LSU Report Underscores Regional Economic Costs of Coastal Land Loss

Study shows potential job growth, economic gains from implementing state’s Coastal Master Plan

BATON ROUGE – If the state takes no action to curb its coastal land loss crisis, Louisiana could lose as much as $3.6 billion in homes, businesses and other infrastructure over the next 50 years, according to a new study by the LSU Economics & Policy Research Group. The study projects additional economic losses of $7.6 billion in lost wages, consumer spending and supply chain disruptions that could “spread throughout the nation due to the state’s importance in shipping, energy production, chemicals and other sectors.”

The continued loss of Louisiana’s coastal wetlands could also mean far greater damages to the state further inland when major storms strike the coast. The report identifies damages in the form of lost businesses, residential and infrastructure assets that could increase by as much as $138 billion from a single major storm in a future without action to curb the state’s coastal land loss. The study outlines potential economic losses for the five most vulnerable regions of Louisiana – New Orleans, Baton Rouge, Houma, Lake Charles and Lafayette – which could face increased disruption costs if the state takes no action to restore the coast.

But the study also found cause for optimism. Investing in coastal protection and restoration projects would not only help protect existing coastal communities and infrastructure, but it will also support up to 10,500 jobs per year and generate as much as $1.5 billion in additional annual economic output for the state.
