The SBC field is made up of a diverse and varied range of organizations and actors, but we are united in shared recognition of SBC's importance in achieving the Sustainable Development Goals (SDGs). This session will explore how diverse organizations can work together for the common good of the field to advocate for the investment and support for SBC. Speakers representing networks or alliance of diverse SBC organizations at the national, regional, and/or global scale will share lessons learned about bringing groups of organizations that work on various issues and sectors together for a more substantial collective impact. The session will end with a discussion of recommendations for how networks operating at different levels (i.e, national, regional, and global) can increase impact by working together and creating stronger reciprocal connections between the national, regional and global work.
