Antananarivo
Madagascar
Antananarivo is projected to face moderate climate risks that could significantly affect its environment and residents. Key hazards include shifts in rainfall patterns that may lead to both droughts and flooding, impacting local agriculture and water supply. The city will also experience elevated temperatures, exacerbating heat stress for vulnerable populations. Rapid urbanization alongside inadequate drainage systems presents additional challenges during heavy rains, increasing the probability of waterlogging and related health issues. These climate-induced changes highlight the city's vulnerabilities, as the combination of extreme weather events and fragmented infrastructure could impede effective responses to emergencies. Addressing Antananarivo's climate risks necessitates a thorough understanding of these hazards to bolster resilience and protect the community from their adverse effects.
