Fuvahmulah, Maldives

High fertility rates have led to a serious overpopulation crisis in Fuvahmulah, with over 14,000 inhabitants squeezed into just 4.5 by 1.2 km. The availability of land for farming is steadily diminishing, and the poorly constructed roads have contributed to a rise in fatal traffic accidents. Bureaucracy is a persistent headache, with the city council's mandate and structure constantly in flux. On the plus side, Fuvahmulah boasts a wealth of natural wonders, from its white sand beaches and freshwater lakes to its dense tropical forests. But overall, this remote, isolated island is best suited for hardy locals who can navigate its unique challenges.
