A industrialização como criadora de conjuntos habitacionais para o operariado: o caso do Bairro da Empresa de Cimentos de Leiria: Maceira-Liz

A Revolução Industrial consistiu num amplo conjunto de mudanças que ocorreu nos séculos XVIII e XIX na Europa, em que a grande metamorfose na sociedade sucedeu devido à substituição do trabalho manual pelo uso da máquina. Constituiu-se como fenómeno abrangente que congregou fatores demográficos, sociais, ideológicos, políticos e económicos. A busca de melhores condições de vida e de trabalho, foi fator decisivo para o aumento de população nos grandes núcleos urbanos, circunstância que determinou a procura de uma solução que resolvesse a questão do alojamento da classe trabalhadora. Surgiram assim teorias utópicas e sociais e também modelos urbanísticos dos quais se salientam: o Falanstério de Charles Fourier, Familistério de Jean-Baptiste Godin entre outros. Em Portugal, a industrialização ocorreu mais tarde que na restante Europa, assim como as evoluções e transformações associadas a esta. É neste contexto, que a partir do século XIX, o sector agrícola no país foi sendo gradualmente substituído pela indústria. O aumento da industrialização conduziu a um incremento da concentração de mão-de-obra próxima de grandes cidades industriais, ocorrência que fomentou o aparecimento dos primeiros núcleos habitacionais destinados à classe operária. A cidade sofreu, assim, alterações assinaladas por uma série de acontecimentos resultantes da Revolução Industrial, a par da falta de estratégias ligadas à questão da habitação para as classes desfavorecidas. É neste enquadramento que surge o Bairro do Pessoal da Empresa de Cimento de Leiria, Maceira-Liz. Este procurou responder às necessidades dos trabalhadores oferecendo-lhes boa qualidade de vida. Foi dotado de infraestruturas e equipamentos como a “Casa do Pessoal” ou a Cooperativa Abastecedora, entre outros, necessários ao bom funcionamento e permitindo uma maior sociabilidade entres os seus habitantes Desta forma, para demostrar a sua importância, introduz-se o Bairro do Pessoal da E.C.L no estudo do contexto internacional e nacional. Observam-se e criam-se relações com os modelos das cidades utópicas do século XIX e os conjuntos industriais em Portugal, detentores de alojamento destinado à classe trabalhadora, fazendo uma análise urbanística detalhada do Bairro do Pessoal de Maceira- Liz, uma “Utopia” construída segundo o espirito progressista do seu fundador Henrique Sommer.A partir do estudo dos fundamentos teórico-práticos, da forma de implantação e construção, bem como dos vários planos elaborados para este complexo - que demonstravam uma tentativa de inovar, através da construção de respostas às mudanças da sociedade e arquitetura em Portugal- poderá observar- -se que Maceira-Liz tinha alternativas para resolver a situação sócio- laboral dos operários e tentava resolver questões como a insalubridade da habitação operária da I República. O Bairro do Pessoal de E.C.L. ou Bairro de Maceira-Liz é um dos mais significativos exemplos de urbanismo do tipo fabril em Portugal, que permite fazer uma reflexão crítica e arquitetónica do papel que a arquitetura assume face à questão das diferenças sociais de classes, ao mesmo tempo que se propõe uma solução de revitalização do Bairro a fim de contribuir para a sua preservação e conservação da sua identidade; ABSTRACT: The Industrial Revolution consisted in a wide range of changes that occurred in the eighteenth and nineteenth centuries in Europe, where the great metamorphosis in society succeeded due to the replacement of manual work by the use of machinery. It was established as a wide-ranging phenomenon which gathered demographic, social, ideological, political and economic factors. The search of better conditions of life and work was a decisive factor for the increase of population in major urban centers, a circumstance that led to the search for a solution to solve the question of working-class housing. Thus, utopian and social theories emerged, as also as urban models, of which we stand out: the Charles Fourier Phalanstery, Jean- Baptiste Godin Familistère and others. In Portugal, the industrialization occurred later than in the rest of Europe, as well as developments and changes associated with this. It is in this context that, starting in the nineteenth century, the agricultural sector in the country had been gradually replaced by the industry. The increased industrialization has led to an enlarged concentration of labor work close to major industrial cities, occurrence that fomented the appearance of the first housing units for the working class. So, the city suffered changes shown by a series of events resulting from the Industrial Revolution, together with the lack of strategies linked to the issue of housing for disadvantaged classes. It is in this context that comes the Neighborhood “Bairro do Pessoal da Empresa de Cimento de Leirio, Maceira – Liz”. This tried to respond to workers’ needs by offering them good quality of life. It was gifted with infrastructure and equipment as the “Staff Home” or the Cooperative Supplying, among others, needed for a proper functioning and allowing a greater sociability among its inhabitants. So, to demonstrate its importance, the Quarter of the Cement Company is introduced in the study of national and international context. Relationships with models of utopian cities in the nineteenth and the industrial plants in Portugal, owners of housing for the working class, are observed and created, making a detailed and urban analysis of the Quarter of the Cement Company, a “utopia “ built according to the progressive spirit of its founder Henry Sommer . From the study of the theoretical and practical fundamentals, the way of implementation and construction, as well as the various plans drawn up for this complex - which showed a determination to innovate by building responses to changes in society and architecture in Portugal - it can be founded that Maceira -Liz had alternatives to solve the socio- labor situation of the workers and tried to solve issues such as the unhealthiness of the working room of the First Republic. The Quarter of the Cement Company is one of the most significant examples of the industrial type urbanism in Portugal, which allows a critical and architectural reflection of the role that architecture assumes in what concerns the social class differences issues, while it is proposed a revitalization solution for the Neighborhood in order to contribute to the preservation and conservation of its identity

