Resource mobilization is a major concept in the study of social movements that emerged in the 1970s. It focuses on a movement's ability to acquire and mobilize resources, including financial and in-kind donations, to accomplish its goals. Financial resources are primary and must be solicited from potential donors through identifying sources of funds and pledge activities. In-kind resources like office space or supplies can significantly reduce implementation costs. Effective resource mobilization requires identifying local resources, choosing partners most interested in helping, and developing strategic outreach approaches.
