Faktors Contributing to Vulnerability

Vulnerability is not solely a function of geography. It is shaped by a web of interrelated factors that determinate a city 's ability to considerate, cope with, and recover from climate impacts. understanding these factors is critical for designing effective adaptation strategies.

Wybrzeże Proximity andTopography

Loww elevation and coproximy too water bodies naturally increase exposure te sea- level rise, storm surges, and flooding. Cities built on land that is subsiding due to natural or antropogenic reasons (e.g., groundwater extraction, oil ands extraction) face even greater relativa sea- level rise. Topography also influeres landslide risk; for exampleme, the hilliside settlements of Rio de Janeiro (Brazil) and La Paz (Bolivia) are pre pre mudslides during bry rains.

High population density density strains infrastructures, especially in informal settlements whe building codes are note forced. Crowded neighhood witch impervious surfaces incredibate fooding and heat islant effects. The layout of a city - whether it has parks, green corridors, and permeable surfaces - directly fects its microclimate. Cities with sprawling, car- designs tend to have larger heat islands and highier percapitalia emissions.

Infrastructure Resilience andAge

Old infrastructure - sewer systems, roads, power grids, water treatment plants - is often not designed for current climate extremes. For example, man U.S. cities have combined sewer systems that overflow during hevy rain, builing waterways.
