Vila da Barca, das palafitas ao conjunto habitacional: análise sobre a (im)permanência dos moradores na área

Este trabalho apresenta uma reflexão sobre a atual orientação da política habitacional brasileira de intervir em áreas de assentamentos precários, sem a remoção dos moradores, de modo a garantir sua permanência nos locais infraestruturados. O eixo da investigação gira em torno da seguinte questão: em que medida a atual orientação da política habitacional brasileira de intervir em áreas de assentamentos precários, sem a remoção da população, garante efetivamente a permanência dos moradores nos referidos locais, particularmente no Projeto de Urbanização e Habitação da Vila da Barca. O estudo apóia-se em referenciais teóricos sobre a produção da cidade capitalista e a desigualdade de apropriação do solo urbano, processos estes que impactam diretamente na constituição dos assentamentos precários como espaço de moradia para as frações da classe trabalhadora brasileira, que não conseguem acessar o mercado privado da habitação, dado os mecanismos de formação de preços da terra urbanizada. A pesquisa foi desenvolvida com base no método dialético, tendo como procedimento metodológico o levantamento bibliográfico, documental e de campo, sendo entrevistados 35 moradores que foram remanejados pelo projeto urbanístico da Vila da Barca. Os resultados apontam que as formas precárias de moradia popular constituídas em áreas insalubres e inadequadas, como os cortiços, as favelas, e, no caso de Belém, as baixadas, historicamente, foram removidas de forma repressiva pelo poder público. Entende-se que os projetos urbanísticos padronizados desenvolvidos na atualidade e voltados para o atendimento da necessidade de moradia dos trabalhadores, ainda que apresentem em sua configuração o tema da permanência, preservam os interesses da produção da cidade capitalista e evidenciam a lógica de segregação sócio-espacial, pois não imprimem mudanças substantivas na realidade das famílias. Além disso, ao contrário do que é propagado pelo discurso estatal, a pesquisa realizada na Vila da Barca, demonstra que tais projetos não conseguem garantir a fixação dos moradores nos locais de intervenção, uma vez que desarticulam as estratégias de sobrevivência das famílias, que sem condições financeiras e impossibilitadas de arcarem com os custos da nova moradia (taxas de serviços urbanos), tendem a vender os imóveis que lhes foram destinados, reproduzindo em outros assentamentos precários as condições anteriores de vida. Desta forma, o Projeto da Vila da Barca, concebido para resolver a situação de moradia das famílias da área, gerou graves consequências para as mesmas, em especial, a desestruturação das atividades ocupacionais, demonstrando os limites da intervenção estatal de acordo com a lógica de produção da cidade capitalista.

Nebraska Farmland Markets Plateau

After several years of successively rising land values and cash rents, Nebraska’s farmland markets throttled back during 2008. Preliminary results from the University of Nebraska-Lincoln’s 2009 Nebraska Farm Real Estate Market Survey show a clear picture of the market mood turning very cautious in response to the U.S. and global economic downturns. As of February 1, 2009, the weighted average value of Nebraska farmland was $1,424 per acre, identical to the year-earlier level (Figure 1 and Table 1 at end of article). Likewise, estimated 2009 cash rents are stable to slightly down from 2008 levels throughout most of the state.

La conformación del mercado, la evolución de los precios y los efectos de la privatización de la tierra pública durante la expansión de la frontera en el sureste cordobés

En este artículo se analizan la conformación del mercado y los precios de la tierra del departamento Unión de la provincia de Córdoba, entre 1860 y 1880. Por una parte, se revisan los instrumentos desplegados por el Estado para llevar adelante la privatización del suelo y cómo se manifestaron en los valores de la tierra pública, la evolución que mostraron durante el período abarcado y la relación que tuvieron con las condiciones de venta de esos inmuebles. Por la otra, el seguimiento se practica sobre las tierras negociadas entre los particulares. Un primer nivel de análisis corresponde al precio medio anual. A través de este indicador se busca identificar las principales tendencias que mostró a lo largo de los años indagados. Luego, se profundiza el estudio mediante la descomposición del conjunto de los inmuebles en dos categorías: estancias y terrenos. Estos últimos, a su vez, se subdividieron en tres grupos de acuerdo con la superficie de cada uno y en relación con su posible destino económico

Desigualdad social en la "Ciudad Negocio": El modelo inmobiliario en la construcción social de Madrid durante el desarrollismo

