Instruments for analysing urban conflicts in the Global South: The case of urban transformation processes in Dakar

Physical and social transformation processes that take place in urban contexts with strong spatial growth and hardly any economic development frequently have significant adverse impacts for the affected people, which tend to be made invisible. This paper presents an analytical framework to explore different ways to approach urban transformation processes (supply side), their impacts on the set of needs of the community (demand side) and their consequences on the urban environment as a whole (context). The proposed method has been used to assess three actions related to the physical and social transformation of the largest self-made settlement in the city of Dakar, Senegal, during the 2005–2012 period. Research findings show how exogenous interests are privileged over the common good when the affected citizens are not effectively involved in decision-making processes.

Influência das áreas verdes urbanas na temperatura e na umidade do ar em São Carlos-SP

A remoção da vegetação para dar lugar a edificações e superfícies pavimentadas implica na anulação de diversos serviços ambientais. Entre eles está o sombreamento, que impede a aquecimento do ar derivado da re-emissão da radiação solar pelas superfícies. O ar quente e seco contribui para o aumento da sensação de desconforto e favorece a incidência de doenças respiratórias. O objetivo deste trabalho foi analisar valores de temperatura e umidade do ar, comparando-se dados coletados por estações meteorológicas automáticas instaladas em regiões arborizadas e áridas da cidade, durante a ocorrência de episódios representativos do clima da região. Os procedimentos metodológicos, baseados na Climatologia Dinâmica, consistiram em relacionar a sucessão de tipos de tempo meteorológico de escala regional às diferenças observadas entre os pontos de estudo, provocadas por fenômenos provenientes das atividades humanas. Isto permitiu a clara identificação de variações climáticas críticas para o conforto e a saúde humanos, tais como grandes amplitudes térmicas e baixos valores de umidade do ar. Os resultados mostraram amplitudes térmicas menores nas áreas arborizadas (em média 3ºC) e, em alguns casos, umidade do ar mais elevada em comparação aos valores observados nas partes áridas estudadas. Estas verificações reforçam a afirmação da necessidade de ampliação das áreas verdes de São Carlos, que contribuem na atenuação as condições climáticas de desconforto e insalubridade. Em conseqüência, aumentam a qualidade de vida da população e as condições de sustentabilidade do ambiente urbano. Tal afirmação vem ao encontro da legislação ambiental brasileira e dos anseios da população são-carlense. Espera-se que as constatações deste trabalho sejam um elemento adicional na adoção de políticas públicas mais comprometidas com a saúde humana e ambiental.

Constructing, Creating and Contesting Cityscapes. A Socio-Anthropological Approach to Urban Transformation in Southern Xinjiang, People’s Republic of China

This manuscript is based on a PhD thesis submitted at the Institute of Social Anthropology at the University of Bern in 2014. The dissertation was part of the research project „Xinjiang Uyghur Autonomous Region and Chinese Territoriality. The Development of Infrastructure and Han Migration into the Region“ under the supervision of Prof. Dr. Heinzpeter Znoj and financed by the Swiss National Science Foundation SNSF. Madlen Kobi analyzes the architectural and socio-political transformation of public places and spaces in rapidly urbanizing southern Xinjiang, P.R. China, and in doing so pays particular attention to the cities of Aksu and Kaxgar. As the Xinjiang Uyghur Autonomous Region lies in between China and Central Asia, it is especially characterized by differing political, cultural, and religious influences, and, furthermore, due to its being a multiethnic region, by multiple identities. One might expect cultural and social identities in this area to be negotiated by referring to history, religion, or food. However, they also become visible by the construction and reconstruction, if not demolition, of public places, architectural landmarks, and private residences. Based on ethnographic fieldwork performed in 2011 and 2012, the study explores everyday life in a continuously transforming urban environment shaped by the interaction of the interests of government institutions, investment companies, the middle class, and migrant workers, among many other actors. Here, urban planning, modernization, and renewal form a highly sensitive lens through which the author inspects the tense dynamics of ethnic, religious, and class-based affiliations. She respects varieties and complexities while thoroughly grounding unfolding transformation processes in everyday lived experiences. The study provides vivid insights into how urban places and spaces in this western border region of China are constructed, created, and eventually contested.

