This report from the United Nations Research Institute for Social Development (UNRISD) warns that current approaches that target the poor or separate poverty from broader processes of economic growth and development are misconceived and will leave approximately one-billion people destitute in 2015. The UNRISD explores the causes, dynamics and persistence of poverty as well as what works and what does not in international policy thinking and practice. It reveals the multiple and complex processes involved in sustainable poverty reduction, and lays out a range of policies and institutional measures that countries can adopt to achieve it.
