Drylands are a sizeable part of the world's potentially arable land. They vary from the hyper-arid regions of the classic deserts of Africa and Asia to the more common semi-arid and sub-humid areas that support extensive agricultural systems dependent on rainfall or irrigation. Following their successful and innovative work The Economics of Dryland Management the editors have assembled twenty case studies from nine countries in the continents of Africa, Asia, North America and Australia. They help to explore more fully the costs of land degradation and illustrate the economics of reclamation, rehabilitation and prevention. The cases in this book present a rich, varied and readable survey of a wide range of drylands and their resources. Originally published in 19990

We have always had land in which the agricultural productivity is limited because there is not enough moisture. Systems of farming and burning often degrade dryland further until it is desert. Today, however, the problem is becoming much more serious. Over 20 per cent of the world's population lives in dryland areas, and unless action is taken drylands will increase dramatically. This book focuses on the people who live and .farm in the drylands, their use of land resources and the economic returns from their decisions. In a clear and thorough economic appraisal, the authors show how it is still possible to arrest the problem. Originally published in 1989

New Directions in Development Economics is divided into two parts. The first half considers the dilemna of growth with special reference to its environmental cost. The second half focuses on the role of the state in the context of the growing dominance of the free market argument. The contributors include Paul Collier, Partha Dasgupta, Ronald Findlay and Deepak Lal.

It has always been thought that some level of pollution and waste is unavoidable in development projects. But no one has made much effort to quantify and assess the extent of this sort of damage. In this book a group of analysts from the Asian Development Bank and from the East West Center propose a means of constructing useful economic evaluations of the impacts of development projects on the environments in which they are constructed. This study demands the systematic evaluation of all the intentional and unintentional consequences of development initiatives before they are determined upon. It is essential reading for development economists, analysts and bankers. Originally published in 1986

This book applies rigorous economic analysis to the question of sustainable development. It considers the inter-relationship between growth and sustainability showing that one does not necessarily exist to the detriment of the other. Sustainability may be measured and defined in national accounting terms and the contributors explore a potentially powerful theoretical definition. Case studies on Morocco and China examine some of the domestic policy requirements of sustainability, revealing the desirability of quite complex combinations of policies. International policy aspects of sustainability are considered, such as technology transfers and the establishment of workable agreements to reduce global pollution. The volume demonstrates the need to build the sustainability debate on sound economic foundations, and the ability of economists to provide such foundations.

Bringing together case studies from Kenya, Benin, Cameroon and the Philippines, this volume provides a multidisciplinary overview of the economics of natural resource management in Tropical regions, at household and village level. By comparing a wide array of climatic and economic conditions, it examines the effect of location and access to the market - as well as the importance of national policies - have on soil and water conservation. The book not only analyzes the benefits of soil and water conservation based on econometric studies, but also assesses the costs involved. In doing so it challenges commonly held assumptions about poorer community's ability to finance such measures.