Medical emergency alarm dissemination in urban environments

During medical emergencies, the ability to communicate the state and position of injured individuals is essential. In critical situations or crowd aggregations, this may result difficult or even impossible due to the inaccuracy of verbal communication, the lack of precise localization for the medical events, and/or the failure/congestion of infrastructure-based communication networks. In such a scenario, a temporary (ad hoc) wireless network for disseminating medical alarms to the closest hospital, or medical field personnel, can be usefully employed to overcome the mentioned limitations. This is particularly true if the ad hoc network relies on the mobile phones that people normally carry, since they are automatically distributed where the communication needs are. Nevertheless, the feasibility and possible implications of such a network for medical alarm dissemination need to be analysed. To this aim, this paper presents a study on the feasibility of medical alarm dissemination through mobile phones in an urban environment, based on realistic people mobility. The results showed the dependence between the medical alarm delivery rates and both people and hospitals density. With reference to the considered urban scenario, the time needed to delivery medical alarms to the neighbour hospital with high reliability is in the order of minutes, thus revealing the practicability of the reported network for medical alarm dissemination. © 2013 Elsevier Ltd.

Análise da problemática socioambiental de nascentes urbanas no município de Garanhuns-PE

Garanhuns City, in Pernambuco, undergoes a rapid, polluting and non-organized urban development affecting its freshwater springs around the urban environment. These sources are of great importance to the district as well as to the hydrographic basin of the Mundaú River. In this view, this paper aims at analyzing the socio-environmental problems resulting from the urban expansion surrounding the Garanhuns’ sources. The study considers the social and environmental dynamics and follows the theoretical contributions of socio-environmental geography proposed by Mendonça’s Urban Environmental System methodological and theoretical model (2004), as well as the conceptual values of Santos’ space theory (2002a). The data treatment included bibliographical and documental research, evaluation of environmental impact, and water analysis. It revealed that Garanhuns possesses many local environmental traits favoring the coming out of freshwater springs and that these sources have played an important role in the making and development of that village. The environmental impacts on freshwater springs, like Olho D’água, Bom Pastor, Vila Maria, Pau Amarelo and Pau Pombo have been evaluated through the environmental impact score IIAN. It put alight serious cases of socio-environmental impacts on the dynamics of the freshwater springs. In the period of April 2013 and April 2014, it monitored the superficial water quality expelled by the Pau Pombo, Pau Amarelo e Vila Maria water sources, and the analyses of the contents followed the determinations of the Environmental National Board, whose parameters are dissolved oxygen, biochemical demand of oxygen, nitrate, total coliforms, faecal coliforms, and electrical conductivity. The results recollected suggest the existence of organic pollution and deep alteration in the water coming out from the sources. In consequence, it seems important the putting out of measures destined to stop those impacts and guaranteeing protection and maintenance of the freshwater springs and their micro-basins.

O papel do ambiente residencial na qualidade de vida de idosos: um estudo exploratório em Cabedelo, Paraíba

