Data from the Global Flood Database indicates that population exposure to flooding has already increased across various countries, with further increases projected across parts of Southern Asia and sub-Saharan Africa. Countries in South America and other regions are also experiencing changes in flood exposure. These patterns highlight how flooding can affect increasingly large populations, placing additional pressure on infrastructure, emergency response capabilities and essential services, particularly in areas where resources are limited.
For travellers and organisations, the implications are wide-ranging. Flooding can disrupt flights, rail services and road transport, sometimes leaving travellers stranded or forcing significant itinerary changes. Beyond travel disruptions, rapidly rising water levels, damaged infrastructure and evacuation requirements can create immediate safety risks. The health consequences can be equally significant, ranging from exposure to contaminated water and infectious diseases to disrupted healthcare access and longer-term psychological impacts. Some risks emerge during the flooding event itself, while others may develop over the following weeks or months.
As 2026 enters its final months, understanding these interconnected risks remains essential for effective travel planning and emergency preparedness. This Flooding Informer examines major developments and emerging trends across the Americas, Europe, the Middle East, Africa and Asia-Pacific, alongside the implications for travel, personal safety and health. It also provides practical guidance to help travellers and organisations make informed decisions, prepare for potential disruptions and navigate flood-related risks.
