The impossible project of public space

Manuel de Solà-Morales
...

... A deliberation such as this is confronted with a terminological problem: the semantic debasement of the term “public space”, which is indiscriminately used for any exercise in land-filling, transforming or prettifying vacant land. All too often, the category of “public space” is used without taking into account the requirement of real urban quality that the term entails. This urbanity is the quality of significant places of collective and political content in their very material form. “Material urbanity”, the ability of urban material to express civic, aesthetic, functional and social meanings, is a basic concept when it comes to defining public space and, hence, intrinsic to the aims of this Prize.

Otherwise, a cramming of forms and planimetric geometries, the unease of frustrated architectural projects at zero elevation, or an arbitrary compositional interplay of surfaces can come to occupy public terrains with apparently infinite freedom. Mannerism is conspicuous, while the vocabulary of alignments, lamp posts, pavements, high ground and low ground, pergolas, ramps and green patches burgeons ad nauseum.

The pervasive magnitude of such practices, the growing number of projects (whether in squares and streets, parks, service installations and facilities or other places) would seem to make it necessary to re-propose a strict notion of public space as a material condition (locus) of political space.

Civic space is very difficult. Some projects merely reform outmoded spaces which are, on occasion, of great urban significance, to give them innovative or surprising, subjectively affirmative forms. Others confront new spheres of urban growth in order to procure therein some expression of public dignity. Still others understand the site as an available empty area, making the most of the occasion to invent new artifices, installations of a new urban symbology.

Yet, whatever the case and for all these limitations, there appears the indisputable fact of the high average quality attained in different municipalities by the methodological effort and technological training of the professionals concerned, the growing attention of public authorities and the great degree of satisfaction among the citizens with these projects. This is an extraordinary process of the invention, over twenty years, of a socially and culturally recognised quasi-discipline.

Speaking of public space can be a rhetorical convention that covers up the confusion that stands out over and above the values pertaining to the city as a political place, place of subjective intervention, place of the “polis”. If we accept the hypothesis (advanced since 1992) that it is the collective condition that defines urbanity and that, therefore, the collectivisation of spaces and homes, people and institutions, economic movements and activities, is the supreme effect entailed by urbanity, then we would have to think that all the places of the city, public and private, individual or corporative, are partly public spaces since they share the way in which they are appropriate for the citizens. The buildings and streets of a city, the squares and monuments, factories and schools are, in good part, felt as belonging to the residents and, to the extent that they are affected by their functional and aesthetic characteristics, they are the object of citizens’ opinions and claims. In contrast, a rural cultivation or construction is free of this collective dependence: it is an autonomous fact, isolated in its internal logic and does not form part of any formal integrated collective but, rather, belongs to the collective that is simply referred to in neighbourhood relations (or the superstructural notion of “landscape” as an environmental value, without express political content).

Hence, if all urban space is more or less public (and all public space is more or less of or for private interests), what would be the specificity of what we conventionally call “public spaces”? What would a Prize (European or otherwise) for “public space” projects be about? Can we determine which projects count and which ones don’t as such spaces? And once they are singled out, should the projects be evaluated for the intensity in which they are “public” (the more “public” a project, the higher the grade), or according to how good the spaces are (more attractive, more functional, more impressive), or for the degree to which they incorporate certain critical questions that the contemporary city has not yet managed to collectivise (traffic, segregation, largeness of scale, sustainability)?

These are questions that are interesting not only for jury members since they also rebound on the definition itself, questioning the specific nature of public space and maximally so when the deliberation is not so much about real public spaces but about “projects” of would-be real spaces. Does this, then, belong to the jurisdiction of inventiveness, design or innovation? Is it formal surprise or thematic modernity that has greater value? Is it difficulty overcome or is it effectiveness of transformation?

To go still further, what is it that constitutes public space as real experience? Over and above sociological, political and functional reflections, what has just made public space recognisable is a material fact. A fact where aesthetics is frequently distorted and distorting, yet where expression and communication pass through a particular material configuration.

The great amount of work carried out in recent years on public spaces, the mushrooming of assignments and projects, the tireless energy of architects and engineers, designers and artists, landscapers and botanists – all of them set on enhancing scraps of non-built-up urban land – the ideological discussion and the intellectual strivings towards bestowing a theoretical status and/or disciplinary entity to these matters, have extraordinarily enriched professional practices and heightened the attention of public administrators. Interest in public space seems to be self-justifying. And this, if exaggerated, can lead to unintended results. Not only words can lose their sense but the works themselves can too. The number of interventions, the arbitrariness of the projects, the frequency in space and time, the copying of cliché models and figures, the fashions and squandering of economic resources can pervert the original nature of public space as collective space par excellence: space that is not appropriated for any fad, or author or actor, or any currently prominent politician, a place that is available for open interpretation and an intersection of interests.

Public space or show room? The very valuable collection of projects that the CCCB has been putting together over the years, as with the European Archive for Urban Public Space, can simultaneously give rise to contradictory feelings of admiration and misgiving. This is a catalogue of excellence that permits one to discover what terms – old and new – have captured the attention of administrators and project designers, and what examples have been giving rise to prototypes and sequences. It is an incontrovertible demonstration of the enormous surge in attention to matters pertaining to the city’s public affairs and the public cost-effectiveness of giving them material form in different corners of the city or in available bits of land. Again, however, the sight of so many, many projects all together also lays bare the repetition of a lot of gratuitous gesturing and a great deal of gymnastics in forms striving for originality and surprise, as if public land were a blank page for the personal pleasure of the project designer. Undulations, ruptures, continuities and rows, screens and splodges, are combined – always out of the blue – as pieces of a closed and self-referencing composition.

It would appear that the proliferation of these sorts of jobs is tending to bring about a new form of autonomous professional practice which sees the precinct where the work is to be done as a free range in which zero-elevation architecture might be invented, an unconstrained exercise in which – relatively – low-cost forms and images can be explored in freedom that could not exist in construction that is constantly submitted to the much stricter requirements of the programme, costs, functions, structure and client.

In dealing with public space, one finds that it may be the leading issue of urban form or it can be mere anecdote. It depends on the scale (not the measure) in which we look at it. Public space as a combined structure of different streets and squares is the essence, the substance of coexistence, interaction and the redundancy that shared life brings. Designing the structure of spaces for the mobility, leisure and representation that link spaces of activity is what traditional urban planning is all about. In a certain sense, thinking that the quality and form of shared spaces is prior to and more important than pinpointing particular functions is now a methodological option that is rarely taken.

