Estudo sobre as condiÃÃes de sustentabilidade urbana nos espaÃos comuns em conjuntos habitacionais de interesse social em Fortaleza-CE / Study about sustainability conditions on urban spaces located in low income housing complexes from Fortaleza, Brazil

Sarah Bastos de Macedo Carneiro 16 August 2013 (has links)
FundaÃÃo Cearense de Apoio ao Desenvolvimento Cientifico e TecnolÃgico / Este trabalho tem como objetivo avaliar as condiÃÃes de sustentabilidade urbana nos espaÃos comuns em conjuntos habitacionais de interesse social (CHIS) localizados em Fortaleza-CE, atravÃs da anÃlise dos seus projetos de inserÃÃo urbana e implantaÃÃo. Os espaÃos comuns em CHIS correspondem aos espaÃos pÃblicos e semipÃblicos onde sÃo praticadas aÃÃes de convÃvio social, concentrando atividades e equipamentos de uso comum dos moradores. Segundo estudos, estes lugares sÃo fundamentais para promover a sustentabilidade urbana, atravÃs do fortalecimento de vÃnculos entre moradores e da integraÃÃo do conjunto com o restante da cidade, ao promover benefÃcios sociais. Em seus procedimentos metodolÃgicos, a pesquisa teve inÃcio com a revisÃo bibliogrÃfica em torno do uso dos espaÃos comuns em CHIS, assim como a inserÃÃo urbana e as condiÃÃes de implantaÃÃo. TambÃm foram abordadas as dimensÃes de desempenho estabelecidas por Lynch (2007) no livro \"A boa forma da cidade\", como a vitalidade, o sentido, a adequaÃÃo, o acesso e o controle, atuando como parÃmetro para a definiÃÃo de indÃcios de sustentabilidade em CHIS. A segunda etapa correspondeu à delimitaÃÃo do universo, utilizando como amostra quatorze CHIS produzidos pela FundaÃÃo de Desenvolvimento Habitacional de Fortaleza (Habitafor) para reassentamento de populaÃÃo de Ãreas de risco. Os elementos dos espaÃos comuns desses conjuntos foram levantados, organizados e caracterizados atravÃs da anÃlise documental dos projetos. Desta forma, foi possÃvel realizar a terceira etapa da pesquisa, que envolveu a anÃlise comparativa dos conjuntos, segundo os indÃcios de sustentabilidade levantados na revisÃo da literatura. A anÃlise permitiu a classificaÃÃo dos CHIS em quatro categorias: alta sustentabilidade, mÃdia sustentabilidade, baixa sustentabilidade e insustentabilidade, estimulando o cumprimento dos objetivos. Em suma, este trabalho pretende contribuir com a elaboraÃÃo de projetos urbanÃsticos de CHIS nos quais seus espaÃos comuns sejam elementos viabilizadores de sustentabilidade. / This study aims to evaluate the conditions of sustainability in urban spaces located in low income housing complexes from Fortaleza, Brazil. The analysis was done through these urban projects, by design documents. Collective spaces in low income housing complexes are public and semi-public places where residents practice social interaction. According studies, collective spaces are essential to promote urban sustainability because they stimulate social benefits. This research comprises three steps: First, a literature review about collective spaces in low income housing complexes, considering the urban insertion and the complex implantation, with emphasis on the five performance dimensions established by Lynch (2007) in his book "Good city form": vitality, sense, fit, access and control. These criteria were considered a parameter of sustainability in low income housing complexes. On the second step, were chosen fourteen housing complexes produced by the Housing Development Foundation from Fortaleza, known as "Habitafor". The elements of the collective spaces from these housing complexes were collected, organized and characterized through the analysis of their design documents. The third stepinvolved a comparative analysis of these collective spaces, considering their sustainability according Lynch's performance dimensions. The analysis rated the fourteen housing complexes in four categories: high sustainability, average sustainability, low sustainability and unsustainability, achieving the goal. Thus, this work aims to contribute for design process of urban projects which seek the sustai nability of collective spaces.

