Ranchi

India

Ranchi is projected to face significant climate hazards in the future, including extreme heat and dangerous heat extremes, with increasing frequency and intensity. The city will experience heavy rainfall events, potentially leading to flooding and water infrastructure challenges. Additionally, Ranchi faces high arbovirus transmission risks, which raise public health concerns. The elevated malaria risk is also likely as climatic changes could create conducive environments for mosquito breeding. These interconnected climate challenges indicate that Ranchi will experience compounded impacts, significantly affecting the health and well-being of the population. Addressing these hazards is crucial for improving resilience and reducing vulnerabilities in the region.
