This study is devoted to an analysis of the problem of hunger in the modern world and of the role that public action can play in combating it. The book is divided into four parts. The first attempts to provide a coherent perspective on the complex nutritional, economic, social and political issues involved in analysing the problem of hunger in the modern world. The second part deals with famine prevention, paying special attention to Africa. The third part focuses on chronic undernourishment and related deprivations. Parts two and three include a number of case studies of successful public action for the prevention of hunger and famines in various parts of the world. The fourth part draws together the main themes of the book and reconsiders issues connected with the prospects for promoting effective and viable social security systems in developing countries.
