Biofouling of crypts of historical and architectural interest at la Plata Cemetery (Argentina)

Cemeteries are part of the cultural heritage of urban communities, containing funerary crypts and monuments of historical and architectural interest. Efforts aimed at the conservation of these structures must target not only the abiotic stresses that cause their destruction, such as light and humidity, but also biofouling by biotic agents. The purpose of this study was to assess the development of biofouling of several historically and architecturally valuable crypts at La Plata Cemetery (Argentina). Samples obtained from the biofilms, lichens, and fungal colonies that had developed on the marble surfaces and cement mortar of these crypts were analyzed by conventional microbiological techniques and by scanning electron microscopy. The lichens were identified as Caloplaca austrocitrina, Lecanora albescens, Xanthoparmelia farinosa and Xanthoria candelaria, the fungi as Aspergillus sp., Penicillium sp., Fusarium sp., Candida sp. and Rhodotorula sp., and the bacteria as Bacillus sp. and Pseudomonas sp. The mechanisms by which these microorganisms cause the aesthetic and biochemical deterioration of the crypts are discussed.

Teaching in Landscape

“We, the landscape architects, concerned with the future development of our landscapes in a fast changing world, believe that everything, influencing the way in which the outdoor environment is created, used, and maintained is fundamental to sustainable development and human well-being. We, being responsible for the improvement of the education of future landscape architects to enable them to work for a sustainable environment within the context of our natural and cultural heritage”. (IFLA/UNESCO 2005) CHARTER FOR LANDSCAPE ARCHITECTURAL EDUCATION) Nowadays, respect and appreciation of the landscape sustainably grow. Landscape Architecture professionals are makers encourage and guide this growth. However, there is still no legal recognition of the landscape profession in Spain. For this reason we present this paper that shows the current framework in which appear a professional educated with masters and specialized courses, but it lacks a defined work area and unique in its business learned. We present the demands of both IFLA and the EFLA and teaching lines proposed by these organizations at European level are distinguished. Furthermore, we analyze the national scene and major training centres are distinguished.

Representación 3D de petroglifos: propuesta de metodología de modelización de los grabados del Valle de Tamanart, Marruecos.

La modelización tridimensional se ha ido implementando como una de las mejores formas de documentación del patrimonio histórico. En concreto, en lo que se refiere a la documentación de petroglifos resulta especialmente interesante en su estudio y difusión. Actualmente, existen diversos métodos de obtener estos modelos 3D, que implican diferentes tipos de instrumental, como escáneres láser o cámaras fotográficas, material informático y software. En este Trabajo Fin de Máster se pretende obtener una visión general de estos métodos,así como proponer una metodología basada en la fotogrametría de objeto cercano, para las necesidades de un proyecto concreto: el proyecto Tamanart en Marruecos. Para ello se realizan dos pruebas; una de laboratorio y otra en el Museo Arqueológico Nacional, para comprobar la viabilidad de esta metodología y sus futuras aplicaciones. ABSTRACT: 3D modeling has been implemented in the last years as one of the best ways to document historical and cultural heritage. In particular, referring to petroglyph documentation it is specially interesting to its study and dissemination. Nowadays, there are several methods to obtain this 3D models that implies different kinds of instruments, like laser-scanners or photographic cameras and computer hardware and software. In the present Master’s Dissertation it is intended to obtain a general vision of this methods,as well as propose a methodology using closed range photogrammetry, based in the needs of a specific project: Tamanart Project, in Morocco. For this purpose two tests are made, one of them in laboratory and the other in the Museo Arqueológico Nacional, to check the feasibility of this methodology and their future applications.

