Examining the problem of hunger in the modern world and the role public opinion might play in combatting it, Drèze and Sen here provide a coherent perspective on the complex nutritional, economic, social, and political issues involved in the analysis of hunger. They explore famine prevention through a series of case studies in Africa and elsewhere, and discuss the problem of chronic undernourishment. Sen was awarded the second Agnelli Prize for the Ethical Dimension in Advanced Societies in March 1990 in recognition of his outstanding contribution to the understanding of the ethical dimension in modern society.
