The concept of cost-benefit analysis in relation to the assessment of various factors causing stress on natural ecosystems is discussed. It is pointed out that if stress is considered in the context of a deviation from some homeostatic condition, we do face a number of technical and socially related questions. The technical questions are those concerning the need to define in rigorous scientific terms the meaning of ecosystem homeostasis. What is the significance, both temporally and spatially, of a deviation from such homeostasis, and of the elucidation in quantitative terms of the acceptability and nonacceptability of such a deviation. The latter, of course, puts us into our role as scientist-citizens. There we enter the realm of value judgment where we provide only one of many inputs which need to be considered by an institutional decision-maker.

The Ispra Course on Ecological Assessment of Environmental Degradation, Pollution and Recovery'' was structured according to the following topics: (a) terrestrial and aquatic ecosystem concept; (b) structure, functions and evolution of the ecosystem in relation to the natural and anthropogenic influences, and (c) concept of stress, assessment and restoration of terrestrial and aquatic ecosystems. These general concepts were developed in a series of lectures presented by well-known experts in their specific fields, taking into account the ecological principles and environmental management. For the various aspects of the environmental problems, the state-of-the-art, the principles of restoration techniques, the results obtained by their application and the research needs to acquire a better knowledge of the ecological processes, were discussed. The lectures were illustrated by several case studies concerning forests, lakes, reservoirs, rivers, soil and the interrelations between air and terrestrial and aquatic ecosystems.This book contains the lectures presented at the course, reviewed by the authors, and complemented throughout with numerous figures and tables.

Detecting Ecological Impacts: Concepts and Applications in Coastal Habitats focuses on crucial aspects of detecting local and regional impacts that result from human activities. Detection and characterization of ecological impacts require scientific approaches that can reliably separate the effects of a specific anthropogenic activity from those of other processes. This fundamental goal is both technically and operationally challenging. Detecting Ecological Impacts is devoted to the conceptual and technical underpinnings that allow for reliable estimates of ecological effects caused by human activities. An international team of scientists focuses on the development and application of scientific tools appropriate for estimating the magnitude and spatial extent of ecological impacts. The contributors also evaluate our current ability to forecast impacts. Some of the scientific, legal, and administrative constraints that impede these critical tasks also are highlighted. Coastal marine habitats are emphasized, but the lessons and insights have general application to all ecological systems.
