COST Action Urban Agriculture Europe Training School «Urban agriculture inside the city:alternatives for vacant lots and public space»

The third Training School of the Action took place in Vitoria-Gasteiz (Basque country, Spain) from 24th to 26th September 2014. Vitoria-Gateiz has experimented an important urban outgrowth in the last decade, mainly through the planning and development of two new neighborhoods, Zabalgana and Salburúa, situated at the eastern and western border of the city, by the Greenbelt. These new development are well-equipped and designed according to sustainability principles. Nevertheless, among the main problems they present is their over-dimensioned public space, which creates some areas lacking enough density and mix of uses. On the other hand it is very expensive for the municipality to maintain these public space with the high Vitorian urban standards for public space. The proposed solution for this problem is a strategy of "re-densification" through the insertion of new uses The debate has arisen about which are the most adequate uses to insert in order to get an increasing of urban vitality, specially considering that housing has reached its peak and that Vitoria-Gasteiz is well served with social and sport amenities. The main goal of the TS was to offer an opportunity for the reflection about how urban agriculture might be an optimal alternative for the re-qualifying of this over-dimensioned public space in the new neighbourhoods, especially considering it synergic potential as a tool for production, leisure and landscaping, including the possibility of energy crops within the limits of urban space. Continuity with rural and natural surrounding area through alternatives for urban fringe at the small scale is a relevant issue to be considered as well within the reflection. Taking Zabalgana neighbourhood as a practical field for experiment, the Training School is conceived as a practical and intensive design charrette to be held during a whole day after two days of local knowledge-deepening through field visits and presentations.

Deployment of urban agriculture in East Lima, Peru.

Urban agriculture in Lima has been promoted by the project Farmers in the city encompassed in the Urban harvest program promoted by the Consultive Group on International Agricultural Research (CGIAR). The validation of the effectiveness of the project Farmers in the city can only be confirmed by maintenance over the time the deployment of the project goals. The project Farmers in the city was carried out by the International Potato Center (CIP) and GESPLAN research group of the Technical University of Madrid. The project was conducted at the East Cone of Lima, Peru, from 2006 to 2008. This communication shows the situation 5 years later. In order to know the current situation all the members of Cosanaca producer association, which was created under the project, have been interviewed. Besides, an expert panel was carried out with the responsible of the urban agricultural office of the municipalities that participate in the project. The results show that Cosanaca has duplicated the number of producers and that the municipalities have increased the number of workers.

Urban agriculture in the new framework of green cities.

Urban Agriculture was a common practice in the old times. However after a period of low interest by urban population there is a movement of renaissance of urban agriculture especially in the new megalopolis. It is important to understand the role of UA in the new framework, and the interface of urban and rural agricultures, with their comparative advantages. Thus, we describe the impact of UA in several scenarios: political, socioeconomic and environmental. As a consequence several actions should be developed for improving the situation, with the stimulus to UA: urban planning, food value chain, appropriate technology, education and extension services, entertainment and leisure, selection of botanic varieties and agrochemical inputs, design and landscape and good farming practices. As a complement, there is an analysis of the Urban Greening Value Organization in our society. In the paper there is a description of the situation of urban agriculture in Spain (located mainly in roofs, walls, indoor and ground places) the existence of local regulations, barriers and opportunities in the new situation. Due to the social dimension of urban agriculture there are some comments about the role of the more significant stakeholders, and the goals and the structure of the neighbor communities.

Urbanism and dictatorship: perspectives of the field of urban studies

In 1933 public letter to Wilhelm Furtwängler, Joseph Goebbels synthesized the official understanding of the link between politics, art and society in the early steps of the Third Reich. By assuming the ethos of art, politics acquired a plastic agency to mold its objects —population and the state— as a unified entity in the form of a ‘national-popular community’ (Volksgemeinschaft); in turn, by infusing art with a political valence, it became part of a wider governmental apparatus that reshaped aesthetic discourses and practices. Similar remarks could be made about the ordering of cities and territories in this period. Dictatorial imaginations mobilized urbanism —including urban theory, urban design and planning— as a fundamental tool for social organization. Under their aegis the production of space became a moment in a wider production of society. Many authors suggest that this political-spatial nexus is intrinsic to modernity itself, beyond dictatorial regimes. In this light, I propose to use dictatorial urbanisms as an analytical opportunity to delve into some concealed features of modern urban design and planning. This chapter explores some of these aspects from a theoretical standpoint, focusing on the development of dictatorial planning mentalities and spatial rationalities and drawing links to other historical episodes in order to inscribe the former in a broader genealogy of urbanism. Needless to say, I don’t suggest that we use dictatorships as mere templates to understand modern productions of space. Instead, these cases provide a crude version of some fundamental drives in the operationalization of urbanism as an instrument of social regulation, showing how far the modern imagination of sociospatial orderings can go. Dictatorial urbanisms constituted a set of experiences where many dreams and aspirations of modern planning went to die. But not, as the conventional account would have it, because the former were the antithesis of the latter, but rather because they worked as the excess of a particular orientation of modern spatial governmentalities — namely, their focus on calculation, social engineering and disciplinary spatialities, and their attempt to subsume a wide range of everyday practices under institutional structuration by means of spatial mediations. In my opinion the interest of dictatorial urbanisms lies in their role as key regulatory episodes in a longer history of our urban present. They stand as a threshold between the advent of planning in the late 19th and early 20th century, and its final consolidation as a crucial state instrument after World War II. We need, therefore, to pay attention to these experiences vis-à-vis the alleged ‘normal’ development of the field in contemporary democratic countries in order to develop a full comprehension thereof.

