El sector ganadero est siendo gradualmente dominado por sistemas intensivos y especializados en los que los factores de produccin estn controlados y en los que los caracteres productivos son los criterios principales para la seleccin de especies y razas. Entretanto, muchos de los bienes y servicios que tradicionalmente suministraba el ganado, tales como los fertilizantes, la traccin animal o materias primas para la elaboracin vestimenta y calzado estn siendo reemplazados por productos industriales. Como consecuencia de ambos cambios, las razas seleccionadas intensivamente, las cuales estn estrechamente ligadas a sistemas agrcolas de alta produccin y altos insumos, han desplazado a muchas razas autctonas, en las que la seleccin prcticamente ha cesado o es muy poco intensa. Actualmente existe una mayor conciencia social sobre la situacin de las razas autctonas y muchas funciones del ganado que previamente haban sido ignoradas estn siendo reconocidas. Desde hace algunas dcadas, se ha aceptado internacionalmente que las razas de ganado cumplen funciones econmicas, socio-culturales, medioambientales y de seguridad alimentaria. Por ello, diferentes organismos internacionales han reconocido que la disminucin de los recursos genticos de animales domsticos (RGADs) es un problema grave y han recomendado su conservacin. Aun as, la conservacin de RGADs es un tema controvertido por la dificultad de valorar las funciones del ganado. Esta valoracin es compleja debido que los RGADs tiene una doble naturaleza privada - pblica. Como algunos economistas han subrayado, el ganado es un bien privado, sin embargo debido a algunas de sus funciones, tambin es un bien pblico. De esta forma, el aumento del conocimiento sobre valor de cada una de sus funciones facilitara la toma de decisiones en relacin a su conservacin y desarrollo. Sin embargo, esta valoracin es controvertida puesto que la importancia relativa de las funciones del ganado vara en funcin del momento, del lugar, de las especies y de las razas. El sector ganadero, debido a sus mltiples funciones, est influenciado por factores tcnicos, medioambientales, sociales, culturales y polticos que estn interrelacionados y que engloban a una enorme variedad de actores y procesos. Al igual que las funciones del ganado, los factores que afectan a su conservacin y desarrollo estn fuertemente condicionados por localizacin geogrfica. Asimismo, estos factores pueden ser muy heterogneos incluso dentro de una misma raza. Por otro lado, es razonable pensar que el ganadero es el actor principal de la conservacin de razas locales. Actualmente, las razas locales estn siendo Integration of socioeconomic and genetic aspects involved in the conservation of animal genetic resources 5 explotadas por ganaderos muy diversos bajo sistemas de produccin tambin muy diferentes. Por todo ello, es de vital importancia comprender y evaluar el impacto que tienen las motivaciones, y el proceso de toma de decisiones de los ganaderos en la estructura gentica de las razas. En esta tesis doctoral exploramos diferentes aspectos sociales, econmicos y genticos involucrados en la conservacin de razas locales de ganado vacuno en Europa, como ejemplo de RGADs, esperando contribuir al entendimiento cientfico de este complejo tema. Nuestro objetivo es conseguir una visin global de los procesos subyacentes en la conservacin y desarrollo de estas razas. Pretendemos ilustrar como se pueden utilizar mtodos cuantitativos en el diseo y establecimiento de estrategias de conservacin y desarrollo de RGADs objetivas y adecuadas. En primer lugar, exploramos el valor econmico total (VET) del ganado analizando sus componentes pblicos fuera de mercado usando como caso de estudio la raza vacuna Alistana-Sanabresa (AS). El VET de cualquier bien est formado por componentes de uso y de no-uso. Estos ltimos incluyen el valor de opcin, el valor de herencia y el valor de existencia. En el caso del ganado local, el valor de uso directo proviene de sus productos. Los valores de uso indirecto estn relacionados con el papel que cumple las razas en el mantenimiento de los paisajes y cultura rural. El valor de opcin se refiere a su futuro uso potencial y el valor de herencia al uso potencial de las generaciones venideras. Finalmente, el valor de existencia est relacionado con el bienestar que produce a la gente saber que existe un recurso especfico. Nuestro objetivo fue determinar la importancia relativa que tienen los componentes fuera de mercado sobre el VET de la raza AS. Para ello evaluamos la voluntad de la gente a pagar por la conservacin de la AS mediante experimentos de eleccin (EEs) a travs de encuestas. Estos experimentos permiten valorar individualmente los distintos componentes del VET de cualquier bien. Los resultados los analizamos mediante de uso de modelos aleatorios logit. Encontramos que las funciones pblicas de la raza AS tienen un valor significativo. Sus valores ms importantes son el valor de uso indirecto como elemento cultural Zamorano y el valor de existencia (ambos representaron el 80% de VET). Adems observamos que el valor que gente da a las funciones pblicas de la razas de ganado dependen de sus caractersticas socioeconmicas. Los factores que condicionaron la voluntad a pagar para la conservacin de la raza AS fueron el lugar de residencia (ciudad o pueblo), el haber visto animales de la raza o haber consumido sus productos y la actitud de los encuestados ante los conflictos entre el desarrollo econmico y el medioambiente. Por otro lado, encontramos que no todo el mundo tiene una visin completa e integrada de todas las funciones pblicas de la raza AS. Por este motivo, los programas o actividades de concienciacin sobre su estado deberan hacer hincapi en este aspecto. La existencia de valores pblicos de la raza AS implica que los ganaderos deberan recibir compensaciones econmicas como pago por las funciones pblicas que cumple su raza local. Las compensaciones aseguraran un tamao de poblacin que permitira que la raza AS siga realizando estas funciones. Un mecanismo para ello podra ser el desarrollo del turismo rural relacionado con la raza. Esto aumentara el valor de uso privado mientras que supondra un elemento aadido a las estrategias de conservacin y desarrollo. No obstante, los ganaderos deben analizar cmo aprovechar los nichos de mercado existentes, as como mejorar la calidad de los productos de la raza prestando especial atencin al etiquetado de los mismos. Una vez evaluada la importancia de las funciones pblicas de las razas locales de ganado, analizamos la diversidad de factores tcnicos, econmicos y sociales de la produccin de razas locales de ganado vacuno existente en Europa. Con este fin analizamos el caso de quince razas locales de ocho pases en el contexto de un proyecto de colaboracin internacional. Investigamos las diferencias entre los pases para determinar los factores comunes clave que afectan a la viabilidad de las razas locales. Para ello entrevistamos mediante cuestionarios a un total de 355 ganaderos en las quince razas. Como indicador