Cultivation of black truffle to promote reforestation and land-use stability

Cultivation of black truffle, Tuber melanosporum Vitt., has become an important agricultural alternative in rural Mediterranean regions due to its success in relatively harsh conditions, its high market value and diminishing production in natural areas. In addition, truffle cultivation requires relatively low agricultural inputs, promotes reforestation and economic restoration of rural lands and land-use stability. However, there remain major issues regarding the management practices to ensure successful black truffle production. We therefore conducted an experiment to evaluate 3 levels of irrigation based on monthly water deficit and the effects of currently applied weed control systems and fertilization. Treatment effects were evaluated by examining the mycorrhizal status of out-planted 1-yr-old Quercus ilex L. seedlings and seedling growth parameters after 18 months in 3 distinct experimental truffle plantations located in the foothills of the Spanish Pyrenees. We found that replacing one-half of the water deficit of the driest month (moderate irrigation) promoted the proliferation of T. melanosporum mycorrhizae, while high irrigation reduced fine root production and truffle mycorrhizae. Glyphosate weed control improved seedling survival by up to 16% over control seedlings without jeopardizing truffle mycorrhizae in the first year. Fertilization did not improve seedling growth or influence its mycorrhizal status. We describe the persistent relationship between this ectomycorrhizal fungus and Q. ilex by quantifying old and new mycorrhizae and we discuss the ecological implications of the symbiosis

Territorial Marketing Based on Non-Wood Forest Products (NWFPs) to Enhance Sustainable Tourism in Rural Areas: A Literature Review

It is often seen how a distinctive feature of a territory is used as a brand to create an image that attracts tourists to the region. This is so-called “territorial marketing”, and together with this brand, connected products and services, usually related to recreation, gastronomy and well-being, are offered. Non-wood forest products (NWFPs), such as mushrooms, truffles, aromatic and medicinal plants, nuts and berries, are natural products connected to local traditions that contribute to rural economies, culture and society. This becomes particularly prominent when used as elements of identity to brand specific geographical areas such as the “Chestnut Route”, the “Cranberry Valley” or the “Truffle Way”. This review aims to delve into the understanding of this link between NWFPs and sustainable tourism through territorial marketing and to discuss the different perspectives that address this field, including the methodologies used for the studies, as well as to identify the main research topics tackled in the literature, territorial marketing models and the challenges for its development. The results show the multidisciplinary nature of this field of research, addressed primarily by economists through qualitative surveys and case studies. Most authors emphasize the growing interest in territorial marketing in rural areas as well as the importance of involving the local population in the implementation process. Several studies offer a territorial marketing process model, among which stakeholders’ participation, place identity and image, as well as their interaction, are main aspects to be considered when developing this strategy. A new territorial marketing model is proposed. While it is an emergent research field, studies focused on territorial marketing based on NWFPs to attract tourism remain a research niche.This research was developed within the framework of the WILDFOOD Project “Eating the Wild: Improving the Value-Chain of Mediterranean Wild Food Products” funded by the Partnership for Research and Innovation in the Mediterranean Area (PRIMA) and the National Funding Agencies (PRIMA Call 2019, Section 2; reference number: PCI2020-112020)
