A major challenge in trading ecosystem services is the need to quantify and commoditise services, for monitoring and verification as well as for trade. This is relatively straightforward for goods such as forest honey or shade-grown coffee, but potentially complex for services such as water purification, reducing risk from floods or other disasters or carbon sequestration. Developing certification systems for forest ecosystem services is one potential way to define, quantify and verify these services in a way that buyers can trust, and this is why certification of ecosystem services is promoted by a number of environmental and forestry NGOs. Certification of ecosystem services is a useful concept, but many practical and theoretical obstacles must be addressed before it can be put into practice. This paper is a review of existing development in certification of ecosystem services, with information useful for designing and implementing projects to evaluate the efficacy of new systems. We discuss the potential use of more holistic concepts for measuring management sustainability, which are to date undeveloped and untested, and recommend developing pilot projects that are specifically designed to address a number of challenges inherent to ecosystem service certification.

Natural environments provide enormously valuable, but largely unappreciated, services that aid humans and other earthlings. It is becoming clear that these life-support systems are faltering and failing worldwide due to human actions that disrupt nature's ability to do its beneficial work. Ecosystem Services: Charting a Path to Sustainability documents the National Academies' Keck Futures Initiative Conference on Ecosystem Services. At this conference, participants were divided into 14 interdisciplinary research teams to explore diverse challenges at the interface of science, engineering, and medicine. The teams needed to address the challenge of communicating and working together from a diversity of expertise and perspectives as they attempted to solve a complicated, interdisciplinary problem in a relatively short time. Ecosystem Services: Charting a Path to Sustainability describes how ecosystem services scientists work to document the direct and indirect links between humanity's well-being and the many benefits provided by the natural systems we occupy. This report explains the specific topics the interdisciplinary research teams addressed at the conference, including the following: -how ecosystem services affect infectious and chronic diseases -how to identify what resources can be produced renewably or recovered by developing intense technologies that can be applied on a massive scale -how to develop social and technical capabilities to respond to abrupt changes in ecosystem services -how to design agricultural and aquacultural systems that provide food security while maintaining the full set of ecosystem services needed from landscapes and seascapes -how to design production systems for ecosystem services that improve human outcomes related to food and nutrition -how to develop appropriate methods to accurately value natural capital and ecosystem services -how to design a federal policy to maintain or improve natural capital and ecosystem services within the United States, including measuring and documenting the effectiveness of the policy -how to design a system for international trade that accounts for impacts on ecosystem services -how to develop a program that increases the American public's appreciation of the basic principles of ecosystem services

One of the aims of the CoLUPSIA project is to explore options for establishing payments for ecosystem services (PES) within the two districts where the project is working: Seram and Kapuas Hulu. These guidelines were prepared to support the CoLUPSIA team in completing this assessment and have since been revised to incorporate some findings from the field assessments.

The degradation of ecosystems, including forests, and the associated loss of biodiversity, particularly due to human-induced threats and climate change, has gained increased attention from scientists and policymakers. The Millennium Ecosystem Assessment presented a new conceptual framework that puts ecosystem services at the centre and links human well-being to the impacts on ecosystems of changes in natural resources. The Economics of Ecosystems and Biodiversity initiative drew further attention to the economic benefits of conserving ecosystems and biodiversity, supporting the idea that economic instruments – if appropriately applied, developed and interpreted – can inform policy- and decision-making processes. Only a few ecosystem services, however, have explicit market value and are traded in open markets: many – especially those categorized as having “passive-use” value – remain invisible and are rarely accounted for in traditional economic systems. The failure to appropriately consider the full economic value of ecosystem services in decision making enables the continued degradation and loss of ecosystems and biodiversity. Most ecosystem services are considered public goods and tend to be overexploited by society. Many methods have been applied to the economic valuation of ecosystem services. The use of these methods, as well as the interpretation of their results, requires familiarity with the ecological, political, normative and socio-economic context and the science of economics. Recognizing, demonstrating and capturing the value of ecosystem services can play an important role in setting policy directions for ecosystem management and conservation and thus in increasing the provision of ecosystem services and their contributions to human well-being. The aim of this manual is to enhance understanding of ecosystem services and their valuation. The specific target group comprises governmental officers in planning units and field-level officers and practitioners in key government departments in Bangladesh responsible for project development, including the Ministry of Environment and Forests and its agencies. Most of the examples and case studies presented herein, therefore, are tailored to the Bangladesh context, but the general concepts, approaches and methods can be applied to a broad spectrum of situations. This manual focuses on valuing forest-related ecosystem services, including those provided by trees outside forests. It is expected to improve valuation efforts and help ensure the better use of such values in policymaking and decision making. Among other things, the manual explores the basics of financial mathematics (e.g. the time value of money; discounting; cost–benefit analysis; and profitability and risk indicators); the main methods of economic valuation; examples of the valuation of selected ecosystem services; and inputs for considering values in decision making.

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.

REDD+ is one of the leading near-term options for global climate change mitigation. More than 300 subnational REDD+ initiatives have been launched across the tropics, responding to both the call for demonstration activities in the Bali Action Plan and the market for voluntary carbon offset credits.

Consumption of goods and services represents a growing share of global economic activity. In the United States, consumption accounts for more than two-thirds of gross domestic product. This trend of increasing consumption has brought with it negative consequences for the environment and human well-being. Global demand for energy, food, and all manner of goods is on the rise, putting strains on the natural and human capital required to produce them. Extractive industries and production processes are prominent causes of species endangerment. Modern economies are underpinned by substantial energy consumption, a primary contributor to the current climate crisis. Expanding international trade has led to many economic opportunities, but has also contributed to unfair labor practices and wealth disparities. While certain processes have improved or become more efficient, and certain practices have been outlawed or amended, the sheer scale of global consumption and its attendant impacts continue to be major challenges we face in the transition to sustainability. Third-party certification systems have emerged over the last 15 years as a tool with some promise. There has been anecdotal evidence of success, but to date the overall impact of certified goods and services has been small. Moreover, definitions of sustainable vary across sectors and markets, and rigorous assessments of these programs have been few and far between. In order to take a step in learning from this field of practice, the National Academies' Science and Technology for Sustainability Program held a workshop to illuminate the decision making process of those who purchase and produce certified goods and services. It was also intended to help clarify the scope and limitations of the scientific knowledge that might contribute to the economic success of certified products. The workshop, summarized in this volume, involved presentations and discussions with approximately 40 invited experts from academia, business, government, and nongovernmental organizations.