de viabilidad usamos los planes de los ganaderos de variacin del tamao de las ganaderas. Los cuestionarios incluan diferentes aspectos econmicos, tcnicos y sociales con potencial influencia en las dinmicas demogrficas de las razas locales. Los datos recogidos los analizamos mediante distintas tcnicas estadsticas multivariantes como el anlisis discriminante y la regresin logstica. Encontramos que los factores que afectan a la viabilidad de las razas locales en Europa son muy heterogneos. Un resultado reseable fue que los ganaderos de algunos pases no consideran que la explotacin de su raza tenga un alto valor social. Este hecho vuelve a poner de manifiesto la importancia de desarrollar programas Europeos de concienciacin sobre la importancia de las funciones que cumplen las razas locales. Adems los pases analizados presentaron una alta variabilidad en cuanto a la importancia de los mercados locales en la distribucin de los productos y en cuanto al porcentaje en propiedad del total de los pastos usados en las explotaciones. Este estudio reflej la variabilidad de los sistemas y medios de produccin (en el sentido socioeconmico, tcnico y ecolgico) que existe en Europa. Por ello hay que ser cautos en la implementacin de las polticas comunes en los diferentes pases. Tambin encontramos que la variabilidad dentro de los pases puede ser elevada debido a las diferencias entre razas, lo que implica que las polticas nacionales deber ser suficientemente flexibles para adaptarse a las peculiaridades de cada una de las razas. Por otro lado, encontramos una serie de factores comunes a la viabilidad de las razas en los distintos pases; la edad de los ganaderos, la colaboracin entre ellos y la apreciacin social de las funciones culturales, medioambientales y sociales del ganado local. El envejecimiento de los ganaderos de razas locales no es solo un problema de falta de transferencia generacional, sino que tambin puede suponer una actitud ms negativa hacia la inversin en las actividades ganaderas y en una menor capacidad de adaptacin a los cambios del sector. La capacidad de adaptacin de los ganaderos es un factor crucial en la viabilidad de las razas locales. Las estrategias y polticas de conservacin comunes deben incluir las variables comunes a la viabilidad de las razas manteniendo flexibilidad suficiente para adaptarse a las especificidades nacionales. Estas estrategias y polticas deberan ir ms all de compensacin econmica a los ganaderos de razas locales por la menor productividad de sus razas. Las herramientas para la toma de decisiones ayudan a generar una visin amplia de la conservacin y desarrollo de las razas locales. Estas herramientas abordan el diseo de estrategias de conservacin y desarrollo de forma sistemtica y estructurada. En la tercera parte de la tesis usamos una de estas herramientas, el anlisis DAFO (Debilidades, Amenazas, Fortalezas y Oportunidades), con este propsito, reconociendo que la conservacin de RGADs depende de los ganaderos. Desarrollamos un anlisis DAFO cuantitativo y lo aplicamos a trece razas locales de ganado vacuno de seis pases europeos en el contexto del proyecto de colaboracin mencionado anteriormente. El mtodo tiene cuatro pasos: 1) la definicin del sistema; 2) la identificacin y agrupacin de los factores influyentes; 3) la cuantificacin de la importancia de dichos factores y 4) la identificacin y priorizacin de estrategias. Identificamos los factores utilizando multitud de agentes (multi-stakeholder appproach). Una vez determinados los factores se agruparon en una estructura de tres niveles. La importancia relativa de los cada uno de los factores para cada raza fue determinada por grupos de expertos en RGADs de los pases integrados en el citado proyecto. Finalmente, desarrollamos un proceso de cuantificacin para identificar y priorizar estrategias. La estructura de agrupacin de factores permiti analizar el problema de la conservacin desde el nivel general hasta el concreto. La unin de anlisis especficos de cada una de las razas en un anlisis DAFO comn permiti evaluar la adecuacin de las estrategias a cada caso concreto. Identificamos un total de 99 factores. El anlisis revel que mientras los factores menos importantes son muy consistentes entre razas, los factores y estrategias ms relevantes son muy heterogneos. La idoneidad de las estrategias fue mayor a medida que estas se hacan ms generales. A pesar de dicha heterogeneidad, los factores influyentes y estrategias ms importantes estaban ligados a aspectos positivos (fortalezas y oportunidades) lo que implica que el futuro de estas razas es prometedor. Los resultados de nuestro anlisis tambin confirmaron la gran relevancia del valor cultural de estas razas. Las factores internos (fortalezas y debilidades) ms importantes estaban relacionadas con los sistemas de produccin y los ganaderos. Las oportunidades ms relevantes estaban relacionadas con el desarrollo y marketing de nuevos productos mientras que las amenazas ms importantes se encontraron a la hora de vender los productos actuales. Este resultado implica que sera fructfero trabajar en la motivacin y colaboracin entre ganaderos as como, en la mejora de sus capacidades. Concluimos que las polticas comunes europeas deberan centrarse en aspectos generales y ser los suficientemente flexibles para adaptarse a las singularidades de los pases y las razas. Como ya se ha mencionado, los ganaderos juegan un papel esencial en la conservacin y desarrollo de las razas autctonas. Por ello es relevante entender que implicacin puede tener la heterogeneidad de los mismos en la viabilidad de una raza. En la cuarta parte de la tesis hemos identificado tipos de ganaderos con el fin de entender cmo la relacin entre la variabilidad de sus caractersticas socioeconmicas, los perfiles de las ganaderas y las dinmicas de las mismas. El anlisis se ha realizado en un contexto sociolgico, aplicando los conceptos de capital cultural y econmico. Las tipologas se han determinado en funcin de factores socioeconmicos y culturales indicadores del capital cultural y capital econmico de un individuo. Nuestro objetivo era estudiar si la tipologa socioeconmica de los ganaderos afecta al perfil de su ganadera y a las decisiones que toman. Entrevistamos a 85 ganaderos de la raza Avilea-Negra Ibrica (ANI) y utilizamos los resultados de dichas entrevistas para ilustrar y testar el proceso. Definimos los tipos de ganaderos utilizando un anlisis de clster jerarquizado con un grupo de variables cannicas que se obtuvieron en funcin de cinco factores socioeconmicos: el nivel de educacin del ganadero, el ao en que empez a ser ganadero de ANI, el porcentaje de los ingresos familiares que aporta la ganadera, el porcentaje de propiedad de la tierra de la explotacin y la edad del ganadero. La tipologa de los ganaderos de ANI result ser ms compleja que en el pasado. Los resultados indicaron que los tipos de ganaderos variaban en muchos aspectos socioeconmicos y en los perfiles de sus Integration of socioeconomic and genetic aspects involved in the conservation of animal