Sustainable development is gaining more focus than ever, and sustainable urban water management is increasingly being incorporated in urban planning worldwide. Internationally, certification systems for sustainable urban planning have gained popularity, and a Swedish version of the British certification system BREEAM Communities is on its way. In this degree project the technical water related aspects of the certification system BREEAMCommunities are analyzed and compared with the corresponding aspects of the American certification system LEED for Neighborhood Development. Water related aspects of both systems are discussed on basis of research in sustainable urban water management. Difficult questions raised in managing the urban water of the future are e.g. climate changes and new technical solutions for storm water management.

abstract: Urban sustainability is a critical component of sustainable human societies. Urban riparian parks are used here as a case study seeking to understand the social-ecological relationships between the subjective evaluation of ecosystem services and the vision and management of one kind of green infrastructure. This study explored attitudes towards ecosystem services, asking whether 1) the tripartite model is an effective framing to measure attitudes towards ecosystem services; 2) what the attitudes towards ecosystem services are and whether they differ between two types of park space; and 3) what the relationship is between management and the attitudinal assessment of ecosystem services by park users. A questionnaire was administered to 104 urban riparian park users in Phoenix, AZ evaluating their attitudes towards refugia, aesthetics, microclimate and stormwater regulation, and recreational and educational opportunities. The operationalization of the tripartite model was validated and found reliable, but may not be the whole story in determining attitudes towards ecosystem services. All components of attitude were positive, but attitudes were stronger in a habitat rehabilitation area with densely planted native species and low flows, than in a more classic park with mowed lawns and scattered vegetation, a mix of native and non-native species, and open water. Park users were more positive towards refugia, stormwater regulation, recreation, and educational opportunities in the habitat rehabilitation area. On the other hand, microclimate regulation and aesthetic qualities were valued similarly between the two parks. Most attitudes supported management goals, however park users valued stormwater regulation less than managers. Qualitative answers suggest that the quality of human interactions differ between the parks and park users consider both elements of society and the physical environment in their subjective evaluations. These findings reveal that park users highly value ecosystem services and that park design and management mediates social-ecological relationships, which should at least underlie the context of economic discussions of service value. This study supports the provision of ecosystem services through green infrastructure and suggests that an integration of park designs throughout urban areas could provide both necessary services as well as expand the platform for social-ecological interactions. / Dissertation/Thesis / M.S.

The world is urbanizing at an unprecedented rate, and cities are dominantly and increasingly becoming hubs for agglomerations of human population and economic activities, as well as major sources of environmental problems. Accordingly, humanity′s pursuit of global sustainability is becoming increasingly reliant on urban sustainability. Unfortunately, the traditional approaches of urbanization and urban stormwater management are inappropriate from the sustainability standpoint. By removing vegetation and topsoil and creating impervious structures, urbanization destroys natural biodiversity and hydrological processes. As a result, urban societies are disconnected from nature and deprived of ecosystem services including flood control, fresh air, clean water, and natural beauty. Due to disrupted hydrology, an urban landscape transforms most rainwater into stormwater runoff which is conveyed off the site through a system of curb-gutter-pipe, called gray infrastructure. While gray infrastructure efficiently mitigates the problem of flash floods in urban areas, it results in multiple other adverse environmental consequences such as loss of freshwater from urban landscapes, transfer of pollutants to receiving waters, and an increased potential of downstream flooding. Green infrastructure (GI) is regarded as a sound alternative that manages stormwater by revitalizing the natural processes of soil, water, and vegetation, and restoring ecosystem structures and functions. Thus, the approach re–establishes the lost socio–ecological connectivity and regenerates ecosystem services. However, despite being inevitably important for urban sustainability, and despite being the object of unrelenting expert advocacy for more than two decades, the approach is yet to become a mainstream practice. To widely implement GI, cities need to address two critical challenges. First, urban stormwater managers and decision makers should be ensured that the approach can adequately and reliably manage stormwater. In the time when flooding problems are rising due to climate change, this concern has become more prominent. Second, if there exist any other barriers, they should be replaced with strategies that help expedite the use of GI. This multidisciplinary research dealt with these two challenges. The study consisted of two major parts. In the first part, a computer model was developed for a combined sewer system of St. Louis, a city in the US state of Missouri, using U.S. EPA SWMM. Simulations for historical (1971-2000) and future (2041-2070) 50-yr 3-hr rainfall scenarios were then run on the model with and without GI. The simulation results showed a significant impact of increased precipitation on the system, which was considerably reduced after adding select GI measures to the modeled system. The following 4 types of GI were used: bio–retention cell, permeable pavement, green roof, and rain barrel. In the second part, a survey of relevant policies and governance mechanisms of eleven U.S. cities was conducted to identify potential barriers to GI and determine strategies to address them. The study also included the assessment of relevant city, state, and federal policies and governance structures. A total of 29 barriers were identified, which were grouped into 5 categories. Most of the identified barriers stem from cognitive barriers and socio–institutional arrangements. A total of 33 policies, also grouped into 5 groups, were determined to address the barriers. The investigation on governance revealed that current governance is highly technocratic and centralized, and hence has less opportunity for public involvement. Therefore, it is inherently inappropriate for GI, which requires extensive public involvement. This dissertation proposes a two–tier governance model suitable for implementing GI.

