Book excerpt: In 2005, researchers from four Australian universities and CSIRO joined forces with environmental managers from three state agencies and six regional catchment management authorities to answer the question: 'Can we detect the influence of public environmental programs on the condition of our natural resources?' This was prompted by a series of national audits of Australia's environmental programs that could find no evidence of public investment improving the condition of waterways, soils and native vegetation, despite major public programs investing more than $4.2 billion in environmental repair over the last 20 years. Landscape Logic describes how this collaboration of 42 researchers and environmental managers went about the research. It describes what they found and what they learned about the challenge of attributing cause to environmental change. While public programs had been responsible for increase in vegetation extent, there was less evidence for improvement in vegetation condition and water quality. In many cases critical levels of intervention had not been reached, interventions were not sufficiently mature to have had any measurable impact, monitoring had not been designed to match the spatial and temporal scales of the interventions, and interventions lacked sufficiently clear objectives and metrics to ever be detectable. In the process, however, new knowledge emerged on disturbance thresholds in river condition, diagnosing sources of pollution in river systems, and the application and uptake of state-and-transition and Bayesian network models to environmental management. The findings discussed in this book provide valuable messages for environmental managers, land managers, researchers and policy makers.

Download or read book Ecological Indicators for Coastal and Estuarine Environmental Assessment written by João Carlos Marques and published by WIT Press. This book was released on 2009 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book Ecological indicators in coastal and estuarine environmental quality assessment a user friendly guide for practitioners written by Fuensanta Salas and published by Imprensa da Universidade de Coimbra / Coimbra University Press. This book was released on 2006-12-01 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experience demonstrates that none of the available measures regarding biological effects of pollution can be considered ideal, which is due to the complexity inherent in assessing the environmental quality of a system. In fact, it is always preferable to combine a suite of indices providing complementary information. This book aims at helping researchers and students, as well as managers and authorities of coastal areas in selecting the most suitable ecological indicators for each case, taking into account the type of disturbance they want to assess and the data available to do it. A user friendly guide is proposed, accounting different theoretical approaches and discussing the results of its application in different geographical areas. Recommendations are provided regarding the most adequate application of different indices, illustrating for instance in what situations their use is recommendable, or on the contrary not advisable, depending on the characteristics of the disturbance, the type of data, or the level of taxonomic identification of the organisms.

Download or read book Stream Hydrology written by Nancy D. Gordon and published by John Wiley and Sons. This book was released on 2004-06-18 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the publication of the first edition (1994) there have been rapid developments in the application of hydrology, geomorphology and ecology to stream management. In particular, growth has occurred in the areas of stream rehabilitation and the evaluation of environmental flow needs. The concept of stream health has been adopted as a way of assessing stream resources and setting management goals. Stream Hydrology: An Introduction for Ecologists Second Edition documents recent research and practice in these areas. Chapters provide information on sampling, field techniques, stream analysis, the hydrodynamics of moving water, channel form, sediment transport and commonly used statistical methods such as flow duration and flood frequency analysis. Methods are presented from engineering hydrology, fluvial geomorphology and hydraulics with examples of their biological implications. This book demonstrates how these fields are linked and utilised in modern, scientific river management. * Emphasis on applications, from collecting and analysing field measurements to using data and tools in stream management. * Updated to include new sections on environmental flows, rehabilitation, measuring stream health and stream classification. * Critical reviews of the successes and failures of implementation. * Revised and updated windows-based AQUAPAK software. This book is essential reading for 2nd/3rd year undergraduates and postgraduates of hydrology, stream ecology and fisheries science in Departments of Physical Geography, Biology, Environmental Science, Landscape Ecology, Environmental Engineering and Limnology. It would be valuable reading for professionals working in stream ecology, fisheries science and habitat management, environmental consultants and engineers.

Available in PDF, EPUB and Kindle. Book excerpt: Challenges and Innovations in Ocean In-Situ Sensors: Measuring Inner Ocean Processes and Health in the Digital Age highlights collaborations of industry and academia in identifying the key challenges and solutions related to ocean observations. A new generation of sensors is presented that addresses the need for higher reliability (e.g. against biofouling), better integration on platforms in terms of size and communication, and data flow across domains (in-situ, space, etc.). Several developments are showcased using a broad diversity of measuring techniques and technologies. Chapters address different sensors and approaches for measurements, including applications, quality monitoring and initiatives that will guide the need for monitoring. Integrates information across key marine and maritime sectors and supports regional policy requirements on monitoring programs Offers tactics for enabling early detection and more effective monitoring of the marine environment and implementation of appropriate management actions Presents new technologies driving the next generation of sensors, allowing readers to understand new capabilities for monitoring and opportunities for another generation of sensors Includes a global vision for ocean monitoring that fosters a new perspective on the direction of ocean measurements