genetic resources 9 ganaderas. Los tipos de ganaderos determinados toman diferentes decisiones en relacin a la modificacin del tamao de su ganadera y a sus objetivos de seleccin. Por otro lado, reaccionaron de forma diferente ante un hipottico escenario de reduccin de las compensaciones econmicas que les planteamos. En este estudio hemos visto que el capital cultural y el econmico interactan y hemos explicado como lo hacen en los distintos tipos de ganaderos. Por ejemplo, los ganaderos que posean un mayor capital econmico, capital cultural formal y capital cultural adquirido sobre la raza, eran los ganaderos cuyos animales tenan una mayor demanda por parte de otros ganaderos, lo cual podra responder a su mayor prestigio social dentro de la raza. Uno de los elementos claves para el futuro de la raza es si este prestigio responde a una superioridad gentica de las animales. Esto ocurrira si los ganaderos utilizaran las herramientas que tienen a su disposicin a la hora de seleccionar animales. Los tipos de ganaderos identificados mostraron tambin claras diferencias en sus formas de colaboracin y en su reaccin a una hipottica variacin de las compensaciones econmicas. Aunque algunos tipos de ganaderos mostraron un bajo nivel de dependencia a estas compensaciones, la mayora se manifestaron altamente dependientes. Por ello cualquier cambio drstico en la poltica de ayudas puede comprometer el desarrollo de las razas autctonas. La adaptacin las polticas de compensaciones econmicas a la heterogeneidad de los ganaderos podra aumentar la eficacia de las mismas por lo que sera interesante explorar posibilidades a este respecto. Concluimos destacando la necesidad de desarrollar polticas que tengan en cuenta la heterogeneidad de los ganaderos. Finalmente abordamos el estudio de la estructura gentica de poblaciones ganaderas. Las decisiones de los ganaderos en relacin a la seleccin de sementales y su nmero de descendientes configuran la estructura demogrfica y gentica de las razas. En la actualidad existe un inters renovado por estudiar las estructuras poblacionales debido a la influencia potencial de su estratificacin sobre la prediccin de valores genmicos y/o los anlisis de asociacin a genoma completo. Utilizamos dos mtodos distintos, un algoritmo de clsteres basados en teora de grafos (GCA) y un algoritmo de clustering bayesiano (STRUCTURE) para estudiar la estructura gentica de la raza ANI. Prestamos especial atencin al efecto de la presencia de parientes cercanos en la poblacin y de la diferenciacin gentica entre subpoblaciones sobre el anlisis de la estructura de la poblacin. En primer lugar evaluamos el comportamiento de los dos algoritmos en poblaciones simuladas para posteriormente analizar los genotipos para 17 microsatlites de 13343 animales de 57 ganaderas distintas de raza ANI. La ANI es un ejemplo de raza con relaciones complejas. Por otro lado, utilizamos el archivo de pedigr de la raza para estudiar el flujo de genes, calculando, entre otras cosas, la contribucin de cada ganadera a la constitucin gentica de la raza. En el caso de las poblaciones simuladas, cuando el FST entre subpoblaciones fue suficientemente alto, ambos algoritmos, GCA y STRUCTURE, identificaron la misma estructura gentica independientemente de que existieran o no relaciones familiares. Por el contrario, cuando el grado de diferenciacin entre poblaciones fue bajo, el STRUCTURE identific la estructura familiar mientras que GCA no permiti obtener ningn resultado concluyente. El GCA result ser un algoritmo ms rpido y eficiente para de inferir la estructura gentica en poblaciones con relaciones complejas. Este algoritmo tambin puede ser usado para reducir el nmero de clsteres a testar con el STRUTURE. En cuanto al anlisis de la poblacin de ANI, ambos algoritmos describieron la misma estructura, lo cual sugiere que los resultados son robustos. Se identificaron tres subpoblaciones diferenciadas que pudieran corresponderse con tres linajes distintos. Estos linajes estaran directamente relacionados con las ganaderas que han tenido una mayor contribucin a la constitucin gentica de la raza. Por otro lado, hay un conjunto muy numeroso de individuos con una mezcla de orgenes. La informacin molecular describe una estructura estratificada de la poblacin que se corresponde con la evolucin demogrfica de la raza. Es esencial analizar en mayor profundidad la composicin de este ltimo grupo de animales para determinar cmo afecta a la variabilidad gentica de la poblacin de ANI. SUMMARY Summary Livestock sector is gradually dominated by intensive and specialized systems where the production environment is controlled and the production traits are the main criteria for the selection of species and breeds. In the meantime, the traditional use of domestic animals for draught work, clothes and manure has been replaced by industrial products. As a consequence of both these changes, the intensively selected breeds closely linked with high-input highoutput production systems have displaced many native breeds where the selection has practically ceased or been very mild. People are now more aware of the state of endangerment among the native breeds and the previously ignored values of livestock are gaining recognition. For some decades now, the economic, socio-cultural, environmental and food security function of livestock breeds have been accepted worldwide and their loss has been recognized as a major problem. Therefore, the conservation of farm animal genetic resources (FAnGR) has been recommended. The conservation of FAnGR is controversial due to the complexity of the evaluation of its functions. This evaluation is difficult due to the nature of FAnGR both as private and public good. As some economists have highlighted, livestock animals are private goods, however, they are also public goods by their functions. Therefore, there is a need to increase the knowledge about the value of all livestock functions since to support the decision-making for the sustainable conservation and breeding of livestock. This is not straightforward since the relative importance of livestock functions depends on time, place, species and breed. Since livestock play a variety of roles, their production is driven by interrelated and everchanging economic, technical, environmental, social, cultural and political elements involving an enormous range of stakeholders. Not only FAnGR functions but also the importance of factors affecting the development and conservation of FAnGR can be very different across geographical areas. Furthermore, heterogeneity can be found even within breeds. Local breeds are nowadays raised by highly diverse farmers in equally diverse farms. It is quite reasonable to think that farmer is the major actor in the in situ conservation of livestock breeds. Thus, there is a need to understand the farmers motivations, decision making processes and the impact of their decisions on the genetic structure of breeds. In this PhD thesis we explore different social, economic and genetic aspects involved in the