Currently, the growing aging population challenges the society and public health policies, for increased longevity need to be associated with quality of life. Adequate physical and social environment are key factors for the welfare of the elderly, particularly the housing environment - this thesis understood as the home (dwelling unit) and its surroundings (close proximity). In addition, Brazilian legislation in this sector indicates the importance of the elderly remain at home and in the family. In addition, Brazilian legislation in this sector indicates the importance of the elderly remain at home and in the family. Based on this framework mortar, the thesis was starting questions: How do you live the elderly population aged 80 and over which is served by the Health Family Strategy of the Unified Health System? That social and environmental conditions of the place of residence act more directly on their quality of life? How do these people get housing conditions experienced? The research aimed to investigate how the residential environment (social and physical) influence everyday activities and quality of life of the elderly. Exploratory qualitative study highlighting the home visits, developed based on multimethod strategy. The empirical study was conducted in the city of Cabedelo-PB, Nov/2013 to Feb/2014. Participants were 36 elderly people (31 women and 5 men) aged between 80 and 99 years, little education, who live 39 years in the area (average). In the research first stage were applied questionnaires for socio-demographics and livability of the residence and the surroundings. In the second stage we used semi-structured interview and a tour accompanied in the neighborhood (with those who have accepted to do so). Throughout work it was kept a diary by the researcher and held naturalistic observations of the behavior of the elderly. Quantitative data were described using descriptive statistics, and information from the interviews were analyzed through the Collective Subject Discourse technique. Among the key ideas that emerged from them are: the representation of home, neighborhood support and related issues dyad independence / autonomy. The study showed that the elderly develop strong attachment to the place where he lives, the importance of it for your health and the desire to stay there. Thus, despite experiencing many barriers (more physical than the social), at the place where they live, they say they are satisfied, even when unfavorable conditions are evident. Concluding that as the houses are environmentally more docile, simple changes ensure autonomy, independence and mobility for the elderly. In turn, the barriers of the urban environment show it more difficult to deal with, making this space inhospitable to most survey participants, a condition that hinders your physical activities and social participation, and negatively influence their quality of life.

Presenting SAPUSS: solving aerosol problem by using synergistic strategies in Barcelona, Spain

This paper presents the summary of the key objectives, instrumentation and logistic details, goals, and initial scientific findings of the European Marie Curie Action SAPUSS project carried out in the western Mediterranean Basin (WMB) during September-October in autumn 2010. The key SAPUSS objective is to deduce aerosol source characteristics and to understand the atmospheric processes responsible for their generations and transformations - both horizontally and vertically in the Mediterranean urban environment. In order to achieve so, the unique approach of SAPUSS is the concurrent measurements of aerosols with multiple techniques occurring simultaneously in six monitoring sites around the city of Barcelona (NE Spain): a main road traffic site, two urban background sites, a regional background site and two urban tower sites (150 m and 545 m above sea level, 150 m and 80 m above ground, respectively). SAPUSS allows us to advance our knowledge sensibly of the atmospheric chemistry and physics of the urban Mediterranean environment. This is well achieved only because of both the three dimensional spatial scale and the high sampling time resolution used. During SAPUSS different meteorological regimes were encountered, including warm Saharan, cold Atlantic, wet European and stagnant regional ones. The different meteorology of such regimes is herein described. Additionally, we report the trends of the parameters regulated by air quality purposes (both gaseous and aerosol mass concentrations); and we also compare the six monitoring sites. High levels of traffic-related gaseous pollutants were measured at the urban ground level monitoring sites, whereas layers of tropospheric ozone were recorded at tower levels. Particularly, tower level night-time average ozone concentrations (80 +/- 25 mu g m(-3)) were up to double compared to ground level ones. The examination of the vertical profiles clearly shows the predominant influence of NOx on ozone concentrations, and a source of ozone aloft. Analysis of the particulate matter (PM) mass concentrations shows an enhancement of coarse particles (PM2.5-10) at the urban ground level (+64 %, average 11.7 mu g m(-3)) but of fine ones (PM1) at urban tower level (+28 %, average 14.4 mu g m(-3)). These results show complex dynamics of the size-resolved PM mass at both horizontal and vertical levels of the study area. Preliminary modelling findings reveal an underestimation of the fine accumulation aerosols. In summary, this paper lays the foundation of SAPUSS, an integrated study of relevance to many other similar urban Mediterranean coastal environment sites.

