The Five Rivers Alliance

About the team

The Five Rivers Alliance is a multidisciplinary team bringing together expertise from multiple environmental science fields. The team’s goal is to leverage the region’s natural strengths to develop nature-based solutions that work alongside existing industries, improving environmental conditions and community well-being. Through these solutions, the team also seeks to promote socio-environmental transformation by fostering sustainable economic activities, supporting resilience, and creating long-term opportunities for local communities.

Our vision

By 2120, the Mississippi River Delta evolves into a globally recognized model of nature-positive transformation by aligning human systems with the Delta’s ecological dynamics rather than resisting them. Sediment diversions rebuild land naturally, while wetlands, floodplains, and hybrid “living infrastructure” replace rigid gray defenses. Levees are retrofitted to work with restored marshes and floodable landscapes, allowing water to move, deposit sediment, and regenerate elevation. Industrial and energy systems are redesigned around circular, regenerative principles. Bio-refinery hubs are embedded within existing corridors and port networks, minimizing land fragmentation while converting excess nutrients and biomass into renewable energy. Delta ports shift toward electrified and hydrogen-supported logistics, powered in part by locally produced biofuels. Elevated community clusters reduce flood risk while concentrating housing, services, and renewable microgrids in compact, resilient settlements. Social and economic justice is foundational. Community-led co-management governs biomass harvesting and wetland restoration, ensuring equitable benefit-sharing. Workforce transition programs retrain workers from extractive sectors into restoration, monitoring, and renewable energy careers. Ecosystem service markets channel revenues into locally governed adaptation funds, prioritizing vulnerable communities and preserving cultural landscapes and fishing traditions. In Cocodrie, within the Terrebonne Basin, this transformation becomes tangible. Shallow bays and marsh-to-bay channels support nutrient capture, controlled biomass production, and real-time ecological monitoring. Partnerships with institutions such as Coastal Protection and Restoration Authority, National Oceanic and Atmospheric Administration, United States Geological Survey, and Louisiana State University Coastal Studies Institute ensure science-based implementation. The result is a resilient socio-ecological system where sediment builds land, nutrients fuel circular economies, oxygen-rich waters sustain fisheries, and communities thrive within dynamic landscapes—turning climate vulnerability into long-term ecological regeneration, economic opportunity, and environmental justice.

Our inventory & analysis

The selected site in Cocodrie, located within Louisiana’s Terrebonne Basin, represents a highly dynamic estuarine system shaped by the interaction of Mississippi River freshwater and Gulf marine conditions. This freshwater–saltwater interface generates nutrient-rich waters that support high biological productivity, particularly in shallow bays with relatively calm hydrodynamics. Extensive marshes act as natural buffers, regulating sediment transport, nutrient fluxes, and storm impacts. However, the area faces critical challenges, including marsh loss, erosion, declining water quality, hypoxia, and increasing climate vulnerability. The local economy depends heavily on fisheries, shrimping, oystering, and maritime industries, all of which are directly affected by ecosystem degradation and unstable environmental conditions. At the same time, Cocodrie benefits from strong scientific infrastructure, including long-term monitoring programs and nearby research institutions such as the Coastal Protection and Restoration Authority, National Oceanic and Atmospheric Administration, United States Geological Survey, and the Louisiana State University Coastal Studies Institute. Overall, the inventory reveals a landscape of high ecological productivity but significant environmental stress, supported by existing scientific capacity and maritime infrastructure. This combination positions Cocodrie as both vulnerable and uniquely suitable for regenerative, nature-based interventions.
