IG13/BG2.15/SSS6.2Isotope techniques for understanding wetlands and agricultural catchments (co-organized)
|Convener: Philippe Negrel | Co-Conveners: Thomas Hein , Mari Ito , Randall Hunt , Marisol Manzano , Guido Wiesenberg , Delphine Derrien|
Wetland ecosystems are ecologically and functionally significant elements of both the terrestrial and aquatic environments in catchments. They are often important for sustainable water resource management because they contribute to groundwater recharge as well as mitigating the effects of pollution, droughts, and floods. One aim of the session is to explore the use of isotope tracing technique to determine the sources, dynamics, and chemistry of water sustaining catchments and wetlands with the goal of managing the quantity and quality of water in a catchment context. The second aim is, using stable isotope methodologies, to look at the sensitivity of hydrology and biogeochemical processes in catchments and wetlands to specific external influences, especially those related to impact of human activities, like agriculture or global change (e.g. their impacts on organic matter, erosion and water, nutrient and diffuse pollution).
