Raja Ampat, an archipelago of around 600 islands in Indonesia’s West Papua province that contains the most biodiverse marine ecosystem on Earth, is being transformed by a growing nickel mining industry driven by demand for electric vehicle batteries — a development that is dividing local communities, threatening irreplaceable coral reefs, and raising uncomfortable questions about what the green energy transition costs and who pays.
Raja Ampat is a collection of some 600 islands in Indonesia’s West Papua province. It is a beautiful area with clear blue waters and coral reefs that is mostly untouched by development except for the recent growth of a nickel mining industry that has split locals.
The phrase “mostly untouched” does significant work in that sentence. Raja Ampat’s coral reefs are not merely beautiful. They are, by the scientific consensus of marine biologists who have spent careers studying them, the most biodiverse marine ecosystem on Earth. The “coral triangle” — the area of the Indo-Pacific containing the highest density of coral and fish species — has its heart here. More than 1,500 species of fish. More than 550 species of coral. Manta rays. Whale sharks. Species that exist nowhere else.
To visit Raja Ampat is, for those who do, a transformative experience. The water is a colour that photographs struggle to capture. The reefs — visible through the surface from a boat — are alive in a way that most of the world’s reefs no longer are. This is what the world’s ocean looked like before humans began degrading it.
And now, nickel mining is moving in.
What Is Happening — and Why
The connection between Raja Ampat’s fate and the global electric vehicle market is direct and uncomfortable. Nickel is a critical component of the lithium-nickel-manganese-cobalt-oxide (NMC) batteries that power most electric vehicles. As EV sales have grown globally — driven by climate policy, consumer preference, and manufacturer commitments — demand for nickel has surged.
Indonesia happens to possess the world’s largest nickel reserves, concentrated in the eastern islands of the archipelago, including areas in and around West Papua. The Indonesian government, under Presidents Joko Widodo and now Prabowo Subianto, has pursued an aggressive strategy of developing those reserves domestically — processing nickel into battery components and finished batteries rather than exporting raw ore — as a route to industrial development and prosperity.
That strategy has produced investment, economic growth, and employment in some areas of Eastern Indonesia where opportunities were previously limited. It has also produced mines — in areas of extraordinary ecological sensitivity that took millions of years of evolution to create and that cannot be rebuilt on any human timescale.
The nickel deposits that are economically most valuable often sit in laterite soils that overlie the watersheds draining into the seas around Raja Ampat. When those soils are disturbed by mining — stripped of vegetation, excavated, transported — the sediment and chemical runoff flows downhill. Into rivers. Into estuaries. Into coral reefs.
Coral reefs are extraordinarily sensitive to water quality. Sediment smothers polyps. Chemical contamination disrupts the symbiotic algae that give coral their colour and their ability to produce food through photosynthesis. Thermal stress — already elevated by climate change — is compounded by land-disturbed runoff. The cascade of stresses that mining introduces into the marine environment is not hypothetical. It has been documented in comparable environments around the world.
The Local Divide
Raja Ampat is a collection of some 600 islands where a nickel mining industry has split locals.
The division within local communities is real and is not easily resolved by outsiders imposing a single narrative. Some communities have been promised jobs, infrastructure, and economic development by mining companies. In areas where traditional livelihoods — fishing, small-scale tourism — have been insufficient to lift communities out of poverty, those promises carry weight.
Other communities — particularly those whose traditional territories include the marine areas most directly threatened by mining runoff — have opposed the mines from the beginning. Their opposition rests on multiple foundations: the value of the reefs for their own traditional fishing, the tourism revenue that Raja Ampat’s diving reputation generates for local homestays and boat operators, and a deep cultural relationship with the marine environment that exists across West Papua’s coastal communities.
The consultation processes through which mining companies and the Indonesian government have engaged with these communities have been criticised by environmental organisations and by affected communities themselves as inadequate. Indonesia’s permitting process for mining in ecologically sensitive areas has been reformed multiple times in recent years, but enforcement of environmental standards remains a persistent problem.
The Tourism Equation
Raja Ampat’s growing international profile as a diving destination has produced economic value that competes directly with mining revenue — and that is at risk from mining impacts on water quality.
The archipelago attracts divers and nature travellers from around the world, generating income for a network of locally owned dive operators, homestays, liveaboards, and supporting businesses. That income flows directly to communities in a way that mining royalties — which are centrally collected and regionally distributed through government processes — often do not.
The tourism economy depends entirely on the quality of the marine environment. Degraded reefs are less visited reefs. Sediment-turbid water is not the impossibly clear blue that Instagram images promise. The economic argument for protecting the reefs is not merely abstract environmentalism — it is a concrete calculation about which land use generates more sustained, locally distributed economic value over time.
That calculation has not consistently prevailed in Indonesia’s development planning decisions, where mining revenues are large and immediate, and the diffuse long-term costs of ecological degradation are politically harder to count.
The Irony of Green Energy
There is an irony in the Raja Ampat situation that deserves to be stated plainly: the world is mining one of its most biodiverse and irreplaceable ecosystems to extract the materials needed to build the electric vehicles and renewable energy systems that are supposed to address the climate crisis.
The green energy transition — essential as it is for reducing global greenhouse gas emissions — is not without its own environmental footprint. Lithium, cobalt, nickel, manganese: the materials that power clean energy technologies must be extracted from somewhere. Where they are extracted, and at what ecological cost, are questions that the global discourse around climate action has not consistently grappled with.
Raja Ampat represents, in concentrated and visible form, the extractive dimension of decarbonisation. The reefs being threatened by nickel mining are ecosystems that have survived ice ages, sea level changes, and millions of years of natural variability. They have not evolved resilience to industrial-scale habitat destruction.
Battery manufacturers and EV companies have responded to this challenge with varying levels of seriousness: some have published traceability commitments for their nickel supply chains; some have invested in research into nickel-free battery chemistries that reduce dependence on Indonesian nickel; some have done neither. Consumer pressure and regulatory requirements for supply chain transparency in major markets — the EU, the US, the UK — are increasing. Whether that pressure translates into meaningful protection for places like Raja Ampat depends on whether the traceability commitments produce real constraints on damaging mining practices or merely better paperwork.
What Needs to Happen
Protecting Raja Ampat’s reefs while meeting legitimate development aspirations in West Papua is not a problem that has no solution. It is a problem that requires political will, regulatory enforcement, and economic alternatives that don’t depend on extracting the substrate that the reefs grow on.
Marine protected area designation — already applied to parts of Raja Ampat’s waters — provides some legal protection. But MPA designation without enforcement is a map, not a fence. Indonesia’s capacity and willingness to enforce environmental restrictions on economically powerful mining interests is the determining factor.
International pressure — from governments, from major corporations with supply chain commitments, from the diving and tourism industry — can influence Indonesian regulatory decisions. The European Union’s battery regulation, which requires traceability for materials in batteries sold in European markets, is one such lever. How effectively it is applied to Indonesian nickel in the years ahead will matter to the reefs.
And within Raja Ampat, the communities that have protected these waters for generations — sometimes formally through indigenous marine tenure systems, sometimes informally through social norms — need to be genuine participants in decisions about the future of their home. Not consultees in a process designed to produce predetermined outcomes, but decision-makers with real authority over what happens in their waters.
Raja Ampat is a beautiful area with clear blue waters and coral reefs that is mostly untouched by development except for the recent growth of a nickel mining industry that has split locals.
The word “mostly” is doing more work than it should. Raja Ampat is not mostly untouched. It is under active threat. And what it contains — those 1,500 fish species, those 550 coral species, that impossibly clear blue water — is not replaceable. When it is gone, it will not come back.
