result of water sampling conducted by the DENR-EMB. As observed, the green algae occurs during the months of February to June and will eventually disappear starting the month of September bringing back to its natural beauty of being the best tropical white beach in the world.


Global warming has a significant impact on our marine ecosystem. The continued rise of carbon dioxide presence in the atmosphere triggers ocean acidification which augments the growth of diatoms and algae. 

Yoshihisa Shirayama, Executive Director for Research of Japan Agency for Marine-Earth Science and Technology made the presentation during the Asia Pacific Economic Conference (APEC) Meeting at the Crown Regency Hotel and Convention Center on May 9.

Boracay Island is hosting several high-profile meetings from May 9 to 24. The series of meetings include topics concerning tourism, environment, and marine and coastal protection, among others.

In his report, Shirayama shared that high carbon dioxide presence in the atmosphere resulted to ocean acidification hugely affecting marine ecosystem – one of which is the occurrence of algae in shores.

The algal bloom in Boracay Island can be attributed to this phenomenon, though it could not be discounted that it may have triggered by poor waste management from resorts, other business establishments and residents in the island.

According to Shirayama, those directly affected (which he referred to as “losers”) are shells, snails, abalones, clams, oysters, scallops, sea urchins, sea stars, brittle stars, calcareous phytoplankton, and reef building corals. The report added that the “maybe losers” are fishes, shrimps, and crabs; and, the “winners” are algae, sea grasses, diatoms and soft corals.

Prior to this, Sampulna had already instructed all field offices in the region with coastal areas to immediately report presence of green algae, if there are any, considering that this is a global phenomenon.

Green algae are also observed in other areas in the region, he said.

Earlier, DENR Secretary Ramon JP Paje has ordered to conduct an inventory of resorts and other commercial establishments to check on their compliance to the environmental rules and laws, particularly on waste water management.

Resort owners, business operators and residents in the island, however, maintained that the algal bloom in the famous white beach is seasonal and a natural occurrence during the summer season mainly during the months of February to June, and eventually disappear starting September.

In celebration of World Wetlands Day, the Department of Environment and Natural Resources (DENR) 6 through its Conservation and Development Division (CDD) conducted a Bird Watching Activity in Barangay Tubigan, Zarraga, Iloilo last February 02, 2019.

The DENR CDD prepared the needed equipment including binoculars and telescopes for the students of Zarraga National High School to closely spot the birds. The students enjoyed the environment and were amazed seeing hosts of different species of migratory birds hovering and wading along the area.

Migratory birds sighted in the area were Black winged-stilt, Egrets, Heron and Moorhen.

After the Bird Watching Activity, the CDD team conducted a lecturette on climate change and the importance of wetlands. It was followed by a Poster and Slogan Making contest among students to showcase their creativity and skills. Also, an Environmental Photo exhibit was installed by the Regional Public Affairs Office (RPAO) for the students, showcasing climate change and birds found in wetlands.

“Wetlands and Climate Chang’ is the theme of the World Wetlands Day 2019. The theme demonstrate the important of wetlands  to mitigate the impacts of climate change and have a sustainable environment. It also has a sub-theme which states: “We are not powerless against climate change. Stop Draining Wetlands.

The activities aim to teach the youth to protect and appreciate wetlands in our ecosystem as they play a critical part in our natural environment for protecting our shores, reducing of floods, absorbing pollutants, improving water quality and serving as habitat for animals.

The Regional Executive Director (RED) Francisco E. Milla Jr. was happy to note that the birds seen in Brgy. Tubigan signify that there are abundant food and a comfortable climate for the migratory birds. Moreover, the DENR is hoping to continuously maintain our wetlands ecosystem for its valuable contribution in fighting the effects of climate change.

Scaling-up of coastal and marine ecosystem and clean water project are anchored on the ten (10) priority programs of DENR Secretary Roy A. Cimatu.
