Webinar Introduction

In late November-early December 2025, unprecedented monsoon rains and overlapping tropical storms unleashed catastrophic flooding across parts of Southeast Asia and South Asia, with some of the worst impacts in Indonesia, Sri Lanka, and Thailand. These events have resulted in a devastating humanitarian toll, with well over 1,400 people reported dead across the three countries and nearly 1,000 still missing as of early December 2025.

These floods emerged amid a backdrop of climate-driven extremes, highlighting vulnerabilities in urban planning, watershed management, and disaster resilience across the region. Our webinar will explore what drove this event, the human and economic impacts as reflected in the latest data, and pathways for enhancing preparedness, early warning systems, and long-term resilience.

Why Attend?

This webinar will help you understand what happened, why it happened, and what it means for the future. You should join this webinar because it will provide:

• Authoritative analysis of the hydrometeorological conditions that triggered the floods, including extreme rainfall, land-use pressures, and climate-change influences.
• Country-by-country impacts (Indonesia, Sri Lanka, Thailand), offering a clear picture of human losses, economic damages, and infrastructure disruptions across the region.
• Expert insights on early warning, preparedness, and flood management, highlighting what worked, what failed, and what must change.
• Forward-looking perspectives, including how countries can strengthen resilience, adapt to accelerating climate extremes, and better manage transboundary water challenges.
• Lessons relevant worldwide, not only for Southeast Asia-urban planners, engineers, policymakers, and disaster-risk professionals everywhere can learn from these events.

Whether your interest is scientific, professional, humanitarian, or simply informed citizenship, this webinar will give you a deeper, evidence-based understanding of one of the year's most significant flood disasters-and practical guidance for improving resilience in your own context.
