'Improving the productivity and sustainability of agriculture in Africa is one of the pressing challenges of the 21st century. Bluffstone and Köhlin have assembled an authoritative volume of readings on this topic from some of the leading global experts. The book is essential reading for anyone interested in the complex problem of agricultural development in Africa.' -Edward B. Barbier, John S. Bugas Professor of Economics, University of Wyoming 'Stagnant yields, spikes in food prices, and a changing climate have pushed agriculture to the forefront of development concerns. This book provides a masterly microeconomic analysis of what's needed to make farm management more sustainable in Africa, the continent most dependent on agriculture.' -Jeffrey R. Vincent, Clarence F. Korstian Professor of Forest Economics and Management, Duke University 'Undoubtedly we must improve agricultural productivity to reduce widespread and persistent poverty. The sheer lack of agricultural development strategies, however, precludes the implementation of effective policies. This book represents a milestone towards the goal of poverty reduction in East Africa.' -Keijiro Otsuka, Professor of Development Economics, National Graduate Institute for Policy Studies, Tokyo
