Some Eden with love gone, abandoned territory (7)
I believe the answer is:
demesne
'territory' is the definition.
(thesaurus)
I can't explain the rest of the clue.
(Other definitions for demesne that I've seen before include "Seed men (anag) -- land attached to a property and retained for the owner's personal use" , "Landed property used by the owner - needs me (anag)" , "Estate; sound like belittle" , "Land attached to manor" , "Large landed property" .)
