A unified theory of conservation that addresses the broad problem of conservation, the principles that inform conservation choices, and the application of those principles to the management of the natural world.The conservation of natural resources, like that of any other asset, involves trade-offs. Yet, in a world faced with the harsh realities of climate change, crafting the right environmental policies is an increasingly urgent task. In Conservation, Charles Perrings and Ann Kinzig bring together new research in economics and biodiversity to investigate conservation decisions and the theory behind them.Perrings and Kinzig apply the concept of conservation broadly to examine how the principles of conservation apply to the management of the natural world. They demonstrate that the same basic principles serve as the foundation of all rational conservation decisions, from managing financial assets to safeguarding at-risk ecosystems. Whether someone is deciding to hold or dispose of a stock or whether to exploit or preserve a natural resource, they are better off choosing to conserve a resource when its value to them, if conserved, is greater than its value when converted. The book also considers the context of such conservation decisions. Just as national tax rules influence choices about financial investments, environmental regulations within countries, and environmental agreements between countries, impact the decisions regarding natural resources. Building on their basic theory of conservation, Perrings and Kinzig address key issues in the field of environmental economics, including the valuation of ecosystem services and environmental assets; the limits on the substitutability of produced and natural capital; and the challenges posed by the often weak markets for ecosystem services oriented toward the public good. They also address the problem of scale: while decisions might be easier to make at the local level, many conservation policies need to apply at either the national or international level to succeed. Written by experts from both social and hard sciences, this book presents a unified theory of conservation and provides a model for a more effective way to approach the vitally important issue.

How will biodiversity loss affect ecosystem functioning, ecosystem services, and human well-being?In an age of accelerating biodiversity loss, this timely and critical volume summarizes recent advances in biodiversity-ecosystem functioning research and explores the economics of biodiversity and ecosystem services. The book starts by summarizing the development of the basic science and provides a meta-analysis that quantitatively tests several biodiversity and ecosystem functioning hypotheses. It then describes the natural science foundations of biodiversity and ecosystem functioning research including: quantifying functional diversity, the development of the field into a predictive science, the effects of stability and complexity, methods to quantify mechanisms by which diversity affects functioning, the importance of trophic structure, microbial ecology, and spatial dynamics. Finally, the book takes research on biodiversity and ecosystem functioning further than it has ever gone into the human dimension, describing the most pressing environmental challenges that face humanity and the effects of diversity on: climate change mitigation, restoration of degraded habitats, managed ecosystems, pollination, disease, and biological invasions. However, what makes this volume truly unique are the chapters that consider the economic perspective. These include a synthesis of the economics of ecosystem services and biodiversity, and the options open to policy-makers to address the failure of markets to account for the loss of ecosystem services; an examination of the challenges of valuing ecosystem services and, hence, to understanding the human consequences of decisions that neglect these services; and an examination of the ways in which economists are currently incorporating biodiversity and ecosystem functioning research into decision models for the conservation and management of biodiversity. A final section describes new advances in ecoinformatics that will help transform this field into a globally predictive science, and summarizes the advancements and future directions of the field. The ultimate conclusion is that biodiversity is an essential element of any strategy for sustainable development.

Bioinvasions and Globalization synthesises our current knowledge of the ecology and economics of biological invasions, providing an in-depth evaluation of the science and its implications for managing the causes and consequences of one of the most pressing environmental issues facing humanity today.Emergent zoonotic diseases such as HIV and SARS have already imposed major costs in terms of human health, whilst plant and animal pathogens have had similar effects on agriculture, forestry, fisheries. The introduction of pests, predators and competitors into many ecosystems has disrupted the benefits they provide to people, in many cases leading to the extirpation or even extinction of native species. This timely book analyzes the main drivers of bioinvasions - the growth of world trade, global transport and travel, habitat conversion and land use intensification, and climate change - and their consequences for ecosystem functioning. It shows how bioinvasions impose disproportionately high costs on countries where a large proportion of people depend heavily on the exploitation of natural resources. It considers the options for improving assessment and management of invasive species risks, and especially for achieving the international cooperation needed to address bioinvasions as a negative externality of international trade.

Environmental external effects are evidence of the inability of market prices to reflect the interdependence of economic activities undertaken within a common environment. They are an essential - not a peripheral - feature of all market economics. This essay shows how external effects are produced by the interaction of the economy with its environment, using a classical mass-balance model. No matter how efficient the market may seem to be, the use of market prices to determine depletion and pollution decisions creates more problems than it solves. Far from sharing the stable or relatively stable equilibrium properties of most economic models, the market economy is shown to be forced by its environment through a seemingly chaotic sequence of states. Reliance on the market to accommodate each change of direction merely exaggerates the general instability of the system. The 'market solution' to environmental problems is shown to generate only increasing uncertainty, a progressive myopia, and a heightened risk of conflict.

