Book Description
Ecological indicators address ecosystems structure and/or function and are commonly used to provide synoptic information about their state. Through quantitative representations of either the forces that steer ecosystems, responses to forcing functions, or of previous, current, or future states of an ecosystem, indicators are expected to reveal conditions and trends that will help in development planning and decision making processes. Ecological indicators combine numerous environmental factors in a single value, which may be useful in terms of management and in the development of ecological concepts, compliant with the general public's understanding. Nevertheless, their application is not exempt of criticisms, the first of which is that aggregation results in an oversimplification of the ecosystem under observation. Ecological indicators must therefore be handled following the right criteria and in situations that are consistent with its intended use and scope; otherwise they may drive to confusing interpretations of data.

Book Description
Ecological indicators and surrogates are used widely by resource managers to monitor and understand complex biota and ecosystem processes. Their potential to guide complex resource management has meant they have been proposed for use in all ecosystems worldwide. Despite extensive research into indicators and surrogates, there remains much controversy about their use, in addition to major issues and knowledge gaps associated with their identification, testing and application. Indicators and Surrogates of Biodiversity and Environmental Change provides insights into the use of indicators and surrogates in natural resource management and conservation – where to use them, where not to use them, and how to use them. Using an ecological approach, the chapters explore the development, application and efficacy of indicators and surrogates in terrestrial, aquatic, marine and atmospheric environments. The authors identify current gaps in knowledge and articulate the future directions for research needed to close those gaps. This book is written by the world’s leading thinkers in the area of indicators and surrogates. It is the first major synthesis of learnings about indicators and surrogates and will be a critical resource for the vast number of people developing and applying them in ecosystems around the world. It will be an essential resource for scientists, policy makers and students with interests in surrogates and indicators.

Book Description
While the concept of sustainability has been widely embraced, it has been only vaguely defined and is exceedingly difficult to measure. Sustainability indicators are critical to making the broad concept of sustainability operational by providing specific measures by which decision makers and the public can judge progress. Sustainability Indicators defines the present state of the art in indicator development. It presents a comprehensive assessment of the science behind various indicators, while placing special emphasis on their use as communications tools. The contributors draw on their experience as academics and practitioners to describe the conceptual challenges to measuring something as complex as sustainability at local, regional, national, and global scales. The book also reviews existing indicators to assess how they could be better employed, considering which indicators are overused and which have been underutilized. Sustainability Indicators will help planners and policy makers find indicators that are ready for application and relevant to their needs, and will help researchers identify the unresolved issues where progress is most urgently needed. All readers will find advice as to the most effective ways to use indicators to support decision making.

Book Description
Nematodes are the most wide spread multicellular animals in nature and analysis of nematodes in terrestrial, freshwater and marine environments as well as their role and function in ecosystems, can be used for environmental monitoring. Compared to other organisms, they offer the greatest potential as bioindicators and can be used to study gene expression in relation to environmental challenges, to monitor changing impacts on the environment and in laboratory ecotoxicity tests. This volume addresses classical and molecular approaches to nematode community analysis, the contemporary field of nematodes as biosensors, as well as genomic aspects of nematode bioindicators. In addition, the case studies stress the importance of these bioindicators and demonstrate the commercial potential of these technologies.

Book Description
Praise for the first edition: 'This book should be of interest to anyone interested in sustainable development, and especially sustainability indicators. Bell and Morse easily succeed in exposing the fundamental paradoxes of these concepts and, more importantly, they offer us a way forward. Readers ... will find their practical recommendations for those attempting to do sustainability analysis in the field most welcome, which is also the book's greatest strength.' Local Environment: The International Journal of Justice and Sustainability 'This book makes a valuable contribution to the theory and practice of using indicators for sustainability. It introduces systems ideas and a range of tools and techniques that have the potential to broaden and deepen our understanding of a whole range of complex situations. Well worth a closer look.' Christine Blackmore, Open University 'This is a book that explores new ways of thinking about how to measure sustainability... It offers stimulating food for thought for environmental educators and researchers.' Environmental Education Research 'This book tells me, as an SI 'practitioner', where I have been and why, and more importantly how I should be thinking in order to effectively present to and empower the local community in the years ahead.' David Ellis, Principal Pollution Monitoring Officer, Norwich City Council 'A practical guide to the development of sustainability indicators which offers a systemic and participative way to use them at local scale. Our preliminary results are highly positive and the approach is applicable in many contexts.' Elisabeth Coudert, Programme Officer Prospective and Regional Development, Blue Plan The groundbreaking first edition of Sustainability Indicators reviewed the development and value of sustainability indicators and discussed the advantage of taking a holistic and qualitative approach rather than focusing on strictly quantitative measures. In the new edition the authors bring the literature up to date and show that the basic requirement for a systemic approach is now well grounded in the evidence. They examine the origins and development of Systemic Sustainability Analysis (SSA) as a theoretical approach to sustainability which has been developed in practice in a number of countries on an array of projects since the first edition. They look at how SSA has evolved into the practical approaches of Systemic Prospective Sustainability Analysis (SPSA) and IMAGINE, and, in particular, how a wide range of participatory methodologies have been adopted over the years. They also provide an assessment of the strengths and weaknesses of projects that undertake work in the general field of sustainable development.

Book Description
The field of ecosystem health explores the interactions between natural systems, human health, and social organization. As decision makers require a sound, modular approach to environmental management and sustainable development, ecosystem health assessment indicators are increasingly used across any number of applications.
