Application of Pastoralists\u27 Knowledge to Natural Resource Management in Spain

Extensive livestock rearing has been acknowledged as an important tool for sustainable management of social-ecological systems and biodiversity conservation. In the Mediterranean Basin this relationship has been highlighted in mountainous and rural areas, where the co-evolved assemblages and dynamics of plant communities and grazing practices and patterns are mutually reinforcing. Among extensive livestock rearing systems, mobile pastoralism is a typical adaptation in semi-arid areas and mountainous regions where pasture availability is especially variable in time and space. In Spain, mobile pastoralism dates back to Neolithic and has survived until our days in different ways. An outstanding example of mobility is transhumance, an ancient pastoralist practice consisting of the seasonal migration of livestock between ecological regions following peaks in pasture productivity. Traditional ecological knowledge (TEK) can provide valuable information that complements scientific studies to improve understanding and stewardship of ecosystems. In particular, transhumance depends on the preservation, use, and transmission of TEK and the integration of TEK into land use and management policies. In this paper, we: (1) provide examples of traditional ecological knowledge related to extensive livestock rearing, and transhumance in particular, that could be useful for grasslands management; (2) explore the current challenges to the integration of this knowledge for Spanish grasslands’ management; and (3) provide insights on how these barriers might be overcome. The evidence is based on two case studies: one in the two westernmost central Pyrenean valleys of Ansó and Hecho (Aragón), where shepherds carry out short valley-mountain and middle-distance transhumance (ca. 200 km); and the other on the summer pasturelands of Montes Universales (Aragón, Guadalajara and Cuenca) from where a long-distance transhumance through the Conquense Drove Road departs (ca. 500 km). In-depth semi-structured interviews, focus groups and participant observation where applied in both cases. We conclude that much of mobile extensive stockmen’s ecological knowledge is threaten due to a lack of generational turnover, endangering the survival of a valuable source of sustainable grassland management knowledge and practices. Social and institutional barriers, including lack of profitability, dependence on EU subsidies, competition with other land-uses such as biodiversity conservation or hunting, and neglect by governments and society, negatively affect the continuity of TEK at different scales. However, some strategies, such as pastoralists’ cooperation in making their voices heard in regional and European policy decisions, or their involvement in monitoring ecological conditions of ecosystems, may foster a modest recovery of transhumance in Spain

"Tertius gaudens" : germplasm exchange networks and agroecological knowledge among home gardeners in the Iberian Peninsula

Background: The idea that knowledge flows through social networks is implicit in research on traditional knowledge, but researchers have paid scant attention to the role of social networks in shaping its distribution. We bridge those two bodies of research and investigate a) the structure of network of exchange of plant propagation material (germplasm) and b) the relation between a person's centrality in such network and his/her agroecological knowledge. Methods: We study 10 networks of germplasm exchange (n = 363) in mountain regions of the Iberian Peninsula. Data were collected through participant observation, semi-structured interviews, and a survey. Results: The networks display some structural characteristics (i.e., decentralization, presence of external actors) that could enhance the flow of knowledge and germplasm but also some characteristics that do not favor such flow (i.e., low density and fragmentation). We also find that a measure that captures the number of contacts of an individual in the germplasm exchange network is associated with the person's agroecological knowledge. Conclusion: Our findings highlight the importance of social relations in the construction of traditional knowledge

Traditional ecological knowledge among transhumant pastoralists in Mediterranean Spain

Mobility is a millenary human strategy to deal with environmental change. An outstanding example of mobility is transhumance, an ancient pastoralist practice consisting of the seasonal migration of livestock between ecological regions following peaks in pasture productivity. The maintenance of transhumance depends partly on the preservation of related traditional ecological knowledge (TEK). We (a) identified and characterized social groups that hold transhumance-related TEK, (b) analyzed trends in transhumance-related TEK across generations and social groups, (c) examined the factors that influence variation in levels of TEK, and (d) analyzed elements of transhumance-related TEK as examples of adaptive strategies to cope with global change. We used transhumance on the Conquense Drove Road, a major active transhumant network in Spain, as a case study. Through an indepth literature review, participant observation, semistructured interviews, and a focus group discussion, we developed a survey to examine transhumance-related knowledge, practices, and beliefs. We collected survey data from 150 informants. Although a rich body of TEK persisted among transhumant shepherds, we found a marked loss of TEK among transhumants born after 1975, who scored one-fifth lower on survey items than other generations. The maintenance of transhumance on foot is the most important factor influencing TEK preservation. We conclude that in developed country settings, maintaining conditions for herd mobility can contribute to enhancing the adaptive capacity of agrarian societies to cope with global environmental change

Resilience of traditional knowledge systems: The case of agricultural knowledge in home gardens of the Iberian Peninsula

34 pág., 1 mapa, gráf.The resilience of a social–ecological system largely depends on its capacity to learn by absorbing new information to cope with change. But, how resilient are traditional knowledge systems? We explore the resilience of the traditional agricultural knowledge system of home gardeners in the Iberian Peninsula (n = 383). We use multivariate analysis to explore the co-existence of agricultural information derived from two different knowledge systems: (i) knowledge and use of landraces (representative of traditional agricultural knowledge) and (ii) knowledge and use of commercial crop varieties (representative of modern agricultural knowledge). Our analyses show a positive association between both types of knowledge: overall gardeners who are more knowledgeable about commercial crop varieties are also more knowledgeable about landraces. Despite this overall tendency, results from hierarchical cluster analysis showed different groups of traditional and modern knowledge holders. Our results suggest that (a) traditional knowledge is not a frozen and static corpus of knowledge and (b) modern and traditional agricultural knowledge are not necessarily mutually exclusive. Both maintenance of some aspects of the traditional knowledge and incorporation of some aspect of the modern knowledge seem to be core elements of home gardeners’ body of agricultural knowledge which is constantly evolving in response to changing environmental and socioeconomic conditions. Changes in traditional knowledge can be seen as a part of the general self-organizing process of this knowledge system.Research was funded by the Programa de Ciencias Sociales y Humanidades del Ministerio de Educación y Ciencia (Spain) (SEJ2007-60873/SOCI and CSO2011-27565).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

Las plantas medicinales en el inventario español sobre los conocimientos Tradicionales relativos al patrimonio natural y a la biodiversidad

En las últimas décadas las organizaciones internacionales han puesto de manifiesto la importancia de los conocimientos ecológicos tradicionales para la conservación y el uso sostenible de la diversidad biológica, como se refleja en el Convenio sobre la Diversidad Biológica (CBD 1992). En España, el marco jurídico que recoge las normas y recomendaciones de esta estrategia es la Ley de Patrimonio Natural y Biodiveresidad 42/2007 que establece la creación del Inventario Español de Conocimientos Tradicionales (IECT) relevantes para la conservación y el uso sostenible de la biodiversidad y geodiversidad. Desde hace más de un año un equipo de más de 60 investigadores, incluyendo botánicos, zoólogos, antropólogos, ecólogos y geólogos de más de 20 centros de investigación y universidades del estado español, están trabajando en el IEDT, con el objetivo de recopilar y difundir la información publicada sobre los conocimientos tradicionales relativos a la flora, fauna, geodiversidad y el manejo de los ecosistemas

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