Setting up a network of agrometeorological stations in East Timor

A developed and sustainable agriculture requires a permanent and reliable monitoring of climatic/ meteorological elements in (agro) meteorological stations which should be located close to agricultural, silvicultural or pastoral activities. An adequate network of meteorological stations is then a necessary condition to support innovation and development in any country. Developing countries, mainly those with a history of frequent conflicts, presents deficient number of weather stations, often poorly composed and improperly distributed within their territories, and without a regular operation that allows continuity of records for a sufficiently long period of time. The objective of this work was to build a network of meteorological and agro-meteorological stations in East Timor. To achieve this goal, the number and location of pre-existing stations, their structure and composition (number and type of sensors, communication system,… ), the administrative division of the country and the available agro-ecological zoning, the agricultural and forestry practices in the country, the existing centres for the agricultural research and the history of the weathers records were taken into account. Several troubles were found (some of the automatic stations were assembled incorrectly, others stations duplicated information regarding the same agricultural area, vast areas with relevant agro-ecological representativeness were not monitored …). It was proposed the elimination of 11 existing stations, the relocation of 7 new stations in places not covered until then, the automation of 3 manual meteorological stations. Two networks were then purposed, a major with 15 agro-meteorological stations (all automatized) and one other secondary composed by 32 weather stations (only two were manual). The set of the 47 stations corresponded to a density of 329 km2/station. The flexibility in the composition of each of the networks was safeguarded and intends to respond effectively to any substantive change in the conditions in a country in constant change. It was also discussed the national coverage by these networks under a “management concept for weather stations”.

Expansion of sunflower crop production in Brazil: a survey of future trends.

Sunflower cropped area in Brazil has been showing potential possibilities to be increased in a short period of time for biofuel production. Planning the activities is one of the requirements for the success of future cropped area expansion. This requires a previous survey that identifies future trends in the transformation and rearrangement of the sunflower agro-industry sector and also identifies technological needs that may affect this process. With the objectives of identify future trends and technological needs, a value production chain was built and a questionary was applied to agents of all the sectors participating at the V National Brazilian Symposium of Sunflower and at the XVII Sunflower National Research Meeting Network. The results pointed out a strong tendency for area expansion in the next two to five years (75%); being as a secondary follow-up crop (83%) specially after soybean and top be used for biofuel (77%). The main research needs were linked with disease control, crop zoning and varietal improvement for disease resistance and high oleic oil content. Also considering the vision of and concerns regarding the future expansion and transformation of the sunflower productive complex, it is believed that the expansion is a consolidated trend, requiring a strategic sector planning associated with an economic and technological police for its success within the Brazilian agribusiness.

