The general guidelines for sustainable collection are harvesting the plant in autumn to obtain the highest concentration of arbutin, gathering on southern slopes without a shadow tree, cutting only a partial portion of stem and leaves (≤ 25% of total biomass), and harvesting the same population only after three to four years after the previous harvest.

Among other non-wood forest products, MAPs are considered a key element of sustainable forest management and economic development. As part of Mediterranean cultural heritage, these plants are a major driver of rural tourism, in many areas representing an important raw material for various bio-based industrial sectors. Besides their economic value, MAPs enhance social integration and maintain gender balance as harvesting and processing MAPs is clearly a female dominated task. Despite the prominent contribution of MAPs to local development, conservation of biodiversity and the development of the traditional Mediterranean food system, many challenges and knowledge gaps could potentially place the sector’s development at risk. The aim of this work is to examine the present situation of the MAPs sector in the most productive countries around the Mediterranean and to ...

An example is the sustainable production of arnica in the Catalan Pyrenees. During 2009, an assessment of the potential production of arnica was conducted in the buffer area of the Aigüestortes and Estany de Sant Maurici National Park, where the species grows naturally and is used in folk medicine by local inhabitants. In order to develop a related economic activity in this area, the best adaptable production system was analyzed, considering two options a priori: sustainable wild harvesting and cultivation. Their potentialities and limitations were examined: resource density in the wild (flowering plants/ha), current demand of arnica flower heads in the national market, legal constraints, cultivation requirements and socio-economy of the area. In the studied area, wild collection of arnica flower heads must be ruled out, due to the obtained low estimated yield (70.5 g/ha of dry flower heads) when the recommended sustainable wild harvesting methods were followed. However, organic cultivation of local genotypes at an artisanal scale is encouraged, due to the relatively low demand of arnica in the Spanish market (1266 kg of dried flower heads/year), the current agriculture production system in the area (livestock pasturages and home-gardens) and the good germination rate and quality of local genotype.

It is one of 15 Future Harvest Centres supported by the Consultative Group on International Agricultural Research (CGIAR), an association of public and private members who support efforts to mobilize cutting-edge science to reduce hunger and poverty, improve human nutrition and health, and protect the environment. IPGRI has its headquarters in Maccarese, near Rome, Italy, with offices in more than 20 other countries worldwide. The Institute operates through three programmes: (1) the Plant Genetic Resources Programme, (2) the CGIAR Genetic Resources Support Programme and (3) the International Network for the Improvement of Banana and Plantain (INIBAP). The international status of IPGRI is conferred under an Establishment Agreement which, by January 2003, had been signed by the Governments of Algeria,
