Internationally, the wetlands of headwater and upland regions provide many valuable environmental services. This book moves towards a more comprehensive inventory of the benefits and costs of headwater wetlands. It evaluates the research that tries to understand the tolerances, exchanges, checks and balances within headwater landscapes and the downstream impacts of changes in wetlands. It employs case studies and reviews from 21 nations spanning Europe, Africa, Asia and the Americas. It explores the new policy frameworks, changes in land husbandry, new systems for community education, participatory processes and technological interventions required for the effective management of headwater wetlands and the full integration of wetlands (including newly constructed wetlands) into environmental management and planning. In the past, most research dealt with wetlands as isolated features, this book examines wetlands in their watershed management context.

Sees wetlands in context Considers wetlands in headwater upland and mountain regions Holistic examination of wetlands in their wider environmental, hydrological and socio-economic contexts most previous work treated wetlands in isolation Outcome of the 'Nairobi Declaration for the International Year of Freshwaters' 2003