Régime thermique en période de maturation du raisin dans le géoclimat viticole.

Mots clés :indice de fraîcheur des nuits, amplitude thermique, Système CCM Géoviticole, zonage, qualité. Key words: cool night index, thermal amplitude, MCC System for World Viticulture, zoning, quality. RESUME Le régime thermique en période de maturation du raisin est l?une des variables déterminantes de la coloration du raisin et de la richesse en arômes, anthocyanes et polyphénols des vins. L?objectif du travail est de caractériser le régime thermique, notamment la fraîcheur des nuits et l?amplitude thermique au cours de la maturation, au niveau du climat viticole mondial, sur une base des données de 100 régions viticoles dans 30 pays, obtenue par l?intermédiaire de l?Organisation Mondiale de la Météorologie - OMM. Plusieurs indices climatiques viticoles ont été calculés: l?Indice de Fraîcheur des Nuits ?IF (ºC), l?Indice Héliothermique de Huglin ?IH (ºC) et l?Indice de Sécheresse ?IS (mm) du Système de Classification Climatique Multicritères Géoviticole, et l?amplitude thermique moyenne en août et septembre Aa-s (ºC). Egalement, sur la période véraison-récolte ?v-r(moyenne des 30 jours précédant la date de récolte, estimée sur la base d?un Indice Héliothermique de HUGLIN égal à 1.900 - approximatif pour la maturation du Cabernet-Sauvignon): la fraîcheur des nuits (FNv -r), la température moyenne de l?air (Tv-r), la température maximale de l?air (Txv-r) et l?amplitude thermique (Av-r). Les résultats montrent que IH est corrélé avec Tv-r (r=0,79**) et avec Txv-r (r=0,80**). IH représente donc bien les conditions thermiques générales de la période de maturation en ce qui concerne la température moyenne et maximale de l?air. Mais IH n?est pas corrélé ni avec Aa-s ni avec Av-r. Par contre, IF est corrélé avec Aa-s (r=-0,70**) et FNv-r est corrélé avec Av-r (r=-0,69**). Cette corrélation doit justifier, en partie, l?usage assez courant de l?amplitude thermique comme indicateur de bonnes conditions thermiques de maturation pour les régions qui présentent des valeurs élevées. Mais ce raisonnement peut amener à des caractérisations erronées. Le travail met en évidence, également, ?importance de considérer le bilan hydrique des régions (IS) dans l?analyse du régime thermique sur la qualité du raisin. On peut onclure que pour avoir une bonne caractérisation du régime thermique en période de maturation il faut considérer la fraîcheur des nuits (IF étant un bon indicateur de FNv-r moyen des régions, avec un r=0,80**), caractérisation qui peut être améliorée avec l?information des températures maximales et de sur 11l?amplitude thermique en période de maturation du raisin. Les éléments présentés peuvent servir à améliorer les indices climatiques pour estimer le potentiel qualitatif du raisin des différentes régions viticoles, notamment en complément de IF. ABSTRACT The thermal conditions during the grape ripening period are important variables related to colour of the grapes, anthocyanins, polyphenols and flavour of the wine. The main purpose of this work was to characterise the thermal conditions, especially the night coolness and the thermal amplitude during maturation, in the geoclimate of the world vine culture. A database of 100 grape-growing regions of 30 countries obtained from the World Meteorology Organisation (WMO) was used. Some climatic indexes were calculated: Cool Night Index ?IF (°C), Huglin?s Heliothermal Index ?IH (°C) and Dryness Index ?IS (mm), from the Multicriteria Climatic Classification System for World Viticulture, and the thermal amplitude in August and September Aa-s (°C). Over véraison-harvest period ?v-r(mean of the 30 days before harvesting date, estimated on the basis of HUGLIN Heliothermal Index equal to 1,900 ? approximately value to ripen Cabernet-Sauvignon) similar indexes were obtained: the cool night (FNv-r), the mean air temperature (Tv-r), the maximal air temperature (Txv-r) and the thermal amplitude (Av-r). The results showed that IH is positively correlated with Tv-r (r=0.79**), Txv-r (r=0.80)and IF (r=0.67**). Therefore, IH represents well the general thermal conditions during maturation period, specially concerning the mean and the maximal air temperature. owever, IH was correlated neither with Aa-s nor to Av-r. IF was negatively correlated with Aa-s (r= -0.70**) and FNv-r was negatively correlated with Av-r (r=-0.69**). The correlation to some extent explains the current use of the thermal amplitude to predict good ripening thermal conditions for those regions that show high values. As here we have described, this thinking may give incorrect results. This work has also showed the importance to consider the water balance of the regions (IS) in the effect of the thermal conditions in grape quality. We conclude that the characterisation of the thermal conditions during the ripening period do need the cool night index (in this case, IFis a good index to provide the mean FNv-r of the regions, r=0,80**). Factors other than cool night which influence this characterisation are both maximal air temperature and thermal amplitude data. The elements presented in this work, in addition to IF , may improve the climatic indexes to be used to predict the qualitative potential of grapes from different regions.

