The desert truffle is of great cultural, economical and ecological value. Desert truffles have been used for food and medicine since memorial times and the desert truffles are exported, generally to the Middle East. High international demand has led to increasing harvesting pressure. Desert truffles are very important to combat desertification. However production is rapidly decreasing by overexploitation (poor regulation and wrong harvest methods), desertification, damage by increasing number of cattle and climate changes.
Establishment of a sustainable agro-industry for desert truffles and gourmet truffles will supply high value food , promote rural development, provide income, restore degraded areas, and incorporate traditional knowledge. The goal of the meeting is to discuss the possibilities to valorize the desert truffle (terfess) in order to develop a sustainable chain.
