There is a meeting scheduled in May 2010 which will add to our understanding on the role of land surface processes within the climate system. It was announced in the following:
We have the pleasure to announce that we are convening the following session at the next General Assembly of European Geosciences Union (EGU) that will take place on 2-7 May 2010 in Vienna, Austria (meetings.copernicus.org/egu2010) :
“Biosphere – Atmosphere Interactions : How can we properly evaluate the role of land-use induced land-cover changes in the climate system? (co-sponsored by iLEAPS)”
(see http://meetingorganizer.copernicus.org/EGU2010/session/2701 for more informations ).
You are invited to submit your abstracts for either an oral or poster presentation before January 18, 2010. For more informations regarding the dead-lines and the abstract format please see the following website :
On behalf of my co-convenors Andy Pitman and Gordon Bonan, we hope to welcome you in Vienna between 2 and 7 May 2010.
Yours sincerely – Nathalie

Recent coordinated simulations, carried out within the LUCID (Land-Use and Climate: Identification of robust impacts) project, have shown that agreement between the models’ responses to similar land-use induced land-cover changes (LULCC) is hard to obtain (Pitman et al. 2009). Part of the dispersion can be attributed to the way land-surface models represent the anthropogenic land (crop, pasture, …). Because such vegetation changes are known to have a large regional impact and potentially a global one, there are a number of unanswered questions that still need to be worked on (addressed):
* How well do the land-surface models simulate the contrasts between natural and anthropogenic land (evaluation of the land models that are embedded within the climate models)?
* What are the respective sign and magnitude of biogeophysical and biogeochemical feedbacks resulting from LULCC?
* How accurate are our global maps of historical vegetation? How well can we predict future LULCC ?
* How well do the models agree in simulating the climatic impacts of LULCC (address both past and future changes with atmosphere-land and atmosphere-land-ocean climate models)?
