Water and Nutrient Management in Natural and Constructed Wetlands [Paperback]

Natural and constructed wetlands play a very important role within the landscape and their ecological services are highly valuable. Water management, including flood water retention, biomass production, carbon sequestration, wastewater treatment and as a biodiversity source are among the most important ecological services of wetlands. In order to provide these services, wetlands need to be properly evaluated, protected and maintained. This book provides results of the latest research in wetland science around the world. Chapters deal with such topics as the use of constructed wetlands for treatment of various types of wastewater, use of constructed wetlands in agroforestry, wetland hydrology and evapotranspiration, the effect of wetlands on landscape temperature, and chemical properties of wetland soils.

Presenting the latest research in wetland science, this volume explores the use of constructed wetlands for wastewater treatment, wetland hydrology and evapotranspiration. Additional topics include the affects wetlands have on landscape temperature and the chemical properties of wetland soils.

Wetlands provide a wide variety of ecosystem services within the landscape and their importance is commonly accepted. Among the most important are regulating services, i.e., benefits obtained from the regulation of ecosystem processes. For example, wetlands contribute to climate regulation. Land cover can affect local temperature and precipitation, wetland ecosystems may affect greenhouse gas sequestration and emissions, or affect the timing and magnitude of runoff and flooding, for example. Wetlands also improve water quality through mechanical, physical, physico-chemical, biological and biochemical processes. These abilities are also used in constructed wetlands but within a more controlled environment. In addition, wetlands provide the supporting services necessary for the production of all other ecosystem services such as soil formation and rel³"
