The Routledge International Handbook of Critical Participatory Inquiry in Transnational Research Contexts illustrates how research guided by the emancipatory epistemology of critical participatory inquiry (CPI) can support social change in transnational contexts which are inherently laden with unequal power dynamics and colonial structures. It builds on prior volumes in participatory action research community-based participatory research and decolonizing methodologies. This edited volume offers cases from across the Global South and Global North and from diverse disciplines including human rights migration education health youth studies and development to demonstrate how CPI can fulfill its democratizing and decolonizing potential. Written primarily by new and emerging scholars practitioners and community leaders these cases go on to illustrate how a critical participatory approach to transnational research can enhance the strength of research processes and findings create more equitable and just experiences for those who participate as co-researchers and facilitate social change. Providing a valuable framework for transnational CPI and a wealth of examples it will be an invaluable read for undergraduate and graduate students of Development Studies Healthcare disciplines Education and qualitative research. It will also be of interest to researchers professionals community leaders and even funders and policymakers who want to work toward greater equity and social justice in transnational research contexts.