Ambiente urbano, qualidade de vida e (in)sustentabilidade em cidades locais : Nossa Senhora da Glória/SE

Jesus, Tânia Santos de 20 February 2006 (has links)
Being a built-up environment, the city involves the flow of immobilized capital in the space through physical equipments which are used in the production and consumption such as streets, buildings and sewer system. In the city, the natural environment can be transformed into residential, leisure, industrial and commercial areas. The appearance and/or expansion of cities without adequate planning, mainly relating to infrastructure can reflect in future problems that may interfere both in the quality of life of the inhabitants and in the environment quality. Due to the intense changes provoked by human action, the urban ecosystem has shown more and more distinct characteristics and working from the natural systems.The search for a new development standard in order to guarantee natural capital for future generations has brought to discussion the theme of sustainability. In this sense, the urban sustainability has been one of the biggest challenges of present time because of several environmental problems in the cities. This research is based on the rationale that the basic conditions in the city of Nossa Senhora da Glória/SE do not reveal a sustainable development and that public policies can lead to a perspective of reaching urban sustainability. The objective of this work is to analyse the different aspects of the development in Nossa Senhora da Glória/SE urban area, based on socioenvironmental indicators in attempt of identifying which factors can be interfering in the city sustainable development, as well as point to the main measures to be adopted in the field of public policies aiming at urban sustainability. The indicators considered were: solid wastes, basic sanitation, infrastructure, collective well-being, housing, public health, public education, work and income. It was adopted a methodology based on the concept of sustainability, using the following tools: bibliographical revision; fieldwork with photographic registers; interviews with the local inhabitants, and with public agencies and entities; application of questionnaires with the inhabitants; statistical treatment, analysis and discussion of the data collected. The intention of this work is to contribute to the adoption of a new attitude by local population and its governments relating to development. The use of socioenvironmental indicators constitutes a methodological approach that provides the comprehension of urban space processes. In this work, the use of this tool made possible the verification that socioespacial segregation analysed together with environment degradation specially in the outskirts, contributes to its weak degree of sustainability, influencing the inhabitants quality of life. / Por ser ambiente construído, a cidade envolve o fluxo de capital imobilizado no espaço através de equipamentos físicos utilizados para a produção e o consumo, a exemplo de ruas, edifícios, sistema de esgoto. Nela, o ambiente natural pode ser transformado em áreas residenciais, de lazer, industriais e de comércio. O surgimento e/ou expansão de cidades sem um adequado planejamento, principalmente no que se refere à infra-estrutura pode refletir em problemas futuros, podendo interferir tanto na qualidade de vida dos moradores, quanto na qualidade ambiental. Devido às intensas mudanças provocadas pela ação humana no ecossistema urbano, este apresenta características e funcionamento cada vez mais distintos dos sistemas naturais. A busca por um novo padrão de desenvolvimento visando a garantia de capital natural para as futuras gerações trouxe à discussão o tema da sustentabilidade. Nesse sentido, a sustentabilidade urbana tem constituído num dos maiores desafios da atualidade, em virtude dos diversos problemas ambientais verificados nas cidades. Essa pesquisa baseia-se no pressuposto de que as condições básicas na cidade de Nossa Senhora da Glória/SE não revelam um desenvolvimento sustentável e que as políticas públicas podem contribuir neste sentido à reorientação na perspectiva da sustentabilidade urbana. Objetivou-se neste trabalho analisar os diferentes aspectos do desenvolvimento na área urbana de Nossa Senhora da Glória/SE, com base em indicadores socioambientais em busca dos fatores que podem estar interferindo na sustentabilidade do desenvolvimento da cidade, bem como relacionar as principais medidas a serem adotadas no campo das políticas públicas rumo à sustentabilidade urbana. Os indicadores para este estudo foram: resíduos sólidos, saneamento básico, infra-estrutura, bem-estar coletivo, habitação, saúde pública, educação pública, trabalho e renda. Foi adotada uma metodologia com base no conceito de indicadores de sustentabilidade, utilizando as seguintes ferramentas: revisão bibliográfica; trabalho de campo com registros fotográficos; entrevistas junto à população local, órgãos e entidades públicas; aplicação de questionários aos moradores; tratamento estatístico, análise e discussão dos dados obtidos. Pretende-se contribuir com o presente trabalho na adoção de uma nova postura por parte da população local e seus governantes com relação ao desenvolvimento. A utilização de indicadores socioambientais constitui uma abordagem metodológica que propicia a compreensão dos processos espaciais urbanos, neste trabalho o uso desta ferramenta possibilitou a constatação de que a segregação socioespacial analisada enquanto indissociável da degradação do meio ambiente verificada principalmente na periferia da cidade contribui para o seu fraco grau de sustentabilidade, influenciando na qualidade de vida dos seus moradores.

