To mark one year since the disaster, War on Want and London Mining Network marched for 600 km along the basin of the Rio Doce with thousands of people from many different communities, all of whom had been impacted by the Samarco disaster.
In 1988, before civil war broke out in Bougainville, New Zealander Martin Ward was there, leading a team studying the impacts of the contentious Panguna copper mine (controlled by Rio Tinto). Panguna had been operating for about 20 years and generating a lot of money for Rio Tinto and the Papua New Guinea Government but doing little for the people of Bougainville, especially those around the mine.