Reversible Urban Entities. Improving public-to-private continuity.

The aim of this paper is to call into question those typologies conventionally used in developing the post-industrial urban fabric (streets, cityblocks, slabs, etc.), often catering to urban designs based on speculative interests and completely overlooking community interests. By defining the concepts of ?postpublic space? and ?reversible urban entities? and illustrating them with an exemplary case of Spanish residential architecture from the 1960s, we establish one possible way of tackling contemporary urban-residential projects. This alternative approach considers the relationship between residential systems and open space systems and promotes the continuity and/or alternation of scales between house and city in an effort to improve the urban quality of life for residents and external users.

La metáfora. Herramienta característica de renovación arquitectónica tras el movimiento moderno

Esta tesis estudia el papel de la metáfora como instrumento arquitectónico en el debate y las propuestas para superar la ortodoxia de la arquitectura moderna a partir de mediados del siglo XX. En arquitectura, la utilización del procedimiento que constituye la metáfora se apoya en una consideración semántica de la arquitectura y se ha usado constantemente a lo largo de la historia para desarrollar nuevas propuestas, basándose en la comparación con modelos conocidos. En este trabajo se examina la notable presencia que adquirió este instrumento en las propuestas críticas a la arquitectura moderna ortodoxa, debido a la importancia que tuvieron los aspectos semánticos en el debate sobre la continuidad y vigencia de los postulados de la arquitectura moderna. Con este estudio se ha indagado sobre las razones y la frecuencia con las que aquellos arquitectos que adoptaron una actitud crítica hacia la arquitectura moderna se refirieron a las relaciones metafóricas en sus propuestas alternativas. Para mostrar cómo las metáforas formaron parte de los mecanismos de cambio de la arquitectura en este periodo, recuperando un mayor potencial creativo para abordar los proyectos arquitectónicos, se han estudiado una serie de ejemplos pertinentes y relevantes. En cada uno de los capítulos se han analizado las objeciones más importantes que fueron planteadas frente a la arquitectura moderna por un arquitecto o grupo de arquitectos, seleccionados entre aquéllos que tomaron parte en este debate, y se estudia la inclusión de la metáfora en las alternativas que propusieron en cada caso. Además de una actitud crítica con la arquitectura moderna, todos los arquitectos seleccionados comparten una consideración semántica de la arquitectura y han expuesto sus ideas y posturas tanto en obras proyectadas y construidas, como en escritos o comentarios sobre su manera de entender y proyectar arquitectura. Esta doble producción ha permitido analizar, comparativamente, el papel de la metáfora en sus enfoques y propuestas críticas y en la realización de sus obras como alternativas a las mismas. Al mismo tiempo, la investigación profundiza en el conocimiento de la utilización de la metáfora como herramienta arquitectónica. A través del recorrido por las distintas maneras de entender este instrumento que pueden observarse en algunos de los arquitectos de la segunda mitad del siglo XX, se exponen tanto las posibilidades como los aspectos más críticos de la utilización de la metáfora en arquitectura. La variada utilización de la noción de metáfora en arquitectura se ve reflejada en las diversas consideraciones que hacen de la misma los arquitectos estudiados. La tesis se ha ocupado de distinguir cada uno de estos enfoques, haciéndose eco de la pluralidad con la que puede abordarse el concepto de metáfora de manera general y en arquitectura en particular. Así, algunos arquitectos del Team 10, la utilizan como un instrumento de ampliación y renovación semántica de la arquitectura moderna, que propone una síntesis de lo viejo y lo nuevo. Para Robert Venturi, se trata de un recurso con capacidad de persuadir y recrear, renovando semánticamente la arquitectura. Charles Jencks considera que es un procedimiento semántico esencial de la arquitectura, olvidado por los arquitectos modernos, cuya recuperación supone un rasgo diferencial de la arquitectura posmoderna respecto a la moderna. Para Aldo Rossi, es una manera de materializar las relaciones analógicas que constituyen su propuesta para proyectar una arquitectura de racionalismo exaltado frente a un racionalismo convencional. Peter Eisenman la valora porque inventa otras arquitecturas diferentes a las preconcebidas anteriormente, a pesar de que rechaza su capacidad representativa y expresiva. Rafael Moneo la utiliza para contraponerse al determinismo, como instrumento de innovación de la forma arquitectónica que construye una dinámica entre la contingencia y la necesidad. Finalmente, para Frank Gehry supone un procedimiento creativo y subjetivo con el que enfrentarse tanto a la arquitectura moderna como a la posmoderna con una arquitectura nueva y abierta a referencias inusuales. De esta manera, a través de los distintos capítulos, el estudio pretende componer un mosaico de posturas que manifieste los vínculos y las diferencias existentes entre estos arquitectos con relación a los temas estudiados: crítica y alternativas a la arquitectura moderna, semántica de la arquitectura, metáfora y otros conceptos relacionados. A su vez, la aparición continuada de la metáfora en los diferentes capítulos, y de los temas con los que está relacionada, manifiesta el protagonismo de esta herramienta arquitectónica en las propuestas de evolución y cambio de la arquitectura del periodo estudiado. ABSTRACT This thesis studies the role of the metaphor as an architectural tool in the debate and proposals to overcome the orthodoxy of modern architecture that took place since the middle part of the Twentieth Century. In