Bóvedas de crucería rebajadas hispanas: geometría, estructura y construcción

La arquitectura histórica constituye un ámbito de notable singularidad dentro del patrimonio cultural, ya que representa uno de los máximos exponentes de la cultura material de las sociedades precedentes. Su adecuada conservación y preservación debe ir necesariamente precedida de un riguroso y profundo conocimiento de sus valores culturales, de ahí la importancia de las investigaciones en este campo. Entre todos los elementos que configuran las edificaciones históricas, son probablemente las bóvedas los elementos más singulares, dada su relevancia desde un punto de vista tanto estético como estructural y constructivo. Hasta la fecha, los estudios centrados en los abovedamientos medievales góticos han aportado visiones generales del conjunto de obras, estableciendo las pertinentes clasificaciones y poniendo de manifiesto la notable variedad de tipos de bóvedas de crucería. La presente investigación tiene su origen en la necesidad de profundizar en el conocimiento de este sistema constructivo mediante el estudio específico y sistemático de un tipo concreto de abovedamiento: las bóvedas de crucería rebajadas que sustentan los coros altos de los templos. En concreto, el análisis se ha centrado en aquellos abovedamientos construidos en la Corona de Castilla durante los reinados de los Reyes Católicos y Carlos I, puesto que es en este momento de transición entre el mundo medieval y la Edad Moderna con una coexistencia de la tradición medieval y las nuevas ideas renacentistas cuando se crean las más singulares obras. Por lo tanto, el trabajo desarrollado se ha centrado en el estudio e interpretación de los procesos de diseño, trazado y construcción específicos de cada una de las bóvedas. Más allá de un enfoque descriptivo o basado en una visión actual, se ha tratado de profundizar en los métodos, sistemas y recursos que los maestros canteros emplearon, lo que ha obligado a adoptar en la medida de lo posible la mentalidad y conocimiento bajomedievales. Con estas premisas se ha desarrollado una investigación que necesariamente se ha apoyado en la contextualización histórica de cada una de las bóvedas, generándose un catálogo completo de las obras. Posteriormente, se ha desarrollado una toma de datos y un análisis individualizado de cada una de ellas, para poder obtener una interpretación de su proceso de diseño y construcción. Finalmente, se ha abordado un estudio comparativo del conjunto de las obras, poniendo en relación sus características históricas, geométricas, constructivas y estructurales. Ello ha permitido obtener unos resultados novedosos respecto a las principales cuestiones sobre el diseño y construcción de las bóvedas de crucería rebajadas, poniendo de relieve su singularidad y el profundo conocimiento de los maestros canteros que las crearon. De este modo, se ha pretendido avanzar en la investigación y sentar las bases para posteriores trabajos en el ámbito de los abovedamientos de crucería. Historical architecture is a quite singular field when considering cultural heritage, because it is one of the most important exponents of the material culture previous societies. Its proper conservation and restoration must be preceded of a rigorous and deep knowledge of the cultural values, and that is why researches in this fi eld are very important. The study of historical architecture has been developed traditionally from the viewpoint of History of Art and Architecture. Thanks to such discipline, it has been possible to establish and systematize several architectonical types and styles. However, there has been a lack in relationship with the analyses focused on the structural and constructive historical systems, which has been recently compensated by the gradual development of the discipline of Construction History. Among the several elements which form the historical buildings, the vaults are probably the most singular elements, thanks to their aesthetic, constructive and structural relevance. To date, the studies focused on the medieval gothic vaults have provided general visions of the whole group of works, which has allowed defi ning the proper classifi cations and underlining the great variety of kinds of ribbed vaults. The present research has its origin in the need of a deeper knowledge of this specific constructive system. For that reason, a specifi c and systematic analysis of a particular kind of vaults has been developed. It is focused on the surbased ribbed vaults which support the elevated choirs of some churches. In particular, it includes the works built in the Crown of Castille during the kingdoms of Catholic Kings and Carlos I, because at this precise moment of transition from the medieval world into de Modern Age with a coexistence of the medieval tradition and the new classicistic ideas the most singular and relevant surbased vaults were built. In this way, the analysis has been focused in the study and interpretation of the design, tracing and construction methods of each vault. More than a descriptive approach or an analysis based on our contemporary point of view and knowledge, this research has studied the methods, systems and resources of master masons in depth. Then, it has been necessary to adopt as much as possible their mentality, as well as the late medieval knowledge. With the above mentioned premises, the research has been developed including the historical contextualization of each vault, providing also a complete catalogue of such works. After obtaining the proper survey, measurements and other complementary data, each one has been analyzed in order to develop a hypothesis of the design and construction process. Finally, a comparative study has been carried out, which has allowed putting in relationship the historical, geometrical, constructive and structural features of the whole group of vaults. This research has provided novel results about de design and construction of surbased ribbed vaults, underlining their singularity as well as the deep knowledge of master masons who created them. In this way, we have tried to go further in this scientific field and to set the basis for latter researches focused on ribbed vaults.

