Port Louis
Mauritius
Port Louis is projected to experience a future characterized by frequent heavy precipitation, increasing the likelihood of flooding and related infrastructure damage. The city will also face an elevated risk of arbovirus transmission, which is associated with higher rates of diseases carried by mosquitoes due to increased rainfall and standing water. Furthermore, the region is expected to encounter a heightened threat of malaria, as warmer and wetter conditions could favor mosquito breeding. These climate hazards collectively threaten public health and infrastructure, necessitating a deeper understanding of vulnerability and risk management strategies. The combination of these factors indicates a pressing need for comprehensive assessment and proactive measures to mitigate future impacts as the climate continues to change. Port Louis's future resilience may be compromised without documented solutions to address these challenges.