Yet it is not the scale of the urban whole that we usually have in mind when we speak of “public spaces”. To the extent that we keep circumscribing the idea of public space to a precise, delimited place, we are losing our perspective on it as a basic urban structure and giving priority instead to the singularity – morphological or environmental – of each site as an autonomous urban lot, as an occasion for independent formalisation. Hence, the many commissions for designing large or small public spaces viewed as specific objects turn into drawings of a closed lot, self-referencing designs frequently with an arbitrary perimeter. The site is thus converted into a platform of experimentation, a show room in which to play with paving and lamp posts, slopes and corners, with the utmost independence.

Again, the extension of this plethora of project-designing activity covers a considerable range of countries and cities. The interest in breathing modernity into public land is expressed in the demand everywhere and each project, each civic example, can be understood, from a certain standpoint, as part of an extensive process that, over the past twenty years, is bringing about a wide-ranging renovation of the whole urban epidermis of Europe. As in the periodical cellular replacement of human skin, the connective surface of European cities, its interstitial tissue of roads and paths, of gardens and squares, of what is most common or substantial and also most structural and most necessary of urban space, is being replaced, extended and manifested. What, thanks to its basic condition, was once taken as being obvious – paving, offering stable physical support for the contact of urban things and the mobility of citizens – is now an optional and symbolic matter, a question of design.

The construction of public land, hitherto the immediate result of technical needs and means, is nowadays the object of alternative offers and questionable taste. An aerial view of the map of Europe with coloured lights illuminating the progressive work over the paved surface of Europe would impress us with its extension and variety. And it is difficult to overstate the importance of this vision. This is a historic step in the concept of the city, as space held in common, in the idea of public space as a material place.

Perhaps it will only be after this careful, overall urban planning momentum, this process of expansive culturalisation of the European ground-plan, that the merits of the different projects might be judged, for what they manage to establish as a general idea of urban space and not only as attractive planimetric gestuality.

After all, at bottom, almost all the projects are works of repaving, more or less initiatives of replacing the urban skin, a surface that is in itself a deep structure. Paving, with ground as support and link, has an extensive and not a singular condition and proclaims the central role of interdependence. Public spaces will be just that when they construct the combined system of urban space and not merely a closed work. When they are defining elements of a model of the city without perimeters, rather than zero elevation architecture. When they become the representation of mobility, coexistence and conflict rather than stylised, neatly resolved landscape.

Scrutiny of the projects present in the European Archive for Urban Public Space suggested to me that they should be sorted according to their stance as proposals, their methodological pretensions. It is not easy, I believe, to produce the usual typological, thematic or scale-oriented classifications. The precise intention behind the project, which is not easy to divine either, can help us, however, to advance in critical knowledge of public space practice. Four types may be distinguished here:

1. Tidying-up projects: there are many projects (the greater part) that re-order spaces on top of themselves, making them more useful, more attractive and more novel. They respond to political intentions of visible investment, which are specific to more difficult or more representative spaces. They set out to bring them up to date and spruce them up.

Rarely do these projects convey any content other than a good makeup job.

The evaluation to be made in this case is primarily functional.

2. Projects that expand the previous sphere of public space and that, even while sticking to known typological guidelines, set about designing new areas, different in scale and location, either because of topographical difficulties or thematic complexity. This is basic urban planning activity.

These works have a technical value.

3. Projects that collectivise. These projects, the most incisive, accept the strategic goal of creating public space with private ingredients, on the basis of an understanding of collective space (public+private) as a defining substance of what is urban. Explicitly or otherwise, such projects take the view that urbanising means collectivising, and they may have a lot or a little in terms of form, but they do not shape. Rather, they are actions of mental strategy.

In their intimate sense, they have a political value.

4. Projects that invent. These are the few initiatives that are born of an ill-defined occasion, without any specific programme, without purpose and without clear limits. They propose uncommon images on the basis of inventing a type of public space for which, precisely, there is no type. It is the invention of form and programme at the same time and means accepting the risk – of error, or failure – as a premise of planning.

The value here is artistic.

However, it is also necessary to stipulate that not all public space entails urban quality just because it has been successfully organised. A project can value the characteristics of the place and can express landscaping or utilitarian qualities without managing to give material form to any notion of urbanity. The rehabilitation of the Gavà beaches, for example, has produced an excellent, sensitive and intelligent public leisure space but it does not express the urban quality that, in contrast, is to be found in the Mar Bella shoreline project, which is perhaps less attractive. The aims and contact with urban complexity are so different in these two cases that, whatever their intrinsic merits, we cannot consider the former as urban space while the latter can come under that heading. We might say much the same if we compare the Plaça Europa and the Plaça Lesseps. The infrastructural density and formalist vocation of the former cannot contribute urban quality to the site because of the devastating effect of the design materials, the measurements, forms and elements while, in contrast, the chaotic solutions in the Plaça Lesseps are surpassed as a whole by the active and heterogeneous centrality of the place and the permissive tolerance of all the lateral manifestations (of facades, movements, angles of vision and uneven surfaces) that have appeared.

Neither can the ring routes, as intrinsically circulatory spaces, be regarded as urban space. The evident absence of any relationship with the adjoining city and the highly homogeneous character of their support materials, reduce any urban quality to mere mechanical channels. This is the case despite the “urbanising” efforts that have so meritoriously been attempted. In fact, this is an act of oversimplifying urban complexity, reducing it to monographic landscape. The Metro, on the other hand, is usually a “hyper-urban” space: the parts we see and understand (entrances and stations) are made up of people, signs, connections and train carriages, all of them different materials that suggest a high degree of urban quality. What we do not see – the tunnels – are black and make of the mechanical part of transport an absent, irrelevant fact.

All public space projects are precisely that in the sense of public conception and administration. But not all of them constitute spaces of urbanity in the civic, political and figurative senses that go with the good city. Some are spaces for the public and others are urban public spaces. Public space combines “urban things”, physical materials that are able to make perceptible an idea of the city. Hegel said that beauty is the perceptible expression of an idea. And this is the grandeur and difficulty of public spaces. Ground and mud, cobblestones and slabs, asphalt and concrete, wood and leaves on the trees shift here from being generic to components for making urban quality a material thing. Walls, land, lamp posts, doorways, ramps, vehicles, corners and crannies establish the sensations of the mind that bring people into relation.

