The purpose of this brief is twofold: to frame the purpose of gender integration for use in displaced and disenfranchised communities in Africa; and to specify how a theory of gender integration and transformation can be applied to specific program objectives, including the design and development of projects; design and use of data collection protocols; development and delivery of training materials; and communication and outreach. To that end, it is important to understand some key terms: gender, intersectionality, and the dynamics of social change. Each of these concepts help to define applied gender integration and transformation in a targeted manner that improves the impact and outreach of research and development projects. The strategy was originally developed for application in the Resource Recovery and Reuse (RRR) in Refugee Settlements in Africa project. Its application was extended to other projects in a refugee context and beyond, as described later.
