Medidas não-estruturais na prevenção de enchentes em bacias urbanas: cenários para a bacia do Gregório, São Carlos - SP / Non-structural measures on prevention of floods in urban basins: scenarios for Gregório river watershedElisânia Magalhães Alves 02 August 2005 (has links)
O presente estudo aborda a questão da drenagem urbana, enfocando a interdependência entre planejamento do uso do solo e do sistema de drenagem para o controle das enchentes. Considera que o sistema de drenagem, no planejamento de uma bacia urbana sustentável, deve ser previsto na fase inicial do planejamento urbano e integrado aos demais planos de desenvolvimento, para que atue de maneira preventiva, o que depende de conhecimento prévio do funcionamento do sistema urbano e da capacidade de previsão de possíveis alterações ambientais. É enfatizada a adoção de medidas não-estruturais no controle e prevenção de inundações e a definição de critérios ambientais para guiar o processo de ocupação urbana, a partir da identificação das vulnerabilidades e limitações de uso impostas pelas características naturais do meio. Dentro dessa nova abordagem de drenagem urbana, é apresentado um estudo de caso onde se avalia o efeito das medidas não-estruturais em micro-bacia parcialmente urbanizada. São propostos oito cenários do uso e ocupação do solo, em situações no passado, presente e futuro, com e sem medidas não-estruturais. A análise dos resultados das simulações hidrológicas dos cenários indica que medidas não-estruturais, quando adotadas em conjunto, resultam em percentual significativo de áreas permeáveis e são eficientes no controle do escoamento superficial e na atenuação de vazões de pico. / This work treats urban drainage issue in respect to the interdependence between urban planning and drainage system in order to control floods. The drainage system planning must be considered in the beginning of the urban planning and integrated to other plans, acting in a preventive way. A previous knowledge of the environmental factors in order to predict the negative impacts in the future is necessary in this planning approach. It is emphasized the adoption of non-structural measures in order to control and prevent urban floods and also the choice of environmental criteria to conduct the urban development, given the potential and constraints of the land. Inside this new approach of urban drainage, one study case in a micro watershed is presented, where non-structural measures are applied and evaluated. The land use scenarios are simulated in rainfall-runoff model and then evaluated. Hydrologic simulation results point that non structural flood control measures, when they are adopted together, result in an expressive percentage of pervious areas. Also, they are efficient in controlling run-off and peak discharges attenuation.

AGRI-CULTURA URBANA : Sharing hubs of transition in Cortijo de Cuarto in Seville, Spain.Pulvino, Sharon January 2017 (has links)
The modern dichotomy between the urban and the rural is increasingly affected by the superimposition of urbanisation processes on the rural landscape, usually contributing to the disappearance of the agricultural heritage. Thanks to a high degree of awareness towards the necessity of natural capitals in human life, today the interdependence between man and nature is progressively becoming of fundamental importance. Contemporary issues related to urban overgrowth, food supply and depletion of material resources increase the necessity for urban planning processes in rural areas to apply principles of integration with the existing context. It becomes the role of contemporary urban planners to carefully manage the natural capital and develop urban sustainable strategies to fulfill human needs in the respect of the eco-system.Particularly, this thesis investigates the controversial relationship between the urban and the rural in the case study of Cortijo de Cuarto in Seville, rural area in the southern suburb of the Spanish city currently subjected to traditional urbanisation processes of urban sprawling.The focus will be to highlight the potentiality of this land as agricultural heritage and propose a development strategy based on three hubs of transition from the urban to the rural landscape, looking at the features of the local context toward the preservation and valorisation of its identity. Therefore, AgriI-Cultura Urbana stands out as an urban development program that looks at agriculture as a landscape experience from a social, economic and environmental point of view, enhancing a culture of integration between local agricultural activities and urbanisation programs, taking into consideration the benefits of both citizens and the environment.

