An energy analysis was used to estimate nonmarket values under various land
cover scenarios in the Mississippi Delta. Land loss since 1900 has led to
a decline in nonmarket values from $3.1 billion/year in 1900 to $2.5 billio
n in 1990, resulting in a total loss of $29.4 billion, This loss is concent
rated in the Barataria-Terrebonne basins, where nonmarket value has dropped
from $1.6 billion/year in 1956 to $1.3 billion/year in 1988. Although valu
es are projected to increase in the Atchafalaya basin (from $723 million/ye
ar in 1988 to $756 million/year in 2058), total nonmarket value for the Lou
isiana coast is projected to decrease to $2.1 billion/year under currently
approved levels of restoration.
