Social protection is now considered a development milestone and an important tool in combating poverty. Interventions can include, for example, health insurance, public works programs, guaranteed employment schemes, or cash transfers targeting vulnerable populations groups. This innovative volume is designed to develop understanding about the role and contribution of social protection globally and to share innovative practice and policies from around the world. It explores how to cover an entire population effectively, especially those who are at risk or who are already in a situation of deprivation, and in a sustainable manner. Divided into two parts, the book begins by exploring the theoretical underpinnings of social protection, discussing the social work and social development perspectives and concepts that currently shape it. The second part is comprised of case studies from countries implementing successful social protection initiatives, including Brazil, India, South Africa, Ghana, Nigeria and Indonesia, and reveals how the impact of a successful social protection intervention on poverty, vulnerability and inequality can be dramatic. This volume is an important reference for advanced students and researchers from a range of disciplines including social policy, social work, development studies, geography, planning, economics, sociology, population health and political science.
