Sediment Diversions: Big Projects Confront Land Loss in the Mississippi River Delta
The Mississippi River Delta and Louisiana coastline are disappearing. Since the late 1920s, efforts to control the Mississippi through levees and dams have impeded its natural ability to deposit sediment downstream, contributing to large-scale land loss. It’s estimated that Louisiana’s coastal parishes lost roughly two thousand square miles of land between 1932 and 2016. As rising seas driven by climate change threaten to further consume the Gulf coast, there is an imperative to address the growing problem of shrinking landmass. Confronting this threat with a sense of urgency will allow for preservation of Louisiana’s communities, economies, and cultural resources into the future.
