This volume is the second of three addressing a wide range of policy issues relating to the role of public action in combating hunger and deprivation in the modern world. It deals with the background nutritional, economic, social, and political aspects of the problem of world hunger. Volume 2 deals with famine prevention, paying particular attention to sub-Saharan Africa. The topics covered include: the problems of early warning and early action; the politics of famine prevention; the influence of market responses; the role of cash support and employment provision in protecting threatened food entitlements; and long-term issues of reduction of famine vulnerability. In addition to general analyses, the book contains a number of case studies of failures and successes in famine prevention, both in South Asia and in sub-Saharan Africa. Taken together, these essays provide a comprehensive and authoritative analysis of the problem of hunger and deprivation, and an important guide for action.
