Philippine Marine Scientists Oppose Dumaguete Reclamation


The Philippine Association of Marine Science (PAMS), composed of more than 200 members from  over 45 leading Philippine and overseas universities, government agencies, and non-government  organizations, joins the collective voice of civil society in strongly objecting to the 174 hectare  (approximately 7 km long) reclamation project in Dumaguete City pushed by the local government.


  1. It will bury very large areas of productive coral reefs and seagrass beds (45-67 hectares or more),  which will endanger the food security and livelihoods of more than 900 local fisherfolk and their  families. Claims have been made that these ecosystems can be “rebuilt” elsewhere to mitigate  the damage. However, they cannot be restored by simply relocating corals, creating artificial  reefs, or replanting seagrass because scientifically sound and cost-effective ecosystem restoration  technologies at such massive scales are still poorly developed. 

  2. It will directly or indirectly impact the rich biodiversity of the region. The waters of Dumaguete host at least 150 species of corals, 200 species of fish, including sharks and rays, nine species of seagrass,  and 20 species of mangroves. Endangered, threatened, and/or protected species under  international or Philippine laws also inhabit or use these waters, including giant clams and other  marine invertebrates, whale sharks, marine turtles, and the blue whale – the largest animal on  Earth. 

  3. Four marine protected areas (MPAs) that the city legally established from 2001 to 2014, which serve  as spawning grounds for fish that live on coral reefs and seagrass beds, will simply cease to exist.  This will weaken the interconnected network of MPAs in the region, including the Apo Island  Protected Landscape and Seascape. Under the Environmental Impact Assessment process, all MPAs  – both national and local – should already be classified as an Environmentally Critical Areas.  Converting the MPAs in Dumaguete into reclaimed land violates national laws and contradicts  local and national government mandates to promote and sustain networks of MPAs as a means  to conserve marine biodiversity and manage fisheries. 

  1. It will further result in irreversible negative impacts to the surrounding environment. The massive  project will require enormous amounts of filling material sourced from the seafloor by dredging or  from land by quarrying. High sediment suspension and dispersal by currents will very likely affect  neighboring areas, including the nearby Tañon Strait Protected Seascape. 

  2. It will likely impede the natural flow of water from the rivers and streams of Mt. Talinis. This may  worsen flooding in the coastal barangays of Dumaguete, home to approximately 38,000 residents. 

We strongly urge the local government unit of Dumaguete City to reconsider this project seriously. We  also urge the neighboring LGUs to voice out their concerns, as this reclamation project will also affect  them. The damage to the environment will be enormous and irreversible. We call on the Philippine  Reclamation Authority, the Department of Environment and Natural Resources, and the Department of  Interior and Local Government to treat this project with utmost scrutiny and to ensure that the people  of Dumaguete City are duly consulted and informed at all times during the long and careful process of  assessing the environmental and socio-economic impacts of this project, as required by Philippine laws. 

Adopted on the 24th July 2021, during the 16th National Symposium on Marine Science, Philippines. oOo

    […] In response to perceived greenwashing by Remollo, Juntereal told the authors in an interview on September 21, 2021, that citizens began work on a community campaign to prove that Dumaguete—contrary to the mayor’s claim—does have coral reefs. Marine scientists joined the campaign to decry their exclusion from the consultation and decision-making process. The scientists pointed out that the project could “bury very large areas of productive coral reefs and seagrass beds.”5 […]
