Governments throughout the developing world have witnessed a proliferation of non-governmental, non-profit organizations (NGOs) providing services like education, healthcare and piped drinking water in their territory. In Allies or Adversaries, Jennifer N. Brass explains how these NGOs have changed the nature of service provision, governance, and state development in the early twenty-first century. Analyzing original surveys alongside interviews with public officials, NGOs and citizens, Brass traces street-level government-NGO and state-society relations in rural, town and city settings of Kenya. She examines several case studies of NGOs within Africa in order to demonstrate how the boundary between purely state and non-state actors blurs, resulting in a very slow turn toward more accountable and democratic public service administration. Ideal for scholars, international development practitioners, and students interested in global or international affairs, this detailed analysis provides rich data about NGO-government and citizen-state interactions in an accessible and original manner.