A sustentabilidade na RMSP através do saneamento básico: Sabesp, um estudo de caso / The sustainability of RMSP through the sewerage system: Sabesp, object of study

Marcelo Teixeira 27 August 2010 (has links)
O trabalho consiste em entender o papel de uma empresa de saneamento, a Sabesp, Companhia de Saneamento Básico de São Paulo, na sustentabilidade da Região Metropolitana de São Paulo, RMSP, através de seus projetos estruturantes: Projeto Tietê, Projeto Vida Nova, Córrego Limpo e o PURA. Para tanto, foram analisados os dados oficiais dos programas desenvolvidos pela companhia paulista juntamente com depoimentos dos profissionais envolvidos com os projetos, com especialista do Instituto de Pesquisas Tecnológicas - IPT e do responsável pelo Programa Vida Nova da PMSP. A partir de então, pôde-se concluir que, apesar do bom encaminhamento dos programas e de suas ações serem multidisciplinares, é necessário que, para que se tenha um resultado efetivo, todas as ações sejam pensadas e desenvolvidas de forma ampla e sistemática, com participação intensa e colaborativa de toda a sociedade bem como de agentes públicos e privados e em longo prazo. / The work consists in understanding the role of a sanitation company, Sabesp, the Basic Sanitation Company of São Paulo, at the sustainability of São Paulo´s Metropolitan Region (RMSP), by means of its structuring projects: Projeto Tietê, Projeto Vida Nova, Córrego Limpo and PURA. In order to do that, the official data of the developed programs by the São Paulo´s company have been analyzed, together with the statements of the professionals involved with the projects, with the expert of the Instituto de Pesquisa Tecnológica - IPT and the responsible for the Programa Vida Nova of São Paulo´s City Hall. From then on, it was possible to conclude that, despite the good management of the programs and that their actions are multitasks, it is necessary that, in order to achieve an effective result, all actions are reasoned and developed in a broad and systematic way, with an intense and collaborative participation of all society as well as the public and private players and in the long term.

Paisagem e sustentabilidade urbana: o papel dos loteamentos fechados e condomínios horizontais em Vinhedo - SP / Landscape and urban sustainability: the role of gated communities in Vinhedo - SP

Francisco de Assis Gonçalves Junior 19 December 2014 (has links)
A partir de questionamentos associados à proliferação de condomínios horizontais e loteamentos fechados em Vinhedo (gated communities nos E.U.A), procurou-se evidenciar através de indicadores pautados no conceito de sustentabilidade urbana, o que se tem de realmente sustentável quando da introdução destes empreendimentos na paisagem. Para isso foram consideradas duas dimensões: a sustentabilidade social urbana e a sustentabilidade ambiental urbana, cada qual com dois indicadores; mobilidade e acessibilidade a áreas verdes ou/lazer públicas intramuros, cobertura vegetal arbórea e impermeabilização dos solos, sendo estes últimos analisados entre 1962 e 2012, tanto intra como extramuros. Esta proposta visou demonstrar que o modelo ou padrão de habitação urbana baseada em loteamentos fechados e condomínios horizontais amplia em Vinhedo a possibilidade de alcance da sustentabilidade ambiental urbana, ao mesmo tempo em que reduz a possibilidade de alcance da sustentabilidade social urbana, uma vez que sua lógica de implantação desconsidera importantes funções sociais a serem desempenhadas pela cidade, dessa forma, o alcance da sustentabilidade urbana considerada como um todo se torna parcial. / From questions associated with the proliferation of horizontal condominiums and closed subdivisions in Vinhedo (gated communities), it was tried to highlight by indicators guided the concept of urban sustainability, which has really sustainable when the introduction of these enterprises in the landscape. For this we considered two dimensions: urban social sustainability and urban environmental sustainability, each with two indicators; mobility and accessibility to green areas or / public recreational intramural, arboreal coverage and soil sealing, the latter being analyzed between 1962 and 2012, both intra and extramural. This proposal aimed to demonstrate that the model or pattern of urban housing based on closed subdivisions and horizontal condominiums in Vinhedo expands the possibility of reach of urban environmental sustainability, while reducing the possibility of reaching the urban social sustainability, once its logic implementation ignores important social functions to be performed by the city, thereby achieving urban sustainability considered as a whole becomes partial.