architecture, the usage of the process which the metaphor constitutes is based in a semantic consideration of architecture and historically it has been used many times to develop new proposals, always based in the comparison with known models. This work examines the significant presence that this tool acquired in the proposals critical with orthodox modern architecture, due to the importance that the semantic aspects had in the debate on the continuity and validity of modern architecture’s postulates. This study also looks into the motives and frequency that those architects which adopted a critical attitude towards modern architecture alluded to the metaphorical relations in their alternative proposals. To demonstrate how during that period metaphors were imbued in the mechanisms of change of architecture, recovering a higher creative potential to approach architectural projects, a series of pertinent and relevant examples are studied. Each chapter examines the most important objections on modern architecture made by an architect or group of architects, selected among those who participated in this debate, and studies the inclusion of metaphor in the alternatives proposed in each case. Besides a critical attitude towards modern architecture, all the selected architects share a semantic consideration of architecture and have exposed their ideas and postures through projected and finalized works as in writings or commentaries on their way of understanding and projecting architecture. This double production allowed to analyse, in a comparatively manner, the role of metaphor in their approaches and critical proposals as in the execution of their works. At the same time, the research conducted further analyses the body of knowledge on the usage of metaphor as an architectural tool. By looking over the different ways some of the architects of the second half of the Twentieth Century understood this tool, both the possibilities and the most critical aspects of the usage of the metaphor in architecture can be exposed. The various usages of the notion of metaphor in architecture are reflected in the multiple considerations done about it by the selected architects. This thesis differentiates each one of those approaches, echoing the plurality with which the concept of metaphor can be addressed both in broader terms and more particularly in architecture. In this sense, some architects of Team 10 used it as a mean of semantic extension and renewal of modern architecture, proposing a synthesis between the old and the new. For Robert Venturi it is a resource with the capacity to persuade and recreate, semantically renewing architecture. Charles Jencks considers it an essential semantic procedure of architecture, forgotten by the modern architects, and which recovery represents a differential trait of post-modern architecture in relation to modern architecture. For Aldo Rossi, is a way of materializing the analogical relations which represent his proposal to project architecture of exalted rationalism as opposed to a more conventional rationalism. Peter Eisenman values it because it invents other architectures different from the preconceived before, even if he refuses its representational and expressive capacity. Rafael Moneo uses it to counter determinism, as an innovation tool of the architectonical form which generates dynamics between contingency and necessity. Finally, for Frank Gehry it supposes a creative and subjective process to face both modern architecture and post-modern architecture with a new architecture open to unusual references. As such, through its different chapters, this study aims to compose a mosaic of postures which expresses the links and the differences between those architects in relation to the topics examined: criticism and alternatives to modern architecture, semantics of architecture, metaphor and other related concepts. At the same time, the continuous presence of the metaphor in the different chapters, and of the issues it relates to, shows the importance of this tool in the proposals of evolution and change of architecture in the period considered.

Nagele, a green building without a roof

The paper shows the design process of Nagele, a Dutch modernist agrarian settlement designed during the Post-Second World War period by the internationally recognized group of architects De 8 en Opbouw: Rietveld, Van Eesteren, Merkelbach, van Eyck, Bakema, Stam, Ruys, etc. It is located in the Noordoostpolder (NOP), in the Flevoland province, which was entirely reclaimed from the sea. The country planning of the Noodoostpolder reveals a high rationalization in the disposal of roads, canals, cities, agrarian land and forests, which can be an inspiration for the cities of today. The configurational elements of Nagele must be understood in terms of their relationship to the overall system of the polder. Important territorial principles in structure, form and landscape can be seen in the project of Nagele. This relationship is an additional example of the continuing transformation that the entire length and breadth of The Netherlands in subjected to. The research developed to date reveals a plan which shows the evolution of functionalistic paradigm at the CIAM postwar congresses. The particular case of Nagele points to the incorporation of human scale, green design and social co-existence. The source of these theories mainly came from Aldo van Eyck, who played an important role during the second phase of design. The research will be developed analyzing his drawings and texts and will show the way his theories appear in the project. Can Nagele be a materialization of Van Eyck¿s ideas? Nagele constitutes one of the most outstanding contributions to modern urban planning as far as both urbanism and landscape, are at the service of human well-being. Not only were urban independently designed parts, but their relationships also formed a perfect urban whole.

