Environmental indicators are the first line of warning against hazards caused by humans or nature catastrophes to prevent diseases and death of living organisms. The present book covers a large variety of environmental indicators from physical-chemistry through economical, bioinformatics, electromagnetic irradiation and health aspects, all dealing with environmental pollution. This volume has been intended to environmentalists, engineers, scientists and policy makers as well to anybody interested in the latest development in the indicator field.

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.

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.

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.

This book includes key environmental indicators endorsed by OECD Environment Ministers and major environmental indicators from the OECD Core Set.

Finding and using indicators that are most suited for tracking progress, raising awareness and supporting analysis is a challenge. Indicators need to be used in appropriate contexts and should ideally be fit-for-purpose. For example, indicators which are best used for awareness-raising cannot be used for monitoring policy goals. This report presents a short review of different indicators typically encountered by environmental policy makers. General advice is provided regarding their uses. In the second part of the report, an overview of the environmental-economic accounting work of the Nordic statistical institutes is presented. Lessons learned from the development of these accounts as well as ideas for future work are described. These types of environmental accounts provide a framework for developing information about the connections between the economy and the environment. The study was commissioned by the Nordic Council of Ministers and conducted by the national statistical agencies in the Nordic countries, led by Statistics Norway and Statistics Sweden.

Sixty indicators giving the first overview of the pressure of human activities on the environment in the EU. Ten policy fields are covered: air pollution, climate change, loss of bio-diversity, marine environment and coastal zones, ozone layer depletion, resource depletion, dispersion of toxic substances, urban environmental problems, waste, and water pollution.

Provides comprehensive data and analysis on the environmental performance of agriculture in OECD countries since 1990, covering soil, water, air and biodiversity and looking at recent policy developments in all 34 countries.

This book outlines an analytical framework to further the analysis of agri-environmental linkages and sustainable agriculture. It describes the main environmental concepts in agriculture of relevance to OECD policy-makers and the indicators that need to be calculated.
