Huge Swath of Louisiana Wetlands Will Inevitably “Drown"...
A scientist, Harry Roberts, has made an alarming prediction that huge swaths of Louisiana wetlands will inevitably "drown" by the year 2100. A combination of rising ocean levels and lessening of silt from the Mississippi and Atchafalaya Rivers is expected to result in the inundation of large areas of Louisiana wetlands.
Engineering works on the Mississippi and Atchafalaya Rivers including dams and dikes have served to starve the wetlands from periodic replenishment of sediments.
In the study, published in Nature Geoscience, lead researcher Harry Roberts argues that Louisiana officials are going to have to triage. He says officials would have to choose which parts of the landscape could be saved and which must be abandoned, and to acknowledge that lives and businesses would be disrupted. Instead of breaking levees far south of New Orleans, where relatively few people live, Dr. Roberts said, officials should consider diversions much closer to New Orleans…. “It’s going to be an excruciating process to decide where that occurs,” Dr. Roberts said [The New York Times].
Whatever methods are used to try to mitigate the changes, it will be sure to be disruptive to human activities in the area.
