Completely different method, using a script of mine, since you have paths:
1) In the Paths dialog, make all paths visible (shift-click the eye icon on any of them), and then "Merge visible paths" (you end up with one single path)
2) The the freehand selection to make a rough selection around South America
3) In the Path list, right click the path, and go to Edit>Extract strokes. You will get a path restricted to South America
4) Then Select>From path and bucket-fill
Step 3) assume you installed ofn-path-edits from here
PS to the usual suspects: this particular used uncovered a bug, the just-uploaded SourceForge version is fixed.
