Breu Branco é um município do estado do Pará, localizado na microrregião do lago de Tucuruí. Ao longo dos anos o município experimentou um crescimento populacional acelerado, consequência da migração de pessoas oriundas de outras regiões em busca de trabalho e moradia próximos às obras de barragem. O crescimento espacial tem forte relação com a Hidroelétrica. Além do fator populacional, outros três fatores foram importantes para o crescimento espacial de Breu Branco: o preço da terra, a topografia da área de expansão e a falta de políticas de proteção ambiental no município. Nesse trabalho utilizamos ferramentas cartográficas e sensoriamento remoto para a construção de mapas em três períodos 1996, 2006 e 2016. Os resultados obtidos mostram novas dinâmicas espaciais, como a duplicação da área urbana, saturação do núcleo projetado da cidade em direção ao norte, conversão de áreas de floresta e preservação (APP) em ocupações, concentração imobiliária e especulação sobre novas áreas, do ponto de vista populacional um aumento de 58% da população em vinte anos.Palavras-chave: Hidroelétrica.

Over the years, the municipality experienced an accelerated population growth, a consequence of the migration of people from other municipalities of Pará and the northeast region of Brazil in search of work and housing near the works. The spatial growth has a strong relationship with the implementation phases of the Tucuruí HPP. In addition to the population factor, three other factors were important for the Breu Branco spatial growth: the price of land, the topography of the expansion area and the lack of environmental protection policies the municipality. In this work, we used cartographic tools and remote sensing for the construction of maps in three periods 1996, 2006 and 2016. The results obtained show new spatial dynamics, such as the duplication of the urban area, saturation of the projected nucleus of the city towards the north, conversion of forest and preservation areas (APP) into occupations, real estate concentration and speculation about new areas, from the point of view. population view an increase of 58% of the population in twenty years. Keywords: Hydroelectric.Territory.

The City

The municipality of Belém is installed on low ground under a rich and immense system of surface waters that converge for the most part directly into the Pará River system, Marajó Bay, northern fathom of the Amazon River and then the Atlantic Ocean. The Guamá river (estuary) and Guajará bay stand out, bathing its western, north and northeast portions, and numerous tidal channels, as well as several streams converge on the former, as well as several swamps and temporary wetlands. The main urban nucleus, the city of Belém, was installed and continues to do so, along the tidal and igarapé channels, modifying its courses, and polluting them brutally, either by solid waste or by domestic effluents of all kinds without any treatment, in addition to industrial contributions, becoming more serious as the city moves forward in horizontal and vertical buildings. The tides partially assist in this cleaning, by carrying a large part of these pollutants daily to the Guamá River, from this one to the Guajará Bay and then Marajó and Atlantic. Beautiful beaches in the north and northeast of the municipality (Outeiro, Mosqueiro, Farol, Ariramba, Carananduba, Paraíso and Baía do Sol) attract thousands of visitors, which further contribute to general pollution. Although several surveys have already been carried out to assess these impacts and its dilution, it was decided to try a new attack, emphasizing the Tucunduba stream and its drainage in the Guamá river, the Guajará bay on its margin of strong industrial-port impact and then the beaches of the Baía do Sol. Water and solid sediment in suspension (suspended) were collected in three different periods, considering the two tidal cycles, in eight seasons. Measurements of the main physical parameters were made in loco. Next, cations and anions in the waters analyzed, mineralogical identification and chemistry of the suspensates, in addition to micromorphological analyzes were carried out. The results show that the Guamá river and Guajará bay can be still classified as unpolluted natural waters, similar to the white waters of the Amazon region. Tucunduba and the waters of the Baía do Sol, mainly those restricted (swamps and manholes) are strongly altered by human occupation. Cations and anions, as well as microplankton from the suspension sediments, also allow identify the seasonal interference of oceanic interference during the dry season. The suspension materials of these rivers are dominated by quartz, kaolinite, partly muscovite / illite, demonstrating a strong relationship with the sediments of the margins, gullies and flood plains, and also of the Barreiras Formation, Neogene in age, the geological unit that serves as a substrate for the lands of Belém municipality. However, for a more informed assessment, a systematic and much more comprehensive study is recommended from the chemical, biological, mineralogical point of view and still under strong seasonal and tidal cycle controls, preferably for a continuous decade.

