Book excerpt: One of the most promising approaches to poverty reduction in developing countries is to encourage sustainable livelihoods for the poor. This takes account of their opportunities and assets and the sources of their vulnerability. Based on recent and extensive research, this volume thoroughly assesses the value of the livelihoods approach to urban poverty. The book reviews the situation and strategies of the urban poor and identifies the policies and practical programmes that work best. Lasting improvements depend not just on economic development, but on political commitment and structures that are responsive to the claims and needs of different groups of poor people.
