This chapter, Developing a Community of Partners, explores what it takes to develop a community of partners in order for knowledge producers to fill in knowledge gaps. The chapter begins with the basics of partnerships. The basics include a discussion of the need for a shared social context, reciprocity of trust, being a high-performing organization, and having a common purpose. Because partnering involves crossing organizational and knowledge boundaries, tensions, strategies to overcome tensions, and competencies are discussed. A model of intelligence partnerships is provided that includes the perspectives of U.S. policy, non-U.S. policy, publicly available data sources, and intelligence organizations and their data collection capabilities. The implications for climate securityClimate security address a number of structural dilemmas. One is the partnership challenge between national security intelligence organizations whose focus is at the national government level of analysis whereas non-government organizations tend to focus at the subnational level of analysis. A second is the partnership challenge between expertise from the natural versus the social sciences. A third is the challenge between partners from the Global North and the Global South.