conservation of local cattle breeds, i.e. FAnGR, in Europe seeking to contribute to the scientific understanding of this complex issue. We aim to achieve a comprehensive view of the processes involved in the conservation and development of local cattle breeds and have made special efforts in discussing the implications of the research results in this respect. The final outcome of the thesis is to illustrate how quantitative methods can be exploited in designing and establishing sound strategies and programmes for the conservation and development of local livestock breeds. Firstly we explored the public non-market attributes of the total economic value (TEV) of livestock, using the Spanish Alistana-Sanabresa (AS) cattle breed as a case study. Total economic value of any good comprises both use and non-use components, where the latter include option, bequest and existence values. For livestock, the direct use values are mainly stemming from production outputs. Indirect use values relate to the role of livestock as a maintainer of rural culture and landscape. The option value is related to the potential use of livestock, the bequest values relate to the value associated with the inheritance of the resources to future generation and the existence values relate to the utility perceived by people from knowing that specific resources exist. We aimed to determine the relative importance of the non-market components of the TEV of the AS breed, the socio-economic variables that influence how people value the different components of TEV and to assess the implications of the Spanish national conservation strategy for the AS breed. To do so, we used a choice experiment (CE) approach and applied the technique to assess peoples willingness to pay (WTP) for the conservation of AS breed. The use of CE allows the valuation of the individual components of TEV for a given good. We analysed the choice data using a random parameter logit (RPL) model. AS breed was found to have a significant public good value. Its most important values were related to the indirect use value due to the maintenance of Zamorian culture and the existence value (both represent over 80% of its TEV). There were several socioeconomic variables influencing peoples valuation of the public service of the breed. In the case of AS breed, the place of living (city or rural area), having seen animals of the breed, having eaten breed products and the respondents attitude towards economic development environment conflicts do influence peoples WTP for AS conservation. We also found that people do not have a complete picture of all the functions and roles that AS breed as AnGR. Therefore, the actions for increasing awareness of AS should go to that direction. The farmers will need incentives to exploit some of the public goods values and maintain the breed population size at socially desirable levels. One such mechanism could be related to the development of agritourism, which would enhance the private good value and provide an important addition to the conservation and utilisation strategy. However, the farmers need a serious evaluation on how to invest in niche product development or how to improve product quality and brand recognition. Using the understanding on the importance of the public function of local cattle we tried to depict the current diversity regarding technical, economic and social factors found in local cattle farming across Europe. To do so we focused in an international collaborative project on the case of fifteen local cattle breeds in eight European countries. We investigated the variation among the countries to detect the common key elements, which affect the viability of local breeds. We surveyed with interviews a total of 355 farms across the fifteen breeds. We used the planned herd size changes by the farmer as an indicator of breed viability. The questionnaire included several economic, technical and social aspects with potential influence on breeds demographic trends. We analysed the data using multivariate statistical techniques, such as discriminat analysis and logistic regression. The factors affecting a local breeds viability were highly heterogeneous across Europe. In some countries, farmers did not recognise any high social value attached to keeping a local cattle breed. Hence there is a need to develop communication programmes across EU countries making people aware about the diversity and importance of values associated to raising local breeds. The countries were also very variable regarding the importance of local markets and the percentage of farm land owned by the farmers. Despite the country specificities, there were also common factors affecting the breed viability across Europe. The factors were from different grounds, from social, such as the age of the farmer and the social appreciation of their work, to technicalorganizational, such as the farmers attitude to collaborating with each other. The heterogeneity found reflects the variation in breeding systems and production environment (in the socioeconomic, technical and ecological sense) present in Europe. Therefore, caution should be taken in implementing common policies at the country level. Variability could also be rather high within countries due to breed specificities. Therefore, the national policies should be flexible to adapt to the specificities. The variables significantly associated with breed viability should be positively incorporated in the conservation strategies, and considered in developing common and/or national policies. The strategy preparation and policy planning should go beyond the provision of a general economic support to compensate farmers for the lower profitability of local breeds. Of particular interest is the observation that the opportunity for farmer collaboration and the appreciation by the society of the cultural, environmental and social role of local cattle farming were positively associated with the breed survival. In addition, farmer's high age is not only a problem of poor generation transfer but it is also a problem because it might lead to a lower attitude to investing in farming activities and to a lower ability to adapt to environment changes. The farmers adaptation capability may be a key point for the viability of local breeds. Decision making tools can help to get a comprehensive view on the conservation and development of local breeds. It allows us to use a systematic and structured approach for identifying and prioritizing conservation and development strategies. We used SWOT (Strengths, Weaknesses Opportunities and Threats) analysis for this purpose and recognized that many conservation and development projects rely on farmers. We developed a quantified SWOT method and applied it in the aforementioned collaborative research to a set of thirteen cattle breeds in six European countries. The method has four steps: definition of the system, identification and grouping of the driving factors, quantification of the importance of driving factors and identification and