Philippines biodiversity hotspot pushes back on mining
"They told us before the start of their operations that it wouldn't affect us, but the effects are undeniable now," Tambiling told AFP.
"Pangolins, warthogs, birds are disappearing. Flowers as well."
A biodiversity hotspot, Palawan also holds vast deposits of nickel, needed for everything from stainless steel to electric vehicles.
Once the world's largest exporter of the commodity, the Philippines is now racing to catch up with Indonesia. In 2021, Manila lifted a nine-year ban on mining licences.
Despite promised jobs and tax revenue, there is growing pushback against the sector in Palawan.
In March, the island's governing council unanimously passed a 50-year moratorium on any new mining permits.
"Flash floods, the siltation of the sea, fisheries, mangrove areas... We are witnesses to the effects of long-term mining," Nieves Rosento, a former local councillor who led the push, told AFP.
Environmental rights lawyer Grizelda Mayo-Anda said the moratorium could stop nearly 70 proposed projects spanning 240,000 hectares.
"You have to protect the old-growth forest, and it's not being done," she said.'Fearsome' flooding
In southern Palawan's Brooke's Point, a Chinese ship at a purpose-built pier waits for ore from the stockpile overlooking Tambiling's farm.
Mining company Ipilan says increased production will result in greater royalties for Indigenous people and higher tax revenues, but that means little to Tambiling's sister Alayma.
The single mother-of-six once made 1,000-5,000 pesos ($18-90) a day selling lobster caught where the pier now sits.
"We were surprised when we saw backhoes digging up the shore," she told AFP, calling a one-time compensation offer of 120,000 pesos ($2,150) insulting.
"The livelihood of all the Indigenous peoples depended on that area."
On the farm, Tambiling stirred rice paddy mud to reveal reddish laterite he says is leaking from the ore heap and poisoning his crops.
Above him, swathes of the Mantalingahan mountains have been deforested, producing floods he describes as "fearsome, deep and fast-moving."
Ipilan has faced protests and legal challenges over its logging, but its operations continue.
Calls to parent company Global Ferronickel Holdings were not returned.
For some in Palawan, the demand for nickel to power EVs has a certain irony.
"You may be able to... eliminate pollution using electric vehicles," said Jeminda Bartolome, an anti-mining advocate.
"But you should also study what happens to the area you are mining."'First-class municipality'
In Bataraza, the country's oldest nickel mine is expanding, having secured permission before the moratorium.
Rio Tuba employees armed with brooms, goggles, hats and scarves are barely visible through reddish dust as they sweep an access road that carries 6,000 tonnes of ore destined for China each day.
Company senior vice president Jose Bayani Baylon said mining turned a barely accessible malarial swamp into a "first-class municipality".
"You have an airport, you have a port, you have a community here. You have a hospital, you have infrastructure which many other communities don't have," he told AFP.
He dismisses environmental concerns as overblown.
With part of its concession tapped out, the company is extending into an area once off-limits to logging but since rezoned.
Thousands of trees have been cleared since January, according to locals, but Baylon said "under the law, for every tree you cut, you have to plant 100".
The company showed AFP a nine-hectare plot it spent 15 years restoring with native plants.
But it is unclear to what degree that will be replicated. Baylon concedes some areas could become solar farms instead.'Four kilos of rice'
Nearby, Indigenous resident Kennedy Coria says mining has upset Mount Bulanjao's ecosystem.
"Honeybees disappeared where we used to find them. Fruit trees in the forest stopped bearing fruit," the father-of-seven said.
A fifth of the Philippines' Indigenous land is covered by mining and exploration permits, according to rights group Global Witness.
Legally, they have the right to refuse projects and share profits, but critics say the process is rarely clear.
"There are Indigenous peoples who have not received any royalties for the past 10 years," said Rosento.
Coria, who can neither read nor write, said he must sign a document each year when accepting what he is told is his share of Rio Tuba profits.
"We get about four kilos of rice from the community leader, who tells us it came from the company," he said.
Rio Tuba said funds are distributed in coordination with the National Commission on Indigenous People (NCIP), which is meant to represent the communities.
But some say it acts in the interests of miners, attempting to persuade locals to accept concessions and the terms offered by companies.
The NCIP referred questions to multiple regional offices, none of which replied. The government's industry regulator declined interview requests.
While Palawan's moratorium will not stop Rio Tuba's expansion or Ipilan's operations, supporters believe it will slow further mining.
There are looming legal challenges, however.
A recent Supreme Court decision struck down a mining ban in Occidental Mindoro province.
Backers remain confident though, and Rosento said the council would stand firm.
"Responsible mining is just a catchphrase," she said.