Restauración virtual del patrimonio sonoro. Aplicación al antiguo rito hispánico

Una de las aplicaciones más interesantes de las tecnologías de Realidad Acústica Virtual es la posibilidad de recuperar el patrimonio cultural del sonido de los recintos históricos que se han perdido o cuyas características se han modificado a lo largo de los siglos. En este trabajo, las tecnologías de realidad acústica virtual se utilizan para tratar de reconstruir virtualmente el sonido producido en las actividades litúrgicas del antiguo rito hispánico. Bajo este nombre se conoce a la liturgia que celebraban los cristianos de la península ibérica hasta su prohibición, en favor del culto romano, a mediados del siglo XI. El rito hispánico -también conocido como rito visigótico-mozárabe- es una de las manifestaciones culturales más interesantes de la Alta Edad Media en occidente. Se trata de un patrimonio cultural desaparecido, tanto desde el punto de vista de las señales sonoras que lo integraban -ya que la mayoría de las melodías que conformaban el rito se han perdido- como desde el punto de vista de los espacios en los que se desarrollaba, debido a que las iglesias conservadas de la época han experimentado modificaciones a lo largo de los siglos que alteran sus condiciones acústicas con respecto a las que tenían en el periodo de vigencia de esta liturgia. Para llevar a cabo este proyecto, se han realizado modelos acústicos digitales de un grupo representativo de iglesias prerrománicas de la Península Ibérica en su estado primitivo. Se ha procurado que las iglesias seleccionadas representen la variedad de comportamientos acústicos esperables en este tipo de edificios. Con este objetivo, se han elegido cinco iglesias prerrománicas que presentan diferencias sustanciales en los parámetros que, a priori, van a influir en mayor manera a su comportamiento acústico: el volumen del recinto, la forma de la planta y el tipo de cubierta. El proceso de creación de los modelos acústicos digitales de las iglesias se ha dividido en dos fases: en la primera se han creado modelos de los edificios en su estado actual, que se han validado a partir de los datos obtenidos en mediciones acústicas realizadas in situ; a partir de los modelos validados de las iglesias en su estado actual, en la segunda fase se han generado los modelos acústicos digitales correspondientes al estado primitivo de las mismas, modificando los modelos anteriores de acuerdo con las hipótesis de reconstrucción propuestas en las investigaciones arqueológicas más recientes. Se han realizado grabaciones en cámara anecoica de una serie de piezas del repertorio original del canto mozárabe. Las grabaciones se han llevado a cabo con un array esférico compuesto por 32 micrófonos, con objeto de obtener información sobre la directividad de la emisión sonora de los cantantes, que se aplicará en las auralizaciones. Finalmente, se han realizado diversas auralizaciones, teniendo en cuenta diferentes configuraciones litúrgicas que eran usuales en este rito. ABSTRACT One of the most interesting applications of the Acoustic Virtual Reality technologies is the possibility to recover the cultural heritage of the sound of the historical sites that have been lost or whose characteristics have been modified through time. In this work, Acoustic Virtual Reality technologies are used to try to reconstruct virtually the sound produced in the liturgical activities of the Hispanic Rite. This is the name given to the liturgy celebrated by Christians of the Iberian Peninsula prior to the introduction of the Roman cult in the mid-eleventh century. The Hispanic Rite (also known as Visigothic or Mozarabic rite) is one of the most interesting cultural manifestations of the Middle Ages. It is a lost cultural heritage, both from the point of view of the sound signals that were used since the majority of the melodies that conformed the rite have been lost, and from the point of view of the spaces in which this liturgy was celebrated, because the churches preserved from that era have changed over the centuries altering its acoustic conditions respect to which they were in the period in which this liturgy was in effect. To carry out this project, acoustic models of a representative group of the pre-Romanesque churches in the Iberian Peninsula have been made in his primitive state. To select the sample of buildings to study, efforts have been made to ensure that the selected churches were representative of the range of expected acoustic behaviors in this type of buildings. Five churches have been selected, showing differences in the parameters that have the greatest influence on their acoustic behavior: the enclosure volume, the shape of the floor plan and the type of roof. The process of creating digital acoustic models of the churches has been divided into two phases. In the first phase acoustic models of the churches in its current state have been created. These models have been validated with the data obtained from in situ acoustic measurements. From the validated models of churches in its current state, in the second phase, changes in the acoustic models have been performed in order to represent the primitive state of the churches, according to the historical reconstruction hypothesis that have been proposed in the most recent archaeological investigations. Anechoic recordings of a series of pieces of the original Mozarabic Chant repertoire have been recorded. The recordings were made with a spherical array composed of 32 microphones, in order to obtain information on the directivity of the sound emission of the singers. These directivity data will be used to simulate the directional radiation of the sound sources in the auralizations. Finally, auralizations were produced corresponding to different liturgical configurations which were common in this rite.