The city, macle of conflict and solidarity, stability and dynamism, connection and distance, appears in the material condition of public space. Over and above sociological, political and functional considerations, public space imposes itself as a material fact, a substratum joining matter and idea, trying to ensure that it turns out to be beautiful. Walter Benjamin, Richard Sennett, Paul Virilio and Fredric Jameson have given much thought to all this.

Physical urban quality is in the measure, the proper understanding of the limits of a space. As soon as we define it, we segregate it. Good public space has no limits, or the ones it has are undefined, multiple, oscillating. As a relative place, its references to the urban whole are more important than its own identity and yet this is enhanced thanks to them. Watch those perimeters! They are both main theme and baptism of fire of urban quality.

The urban nature of urban materials also lies in the sense of touch. Even more than in sight, perhaps. In public space, personal experience, the route and comfort are fundamental. Walking on a hard or soft surface, stone or sand, on corrugated or slippery ground brings about very different sorts of contact between body and brain. The idea is transmitted through the different sensations of the material used. And the proximity of the hands to railings, walls and benches makes us experience, more than in any other sense, the character of space. If by means of sight we understand shaping, size and setting, by touch we experience identity, treatment and character.

In the contemporary city, we can no longer see public spaces with reference to a notion of urban, functional or semantic structure, as we did in the years of structuralism but, like the Greeks, we need to read civilised space as a topological, tactical order. We must go beyond landscaping decorativeness and recognise the warp and weft of materials, which is what the proto-modern Gottfried Semper studied and called for.

In the thinking of the 1970s and the following years, little was said about public space except, perhaps, the notion of centrality as the symbolic locus of life in common. Henri Lefebvre, who showed great foresight at the time, criticised the city of the Modern Movement, saying that “la ville est du trans-fonctionnel durable”, already seeking rupture in the paradigm of structure as the idea of a city. Today, perhaps, leaving aside all the many tricky metaphors used as an excuse for a project, one must seek instead an idea (of public space, of a bit of city, of urban quality, of a political place) in the absence, precisely, of symbolic images, or picturesque novelty (all, alas, globalised) and a possibility of civic identity in the dissolution of the individual place in the collective milieu, in pure citizenship.

The individual is attenuated when public space is offered as a readied room. Napoleon, when he reached the Piazza San Marco on invading Venice, said that it is “the most beautiful salon in Europe”, seeing in it a space to be used in keeping with norms and customs; the exact opposite of Barcelona residents freely enjoying Mar Bella. Desacralised public space is the condition for the city’s existence and without public space the only things left are the rural setting and castles.

A emergência da dimensão existencial nas cidades - Uma proposta a partir do Centro Histórico de Évora

Autora:
Susana Mourão
Infohabitar, Ano IX, n.º 446

Resumo

O Centro Histórico de Évora é Património Mundial desde 1986, pelo seu conjunto de valor patrimonial que é um elemento primordial de estruturação, caracterização, e identificação da cidade de Évora. Para a Salvaguarda e Valorização Patrimonial do Centro Histórico de Évora foi desenvolvida uma política de preservação do seu carácter patrimonial e dos elementos que constituem a sua imagem adaptando-os à vida contemporânea, e todas as intervenções são condicionadas ao seu valor patrimonial e ao seu espaço envolvente. Neste sentido, com a Classificação de Património Mundial e a sua respectiva política de Salvaguarda e Valorização Patrimonial, podemos afirmar, que o Centro Histórico de Évora de um lugar de vocação Patrimonial.

Mas, o carácter do Centro Histórico de Évora vai além da sua “imagem” patrimonial ou dos elementos patrimoniais que o constituem, ele é um lugar do dia-a-dia da vida humana, sendo o seu espaço preenchido pelo sentido humano de habitar. Por isso, o carácter deste lugar é significativo e não apenas uma imagem para quem o habita. Assim, sendo o Centro Histórico de Évora um lugar habitado, a sua política de Salvaguarda e Valorização Patrimonial está distante de quem o habita, sendo emergente a sua dimensão existencial.
...

Conclusão

Após a análise, da política de Salvaguarda e Valorização do Centro Histórico de Évora, e a sua implementação através do rigor de um projecto de reabilitação de um edifício, condicionado às questões patrimoniais, podemos afirmar, que esta competência de reabilitação apoia-se num planeamento prospectivo que parte do seu património físico e projecta a preservação da sua imagem para o futuro, e esquece a sua dimensão existencial, isto é, o modo como se vive e como se sente no Centro Histórico de Évora.

Assim, é necessário que esta política de salvaguarda e valorização patrimonial ultrapasse este impasse de “culto patrimonial” que está distante do fenómeno do dia a dia da vida humana: o Centro Histórico de Évora é um lugar habitado.

Enquanto lugar habitado, o Centro Histórico de Évora não é um espaço “vazio” e com um carácter meramente visual, mas sim um espaço preenchido pelo sentido humano e revela um carácter significativo por quem o habita. Para tentar sair deste “culto”, temos que tentar olhar o corpo patrimonial do Centro Histórico de Évora como equivalente simbólico ao corpo humano, e reabilitar este corpo patrimonial é sinónimo de reabilitar o corpo de quem o habita. Assim, a partir desta experiência no Centro Histórico de Évora propõe-se a emergência da dimensão existencial nas cidades, porque “as cidades actuais vivem em função de um passado, presente e futuro através do seu planeamento prospectivo. Este planeamento prospectivo é fruto de uma cultura tecnológica, que valoriza o tempo futuro e operatório das mudanças nas cidades, e esquece o tempo existencial de como as cidades vivem e sentem o seu tempo.”

Post-Crash City: Environments & Ecologies

The Post-Crash City
A high-profile conference series, spanning 2012 through 2013, which covers the contemporary crisis and changes in urban systems.

The global financial crisis has provoked re-analysis of the limits and social harms associated with our economic systems and its relationship to urban life. The move to conditions of an economic reverse, a crash of arguably unprecedented scale, has been met with wavering commitments to expand and draw-back from the public financing of both private and state institutions. Proposals in many western and other countries globally for massive public cuts raise the prospect of economic stagnation and indeed social pain generated by the withdrawal of state supports for the most marginal members of society. This context presents important challenges to critical social analysis.

