The present APAD Bulletin contains a selection of papers presented at the APAD 2010 Conference in Ouagadougou, Burkina Faso, on the theme "Engaging Anthropology for Development and Social Change: Practices, Discourses and Ethics." Anthropological engagements face important challenges at the interface of research and development. The different ways by which anthropologists take on societal problems - either in their research capacity, as development experts, as activists, or as citizen - are inscribed in a longstanding debate. In this APAD Bulletin, the contributors deal with the central questions of how and under which conditions anthropology engages with society. The papers range from epistemological reflections and methodological queries to the anthropology of per diem and of public health, as well as to practical problems confronting anthropologists engaged in development cooperation.