Propuesta sostenible para mitigar los efectos climáticos adversos en una ciudad costera de Argentina

Los indicadores de sostenibilidad climática constituyen herramientas fundamentales para complementar las políticas de ordenamiento del territorio urbano y pueden beneficiar la calidad de vida sus habitantes. En el presente trabajo se diseñó un indicador climático urbano para la ciudad de Bahía Blanca considerando variables meteorológicas y análisis de la percepción social. El mismo permitió delimitar la ciudad en cuatro regiones bien diferenciadas entre sí. A partir de entonces, se realizó una propuesta sostenible para mitigar los efectos adversos del clima a partir de la aplicación del método DPSIR. Las mismas estuvieron destinadas a mejorar las condiciones de vida de la población. Los resultados permitieron considerar que una pronta implementación de la misma junto con una activa participación de los actores sociales y los tomadores de decisiones es necesaria para mejorar las condiciones actuales en la que se encuentra la ciudad. Con las medidas propuestas, la población local sabrá cómo actuar ante la ocurrencia de distintos eventos extremos, eventos de desconfort climático, etc. Al ser un método sencillo, la metodología aplicada en este estudio puede replicarse en otras ciudades del mundo con el objetivo de mejorar la calidad de vida de los habitantes.

Coimbra: cidade amiga das pessoas idosas?!

Introdução: Em Portugal, bem como nos restantes países mundiais, tem sido registado, em virtude de múltiplas transformações societárias, um aumento crescente do envelhecimento demográfico. Este novo cenário demográfico originou uma reflexão, por parte de organizações supranacionais, sobre as cidades na sua relação com os munícipes mais velhos. Desta reflexão surge o projeto Cidade Amiga das Pessoas Idosas que apresenta referenciais de avaliação das cidades para que estas possam adaptar as suas estruturas e serviços aos seus munícipes mais velhos. Beneficiando desta forma do potencial que as pessoas mais velhas representam para a humanidade. Objetivos: O presente estudo tem como objetivo central verificar se a cidade de Coimbra é uma cidade amiga das pessoas idosas. Metodologia: A pesquisa remete para um estudo qualitativo exploratório a partir dos procedimentos metodológicos que constam do Protocolo de Vancouver. O focus group decorreu em duas sessões. Participantes: Foram auscultados 16 pessoas, 15 (93,8%) do sexo feminino. A idade média situa-se nos 79,88 anos (dp= ± 10,658), são maioritariamente viúvos (7= 43,8 %) e 7 (43,8%) e têm como habilitações a 4ª classe. Autoclassificam-se maioritariamente na classe média baixa (7 =43,8). Resultados: Das oito categorias analisadas três categorias “espaços exteriores e edifícios”, “transportes” e “respeito e inclusão social” são avaliadas com aspetos positivos e negativos. O “suporte comunitário e serviços de saúde” é avaliado como positivo enquanto a “habitação”, “participação social” e “comunicação e informação” são avaliados como negativos. As sugestões efetuadas referem-se a um único tópico “espaços exteriores e edifícios”. Conclusões: Se partilharmos a tese que uma cidade amiga das pessoas idosas estimula o envelhecimento ativo porque otimiza as oportunidades de participação no ambiente urbano melhorando, desta forma, a qualidade de vida das pessoas envelhecem. Os resultados que obtivemos, a partir da auscultação de um grupo de idosos, permitem-nos afirmar que Coimbra precisa de se adaptar aos seus munícipes mais velhos. Só assim Coimbra se poderá tornar uma cidade amiga das pessoas idosas. Importa igualmente registar que os resultados encontrados devem ser mediados pelo perfil sociodemográfico dos idosos entrevistados. / Introduction: In Portugal, as well as in other countries worldwide, has been registered by virtue of multiple associated transformations, an increasing growing of population. This new demographic scenario triggered, led to a reflection on the part of supranational organizations, about the cities in their relationship with the older residents. This reflection comes with the project Friendly City of Older Persons that presents benchmarks for the evaluation of cities so that they can adapt their structures and services to its older citizens. Enjoying this way the potential that older people represent for humanity. Objectives: This study aims to check if the city of Coimbra is an elderly friendly city. Methodology: The research refers to an exploratory qualitative study from the methodological procedures of the Vancouver Protocol. The focus group was held in two sessions. Participants: 16 people were sounded out, 15(93.8%) were female. The average ages tends at79.88 years (dp = ±10,658), are mostly widowers (7=43.8%) and 7 (43.8%) have the qualifications to4th grade. They are classified mostly in the lower middle class(7=43.8). Results: Of the eight analyzed categories three categories" outdoor spaces and buildings", "transport" and "respect and social inclusion" are evaluated on positive and negative aspects. The "community support and health services" is evaluated as positive as the"housing", "social participation "and "communication and information" are evaluated as negative. The suggestions are related to a single topic "buildings and outdoor areas." Conclusions: If we share the view that an elderly friendly citizen courages active aging because it optimizes the opportunities for participation in the urban environment improving, in this manner, the quality of life of the elderly. The results we obtained from the consultation of a group of elderly allow us to say that Coimbra needs to adapt to its older citizens. Only then Coimbra can become a friendly city of the elderly. It should also be noted that the results should be mediated by socio-demographic profile of elderly respondents.

