Porto-Novo

Benin

Porto-Novo is projected to face increasing climate hazards that significantly threaten its health and environment. The city is likely to experience frequent heatwaves, resulting in heightened heat stress among vulnerable populations. Additionally, prolonged drought conditions are anticipated to disrupt water supply and agricultural productivity, leading to food insecurity. The risk of arbovirus transmission is elevated during these extreme climate events, with potential increases in diseases such as dengue and Zika. Furthermore, the city is expected to confront a higher malaria risk due to changing climate patterns and the proliferation of mosquito populations. These climate challenges underscore the vulnerability of Porto-Novo's ecosystems and public health systems, necessitating a comprehensive understanding of the projected impacts. Without documented technology-enabled solutions to mitigate these risks, the city faces a future where climate hazards could exacerbate existing vulnerabilities, impacting the overall well-being of its inhabitants and economic stability.