Arsenic, antimony and selenium in urban soils: potential risks for human health in urban gardening

The benefits of urban agriculture are many and well documented, ranging from health improvement to community betterment, more sustainable urban development and environment protection. On the negative side, urban soils are commonly enriched in toxic trace elements that have accumulated over time through the deposition of atmospheric particles (generated by automotive traffic, heating systems, historical industrial activities and resuspended street dust), and the uncontrolled disposal of domestic, commercial and industrial wastes. This in turn has given rise to concerns about the level of exposure of urban farmers to these elements and the potential health hazards associated with this exposure. Research efforts in this field have started relatively recently and have almost systematically omitted the influence of Sb and Se, and to a lesser extent of As, although all three have proven toxic effects.

Evaluation of Development Projects: a Process-Centered Approach in the Outskirts of Lima, Peru.

Development cooperation projects work with people involved in processes of change and social transformation. While the main objective of the intervention is the development process itself, the project?s quality will be determined by the way of implementing it. Its success lies in the sustainability of the generated processes and the connection with them by the involved actors. The evaluation analyses both aspects. This article examines the evaluation, under a process approach, of a project on urban agriculture in Lima (Peru). The results show that the use of this approach, which combines different evaluation tools, allows the identification and analysis of the processes with the involved members, providing a better understanding of the real sustainability of the results.

Un entendimiento infraestructural del proyecto arquitectónico

Un entendimiento infraestructural del proyecto arquitectónico Este trabajo de tesis reivindica la pertinencia de la lógica infraestructural como herramienta de proyecto arquitectónico en el territorio urbano contemporáneo, a través del relato del tránsito que se produce entre las décadas de 1960 y 1970 y el final del siglo XX, desde unos sistemas urbanos centrales, vectoriales y ‘modernos’ hacia unos sistemas policéntricos, organizados según modelos de campos y ‘contemporáneos’. Las infraestructuras han sido tradicionalmente objeto de interés para generaciones de arquitectos y urbanistas que, bien desde su condición plástica más pregnante, bien desde una intuición de su capacidad organizativa, han sido fascinados por la irrupción en el territorio de estos elementos generalmente ajenos al proyecto arquitectónico. Los proyectos que durante décadas han explorado la posibilidad de habitar estas grandes estructuras, o de proyectar con su lenguaje y su escala, han resultado en un acercamiento a la capacidad de lo infraestructural como herramienta de proyecto limitada a cuestiones morfotipológicas. Sin embargo, a partir de un estudio de la infraestructura ‘clásica’ como aquella resultado de la manifestación de las redes de abastecimiento y conectividad básicas, se desvela una naturaleza de lo infraestructural que trasciende su expresión formal conocida y explora su capacidad performativa, como sistema de relaciones, como orden topológico, como soporte flexible para la actividad espontánea y no anticipada. A partir del trabajo de diversos autores y de una selección de proyectos de distinta índole –la mayoría no construidos– se muestra cómo la irrupción de una conciencia relacional, así como la problemática moderna de afrontar los procesos de generación de una ‘nueva ciudad para una nueva sociedad’, motivan la búsqueda de sistemas de generación y control de ‘forma colectiva’ adecuados a un modelo urbano contemporáneo. Transitando por los escritos de Fumihiko Maki en Investigations in Collective Form, Reyner Banham en Megastructure, o Shadrach Woods en The Man in the Street durante los 60 y 70 y, más recientemente, de Stan Allen en Points + Lines, Edward Soja en Postmetropolis o Frei Otto en Occupying and Connecting, se traza esta historia semántica de lo infraestructural desde lo tipológico hasta una noción ampliada que resulta pertinente