prioritization of the strategies. The factors were determined following a multi-stakeholder approach and grouped with a three level structure. FAnGR expert groups ranked the factors and a quantification process was implemented to identify and prioritize strategies. The structure of the SWOT analysis allowed analyzing the conservation problem from general down to specific perspectives. Joining breed specific analyses into a common SWOT analysis permitted comparison of breed cases across countries. We identified 99 driving factors across breeds. The across breed analysis revealed that irrelevant factors were consistent. There was high heterogeneity among the most relevant factors and strategies. The strategies increased eligibility as they lost specificity. Although the situation was very heterogeneous, the most promising factors and strategies were linked to the positive aspects (Strengths and Opportunities). Therefore, the future of the studied local breed is promising. The results of our analysis also confirmed the high relevance of the cultural value of the breeds. The most important internal factors (strengths and weaknesses) were related farmers and production systems. The most important opportunities were found in developing and marketing new products, while the most relevant threats were found in selling the current conventional products. In this regard, it should be fruitful to work on farmers motivation, collaboration, and capacity building. We conclude that European policies should focus on general aspects and be flexible enough to be adapted to the country and breed specificities. As mentioned, farmers have a key role in the conservation and development of a local cattle breed. Therefore, it is very relevant to understand the implications of farmer heterogeneity within a breed for its viability. In the fourth part of the thesis, we developed a general farmer typology to help analyzing the relations between farmer features and farm profiles, herd dynamics and farmers decision making. In the analysis we applied and used the sociological framework of economic and cultural capital and studied how the determined farmer types were linked to farm profiles and breeding decisions, among others. The typology was based on measurable socioeconomic factors indicating the economic and cultural capital of farmers. A group of 85 farmers raising the Spanish Avilea-Negra Ibrica (ANI) local cattle breed was used to illustrate and test the procedure. The farmer types were defined by a hierarchical cluster analysis with a set of canonical variables derived from the following five the socioeconomic factors: the formal educational level of the farmer, the year the farmer started keeping the ANI breed, the percentage of the total family income covered by the farm, the percentage of the total farm land owned by the farmer and the farmers age. The present ANI farmer types were much more complex than what they were in the past. We found that the farmer types differed in many socioeconomic aspects and in the farms profile. Furthermore, the types also differentiate farmers with respect to decisions about changing the farm size, breeding aims and stated reactions towards hypothetical subsidy variation. We have verified that economic and cultural capitals are not independent and further showed how they are interacting in the different farmer types. The farmers related to the types with high economic, institutionalized and embodied cultural capitals had a higher demand of breeding animals from others farmers of the breed, which may be related to the higher social prestige within the breed. One of the key implications of this finding for the future of the breed is whether or not the prestige of farmers is related to genetic superiority of their animals, what is to say, that it is related with a sound use of tools that farmers have available to make selection decisions. The farmer types differed in the form of collaboration and in the reactions to the hypothetical variation in subsidies. There were farmers with low dependency on subsidies, while most of them are highly dependent on subsidies. Therefore, any drastic change in the subsidy programme might have influence on the development of local breeds. The adaptation of these programme to the farmers heterogeneity might increase its efficacy, thus it would be interesting to explore ways of doing it. We conclude highlighting the need to have a variety of policies, which take into account the heterogeneity among the farmers. To finish we dealt with the genetic structure of livestock populations. Farmers decisions on the breeding animals and their progeny numbers shape the demographic and genetic structure of the breeds. Nowadays there is a renovated interest in studying the population structure since it can bias the prediction of genomic breeding values and genome wide association studies. We determined the genetic structure of ANI breed using two different methods, a graphical clustering algorithm (GCA) and a Bayesian clustering algorithm (STRUCTURE) were used. We paid particular attention to the influence that the presence of closely related individuals and the genetic differentiation of subpopulations may have on the inferences about the population structure. We first evaluated the performance of the algorithms in simulated populations. Then we inferred the genetic structure of the Spanish cattle breed ANI analysing a data set of 13343 animals (genotyped for 17 microsatellites) from 57 herds. ANI breed is an example of a population with complex relationships. We used the herdbook to study the gene flow, estimation among other things, the contribution of different herds to the genetic composition of the ANI breed. For the simulated scenarios, when FST among subpopulations was sufficiently high, both algorithms consistently inferred the correct structure regardless of the presence of related individuals. However, when the genetic differentiation among subpopulations was low, STRUCTURE identified the family based structure while GCA did not provide any consistent picture. The GCA was a fast and efficient method to infer genetic structure to determine the hidden core structure of a population with complex history and relationships. GCA could also be used to narrow down the number of clusters to be tested by STRUCTURE. Both, STRUCTURE and GCA describe a similar structure for the ANI breed suggesting that the results are robust. ANI population was found to have three genetically differentiated clusters that could correspond to three genetic lineages. These are directly related to the herds with a major contribution to the breed. In addition, ANI breed has also a large pool made of individuals with an admixture of origins. The genetic structure of ANI, assessed by molecular information, shows a stratification that corresponds to the demographic evolution of the breed. It will be of great importance to learn more about the composition of the pool and study how it is related to the existing genetic variability of the breed.

