The Centre for Social Responsibility in Mining (CSRM) was engaged by Rio Tinto, under the Rio Tinto-CSRM Research Partnership, to undertake a scoping study into the management of project-induced in-migration (PIIM). The study included a review of available literature, evaluation of PIIM studies and management plans, and interviews with PIIM specialists. The purpose of the study was to better understand how extractive companies are responding to PIIM. This knowledge will be used to improve how Rio Tinto responds to population pressure around its mining projects and operations, and will be of interest to other companies and stakeholders such as governments, practitioners, and mine-affected communities.
