Adaptive management is the recommended means for continuing ecosystem management and use of natural resources, especially in the context of ‘integrated natural resource management’. Conceptually, adaptive management is simply learning from past management actions to improve future planning and management. However, adaptive management has proved difficult to achieve in practice. With a view to facilitating better practice, this new book presents lessons learned from case studies, to provide managers with ready access to relevant information. Cases are drawn from a number of disciplinary fields, including management of protected areas, watersheds and farms, rivers, forests, biodiversity and pests. Examples from Australia, New Zealand, the USA, Canada, the UK and Europe are presented at a variety of scales, from individual farms, through regional projects, to state-wide planning. While the book is designed primarily for practitioners and policy advisors in the fields of environmental and natural resource management, it will also provide a valuable reference for students and researchers with interests in environmental, natural resource and conservation management.
Built within an exceptional watershed, Montreal is intertwined with the waterways that ring its island and flow beneath it in underground networks. Even as the city has pushed its suburbs deeper into the interior of the island and onto the mainland, the daily lives and leisure activities of its inhabitants remain closely bound to water. Montreal, City of Water focuses on water not only as a physical element of the landscape – both shaping and shaped by urban development – but also as a sociocultural component of the life of the city. In exploring the dynamics governing the relationship between Montrealers and their environment, this unique study considers the role of water in the production and transformation of urban space over two centuries. It traces the history of urbanization and shines a light on current concerns about water pollution, river rehabilitation, and renewed public access to the riverfront – and the power relations involved in addressing those concerns.
The 20th century's automobile-inspired land use changes brought about tremendous transformations in how stormwater moves across the modern urban land-scape. Streets and parking areas in the average urban family's neighborhood now exceed the amount of land devoted to living space. Add parking, office and commercial space, and it's easy to understand how modern cities have experienced a three-fold increase in impervious areas. Traditional wet weather collection systems removed stormwater from urban areas as quickly as possible, often transferring problems downstream. Innovative Urban WetWeather Flow Management Systems does two things: It considers the physical, chemical, and biological characteristics of urban runoff; then describes innovative methods for improving wet weather flow (WWF) management systems. The result of extensive research, Innovative Urban Wet-Weather Flow Manage-ment Systems looks most at how to handle runoff in developments of the 21st century: the confl icting objectives of providing drainage while decreasing stormwater pollutant discharges; the impact of urban WWF on surface and groundwater, such as smaller urban stream channels scoured by high peak flows; sediment transport and the toxic effects of WWF on aquatic organisms; the effectiveness of WWF controls-including design guidelines and source and downstream controls-are an important issue. Innovative Urban Wet-Weather Flow Management Systems looks at how source controls like biofi ltration, created through simple grading, may work in newly developing areas, while critical source areas like an auto service facilities, may need more extensive treatment strategies. Focusing WWF treatment on intensively used areas, such as the 20 percent of streets that handle the bulk of the traffic, and under utilized parking areas is also considered. Developing a more integrated water supply system-collecting, treating, and disposing of wastewater, and handling urban WWF-requires innovative methods, such as a neighborhood-scale system that would recycle treated wastewater and storm water for lawn watering and toilet flushing, or use treated roof runoff for potable purposes.
According to the National Resources Defense Council, stormwater runoff rivals or exceeds discharges from factories and sewage plants as a source of pollution throughout the United States. The Environmental Protection Agency identifies urban stormwaters as the second largest source of water quality damage in estuaries and a significant contributor t
The purpose of this publication is to provide professionals involved in the design and operations of water resource recovery facilities (WRRFs) with a comprehensive reference of current design and operational practices for dealing with the unique challenges associated with the proper management of wet weather flows. Intended as a companion to Design of Municipal Wastewater Treatment Plants, 5th Edition, MOP 8, Wet Weather Design and Operation in Water Resource Recovery Facilities focuses on providing a wet weather flow management perspective to the subject matter previously covered by the widely relied upon design practitioner resource. Going beyond MOP 8 by including operational-oriented considerations related to wet weather events, the text is comprised of 16 chapters, grouped around planning and configuration for wet weather events in WRRFs and facility processes.
