El crecimiento, densificación y ordenación de la ciudad difusa en Galicia: desarrollo urbanístico del área urbana de la Ría de Vigo 1990-2010

El área urbana localizada en el contorno de la ría de Vigo se vino comportando hasta finales de los años ochenta del siglo XX como una verdadera "ciudad difusa", entendida la difusión como la forma de urbanización de baja densidad que todavía conserva unas características y una funcionalidad propiamente urbanas, aportadas por la malla tradicional parroquial de caminos y núcleos de población. Esta Tesis demuestra que en el período de veinte años transcurrido entre 1990 y 2010, el área, en la que ya se apreciaban fenómenos de naturaleza metropolitana y policentrismo, experimentó una transformación basada en los factores y formas de urbanización estudiados en otras áreas y ciudades intermedias de similares dimensiones. Para la delimitación del ámbito de estudio se consideraron las diferentes dimensiones y escalas de áreas funcionales utilizadas en distintos estudios y planes territoriales, eligiéndose el que toma como referente principal la Ría de Vigo como soporte de la conurbación polinuclear de su contorno. Para investigar el desarrollo urbanístico operado en el período se estudiaron los factores y formas de urbanización característicos de la urbanización en territorios de baja densidad en esta época, y las variables de densidad es de población y vivienda, primacía y polaridad territorial, ritmos de edificación, planeamiento urbanístico y territorial, actividades económicas, movilidad, desplazamientos residenciatrabajo y vacíos urbanos. Las conclusiones permiten observar como el crecimiento residencial descentralizado, que se ha dado principalmente en el litoral, y la localización periférica de las actividades y dotaciones públicas han introducido elementos de dispersión y fragmentación espacial y social, así como las nuevas y potentes infraestructuras viarias, que han mejorado los desplazamientos a costa de una dependencia abusiva del vehículo privado, y han comenzado a amenazar la sostenibilidad del sistema. La planificación de ordenación territorial a escala metropolitana y el planeamiento urbanístico, que se comenzaron a utilizar con normalidad en esta época, se vislumbran como una oportunidad para reconducir el proceso, integrando los territorios genéricos surgidos entre las nuevas infraestructuras y dotaciones y la malla tradicional, así como los vacíos urbanos susceptibles de compactación, protegiendo aquellos otros vacíos que deben constituir la principal reserva ecológica: Los montes en mano común y la Ría de Vigo. La necesidad de una planificación operativa, sostenible y participativa, que integre la ordenación territorial, la gestión integral de los recursos de la Ría, y articule las diferentes competencias y escalas, la gobernanza , la participación ciudadana y el mercado, se considera la principal conclusión para el futuro. ABSTRACT The urban area located around the Ría de Vigo* used to behave like a “diffused city” until the late 1980s, understanding this difussion as the low-density urbanization that still today exhibits ‘urban’ characteristics and functionality, given by the traditional network of parish paths and town cores. This Thesis shows that during the twenty-year period from 1990 to 2010, this area, which previously showed signals of polycentrism and metropolitan character, started a transformation based on the factors and ways of urbanization studied in other areas and intermediate cities of similar dimensions. In order to demarcate the scope of this study, different dimensions and functional area scales previously used in other studies have been taken into account, choosing the one that takes the Ría de Vigo as the main reference and the basis of the polynuclear conurbation of its surroundings. To research the urban development in this period, factors and ways of urbanization regarding lowdensity territories have been considered, as well as some variables like density of population and housing, territorial primacy and polarity, building rates, territorial planning, economic activities, mobility, home-to-work trips and urban holes. Conclusions allow us to point out how the decentralised residential growing (that occurred mainly on the litoral surface) and the periferic localization of the activities and public facilities, have created elements of “sprawl” and spacial and social fragmentation, which, together with the new and powerfull road infraestructures network (that made the movements easier by means of an abusive dependence on the private vehicle), have started to threaten the sustainability of the system. The planification of the territorial ordinance at metropolitan scale and the urban planning, that in that time started to be established, can be considered as an opportunity to get things back on track, integrating the territories risen up from the new infrastructures and facilities and the traditional network together with the urban holes liable to be compacted, with a special protection of the spaces that must be the main ecological reserve: the communal forests and the Ría de Vigo. The need of a sustainable and participatory operative planification, able to integrate the territory planning, the integral management of resources and the citizen involvement and the market, has to be considered as the main goal for the future.