El objetivo de esta Tesis doctoral es arrojar más luz sobre los mecanismos a partir de los cuales se dibuja el mapa de la desigualdad social en los sistemas urbanos contemporáneos. Para ello, en primer lugar se ha realizado una revisión crítica de los diferentes planteamientos desde los que se abordan los procesos de formación del espacio social urbano. A partir de ahí se ha aplicado el campo teórico analizado a un caso concreto muy representativo, el espacio social del Madrid de finales del siglo XX, comprobándose cómo los planteamientos tradicionales muestran carencias en cuanto a la explicación de los procesos estudiados. Por otro lado, una vez constatado que el espacio social madrileño producto del régimen de acumulación fordista destaca por un dibujo especialmente clasificado y jerarquizado, se ha analizado cuando y por qué comenzó este fenómeno de tan radical "clasificación social". Como resultado se obtiene que sólo es posible generar un discurso de explicación del espacio social estudiado considerando, por un lado, la percepción de la ciudad preexistente y, por otro, la concepción y construcción de la “planeada” por un modelo inmobiliario obligado a reconstruir en su mapa de precios una estructura social recién transformada. Una vez comprobado que la transformación que sufrieron tanto la estructura social como el modelo inmobiliario supuso un cambio de fase en la evolución de la ciudad y su espacio social se ha formulado un nuevo modelo urbano que se ha denominado “Ciudad Negocio” . En esta Ciudad Negocio destaca un modelo inmobiliario de venta de viviendas financiadas que, debido a sus propios mecanismos de funcionamiento, requiere de un espacio social muy ordenado, jerarquizado y estable que reproduzca la estructura social existente de forma visible. ABSTRACT The aim of this research project is to shed more light on the variables that draw the social inequality maps in the contemporary urban systems. For that purpose, a thoughtful review of the different theories around urban and social planning has taken place. The outcome of the analysis has been projected over a very representative sample, the social space in Madrid at the end of the 20th Century, proving the fact that traditional arguments do not explain the way the contemporary social patterns has been developed. On the other hand, once verified the fact that the social space in Madrid conceptually inherited from the Regulation School outlines a social hierarchy pattern, an analysis of the reasons that lead to such “social classification” has been performed. The research conclusions around the reviewed urban space can only be sustained by the perception of a pre-existing city and the boundaries of a real state pattern forced to match the prices to the newly transformed social structure. The transformation of the social structure and the real state model and its impact over the urban space has lead to a new urban model called “Business City”. This new urban product is built over a residential real estate market, which in nature requires of a very organised, socially classified and stabled pattern so that it mirrors the existing social structure.

Primeras políticas de vivienda en España y su influencia en la evolución de la tipología residencial: el caso de Benalúa (1883-1956)

El estudio del proceso de adaptación tipológica de las arquitecturas residenciales del barrio de Benalúa, una de las áreas consolidadas más singulares de la ciudad de Alicante (España), constituye un ejemplo clave para entender el alcance que tuvieron las primeras políticas de vivienda aplicadas en ese país, con anterioridad a la redacción de los Planes Generales que, en el transcurso del siglo XX, fueron ordenando las ciudades españolas y que en el caso de Alicante coincidió con la aprobación de la primera Ley del Suelo estatal (1956). De su análisis se obtienen las conclusiones que identifican los procedimientos que, por cambios sociales, políticos, de normativa o presión del mercado inmobiliario, condicionaron la evolución de la vivienda durante siete décadas, huellas que en la actualidad vienen desapareciendo a un ritmo vertiginoso, constatando el grado de intervención del Estado y de los municipios, así como su influencia y responsabilidad en la determinación de los tipos edificatorios.

Reclaiming Community? From Welfare Society to Welfare State in Australian Catholic Social Thought

Influenced by both conservative and left wing communitarian thinking, current debate about welfare governance in Australia reflects an inflated evaluation of the potential role of the third sector or civil society organisations in the production fo welfare. This paper gives an overview of twentieth century Australian Catholics social thinking about state, market and civil society relations in the production of welfare. It highlights the neglected, historical role of the Catholic Church in promoting a 'welfare society' over a 'welfare state' in Australia. It points to the reasons for the Church's later embrace of the welfare state and suggests that these reasons should make us deeply sceptical of the current communitarian fad.

Mudanças na relação entre estado e mercado na produção de habitação de interesse social em Parnamirim-RN

