Internationally, the wetlands of headwater and upland regions
provide many valuable environmental services. They influence flood
flows, sediment loads and aquifer recharge; biochemical water
qualities and biodiversity. They affect the livelihoods of many
communities providing water, peat, timber, grazing, crops and,
locally, aesthetic, cultural, recreational, nature conservation and
educational benefits. Previously, many of these lands were valued
only for their capacity to be converted to other uses through
drainage and forestation. Today, their benefits are better
appreciated. Better environmental management highlights ways of
bringing enhanced benefits from these lands to all stakeholders and
of minimising their potentially negative impacts due to climatic
emissions of greenhouse gases, hydrological changes (especially
flooding, water chemistry) and sediment release. 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 theirwatershed management
context.
