The cultural landscape is fashioned from a natural landscape by a
 cultural group. Culture 
is the agent, the natural area is the medium, the cultural landscape is 
the result. Under the influence of a given culture, itself changing 
through time, the landscape undergoes development, passing through 
phases, and probably reaching ultimately the end of its cycle of 
development. With the introduction of a different -- that is an alien -- culture, a rejuvenation of the cultural landscape sets in, or a new 
landscape is superimposed on remnants of an older one... Within each landscape there are phenomena that are not simply there 
but are either associated or independent of each other... the task of geography is conceived as the establishment of a 
critical system which embraces the phenomenology of landscape, in order 
to grasp in all of its meaning and colour the varied terrestrial scene.
