Wetlands are complex and dynamic ecological systems incorporating two important, inter-linked components: hydrology and vegetation. Modelling wetland components and processes reveals the nature of wetland systems and helps to predict the effects of environmental change. The main goal of much current research is the construction of a vigorous and spatially-explicit model which describes the dynamics of wetland vegetation in relation to environmental variables, including hydrological regimes, sediment type and nutrient availability. Knowledge about ecological functions, environmental services and societal values associated with wetlands has increased rapidly. How to turn this knowledge into practical benefits for sustainable and integrated wetland management is a key question. Individual chapters address the ethics and sociology of wetlands, and the ecology, ecohydrology and conservation practice of a variety of landscapes and countries. It will be useful to students, teachers and scientists involved in wetland research and informative for the staff of governmental bodies and other organizations engaged in wetland management.

Forty-two chapters by international experts from a wide range of disciplines make The Wetlands Handbook the essential tool for those seeking comprehensive understanding of the subject. A departure from more traditional treatises, this text examines freshwater wetland ecosystem science from the fundamentals to issues of management and policy. Introductory chapters address the scope and significance of wetlands globally for communities, culture and biodiversity. Subsequent sections deal with processes underpinning wetland functioning, how wetlands work, their uses and values for humans and nature, their sensitivity to external impacts, and how they may be restored. The text is illustrated by numerous examples, emphasising functional and holistic approaches to wetland management, including case studies on the wise use and rehabilitation of wetlands in farmed, urban, industrial and other damaged environments, highlighting the long-term benefits of multiple use. The Wetlands Handbook will provide an invaluable reference for researchers, managers, policy-makers and students of wetland sciences.

Don't drain the swamp!Man's traditional response to swamps, marshes and bogs has been to drain them.But wetlands are not wastelands. Coastal marshes are among the world's most productive ecosystems. They make many commercial fisheries possible and protect coasts from floods and storm surges. Wetlands are pollution filters, water reservoirs. They are among the last wild places on earth, offering homes to endangered plants, birds and animals.Attitudes to wetlands are changing, but not fast enough. As scientists are documenting the wealth in wet places, governments and developers are draining them, damming them, logging them and building resort hotels where ', they once were. Destruction is usually a poor trade-off: well-managed wetlands in Louisiana are producing fortunes in seafood and timber.Waterlogged wealth examines the value of swamps and marshes, as well as the threats against them. In doing so it takes the reader to some of the world's most bizarre landscapes: the 'inland delta' of the Niger River in drought-stricken Mali; the wildlife-rich Okavango swamps of Botswana; the waterlogged Sunderban forests of India and Bangladesh, where tigers eat fish and crabs. Civilisation began around wetlands; today's civilisation has good reason to leave them wet and wild.Dr Edward Maltby is a lecturer in geography at the University of Exeter(UK). He has done extensive research on wetlands both in the North (UK, US, Canada) and the South (Fiji, Jamaica, India and the Falklands/Malvinas Islands). He is on the IUCN Wetland Programme Advisory Committee.Originally published in 1986
