Islands Spawning On Each Other

When Many Players Create An Island It Sometimes Happen That One's Island Is Just Right Next To The Other Or Sometimes EVEN ON TOP OF ANOTHER

This is causing a lot of trouble and dispute, is there a way to turn 1 island per world on? or can u tell me how to fix it? like increase the range of each island in the config?
