Which region is predicted to face regular coastal flooding risk in the future?

• A. Southeast Asia
• B. United States
• C. Europe
• D. Australia

Answer: (A)

Rising sea levels combined with land subsidence in low-lying coastal areas drive increased coastal flooding. Southeast Asia stands out because it contains vast, low-lying river deltas and heavily populated coastal zones where land is often only a few meters above current sea level. In deltas like the Mekong, Red River, and Chao Phraya, large areas sit right at the water’s edge, making them highly vulnerable to higher seas. Added to this is subsidence from groundwater pumping and sediment compaction, which raises relative sea level and amplifies flood risk. With climate change, seas are projected to rise and storms to intensify, so many coastal communities in this region are expected to experience regular high-tide flooding and storm surge in the future.
