International NGOs are increasingly under pressure from governments and the public to demonstrate evidence of impact and positive results. This book critically examines how development NGOs working around the world create knowledge and evidence and use it to satisfy donors to improve their practices and to further our understanding of poverty. It asks questions such as does the evidence of community organizations count as much as higherlevel organizations Should southern NGOs be expected to disseminate preformed development messages What do we mean by evidencebased advocacy The eight studies that form the core of Negotiating Knowledge span scholarly and practitioner research across Africa Asia and Latin America. They tackle political issues that determine what forms of evidence and knowledge are given credence. They explore the power dynamics that shape the value placed on knowledge and learning in relationships within and between organizations. Negotiating Knowledge urges NGOs to examine how they use knowledge in order to make it work better for themselves and for the people that they aim to assist. To do this well they have to understand better what they mean by knowledge and evidence revisit the value that they place on learning and knowledge and invest in appropriate capacity and skills.