Mobilidade urbana sustentável e o caso de Curitiba / Sustainable urban mobility and the case of CuritibaMiranda, Hellem de Freitas 13 October 2010 (has links)
O atual modelo de planejamento dos transportes é constantemente confrontado com novos ideais associados à mobilidade sustentável. Assim, inúmeros pesquisadores debruçam-se em busca de indicadores e índices capazes de avaliar e monitorar o desempenho de políticas públicas relacionadas ao tema. Dessa forma foi desenvolvido o Índice de Mobilidade Urbana Sustentável (IMUS), uma ferramenta pautada nos preceitos da mobilidade sustentável com a proposta de tornar-se um apoio à gestão municipal. Por ser um método recente, sua aplicação ainda é limitada. Assim, o objetivo deste estudo concentra-se em realizar o cálculo do índice na cidade de Curitiba, muito conhecida por suas soluções urbanas que associam o planejamento dos transportes ao uso do solo. A aplicação do método na cidade fundamentou-se não apenas em obter o simples score relacionado ao desempenho das condições da mobilidade local, mas também possibilitaram avaliar o próprio método. O valor resultante alcançado foi correspondente a 0,747, confirmando Curitiba como uma cidade com características bastante positivas quanto às políticas urbanas voltadas à mobilidade. Por outro lado, foram identificadas algumas deficiências, especialmente quanto aos modos não motorizados de transporte. O cálculo do IMUS permitiu encontrar também indicadores que não foram capazes de identificar aspectos reconhecidamente favoráveis da cidade, demonstrando que possivelmente esses apresentem problemas de avaliação ou normalização de valores. A aplicação do método também se mostrou eficiente para promover uma avaliação intraurbana entre as diversas regiões da cidade. Nesse aspecto Curitiba demonstrou um saudável equilíbrio, sem apresentar grandes disparidades quanto suas políticas locais. Tal característica mostra-se bastante favorável para identificar Curitiba como um benchmarking da mobilidade sustentável. Finalmente o método foi testado como uma ferramenta de comparação entre cidades distintas, demonstrando também ser eficiente, desde que se mantenha uma estrutura de cálculo compatível entre as cidades que se deseja comparar. / The current transportation planning approach is constantly confronted with new values derived from the concept of sustainable mobility. As a consequence, several researchers have devoted time and effort in the search of indicators and indexes capable of evaluating and monitoring the performance of urban policies related to the theme. The Sustainable Urban Mobility Index (I_SUM) was one of them. It is a decision support tool developed to help municipal administrations in the planning and management of sustainable mobility. As it is a recent method, its application is still limited to just a few cases. The objective of this study is to conduct an application of the index in Curitiba, which is a well-known city due to the quality of its urban planning solutions that associate transport planning to land use. The application of the method in the city was motivated not only by the possibility of having a score showing the performance of the city regarding sustainable mobility, but also by the opportunity of evaluating the method itself. The overall resulting value was 0.747, what confirms that Curitiba has very positive characteristics and effective urban policies regarding sustainable mobility. Conversely, some deficiencies were identified, especially concerning non-motorized transport modes. The I_SUM calculation also allowed the identification of indicators that were not able to identify aspects that are good to the city. That may suggest problems in the assessment or normalization procedures of the index. The method application was also efficient for the evaluation of city subdivisions. Curitiba also performed well in that intra-urban evaluation, with a positive equilibrium of the values throughout the city. It may be an indication that the city policies are homogeneously applied in the entire urban area, what certainly contributes to characterize Curitiba as a benchmark of urban mobility. Finally, when used to compare distinct cities, the method was also efficient. In that case, the calculation was compatible with a structure adjusted to simultaneously represent the compared cities.

