Nautical Tourism, Carrying Capacity and Environmental Externality in the Lagoon of Marano and Grado

Tourism and environmental preservation are often conflicting activities, mainly in areas such as coastal lagoons, where seaside mass-tourism comes into contact with a very sensitive ecological system. In this paper we deal with a classical problem of both environmental and tourism
economics, the internalization of environmental costs of tourism,
focusing on the nautical fruition of the Lagoon of Marano and Grado
(North-Eastern Italy, Friuli Venezia Giulia Region).
Using different
instruments, both theoretical (Carrying Capacity framework,
Polluter-Payer principle, Coase compensation) and empirical (Cluster
analysis, Log-log regression, Forecasting model, cost and benefit
calculation through actual market values), we get the result that a
standard Coasian equilibrium (unit external cost equal to unit private
benefit) doesn’t hold, and a higher coverage of the local berths
endowment (i. e. a higher vessels transit in the Lagoon) is more
effective for nature conservation than a tempered fruition. Another
interesting result is that the best available solution to internalize
environmental externality is a mixed one, comprehensive of a command and
control rule (a speed-limit prescription), and a compensation scheme.
