Selection of the Most Suitable Tree Species for Truffle Cultivation Using Fuzzy VIKOR and Fuzzy AHP: New Paths in Forest Policy Planning

Truffle cultivation is considered to be a very profitable agricultural activity; it is however strongly demanding, with a highly uncertain yield. The selection of an appropriate site and host tree species is challenging, because truffles have very specific edaphoclimatic and topographic requirements. The aim of this article is to select the optimum tree species for truffle cultivation in Greece, by examining the most common host tree species under criteria that affect truffle productivity, thus pointing to new paths for forest policy planning. A combination of fuzzy AHP and fuzzy VIKOR was applied in two different scenarios, using equal and different criteria weights. Oak, hornbeam and pine trees were identified as the most suitable tree species for truffle cultivation in Greece. The findings could help mitigate uncertainty and improve productivity. They are also useful in Forest Policy planning, offering incentives for the reforestation of less favoured areas and the conversion of marginal or abandoned agricultural land.
