Sven Wunder – författare

Tropical forests are disappearing, giving way to alternative land uses. Sven Wunder gives an economic perspective on deforestation. Following a survey of different deforestation definitions, theories and empirical evidence, a case study of Ecuador provides an historical picture of factors affecting forest loss throughout different periods, regions and ecosystems. It is shown that policy and market failures alone cannot explain why rapid deforestation decision makers follow a composite economic rationale in their continuous clearing of forests which can only be counteracted by concerted action.

Reduction in the size of the world's remaining rainforests is an issue of huge importance for all societies. This new book - an analysis of the impact of oil wealth on tropical deforestation in South America, Africa and Asia - takes a much more analytical approach than the usual fare of environmental studies. The focus on economies as a whole leads to a more balanced view than those that are often put forward and therefore, vitally, a view that is more valid. Of use to those who study environmental issues and economics, this book is potentially an indispensable tool for policy-makers the world over.

A multi-disciplinary team of authors analyze the economics of Brazilian deforestation using a large data set of ecological and economic variables. They survey the most up to date work in this field and present their own dynamic and spatial econometric analysis based on municipality level panel data spanning the entire Brazilian Amazon from 1970 to 1996. By observing the dynamics of land use change over such a long period the team is able to provide quantitative estimates of the long-run economic costs and benefits of both land clearing and government policies such as road building. The authors find that some government policies, such as road paving in already highly settled areas, are beneficial both for economic development and for the preservation of forest, while other policies, such as the construction of unpaved roads through virgin areas, stimulate wasteful land uses to the detriment of both economic growth and forest cover.

Thousands of surveys on rural livelihoods in developing countries are being done every year. Unfortunately, many suffer from weaknesses in methods and problems in implementation. Quantifying households' dependence on multiple environmental resources (forests, bush, grasslands and rivers) is particularly difficult and often simply ignored in the surveys. The results therefore do not reflect rural realities. In particular, 'the hidden harvest' from natural resources is generally too important to livelihoods for development research, policies and practice to ignore. Fieldwork using state-of-the-art methods, and in particular well-designed household questionnaires, thus becomes an imperative to adequately capture key dimensions of rural welfare. This book describes how to do a better job when designing and implementing household and village surveys for quantitative assessment of rural livelihoods in developing countries. It covers the entire research process from planning to sharing research results. It draws on the experiences from a large global-comparative project, the Poverty Environment Network (PEN), to develop more robust and validated methods, enriched by numerous practical examples from the field. The book will provide an invaluable guide to methods and a practical handbook for students and professionals.