Drought estimation maps by means multidate landsat fused images

The purpose of this paper is to analyze the usefulness of traditional indexes, such as NDVI and NDWI along with a recently proposed index (NDDI) using merged data for multiple dates, with the aim of obtaining drought data to facilitate the analysis for government premises. In this study we have used Landsat 7 ETM+ data for the month of June (2001-2009), which merged to get bands with twice the resolution. The three previous indices were calculated from these new bands, getting in turn drought maps that can enhance the effectiveness of decision making.

Land Cover Mapping by an Optimized Object-Oriented Approach. Case of Study Mediterranean Landscapes

Remote sensing information from spaceborne and airborne platforms continues to provide valuable data for different environmental monitoring applications. In this sense, high spatial resolution im-agery is an important source of information for land cover mapping. For the processing of high spa-tial resolution images, the object-based methodology is one of the most commonly used strategies. However, conventional pixel-based methods, which only use spectral information for land cover classification, are inadequate for classifying this type of images. This research presents a method-ology to characterise Mediterranean land covers in high resolution aerial images by means of an object-oriented approach. It uses a self-calibrating multi-band region growing approach optimised by pre-processing the image with a bilateral filtering. The obtained results show promise in terms of both segmentation quality and computational efficiency.

Assessment of Underground Wine Cellars Using Geographic Information Technologies

Geographic information technologies (GIT) are essential to many fields of research, such as the preservation and dissemination of cultural heritage buildings, a category which includes traditional underground wine cellars. This article presents a methodology based on research carried out on this type of rural heritage building. The data were acquired using the following sensors: EDM, total station, close-range photogrammetry and laser scanning, and subsequently processed with a specific software which was verified for each case, in order to obtain a satisfactory graphic representation of these underground wine cellars. Two key aspects of this work are the accuracy of the data processing and the visualization of these traditional constructions. The methodology includes an application for geovisualizing these traditional constructions on mobile devices in order to contribute to raising awareness of this unique heritage.