Seguindo os rastros deixados pelos rios urbanos no curso da história, entendemos a importância do estudo e incorporação da paisagem nos projetos de infraestrutura urbana. Esta pesquisa busca entender uma das principais dificuldades encontradas em muitas cidades brasileiras: as enchentes. Através de consultas bibliográficas, foi possível encontrar na conceituação de paisagem, uma base teórica para analisar a relação dos rios com a cidade de Bauru/SP, a partir das cinco portas da paisagem de Jean-Marc Besse. Cada porta possibilita uma abordagem diferenciada da paisagem urbana, que serão usadas como ferramentas metodológicas para percepção da interação entre o objeto de estudo – o Córrego das Flores – e a paisagem de Bauru. Ainda com o auxílio de bibliografias, apoiadas por documentos, fotos e reportagens obtidas em arquivos municipais, foi analisado o desenvolvimento e expansão da cidade para explicar o contexto no qual o objeto – e o lugar onde se insere – foi transformado, bem como a identidade da população para com o córrego e a nova Avenida Nações Unidas, durante as obras no século XX e nos dias atuais, nos quais convivem com enchentes e alagamentos frequentes. Apresentando medidas sustentáveis para a mitigação das enchentes, o questionário aplicado com os moradores de Bauru e as entrevistas com especialistas em drenagem, engenharia e arquitetura, reafirmam a importância de restabelecer a ligação entre homem e natureza no meio urbano, revitalizando os espaços livres e naturais remanescentes, e agindo como conexão entre moradores e governantes para alcançar tanto uma qualidade de vida melhor quanto uma paisagem equilibrada. / The urban transformations that happened during the 20th century had a fundamental role on the current configuration of cities, being also the cause of some adversities in the urban environment. Following the trails left by urban rivers in the course of history, we understand the importance of the study and incorporation of the landscape in the urban infrastructure projects. This research seeks to understand one of the main difficulties found in many Brazilian cities: the floods. Throughout bibliographic queries, it was possible to find in the conception of landscape, a theoretical basis to analyze the relation of rivers with the city of Bauru/SP, through the five landscape doors of Jean-Marc Besse. Each door allows the study of a particularity of the urban landscape, which will be used as methodological tools for the perception of the interaction between the object of study – o Córrego das Flores – and Bauru’s landscape. Allied with the contribution of bibliography, supported by documents, photos and reports obtained from municipal archives, it was analyzed the development and expansion of the city to explain the context in which the object – and the place its place – was transformed, as the identity of the population with the stream and the new Avenida Nações Unidas, during the constructions on the XX Century and in the current days, in which coexist with frequent floods and overflows. Presenting sustainable measures for floods mitigation, the questionnaire applied with Bauru’s inhabitants and the interviews with specialists in draining, engineering and architecture, reinforce the importance of reestablishing the connection between human and nature on the urban environment, revitalizing the remaining free and natural spaces, and acting as a connection between inhabitants and leaders, to reach both a better quality of life and a more balanced landscape. / CAPES: 1708730

