    Disruption of traditional land use regimes causes an economic loss of provisioning services in high-mountain grasslands

    Mountain ecosystems face many challenges related to global change. Most high-altitude grasslands in the Pyrenees, despite representing valuable assets recognised in the European conservation heritage, are at risk due to the decline of traditional extensive ranging. This research intends to quantify economically the loss of the provisioning service of high-quality food for livestock of an upland area on the western side of the range. The area is experiencing degradation due to the expansion of the native tall-grass Brachypodium rupestre, favoured by disruption of traditional grazing and anthropogenic fire regimes. We implement the substitution economic approach and use floristic and husbandry data to determine that the loss of food rations for livestock results in an unitary cost of 107 (sic).ha(-1).year(-1), amounting to 21146 (sic) for the whole degraded area, according to the most conservative estimate. The study also finds evidence that the decline in grassland value is closely associated with the digestibility to herbivores of B. rupestre during the growing season. This approach may be an effective tool to raise awareness of the problem among local and regional stakeholders and encourage further environmental actions to prevent the degradation.

    Horse meat production in northern Spain: ecosystem services and sustainability in high nature value farmland
    (Oxford University Press, 2021) Insausti Barrenetxea, Kizkitza; Beldarrain, Lorea R.; Lavín, María Paz; Aldai Elkoro-Iribe, Noelia; Mantecón, Angel R.; Sáez Istilart, José Luis; Canals Tresserras, Rosa María; Institute on Innovation and Sustainable Development in Food Chain - ISFOOD
    -Pasture-based, extensive livestock systems play an im-portant role in the preservation of the rural landscape, and the many ecosystem services associated. -Spain is the major horse meat producer at EU level, based on traditional extensive systems and a subse-quent fattening outside the origin region. -The movement of animals from raising to fattening areas entails a loss of added value in the regions of ori-gin, which decreases farm profitability. -The social recognition of the environmental role of extensive rearing systems based on native breeds and the local production and valorization of the horse meat are crucial objectives that need to be addressed and developed in the following years.