Beautiful City

Guwahati derives its name from the Assamese word “Guwa” means areca nut and “Haat” means market. However, the modern Guwahati had been known as the ancient Pragjyotishpura and was the capital of Assam under the Kamrupa kingdom. A beautiful city Guwahati is situated on the south bank of the river Bramhaputra. Moreover, It is known as the largest city in the Indian state of Assam and also the largest metropolis in North East India. It has also its importance as the gateway to the North- East India. Assamese and English are the spoken languages in Guwahati.  In 1667, the Mogul forces were defeated in the battle by the Ahom forces commanded by Lachut Barphukan. Thus, in a sense Guwahati became the bone of contention among the Ahoms, Kochas and the Moguls during the medieval period.  Guwahati the administrative headquarters of Lower Assam with a viceroy or Barbhukan was made by the Ahom king.  Since 1972 it has been the capital of Assam. The present paper will discuss the changes happened in Guwahati over the period of late 1970s till the present time. It will focus on the behavior of people, transformed temples, Panbazar of the city, river bank of Bramhaputra, old Fancy Bazaar, chaotic ways, festivals and seasons including a fifth man made season etc. It will also deal how over the years a city endowed with nature’s gifts and scenic views, has been changing as “a dirty city”. Furthermore, it will also present the insurgencies that have barged into the city. The occurrence of changes will be discussed through the perspective and point of view of Srutimala Duara as presented in her book Mindprints of Guwahati.

Este trabalho objetivou analisar aspectos geoambientais de Caucaia, localizado no Estado do Ceará. O município vem apresentado nos últimos anos um elevado crescimento populacional, suscitando uma forte pressão sobre os recursos naturais, justificando assim a necessidade de se identificar as áreas mais e menos vulneráveis ambientalmente ao adensamento populacional, gerando com isto elementos para o planejamento territorial. Desse modo, procedeu-se a caracterização geoambiental criando os mapas de sistemas ambientais e de vulnerabilidade ambiental. Constatou-se que 21% do território têm alta vulnerabilidade à ocupação, sendo de 58% e 17%, respectivamente, os percentuais para os locais com média e baixa vulnerabilidade. Menciona-se que o planejamento territorial com base na compartimentação geoambiental surge como um importante delineador das condições organizacionais e da funcionalidade dos ambientes, tendo em vista que considera sempre suas características ambientais e sua dinâmica sócio-espacial de maneira integralizada.   A B S T R A C T   This study aimed to analyze geoenvironmental aspects of the city of Caucaia, located in the state of Ceará, Brazil. The municipality has presented in recent years a high population growth, raising a strong human pressure on natural resources, thus justifying the need to identify the most and least environmentally vulnerable areas to population density, generating elements for territorial planning. Thus, we proceeded to environmental characterization creating maps of environmental systems and environmental vulnerability Caucaia, scale 1:50,000, using, for both, the geosystemic theory and the use of remote sensing products, cartographic data and fieldwork. It was verified that 21% of the territory have high vulnerability to occupation, being 58% and 17%, respectively, the percentages for areas with medium and low vulnerability. It is mentioned that the territorial planning based on geoenvironmental compartmentation emerges as important eyeliner of the organizational conditions and functionality of environments, considering their environmental characteristics and socio-spatial dynamics in the integrated form.

This paper examines the acceptability of the implementation of a High Occupancy Vehicle (HOV) lane in the north of Bogota (Colombia), a strategy that is compatible with the policies of the mobility master plan of the city. Although the idea of using HOV lanes dates back to the 70's, it is still a valid alternative which is amply documented that produces positive impacts on travel times, accident rates, greenhouse emissions, among others. The study is based on discrete choice survey experiments which allowed calibrating a multinomial logit model. The calibrated model indicated that the acceptability of the HOV lane is very sensitive to travel times experienced by current car users. The model also identified the segment of the population with the highest acceptability for the proposal, which would consist of women over 31 years old, who travel for purposes related to work

