Economic valuation can help improve decisions about protecting the environment . By inputing values to unpriced goods, it can make public choices more cost-efficient and thus allow limited public income to be optimally spent.

The author looks at the challenge facing agriculture today and details the concepts and characteristics of alternative, sustainable agricultural practices. Empirical evidence from a diverse range of agro-ecological and community setting show the impact of more sustainable practices. In addition existing policy frameworks and institutional processes are considered and alternatives, which are known to work, are presented

A systematic account of values carried by the natural world.

As the world faces unprecedented challenges such as climate change and biodiversity loss, the resources needed far outstrip the capabilities of nonprofits and even governments. Yet there are seeds of hope—and much of that hope comes from the efforts of the private sector. Impact investing is rapidly becoming an essential tool, alongside philanthropy and government funding, in tackling these major problems. Valuing Nature presents a new set of nature-based investment areas to help conservationists and investors work together. NatureVest founder William Ginn outlines the emerging private sector investing opportunities in natural assets such as green infrastructure, forests, soils, and fisheries. The first part of Valuing Nature examines the scope of nature-based impact investing while also presenting a practical overview of its limitations and the challenges facing the private sector. The second part of the book offers tools for investors and organizations to consider as they develop their own projects and tips on how nonprofits can successfully navigate this new space. Case studies from around the world demonstrate how we can use private capital to achieve more sustainable uses of our natural resources without the unintended consequences plaguing so many of our current efforts. Valuing Nature provides a roadmap for conservation professionals, nonprofit managers, and impact investors seeking to use market-based strategies to improve the management of natural systems.

"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."

Biodiversity loss is one of the major resource problems facing the world, and the policy options available are restricted by inappropriate economic tools which fail to capture the value of species and their variety. This study describes in non-technical terms how cost-benefit analysis techniques can be applied to species and species loss, and how they provide a measure of the efficiency of conservation measures. Only when conservation can be shown to pass such a basic economic test, the authors claim, will it be incorporated into policies.;David Pearce has also written Blueprint for a Green Economy.