para operar en el territorio contemporáneo postmetropolitano. Para ello el trabajo plantea, por un lado, la descripción del contexto urbano que podemos asumir como contemporáneo, su evolución y sus características principales. Por otro lado, se explora la formación de esta noción de entendimiento infraestructural en las últimas décadas desde enfoques complementarios. Una introducción describe las condiciones de contexto en las que este estudio doctoral adquiere su pertinencia: el tránsito relativamente reciente desde un modelo vectorial y clásico de ocupación del territorio, al modelo contemporáneo disperso y policéntrico propio del modelo de campos. Un bloque central de tres capítulos analiza ‘lo infraestructural’ como expresión de una arquitectura de las relaciones, como soporte para una sociedad en cambio y como lógica proyectual, no ligada a una forma dada. La última parte, a modo de epílogo, describe el territorio urbano contemporáneo, sus cualidades básicas y la capacidad de las lógicas infraestructurales enunciadas en los capítulos anteriores para operar en él. Un último apartado de conclusiones, establece las bases de una línea de investigación abierta acerca de la operatividad actual de estos sistemas en el proyecto de arquitectura. ABSTRACT An infrastructural understanding of architectural design This thesis project claims for the suitability of infrastructural logics as a design tool within contemporary urban territories. This claim is illustrated by means of a report on the transit between the 60–70’s decades and the end of the 20th century, ranging from vector, central, ‘modern’ urban systems, towards polycentric ‘contemporary’ urban patterns, arranged following field models. Infrastructures have been traditionally on the spot for generations of architects and urban planners who, due to either their aesthetical condition, or an intuition of their organizational capacity, have been fascinated by the bursting of these elements in the territory. Projects which have explored the possibility to inhabit these huge structures, or to design with its language or scale for decades, have turned out to be always limited to morphological-typological issues. However, from the base of a research on ‘classic’ infrastructure –understood as the outcome of supplies and connectivity basic networks– a new nature of infrastructure is revealed, going beyond its known formal expression and exploring its potential to perform as a system of relationships, as a topological pattern, or as a flexible support for spontaneous and unanticipated activity. The breakthrough of a relational consciousness, as well as the modern concern about the generation of ‘a new city for a new society’ are shown, through the works of several authors and a selection of heterogeneous mostly-unbuilt projects. This semantic history of infrastructures, regarding not only typologies but also a broader concept able to operate in contemporary postmetropolitan territory, is drawn by following the paths of Fumihiko Maki in Investigations in Collective Form, Reyner Banham in Megastructure, or Shadrach Woods in The Man in the Street during the 60’s and 70’s and, lately, those of Stan Allen in Points + Lines, Edward Soja in Postmetropolis or Frei Otto in Occupying and Connecting. In order to do so, this thesis project sets, on one hand, a description of the urban context which can be assumed as contemporary, as well as its evolution and main features. On the other hand, complementary approaches help go deep into how this notion of infrastructural insight within the last decades has been created. An introduction describes the contextual conditions for this thesis project to become relevant: the relatively recent transit from a classic spatial occupation pattern, to the contemporary, disperse and polycentric pattern inherent to field models. A three-chapters core analyzes the infrastructures as the expression of an architecture of relations, as well as a support for a changing society and as a formless design logic. The last part, an epilogue, describes the urban contemporary territory and the suitability of the infrastructural logics to operate in it. A final conclusive section, lays the foundations for an open line of research on present functionality of these systems in architectural designs.