What will this crisis, and its unwinding in different social spheres and spatial contexts, mean for cities globally and nationally? How can we effectively monitor, critique and add to public debates, community action and institutional ways of thinking that might encourage more genuinely progressive and incisive diagnoses of the collapse of urban conditions? This conference series has been created to address these issues by creating a space for dialogue and the dis- semination of research and ideas around how urban life has and will continue to be transformed by this most recent and dramatic set of transformations in economic systems globally.

Post-Crash City: Environments & Ecologies

Quando:
Março de 2012 a julho de 2013

University of York’s new Heslington East Campus

Quem organiza:
Centre for Urban Research at York (CURB)

The argument that environmental issues are deprioritised by policymakers and the public during times of economic decline has once again emerged. There is evidence to support these claims, some argue that urban green spaces are being neglected as a result of budget cuts, equally, others highlight challenges to urban regeneration, with funding sources more limited and projects harder to negotiate, especially with less desirable spaces such as polluted brownfield sites. Ironically some argue that environmental problems may have actually lessened during the recession, for example, Castellanos and Boersma (2012) attribute a 20 per cent drop in NO2 levels in 2010 in Europe at least in part to the global recession. However, despite the cuts, in the UK some environmental agendas clearly remain in place and are becoming a more standard part of policy rhetoric, especially those relating to low carbon initiatives. It is also becoming increasingly more unusual to find low carbon strategies that do not take into consideration (at least on the surface) broader social concerns such as poverty and social inclusion.

These issues raise a number of questions: how are urban environments changing as a result of this altering terrain? Are new networks forming in order to continue environmental or social goals that were previously supported through the public purse? Are social and environmental goals being balanced differently since the recession?

Methods for Multilevel Analysis and Visualisation of Geographical Networks

Céline Rozenblat (Editor),
Guy Melancon (Editor)

This leading-edge study focuses on the latest techniques in analysing and representing the complex, multi-layered data now available to geographers studying urban zones and their populations. The volume tracks the successful results of the SPANGEO Project, which was set up in 2005 to standardize, and share, the syncretic, multinational mapping techniques already developed by geographers and computer scientists. SPANGEO sought new and responsive ways of visualising urban geographical and social data that reflected the fine-grained detail of the inputs. It allowed for visual representation of the large and complex networks and flows which are such an integral feature of the dynamism of urban geography. SPANGEO developed through the ‘visual analytics loop’ in which geographers collaborated with computer scientists by feeding data into the design of visualisations that in turn spawned the urge to incorporate more varied data into the visualisation. This volume covers all the relevant aspects, from conceptual principles to the tools of network analysis and the actual results flowing from their deployment. Detailed case studies set out in this volume include spatial multi-level analyses of flows in airports and sea ports, as well as the fascinating scientific networks in European cities. The volume shows how the primary concern of geography—the interaction of society with physical space—has been revivified by the complexities of new cartographical and statistical methodologies, which allow for highly detailed mapping and far more powerful computer analysis of spatial relationships.

Preface

During the last decade, research on networks has developed rapidly in most scientific disciplines. Several factors explain this sudden interest, which has led to an exponential growth in the dedicated literature from the natural to the social sciences. Technical advancements have certainly facilitated this exceptional development. Although graph theory and analytic concepts about graph structure and dynamics did exist before the 1960s (Berge, 1958), the processing of large connectivity matrices remained limited for a long time by the insufficient power of computers. On the empirical side, relational data were scarce or were very expensive to construct. Indeed, the significant increase in the speed of computing that has occurred recently as well as the proliferation of new types of empirical relational data that have been made viable because of the Internet have boosted the creation of powerful tools for network analysis. In parallel, many important modern societal trends have emphasized the need for developing adapted concepts and theories to help understanding these trends, which include the globalization processes that mainly operate through networking relationships; the trend toward decentralized management, the trend toward more participative or cooperative organization than the classical hierarchies; and the unfolding of individual connections through increasing mobility and educational level of population accompanied by various communication tools, to the extent that social networks are now considered to be a major source of “big data”.
Among all of the social sciences, geography is well advanced in analyzing and modeling networks. Physical networks, such as the hydrographic, transportation or infrastructure networks, are part of the structuring of the geographical space. The descriptions of these networks were formalized decades ago, for instance, by models such as Horton’s laws or accessibility and connectivity indices (Garrison, Berry, Marble, Nystuen, & Morrill, 1959). Thereafter, exchanges of goods, people and information between places were considered to be a possible fundamental explanation of geographical diversity leading to a conception of geography as a science of “spatial interaction” (Ullmann, 1954). Theoretical and operational models of spatial interaction were already well established in the 1970s (Wilson, 1970). The gravity model representing trip distribution was even considered to be “the first law of geography” (Tobler, 1970).
However, until recently, there were few methods for fully exploiting the vision of geographical space as a relational space, defined according to the many possible configurations by the interactions between georeferenced entities. Introducing that vision is the most salient aspect of this book. This book develops an integrated set of theoretical interpretations and adapted methods for exploring a variety of networks. These original and reproducible methods were elaborate, due to a long and involved interdisciplinary collaboration, between a laboratory of data processing and a network of geography researchers. A geographer, Céline Rozenblat, and a computer scientist, Guy Melançon, together developed a theoretical conception of geographical networks produced by dynamic processes in complex systems. They also conceived and adapted methods and software for visualizing the specific configurations of relational spaces that are operating at different scales of analysis within these networks. These scholars both succeeded at stimulating interest and animating a group of scientists from Canada, France and Switzerland, who worked together since 2005 when the SPANGEO program was initiated.
A major achievement of this project is the continuous development of the TULIP software, which is dedicated to the visualization of large networks according to the measurements of centralities and proximities in a variety of ways. As the networks analyzed by the geographers connect located objects, they are often rather strongly structured by the constraints that the distance exerts on the practices of communication or displacement. Explaining their structure implies combining the identification of topological organization (for example, small world configuration) and measurement of metrics on weighted interaction flows (representing, for instance, group cohesion). Moreover, as urban centers are the places where social interaction organizes in networks on many scales, from daily commuting patterns to worldwide air transportation system, there was a specific need for integrating within the measurement procedure—the hierarchical structure of urban systems that guides the many patterns of socio-spatial interaction. In addition to the usual methods for detecting communities within the network through various clustering methods, the TULIP software allows for a multi-level analysis of connections that are considered both at the intra-urban and the inter-urban level. This component is especially useful, for instance, in applications to urban economy when exploring the diversity of linkages among firms or among scientific researchers inside—as well as between—cities. This type of tool opens the door to a more specific appraisal of the so-called agglomeration economies, which may in fact represent “network effects”.
Thanks to the efforts of the SPANGEO interdisciplinary group, we warmly welcome the novel feasibility of approaching the geographical space as a relational space. In the contemporary expansion of methods for network analysis, too many workers are satisfied with implementing standard algorithms or measurements on data files that are collected quickly, which yields results that are trivial or are difficult to interpret. This type of data appraisal was not followed in this work. Instead, this work proposes a method that fully integrates geographical theory with topological analysis, providing relevant measurements of centralities and proximities inside a method of visualization. Historically, geographers have used the integrative power of eyesight to envision the peculiarities of landscapes and places, constructing maps for encoding the accumulated knowledge from this process. It is now time to integrate sophisticated visualization tools in the cognitive elaboration of models and theories of spatial interaction that are occurring within the complex geographical systems and, in the process, continuously reshaping them.