Paisajes de la sal en Andalucía

Los paisajes protagonistas de esta investigación han sido creados gracias a la actividad de las salinas, explotaciones “donde se beneficia la sal de las aguas del mar o de ciertos manantiales, cuando se ha evaporado el agua.” (RAE). Son lugares de características únicas, tanto por sus valores naturales y medioambientales, como por los valores culturales, patrimoniales, históricos, sociales e identitarios, “resultado de la acción e interacción de factores naturales y humanos en el territorio” (CEP, 2000). Existen salinas en muchos lugares del mundo, pero es en la Península Ibérica donde se encuentra la mayor concentración de estas explotaciones en toda Europa y, por consiguiente, de los singulares paisajes asociados y generados por ellas. Es también la única región europea donde existen salinas de interior que utilizan métodos de evaporación para la obtención de sal: las energías y circunstancias naturales aprovechadas en ellas, sol, viento, gravedad y humedad relativa, propician la evaporación del agua salada, una de las estrategias fundamentales para su funcionamiento. Esta circunstancia determina su posición geográfica en el territorio y su dependencia de los ciclos climáticos estacionales, del régimen hidrológico, la estructura geológica del subsuelo, la geomorfología y la acción humana para potenciar la eficiencia de los procesos productivos, creando para ello un extenso e interesante patrimonio natural y cultural en torno a ellas. Por tanto, son también paisajes culturales, resultado de un proceso artesanal de producción y comercialización de la sal, que se articula a través de la construcción de una serie de instalaciones preindustriales diseminadas y conectadas en puntos estratégicos del territorio costero e interior. La presente tesis aborda la grave situación a la que se enfrentan en la actualidad los paisajes ibéricos de la sal, concretamente los ubicados en la Comunidad Autónoma de Andalucía, que están sufriendo un ávido proceso de abandono y desaparición desde mediados del s. XX, con la consiguiente pérdida para la sociedad de este valioso patrimonio cultural y natural, que se ha ido construyendo durante siglos, prácticamente desde el inicio de la humanidad. De las diversas tipologías de salinas que existen, se han seleccionado las explotaciones, tanto marítimas como de interior, que utilizan o han utilizado en su origen técnicas de explotación artesanal basadas en la evaporación. El interés de esta acotación tipológica se ha basado en las relaciones de dependencia que estas explotaciones de sal establecen con el entorno físico y climático donde se ubican para poder existir y funcionar. El objetivo principal de esta investigación ha perseguido el establecimiento y definición de un marco territorial, global e integrador, para los paisajes culturales salineros andaluces, a través de la observación directa realizada durante el trabajo de campo, el análisis de textos, imágenes, documentos, gráficos, palabras y entrevistas abiertas. Lo anterior ha permitido identificar, clasificar, analizar y valorar sus principales características y su evolución en el tiempo, identificando las causas del deterioro y desaparición del patrimonio salinero, evaluando la efectividad de las iniciativas, públicas y/o privadas, y de las figuras de protección, así como analizar las relaciones que establecen con su entorno próximo, con los núcleos de población y habitantes a los que sirven, la red de carreteas y caminos que las conectan y los ríos y mares que las proveen de materia prima. Finalmente, se ha establecido una sistemática integral de análisis, con el fin de poder actuar, a partir del conocimiento, a favor de la gestión, salvaguarda y pervivencia de los excepcionales valores culturales y naturales, que definen el carácter e identidad de estos singulares paisajes. ----------------------ABSTRACT----------------- The landscapes of this research have been created by the activity of saltworks, sites “where salt from sea water or certain springs is obtained, when water evaporates.” (RAE). They are places with unique characteristics, because of their natural and environmental values, as well as their cultural, historic and social values, their heritage and identity, “the result of the action and interaction of natural and human factors on the territory” (European Landscape Convention, 2000). There are many saltworks in many places around the world, but it is in the Iberian Peninsula where we find the highest concentration of salt industries within Europe and, therefore, the particular landscapes associated and created by them. It is as well the only European region where we can find inland saltworks with evaporation methods to obtain salt: the energies and natural circumstances used in them are sun, wind, gravity and relative humidity, favouring salt water evaporation, one of the main strategies of their functioning. This circumstance determines their geographic position in the territory and its dependence on seasonal climatic cycles, hydrological regimes, geological subsoil structure, geomorphology and human action to strengthen productive processes efficiency, creating an extensive and interesting natural and cultural heritage around them. Therefore, they are also cultural landscapes, result of a traditional salt production process and marketing, organized through the construction of certain preindustrial buildings scattered and connected in strategic inland and seaside spots. This thesis deals with the plight today’s salt landscapes are facing, particularly those within the Andalucian Region, since the middle of the 20th century undergoing an avid process of abandonment and disappearance, meaning a great loss for society of a cultural and natural heritage constructed along centuries, almost since the beginning of mankind. Among the diverse typologies of saltworks, the selection made consists on those inland and seaside ones, which use or have originally used traditional production techniques based on evaporation. The interest in this particular saltwork typology is based on the dependency relationships these industries establish with the environment and climate where they are located, in order to be able to exist and function. The main goal of this research has pursued to establish and define a global and inclusive territorial framework for Andalucian cultural saltworks landscapes, through direct observation carried out during fieldwork, analysis of texts, images, documents, graphs, words and open interviews. All of it has allowed to identify, classify, analyze and evaluate their main characteristics and evolution over time, identifying the causes of deterioration and disappearance of the saltworks heritage, assessing the effectiveness of public and private initiatives, and protection projects, as well as analyzing the relationships with their surroundings, population centers and residents they serve, road networks connecting them and rivers and seas supplying the raw material. Finally, a comprehensive analysis systematic has been established, in order to be able to take action, with knowledge as starting point, for the management, preservation and survival of the unique cultural and natural values that define the character and identity of these singular landscapes.

