Neighbour of Namibia (8)
I believe the answer is:
botswana
(Other definitions for botswana that I've seen before include "Boa wasn't found out in the Africa" , "South African country" , "Boa wasn't found in the African state" , "African country, setting for "The No. 1 Ladies' Detective Agency"" , "Country east of Namibia, north of South Africa" .)
