It’s Sedimentary: Rethinking the Role of Mud
Sediment starvation is another slowly building crisis, but at least this one has more tractable solutions than Anthropogenic Global Warming (AGW) from Greenhouse Gases (GHG). Check out this piece in Yale Environment 360 that sketches out the problem and the solutions:
Sediment Loss and Restoration
As the article says, Southern Louisiana has lost 2,000 square miles of land and 20% of its wetlands since the 1930’s, when the Army Corps of Engineers set upon the Mississippi River with all the water-taming tools at its disposal. Throughout the world, 57,600 large dams and innumerable small ones are trapping sediment which would otherwise enrich downstream ecosystems.* Robin Grossinger of the San Francisco Estuary Institute likens it to “starving” the ecosystems of “nutrients, minerals, and vitamins [that] these systems need to grow and adapt.”*
Read the article in Yale Environment 360 linked above, for a look at ongoing and potential ways to redistribute trapped sediment, even without necessarily dismantling dams.