Urbaania energiaa. Suvilahden, Hanasaaren A- ja Vuosaaren voimalaitokset osana helsinkiläistä kaupunkiympäristöä

Tutkimus koostuu kolmen Helsingissä sijaitsevan, kolmena eri aikakautena, 1910-, 1950- ja 1990-luvuilla, rakennetun voimalaitoksen arkkitehtuurista ja rakennustyypistä sekä niiden eroista ja erityisyyksistä samoin kuin näiden voimalaitosten roolista ja vaikutuksesta Helsingin kaupunkisuunnitteluun ja -rakentamiseen, kaupunkikuvaan sekä ympäristöestetiikkaan. Tutkimus on rajattu koskemaan erityyppisten voimalaitosten osalta yksinomaan kolmea helsinkiläistä kaupungissa sijaitsevaa voimalaitosta, Suvilahtea, Hanasaari-A:ta ja Vuosaaren A- ja B-laitoksia. Tutkimuksen tarkoituksena on ensinnäkin selvittää sekä periaatteessa että edellä mainittujen kolmen esimerkkikohteen kautta seikkoja, jotka ovat vaikuttaneet kunkin voimalaitoksen arkkitehtuuriin ja rakennustyyppiin kunakin aikakautena. Kaupunkivoimalan olennaiset elementit ovat korkea savupiippu, mittava polttoainevarasto sekä massiiviset rakennusmassat, jotka vaativat runsasta maankäyttöä. Toiseksi tutkimuksessa paneudutaan kaupunkisuunnitteluun laitoksen sijoittumisen osalta sekä ajallisesti että paikallisesti. Kolmanneksi selvitetään kaupunkikuvallisia ja ympäristöesteettisiä seikkoja, sekä niiden vaikutusten kehitystä voimalaitoksen toteutuksen ja nykyhetken kesken. Tutkimuksessa haetaan vastausta kysymykseen, miten Helsingissä sijaitseva voimalaitos arkkitehtuuriltaan, rakennustyypiltään ja sijoitukseltaan on soveltunut ja jatkossa soveltuu kaupunkisuunnittelun kannalta kaupunkikuvallisesti sekä ympäristöesteettisesti kyseiseen kaupunkiympäristöön. Tutkimus selvittää myös sitä ilmeistä ristiriitaa, joka syntyy kaupungin kehittyessä ja laajentuessa, jolloin voimalaitos infrastruktuurinsa ja useimmiten suunnattoman kokonsa vuoksi edustaa pysyvyyttä rakentuvan alueen sisällä. Tässä yhteydessä tutkimuksessa pohditaan esimerkkikohteiden avulla voimalaitoksen säilyttämistä puoltavia rakennustaiteellisia arvoja, mahdollista korvattavuutta, ja siinä yhteydessä haetaan vastauksia jäljelle jäävälle laitosrakennukselle kaupunkisuunnittelun kannalta asetettavista uusiokäytön vaatimuksista ja mahdollisuuksista. Tutkimuksen metodologia on sekä kvantitatiivisesti että kvalitatiivisesti historiallinen, esimerkkikohteita käsiteltäessä tarvittavassa määrin myös mikrohistoriallinen.
