Land in Haiti, a lot of open ground (8)
I believe the answer is:
ethiopia
'land' is the definition.
(I know that Ethiopia is a African country)
'haiti a lot of open ground' is the wordplay.
'a lot of' means to remove the last letter (a lot of but not all of the word).
'ground' indicates an anagram ('grind' the letters into a new form).
'open' with its last letter removed is 'ope'.
'haiti'+'ope'='haitiope'
'haitiope' anagrammed gives 'ETHIOPIA'.
'in' is the link.
(Other definitions for ethiopia that I've seen before include "Country formerly called Abyssinia" , "Modern Abyssinia" , "Tie a Hopi up in Africa" , "Where Haile Selassie was once emperor" , "Landlocked Afr. country" .)