Premio Europeo del Espacio Público Urbano


El Premio Europeo del Espacio Público Urbano es una iniciativa del Centro de Cultura Contemporánea de Barcelona (CCCB) que, a raíz de su exposición “La Reconquista de Europa” (1999), decidió ser testigo del proceso de rehabilitación de los espacios públicos que tiene lugar en muchas ciudades europeas.
El Premio nació con el fin de reconocer y promover el carácter público de los espacios urbanos así como su capacidad de cohesión social. Asumiendo las ambigüedades inherentes a la noción de espacio público, el Premio es el único en Europa que reconoce y promueve un espacio a la vez público (abierto y de acceso universal) y urbano. El Premio se distingue así de otras iniciativas centradas en la figura del arquitecto y de los premios consagrados al paisaje, para poner de relieve el carácter relacional y cívico del espacio típicamente urbano.

Con el tiempo, varias instituciones europeas se han unido al proyecto, que actualmente ya es co-organizado por The Architecture Foundation (Londres), el Architekturzentrum Wien (Viena), la Cité de l’Architecture et du Patrimoine (París), el Nederlands Architectuurinstituut (Rotterdam) el Museum of Finnish Architecture (Helsinki) y el Deutsches Architekturmuseum (Frankfurt).  A lo largo de las cinco ediciones anteriores, pues, el Premio se ha consolidado institucionalmente, factor que ha permitido también ampliar su alcance geográfico. En efecto, en la edición del 2010, el Premio recibió 303 proyectos de 32 países europeos (frente a los 81 de 14 países en el 2000), constituyéndose así en una ventana de la transformación de los espacios públicos en Europa y en un termómetro de las principales preocupaciones de las ciudades europeas.

El Premio tiene muchas singularidades. La primera es que se concede a la vez al arquitecto y a la administración pública (Ayuntamiento o representante político) que ha tomado la decisión política de realizar la intervención y a menudo también garantiza su financiación. El carácter honorífico del Premio es su segunda singularidad. La tercera es que el Premio no apunta, o, en todo caso no únicamente ni de manera prioritaria, a las grandes actuaciones urbanísticas, sino a las intervenciones de cirugía urbana –grandes o pequeñas-- que pretenden ante todo mejorar las condiciones de vida de los ciudadanos. La prioridad se asigna pues a la arquitectura con vocación social antes que a las intervenciones con un acento estético o espectacular. La cuarta singularidad del Premio es su vocación claramente europea. En efecto, aunque preserva las particularidades locales, el Premio procura exaltar los rasgos comunes de las intervenciones urbanísticas a lo largo de la geografía europea, intentando así promover y difundir una cierta identidad europea en el ámbito de la arquitectura.

Una selección de los proyectos presentados históricamente al Premio se conservan en el Archivo Europeo del Espacio Público Urbano y se complementan con la Biblioteca Urbana, que publica los textos de les conferencias de temática urbana más significativas que se han pronunciado en el CCCB. El Premio se inscribe en el marco de la reflexión multidisciplinar y permanente del CCCB sobre ciudad y espacio público.

Reabilitação Urbana, tem que ser e que seja agora

CRÓNICA
blogue do Mestrado em Planeamento Regional e Urbano da Universidade de Aveiro
Segunda-feira, 17.06.13

artigo de opinião de Jorge Carvalho, docente do DCSPT

Quando confrontado com uma qualquer perspetiva coletiva de desenvolvimento, o crescimento edificatório ocorrido nos últimos 30 anos em Portugal revela-se absurdo.
O número de alojamentos cresceu 2,5 milhões, enquanto o aumento do número de famílias pouco ultrapassou 1 milhão. Investiu-se quase apenas em edifícios novos, enquanto na média europeia o investimento em reabilitação e renovação representou 60%.
Desbaratou-se uma enorme fatia das nossas poupanças em bens que geraram emprego, mas não riqueza, e que agora se revelam excessivos e até, em parte, inúteis. Entretanto, deixou-se ao abandono património localizado em áreas bem servidas por infraestruturas e equipamentos, numa exibição de enorme desperdício, prejudicando fortemente a qualidade do ambiente urbano de vizinhança.
Tudo isto demonstra a falta de racionalidade do mercado imobiliário, mas também a falta de eficácia da Administração Pública, a quem cabe o dever de ordenamento do território. Este caminho não poderia continuar indefinidamente. Já quase todos vão compreendendo que o futuro tem que passar pela reabilitação urbana.
A atual crise económica e financeira põe essa necessidade ainda mais em evidência mas, por outro lado, cria dificuldades à sua concretização. Hoje os recursos são muito escassos, pelo que a reabilitação só irá acontecer se forem desenvolvidas políticas públicas que mobilizem e articulem capitais privados e públicos, na lógica do “muitos poucos fazem muito”. Para tal há que adotar políticas convergentes e complementares, de âmbitos nacional e local, mobilizando um leque de instrumentos de incentivo e de pressão sobre proprietários, promotores e utilizadores. Não basta “pregar” a reabilitação, é necessário que a reabilitação se torne de facto vantajosa para todos, ao contrário do que aconteceu nas últimas décadas.
Esperamos ter a oportunidade de divulgar, em breve, uma proposta concreta neste sentido, que elaborámos para a Avenida Lourenço Peixinho e que poderá ser estendida a toda a Área Central de Aveiro. É conhecido, tendo sido amplamente discutido, o projeto base que elaborámos para o espaço público da Avenida, visando sobretudo o reforço da sua função pedonal. Em seu complemento, apresentámos recentemente uma proposta com vista à reabilitação dos edifícios, que passa pela delimitação de uma “Área de Reabilitação Urbana” e pela consequente utilização de todos os instrumentos para tal previstos no quadro legalem vigor. Dedestacar, entre as propostas apresentadas, uma fiscalidade sobre o imobiliário que incentive a reabilitação e penalize a degradação e o abandono e a adoção de mecanismos perequativos (edifícios que possam crescer a compensar e subsidiar a reabilitação dos que deverão ser conservados). Esperamos, então, voltar a este assunto num futuro próximo, no quadro da discussão púbica de uma proposta de intervenção municipal de Reabilitação Urbana, neste caso com incidência em Aveiro, mas cuja filosofia pode ser aplicada em muitos outros locais.

