This is what i got from the age wiki.
Development (applied only to the regions inherent, terrain-basic supply generated)
::*Wild = 50%
::*Cleared = 100%
::*Developed = 200%
::*Rich = 300%
:*Transportation Level (added to basic region supply value)
::*None = +0
::*Track = +0
::*Road = +1 (in AJE, is coded as Track)
::*Major Road = +3
:*Bonus to AI if difficulty set on "Hard"
So each terrain type has a coded supply value which goes into a total pot for supply production. That value also impacts foraging so the higher the civ level the more that can be foraged before the province is pillaged.
Example from wiki (age engine)
All supply levels for clear terrain (Supply Level):
:Clear: 4
:Mud: 2
:Snow: 1
:Frozen: 0
So the civ level does help. Clear terrain on a rich level would produce 12 (or clear terrain with a rail road (4+3)*3=21). Of course the structures modified by loyality will greatly exceed this value. Id say civ level would probabally help the most out West where structures are small and therefore terrain supply and foraging are realitavly more important.
