Louisiana is the most flood-prone state in the U.S. due to rising sea levels, land subsidence, and wetland loss.

Louisiana is highly vulnerable to flooding from rising sea levels, driven by climate change and subsidence, where the land gradually sinks. This state has a low-lying geography, with much of its coastal area sitting at or below sea level, making it particularly susceptible. The loss of wetlands, which naturally buffer against storm surges, exacerbates the issue. Additionally, hurricanes and tropical storms often bring heavy rains and storm surges, worsening flooding risks. Coastal cities like New Orleans face significant challenges in adapting to these changes, highlighting the urgent need for sustainable flood management and climate adaptation strategies.
