The urban environment has grown to encompass not just the downtown area of a city but also the suburbs and rapidly growing exurban areas.This growth can affect a wide range of geological, physical, and biological processes. Several sessions at the 23–26 May 2006 Joint Assembly in Baltimore, Md., will explore this topic.
Two union sessions on the “Impact of Urbanization on Environmental Systems” (U31A and U32A) will take place on Wednesday morning, 24 May at 8:30 AM. and 10:45 A.M.The sessions are designed to be a wide-ranging exploration of the different, multiple roles that urbanization, and the changes in the environment that accompany urbanization, have on biological and geophysical processes, said session co-convener Larry Band. Brand is Voit Gilmore distinguished professor and chair of the department of geography at the University of North Carolina, Chapel Hill.
