Seahorse:

I found it interesting that you should note that PRTs, ISAF, NATO themselves are a significant land use/population settlement pattern driver---as much as an attractor as a refugee driver (flight from conflict):

"Urban centres are under tremendous pressures due to in-migration within the 12 major cities which is influenced by operations in the rural areas and the draw of the PRTs and major NATO bases."

Very insightful, and important to remember.