Zonage climatique viticole et cartographie numérique du Rio Grande do Sul - Brésil, par les indices du Système CCM Géoviticole.

Abstract: The State Rio Grande do Sul is the main producer of Brazilian fine wines, with four viticultural regions. The objective is the characterization of the viticultural climatic potential of the State (total surface of 281.749 km2). The methodology use the Géoviticulture Multicriteria Climatic Classification System (Géoviticulture MCC System), based on three climatic indices ? Dryness Index (DI), Heliotermal Index (HI) and Cool Night Index (CI). Based on latitude, longitude, altitude and distance from Atlantic Ocean, the 3 viticultural climatic indices were modeled and the algorithms applied to a DTM using GIS. The results show that Rio Grande do Sul has the following classes of viticultural climate: according to DI ? Moderately Dry, Sub-humid, Humid; according to HI ? Cool, Temperate, Temperate warm, Warm and Very Warm; according to CI ? Cool nights, Temperate nights, Warm nights. Based on the total surface, the most representatives viticultural climates are: « Humid x Temperate » (3,1%), « Humid x Temperate warm » (14,4%), « Humid x Warm » (52,6%), « Sub-humid x Warm » (20,0%) and « Sub-humid x Very warm » (5,8%). According to CI, the viticultural climates have a range of variation as a function of the interaction between « earlyness of the varieties x heliothermal availability ».

ESQUEMAS DE ZONIFICACIÓN AMBIENTAL PARA LA PLANIFICACIÓN REGIONAL URBANA

La práctica y teorías de la planificación urbana han avanzado históricamente hacia  la  incorporación de  temas  y análisis  intersectoriales,  fundamentalmente aquellos en  relación con  la base  territorial y el ambiente. En materia de zonificación urbana se han  hecho esfuerzos por  incorporar  la variable ambiental a  la planificación urbana. El presente artículo hace un recuento general de  la evolución del concepto de zonificación tradicional  hacia  la    zonificación  ambiental  territorial,  la  macrozonificación  y  la zonificación  por  rendimiento.  Finalmente  plantea  el  acercamiento  metodológico planteado  como  parte  de  la  estrategia  de  la  Fase  III  del  Plan Nacional  de Desarrollo Urbano  de  Costa  Rica  en  relación  con  la  macrozonificación  por  rendimiento,  como ejemplo de  la puesta en práctica de  las más  recientes herramientas en  la planificación urbano- regional de un Área Metropolitana (PRUGAM). Abstract:The Urban Planning practice and  theory  has  historically developed  towards the inclusion of more comprehensive themes and analyses, fundamentally those that are environmentally  and  territorially  related. Within  this  context,  urban  zoning  has made significant efforts  to  incorporate the environmental component  in planning. The article makes  a  general  account  of  the  evolution  of  zoning  from  its  traditional  form  to environmental land zoning, macro zoning and performance zoning. Finally it establishes the  Costa  Rica’s National Urban Development  Plan methodological  approach  for  its phase III with regards to performance macro zoning as an example of putting the more recent  zoning  and  planning  theories  to  practice  in  a  regional  Plan  for  a metropolitan area.

