Description
Jiangbo Wang and Jiafeng Wu published a 2026 study of how population has shifted inside flood-prone parts of China's Pearl River Delta from 1985 to 2024. Most earlier work looked only at the 100-year flood, the event with a one percent yearly chance. The authors mapped six flood levels, from frequent 10-year events to a rare 1,000-year event, and matched them to population data and flood control upgrades.
Outside the mildest scenario, population grew fastest in the extreme high-risk zone, and growth inside risk zones outpaced the region as a whole. Eight cities besides Shenzhen showed the same pattern in high-risk areas. The authors argue that prevention planning should differ by city and flood level rather than treating the delta as uniform.
