The human interventions intended to make Louisiana's coastline habitable and productive over the past century have contributed to the region's most existential threats. Without redress, displaced river sediment, compromised wetlands, and land subsidence will increasingly expose the state to extreme storm surge and sea level rise.
In 2007, following the devastating impacts of Hurricanes Katrina and Rita, Louisiana adopted its Coastal Master Plan. More than 100 projects have been approved under the plan, including the $3 billion Mid Barataria Sediment Diversion. The largest project of its kind, the diversion was designed to regenerate 40 square miles of barrier wetlands by allowing the leveed river to flood the Barataria Basin. Construction began in 2023, but it was ultimately canceled by Governor Jeff Landry in July of 2025 due to financial and environmental objections.
The arc of this project, from its design through its cancellation, exemplifies how complicated and divisive collective decision-making can become in the age of climate change. Projects scaled to meet major resilience issues are rarely able to serve the conflicting priorities, values, and interests of all stakeholders equally—and trade-offs can bring conflict at every step.
The Water Institute CEO Beaux Jones and award-winning environmental journalist Boyce Upholt both return to the podcast—this time for a joint conversation about the dilemmas in Mississippi River management, conflicting interests and negotiations in coastal resilience, and what it all means for Louisiana’s future.
