Economic valuation of biodiversity and ecosystem services is possibly the most powerful tool for halting the loss of biodiversity while maintaining incomes and livelihoods. Yet rarely have such approaches been applied to tropical forest ?hotspots?, which house the vast majority of the planets plant and animal species. This ground-breaking work is the most comprehensive and detailed examination of the economics of environmental valuation and biodiversity conservation to date. Focusing on the Western Ghats of India, one of the top biodiversity hotspots in the world, this volume looks at a cross-section of local communities living within or near sanctuaries and reserve forests such as coffee growers, indigenous people and farmers-cum-pastoralists to assess the use and non-use values that people derive from tropical forests. It also looks at the extent of their dependence on forests for various goods and services, and examines their perceptions and attitudes towards biodiversity conservation and wildlife protection. The book concludes with an assessment of the institutional alternatives and policies for promoting biodiversity conservation through economic valuation methods.

The importance of ecosystem functions for humankind is well known. But only few attempts have been undertaken to estimate the economic value of these ecosystem services. In particular, indirect methods are rarely used, even though they are most suitable for the task. This discrepancy is because quantitative knowledge of changes in ecosystem functions is scarce. This paper presents a user-friendly procedure to quantify the increased N-retention in a renaturated river using easily available data. In a case study of the renaturated River Jossa (Germany) the benefits of increased nitrogen retention caused by beaver reintroduction are determined by using the replacement cost method. The quantification of chemical processes is discussed in detail, as well as the problems of defining an adequate reference scenario for the substitute costs. Results show that economic benefits from the evaluated ecosystem service equal 12% of the total costs of the corresponding conservation scheme.

This thought provoking book draws together prominent international authorities to discuss the key methodological issues and challenges in valuing ecosystem services. Covering a cross-section of ecosystems and services in different sites, countries and

"The international community has committed itself to achieve, by 2010, a significant reduction of the current rate of biodiversity loss at the global, regional, and national levels. Yet, despite growing awareness, and major efforts in all countries, the latest evidence indicates that biodiversity continues to be lost at a terrifying pace, resulting in what some call the greatest mass extinction since dinosaurs roamed the planet, 65 million years ago. A range of methods have been developed to value ecosystems, and the services they provide, as well as the costs of conservation. The methods available are increasingly sensitive, and robust, but they are often incorrectly used. One reason is poor understanding of the purposes of valuation and what questions it can, or cannot, answer. As a result, decision makers may get misleading guidance on the value of ecosystems, and their conservation. In this context, the Bank, IUCN-The World Conservation Union, and the Nature Conservancy have worked together to clarify the aims and uses of economic valuation, focusing on the types of questions that valuation can answer, and the type of valuation that is best suited to each purpose. How Much is an Ecosystem Worth? is the result of that cooperation. It aims to provide guidance on how economic valuation can be used to address specific, policy-relevant questions about nature conservation."

Revised and fully updated, this textbook provides a detailed yet accessible introduction to the key aspects of ecosystem services. Ecosystem services is one of the most powerful guiding principles for ecology, biodiversity conservation and the management of natural resources. It provides the basis of assessing the multiple values and services that ecosystems can provide to humankind, including diverse issues such as carbon sequestration, flood control, crop pollination and aesthetic and cultural services. The second edition of Ecosystem Services: Key Issues has been fully revised and updated to address policy and scientific developments, as well as new and emerging issues, such as nature-based solutions, zoonotic diseases and environmental justice. It includes new and updated case studies from across the world and each chapter contains further reading, learning objectives and discussion questions to aid student learning. The book details the historical roots of ecosystem services in the second half of the twentieth century, through initiatives such as the Millennium Ecosystem Assessment, The Common International Classification of Ecosystem Services (CICES) and the United Nations Sustainable Development Goals. It shows how ecosystem goods and services can be categorised and valued in economic as well as non-monetary terms, while also highlighting some of the difficulties and limitations of valuation techniques. The author describes how themes such as systems thinking, social-ecological resilience and natural capital relate to ecosystem services, and how these can contribute to more sustainable and equitable development. This book will be essential reading for students and scholars of ecosystem services, ecology, environmental science, biodiversity conservation, environmental economics, natural resource management and sustainable development. It will also be of use to professionals and policymakers who are looking to integrate ecosystems and their services into their decision making processes.

Human well-being is dependent upon 'ecosystem services' provided by nature for free, such as water and air purification, fisheries, timber and nutrient cycling. These are predominantly public goods with no markets and no prices, so their loss is often not detected by our current economic incentive system and therefore continues unabated. A variety of pressures resulting from population growth, changing diets, urbanisation, climate change and many other factors is causing biodiversity to decline and ecosystems to be degraded.
