A new goal - redeveloping land (6)
I believe the answer is:
angola
'land' is the definition.
(African country)
'a new goal redeveloping' is the wordplay.
'new' becomes 'n' (common abbreviation eg NT for New Testament).
'redeveloping' is an anagram indicator (I've seen 'redeveloped' mean this).
'goal' is an anagram of 'gola'.
'a'+'n'+'gola'='ANGOLA'
(Other definitions for angola that I've seen before include "Luanda is its capital city" , "SW African state" , "SW African country" , "South-west African country, capital Luanda" , "Country of south-western Africa" .)