"Volta a Portugal” - Álvaro Domingues - Quintas de Leitura

Quando:
20 de Junho

Onde:
Porto - Teatro do Campo Alegre

Este ano, mais cedo do que é habitual, chega até nós a “Volta a Portugal”, pela mão das “Quintas de Leitura”, ciclo poético organizado pelo Teatro do Campo Alegre/Câmara Municipal do Porto. O espetáculo, que junta no mesmo palco o geógrafo Álvaro Domingues e o poeta Rui Lage, realiza-se no dia 20 de Junho, às 22h00, no Auditório do Teatro do Campo Alegre.

Álvaro Domingues faz a sua quinta aparição neste ciclo poético e desafia-nos com mais uma das suas inclassificáveis conferências esquisitas, desta feita, intitulada “Volta a Portugal”. Explica assim o teor da sua intervenção:

“Entre lírios, campos e toxicidade, Volta a Portugal será um manual para viajar pelos lugares comuns do chão da pátria lusa. Agora que a Volta a Portugal em Bicicleta já não tem o mesmo poder de revisitar e produzir as mitologias heroicas que culminavam na subida à Serra da Estrela, e que o Guia de Portugal saltou para o GPS ou para a superabundância da propaganda turística que povoa a internet…, vamos percorrer outros caminhos e encruzilhadas em busca de um Portugal entalado entre a crise, a Europa, a globalização, o passado mítico e o presente contingente.”

NOTA EXPLICATIVA
Esse trabalho é a primeira parte da pesquisa desenvolvida sobre a cidade de Itá Santa Catarina/ Brasil e traz inicialmente, indicadores socioeconômicos como a mudança de padrão salarial e de idade dos moradores, bem como a transformação radical da sua base socioeconômica ocorrida após implantação da Hidroelétrica de Itá e o deslocamento da cidade inteira para um sítio mais alto fora da área alagada onde ficava a cidade original.
Nessa primeira parte também será apresentado a base teórica um dos indicadores espaciais a serem utilizados para a análise da estrutura urbana nos três marcos históricos avaliados, sendo essa a teoria de redes complexas.
A teoria sobre redes complexas será aplicada nos casos reais na segunda parte do artigo que trata mais objetivamente das propriedades espaciais relacionadas ao caso. Por isso será apresentados à evolução do comportamento da forma urbana através da Geometria Fractal e Estatística Espacial.

RESUMO
O desenvolvimento da cidade de Itá constitui um processo inusitado, pois 16 mil pessoas foram deslocadas de onde viviam e relocadas em outra área definida por um projeto urbano desenvolvido pela equipe da Hidroelétrica de Itá que teve sua construção iniciada em 1967 e gerou um lago artificial inundando a cidade original em 2000.
Essa pesquisa foca a antiga cidade Itá, o projeto implementado em 1989 e sua configuração urbana atual. Indicadores já existentes e testados em diversos casos reais serão utilizados para obter um quadro seguro dos dados levantados e permitirão comparar as três fases do sistema urbano elencadas para o estudo. Além da questão da evolução da configuração espacial e forma urbana, também serão estudados quais os impactos socioeconômicos causados pela implementação da hidrelétrica sobre a população da cidade de Itá e Região, e o desenvolvimento urbano posterior.

4. COMENTÁRIOS FINAIS
Um processo urbano dinâmico pode ser descrito como o crescimento do número de firmas e residências localizadas em uma cidade. Em qualquer período as firmas localizadas em uma cidade são “seguidas” por novas residências em resposta ao aumento de demanda por trabalhadores.

O território, nesse caso, tem efeito sobre as diferentes redes onde as atividades urbanas participam e também é afetado por esse processo. Esse conceito é apropriado nesta pesquisa para que seja possível a construção de uma nova representação do processo de transformação espacial e de uso do solo urbano levando-se em conta as relações espaciais, estruturais, demográficas e socioeconômicas.

O perfil de uma cidade, ainda mais no caso de Itá, onde essa transformação se deu de forma tão contundente, dificilmente pode ser avaliado com apenas um método de estudo. A avaliação nesse caso é construída por um conjunto de instrumentos de análises onde cada uma pratica diferentes abordagens sobre o objeto a ser medido e testado. Esse processo leva a uma compreensão mais completa sobre as variáveis que estão sendo avaliadas já que procura explicitar as propriedades urbanas através de diferentes conteúdos.

A organização de um sistema urbano evolui de acordo com as necessidades da sociedade. Essas modificações são identificadas em suas características físicas como intensidade de ocupação urbana e desenvolvimento de seu tecido. Cada decisão de alocação de atividades é tomada considerando a estrutura urbana existente que limita a capacidade de decisão de outras atividades pelo uso do espaço ou das relações estabelecidas assumindo um comportamento sistêmico.

Em um Sistema Urbano ocorre uma relação funcional entre os agentes gerando propriedades coletivas complexas. Dessa forma foram aplicadas técnicas de avaliação diferenciadas que pudessem trazer à tona elementos considerados fundamentais para identificação das propriedades urbanas como sua organização e formação de estruturas.