Esta tesis estudia y analiza el que fue importante convento de los agustinos calzados, extramuros de la villa de Madrigal de la Altas Torres. El conjunto que en su da fue llamado el Escorial de Castilla, donde muri fray Luis de Len en 1591, con ctedras de teologa y filosofa y casa de captulos provinciales, ha visto languidecer sus fbricas en paralelo al declive de Castilla y al de la propia villa de Madrigal, hasta que (al igual que en otros muchos casos) los decretos de supresin y desamortizacin en el siglo XIX, cerraron definitivamente sus puertas como convento y las abrieron a la destruccin y a la ruina que hoy presenta. En mi condicin de arquitecto e historiador he pretendido seguir una metodologa que ane tanto los aspectos histricos del edificio, que permitan un mayor conocimiento del mismo, como otros aspectos estrictamente arquitectnicos en su doble vertiente compositiva y constructiva-tipolgica, dentro del marco de la arquitectura clasicista en la que de forma clara se define el convento. Estos campos se completan con los levantamientos planimtricos del edificio y con su modelizacin, que tratan de analizar la evolucin del convento a travs de su tiempo, reinterpretando el volumen que pudo tener en el siglo XVI y XVII (el imaginado por el tracista). Se trata pues de una metodologa que quiere ser integradora de disciplinas que frecuentemente discurren por vas separadas, pero que tienen el objetivo comn sealado. En el primer tomo, el estudio histrico del convento recoge los aspectos cronolgicos del edificio, localizados en una sistemtica y razonable bsqueda en los archivos y fuentes documentales, as como las relaciones de poder y de patronazgo que a distintas escalas se establecen entre el convento y la Corte (especialmente durante los siglos XV y XVI), y otro tipo de conexiones e influencias (menores pero no por ello menos importantes) entre los frailes de Madrigal y la orden agustina calzada a la que pertenecen, o entre el convento y su territorio, identificado principalmente con la villa de Madrigal. Es en definitiva el conocimiento de quines, (frailes, arquitectos, maestros, artistas etc. ), cmo y cundo han intervenido en la ideacin, ejecucin, sostenimiento (e incluso destruccin) del edificio, dentro de los avatares sociopolticos y administrativos de cada periodo. No podemos olvidar por otra parte, los aspectos econmicos, que como veremos juegan un papel fundamental en la propia edificacin del convento, cuyas fases constructivas se corresponden con aportaciones econmicas extraordinarias, emanadas principalmente de la enorme fortuna personal de D. Gaspar de Quiroga, arzobispo de Toledo e Inquisidor General con Felipe II. El anlisis del edificio se centra principalmente en su fase como convento de Agustinos, a partir de 1528, cuando las monjas agustinas que lo fundaron y habitaron se trasladan al antiguo palacio de Juan II, que reciben de Carlos I, y se lo ceden a los frailes por mediacin de Santo Toms de Villanueva, y su final tras las desamortizaciones decimonnicas. El segundo tomo recoge la descripcin del edificio y su evolucin en el tiempo, con las limitaciones que supone la prdida actual de la mayor parte de sus muros. Se exponen tambin en este captulo algunos de los aspectos constructivos del edificio, sus medidas y proporciones, que de alguna manera nos introducen en el captulo de la arquitectura clasicista. Se estudia la arquitectura del convento en esta etapa, que abarca un periodo comprendido entre 1585 y 1645, por ser el momento en que se construye la prctica totalidad del mismo mediante los recursos y el patronazgo del arzobispo toledano. Tanto la traza del convento como la de la iglesia pertenecen al momento de mayor nfasis y dinamismo del clasicismo vallisoletano, representado por la figura de Juan del Ribero Rada, que interviene en ambos proyectos, siendo de especial inters el descubrimiento de que ste arquitecto es tambin el autor de la traza conventual, tal como se pone de manifiesto en el concurso de fray Luis de Len de 1590, amplindose el conocimiento de su obra arquitectnica. En relacin con este anlisis de la arquitectura clasicista de Juan de Ribero en Madrigal, se ha realizado un levantamiento planimtrico exhaustivo, que por s mismo compone una parte substancial de esta tesis. Este levantamiento nos ha permitido dar un paso ms, procediendo a la reconstruccin idealizada de sus volmenes, tal como pudo ser concebida por el tracista y por el propio Quiroga, basndonos en los datos sobre el edificio que nos aportan tanto sus restos, como las diversas fuentes documentales. Ante un edificio excepcional y actualmente destruido casi en su totalidad 1, se debe entender este trabajo como parte de un proceso de recuperacin de nuestra memoria histrica colectiva, entendiendo que el conocimiento de un edificio va ms all de la mera acumulacin de datos.

