In Africa it's a uni, possibly (7)
I believe the answer is:
tunisia
'in africa' is the definition.
('Tunisia' is part of 'africa')
'it's a uni possibly' is the wordplay.
'possibly' indicates an anagram.
'its'+'a'+'uni'='itsauni'
'itsauni' with letters rearranged gives 'TUNISIA'.
(Other definitions for tunisia that I've seen before include "Country between Algeria/Libya" , "Country where Carthage is found" , "Land" , "country-style" , "African state" .)
