This report examines local knowledge integration in the context of global development and humanitarian aid work. It builds upon a recently published report by the U.S. Agency for International Development (USAID) called Integrating Local Knowledge in Development Programming. That report sought to “share knowledge of how development donors and implementing organizations leverage local knowledge to inform programming.”. This study aims to extend the original methods to better understand grassroots actors’ own interpretations of local knowledge and its integration into programming in their communities. It examines the perspectives of 29 grassroots leaders from women-led organizations around the world, looking deeply at the ways in which they conceptualize local knowledge and local knowledge stakeholders, their approaches to designing their own projects based on local knowledge, and their experiences sharing knowledge with international actors and donors. This builds the broader evidence base on integrating local knowledge to incorporate the perspectives of grassroots actors into the same conversation as the original study.