Preliminary Phase

Este artigo apresenta alguns itinerários de campo da pesquisa etnográfica que desenvolvi no mestrado, na qual busquei a compreensão de como se dá a construção da inteligibilidade dos acontecimentos acerca da pichação/graffiti em Santa Maria. Trato sobre a fase preliminar da observação participante, a partir de uma loja de street art, experiência que sublinha a importância dos laços de reciprocidade e a lógica dos sistemas classificatórios (as maneiras de colocar o mundo em estrutura, de ordenar intelectivamente o caos sensível) na pichação/graffiti. Dessa experiência indoor, desdobram-se outros cenários de interação com pichadores/grafiteiros, pelas ruas, dentre os quais destaco um domingo na zona norte. A partir do trabalho de campo e de uma leitura pós estruturalista do estrtuturalismo, percebe-se as inversões, as recombinações e os transbordamentos semânticos das categorias binárias (legal/ilegal, limpo/sujo, certo/errado, luz/sombra, belo/feio, visível/invisível...) do ato universal de classificar e, sobretudo, diferentes maneiras de construir os sentidos de viver e de narrar a cidade, a partir da pichação/graffiti. Palavras-chave Pichação/graffiti. Sistemas classificatórios. Transbordamentos semânticos. Reciprocidade. Cidade. PICHAÇÃO/GRAFFITI IN SANTA MARIA:CLASSIFYING SYSTEMS, SEMANTICAL OVERFLOWS AND WAYS TO NARRATE THE CITY.   Abstract This article presents some itineraries of the ethnographic research that I developed in the master degree, in which I sought to understand the construction of the intelligibility of the events about the pichação/graffiti in Santa Maria. I write about the preliminary phase of participant observation, starting in a street art shop, an experience that underlines the importance of reciprocal ties and the logic of classificatory systems (the ways of putting the world in structure, of ordering the sensitive chaos intellectively) around the pichação/graffiti. From this indoor experience to other scenarios of interaction with pichadores/graffiti artists, through the streets, among which I highlight a Sunday in the north zone of the city. Since the fieldwork and a post-structuralist point of view about estrtuturalism, we can see inversions, recombinations and semantic overflows of binary categories (legal / illegal, clean / dirty, right / wrong, light / shadow, beautiful / ugly , visible / invisible ...) of the universal act of classifying and, above all, different ways of constructing the senses of living and narrating the city, around the pichação/graffiti. Keywords Pichação/graffiti.

Background:In October 2016, two major earthquakes occurred in Marche region in the Centre of Italy, that resulted in widespread damage. The second one strokes Norcia, Visso, Arquata del Tronto, Accumoli and Amatrice, causing a lot of damages to cultural heritage of the cities of Tolentino, San Severino, Camerino and Ascoli Piceno, where the church ofSanta Maria della Caritàis located.Introduction:The church has high historical, architectural and social value for the city of Ascoli Piceno, because it is the only one that is opened to the devotees all time in the day and night. From the structural point of view, the church has a long and important annex to the north, which was later built with respect to the church, and after the L’Aquila earthquakes (2009) damages, the church was subjected to a retrofit intervention, in order to obtain a better “box-like behavior”.Objective:This paper addresses how the relevant annex influenced the seismic response of this historical complex and how, more generally, this kind of asymmetric mass may affect the behavior of historic churches.Results and Conclusion:The results indicate that the presence of annex plays a significant role in the dynamic response of the church and affects the distribution of damages in the whole building. The results of the seismic simulation agree with the observed damage.

In ancient times, the city of Urfa suffered serious flood disasters due to the Karakoyun river which surrounded the city on the north and west sides. In order to prevent the recurrence of such disasters, in 525, the Byzantine Emperor Justinian had built a huge wall of stone (Justinian wall) to the northwest of the city that conducted the river to the north and east walls of the city. He also constructed an artificial channel and three bridges which are known as the Justinian system. This system has been used by the many civilizations that have occupied the city, since the 6th century. Each civilization added some new water structures to the system and carried out some renovations to it. The system, being still in use, defended the city against moderate size floods and survived for 1,500 years. In this paper, the Justinian system is evaluated from the hydraulic point of view together with its ongoing functionality. It is interesting that although the cultural structures of the civilizations settled in the city do not have the same characteristics, the water structures have similar features in terms of hydraulic and architectural perspectives.

