Resilience Scanner

San Salvador is projected to face significant climate hazards, including frequent heatwaves and prolonged drought conditions that threaten water availability and agriculture. These extreme temperature events can adversely impact health, leading to increased morbidity. Additionally, the city will experience a high risk of arbovirus transmission, potentially resulting in outbreaks of diseases such as dengue fever. Alongside this, heightened malaria risks are anticipated, driven by climate changes that favor mosquito populations. The convergence of these factors suggests an increasingly challenging environment, highlighting the urgent need for a comprehensive understanding of San Salvador's climate vulnerabilities to prepare effectively for the future.
