7Port-au-Prince, Haiti

Port-au-Prince, the capital of Haiti, is plagued by waste management issues, poor infrastructure, and the devastating effects of natural disasters like earthquakes and hurricanes.

The city lacks a formal waste collection system, resulting in mountains of garbage accumulating on streets and in waterways. This improper disposal of waste often contaminates the city’s water sources, leading to the spread of diseases like cholera. With minimal resources allocated to infrastructure development, Port-au-Prince remains one of the dirtiest cities in the world.