Um índice de mobilidade urbana sustentável / An index of sustainable urban mobilityMarcela da Silva Costa 08 October 2008 (has links)
Esta pesquisa tem como objetivos: identificar os conceitos que estruturam o referencial de mobilidade urbana sustentável, desenvolver uma ferramenta para diagnóstico e monitoração da mobilidade urbana e realizar a sua avaliação a partir de uma aplicação em uma cidade de médio porte. O processo de construção do referencial de mobilidade urbana sustentável, feito a partir de workshops realizados em onze cidades brasileiras através da metodologia multicritério de apoio à decisão construtivista (MCDA-C), revelou questões-chave que devem ser consideradas para a implementação do conceito. Ao mesmo tempo, forneceu as bases para a construção da ferramenta denominada de índice de mobilidade urbana sustentável - IMUS. O índice é constituído de uma hierarquia de critérios que agrega nove domínios, trinta e sete temas e oitenta e sete indicadores. Seu sistema de pesos permite identificar a importância relativa de cada critério de forma global e para cada dimensão da sustentabilidade (social, econômica e ambiental). Seu método de agregação permite a compensação entre critérios bons e ruins. O índice apresenta ainda escalas de avaliação para cada indicador, permitindo verificar o desempenho em relação a metas pré-estabelecidas e realizar análises comparativas entre diferentes regiões geográficas. A aplicação do IMUS para a cidade de São Carlos, estado de São Paulo, indicou a viabilidade de sua utilização para a monitoração da mobilidade e avaliação de impactos de políticas públicas em cidades de médio porte, e revelou aspectos importantes sobre as condições de mobilidade no município. O resultado global do IMUS para a cidade alcançou valor em torno de 0,58, considerado médio segundo a escala de avaliação proposta para o índice. A aplicação do índice permitiu identificar fatores críticos e fatores de maior impacto para a melhoria de aspectos globais e setoriais da mobilidade urbana, fornecendo subsídios para a proposição de políticas e estratégias visando melhorar a mobilidade urbana sustentável. A compatibilidade dos resultados obtidos segundo o cálculo dos indicadores e análise expedita feita por um especialista sugere que o IMUS fornece resultados confiáveis para o acompanhamento das condições de mobilidade urbana em cidades e médio e grande porte. / The objectives of this research are: (i) to identify the concepts that shape the sustainable urban mobility framework; (ii) to develop a tool for assessing and monitoring urban mobility conditions; and (iii) to evaluate the proposed tool through an actual application in a medium-sized city. The main elements of the sustainable urban mobility framework were identified in workshops conducted in eleven brazilian cities. The use of a multicriteria decision analysis-constructivist (MCDA-C) approach in the workshops revealed key elements that shall be considered in the concept implementation. In addition, it provided the basic elements for the development of the so-called index of sustainable urban mobility - I_SUM. The index is formed by a hierarchy of criteria with nine domains, thirty-seven themes, and eighty-seven Indicators. The weighting system makes it possible to identify the relative importance of each criterion for the global Index as well as for each sustainability dimension (social, economic, and environmental). Furthermore, the aggregation procedure adopted allows for trade-offs, therefore compensating good and bad performances found among the indicators. The index is also associated with evaluation procedures for each Indicator, which makes it possible to compare index values with predefined goals and to carry out comparative analyses between different geographic regions. The application of I_SUM to São Carlos, a city in the state of São Paulo, has shown the feasibility of its use to monitor local mobility conditions and to evaluate impacts of public policies in medium-sized cities, revealing important mobility aspects in the city. The global I_SUM value for the city was 0.58, what can be considered a reasonable value when compared with the reference values proposed for the index. The use of the index highlighted critical factors and those that have significant impact on the global and certain dimensions of urban mobility. These inputs might be useful for the formulation of policies and strategies aiming at achieving greater sustainable urban mobility. Lastly, the comparison between the value obtained with the index calculation procedures and that estimated by an expert suggests that I_SUM can give reliable estimates of mobility conditions in medium and large-sized cities.