El Parque Agrario: estructura de preservación de los espacios agrarios en entornos urbanos en un contexto de cambio global

La propuesta del análisis de la figura de Parque Agrario en el ámbito español surge ante la constatación de que un nuevo paradigma está aconteciendo a escala estatal. Diversos focos se encuentran trabajando en paralelo, y de forma participada, en pos de la reformulación de las políticas públicas relacionadas con la agricultura periurbana. Estos focos ven en la figura de Parque Agrario un instrumento territorial que permite mejorar la sostenibilidad y cohesión territorial a través de la defensa de la gobernanza alimentaria local, sin olvidar la necesidad de conservación de los recursos naturales y el patrimonio paisajístico, junto a la prestación de múltiples servicios de los ecosistemas de estos ámbitos a la ciudadanía. Complementariamente, se empieza a vislumbrar el papel que esta figura puede desempeñar como herramienta de desarrollo territorial de los sistemas agrarios periurbanos, clave ante los efectos de carácter local que la globalización ejerce en estos territorios. La figura de Parque Agrario es una estructura que actúa bloqueando la base territorial, favoreciendo el desarrollo de la actividad agraria. Su mayor potencial es el de convertir el factor “proximidad urbana” de una amenaza a una oportunidad de desarrollo local endógeno que permita la continuidad de la agricultura, de los agricultores y del espacio agrario. La peculiaridad del Parque Agrario es que no es una figura al uso, estructurada y reglada por una legislación, sino que se trata de una iniciativa ad hoc, específica para cada caso, orientada a cumplir determinados objetivos de dinamización agraria, protección urbanística y valorización territorial. A pesar de la existencia de diversas definiciones y aportaciones sobre diferentes aspectos de la figura, no existe un análisis complejo de la misma en todas sus dimensiones, ni una tentativa de descripción de un modelo global y unitario del caso español y de sus potenciales resultados. Tampoco se han analizado en profundidad sus “invariantes” que se muestran como los elementos estructurantes del proyecto, capaces desarrollarse de forma diversa, de alcanzar diferentes niveles de complejidad, y de materializarse en función a las posibilidades que permita el marco normativo y legal. Por tanto, se plantea como objetivo principal de la tesis la definición de un modelo conceptual de Parque Agrario español, capaz de ser articulado e institucionalizado mediante un proceso de gobernanza, y que, como condición sine qua non sea duradero en el tiempo. Para poder llegar a describir un modelo colectivo se realiza, en primer lugar, un análisis genealógico que permita analizar sistemáticamente las propuestas desarrolladas en el ámbito español y los casos para establecer la existencia de una continuidad en la idea de Parque Agrario en las propuestas desarrolladas durante los últimos 25 años—sus invariantes—, y analice todos aquellos elementos que han ido enriqueciendo la figura en cada experiencia —sus variantes. Este análisis, además, ofrece como aportaciones el árbol genealógico y los mapas de dispersión de la figura y el primer catálogo de propuestas de Parque Agrario materializadas en proyecto. El resultado de la inducción de los datos obtenidos en el análisis genealógico es el modelo conceptual de Parque Agrario, que se define como una estructura orgánica de planificación-gestión-gobierno del territorio capaz de adaptarse a las necesidades específicas de todo sistema agrario periurbano que requiera la articulación-institucionalización de esta figura en él. Una vez descrito el modelo, se contrasta su fiabilidad mediante su aplicación como metodología de caracterización y evaluación de dos estudios de casos: uno exitoso, el Parque Agrario del Baix Llobregat, y uno frustrado, la propuesta de Parque Agrario de la Vega de Granada. ------------------------------------------------------ ABSTRACT -------------------------------------------------------------------- The proposed analysis of the figure of Agrarian Park in the Spanish sphere arises from the awareness that a new paradigm is happening at the state level. Different focuses are working in parallel, under participated programs, after the reformulation of public policies related to urban agriculture. These areas understand the figure of Agrarian Park as a territorial instrument for improving sustainability and territorial cohesion through the defense of local food governance, considering the need for conservation of natural resources and landscape heritage together with the multiple ecosystem services provided by these areas to the public. Additionally, the role that this figure can play as a tool for territorial development of peri-urban agrarian systems, which are key to the local effects that globalization has on these territories, is staring to be envisioned. The figure of Agrarian Park is a structure that works by blocking the territorial base to encourage the development of agrarian activity. Its greatest potential is to convert the threat of "urban proximity" into an opportunity for an endogenous local development that allows the persistence of agriculture, farmers and the agrarian space. The uniqueness of the Agrarian Park is that it is not a standard figure, structured and regulated by legislation, but rather an ad hoc initiative, specific to each case, designed to meet certain objectives of agrarian revitalization, urban protection and territorial enhance. Despite the existence of several definitions and contributions on different aspects of the figure, there is a lack of a complex analysis of it in all its dimensions, missing any attempt to describe a global and unitary model of the Spanish case and its potential outcomes. Its "invariants” have neither been evaluated in depth, shown as the structural elements of the project able to be developed in different ways, to achieve numerous levels of complexity, and to be materialized according to the possibilities allowed by the regulatory and legal framework. Therefore, the definition of a conceptual model of Spanish Agrarian Park able to be articulated and institutionalized through a process of governance, and durable over time as a sine qua non requisite, it is proposed as the main aim of the thesis. To get to describe a collective model, a genealogical analysis that systematically analyzes the proposals and cases developed in the Spanish field is undertaken to verify the existence of a continuity of the idea of Agrarian Park on the proposals developed during the past 25 years -invariants-, and evaluate all the elements that have enriched this figure in each experience - variants. This analysis also provides as inputs a family tree, maps of dispersion of the figure and the first catalog of Agrarian Park proposals materialized into projects. The result of inducting the data obtained in the genealogical analysis is the Conceptual Model of Agrarian Park, defined as an organic planning-management-government structure of the territory able to adapt to the specific needs of all peri-urban agrarian systems that require the articulation-institutionalization of this figure in it. Having described the model, its reliability is tested by applying it as a methodology for characterization and evaluation of two case studies, one successful, the Baix Llobregat Agrarian Park, and one frustrated, the proposed Agrarian Park de la Vega of Granada.

Spatial Planning Measures for the Enhancement of Urban Resilience Against Flooding Risk

Dentro del campo de la ciudad como lugar se analiza el concepto de planificación territorial y planeamiento espacial. Flooding is one of the main risks associated to many urban settlements in Spain and, indeed, elsewhere. The location of cities has traditionally ignored this type of risk as other locational criteria prevailed (communications, crop yields, etc.). Defence engineering has been the customary way to offset the risk but, nowadays, the opportunity costs of engineering works in urban areas has highlighted the interest of “soft measures” based on prevention. Early warning systems plus development planning controls rank among the most favoured ones. This paper reflects the results of a recent EU-financed research project on alternative measures geared to the enhancement of urban resilience against flooding. A city study in Spain is used as example of those measures.

