The municipality of Muzzana del Turgnano is the owner of the biggest lowland wood in the territory of the Friuli Venezia Giulia region, where the highly esteemed white truffle Tuber Magnatum Pico is found. This truffle received the first world certification for a truffle grown in a certified PEFC wood in 2011. The applicant, acting on behalf of the Municipality, wants to promote a twinning with the Municipality of Oprtalj, given that it is the owner of a centuries-old wood where similarly grows the white truffle. The twinning will be celebrated through a convention on the conservation and valorisation of woods in the days of the Truffle Fair in Muzzana, in its 4th year. During the envisaged event, each partner will present to the other its own situation and future actions plans and M.A.T. will share with the Croatian partner its experience in the PEFC certification. So, the aim of the project is to promote an exchange of ideas and concrete ongoing activities in order to enhance the conservation and the sustainable development of this fragile environment. Truffles are becoming scarcer and some scientists say it is because of the effects of global climate change and growing industrialization. The partners will also deepen the possibilities that the European Commission offers about the environmental conservation of local biodiversity in view of a wider networking of partners involved in future large-scale effort projects. The final objective it’s a common work protocol for truffles and their habitat. The convention will be composed by four reports, two of them of scientific subject, one relating to the best practise about certification of woods and the last one illustrating the EU funding opportunities. In addition, the fair will be the occasion to highlight remarkable affinities between local cooking traditions and the Croatian ones and to visit the Muzzana’s wood, so pointing out common history and culture and fostering a constructive dialogue.
