How Much Is An Ecosystem Worth

"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."

Value is a practical guide that explains the most important steps and techniques for the valuation of ecosystem services, and the incorporation of its results in decision making. It explains, step by step, how to generate persuasive arguments for more sustainable and equitable development decisions in water resources management.

The ecosystem approach embodies a concept of the environment which emphasizes the integrated components of nature as complex adaptive systems. This book examines the relationship between the architecture and design of environmental law and the implementation of the ecosystem approach as a means to maintain ecological integrity. The main issue addressed is: in which manner and to what extent does fragmentation and administrative discretion in environmental law impede the implementation of an ecosystem approach? This is explored through analysis of several questions: what is an ecosystem approach and how could it be implemented; how can economic evaluation of ecosystem services contribute to the debate; to what extent is environmental law fragmented and how does this affect the implementation of the ecosystem approach; to what extent does environmental law contain administrative discretion and how does this affect the implementation of the ecosystem approach; is there a need for greater consistency, coherence and a stronger rule of law in environmental law in light of the ecosystem approach? The main focus is on Europe, with additional international comparisons where appropriate. The book concludes by providing a normative portrayal of future environmental law as protective, systemic and predictable.

Ecosystem Management and Sustainability analyzes myriad human-initiated processes and tools developed to foster sustainable natural resource use, preservation, and restoration. It also examines how humans interact with plant, marine, and animal life in both natural and human-altered environments. Experts explain the complex ecosystem relationships that result from invasive species, roads, fencing, and even our homes by addressing topics such as fire and groundwater management, disturbance, and ecosystem resilience. Because most people in the 21st century live in urban environments, the volume pays special attention to the ecology of cities, with detailed coverage on topics ranging from urban agriculture to landscape architecture. The volume focuses on how ecosystems across the world can be restored, maintained, and used productively and sustainably.

In this volume of the TEEB (The Economics of Ecosystems and Biodiversity) publication series, the key concepts of the project are applied to local and regional policy and public management. The aim is to show that by taking nature's benefits into account, decision makers can promote local development to ensure human well-being and economic growth and stability, while maintaining environmental sustainability. The book explores the potential for local development provided by an approach based on nature. It offers examples of successful implementation of this approach from across the world, highlighting the importance of local decision making in management and planning. It provides tools and practical guidance for reform, and throughout the volume the economic benefits of environmental consideration at a local level are expounded. This book is intended to offer inspiration and practical suggestions for the improvement and sustainable management of the environment and human well-being. The local aspect of this book complements the focus of the previous three volumes, completing the set to provide a comprehensive approach to simultaneously improving and maintaining economic and environmental stability, as well as human well-being.
