Throughout history, numerous cities worldwide have been settled and built on hillsides, where one can observe the myriad urban challenges they face due to their topographical conditions. However, beyond issues related to their urban infrastructure or transportation systems, which can become more complex due to the geography, hillside urban occupation typically involves various intersections of social, environmental, and economic issues.
These settlements are often inhabited by vulnerable and low-income communities, driven by a variety of motivations. Frequently, the lack of information about certain hazards, coupled with the scarcity of adequate housing policies, leads to decisions and actions that place these communities in high-risk situations, especially during the rainy season, resulting in a cycle that disproportionately affects the most marginalized residents.