No. of bitstreams: 1 camillelanzarottinolasco.pdf: 4231521 bytes, checksum: 9bd719e28ed8fb0e1159fe2d22409fce (MD5) Previous issue date: 2009-09-09 / A Agricultura Urbana (AU) tem sido objeto de estudos recentes, devido à sua grande importância junto às ciências sociais e políticas e sua localização dentro dos limites das cidades contemporâneas. Suas implicações na Ecologia Urbana vão desde a manutenção de áreas verdes e interação com a fauna, até a perpetuação de saberes tradicionais da população, passando por questões como a segurança alimentar de seus habitantes, a utilização dos recursos naturais, e a sustentabilidade urbana. Entender como a Agricultura Urbana está inserida na Ecologia Urbana permite criar propostas integradas a outras questões de cunho ecológico que venham a direcionar a cidade para um futuro sustentável. O presente estudo teve como objetivo central compreender a dimensão ecológica da agricultura urbana, nas áreas intra e periurbanas, do Distrito Sede do município de Juiz de Fora, Estado de Minas Gerais, Brasil, analisando como a prática da agricultura urbana dialoga com a ecologia desta cidade. Através das indicações de informantes foram encontradas 179 áreas de ocorrência de AU em Juiz de Fora, separadas em setores específicos na execução desta pesquisa: Projetos Sociais Municipais, Escolas (municipais, estaduais, federais e particulares), Instituições (públicas, religiosas, assistenciais e unidades básicas de saúde), Áreas de Produção Comercial, e Quintais Produtivos (no bairro Monte Castelo). Entrevistas semi-estruturadas e visitas foram realizadas em um total de 77 áreas. A partir do resultado obtido empiricamente, foi possível categorizar os agricultores urbanos de Juiz de Fora (migrantes rurais, idosos, professores, alunos, beneficiários de projetos e agricultores comerciais) que associaram a atividade agrícola a uma melhoria na qualidade de vida, apresentando orgulho de suas produções, felicidade e apreciação da beleza cênica. Constatou-se que as interações ecológicas se dão de várias formas, sendo encontrados pontos positivos como o menor deslocamento entre a produção e o consumidor final, a manutenção e criação de áreas verdes e com solo permeável, a pouca utilização de agrotóxicos, o fornecimento de alimento e habitat para indivíduos da fauna, a diversidade de espécimes vegetais, o aproveitamento de resíduos orgânicos através de compostagem (pouca ainda), a aproximação das pessoas com o verde e a utilização da AU como ferramenta de educação ambiental, alimentar e cidadã. Dentre os pontos negativos levantados estão: a utilização de águas contaminadas, a utilização de alguns agrotóxicos e de adubação química, e o pouco aproveitamento dos resíduos orgânicos. Sendo que a maioria dos problemas relacionados com a má utilização dos recursos naturais pelos agricultores urbanos se deve a falta de instrução, treinamento e acompanhamento. A pesquisa constatou que as áreas agrícolas urbanas em Juiz de Fora constituem locais de grande importância para os envolvidos, para a conservação dos recursos naturais e biodiversidade, para a manutenção de saberes tradicionais e são fundamentais na busca por uma sustentabilidade desta cidade. / The urban agriculture (UA) has been the object of recent studies due to its importance from the social and policy sciences and its location within the limits of contemporary cities. Their implications for Urban Ecology ranging from the maintenance of green areas and interaction with wildlife, to the perpetuation of traditional knowledge of the population, through such issues as, food security of its inhabitants, use of natural resources and urban sustainability. Understanding how Urban Agriculture is embedded in the Urban Ecology, create integrated proposals to other environmental issues that will guide the city into a sustainable future. This study aimed to understand the ecological dimension of the Urban Agriculture, within urban and in suburban areas of the District Headquarters of the municipality of Juiz de Fora, Minas Gerais, Brazil, analyzing how the practice of Urban Agriculture occurs and argue with the ecology of this city. Were found 179 areas of UA occurrence in Juiz de Fora indicated by the informants, separated into specific sectors in the implementation of this research: Social Municipal Projects, Schools (municipal, state, federal and private), Institutions (public, religious, welfare and basic health units), Commercial production areas, and Productive backyards (neighborhood of Monte Castelo). Semi-structured interviews and visits were carried out in a total of 77 areas. From the empirical result, it was possible to categorize the urban farmers of Juiz de Fora (rural migrants, elderly, teachers, students, beneficiaries of projects and commercial farmers) who joined the agricultural activity to an improvement in quality of life, having pride of their productions, happiness and appreciation of scenic beauty. The ecological interactions occur in several ways, being observed positive points as the smaller distance between production and final consumer, the maintenance and creation of green areas and permeable soil, low use of agrochemicals, supply of food and habitat for fauna individuals, diversity of plant specimens, use of organic waste through composting (still low), the approach of people with the green and use of the UA as a tool for food, citizen and environmental education. Among the negative points raised are: the use of contaminated water, the use of some pesticides and chemical fertilizer, and little use of organic waste. The majority of problems related to bad use of natural resources by farmers are due to lack of education, training and monitoring. This research found that urban agricultural areas in Juiz de Fora are places of great importance for those involved, for the conservation of natural resources and biodiversity, for the maintenance of traditional knowledge, and are fundamental in the search for sustainability of this city.