Através das técnicas de análise aqui utilizadas, foram captadas características como, por exemplo, formação de comunidades, geração de centralidades relacionadas à proximidade, grau de intermediação e detecção de centros. Identificou-se a fragmentação das formas nas três fases analisadas, em função disso os valores de Geometria Fractal acabaram crescendo à medida que os sistemas foram de desenvolvendo e as interações internas e externas (crescimento econômico) se tornaram mais contundentes. Por outro lado, em função da necessidade de adaptação ao sítio o crescimento trouxe consigo a reduzida dependência espacial que aparece também no baixo índice de Moran, quando aplicada estatística espacial nos dados primários do Censo IBGE 2010.

As análises aqui utilizadas se mostraram complementares trazendo à tona características variadas como a organização interna, dependência espacial, comportamento dos sistemas, estrutura espacial, agrupamento e forma, abrindo especulações sobre futuras aplicações em diferentes estudos, principalmente aqueles que considerarem a estrutura urbana como parte de um processo evolutivo com características emergentes ao longo do tempo.

VIII Jornadas Internacionais "Grandes Problemáticas do Espaço Europeu"

Quando:
31 de Maio e 1 de Junho

Onde:
Porto - Faculdade de Letras - Anfiteatro Nobre

Num espaço europeu muito heterogéneo, mas também polifacetado e cheio de potencialidades, tem-se assistido ao acentuar das desigualdades e ao agravar dos problemas, institucionalizando-se uma crise generalizada, transversal a todos os setores. Para a dinamização do território europeu, num quadro onde a mudança construtiva esteja presente, urge analisar as dinâmicas propiciadoras dessa revitalização, implementando estratégias estruturantes, conjunturais, inovadoras e sustentáveis, que mitiguem os problemas e valorizem este espaço.

Neste evento internacional em que as pluralidades territoriais e culturais estão patentes, privilegia-se uma abordagem multidisciplinar e interuniversitária, apostando-se em territórios bem diferenciados, mas, sobretudo, em estratégias de desenvolvimento em que a inovação, o empreendedorismo, a complementaridade e a sustentabilidade estão patentes. Assim se potenciam os recursos endógenos e o património distintivo, repensando as políticas territoriais numa perspetiva em que se conjugam as sinergias tendentes à preservação do ambiente, ao ordenamento do território, à coesão social e à recuperação económica.

Temas:
1 - Sociedade e desenvolvimento
2 - Territórios da ruralidade: potencialidades e novas oportunidades
3 - Periferias e dinâmicas territoriais
4 - Turismo, cultura e património - uma estratégia inclusiva
5 - O reordenamento territorial em contexto urbano
6 - Ambiente e sustentabilidade(s)
7 - Ensino e multidisciplinaridade

Sustainable Development and Planning 2013

6th International Conference on Sustainable Development and Planning



Quando:
27 - 29 May, 2013

Onde:
Kos, Greece

Sustainable Development and Planning 2013 aims to bring together scientists and other stakeholders from across the globe to discuss the latest scientific advances in the field, as well as to seek and highlight developments in managerial strategies and assessment tools for policy and decision makers.

The conference addresses the subjects of regional development in an integrated way as well as in accordance with the principles of sustainability. It has become apparent that planners, environmentalists, architects, engineers, policy makers and economists have to work together in order to ensure that planning and development can meet our present needs without compromising the ability of future generations.

In many countries there has been an increase in spatial problems that has lead to planning crises. Planning problems are often connected with uneven development, deterioration of the quality of urban life and destruction of the environment. The increasing urbanisation of the world coupled with the global issues of environmental pollution, resources shortage and economic restructuring are leading to major crises.

Problems of environmental management and planning are not restricted to urban areas. Environments such as rural areas, forests, coastal regions and mountains face their own problems that require urgent solutions in order to avoid irreversible damage. The use of modern technologies in planning gives us new potential to monitor and prevent environmental degradation.

Conference Topics
- Regional planning
- City planning
- Sustainability and the built environment
- Cultural heritage
- Environmental management
- Resources management
- Social and political issues
- Rural developments
- Sustainable solutions in developing countries
- Transportation
- Energy resources
- Environmental economics

De Montgat a la Barceloneta. Frentes marítimos diversos

Quando:
26 mayo 2013

Onde:
Barcelona - CCCB

Programa
El paseo se inicia con el traslado al punto de salida desde el centro de Barcelona con el tren de cercanías RENFE hasta bajar en la estación de Montgat (barrio de Les Mallorquines).

Desde Montgat hasta el río Besòs es muy relevante la alternancia entre frentes urbanos consolidados y sectores industriales situados en primera línea de mar. De los primeros, destaca la rambla de Badalona, que es la calle de la fachada marítima del casco antiguo de la ciudad. Y de los segundos, el complejo de generación eléctrica en Sant Adrià de Besòs con las tres chimeneas. Una vez cruzado el Besòs, dos operaciones urbanísticas sirven para fechar la transformación urbanística del frente urbano barcelonés: el Fòrum (2004) y la Vila Olímpica (1992). El Poble Nou, situado en medio de los dos anteriores, se ha ido acercando también hacia el mar. El recorrido finaliza en el barrio de la Barceloneta. Este ha sido desde su fundación, en el siglo XVIII, el barrio marinero y portuario de la ciudad. En la actualidad se está adaptando al nuevo reto que supone la llegada del ocio y del turismo masivos.

Distancia aproximada recorrida en bicicleta: 12 km.

Cities and the economic recession since 2008

Lessons from previous crisis - Case studies from Barcelona, Munich, Turin and policy lessons from EU and Asien cities


The combination of the 1970s oil crisis and the opening up of regional markets to global trade in the 1980s and 1990s led to a profound restructuring of local production systems that had previously driven European industrial and economic expansion for almost a century. As a result, cities that were once the economic and political hubs of their respective regions and the drivers of their nation’s development faced a period of steep economic and social decline. These cities were faced with a new set of challenges. The legacy of cities ‘old economy’, the economic niche they occupied within the global division of labour and the unfolding of the ‘new economy’ were challenged by rapid technological change, globalisation and the emergence of high-tech, service and knowledge industries.

