In-migration associated with economic opportunity, or project-induced in-migration, is a common phenomenon. This same phenomenon can also negatively affect the project area and host communities, especially with regards to environmental, social and health issues. These negative effects can in turn create social and business risks that jeopardise operations and social stability. A thorough understanding and management of in-migration is necessary to minimise harm, create a stable environment that supports business, and enable social and economic development. This CSRM report presents the first global study of the management of project-induced in-migration at large-scale mining projects. It draws upon a review of available in-migration management plans and interviews with industry practitioners, and describes the current knowledge base within the mining industry, which is limited and incomplete. The report includes a series of recommendations for improved practice, and a check-list of key considerations for managing in-migration for operations facing this complex phenomenon. In the process of conducting this study, we have been able to draw out important linkages with other legacy generating activities, such as resettlement and mine closure. The study was seed funded by Rio Tinto, with further in-kind support from the SMI and UQ to complete the report.
