U006:
Coastal Louisiana: Canary in the Coal Mine for Low-Elevation Coastal Zones





Session ID#: 24115

Session Description:
The Mississippi Delta and surrounding areas host environmentally and economically critical ecosystems, high-value infrastructure associated with major port and industrial activities, and a unique cultural landscape. This region has suffered some of the world’s highest rates of wetland loss, major damage from tropical cyclones, and is facing rates of relative sea-level rise about four times the global average. These environmental conditions foreshadow impacts that can be expected in low-elevation coastal zones worldwide later this century with continued acceleration of sea-level rise. This session will bring together leading experts on sea-level rise, subsidence, sediment deficits, coastal storm risk, ecosystem degradation, plus the human dimension of rapid environmental change. These presentations will highlight the problems that coastal Louisiana is facing as well as the policy solutions (e.g., coastal restoration) that are currently on the table. The session looks toward the future and examines lessons that are relevant to low-elevation coastal zones globally.