La campagne "Fair Trade Towns" : une mise en territoires du commerce équitable au nom du développement durable : exemples de Lyon et Bruxelles-Capitale / The “Fair Trade Towns” campaign : territories for fair trade in the name of sustainable development : Lyon, BrusselsRolland, Lisa 04 December 2015 (has links)
Le commerce équitable fait majoritairement l’objet de travaux en sciences agro-économiques (études d’impact, de filière, structuration des organisations,…). Par ailleurs, si les premières recherches étaient centrées vers le Sud et dans la compréhension de flux mondialisés, un décentrement du secteur vers d’autres espaces et dynamiques d’acteurs est perceptible autour de nouveaux enjeux liés à son inscription dans les politiques publiques. Cette évolution ouvre des perspectives originales de recherche et élargit le champ des disciplines concernées. La thèse s’inscrit dans ces nouvelles approches. Elle interroge les « Fair Trade Towns », campagne internationale de promotion du commerce équitable lancée en 2000, déclinée essentiellement dans les villes européennes. Dans ce projet l’objectif est d’associer collectivités, acteurs locaux, privés et publics, pour valoriser le commerce équitable à l’échelle d’un «territoire». Dans une démarche de géographie sociale, la recherche s’intéresse à ce changement de paradigme du commerce équitable et interroge le rôle de nouveaux acteurs dans ce processus ainsi que les différentes strates spatiales en jeu dans le cadre d’une territorialisation inédite. Pour les comprendre, la thèse se fonde sur des enquêtes de terrain associant entretiens, dessins (cartes mentales) et observation. Les villes de Lyon et Bruxelles sont les deux terrains d’étude choisis : déclinée nationalement « Territoires de commerce équitable » en France (2009), « Communes du commerce équitable » ou « Fair Trade Gemeente » en Belgique (2004), la campagne prend la forme d’un titre décerné à une collectivité, mais aussi celle d’un outil de communication du développement durable urbain. La campagne atteste du rôle nouveau et central de collectivités dans ce projet territorial, avec des stratégies d’acteurs et des tensions palpables sur une redéfinition du commerce équitable dans les Nords. / Fair trade is principally the object of study in agro-economical research (case studies on fair trade impact, networks, structuring of organisations…). Moreover, even if initial research was centred on the South and on the understanding of globalized flows, a growing shift towards the North appears with its integration into sustainable public policy. This progression leads to new research perspectives and broadens the subjects. This thesis falls within these new approaches. It questions fair trade geography with a special focus on the international campaign “Fair Trade Towns”, launched in 2000 to promote fair trade and which is centred mainly on European cities. In this project, the goal is to promote faire trade by linking communities with local private and public actors at a new scale for fair trade which mainly takes “towns” into consideration rather than cities. Within social geography, this research focuses on the paradigm change of fair trade and questions the role of new actors in this process, as well as the different scalar levels involved in a new territorialisation. To analyse and understand them, this thesis is based on field studies which combine interviews, drawing (mental maps) and observation. The two case studies chosen are the cities of Lyon (France) and Brussels (Belgium): on a national level “Fair Trade Territories” in France (2009), “Fair Trade Communities” or “Fair Trade Gemeente” in Belgium (2004), the campaign takes the form of a title given to a community, but also the one of an urban sustainable development communication tool. The campaign testifies of the new and central role played by communities in this territorial project, including stakeholder strategies and noticeable tensions concerning the redefinition of fair trade in the North.