It is within this context that in 2010 LSE Cities carried out research to examine comparative patterns of decline, adaptation and recovery of a range of EU Metropolitan Regions that have successfully managed to transform their economies during the last major economic crisis to befall Europe since the 1970s and 1980s.

Conducted in collaboration with the Brookings Institution, the main objective of the research project is to illustrate successful examples of economic transformation that can be used by city leaders, policy makers and practitioners to stimulate debate about the transfer of innovative ideas and approaches needed to rebalance post-recession economies.

Three cities have been identified for the study as exemplar models of transformation. These include Munich (Germany), Torino (Italy) and Barcelona (Spain). The findings of our research will be presented in the forthcoming publication entitled ‘Transforming Urban Economies. Policy lessons from European and Asian cities’ to be published by Routledge in 2013.

Munich, Torino and Barcelona each tell a distinct story about the next urban economy; none have been perfectly successful, but each has made decisive progress, out-performed their peers and created opportunities for future growth, trade and job creation. The experience of many metropolitan areas underpins and reinforces what US cities and many other cities elsewhere already know and have taken a lead on: economic growth stems from primary importance being placed on a good business climate and environment for investment; the need for connectivity and productive infrastructure; an essential entrepreneurial spirit and corporate presence that provides the backbone of a dynamic economy; and a depth and range of anchor institutions.

In addition to these lessons, now we have key insight into what makes EU cities economically dynamic that, in turn, builds on our prior knowledge of the policy platform that allowed EU cities to overcome previous periods of crisis. These are:

Active, aligned and intentional partnership with government, private sector and institutions; Internationalisation, global positioning and trade; Knowledge economy, innovation-based entrepreneurship and modernisation of manufacturing; Strong link between human capital and attractive, distinctive cities; and Green economy, resource efficiency and decarbonisation. An in-depth analysis coupled with empirical examples of these policy lessons from previous crisis, which was presented at the 2010 Global Metro Summit in Chicago can be downloaded here.

European Metromonitor

The European Metromonitor project draws on LSE Cities' current research on the economic resilience of European Cities in order to establish an interactive exchange platform for the dissemination of key findings and case studies relating to metro-level responses to the economic crisis.
The platform aims to engage EU city leaders, policy makers, practitioners, researchers, the third sector and the public through an interactive dialogue that synergistically explores best responses and adaptation strategies of cities to the crisis.

ÍNDIA - Why small towns are lagging behind?

BY NEHA VERMA
MARCH 31, 2013
POSTED IN: ARCHITECTURE & PLANNING

There are 4,378 urban centres that have the 285 million urban citizens of the country. Of these there are 35 cities that have more than 1 million people and together account for 107.88 million people. That means the remaining 177.12 million or more than half of the total urban population of the country lives in small-sized towns or urban agglomerations. Even half of the population lives in small-sized town, the bigger cities become the magnet for populations that emerge from impoverished and infrastructure deficient rural and urban areas.

The reason for the skewed population distribution and its consequent burden on existing urban infrastructures is caused by lack of investment in the smaller towns. As we know that there is considerably large population living in rural areas, the development of smaller towns that are closer to these habitats would allow for a more balanced economic growth. Generally, there has been a bias within urban studies against small towns, where the idea of the ‘urban’ has always been seen to be ideally manifested in the big city. Large investments in big cities have often been justified as they are perceived to be ‘engines’ of development and growth. Even in cultural terms, the big city has always been glorified, as a space where conditions of modernity come together to develop art and a more sophisticated form of living. Yet, many scholars of cities still glamorize big cities and tend to influence the shape of imaging urban futures. While in reality, not only are smaller towns more manageable, they also have a more intimate relationship with their surrounding regions and more often than not, these contiguities are what sustains their economies. A country such as India with a significantly high rural population would do well to shift the focus of urban investments to these smaller townships. With new communication and transport technologies, there is no reason to believe that those spaces cannot also become important centres of art, culture and commerce and help us transform our notions of emerging India.

O Ciclo de Conferências e de Conversas Públicas 'A Cidade Resgatada' aprofunda o debate, iniciado em 2012, sobre os processos de Regeneração Urbana, à escala nacional e internacional. Com este debate não se pretende apenas “resgatar” o protagonismo dos centros consolidados; deseja-se abarcar a cidade mais alargada, sobretudo as franjas e os vazios pós-industriais, procurando perceber o seu papel estratégico nessa regeneração. Deseja-se, enfim, que esses processos sejam participados e debatidos interdisciplinarmente, englobando os contributos do Urbanismo, da Arquitectura, do Paisagismo, da Geografia, da Sociologia e da Antropologia.

Este ciclo acompanhará outras iniciativas concretas, como a realização de um Concurso Público e de um Seminário Internacional, os quais concentrarão o debate em áreas urbanas concretas, tendo o tecido do Porto como caso-de-estudo.

Helder Sousa apresentará o projecto fotográfico "Unfinished Projects".

"Valongo é um concelho periférico da Área Metropolitana do Porto. O seu rápido desenvolvimento ocorrido nos últimos 20 anos deu origem a um fenómeno que se encontra um pouco por todo o concelho. Assim como em tantos outros concelhos periféricos foram construídos edifícios de habitação que visavam acolher novos moradores e os trabalhadores da grande cidade. Publicitava-se uma melhor qualidade de vida, com espaços verdes e maior tranquilidade a preços convidativos e com boas acessibilidades. Tinha-se construído uma autoestrada e modernizado a linha de caminho-de-ferro. Neste clima de expectativas positivas, a planificação urbana do concelho correspondeu com a classificação de elevadas quantidades de solo a urbanizar.
O ciclo imobiliário rapidamente se inverteu, deixando sem procura a “sobre construção” do período da euforia. Em várias freguesias do Concelho encontram-se diferentes edifícios de habitação que nunca foram acabados. Neste contexto, Unfinished Projects é um projeto de fotografia documental que pretende documentar esta realidade que faz parte da paisagem urbana deste concelho há mais de 10 anos. Existem e coabitam no mesmo espaço, edifícios habitados e inacabados, compondo uma paisagem entre a disfunção e a “predação”; uma espécie de ecossistema do abandono onde a natureza rapidamente se insinua com espécies infestantes na linha da frente. Unfinished Projects opera como uma metáfora da crise económica contemporânea."