Changes in Petrophysical Properties of the Stone Surface due to Past Conservation Treatments in Archaeological Sites of Merida (Spain)

Petrophysical properties, such as porosity, permeability, density or anisotropy de-termine the alterability of stone surfaces from archaeological sites, and therefore, the future preservation of the material. Others, like superficial roughness or color, may point out changes due to alteration processes, natural or man-induced, for ex-ample, by conservation treatments. The application of conservation treatments may vary some of these properties forcing the stone surface to a re-adaptation to the new conditions, which could generate new processes of deterioration. In this study changes resulting from the application of consolidating and hydrophobic treatments on stone materials from the Roman Theatre (marble and granite) and the Mitreo’s House (mural painting and mosaics), both archaeological sites from Merida (Spain), are analyzed. The use of portable field devices allows us to perform analyses both on site and in la-boratory, comparing treated and untreated samples. Treatments consisted of syn-thetic resins, consolidating (such as tetraethoxysilane TEOS) and hydrophobic products. Results confirm that undesirable changes may occur, with consequences ranging from purely aesthetic variations to physical, chemical and mechanical damages. This also permits us to check limitations in the use of these techniques for the evaluation of conservation treatments.

New agri-environmental policies for the sustainability of mountainous olive farming. Evidences from Andalusia, Spain

