State of the Environment for the Lower Fraser River Basin


Book Description

This report is part of a national series of reports which attempt to provide a summary of the condition of the environment in Canada. It provides an overview of the state and sustainability of the environment of the lower Fraser River Basin, including the physical, biological, and social systems affecting the air, water, land, and fish and wildlife resources. It summarizes the available information and defines some baseline conditions for future state of the environment reporting.

The State of Canada's Environment


Book Description

Second national state-of-the-environment report, addressing the questions of what is happening in Canada's environment, why it is happening, why it is significant, and what Canadians are doing about it. The report is divided into five parts, dealing with perceptions of the environment and the dangers inherent in our tendency to look at the world in terms of human economic models; exploring the state of particular environmental components and the major sectors of human activity; describing six regional case studies; addressing six important environmental issues; and discussing the concept of sustainable development and its implications for Canada's future.




Environmental Aspects of Dredging


Book Description

Expanding a port, deepening a navigation channel or creating new land for development, introduces changes to our physical, social, economic and political environment. Changes may result from events during the construction process, or relate to the nature of the completed structure. Changes can be positive or negative, short-term or long-term, and may affect the immediate vicinity of the project or a larger geographical area. Predicting and assessing all possible effects of a planned dredging activity in a scientifically-sound and reliable manner is essential, so that appropriate control measures can be taken to avoid or mitigate unwelcome impacts. This book provides guidance for a complete holistic environmental evaluation procedure and for the design and implementation of environmental control measures. The book is of particular interest to engineers, government agencies and port authorities, as well as civil engineering consultants and contractors involved in planning and designing dredging, maritime infrastructure and fluvial projects.




The Management of Estuarine Resources in Canada


Book Description

"Estuaries and their associated lands have traditionally provided abundantly for the needs of civilized man. Settlements based on estuarine resources have historically been prosperous, leading the hinterland not only in material wealth but in development and cultural values. They were favoured sites for important cities, attracting commerce and industry, and rising to become keystones to political and economic power. Self renewal of the estuarine environment through daily tidal action and through seasonal fluctuations in water flow permitted intensive use of the resources. Only in recent times, as the estuarine ecosystems were confronted with population and industrial pressures beyond their power to withstand or adjust to, their susceptibility to serious deterioration or destruction was recognized"--Introduction.
