Proposed Mississippi River diversions—designed to increase wetland acreage on the Louisiana coast—must secure federal, state, and local government approvals and withstand possible legal challenges.
- Diversions will have potentially broad ecological and social effects across a large geographic area.
- The report describes regulatory and budgetary review processes for diversion projects, issues that slow approval, and ways to accelerate decisions.
- The approval process will have to resolve conflicts between proponents and opponents of such projects.
- Approval will hinge on model prediction uncertainty and the role of adaptive management, baseline conditions for assessing ecological and socioeconomic effects, and the potential to mitigate adverse consequences.
