Kollam
India
Kollam is projected to face severe climate hazards, including increased heavy rainfall events and frequent heavy precipitation. These patterns are expected to lead to increased flooding and soil erosion risks. The city will also grapple with prolonged drought conditions, disrupting water availability and affecting agricultural yields. Furthermore, the climate is likely to elevate arbovirus transmission risks and significantly increase malaria incidence, threatening public health. As these climate challenges intensify, Kollam will experience interconnected vulnerabilities that pose substantial risks to both the environment and community wellbeing. Effective adaptation strategies are needed to mitigate these looming threats.
Hazard Outlook
How will Kollam's projected climate hazards compare to other cities under a 3.0°C future warming scenario?
Heavy Rainfall Days
With 11 days of heavy rainfall expected, Kollam ranks among the highest of all cities for extreme precipitation events.
Elevation
At 17 m elevation, Kollam faces high risk from coastal flooding and sea level rise.
Maximum Rainfall
Kollam's projected maximum rainfall of 13 mm is higher than most cities globally.
Maximum Temperature
Kollam's projected maximum temperature of 9.0°C is near the median of cities globally under a 3.0°C warming scenario.
Longest Heatwave
Kollam may experience heatwaves lasting up to 5 days, near the median of other cities.
Exposure Summary
Adaptation Priorities
Kollam faces high exposure to heavy rain, elevation and elevated exposure to max rain. These areas may warrant priority attention in adaptation planning.