No romance O Idiota, Dostoivski cria, por meio do prncipe Mchkin, uma personagem com as caractersticas do Cristo. Sabe-se que a Bblia, principalmente o Novo Testamento, acompanhou o escritor desde sua infncia at o momento de sua morte. O primeiro captulo, dedicado ao referencial terico da pesquisa, lida com o universo da linguagem. Tanto o texto literrio quanto a literatura bblica procedem do mito. Neste sen-tido, religio e literatura se tocam e se aproximam. O segundo captulo foi escrito na inteno de mostrar como o Cristo e os Evangelhos so temas, motivos e imagens recorrentes na obra de Dostoivski. A literatura bblica est presente, com mais ou menos intensidade, em diversas das principais obras do escritor russo e no somente em O Idiota. A hiptese de que Dostoivski cria um Cristo e um Evangelho por meio de O Idiota demonstrada na anlise do romance, no terceiro captulo. A tese proposta : Dostoivski desenvolve um evangelho literrio, por meio de Mchkin, misto de um Cristo russo, ao mesmo tempo divino e humano, mas tambm idiota e quixotesco. Na dinmica intertextual entre os Evangelhos bblicos e O Idiota, entre Cristo e Mchkin, a literatura e o sagrado se revelam, como uma presena divina. Nas cenas e na estruturao do enredo que compe o romance, Cristo se manifesta nas aes de Mchkin, na luz, na beleza, mas tambm na tragicidade de uma trajetria deslocada e antinmica. O amor e a compaixo ganham forma e vida na presen-a do prncipe, vazio de si, servo de todos.

A questo que nos propusemos analisar consiste em perceber como que a cultura pode ser um fator de desenvolvimento e em que moldes se tem processado. Em primeiro lugar, procuraremos definir o conceito de cultura, tendo em conta as diferentes acees que tem adquirido ao longo do tempo, para estabelecer o que que hoje quer dizer cultura. No fundo, abordar de que maneira a rea da cultura se interliga com outros domnios, tais como os direitos humanos, a educao, a economia, o ambiente. Tambm procurar debater de que modo estas reas so fundamentais para a compreenso da noo atual de cultura e como interferem na questo do desenvolvimento. Alm disso, abordaremos o papel fundamental das indstrias culturais e criativas para a compreenso do que aqui est em causa. Deste modo, daremos resposta a questes como a forma de a cultura poder ser um fator de criação de emprego, qualificao e formao e como pode ser um impulso economia. Ao considerar que a cultura tem um carter pragmtico, lanaremos um olhar sobre a realidade de So Tom e Prncipe, de que analisaremos os principais espaos de criatividade, as principais questes que se conjugam com o fator cultural bem como o papel que lhe atribudo enquanto um elemento a ter em conta nas polticas pblicas. Em suma, pretendemos perceber o que ainda preciso ser feito, procurando aliar um dos pontos que constituem a chave da cultura em STP a tradio s exigncias das novas abordagens no setor cultural.

From the context of the degrees creation of Spanish literature and languages course, at UFRN, came the motivation to make this research, that presents a literary study of a poets group known as Generacin del 27, that came in to light at Spain, on 1920. A lot of aspects of this study are themes of many others disciplines, of this degree (Spanish Literature II, IberianAmerican Literature, Spanish Culture, Translation in Spanish Language). This work will also serve as inspiration to new reflections and proposes of translations, as bridges between the language that goes and the other that comes. It is the Translation as comprehensions negotiation between languages, it is the decir casi lo mismo, here in poems form (ECO, 2007), in the attempt to conclude new learning, that will be shared with undergraduate and graduate students, being at teaching area, extension or new researches. To contextualize this generations studies, were elected the anthologies organized by Gerardo Diego, called Poesa Espaola (Antologas), published on 2007, by Ediciones Ctedras, and the Antologa Comentada de La Generacin del 27, wrote by Vctor Garca de La Concha, published on 2006, by Editorial Espasa Calpe. The research took Generacion Del 27 as their object of research and - from many others critical reading about the poetry made by those young poets, their creative vocation of aesthetics and vanguard wanted to understand the context of literarys creation of those poets del 27. We form our foundation with contributions by Antonio Maravall (2009), Eugenio Dors (s.d) Severo Sarduy (1999), Lezama Lima (2011), Alfonso Reyes (1958) e Deleuze (2005) among others that brought the comprehension of the baroques language, giving emphasis to pluridirectional movement, deconstructing its linearity, creating others new forms, as returns, circles, spirals favoring encounters, detachment or equal points of departure and arrivals. In this way, the poets del 27 approached the baroque of six hundred on a re-reading, and made of the third centenarys celebration of the Gngoras a Mirada exuberante death, to the return of baroques spirit. Alfonso Reyes e Rubn Daro said that real lights highlighted the paths of this poets generation: The light that desdobra scintillates on Garca Lorca, Jorge Gulln, Dmaso Alonso, Gerardo Diego and the bullfighter Ignacio Snchez Mejas, poets that expressed tributes in big style to Soledades author, at Madrids Caffe and all Spain.

The farms rural dwellings of creation from the Serid Potiguar microregion, built in the nineteenth century, became a reference by its vernacular character, i.e. these buildings, besides having recognized relevance to the identity of the region, they are adapted to the conditions of the place in many aspects (economic, cultural, construction, physical, et.) and consist in protective spaces in relation to hostile characteristics of Serids climate. Considering the above premise, the following question arises: What characteristics of the nineteenth century Serid Potiguars cattle farms are crucial for them to be a protective space in relation to the semiarid climate? In order to answer the question, this research aim to identify which particularities of the Serids farmhouses that contribute to adaptability in these buildings to semiarid climate, as protection environments; and contribute to the stock valuation of the architectural heritage concerned. Therefore, procedures were adopted divided into two stages. Were first identified the recurring characteristics in the studied buildings, through typological study performed from existing inventories (DINIZ, 2008; FEIJ, 2002; IPHAN, 2012). To define the type it worked up with the concept that merges Durands analytical typology that identifies the similarities and differences to classify buildings, having the character of historical survey and architectural documentation, with the definition proposed by Argan (1963) that the type is not defined a priory, but the deduction from a number of illustrative cases which have formal and functional similarity with each other. Then worked up in a sample of five different types with each other, defined by the possibility of access to the interior of the houses, proximity to other copies, good state of conservation and preservation. The contemplated farms were: Pitombeiras, Agenus e Garrotes in Acaris town, and the municipality of Caic, Palma and Penedo. The second stage consists of the architectural survey, photographic record, digital three-dimensional modeling (aiming to expand the existing documentation and registration) and thermal monitoring over approximately a representative day in five farmhouses, relating the thermal performance of the houses with their individual characteristics. The selected variables for analysis monitoring are based on the thermal comfort adaptive model (SPAGNOLO and DE DEAR, 2003 apud NEGREIROS, 2010). The characteristics of the houses were analyzed as meeting the passive thermal conditioning strategies recommended by NBR 15220 (ABNT, 2005), for the bioclimatic zone 7 where the municipalities of Caic and Acari are located. The houses analysis of the operating temperatures revealed that 90% of the times of day the environments are within the comfort range. The farmhouses, which had a higher degree of compliance with recommended bioclimatic strategies, had the best thermal performance. In environments (usually the kitchen and rooms with low ceiling heights, exposed to west radiation) which still had discomfort hours, the thermal comfort can be reached with air movement approximately 1,0 m/s.

