Indonesia produces 40 percent of the world’s tin. Most of Indonesia’s tin production comes from Bangka Belitung Islands Province. Centuries of mining have changed Bangka’s soil function and left it in a critical state. The tin mining is conducted both on land and in the sea. The dredger exploitation has caused coral reefs to bleach and anglers’catches have reduced to 20%.
This condition worsened after the public mining era, which started from 2000. Many farmers switch profession to tin miners. In addition, the mining management went out of control and disregarded the rules of environmentally friendly mining. The lacks of environmental awareness and unsupportive regional government policy have caused Bangka Belitung landscape to become more and more disordered.