Sistemas urbanos emergentes: procesos informales de gestión y producción de espacio público

Esta investigación analiza la capacidad del urbanismo de albergar sistemas emergentes de gestión urbana. El objetivo de esta tesis es describir estos procedimientos informales, realizando un exhaustivo recorrido a través de diversas experiencias de alteración del modo de gestión urbana al uso, para dar lugar a una sistematización de estos procesos que siente las bases para plantear nuevas formas de gestión urbana. Es decir, el fin no es tanto hacer una clasificación de las intervenciones más relevantes en materia urbana, sino descubrir su estructura, un orden para el desorden, una taxonomía en esas actuaciones que permita reformular las formas actuales de gestión de lo público. Se ha tratado de dibujar un mapa de oportunidades posibles en torno a la gestión del espacio urbano. A través de los procesos estudiados, esta investigación analiza los éxitos y fracasos obtenidos en los últimos cinco años de gestión alternativa de espacios vacantes, buscando extraer formulas susceptibles de incorporarse al modo actual de hacer ciudad. Este estudio pretende abordar un aspecto parcial, aunque fundamental del urbanismo, dando prioridad a lo público, sin la intención de negar el resto de formas del espacio urbano. Se concentra en los parámetros relativos a la interpretación de lo público: desatiende al conjunto urbano para descifrar ese fragmento. Así, el interés principal de esta tesis se concentra en la producción del espacio público. Al entender este ámbito como no exclusivo del urbanismo, otras actividades como el arte, la filosofía, la antropología o la sociología han aportado aspectos fundamentales dentro de esta investigación. De esta forma se ofrece un acercamiento poliédrico desde puntos de vista interdisciplinares, tratando de descubrir con rigor las posibilidades contrastadas de mejora del espacio urbano producido por los procesos emergentes de gestión informal de lo público. Mediante un metodología creada ex profeso (una estructura definida por tres líneas estratégicas: Gobernanza, Complejidad y Cohesión Social, que se desglosan en seis conceptos clave cada una) esta investigación analiza los aspectos relativos a la producción informal del espacio público de los sistemas emergentes. En relación con la Gobernanza, una parte de esta tesis se dedica al estudio de la informalidad, la transversalidad, la apropiación, la participación, la transparencia y las redes. La Complejidad se ha estudiado en su relación con la diversidad urbana, el uso sostenible del espacio público, la reactivación, la producción de espacio público, la ecología urbana y los procesos creativos. Para Cohesión Social se ha investigado la innovación en equipamientos, los procesos bottom-up, el rizoma, la identidad, los sistemas líquidos y el empoderamiento. Esta máquina para analizar se prueba en tres soportes urbanos: la escena urbana, los edificios-contenedores y los vacíos urbanos. Se han estudiado cinco situaciones urbanas en la ciudad de Madrid, seleccionados por ser las prácticas urbanas más relevantes de los últimos cinco años. Si bien este análisis nace de estos cincos casos, el modelo podría ser útil para otras investigaciones interesadas en los aspectos informales de la gestión urbana. Esta investigación se propone reclamar otras dimensiones más innovadoras que, si bien se escapan a los modos habituales de trabajar del urbanista, se revelan intensamente en los modos actuales de reclamar y producir espacio urbano. Se ha pretendido descubrir el espacio urbano como contenedor situacional del sentido público, potencial multiplicador de efectos funcionales como la gestión, la temporalidad, la participación, la rehabilitación, la multiplicidad de usos, la corrección del compacidad; efectos perceptuales y estéticos en la escena urbana; efectos políticos, de formación, de adquisición de poder; efectos sociales como la generación de nuevas redes, la creación de identidades. Se pretende que esta investigación arroje conclusiones que puedan tener aplicabilidad en la gestión y planificación del espacio público de ciudades y entornos urbanos inmersos a procesos semejantes. ABSTRACT This research examines the ability of urban planning to accommodate emerging urban management systems. The purpose of this thesis is to describe such informal procedures, by carrying out an exhaustive review across the different approaches to urban management, in order to systematize them as the basis for new ways of urban management. The aim is not, that is, to classify relevant urban interventions, but to recognize the intrinsic structure, an order for disorder, a taxonomy in those proceedings that could help reformulating existing forms of public management. The attempt has been to draw a map of possible opportunities around the management of urban space. Through the processes that have been the object of study, this research analyzes the successes and failures over the last five years of alternative management of vacant spaces, seeking to extract formulas that are likely to join the current way of making city. The focus of this urban study is the interpretation of public concepts, considered as key dimensions, not obliterating the other forms of urban space, but trying to make an in-depth analysis of this fragment within the global urban concept. Other activities intrinsically associated to public space generation, such as art, philosophy, anthropology or even sociology, are also contributing to this research. This interdisciplinary approach tries to enrich the research by recognizing the informal elements participating in emergent public management processes. The ex profeso devised methodology is structured by three main strategies: governance, complexity and Social Cohesiveness. Governance considers elements associated to informality, transversal dynamics, appropriation, participation, transparency and networking. Complexity encompasses elements of urban diversity, sustainable usage of public space, reactivation, urban space production, urban ecology and creative processes. Social Cohesiveness includes elements for equipment innovation, bottom-up processes, rhizome, identity, liquid systems and empowerment. This analyzing machine is tested on three urban scenarios: the urban scene, container buildings and empty spaces. Five relevant urban situations in Madrid have been selected, all of them developed in last five years, thus establishing the basis for other experiences of informal urban management. The result of the research, confirms the relevance of additional dimensions to traditional approaches for urban development. The urban space is recognized as a situational container of public sense and a potential multiplier of functional effects such as public management, temporality, participation, rehabilitation, multiplicity of uses, correction of compactness; perceptual and esthetic effects on the urban scene; politic effects, training, empowerment; social effects as generating new networks and identity creation. To sum up, the purpose of this thesis is to share the conclusions obtained by evaluating reference scenarios that could be applied in similar processes for cities and urban environment management and planning.

