Sana'a

Yemen

Sana'a is projected to face an increasingly challenging climate future characterized by frequent heatwaves and heavy precipitation. The frequency of heatwaves will likely lead to heightened temperature extremes that can impact both public health and energy demands, straining resources and infrastructure. Concurrently, the prevalence of heavy precipitation poses risks of flooding, which could damage infrastructure, disrupt transportation, and affect water quality. These climate hazards combine to create a precarious situation, as the city may struggle to cope with the dual challenges of extreme heat and excessive rainfall. Vulnerabilities within the urban landscape could exacerbate the effects of these climate risks, leading to potential threats to food security, water availability, and overall community resilience. Without documented technology-enabled climate resilience solutions, the potential consequences of these hazards remain a significant concern for the residents and governance of the city as they navigate an uncertain environmental future.
