As many of tribal communities are in coastal areas and depend on the swamps and bayous as a source of food and economic resource, they have been severely and adversely affected by the continuing coastal erosion and loss of wetlands. Different factors associated with industrialization have contributed to such losses, including dredging of navigation canals by shipping and oil companies, which increased water movement and erosion, increasing salt water intrusion and causing loss of wetlands plants. In addition, oil companies have buried piping under the ground but not covered it sufficiently.
The community of Isle de Jean Charles has suffered severe erosion; scientists estimate that the island will be lost by 2030 if no restoration takes place. The Houma tribe is looking for land in the area to buy in order to resettle all of the community together. Coastal erosion has adversely affected the quality of fishing. The tribe has suffered from a decrease in fish, as saltwater intrusion has destroyed many of the old fishing holes.*