Avaliação da sustentabilidade ambiental, econômica e social em telhados verdes : estudo de caso entre Brasil e Portugal /

Rocha, Rosane January 2020 (has links)
Orientador: Rosane Aparecida Gomes Battistelle / Resumo: O cenário mundial apresentado na atualidade constata que a população migra cada vez mais para áreas urbanas, com estimativa de que, em 2050, 66% da população mundial deverá estar na zona urbana. As consequências negativas ambientais ficam cada vez mais evidentes, mas por outro lado tem surgido alternativas com maior responsabilidade ambiental, como forma de evitar maiores desastres e danos ao meio ambiente e contribuindo para a sustentabilidade do planeta. Uma dessas alternativas são os telhados que são responsáveis por 40% a 50% da área de superfície urbana impermeável, e que podem contribuir com os benefícios ambientais, econômicos e sociais. Nesse sentido, o presente trabalho teve o objetivo de identificar vantagens e desvantagens dos telhados verdes. Para cumprir com esse objetivo, o trabalho efetuou dois estudos de caso em telhados verdes de países distintos, comparando-os sob o viés da sustentabilidade, compilou todas as vantagens e as desvantagens encontradas na literatura e identificou alternativas de materiais mais sustentáveis na composição das camadas de uma cobertura verde. Como vantagens gerais, foram encontradas a mitigação das ilhas de calor urbana, gerenciamento de águas pluviais, eficiência energética, minimização de gases de efeito estufa, maximização da biodiversidade, durabilidade do telhado, mitigação da poluição do ar e da poluição sonora, agricultura urbana, conforto térmico, desenvolvimento social e estética. Como desvantagens gerais, os custos, falta ...

The negative environmental consequences are becoming more frequently evident and so we see more alternatives that show greater environmental responsibility as a way to prevent greater disasters and damage to the environment and contributing to the sustainability of the planet. As roofs are responsible for 40% to 50% of the impermeable urban surface area, they provide the option of planting vegetation and they are a way to obtain environmental, economic and social benefits. With this in mind, the present work aimed to identify advantages and disadvantages of green roofs. To fulfill this objective, the work carried out two case studies on green roofs from different countries, comparing them with a sustainability mindset, compiled all the advantages and disadvantages found in the literature and identified more sustainable material alternatives for the composition of the layers in a green roof. As general advantages, we have spotted the mitigation of urban heat islands, rainwater management, energy efficiency, minimization of greenhouse gases, maximization of biodiversity, roof durability, mitigation of air and noise pollution, urban agriculture, thermal comfort, social and aesthetic development. The general disadvantages are the costs, lack of government incentives, technical difficulties in the design pr... (Complete abstract click electronic access below) / Mestre

Everyday Urbanism, An Alternate Approach to Urban Public Space : Promoting Sustainable Lifestyles in Chennai, India

Ramachandran, Arvind January 2012 (has links)
Privatization of the public realm is rampant in modern cities. Public space accessibility and usage is often determined by inhabitants’ socio-economic background in the mega cities of the developing world as well. The case of Chennai, a city of 9 million people drawn from different regions in India, is used in this project to understand this phenomenon and evolve an alternate approach to urban public space design and use, in which citizen-led initiatives are encouraged, instead of being ignored, by mainstream urban planning and design processes. Chennai is one of the fastest growing cities in the world today. Conventional planning has failed to direct this growth towards creating sustainable urban environments for all, and has instead encouraged lopsided development that caters only to the affluent sections. This trend has affected public spaces as well, which are now centered on consumption and dependant on heavy investment in real estate and technology. This has a considerable impact on the spectrum of socio-economic groups that are able to access and use them. The project questions the prevalent situation, and focuses on three aspects that have been ignored in recent times. The first (Everyday Urbanism) is explored as a method to revitalize the second (Public Spaces), in order to achieve the third (Sustainable Lifestyles) as a long term goal. This is done using analysis and design in parallel, and results in a proposal for a new design process and through it, scale specific design solutions for Chennai’s public spaces that will create a high quality of life for inhabitants of the heavily populated, demographically diverse and socio-economically fragmented city.

