Official maps are instruments of power, benefitting some while impoverishing others. Inscribed in the law, they fortify the territorial interests of a select few. This is especially apparent in places where the pressures of resource extraction collide with land claims by disenfranchised indigenous groups. In Papua, where capital-rich mining and logging operations rule, local groups are attempting to stem the tide of environmental destruction by creating their own maps; counter-maps that demonstrate ancestral domain. The third week of The Writings on the Wall opens with Nabil Ahmed exploring how to fight a map with a map.