El territorio en el sistema agroalimentario: el tramo medio del valle del Duero 1900-2015

La lectura histórica del territorio en relación con el sistema agroalimentario aporta elementos claves para reconstruir el sistema territorial, aprovechando la oportunidad que ofrece un renovado interés por la alimentación local y sostenible. El análisis histórico transdisciplinar incorpora variables espaciales, económicas, energéticas, urbanísticas, agronómicas y nutricionales y se centra en el tramo medio del valle del Duero (Castilla y León, España). Se trata de un territorio tradicionalmente agrícola, donde un producto de la tierra -el vino- es motor de innovación y ha transformado paisajes y estructuras. Aún así, se enfrenta a un desarrollo desigual e ilustra las contradicciones del mundo rural en un contexto alimentario globalizado. El análisis de la región desde 1900 permite constatar la relación entre la organización del territorio, el sistema agroalimentario, y cada una de las etapas nutricionales: a) la superación de la desnutrición está asociada a una agricultura familiar y al territorio de proximidad, que persiste en la zona hasta 1950; b) el modelo de consumo de masas y sobrealimentación, se basa en una agricultura industrializada y un territorio polarizado ligado al desarrollismo, que se extiende hasta 1985; c) finalmente, el modelo de consumo segmentado se apoya en una agricultura terciarizada y un territorio de enclaves en un contexto de globalización, que dura hasta nuestros días. En la última fase aparecen nuevos modelos alternativos de reconstrucción territorial con sistemas emergentes que reconectan campo y ciudad, consumo y producción desde sistemas de alimentación sostenible. Conviven dos tendencias: una hacia la jerarquización y el productivismo tecnificado y otra hacia la multifuncionalidad y la recampesinización que se reapropia de las innovaciones técnicas. La adaptación a las condiciones locales y aprovechar los recursos endógenos son elementos clave de sostenibilidad ambiental y social. Incorporar la alimentación en la planificación urbana y territorial desde una perspectiva agroecológica reduciría la insostenibilidad del sistema alimentario. Las propuestas de ordenación han de tener en cuenta la tipología de municipios, sus interrelaciones, las características agrológicas y productivas, la relación del muncipcon los núcleos de referencia y con las poblaciones que concentran las necesidades de alimentación. Se debe considerar asimismo la disponiblidad de infraestructuras, de equipamientos y de capital humano y relacional para fijar cadena de valor local. La ordenación urbanística cuenta ya con mecanismos como la clasificación del suelo, la regulación de usos y el diseño de redes de equipamientos que inciden sobre la autonomía de los sistema de alimentación locales y permiten fomentar la biodiversidad y las variedades locales. Son mecanismos insuficientemente aprovechados. Una adecuada utilización de los instrumentos de ordenación existentes, junto con el desarrollo de otros nuevos mejorarían de forma significativa la resiliencia de los sistemas agroalimentarios locales. ABSTRACT The historical review of the relationship between territory and agrifood system provides key lessons to help rebuild the territorial fabric, seizing the opportunity offered by a renewed interest in local and sustainable food. The historical transdisciplinary analysis spans spatial, economic, energy, agronomic and nutritional variables, focuses on the middle reaches of the Douro valley (Castilla y Leon, Spain). This a traditionally agricultural region, which has managed to turn a land product – the wine– into an engine of innovation which has transformed landscapes and structures. Even so, it faces the challenges of uneven development and illustrates the contradictions of the rural world in a globalized context. After the analysis of the evolution of the region since 1900, it can be concluded that the territory has been organized over time according to three models of food system that are in turn linked to different nutritional stages: a) the nutritional stage of overcoming malnutrition is related to family agriculture and a territory of proximity, which persists in the studied area until 1950; b) the model of mass consumption and overeating, was built on an industrialized agriculture and a polarized territory with unhindered development, which runs until 1985; c) and, finally, the model of consumer segmentation associated with terciarized agriculture and enclave territories in the context of globalization, which lasts until present time. During this last stage new alternative models of small-scale territorial reconstruction appear, linked to emerging systems that, based on sustainable food systems, reconnect city and countryside, consumption and production. Actually two trends coexist: one towards hierarchisation and tech-based productivism, and another one towards multifunctionality and peasantization that reappropriates technical innovations. The adaptation to local conditions taking advantage of local resources is a key element of environmental and social sustainability. Integrating food into urban and regional planning from an agroecological perspective would help reduce the current unsustainability of the food system. Planning proposals for municipalities need to consider their typology, agrological characteristics, productive capacity, links to other municipalities, proximity to reference nodes and population concentrations with food demands that need to be met. Availability of infrastructure, facilities, as well as human and relational capital to establish and reinforce local value chains is another aspect to consider in planning proposals. Spatial and urban planning are already equipped with mechanisms, such as land classification and the design of facilities’ networks, that affect the autonomy and stability of local food systems and can support biodiversity and adoption of local varieties. We are, however, missing opportunities. An adequate use of existing planning tools and the development of new ones could significantly improve the resilience of local agrifood systems.