The formulation of public policies, particularly those relating to social housing – SH -, follow a dialectical process of construction, which are involved in the figures of the State and tha Market.The combination of the State and Market remains in constant tension and struggle for power, which provides beyond products (policies, programs and projects), periods of crises and disruptions that can give rise to new institutional arrangements. It is possible to verify a change in the relationship between the State and the Market in the formulation of public policies of SH financing, justified by the context of the Brazilian economy growth, especially after 2003, year that began the first Lula Federal Government , and through the international financial crisis (in 2008). Thus, the State and the Real Estate Market has been undergoing a process of redefinition of their interrelations, articulating new arrangements, new scales of action and new logics of financial valorization of urban space. This peculiarity demanded the rapid thinning of speech and the proposals in the reformulation of housing policies, with the primary result within the pre-existing Growth Acceleration Program – PAC -, the release of My House , My Life – PMCMV -, established by Law 1.977 of the year 2009. Given the above, this research has as study object the relationship between financing public policies of SH, promoted by the State, and behavior of Formal Housing Market. It is believed that the established roles for each agent in the new housing finance model introduced with the PMCMV, have been adapted according to the needs of each location to make this a workable policy. It remains to identify the nature of these adaptations, in other words, what has changed in the performance of each agent involved in this process. Knowing that private capital remains where there is more chance of profit, we tend to believe that most of the adjustments were made on scale of State action. The recommendation of easing urban legislation taken by PMCMV points to how the State has been making these changes in activity to implement the production of social housing by this program. We conclude that in the change for PMCMV, the direct relationship for construction and housing projects financing began to be made between the Caixa Econômica Federal bank and the builders. The city was liberated from the direct interlocutor role between all actors involved in the production of SH and could concentrate on negotiating with the parties, focused on the effectiveness of SH public policies proposed by PMCMV. This ability and willingness for dialogue and negotiation of municipal government (represented by their managers), undoubtedly, represents a key factor for rapprochement between State and Real Estate Market in the City of Parnamirim.

O Litoral e a metrópole dinâmica imobiliária, turismo e expansão urbana na região metropolitana de Natal-RN

The metropolitan regions of Northeast Brazil are being gradually included in a scenario of international investments, which are motivated by the restructuring of both touristic and real-estate sectors. The new capital, real-estate developers and space configurations that result from this process indicate the need for the creation and implementation of public tools which should, at least, allow the mitigation of the urban impacts and environmental losses resulting from this situation. The effects on landscape and on the socio-spatial configuration result from the intensification caused by the dynamism of the "real estate-tourism" sector. There is a regional integration as an expression of the urban expansion of the metropolitan area of Natal. This study investigates the uniqueness of the restructuring and territorial integration of coastal areas and the strategies of the circuit of capital accumulation formed by linking the real estate to tourism. It is intended to increase the understanding about the strategies of tourism, real estate and public policy agents involved in this territorial reconfiguration and in the fund-raising needed for the investments, to understand the existing social and environmental effects and their future trends and also to understand the forms of spatial production as results from the practices of approaching the land transformation and the tourism valorization of the landscape, in a synchronous manner, first in the Northeast region and, as a focal study, in the Metropolitan Area of Natal. Likewise, it is intended to apprehend the current processes of metropolization of the eastern coast of Rio Grande do Norte, in addition to indicate its physical-territorial transformation and the types of projects/developments promoted by the market in the recent period. Based upon analysis undertaken for the Metropolitan Region of Natal RN, this piece of work presents some considerations on possible legal instruments that can be adjusted to the municipalities which are experiencing the impact of this peculiar and recent phenomenon in the region, caused by the arrival of the real estate-touristic capital. It is also intended to point out basic proposals to the forms of public intervention, in a speculative way, starting from a Metropolitan Planning project within a medium and long term

Entre o cartão-postal e a cidade real: um estudo sobre paisagem e produção imobiliária em Natal/RN

Recent studies concerning the landscape have investigated the most important activities that contribute for its modification and have tried to better understand the society through the marks left by its quotidian. It is understood that singular landscapes constitute the cultural patrimonies of the cities, once they are part of the daily life of the citizens and are present in their social representations. Some contemporary authors defend the preservation of the natural and urban landscape trying, specially, to keep its importance for the local population. Natal is a city where the ambient qualities are well defined and known by the beauty of the area where it is located. Situated just between a river and the sea, the city grew following its geographic characteristics. The Potengi River, the Atlantic Ocean and the vast dunes ecosystem represented natural limits to the urban expansion; at the same time they have favored the development of a landscape pattern marked by the dialectic between the natural elements and the human interventions. However, this relationship changed after the intensification of the high rising development process that took place since the 1960s. The urban legislation tried to preserve the features of the local landscape delimiting Areas for Controlling Building High , destined to protect the scenic value of some parts of the city. On the other hand, the civil construction sector has made constant pressure in sense to abolish or to modify this legal instrument, aiming profits that have increased, in the 1990s, because of the consumption and the qualification of the urban space for tourist activities. It is necessary the raising of new elements to stimulate the quarrel about the landscape preservation, the process of the urban space production and the best way for the legislation implementation. This work tries to raise elements about the subject at local level, in sense to use Natal City experience to contribute for the formulation of indicators to raise the question about the lack of measure for subjective values, for example the cultural and affective value of the landscape. The natural elements inserted in the urban profile, represent strong visual references and supply identity to the town; they are part of the collective imaginary and are detached in the social context of the city. Then, why the preservation of the landscape, that estimates the improvement in the quality of life, is not enough to justify the controlling building high already previewed as part of Natal City Legislation? These questions send us to the approach of the landscape, as a community patrimony, alerting that some of its significant esthetics attributes must be preserved as a legacy for the future generations
