ABSTRACT: The regional spatial plan is one of Indonesia's main future goal for development that upholds the prosperity of the people, spesifically in Province of Papua, hence the issuance of the Papua Provincial Regulation on it’s spatial plans, are expected to realize a sustainable spatial planning in Papua and as well restoring the environment’s balance considering the problem of decreasing number of forest areas in Papua that caused by coal mining activities. Therefore, an action of making strict and clear restrictions must be made, if there are no such strict restrictions and arrangements, it eventually will result in environmental damage that will be experienced by our future generations. The effects of enviromental damage which will be experienced by our future generations if this so, are already contradictory with the realization of the principle of intergenerational justice.