ANALYSE THE VULNERABILITY IN THE MARANHÃO ILHA, BRAZIL, USING GIS TECHNIQUES AND GEOSPATIAL INFERENCE

Vulnerability and sustainability studies of an area help to assess both its level of exposure and capacity to support possible environmental impacts, and it is of primordial importance for proposals of the Legislation on Zoning, Allotment, Land Use/land cover, aiming to stimulate those areas indicated for urban growth, to discourage growth of overcrowded areas, to detect sections with restrictive use, as well as districts for permanent protection. This paper aims to analyze the vulnerability in the Maranhão Ilha, using GIS techniques, geospatial inference intersected with relevant social-environmental indicators.Estudos de vulnerabilidade e de sustentabilidade de uma área ajudam a avaliar o seu grau de exposição e sua capacidade de suporte a possíveis impactos ambientais, sendo fundamental para propostas de Lei de Zoneamento, Parcelamento, Uso e Ocupação do Solo, tendo por finalidade orientar as áreas onde deverá haver estímulo para o crescimento urbano; contenção da malha urbana; detecção de locais com possibilidade de uso restritivo, bem como locais de proteção permanente. Este trabalho propõe analisar o índice de vulnerabilidade a perda de solo da Ilha do Maranhão com base na metodologia proposta por (CREPANI, et al. 2001) e em técnicas de inferência espacial com apoio na AHP (Análise Hierárquica de Processo).

Climatic groups in Ibero-America viticulture compared to worldwide wine producer regions.

The wine production is an important activity in many Ibero-American countries. The wine producer regions of these countries configure a large use of different climate types and viticultural climates. In a vitivinicultural zoning project of CYTED (Ibero-American Program for Science, Technology and Development), a viticultural climatic characterization was done in this macro viticultural region. The project have assembled a climatic database that characterizes the viticultural regions, including relevant variables for viticulture: air temperature (mean, maximum, and minimum), precipitation, relative humidity, solar radiation, number of sunshine hours, wind speed, and evapotranspiration. Using indices of the Geoviticulture MCC System (HI, CI and DI), more than 70 viticultural regions in different countries (Argentina, Bolivia, Brazil, Chile, Cuba, Spain, Mexico, Peru, Portugal and Uruguay) were characterized according to its viticultural climatic. The results, which will be integrated to the worldwide database of the MCC System, showed that the Ibero-American viticulture is placed in a wide range of climatic groups of the wine producing regions around the world. This article presents the climatic groups found in Ibero-America, identifying also some new climatic groups not yet found in other regions of the world. This work also identifies some climatic groups not found in Ibero-America viticulture. The research has also highlighted viticultural areas characterized by climates with ?intra-annual climatic variability?, with the potential to produce more than one growing cycle per year. The results allow to conclude that the wide variability and climatic diversity present in Ibero-America may be one of the reasons to explain the diversity in terms of wine types, sensorial characteristics, typicity and uniqueness of wines produced on this macro-region.

LA ZONIFICACIÓN DE AMENAZA POR INUNDACIÓN COMO HERRAMIENTA PARA EL ORDENAMIENTO TERRITORIAL EN EL VALLE DEL RÍO SIXAOLA

En el caso de Costa Rica, uno de los eventos naturales que reviste especial importancia por su  frecuencia y daños acumulativos son las inundaciones; una herramienta para reducir los constantes desastres es la zonificación de amenazas por inundación. Mediante esta técnica es posible orientar el ordenamiento territorial y facilitar la gestión del riesgo. La cuenca del río Sixaola es una de las más afectadas por inundaciones en Costa Rica, en la parte baja se ubican asentamientos humanos habitados principalmente por núcleos de población altamente vulnerables. En este artículo se presenta la zonificación de amenaza por inundación, elaborada para el río Sixaola. ABSTRACT In the case of Costa Rica, one of the natural events of particular importance because of its frequency and cumulative damage is flooding. A tool to reduce this ongoing disaster is flood hazard zoning. Using this technique it is possible to guide land use planning and facilitate risk management. The Sixaola River Basin is one of the most affected by flooding in Costa Rica, and inhabitants of villages in the lower settlements are highly vulnerable. This article presents the flood hazard zoning plan developed for the Sixaola River.

