Oyster Production in Barataria-Terrebonne National Estuary: Coastal Erosion in LA Travis Warziniack UT Economics

Background GIS in Economics (travel costs) Natural Production Functions Louisiana Coastal Erosion

Size of the Problem Louisiana contains 35% of nation’s wetlands LA has lost 30% since 1900 Another 80% will be lost by 2083 $3 billion in estimated projects Source: U.S. Geological Survey

Problems to Oyster Production Leases Oyster leases are given by geographic location Salinity Oyster Harvest = f(salinity, ..) Salt water encroachment As coastline moves in/out salt water advances/retreats inland

Barataria-Terrebonne National Estuary

Selected Gauging Stations Quad 43 79 Leases (3-939 acres)

Low Salinity

High Salinity – open to predators and disease

Estuary Salinity Levels Low Good High

Eye to the Future Missing Piece - Leases Future Monitoring Data and projects don’t overlap Implications Oystermen: which leases will be useless Policy: can measure the FULL costs
