Between 1999 and 2002 most farming activity stopped in the bands that extended 10 kilometres (6.2 mi) on each side of the newly built oil roads.

That week there was small-scale spear fighting in Pakcur and Nhialdiu in which five people were wounded in revenge for a killing that had taken place three months before.