PROPUESTA DE ZONIFICACIÓN TURÍSTICA COMO MODELO DE PLANIFICACIÓN TERRITORIAL PARA COMUNIDADES DEL GOLFO DE NICOYA

El proyecto “Diseño de productos y rutas turísticas alternativas para el mejoramiento del nivel de vida de las comunidades locales: el caso del Golfo de Nicoya” tiene como propósitos: la elaboración de un diagnóstico del sistema turístico de las comunidades involucradas, la evaluación del potencial turístico de los recursos y atractivos identificados en las comunidades, el diseño de productos y rutas turísticas, y la realización de una zonificación turística en las áreas de estudio. El presente artículo se centra en la zonificación turística de las comunidades metas, debido a que las variables anteriormente mencionadas son la base para su elaboración. La zonificación toma en cuenta los aspectos que condicionan los procesos de transformación y articulación del turismo en el territorio, desde el papel de los recursos naturales para la implantación turística y la influencia de la estructura territorial y socioeconómica sobre la que se organiza el turismo. Esta permite un mejor análisis del espacio geográfico y diseño de propuestas de desarrollo. En este caso, se identifican elementos homogeneizadores del espacio turístico a partir del diagnóstico de las comunidades, entre ellos se encuentran: la geomorfología, uso del suelo, tipología de recurso y atractivo turístico, la oferta y la demanda turística, entre otros. ABSTRACT The purpose of the project, “Design of Products and Tourist Route Alternatives for Improving the Standard of Living of Local Communities: The Case of the Gulf of Nicoya”, is to diagnose the system of tourism in the communities involved, evaluate the tourist potential of the resources and attractions of the communities, design products and tour routes, and establish tourist zones in the areas of study. This article focuses on the community goals of the tourist zones since the above-mentioned variables are the basis for their development. The zoning takes into account the aspects that condition the process of transforming an area into a tourist zone, from the role natural resources play in establishing tourism to the influence of socioeconomic and territorial structures. This allows a better analysis of the geographic space and design of development proposals. In this case, homogenous elements of the tourist space are identified from diagnosis of the communities, including the geomorphology, land use, typology of resource and tourist attractions, tourist supply and demand and other factors.

Da Placentia a Placencia Trasformazione della morfologia urbana di Piacenza dall'eta tardoantica all'alto Medioevo

La presente ricerca, focalizzata sull’evoluzione di Piacenza tra età antica e altomedioevo, si mette nel solco del dibattito sull’archeologia urbana sviluppatosi in Italia a partire dagli anni Ottanta del Novecento. Dopo la raccolta dei dati di scavo negli archivi della Soprintendenza e delle testimonianze delle fonti scritte è stato creato un geodatabase che potesse gestirli in maniera integrata. Lo studio è stato svolto per temi trasversali che prendessero in esame lo sviluppo dei diversi aspetti di Piacenza dalla fondazione al IX secolo, per poi restituire in fase di conclusione dei quadri sincronici relativi alla città romana, tardoantica e altomedievale. Il quadro che si delinea dallo studio condotto è quello di una città che, seppure interessata dalle vicende storiche che hanno coinvolto buona parte del nord della penisola, tra la tarda Antichità e l’alto Medioevo, mostra sia fenomeni che la accomunano alle altre realtà urbane regionali e extraregionali, sia caratteristiche specifiche scarsamente riscontrate altrove. L’età carolingia è il periodo nel quale il caso piacentino si presenta maggiormente denso di spunti per il tema dell’urbanesimo. Su questo Piacenza, soprattutto per il tramite delle fonti scritte, offre uno spaccato che poche altre città possono dare e che sarebbe ulteriormente implementabile con nuove e mirate ricerche archeologiche.