Urban Mining in Malmö - An Investigative Study to Identify the Potential of Urban Mining

Anesie, Laura Noemi January 2018 (has links)
This master thesis depicts the topic of urban mining and its possibilities and challenges in the city of Malmö. Because of present day’s high consumption and construction our resources are becoming scarcer. In order to continue to build and consume the way we do, we need to look at other alternatives to obtain these resources. One sustainable alternative is urban mining which is based on society as a resource base where material accumulating over time is a metal storage that can be used through reuse or recycling. This thesis is limited to one type of urban mining which refers to unused cables and pipes that lie underground, so called hibernating cables. The purpose of this thesis is to explore the possibilities and challenges with urban mining in the city of Malmö and to research the Kabel-x urban mining method and its implementation possibilities. To successfully understand the challenges and possibilities a qualitative approach was taken where semi-structured interviews were conducted to see attitudes towards urban mining as well as to identify stakeholders who would work with an urban mining project in the future. The qualitative approach was complemented by a literary research which built the theoretical framework with theories like urban mining, urban metabolism and material flow analysis and sustainability assessments. The empirical discoveries depict topics such as ownership, knowledge-gap or skepticism when it comes to urban mining as well as methods of extractions, but also point to high interest and economic incentives with are in concordance with sustainability aspects. This lead to the conclusion that urban mining shows both possibilities and challenges in Malmö, which proves a challenging but worth implementation. Regarding Kabel-x method, its sustainability aspects and challenges with its implementation, it was concluded that on account of mostly skepticism and knowledge-gap stakeholders proved its implementation challenging but also interesting for urban development.

Influence of Energy Benchmarking Policies on the Energy Performance of Existing Buildings

Hamad, Samar 01 January 2018 (has links)
Energy benchmarking and disclosure policies exist in several local and state governments to manage the energy consumption of existing buildings and encourage energy efficient retrofits and upgrades, yet little is known about whether these efforts have improved overall energy efficiency. The purpose of this repeated-measures study was to examine the influence of New York City's (NYC's) Benchmarking Law (LL84) on the energy performance of the city's existing commercial buildings through investigating whether the energy performance of the city's existing commercial buildings significantly improved after the implementation of this policy. The study was based on Ostrom's institutional analysis and development framework. Paired-sample t tests were performed to statistically analyze the annually disclosed energy benchmarking data for 1,072 of NYC's existing commercial buildings that were benchmarked in both 2011 and 2016. Compared to 2011, the study results revealed statistically significant improvements in the energy performance of NYC's commercial buildings by 2016. On average, their site energy use intensity (EUI) significantly reduced by 5%, source EUI significantly decreased by 10%, greenhouse gas emissions significantly dropped by 12%, and ENERGY STAR performance rating significantly improved by 5%. However, these improvements were primarily achieved in 2012, 1 year after the city's energy benchmarking data were publicly disclosed. Additional measures should be considered to maintain continuous energy savings and greenhouse gas mitigation patterns. Positive social change implications include the potential to promote energy-efficient upgrades and inspire the adoption of sustainable building concepts.

Compromise or Preserve the Green Characteristics? : Densification and green spaces in Eriksberg, and the impact on residents’ well-being

Balasingam, Melanie January 2024 (has links)
As Uppsala’s population is in constant growth, Uppsala Municipality has designed a plan to densify Eriksberg and provide more residential homes, while localizing facilities for essential services and social infrastructure (Uppsala kommun, 2017:4). This will affect various green spaces in Eriksberg, which are an important part of the district and have long characterized the area (Lagergren et al., 2015:17; Uppsala kommun, 2017:19-32). Ample research suggests that green spaces offer various benefits to well-being, therefore, this study aims to analyze the effects of urban densification on green spaces in Eriksberg, with a focus on well-being (Kim et al., 2023:2; Coombes, E. et al., 2010; Guttman et al., 2021:2; Apkinar, 2016:76; Lee et al., 2015:132). The chosen method is a content analysis, consisting of a document analysis and a news media analysis. The results of the study illustrate that both the psychological and physical well-being of Eriksberg’s residents could, in several ways, be impacted by Uppsala Municipality’s development plans and efforts to densify the district. Moreover, many Eriksberg residents are concerned with green spaces being replaced or compromised in the development process, which the development plans suggest will happen in certain areas. However, the municipality has made some efforts to take residents’ opinions into consideration and, in certain instances, adhere to their wishes.
