(Comacchio, 21 May 14) The documentary "L'oro bianco" was produced to enhance and promote the Italian and Slovenian salt marshes in the SALTWORKS project: Cervia, Comacchio, Sicciole and Strugnano. Analysing the history, environmental and production features of each of the involved sites, the documentary aims to disseminate information on the naturalistic, cultural and historical values of the salt marshes as areas which today, thanks to the many initiatives and large-scale structural interventions, have become privileged destinations for eco-sustainable tourism.
