Brazzaville

Republic of Congo

Brazzaville is projected to face multiple climate hazards that threaten its resilience and public health. The city is likely to experience more frequent and intense heatwaves, which could lead to increased heat-related illnesses and stress on resources like water and energy. Additionally, there is an expectation of heightened heavy precipitation events, leading to potential flooding and interruptions to daily life and economic activities. Furthermore, Brazzaville will face increased risks of arbovirus transmission, such as dengue and chikungunya, alongside an elevated risk of malaria due to changing environmental conditions. These projections underscore the growing vulnerability of the city to interconnected climate risks, impacting both health and infrastructure.