Urban microclimate and thermal comfort modelling: strategies for urban renovation

The urban microclimate plays an important role in building energy consumption and thermal comfort in outdoor spaces. Nowadays, cities need to increase energy efficiency, reduce pollutant emissions and mitigate the evident lack of sustainability. In light of this, attention has focused on the bioclimatic concepts use in the urban development. However, the speculative unsustainability of the growth model highlights the need to redirect the construction sector towards urban renovation using a bioclimatic approach. The public space plays a key role in improving the quality of today’s cities, especially in terms of providing places for citizens to meet and socialize in adequate thermal conditions. Thermal comfort affects perception of the environment, so microclimate conditions can be decisive for the success or failure of outdoor urban spaces and the activities held in them. For these reasons, the main focus of this work is on the definition of bioclimatic strategies for existing urban spaces, based on morpho-typological components, urban microclimate conditions and comfort requirements for all kinds of citizens. Two case studies were selected in Madrid, in a social housing neighbourhood constructed in the 1970s based on Rational Architecture style. Several renovation scenarios were performed using a computer simulation process based in ENVI-met and diverse microclimate conditions were compared. In addition, thermal comfort evaluation was carried out using the Universal Thermal Climate Index (UTCI) in order to investigate the relationship between microclimate conditions and thermal comfort perception. This paper introduces the microclimate computer simulation process as a valuable support for decision-making for neighbourhood renovation projects in order to provide new and better solutions according to the thermal quality of public spaces and reducing energy consumption by creating and selecting better microclimate areas.

Employee Leadership Development

Abstract \ The business importance of retaining and developing top performing employees is more crucial to business organizations that in the past, yet many organizations are not confident in their ability to staff leadership positions within the next five years. Many companies continue to run without a employee leadership development program. Organizations that shy away from development programs tend to do so because of fear the costs are too high. Organizations that support leadership programs acknowledge that the benefits far outweigh the costs. In this capstone study, the researcher illustrates that employee leadership development programs add value through improved business strategy and employee satisfaction, and as a result, represent a worthy investment.

La valorización de los espacios naturales como pretexto para el desarrollo urbanístico en el sudeste de España

El objetivo de este trabajo es exponer algunas de las claves que explican los impactos ambientales de la actividad turística en la costa mediterránea española. Se analiza la instrumentalización del turismo por parte de la industria de la construcción a partir de la implementación de una serie de pautas de actuación puestas al servicio de un principio básico: el sometimiento de la conservación de los espacios naturales más frágiles y valorados a los intereses del capitalismo inmobiliario. Este argumento se ilustra mediante la exposición, desde una perspectiva histórica, geográfica y sociológica, de las dinámicas presentes en Calpe y Torrevieja: dos municipios de la Provincia de Alicante, situada en la Comunidad Valenciana, en el sudeste de España.

Fault development and interaction in distributed strike-slip shear zones: an experimental approach

Analogue model experiments using both brittle and viscous materials were performed to investigate the development and interaction of strike-slip faults in zones of distributed shear deformation. At low strain, bulk dextral shear deformation of an initial rectangular model is dominantly accommodated by left-stepping, en echelon strike-slip faults (Riedel shears, R) that form in response to the regional (bulk) stress field. Push-up zones form in the area of interaction between adjacent left-stepping Riedel shears. In cross sections, faults bounding push-up zones have an arcuate shape or merge at depth. Adjacent left-stepping R shears merge by sideways propagation or link by short synthetic shears that strike subparallel to the bulk shear direction. Coalescence of en echelon R shears results in major, through-going faults zones (master faults). Several parallel master faults develop due to the distributed nature of deformation. Spacing between master faults is related to the thickness of the brittle layers overlying the basal viscous layer. Master faults control to a large extent the subsequent fault pattern. With increasing strain, relatively short antithetic and synthetic faults develop mostly between old, but still active master faults. The orientation and evolution of the new faults indicate local modifications of the stress field. In experiments lacking lateral borders, closely spaced parallel antithetic faults (cross faults) define blocks that undergo clockwise rotation about a vertical axis with continuing deformation. Fault development and fault interaction at different stages of shear strain in our models show similarities with natural examples that have undergone distributed shear.
