Louisiana breaks ground on experimental project to rebuild lost wetlands
Over thousands of years, the Mississippi River wended its way through the lush and dense wetlands of the Barataria Basin in what’s now south-central Louisiana. As it flowed south on its way to the sea, the river continually poured sediment into the basin, gifting it with fresh, nutrient-rich river mud that replenished the land and prevented coastal erosion. But 20th-century innovations like dams and levees stopped the river’s natural systems. This, in combination with recent sea-level rise and the constant battering of supercharged hurricane seasons, means the sea now gnaws steadily at the bottom of the state, causing gradual but catastrophic land loss. Since 1932, the Barataria has lost 17 percent of its land. It’s predicted to lose another 200-plus square miles in the next 20 years.
To combat this, Louisiana officials broke ground Thursday on an ambitious, $ 2.92 …