Previous issue date: 2005-09-30 / Universidade Federal de Minas Gerais / This work inserts in the debate of the sustainable local development, specifically about the formularization of the public politics of social habitation that generate changes of regional development and participation of agents in the production of public proposals. It considered the scales of performance of a public politic and the spheres that it participates. With the objective to identify the difficult of this process we were adopted a strategy of research an only case in a small city. In Itararé, located in the southwestern region of São Paulo state, with experience to formulate public politics of social habitation with regional development, there is a project "Social Habitation in Economic Wood as Alternative for Multiple Uses of the Forest". This case permits us understand the different performance by the social agents during the process to elaborate lines of direction of public politics. It was distinguishes differet citizens like analytic categories (representative of the administration, the organized society, private initiative, researchers and others like owner of carpenters or sawmills) and the way like them participation in this process. The revision of literature, the systematization of data, the direct comment and interviews, evidenced the difficult of a small city to elaborate its proper public politics. Such limits are associates the diverse factors related to the agents who compose the project: public administration, local population, private initiative, universities and other partners. From the analysis of the participation of these actors in Itararé s experience, we give an important conclusion: it did not have the sufficient interaction between the public administratio, the productive sector, the organized population and the assessorship technique, so that the project in this city was consolidated. / Este trabalho se insere no debate do desenvolvimento local sustentável, especificamente na formulação de políticas públicas de habitação social que gerem oportunidades de
desenvolvimento regional e participação de agentes na produção de propostas públicas. Considerou-se neste debate as escalas de atuação de uma política pública e as esferas que
dela participam. Com o objetivo de identificar os limites no processo de formulação de propostas de diretrizes para políticas públicas de habitação social com desenvolvimento
local, adotou-se a estratégia do estudo de caso único exploratório do município de Itararé, localizado na região sudoeste do estado de São Paulo, a partir da experiência de
formulação de políticas públicas de habitação social com desenvolvimento regional pelo Projeto Habitação Social em Madeira como Alternativa Econômica para Usos Múltiplos
da Floresta . O estudo desse caso visa compreender o fenômeno da atuação de diferentes agentes naquela região durante o processo de elaboração de diretrizes de políticas públicas. A unidade analisada refere-se à experiência de elaboração de propostas de políticas públicas no município de Itararé, onde se distinguem como categorias de análise sujeitos (representantes da administração, representantes da sociedade organizada, iniciativa privada, pesquisadores e outros representantes de marcenarias e serrarias do município)
que participaram do processo de formulação de programas de políticas públicas no município.Com a utilização da revisão da literatura, da sistematização de dados, da observação direta e de entrevistas, constatou-se que existem limites que dificultam ao pequeno município elaborar suas próprias políticas públicas. Tais limites estão associados a diversos fatores relacionados aos agentes que compõem o projeto: poder público, população local, iniciativa privada, universidade e outros parceiros. A partir da análise da participação destes atores na experiência conduzida em Itararé, concluiu-se que não houve a interação necessária entre a administração municipal, o setor produtivo da cadeia da madeira, a população organizada e a assessoria técnica, para que fosse consolidado o Projeto no município.

Gröna tak och hållbar urban utveckling : en fallstudie av stadsutvecklingsprojektet Norra Djurgårdsstaden i StockholmAndersson, Sara, Sundström, Lovisa January 2020 (has links)
Mänskligheten står inför en framtid med klimatförändringar och utmaningar i form av återkommande värmeböljor, ökad nederbörd, urbanisering samt minskad biologisk mångfald. Det blir allt mer attraktivt att bosätta sig i städer och i kombination med befolkningsökningen sker det en snabb global urbanisering. Detta leder till hög exploateringshastighet i våra städer då andelen hårdgjorda ytor ökar och andelen gröna ytor minskar. Vid byggandet av fastigheter tillkommer en stor mängd outnyttjade ytor, ofta i form av mörka tak. Dessa är inte bara outnyttjade ytor på dyr tomtmark utan skapar ytterligare problem kopplade till urbanisering i form av bland annat minskat albedo. Närhet till grönska gör att människor mår både fysiskt och psykiskt bättre vilket avspeglar sig i en högre betalningsvilja för bostäder i närhet till grönska. Privatpersoner samt fastighetsägare vill gärna profilera sig som hållbara