Recreation Management in the Venice Lagoon: Methodological Aspects and Empirical Evaluation

By Edi Defrancesco and Paolo Rosato

ABSTRACT

The Venice lagoon is the largest lagoon in the Mediterranean sea (550 km2). It is a relevant site for both professional fishing and recreation (fishing and boating). The paper analyses the recreational and sport-fishing demand using contingent valuation and travel cost method.

A stratified sample-based survey has been made in order to:
  • quantify and describe the users
  • estimate the demand function of every users' typology
  • estimate the total annual recreational use value of the lagoon
  • simulate potential financing by users aimed to improve conservation management.
From a methodological point of view, the individual travel cost method has been adjusted for taking into account the boat's fixed cost (considered as sunk cost).

Main results:
  • the survey has shown that around 13,000 users per year can be estimated (77% boating, and 23% fishing); the average number of yearly visit per user is approximately 25
  • the demand functions resulting from adjusted travel cost method and contingent valuation one are similar
  • the total recreational surplus significantly differs both between fishing and boating users, and between users living in Venice island (24%) and in mainland (76%
  • the simulations of management policies financing conservation measures have been evaluated from welfare and financial point of view.

Different taxation policies have been considered. For example, a €31 per year payment could be charged on mainland-resident users without significantly reducing the total users' number. In conclusion, management policies have to take into account redistribution effects and property rights of island residents.