La sostenibilidad de los sistemas olivareros situados en zonas de pendiente y montaña (SMOPS) en Andalucía se encuentra actualmente amenazada por las elevadas tasas de abandono que afectan a estos sistemas productivos. Así, la consumación de este proceso de abandono, no sólo pondría en peligro a las propias explotaciones, sino a todo el conjunto de bienes y servicios no productivos y al patrimonio cultural generado por este sistema productivo. En este contexto, la búsqueda de alternativas políticas enfocadas a revertir este proceso se erige como una necesidad categórica en aras de garantizar en el largo plazo la sostenibilidad de los olivares de montaña. Esta tesis pretende hacer frente a esta necesidad a través de la construcción de un marco político alternativo para los SMOPS, que permita la integración simultánea de todas las dimensiones que pueden influir en su desarrollo; esto es: el marco político actual, principalmente determinado por la Política Agraria Común (PAC) de la Unión Europea (UE); las preferencias de la sociedad hacia la oferta de bienes y servicios públicos generados por los SMOPS; y las preferencias y voluntad de innovación hacia nuevos manejos y sistemas de gestión de los agricultores y propietarios de las explotaciones. Para ello, se emplea una metodología de investigación mixta, que abarca la realización de cuatro encuestas (personales y online) llevadas a cabo a los agentes o grupos de interés involucrados directa o indirectamente en la gestión de los SMOPS –ciudadanos, agricultores y propietarios y expertos-; una profunda revisión de las herramientas de política agroambiental actuales y posibles alternativas a las mismas; y el desarrollo de nuevas estrategias metodológicas para dotar de mayor precisión y fiabilidad las estimaciones obtenidas a partir del Método del Experimento de Elección (MEE) en el campo de la valoración medioambiental. En general, los resultados muestran que una estrategia de política agroambiental basada en la combinación de los Contratos Territoriales de Zona Rural (CTZR) y el manejo ecológico supondría una mejora en la sostenibilidad de los sistemas olivareros de montaña andaluces, que, al mismo tiempo, propiciaría una mejor consideración de las necesidades y demandas de los agentes implicados en su gestión. Asimismo, los hallazgos obtenidos en esta investigación demandan un cambio de paradigma en los actuales pagos agroambientales, que han de pasar de una estrategia basada en la implementación de acciones, a otra enfocada al logro de objetivos, la cual, en el caso del olivar, se podría centrar en el aumento del secuestro de carbono en el suelo. Desde un punto de vista metodológico, los resultados han contribuido notablemente a mejorar la fiabilidad y precisión de las conclusiones estimadas a partir del MEE, mediante el diseño de un novedoso proceso iterativo para detectar posibles comportamientos inconsistentes por parte de los entrevistados con respecto a su máxima Disposición al Pago (DAP) para lograr la situación considerada como “óptima” en los olivares ecológicos de montaña andaluces. En líneas generales, el actual marco institucional favorece la puesta en práctica de la mayoría de las estrategias propuestas en esta tesis; sin embargo son necesarios mayores esfuerzos para reconducir los actuales Pagos Agroambientales y Climáticos de la PAC, hacia una estrategia de política agroambiental adaptada a las necesidades y requisitos del territorio en el que se aplica, enfocada al logro de objetivos y que sea capaz de integrar y coordinar al conjunto de agentes y grupos de interés involucrados -directa o indirectamente- en la gestión de los olivares de montaña. En este contexto, se espera que la puesta en práctica de nuevas estructuras y acuerdos de gobernanza territorial juegue un importante papel en el desarrollo de una política agroambiental realmente adaptada a las necesidades de los sistemas olivareros de montaña andaluces. ABSTRACT The long-term sustainability of Andalusian sloping and mountainous olive production systems (SMOPS) is currently threatened by the high abandonment rates that affect these production systems. The effective occurrence of this abandonment process is indeed menacing not only farms themselves, but also the wide array of public goods and services provided by SMOPS and the cultural heritage held by this production system. The search of policy alternatives aimed at tackling this process is thus a central necessity. This thesis aims to undertake this necessity by building an alternative policy framework for SMOPS that simultaneously integrates the several dimensions that are susceptible to influence it, namely: the current policy framework, mainly determined by the European Union’s (EU) Common Agricultural Policy (CAP); the social preferences toward the supply of SMOPS’ public goods and services; and farmers’ preferences and willingness to innovate toward new management practices in their farms. For this purpose, we put into practice a mixed-method strategy that combines four face-to-face and online surveys carried out with SMOPS’ stakeholders -including citizens, farmers and experts-; in-depth analysis of current and alternative agrienvironmental policy (AEP) instruments; and the development of novel methodological approaches to advance toward more reliable Discrete Choice Experiment’s (DCE) outcomes in the field of environmental valuation. Overall, results show that a policy strategy based on the combination of Territorial Management Contracts (TMC) and organic management would further enhance Andalusian SMOPS’ sustainability by simultaneously taking into account stakeholders’ demands and needs. Findings also call for paradigm shift of the current action-oriented design of Agri-Environmental-Climate Schemes (AECS), toward a result-based approach, that in the case of olive orchards should particularly be focused on enhancing soil carbon sequestration. From a methodological perspective, results have contributed to improve the accuracy and feasibility of DCE outcomes by designing a novel and iterative procedure focused in ascertaining respondents’ inconsistent behaviour with respect to their stated maximum WTP for the attainment of an ideal situation to be achieved in organic Andalusian SMOPS. Generally, the present institutional framework favours the implementation of the main policy strategies proposed in this thesis, albeit further efforts are required to better conduct current CAP’s agri-environmental instruments toward a territorially targeted result-oriented strategy capable to integrate and coordinate the whole set of stakeholders involved in the management of SMOPS. In this regard, alternative governance structures and arrangements are expected to play a major role on the process of tackling SMOPS’ agri-environmental policy challenge.