då hållbarhet på senare tid kommit att bli en identitetsskapande “statusmarkör”. Hållbara bostäder kan därmed vara en säljande faktor. Grönska på taken är i sig inget nytt påfund men har senaste åren fått en renässans i Sverige då det visat sig kunna ge fördelar såsom tillgång till grönska för de boende, dagvattenhantering, minskad värmeöeffekt och bättre luftkvalitet. Syftet med studien har varit att undersöka hur ett av Europas mest omfattande stadsutvecklingsprojekt, Norra Djurgårdsstaden i Stockholm, arbetar med hållbar urban utveckling genom gröna tak. De gröna taken kan generera en mängd ekonomiska, ekologiska och sociala fördelar i städer. I studien används urban hållbarhetsteori samt ett egenkonstruerat analysramverk baserat på avsnittet tidigare forskning och teori. Genom en kvalitativ innehållsanalys samt semistrukturerade intervjuer har det framkommit i denna studie att den sociala dimensionen av hållbar stadsutveckling utifrån gröna tak i Norra Djurgårdsstaden överskuggas av de två andra aspekterna; ekonomiskt och ekologiskt. Detta trots att hållbarhetsarbetet med Norra Djurgårdsstaden tagit med alla tre aspekter inom hållbar utveckling; ekonomiskt, ekologiskt och socialt i beaktande när det kommer till planering av stadsdelen. / Humanity is today facing a future with climate change and challenges in the form of periodic heatwaves, increased rainfall and reduced biodiversity. The urbanization processes are driven by expanded population growth and it’s becoming more attractive to live in the cities. This causes the dimension of hard surfaces to increase and consequently the proportion of green spaces sinks. In the construction of housing, a large amount of unused space is added in form of dark areas on roofs. These are not only unused areas on expensive land but create additional problems linked to urbanization in the form of decreased albedo. Furthermore, citizens' willingness to pay has been shown to rise with closeness to green surfaces which can provide recreational and health benefits. Private individuals and property owners would like to profile themselves as sustainable, as the term “sustainability” recently has become an identity-created “status marker”. Sustainable housing can therefore also be a selling factor. Green roofs are not a new invention but have had a renaissance over the years as it has proven to provide the availability to green surfaces for the citizens, stormwater management, heat island effect, and provide healthier air quality. The aim of the study was to examine how the district Norra Djurgårdsstaden in Stockholm, Sweden works with sustainable urban development through green roofs. In this study we have used urban sustainability theory as the green roofs can generate a wealth of economic, ecological and social benefits in urban areas. We have also used our own constructed analysis framework based on previous research and urban sustainability theory. By doing a qualitative content analysis, as well as semi-structured interviews, it has appeared that the social dimension of urban sustainable development in Norra Djurgårdsstaden is overshadowed by the two other aspects; the economic and the ecological. Although the sustainability work in Norra Djurgårdsstaden has taken all three aspects; economic, ecological and social into account when it comes to planning of the district, the social aspect is often neglected.

Den urbana miljöns inverkan på människors upplevelser / Impact of the urban environment on people's experiencesSkoglund, Sara January 2021 (has links)
Den mänskliga populationen har tredubblats på 70 år och det råder konsensus om att människan är den dominerande faktorn till klimatförändringarna och den negativa påverkan på ekosystemens processer. Det betonar att den globala utvecklingen främst vilar i mänsklighetens händer, inte minst den urbana utvecklingen då städer i hög grad driver på klimatpåverkan. Därför behövs social-ekologiska hållbara system i städerna utvecklas för att bidra till global hållbarhet och för att främja människors välbefinnande. I städer är grönområden viktiga för människors välbefinnande och gynnar även den ekologiska anknytningen som är betydande för miljöfrämjande värderingar vilket understryker vikten av invånares integreringsmöjligheter med grönområden. Studier pekar däremot på att upplevd otrygghet kan hindra integreringen med grönområden och att kvinnor i högre utsträckning upplever barriärer än män. Samuelsson, Peterson, Legeby, Brandt, & Barthel (2018) studie syftade till att undersöka människors upplever i Stockholm ur ett miljöpsykologiskt perspektiv. Med den studien som utgångspunkt syftar detta examensarbete till fördjupad förståelse för hur den urbana miljön påverkar registrerade upplevelser baserat på upplevd trygghet och även ur ett könsperspektiv. Samuelsson et al. (2018) utgick från en upplevelse- och deltagande baserad metodik för att förena rumsliga och erfarenhetsmässiga aspekter. I detta examensarbete utfördes därmed två statistiska kvantitativa analyser där den första syftade till att studera samband mellan upplevelser baserat på upplevd trygghet och miljökvalitet. Resultatet visade att positiva trygga upplevelser