This volume reports key findings of the Biodiversity Program of the Royal Swedish Academy of Sciences' Beijer Institute. The program brought together a number of eminent ecologists and economists to consider the nature and significance of the biodiversity problem. In encouraging collaborative work between these closely related disciplines it sought to shed new light on the concept of diversity; the implications of biological diversity for the functioning of ecosystems; the driving forces behind biodiversity loss; and the options for promoting biodiversity conservation. The results of the program are surprising. It is shown that the core of the biodiversity problem is a loss of ecosystem resilience and the insurance it provides against the uncertain environmental effects of economic and population growth. This is as much a local as a global problem, implying that biodiversity conservation offers benefits that are as much local as global. The solutions as well as the causes of biodiversity loss lie in incentives to local users.

This text reports the more policy-oriented results of the Biodiversity programme of the Royal Swedish Academy of Sciences Beijer Institute. The programme brought economists and ecologists together to consider where the problem in biodiversity loss really lies, what costs it has for society, and how it might best be addressed. The results are different from those reported in other works on the subject. Biodiversity loss matters for all ecosystems - not just the megadiversity tropical forests. And it matters because it compromises the resilience and so the productivity of those systems. Biodiversity conservation requires the development of policies that change the behaviour of resource use everywhere - not just in parks and reserves. The book is suitable reading for researchers and policy makers alike. It canvasses options for the reform of park management, biodiversity conservation projects, property rights, tax, trade and price regimes that are within the reach of governments everywhere.

Biodiversity change is the biggest environmental problem of our time. It leads to much more than species extinctions, affecting the food we eat, the diseases we face, our vulnerability to fire and flood, and our ability to adapt to climate change. Our Uncommon Heritage explores the many dimensions of human-driven biodiversity change. It integrates ecology, economics and policy to examine the causes and consequences of changes in ecosystems, species and genes, and to identify better ways to manage those changes. It explores the place of biodiversity in the wealth of nations, the rights and responsibilities people have for natural resources at local, regional, national and international levels, and the challenges faced in protecting the common good at the global level. This is an important book for students and researchers in the fields of conservation and sustainability science, ecology, natural resource economics and management. It also has much to say to those engaged in international conservation, health, agriculture, forestry and fisheries policy.

This authoritative book presents the results of important new research into the economics of biodiversity conservation in sub-Saharan Africa. The contributors offer case studies of the economic causes of biodiversity loss in a range of ecosystem types - wetlands, montane forests, tropical moist forests, semi-arid savannas and lakes - and discuss the policy options for biodiversity conservation in each case. They also provide an in-depth analysis of the environmental consequences of policy reform at the macro- and micro- levels and offer practical recommendations for the implementation of the Convention on Biological Diversity.The Economics of Biodiversity Conservation in Sub-Saharan Africa will prove invaluable to scholars and policymakers working within the areas of environmental economics, environmental science and sustainable development.

Biological invasions - the introduction of living organisms beyond their original range - are one of the main drivers of biodiversity loss. They are a major threat to human health and a source of pests and pathogens in the world's farms, forests and fisheries.The growth of international trade and travel means that more species are being introduced to more places than ever before. This book represents the first concerted effort to understand the economic causes and consequences of biological invasions. The volume discusses the theoretical and methodological issues raised by invasion, including control strategies, modelling options, and a study of the economic, institutional and policy conditions that predispose countries to biological invasions. Also included are case studies of fisheries, agricultural systems, tropical forests and protected areas affected by invasive species in locations such as the Black Sea, Australia and Africa, and an evaluation of control programmes.The Economics of Biological Invasions provides an important first step towards codification of the advice needed to develop decision rules, tools and protocols for the effective management of invasive biological species.This volume will be a fascinating read for researchers, academics and students in ecology, economics and environmental science with an interest in the biodiversity problem. The book will also prove to be essential reading for policymakers responsible for health, agriculture, forestry, fisheries and the environment in both developed and developing countries.

This major authoritative collection prepared by leading figures from North America and Europe presents a careful selection of the most important published articles and papers on ecological economics.Ecology and economics have developed as separate disciplines throughout their recent histories in the twentieth century. A signal contribution of this important collection is that it brings these different traditions together and successfully integrates the natural and social sciences in a volume that will be indispensable to anyone interested in ecological economics.This unique volume contains both classics in the field and contemporary research and gives a coherent picture of the development of the major threads in ecological economics.This collection is a "sampler" in the transdiciplinary field of ecological economics which paints a coherent picture of the development of some of the major threads in this new endeavour. It consists of a selection of both classics in the field and contemporary research, and is intended both for formal courses in ecological economics and for interested independent readers. The book contains 43 papers divided into six sections: 1. Historical Roots and Motivations; 2. Basic Organizing Principles of Ecological Economics; 3. Material and Energy Flows in Ecological and Economic Systems: Theory and Applications; 4. Accounting for Natural Capital, Ecological Limits, and Sustainable Scale; 5.
