Track 1: Effects of Climate Change in Warm Weather Coastal Regions
The Third System of American fortification was the first cohesive network of military protection for the United States. From 1816 to 1867, 42 all-masonry forts were built to protect America’s major ports and coastal cities. New Orleans, highly valued due to its position at the mouth of the Mississippi River, received more protection than any other city: five forts and three subsidiary structures. This presentation examines the threat of sea level rise and land subsidence to the preservation of Third System forts in Louisiana by analyzing past and present environmental damage to the forts and subsidiary structures, natural and anthropogenic causes of relative sea level rise, methods of climate change mitigation currently in place there, and why environmental conservation is the best path to the structures’ long term preservation.
