JATAM is open to those, both organizations and individuals, who are eager to fight against the injustices caused by mining. Many people and resources are needed to achieve JATAM’s objectives. JATAM’s constituents include individuals, communities victimized by mining, and NGOs committed to mining advocacy.

JATAM is a network movement whose components consist of a village node, regional/island node, national node, a regional board and a support body. Each node possesses autonomy for managing it’s own network.