Citizens say they are very concerned about the environment, and they know the role they play in their deterioration; but there is a gap between this proclaimed interest and the mobilization against environmental problems. Several news published between 2010 and 2011 about the Spanish energy policy and Doana have economic and social aspects, that sometimes are confused with environmental aspects. It is worthy of study, therefore, to analyze how the press reflects that citizen interest; and how a critical issue as the quality of the information can influence the attitude of citizens in issues related to the environment. If the journalistic practice does not meet quality its function, it will condition the social participation.

This text deals with transnational strategies of social mobility in Ecuadorian migrant households in Spain. We apply the capital accumulation model (Moser, 2009) for this purpose. The main target of this article is, beyond thinking in terms of capital stock and accumulation, the analysis in depth of the dynamics of the different types of capital, that is to say, how they interact with each other in the framework of the social mobility strategies of the migrants and their families. We are bringing into light the way some households adopt investing decisions in capitals that don't translate into any addition or earnings in all cases, on the contrary, concentrating all their efforts on the accumulation of a certain asset they may, in some cases, lead to a loss of another. We will concentrate our analysis primarily on the dynamics between the physical and financial capital and the social and emotional capital, showing the tensions produced between these two types of assets. At the same time, we will highlight how migrants negotiate their family strategies of social mobility in the transnational area. Our study is based in empirical material obtained from qualitative fieldwork (in-depth interviews) with families of migrants in the urban district of Turubamba Bajo -(south of Quito) and in Madrid. A series of households were selected where interviews were carried out in the country of origin as well as in the context of immigration, with different family members, analysing the transnational social and economic strategies of families of migrant members. Family members of migrants established in Spain were interviewed in Quito, as well as key informants in the district (school teachers, nursery members of the staff, etc.). The research was framed within the projects "Impact of migration on the development: gender and transnationalism", Ministry of Science and Innovation (SEJ2007/63179) (Laura Oso, dir. 2007-2010),"Gender, transnationalism and intergenerational strategies of social mobility", Ministry of Economy and Competitiveness (FEM2011/26210) (Laura Oso, dir. 201-1-2015) and Gender, Crossed Mobilities and Transnational Dynamics, Ministry of Economy and Competitiveness (FEM2015-67164).

Este ensayo pretende esbozar el rol y el impacto que ejerce la publicidad por televisin en una economa dependiente como la nuestra, presentndose el marco terico necesario para centrar el problema en la perspectiva correcta. En los tres primeros captulos se tratarn los aspectos microscpicos, centrando el anlisis en los sujetos de la actividad econmica y su ubicacin frente a la publicidad: el consumidor y el capitalista, y el intermediario entre ellos: el publicista. Tal exposicin se basa en la evaluacin relativamente minuciosa de cerca de doscientos anuncios grabados a lo largo del segundo semestre del ao pasado, tal como fueron transmitidos por los canales de televisin de mayor sintona en Lima Metropolitana. Estimamos que con ello cubrimos alrededor del 90% del universo, muestra que consideramos nos llevar a conclusiones que pueden generalizarse sin temor. Y, arriesgando un poco ms, pensamos incluso que lo que puede aprenderse de los anuncios comerciales de la televisin y tal como atacaremos el problema, es susceptible de proyectarse a los anuncios de radio, peridicos, etc. y a la publicidad de exteriores.

Co-management, or participative management of fisheries, consists of returning or opening to the community the management of fisheries. This work, carried out in northern Mozambique, analyzed the ecological and social impacts of the implementation of co-management of fisheries. Firstly 198 species of fish were found and photographed and a guide to identification of species - essential to who works in the marine environment was produced. Following, the spill-over effect was identified in a marine sanctuary. It occurred after 6 years and only for herbivore fishes and not to the carnivores. In order to evaluate comanagement of fisheries effects, the captures of the entire province were analyzed. No differences were found in the diversity of the species caught, but an increase of the fish size was detected: this size was smaller in the fishing centers with no CCP (Community Fishing Councils), slightly bigger in the fishing centers with CCP and even bigger in the fishing centers with a more efficient management. At the same time it was observed that the size of the fish caught is bigger in the fishing centers further away from the markets. In addition to the ecological effects and the effects on fisheries, it was also analyzed the point of view of those who live the co-management. The socioeconomic factors that have a stronger influence in their perceptions are the age and the wealth. Finally and according to the CCP members, their main achievements are in the fisheries inspection and in the creation of conservation areas. Their main difficulties are the lack of means of transportation and the lack of recognition of the CCP's authority; both among the population and in the coordination with local authorities. This thesis pioneered in Mozambique in assessing the effects of Community sanctuaries and the effects of CCP on fisheries as well as by revealing the profile of the supporters of co-management and marine sanctuaries. Finally, an assessment of the matter of fact problems that the communities have to face when implementing co-management was also made.
