Sand Mining Hurts Filipino Beaches

In Zambales, a province known for its surf breaks and beachfront resorts, a different kind of wave is washing away the coastline. A devastating erosion event in San Felipe has displaced families and destroyed over 30 beachfront establishments, with damage now linked to massive dredging vessels operating under the guise of flood control. For the communities that depend on these shores, this is not a natural disaster — it is a man-made one, driven by a policy that prioritizes reclamation sand for Metro Manila projects over the health of local ecosystems.

These figures come from a Preliminary Damage Assessment Report by the San Felipe Resort Owners Association, covering the impact of two typhoons and three low-pressure areas over eight days. But the root cause, according to environmental groups and local residents, is not the weather — it is the systematic extraction of sand from the seabed and river deltas. The practice, enabled by DENR Administrative Order No. 13, series of 2019, authorizes widespread desilting of Zambales’ rivers — Bucao, Sto. Tomas, San Felipe, and San Marcelino — as a flood control project. Locals argue that Zambales is not a flood-prone province, as its natural drainage is the West Philippine Sea, making the dredging both unnecessary and dangerous. For a deeper look at how policy failures compound environmental damage, see our article on the Philippines’ broader ecological challenges.

What Sand Mining Does to a Coastline

The core mechanism is straightforward but often misunderstood. Sand mining — whether from riverbeds or the seabed — creates what environmental experts call a

Philip Camara, Chairperson of the Institute of Area Management, explains that “massive dredging of the seabed and the river delta creates a sediment deficit that interrupts the longshore drift responsible for replenishing our coastline.” In plain terms: take too much sand from the system, and the beach has no way to rebuild itself. The result is not gradual erosion but sudden, catastrophic loss — exactly what San Felipe experienced.

The Policy That Enabled the Crisis

At the center of this controversy is DENR Administrative Order No. 13, series of 2019, which authorized the desilting of Zambales’ rivers as a flood control measure. Environmental groups, including the Zambales Ecological Network (ZEN), argue that the order is a cover for extracting reclamation sand destined for Metro Manila projects like the Pasay Harbor Reclamation. The Philippine Misereor and Partnership Inc. (PMPI) has stated that these operations, “disguised as development, are a direct violation of the people’s right to a healthy environment and sustainable livelihood.”

The local government’s response has been measured. The Mines and Geosciences Bureau (MGB) has stated that dredging in Barangay Liwliwa did not cause the coastal erosion, while provincial leaders have said they will consult experts before determining the proper course of action. For communities already displaced, this pace feels inadequate. Hai Fernandez, Executive Director of ZEN, warned: “If Governor Ebdane does not halt his sand mining activities, the entire coastline of San Felipe, San Narciso, Cabangan, and Botolan will disappear.” The situation echoes other environmental conflicts in the country, such as the fight against deforestation and pollution, where short-term economic interests clash with long-term ecological stability.

What Gets Overlooked in the Sand Mining Debate

The Disruption of Natural Sediment Flow

Most discussions about sand mining focus on the visible damage — the eroding beach, the collapsing road. What gets less attention is the invisible mechanism: the longshore drift. This is the natural current that moves sand along the coast, replenishing beaches and maintaining the shoreline. When dredging removes massive volumes of sand from the seabed or river delta, it creates a deficit that the current cannot fill. The result is not just local erosion but a cascading effect that can impact coastlines kilometers away. As one resident of Barangay Sindol described it, the ₱100 million coastal road built by the DPWH “disappeared like it never existed” after six months of sand extraction by Chinese dredging vessels.

The Foreign Vessel Dimension

Reports indicate that Chinese vessels have been involved in extracting sand from Zambales’ shores. PMPI has stated that these operations generate “massive revenues for provincial governments and foreign companies.” This raises questions about who benefits from the extraction and who bears the cost. The sand is reportedly destined for reclamation projects in Metro Manila, meaning the environmental damage is exported to one province while the economic benefits flow elsewhere. This dynamic is not unique to sand mining — similar patterns appear in overfishing and pollution in Filipino seas, where local communities bear the brunt of resource extraction driven by external demand.

