H43B:
Emerging Issues in Ecohydrology, Agricultural Systems, Land Use Change, and Climate Change in the Tropics II Posters


Session ID#: 7136

Session Description:
Tropical landscapes are remarkably variable, ranging from some of the wettest places on Earth such as humid lowland forests, to high elevation grasslands and even semiarid savannas.  Tropical environments are also undergoing pronounced changes in response to persistent anthropogenic pressure, particularly with respect to changes in land use and climate.  Three billion people worldwide live in tropical regions and depend on important ecosystem services, including freshwater resources and healthy ecosystems.  While temperate regions have been the focus of much ecohydrology research, the tropics remain generally understudied.  This session focuses on emerging ecohydrological issues in tropical environments. Research topics include but are not limited to (1) the influence of landscape characteristics on water cycling and storage; (2) atmosphere–landscape exchange of water, nutrients, and energy, (3) anthropogenic and climate change effects on the water cycle; and (4) interactions between plants, microbes, and water at various spatial and temporal scales.
