Dear colleagues, This is a final call for abstracts for the AGU Fall Meeting session on Savannas and Carbon.
Please consider submitting an abstract for this session. A full description is given below. There is an absolute deadline for abstract submission of 11.59 pm on September 6. Authors must be AGU members or have an AGU Member as a sponsor - please contact me if you need sponsorship for submission. Please note that there is no guarantee that this session, or any submission to this session will be designated as an oral presentation, but the more abstracts submitted and the higher the quality, the better the chances. Modelling, land use change and measurement studies from global, to regional, to local scales are welcome.

Description: Savannas are unique among global biomes in the combined and complex role played by rainfall, plant competition, nutrients, fire and herbivory in determining ecosystem dynamics and thus both short-term and long-term carbon sources and sinks. This session seeks to highlight current and planned approaches to assessment of carbon cycle dynamics in the global tropical and temperate savanna biomes, or at regional scale in South, Central and North America, Africa, Europe, Asia and Australia. Papers are invited that explore some of the contrasting factors and problems involved in quantifying the effects of hydrology, land use change, fire, grazing and/or exotic plant introductions. Analyses may utilize varied techniques and approaches using model-data assimilation, remote sensing, biogeochemical, ecosystem and land use change models. The session will seek to provide a broad picture of current approaches, problems and solutions in modeling savanna carbon cycle dynamics, and will foster communication and collaboration among scientists with interests in this field. This will contribute to discussion of models, data and methods that might form a consistent baseline across the regions and research groups. The conveners will invite contributions and accept contributions from responders to this call.
