Knowledge of new areas being developed by South (9)
I believe the answer is:
awareness
'knowledge' is the definition.
(awareness is a kind of knowledge)
'new areas being developed by south' is the wordplay.
'being developed' is an anagram indicator.
'by' says to put letters next to each other.
'south' becomes 's' (abbreviation).
'new'+'areas'='newareas'
'newareas' is an anagram of 'awarenes'.
'awarenes'+'s'='AWARENESS'
'of' is the link.
(Other definitions for awareness that I've seen before include "Grasp" , "Perception" , "Knowledge or consciousness" , "Mindfulness, consciousness" , "Consciousness, knowingness" .)