registrerats främst i grönområden och negativa otrygga i byggd stadsmiljö. Baserat på så få negativa registrerade upplevelser i grönområden syftade den andra analysen till att enbart analysera skillnaden mellan kön och positivt registrerade upplevelser i grönområden och i byggd stadsmiljö. Resultatet visade att kvinnor skattar både byggd stadsmiljö och grönområden i högre grad än män. Resultatet visade även att grönområden i högre grad skattats som positiva än byggd stadsmiljö. Det fanns ingen interaktionseffekt mellan kön och miljökvalitet, men en tendens till ett signifikant resultat. Utifrån behovet att utveckla hållbara social-ekologiska system i städer för att främja global hållbarhet finns även ett behov att studera människors upplevelser i den urbana miljön. Utifrån resultaten i examensarbetet dras slutsatsen om att åtgärder i stadsutvecklingsprocessen främst bör riktas att designa den byggda stadsmiljön för att främja människors välbefinnande och att grönområden ska bibehållas och stärkas. Studier har visat på att kvinnor i högre utsträckning upplever barriärer för att interagera med grönområden men detta resultat visade inga belägg för det utan tvärtom att kvinnor skattar upplevelser i grönområden högre än män. Därmed anses det vara intressant att i framtida studier studera andra individuella skillnader som kan påverka upplevelserna, exempelvis fysiska och psykiska barriärer. Det vore även intressant att vidare studerar hur element i den urbana miljön, som belysning och bullernivåer, påverkar människors upplevelser och upplevda trygghet. Dessutom bidrar det här examensarbetet med betydande förbättringsförslag till hur framtida PPGIS-undersökningar kan utformas för att förbättra analysmöjligheterna. / The human population has tripled in 70 years and there is a consensus that humankind is the dominant factor in climate change and that ecosystem processes are adversely affected. It emphasizes that global development is primarily in the hands of humanity and, not least, the urban development as cities are greatly driving climate change. This requires sustainable urban systems to contribute to global sustainability and to promote people's well-being. In cities, green spaces are particularly important for people's well-being and also promote the ecological connection that is important for environmental-promoting values. It underlines the importance of residents' integration opportunities with green spaces. Studies, on the other hand, suggest that perception of unsafety can hinder integration with green spaces and that women experience barriers to a greater extent than men. Samuelsson, Peterson, Legeby, Brandt, & Barthel (2018) study aimed to investigate people's experiences in Stockholm from an environmental-psychology perspective. Based on this study, this thesis aims at a deeper understanding of how the urban environment affects experiences based on perceived safety and from a gender perspective. Samuelsson et al. (2018) study was based on an experience- and participation-based approach to combining spatial and experiential aspects. In this work, two quantitative statistical analyses were carried out in which the first analysis was aimed to study whether there were links between experiences, based on perceived safety, and environmental quality. The result showed that positive safe experiences were recorded mainly in green areas and negative unsafe in built urban environments. Based on a small percentage of negative experiences in green areas the second analysis aimed to analyze only the difference between gender and positively recorded experiences in green areas and in built urban environments. The results showed that women estimating both built urban environment and green spaces in a higher grade than men based on perceived safety. The results also showed that green spaces were more appreciated as positive experiences than built urban environments. There was no statistical interaction between gender and environmental quality, but a tendency of a significant result. Based on the necessity to develop sustainable social-ecological systems in cities to promote global sustainability, there is also a need to study people's experiences in the urban environment. Based on the results of this thesis, it is concluded that actions in the urban development process should primarily focus on designing the built urban environment in order to promote people's well-being and green spaces should primarily be maintained and strengthened. Studies have shown that women in a greater extent experience barrier to integrate with green spaces, but this thesis showed no evidence of this, instead women rate experiences in green spaces higher than men. Therefore, it is considered interesting to study individual differences that can affect experiences instead, such as physical and mental barriers. It would also be interesting if future studies aimed to study how elements of the urban environment, such as lighting and noise levels, affect people's experiences and perceived safety. In addition, this thesis contributes significant improvement proposals to how future PPGIS surveys can be designed to improve analysis opportunities.