The Rights of Nature Argument

Environmental groups are increasingly framing the issue not just as a matter of policy failure but as a violation of the rights of nature itself. PMPI’s statement explicitly calls the dredging “an affront to the rights of nature,” a legal and philosophical position that recognizes ecosystems as having inherent rights to exist, thrive, and regenerate. While this argument has gained traction in some legal systems, it remains a minority view in Philippine jurisprudence. However, it reflects a growing frustration with the limits of existing environmental regulations, which groups like ZEN argue have been “enabling destructive projects under the guise of flood control.”

What Can Be Done: A Practical Guide for Communities and Advocates

Demand a Repeal of DENR Administrative Order No. 13

ZEN and allied groups are calling on the Marcos administration to repeal DAO 13, series of 2019, and replace it with a “scientific, transparent, and community-led sediment management plan.” The key difference is where the management happens: upstream near the Mt. Pinatubo crater, where volcanic sediments naturally accumulate, rather than along fragile coastlines. For advocates, the first step is to understand the legal basis of the current order and to push for its replacement through local government resolutions, public consultations, and direct appeals to the DENR and the Office of the President.

Support the Presidential Directive on Flood Control Contracts

President Ferdinand Marcos Jr. has issued a directive to review immediately all flood-related contracts, especially those under the Department of Public Works and Highways (DPWH). Communities and advocates can use this directive as leverage to demand transparency in how dredging contracts are awarded and monitored. The directive provides a window of opportunity to question whether projects labeled as “flood control” are actually serving that purpose or are being used to extract sand for reclamation. Local governments can submit formal requests for contract reviews and public audits.

Build a Community-Led Monitoring System

One of the gaps exposed by the Zambales crisis is the lack of independent, community-based monitoring of dredging operations. Residents and resort owners were the first to notice the cracking coastal road and the retreating shoreline, but their observations were not immediately acted upon. A formal monitoring system — where trained community members document shoreline changes, water quality, and vessel activity — can provide the evidence needed to trigger government action. This approach has been used successfully in other environmental conflicts, such as fighting industrial pollution through community action.

• 1
  Organize a Community Watch

  Form a local group to document shoreline changes, photograph dredging vessels, and record water quality observations. Use smartphones and simple measuring tools.

• 2
  Submit Reports to the MGB and DENR

  File formal complaints with photographic evidence. Request official responses in writing. Keep copies of all correspondence.

• 3
  Engage Media and Advocacy Networks

  Share documented evidence with environmental journalists and organizations like ZEN and PMPI to amplify the call for action.

Push for an Upstream Sediment Management Plan

The alternative proposed by ZEN is to manage sediment where it originates — near the Mt. Pinatubo crater. Volcanic eruptions and natural erosion deposit massive amounts of sand and gravel in upstream areas. Harvesting these materials before they reach the coast could provide a sustainable source of construction sand without destroying beaches. This approach requires coordination between the DENR, DPWH, local governments, and communities, but it offers a path that does not sacrifice one province’s coastline for another’s reclamation project.

Frequently Asked Questions About Sand Mining in Zambales

What Happens Next

The Zambales coastline is not just a scenic backdrop — it is the economic and cultural foundation for thousands of families. The choice facing policymakers is not between development and the environment, but between two kinds of development: one that extracts resources for short-term profit elsewhere, and one that sustains the communities that live there. The call from ZEN and allied groups is clear: repeal DAO 13, replace it with a science-based sediment management plan, and hold accountable those who have enabled the destruction. The alternative, as Fernandez warned, is that “Zambales will become a cautionary tale of environmental collapse enabled by failed policy.” If this was useful, you might also want to read how rising acidity is affecting Filipino seas.
