Opis

Wetlands occupy some six per cent of the Earth's land surface. They vary from fens and freshwater marshes to tropical mangroves and tundra swamps. They perform vital hydrological, chemical and biological roles and contain unique and diverse forms of wildlife and habitat. They are disappearing at an alarming rate and are threatened by both the direct and indirect effects of human activity. The purpose of this book of especially commissioned articles is threefold: (a) to explore the occurrence and composition of wetlands and their physical and biological dynamics; (b) to consider the impact upon them of agriculture, industry, urbanisation and recreation; and (c) to examine what steps can be taken to manage and to preserve their future survival.

Recenzje

"This is a handsome book on an important subject." Environment and Planning

"A great mine of information, assembled by a distinguished group of authors ... provides a solid background to the wetland debate m... the main strength of the book certainly is its breadth ... this is a remarkably wide–ranging compendium of knowledge." Nature

"The book is enriched with stunning black and white photographs which have been intelligently selected and carefully presented. In the unlikely event of the text not convincing, the photographs and illustrations alone should have the desired impact. Wetlands is a book to have on your bookshelf if you are a working conservationist." Richard Lindsay, The Times Higher Education Supplement

"The reader is certain to learn new facts about wetlands structure and function and to gain new insights into the importance of old facts as they relate to the future of these threatened landscapes." BioScience

The purpose of this comprehensive appraisal of the world′s wetlands is threefold: firstly to explore and to explain the evolution, occurrence and composition of wetlands and their physical and biological dynamics; second, to consider the impact upon them of agriculture, industry, urbanization and recreation; and third, to examine what steps are being and should be taken to manage and to preserve them.