It is as well the only European region where we can find inland saltworks with evaporation methods to obtain salt: the energies and natural circumstances used in them are sun, wind, gravity and relative humidity, favouring salt water evaporation, one of the main strategies of their functioning. This circumstance determines their geographic position in the territory and its dependence on seasonal climatic cycles, hydrological regimes, geological subsoil structure, geomorphology and human action to strengthen productive processes efficiency, creating an extensive and interesting natural and cultural heritage around them. Therefore, they are also cultural landscapes, result of a traditional salt production process and marketing, organized through the construction of certain preindustrial buildings scattered and connected in strategic inland and seaside spots. This thesis deals with the plight today’s salt landscapes are facing, particularly those within the Andalucian Region, since the middle of the 20th century undergoing an avid process of abandonment and disappearance, meaning a great loss for society of a cultural and natural heritage constructed along centuries, almost since the beginning of mankind. Among the diverse typologies of saltworks, the selection made consists on those inland and seaside ones, which use or have originally used traditional production techniques based on evaporation. The interest in this particular saltwork typology is based on the dependency relationships these industries establish with the environment and climate where they are located, in order to be able to exist and function. The main goal of this research has pursued to establish and define a global and inclusive territorial framework for Andalucian cultural saltworks landscapes, through direct observation carried out during fieldwork, analysis of texts, images, documents, graphs, words and open interviews. All of it has allowed to identify, classify, analyze and evaluate their main characteristics and evolution over time, identifying the causes of deterioration and disappearance of the saltworks heritage, assessing the effectiveness of public and private initiatives, and protection projects, as well as analyzing the relationships with their surroundings, population centers and residents they serve, road networks connecting them and rivers and seas supplying the raw material. Finally, a comprehensive analysis systematic has been established, in order to be able to take action, with knowledge as starting point, for the management, preservation and survival of the unique cultural and natural values that define the character and identity of these singular landscapes.

Urban Archaeology in Madrid. Experiences and Opportunities to Understand Historical City

In 2015, it will be thirty years since Spanish Historic Heritage Law from 1985 was approved. The results after three decades under this law are necessarily positive and witness how the complex autonomous regional legislation has been promoted, guided and organized in this Heritage field. In addition, the law enforcement has brought into the scene how the numerous public and private initiatives involved in caring, managing, protecting and restoring our cultural heritage have been channeled and regulated, as well as monitoring the impact these initiatives produce on urban archaeology. During this long period of Spanish recent history, cultural heritage -understood as an important development tool, especially when related to cultural tourism- has succeeded in channeling resources for developing the historical research projects, both documental and archaeological, that the Spanish monumental urban ensembles were requiring. In this context, the case of the city of Madrid is a clear example of the significant development that urban Historical Archaeology has experienced in Spain over the last thirty years, especially when dealing with the study of the Middle Ages (8th to 15th centuries) and the Modern Age (16th to 18th centuries). Given the number of interventions and the important results obtained by many of them, Madrid urban archaeology is an extraordinary example of the consequences of implementing new management models, changing criteria and operating procedures, and also, of course, of the conflicts and debates raised regarding heritage, as well as the importance these interventions have implied, which is the main aim of this work.