Jacques Tati : vivienda experimental y espacio de trabajo a mediados del siglo XX

La obra fílmica del director francés Jacques Tati podría considerarse como el perfecto reflejo del paradigma edificatorio de mediados del siglo XX en plena posguerra europea, una época ávida de transformaciones de las que el cine supo hacerse eco. Particularmente, el cine de Tati refleja las preocupaciones del ciudadano europeo de posguerra sobre las consecuencias de las masivas construcciones erigidas en sus devastados núcleos urbanos y la puesta en práctica de la ciudad funcional propuesta por la Carta de Atenas (1931). Pero, además, el análisis del cine de Jacques Tati permite un acercamiento a la modernidad desde diversos puntos de vista como la movilidad, el diseño urbano, las nuevas construcciones, los espacios de trabajo en los nuevos distritos terciarios, la vivienda -tradicional, moderna y experimental- o el diseño mobiliario en la posguerra. A través de su alter ego -Monsieur Hulot- Tati interacciona curioso con las nuevas construcciones geométricas de paños neutros y cuestiona su ruptura con la tradición edificatoria francesa, enfatizando la oposición entre el pasado nostálgico y la modernidad de las décadas de los 50 y 60, salpicadas por el consumismo feroz del recién estrenado estado de bienestar. La confrontación funcional, volumétrica, estética e incluso cromática entre ambos mundos construidos –el tradicional y el moderno- invita al espectador a un ejercicio de reflexión y crítica sobre la arquitectura moderna de este período en Europa. En particular, la mirada cinematográfica de Tati se centra en dos conceptos fundamentales. Por una parte, su atención se dirige a la famosa casa mecanicista Le Corbuseriana materializada en la ultra-moderna casa Arpel (Mon Oncle, 1958) y proyectada en la misma época en la que se desarrollaban importantes prototipos de vivienda experimental como la Casa de Futuro de Alison y Peter Smithson o las viviendas de Jean Prouvé. Debe ponerse de manifiesto que la crítica de Jacques Tati no se centraba en la arquitectura moderna en sí misma sino en el empleo erróneo que los usuarios pudieran hacer de ella. Por otro lado, Tati centra su atención en el prisma miesiano a través de los bloques de oficinas que conforman la ciudad de Tativille en Playtime (1967). Se trataba de una gran ciudad moderna construida explícitamente para el rodaje de la película y basada en los casi idénticos tejidos urbanos residenciales y terciarios ya en funcionamiento en las principales capitales europeas y norteamericanas en aquellos años. Tativille funcionaría como una ciudad autónoma disponiendo de diversas instalaciones y con el objetivo de integrarse y consolidarse en la trama urbana parisina. Lamentablemente, su destino al final del rodaje fue bien distinto. En definitiva, el análisis de la producción fílmica de Jacques Tati permite un acercamiento a la arquitectura y al urbanismo modernos de posguerra y al contexto socio-económico que favoreció su crecimiento y expansión. Por ello, su obra constituye una herramienta visual muy útil que aún hoy es consultada y mostrada por su claridad y humor y que invita a los ciudadanos –telespectadores- a participar en un ejercicio crítico arquitectónico hasta entonces reservado a los arquitectos. ABSTRACT The film work of French director Jacques Tati could be considered as the perfect reflection of the mid-20th century European post-war building paradigm, a period of time plenty of transformations perfectly echoed by cinema. In particular, Tati’s film work reflects the European post-war citizen’s concerns about the consequences of massive constructions built in their desvastated urban centres, as well as the development of functional cities proposed by the Athens Charter (1931). But, on top of that, an analysis of Jacques Tati’s cinematography allows for an approach to modernity from different perspectives, such as mobility, urban design, new buildings, working spaces in the new tertiary districts, housing -traditional, modern, and experimental-, or furniture design during the post-war period. Embodied by his alter-ego –Monsieur Hulot,- Tati curiously interacts with the new geometric constructions of neutral facades and questions the break with the French building tradition, highlighting the opposition between the nostalgic past and modernity of the 50s and 60s, affected by the fierce consumerism of the new welfare state. The functional, volumetric, aesthetic and even chromatic confrontation between both built worlds –traditional vs modern- invites the viewer to an exercise of meditation and criticism on the European modern architecture of that period. Tati’s film look is particularly focused on two basic concepts: on the one hand, his attention addresses Le Corbusier’s famous mechanistic house which is materialized in the ultra-modern Arpel house (Mon Oncle, 1958) and designed, in turn, when the development of other important experimental dwelling prototypes like Alison and Peter Smithson’s House of the Future or Jean Prouvé´s houses was taking place. It must be highlighted that Jacques Tati’s criticism was not addressed to modern architecture itself but to the wrong use that citizens could make of it. On the other hand, Tati focuses on the Miesian prism through the office buildings that shape the city of Tativille in Playtime (1967). It was a big, modern city built specifically for the film shooting, and based on the almost identical residential and tertiary urban fabrics already active in the main European and American capitals those years. Tativille would work as an autonomous city, having several facilities at its disposal and with the goal of getting integrated and consolidated into the Parisian urban weave. However, its final use was, unfortunately, quite different. In conclusion, an analysis of Jacques Tati’s film production allows for an approach to modern post-war architecture and urbanism, as well as to the socio-economic context that favoured its growth and expansion. As a result of this, Jacques Tati’s film production constitutes a suitable visual tool which, even nowadays, is consulted and shown due to its clarity and humour, and at the same time invites citizens –viewers- to participate in an architectural criticism exercise that, so far, had been reserved to architects.
