despite the government revoking several permits, a report warned Thursday. Analysis of recent and historic mining in the region showed a "domino effect of destruction," ranging from deforestation on land to sediment run-off smothering coral reefs, the report by NGOs Auriga Nusantara and Earth Insight said.

"Post-mining rehabilitation is very poor," Auriga Nusantara executive director Timer Manurung told AFP. "We worry that the current nickel mining will impact Raja Ampat for decades to come." Raja Ampat is part of the famed Coral Triangle, beloved by divers for its marine riches. In June, Indonesia's government revoked permits for four of the five nickel mining companies operating in the cluster of islands and shoals in Southwest Papua Province. That followed an outcry from activists and residents over the impact of mining for the metal used in everything from stainless steel to electric vehicles. In September, the government allowed one company -- PT Gag Nikel -- to restart operations, arguing the impact "can be properly mitigated." But NGOs say serious damage has already been done, and there is little sign of clean-up. (bssnews)
