Conocimientos tradicionales relativos a la biodiversidad agrícola

La biodiversidad agrícola, a diferencia de la silvestre, requiere la acción continuada de los agricultores para su conservación, ya que las plantas cultivadas dependen de la intervención humana, con actividades como la selección, la siembra, el abonado, la poda u otras prácticas agrícolas para su supervivencia. Desde la revolución agrícola del Neolítico hasta la actualidad, estas prácticas y conocimientos han ido generando y conservando una gran diversidad, amenazada a partir de la segunda mitad del siglo XX por las causas que se han indicado anteriormente.Peer reviewe

Sharing Plant Uses with Animals: Plants Used for Feeding and Curing Humans and Animals in the Spanish Inventory of Traditional Knowledge Related to Biodiversity

Trabajo presentado en la 57th Annual Meeting of the Society for Economic Botany (Cultural resilience and resource extraction: preserving plants & people of degraded ecosystems), celebrada en Pine Mountain (USA) del 5 al 9 de junio de 2016.Spain has a very rich and dynamic traditional ecological knowledge system that has suffered severe erosion over the last decades. This knowledge has been deeply influenced by a rich and diverse historical heritage that includes many centuries old documents from ancient cultures, some over 2000 years old. Spanish acute useful flora comprises around 3,000 species, most of them autochthonous. A team of more than 70 scientists from more than 30 universities and other research centres are developing the Spanish Inventory of Traditional Knowledge. The inventory includes a database with information from over180 papers. The review of such papers showed that more than 2,300 plant species are used in human and animal food and medicine: 1,681 in human medicine, 1,295 in animal food, 953 in human food and 709 in veterinary medicine. Nearly 14% of the species (313) are shared in the four categories and a very important amount of species are used both for humans and animals: 35% of the species (800) are employed in animal food and medicine, 31% (710) in human food and medicine, 28% (650) in human and veterinary medicine and 27% (624) in animal and human food. This high percentage of overlap between human and animal uses may indicate that the observation of animal behaviour , specially feeding and selfmedication behaviours, might have given clues to humans on how to use food and medicinal plants[Lo1]. It also reinforces the idea that food and medicine represent a continuum not only for humans, but also for animals.Peer reviewe

Sustainability of traditional ecological knowledge: importance, distribution, endemicity and conservation of Spanish medicinal plants

Trabajo presentado en la 58th Annual Meeting of the Society for Economic Botany (Living in a global world: local knowledge ans sustainability), celebrada en Braganza (Portugal) del 4 al 9 de junio de 2017.-- IECTB authors: L Aceituno, R Acosta, A Alvarez, E Barroso, J Blanco, MA Bonet, L Calvet, E Carrio, R Cavero, U DAmbrosio , L Delgado, J Fajardo, I Fernandez-Ordonez, J Garcia, T Garnatje, JA Gonzalez, R Gonzalez-Tejero, A Gras, E Hernandez-Bermejo, E Laguna, JA Latorre, C.

The Mediterranean basin, and specifically Spain, has a great floristic and ethnobotanical richness, comprising its useful flora around 3,000 plant species. This paper studies medicinal plants traditionally used in Spain in order to analyze the sustainability of their exploitation. Given that sustainability is related to the amount of the resource and its gathering pressure, its availability and cultural importance were analysed based on: the number of papers cited from a selection of over 180 papers, the number of 10x10 km UTM grid cells in which the plants were represented, the number of phytosociological inventories in which the presence of the plant has been registered, and searched on their current conservation status in European, national and regional legislations. The total number of wild or naturalized medicinal species in Spain reaches 1,393, 15% of them being endemic. A positive correlation was found among cultural importance and abundance (ρ=0.48) and among cultural importance and distribution (ρ=0.502), showing that abundant widely distributed species are those more commonly used. Most of the medicinal plants (72%) do not appear on the consulted regulations and do not have any legal protection or known threat and only 11 species are registered in any of the annexes of the European Habitats directive. While this study confirms that people tend to select as medicinal abundant and widely distributed species, many other criteria are used for selecting them.Peer reviewe