Abstract. Sustainable Development have drawn much attentions to the direct or indirect relationships of land use/land cover changes in past recent years. Being a limited resource, Land is critical issue to manage by the city administration in absence of effective tool. Geospatial Techniques can solve this issues of sprawl modelling and can act as decision supportive tool. This study focuses on Surat and Lucknow Indian Cities, its surrounding area to delineate a metropolitan area with the use of geospatial technology. It encompasses the jurisdictions of various urban development authorities to provide a regional context of development for the year 2035. These cities have unique characteristic of development which is investigated using remote sensing technology. Temporal analysis of study area images has deployed that there is a pressing need to control the Development because of its incessant characteristic. Role of Remote sensing is found to be very vital to understand and measure the sprawl’s magnitude. Analysing the spatial dynamics of cities has escalated the need of policy making for controlled development. Insights of this study can be useful for framing policy at a regional or global level.

In the last century, the world has become an “urban world” and the cities began to concentrate a larger number of people (with over of 50% of global population living in the cities). Currently, the social-environmental challenges that the cities face, drive new alternatives to the contemporary urban planning. In those conditions, it is expected than the cities become the centers of changes and they find new possibilities in the urban planning field taking into account the concepts of resilience and sustainability during the elaboration of municipal policies. This case study research was conducted in the city of Bogota, capital of Colombia, and evaluated the Master Plan - MP (as instrument of urban planning), and the commitment to this plan, with the construction of resilience in a highly susceptible city to climate change. Also included many challenges such as, population dynamics, sprawling around the rural areas, mobility problems and infrastructure deficiencies, each one of them with the necessity of attention from the planning point of view. The objective of this research is to know in a qualitative way, whether the Master Plan has an orientation and how can this contribute to the construction of urban resilience. The methodolo- gy was developed in a previous research by Lemos (2010) and involved categories of sustainability and resilience, with the possible impacts of the actions described in the Plan. After the implementation of the methodology and the revision of the Plan, the results shown that the Plan is targeted to the resilience. However, its contribution is fragile in the definition of joint actions in the different levels of political power.KEYWORDS: Resilience; urban planning; climate changes; urban planning policiesEn el último siglo, el mundo se volvió un “mundo urbano” y las ciudades pasaron a concentrar un mayor número de personas (con más del 50% de la población mundial residiendo en las ciudades). Actualmente, los desafíos socioambientales que las ciudades enfrentan, impulsan nuevas alternativas para el planeamiento urbano actual. En esas condiciones se espera que las ciudades se conviertan en el centro de cambios y encuentren nuevas posibilidades en el área del planeamiento urbano teniendo en cuenta los aspectos de la resiliencia e la sostenibilidad durante la elaboración de la Política Municipal. Esta pesquisa se trata de un estudio de caso realizado en la ciudad de Bogotá, capital de Colombia, que evaluó el Plan de Ordenamiento Territorial – POT (como instrumento de planeamiento municipal) y el compromiso del mismo, con la construcción de resiliencia en una ciudad altamente susceptible al cambio climático, con muchos desafíos, como las dinámicas poblacionales, la expansión a lo largo de áreas rurales, problemas de movilidad y deficiencia en la infraestructura, cada uno con una necesidad de atención por parte de planeamiento en cuestión.. El objetivo de la investigación es conocer cualitativamente, si el Plan tiene una orientación y puede contribuir en la construcción de resiliencia urbana. La metodología usada fue desarrollada en la pesquisa previa de Lemos (2010) e involucra categorías de sostenibilidad y resiliencia, con los posibles efectos de las acciones descritas en el Plan. Después de la aplicación metodológica y la revisión del Plan, los resultados demostraron que el Plan está orientado para la resiliencia, sin embargo su contribución es frágil en la definición de acciones conjuntas en diferentes niveles del poder político.PALABRAS - CHAVEResiliencia; planea- miento urbano; cambio climático; políticas de planeamiento urbano.

Lublin developed rapidly at the turn of the 1960s and 1970s. Large residential districts were designed on rural areas surrounding the city. Lublin was expanded in almost every geographical direction, in accordance to the principles specified in the 1959 city master plan. The Kalinowszczyzna district was located in the north, covering local hills and ravines, and replacing the former farm and manor it was subsequently named after. The housing estates constructed there were erected mainly by means of prefabricated elements, and included both flats and shops. They also played cultural and administrative functions. The plan’s implementation was launched in 1963 and came to an end in 1980s. Kalinowszczyzna is currently one of 27 administrative districts of Lublin and constitutes an essential part of the city.
