Invasive non-native species are a major threat to global biodiversity. Often introduced accidentally through international travel or trade, they invade and colonize new habitats, often with devastating consequences for the local flora and fauna. Their environmental impacts can range from damage to resource production (e.g. agriculture and forestry) and infrastructure (e.g. buildings, road and water supply), to human health. They consequently can have major economic impacts. It is a priority to prevent their introduction and spread, as well as to control them. Freshwater ecosystems are particularly at risk from invasions and are landscape corridors that facilitate the spread of invasives.
This book reviews the current state of knowledge of the most notable global invasive freshwater species or groups, based on their severity of economic impact, geographic distribution outside of their native range, extent of research, and recognition of the ecological severity of the impact of the species by the IUCN. As well as some of the very well-known species, the book also covers some invasives that are emerging as serious threats. Examples covered include a range of aquatic and riparian plants, insects, molluscs, crustacea, fish, amphibians, reptiles and mammals, as well as some major pathogens of aquatic organisms.
The book also includes overview chapters synthesizing the ecological impact of invasive species in fresh water and summarizing practical implications for the management of rivers and other freshwater habitats.
These three volumes present an original exploration of all aspects of water--social, cultural, political, religious, historical, economic and technological--from ancient times until the present day. Among the varied themes, the contributors examine the changing histories of water as a private or common good, the politics of water at local, urban, national and international level, water in cities, great river plans, dams, river biographies, and cultural constructions of water--images of water in religion, myth, literature and art. With empirical and ethnographic case studies from around the world the three volumes together represent one of the most complete and up to date accounts of the central role of water in the history and development of humanity.
A futuristic approach in water management has been discussed in this descriptive book. It is estimated that there is nearly 1.4 billion km3 of water in this world but only about 3% (39 million km3) of it is available as fresh water. Furthermore, most of this fresh water is found as ice in the arctic regions, atmospheric water or deep groundwater. Since water is a source of life and is vital for all forms of life across the planet, its sustainable use is an extremely crucial issue. Water Management is the fundamental term employed for elucidating all the activities involved in managing the optimum use of the world's water resources. However, only a small percentage of fresh water available can be subjected to water management. It is still a huge amount, but the distinct characteristic of water is that unlike other resources, it is irreplaceable. This book describes an elementary analysis on several topics related to water management from across the globe. The topics elucidated in this book cover politics, recent models for water resource management of rivers and reservoirs as well as issues associated with agriculture. Growing water demands, water quality problems and water pricing have also been considered. Reputed scientists and experts from across the world have contributed descriptive information in this book. It covers a broad range of current issues, describing the current problems and illustrating the complexity of water management.
