Many informal settlements are ill prepared for climate change and face particularly high risks of floods and landslides as a result of poor-quality buildings and a lack of infrastructure to prevent flooding, withstand heavy storms, and cope with heat waves.
Full Answer
Why are informal settlements vulnerable to climate-related hazards?
New settlements are frequently more at risk of, and less able to adapt to, climate-related hazards. Factors contributing to the increased climate vulnerability of informal settlements include housing being located in high-risk areas, poor quality structures, limited access to basic services, and insecurity of land tenure.

What is informal settlement?
Informal settlements include squatter settlements where the occupation of the land is illegal and often contested. They also include “illegal subdivisions”—housing developments that are carried out without official permission but that are not on illegally occupied land. For example, agricultural land that is purchased from the owner and used for residential development in contravention of zoning regulations would be an illegal subdivision. These often have conventional site layouts with room for access roads. It is both easier and less controversial for governments to provide illegal subdivisions with infrastructure and services. Informal settlements are part of a larger “informal” land market where there are often powerful well-connected real-estate interests.
