Religions are increasingly being regarded as relevant partners in international development cooperation due to their special attributes. However, to date there has been little research into what the special attributes of religious development agencies actually are or how such organisations employ them. What resources do religious NGOs draw on in development cooperation? How do such NGOs differ from other development agencies? Does their engagement make a considerable difference to collaborative development work? Using empirical case studies and theoretical analysis, the contributions in this book address these questions. In doing so, they examine different religions and their collaborative development work in various regions of the world, and chart the most recent changes in religions.
