Mining Hurts Filipino Rivers and Seas

The Philippines sits on some of the world’s largest nickel reserves, a mineral now in high demand for electric vehicle batteries and clean energy infrastructure. These laterite deposits account for roughly 70 percent of the world’s nickel reserves, making the country a critical node in the global energy transition. But for communities living near mining operations, the cost of that transition is measured in lost fish, sick children, and flooded homes.

These numbers frame a tension that is hard to ignore. The Philippines is the world’s leading exporter of raw nickel ore, and global demand is expected to rise roughly 60 percent by 2040 under climate-aligned scenarios. Yet the same mining activity that feeds the clean energy supply chain is also damaging the rivers, coasts, and forests that millions of Filipinos depend on for food and shelter. Understanding how this plays out on the ground — and who bears the burden — matters far beyond the mining towns themselves. For a closer look at how pollution affects different communities, you can read about pollution’s unequal impact on Filipino communities.

What Mining Expansion Means for Ecosystems and Livelihoods

The core issue is straightforward: mining operations, particularly for nickel laterite, are concentrated in areas that also hold high ecological and agricultural value. Palawan, often called the country’s last ecological frontier, is a case in point. Environmental groups estimate it may hold close to half of all the Philippines’ remaining untouched, old-growth forest, as well as 30 percent of its remaining mangroves and up to 40 percent of its coral reefs. Yet the island hosts 11 established, active mining projects that were exempted from a 2025 moratorium on mining expansion.

What makes this more than an environmental story is the direct impact on people’s daily lives. Fishermen in Brooke’s Point, Palawan, describe a clear timeline: fish began disappearing from the bay about four years ago, shortly after the mine expanded and shipped out its first 50,000 tonnes of nickel ore to China. A good day once brought in 40 kilograms of fish; now the catch is often as little as 7 kilograms. Rice yields have dropped steadily over the same period. Families report painful, itchy rashes after contact with silt from mining operations, and children have developed long-term coughs since ore stockpiles were built nearby. The mining company, Global Ferronickel Holdings, has stated that laterite is not toxic and is not the cause of losses for farmers or fishermen, nor does it have negative effects on human health. But residents living downstream tell a different story, and the science supports their concern: processed laterite can release nickel and chromium into waterways.

How Mining Deepens Climate Vulnerability and Threatens Indigenous Lands

The damage is not limited to individual livelihoods. Mining-related deforestation and pollution are making entire communities more vulnerable to extreme weather. Residents in Tubajon on Dinagat Island described how the loss of forests and mangroves due to mining operations has left them more exposed to storm surges, high winds, and flooding during events like Super Typhoon Odette in 2021. The severity of flooding is often made worse by failures to manage mining waste, leading to rivers choked with sediment and logs. In the towns of Cantilan, Madrid, and Carmen in Surigao del Sur, residents told researchers that flooding events are becoming more frequent and severe due to the combined impacts of mining and the climate crisis.

Nearly half of all mining permits in the Philippines overlap with important ecological zones, according to a report from Global Witness. This overlap endangers both biodiversity and the rights of Indigenous peoples. The Tampakan Copper-Gold Project, set to start in 2026 on Mindanao, faces strong resistance from the Lumad people, who have lived on and managed those lands for generations. Violence against Indigenous land defenders is widespread, with the Filipino military linked to many cases involving mining conflicts. Multiple individuals, including a prominent anti-mining activist and a local politician, told Climate Rights International that they had been informed that bounties had been placed on their heads due to their anti-mining positions. This pattern of intimidation creates a climate where speaking out carries serious personal risk.

What Gets Missed in the Clean Energy Narrative

The global push for clean energy is often presented as an unqualified good. But the reality on the ground is more complicated. According to modelling, limiting global heating to 1.5°C above preindustrial levels would require almost 300 new mines by 2030, extracting minerals worth close to $800 billion by 2040. Analysis produced for the Guardian found more than 3,267 instances of mining within key biodiversity areas globally, accounting for nearly 5 percent of the sector’s footprint. The Philippines, as a major supplier, is at the centre of this tension.

One thing that often gets overlooked is the destination of the ore. More than 90 percent of Philippine nickel ore exports go to China, where it is processed into nickel for batteries and stainless steel. Exports to Indonesia increased more than 4,000 percent from 2023 to 2024 because Indonesian smelters faced shortages. This means the environmental cost of extraction stays in the Philippines, while the economic value is largely captured abroad. The country is effectively exporting raw materials and importing pollution.

Another nuance: while nickel laterite is not toxic in its undisturbed form, the processing and washing of ore into waterways changes the picture entirely. It can release nickel and chromium, both of which are harmful to aquatic ecosystems and human health. The distinction matters because it shifts the responsibility from the mineral itself to how mining operations manage their waste. When companies fail to contain sediment and runoff, the damage spreads far beyond the mine site.

What Can Be Done: Oversight, Alternatives, and Accountability

There is no single fix for the problems mining creates, but several practical steps can reduce harm and improve accountability. These actions involve government regulators, mining companies, and local communities — each with a distinct role.

Strengthening Environmental Impact Assessments and Monitoring

Current environmental impact assessments (EIAs) often fail to account for cumulative effects — what happens when multiple mines operate in the same watershed, or when deforestation from mining combines with climate-driven extreme weather. Independent, community-involved monitoring of water quality, sediment levels, and biodiversity can catch problems before they become irreversible. Residents in Surigao del Sur have called for regular, transparent testing of rivers and coastal waters, especially after flooding events. The process involves filing requests with the Environmental Management Bureau and local government units, but many communities lack the resources to follow through.

Enforcing Buffer Zones and Waste Management Standards

Mining operations are required to maintain buffer zones between stockpiles and waterways, but enforcement is inconsistent. When laterite ore is washed into rivers, it carries nickel and chromium downstream. Companies must install and maintain silt curtains, sedimentation ponds, and drainage controls. Where these fail — as residents in Palawan and Dinagat Islands describe — the result is contaminated drinking water and lost fisheries. Local governments can conduct spot inspections and suspend operations for non-compliance, but this requires political will and technical capacity that is often lacking.

Supporting Alternative Livelihoods for Affected Communities

For families who have lost their fishing or farming income, compensation from mining companies is often inadequate. Climate Rights International documented cases where residents received payments that did not cover the long-term loss of productivity. Government programs like the Department of Environment and Natural Resources’ Integrated Social Forestry program and the Department of Labor and Employment’s livelihood assistance can provide alternative income sources, but access is uneven. Community-led cooperatives focused on sustainable aquaculture, agroforestry, or ecotourism offer more durable solutions, though they require startup capital and technical training that is not always available.

Emerging Angle: The Role of International Buyers

Most Philippine nickel ore is shipped to China and Indonesia for processing. This means international buyers — particularly battery manufacturers and electric vehicle companies — have leverage they rarely use. Traceability initiatives, such as the ones being developed by the Responsible Minerals Initiative, could allow buyers to source nickel only from mines that meet environmental and human rights standards. If major EV brands demanded certified conflict-free and pollution-controlled nickel, the pressure on mining companies to improve practices would increase significantly. This is still an emerging trend, but it represents one of the most promising avenues for change.

Frequently Asked Questions

Closing Thoughts

The clean energy transition depends on nickel, and the Philippines holds a significant share of the world’s reserves. But the way that nickel is currently extracted is damaging rivers, coasts, and forests — and the people who depend on them — in ways that are not captured in global supply chain reports. The question is not whether mining should happen, but under what conditions, with what safeguards, and who gets to decide.