Faz parte dessa infraestrutura a arborização de ruas e avenidas, conhecida como arborização viária, que em geral é feita sem planejamento e, por isso, gera os mais diversos conflitos com outros importantes sistemas urbanos. Um dos problemas recorrentes é a falta de normas que garantam à diversidade arbórea, o sombreamento adequado, a manutenção e incentivo a flora e fauna locais. Nesse contexto, essa pesquisa visa contribuir com a proposição de um método de avaliação da qualidade da arborização viária, a partir de parâmetros espaciais e ambientais. Esse método é validado em um estudo de caso em um bairro de Bauru, cidade do centro oeste paulista. Os resultados indicam que a área analisada possui uma arborização viária parcialmente adequada, cujos principais problemas são: a composição de espécies, que possui uma variedade bem menor que a recomendada, o que facilita na propagação de pragas e doenças; a altura média da primeira bifurcação abaixo da recomendada pelas normas de acessibilidade, o que é causa da grande porcentagem de árvores de pequeno porte; e a média para a área livre de pavimentação, que apresentou também bem abaixo do encontrado na literatura, o que prejudica o desenvolvimento do indivíduo arbóreo. O método proposto é efetivo na identificação de problemas e pode auxiliar na caracterização da área e na tomada de decisões para planejamentos futuros. / Urban green infrastructure planning has become increasingly essential in order to combat the adverse effects of urbanization, contribute to the physical and mental health of its inhabitants and favor a better quality urban life. The urban infrastructure has as its part the afforestation of streets and avenues, known as road forestation, which is usually done without planning and, therefore, generates the most diverse conflicts with other important urban systems. One of the recurring problems is a lack of standards to ensure tree diversity, adequate shading, maintenance and encouragement of local flora and fauna. In this context, this research aims to contribute to the proposition of a method to evaluate the quality of road arborization, based on spatial and environmental parameters. This method is validated in a case study in a neighborhood of Bauru, in the midwest of state of São Paulo. The results indicate that the area under study has a partially adequate afforestation. Three main problems have been identified for an area: a species composition, which has a much smaller variety than a recommendation, which facilitates the spread of pests and diseases; the average height of the first bifurcation was below that recommended by the standards of accessibility, which is the cause of the large percentage of small trees; and the average for the paving free area was also well below in the literature, which impairs the development of the arboreal individual. The method was effective in the identification of problems, which may help in characterizing the area and making decisions for future planning.

O presente trabalho propõe uma nova estratégia de planejamento da paisagem urbana para aquisição de novas áreas verdes, através da recuperação e restauração de áreas degradadas (locais vazios, abandonados e subutilizados). A urgência de intervenção e revitalização destas áreas tem sido foco de preocupação nos grandes centros urbanos, tanto em países desenvolvidos, como nos emergentes, uma vez que são espaços disfuncionais no tecido urbano. O estado de abandono e desinteresse leva a depreciação do entorno e facilita o uso à criminalidade e atividades ilícitas. A transformação das áreas degradadas em espaços vegetados visa transformar o problema em oportunidade, partindo do princípio de que as áreas verdes devam cumprir funções infraestruturais, ou seja, ser componente de uma paisagem de alta performance, contribuindo para a criação ou ampliação da infraestrutura verde urbana. O estudo de caso para aplicação desta nova estratégia foi parte da cidade de São Bernardo do Campo, na região metropolitana de São Paulo, Brasil, cujas diminutas áreas verdes urbanas acessíveis à comunidade são cada vez mais escassas, ao mesmo tempo em que há diversas áreas vazias e abandonadas, muitas em processo de regeneração natural, que são alvos do mercado imobiliário para residências, serviços e comércio. A partir desta temática, uma série de questões foi lançada: Quais áreas degradadas têm potencial para serem convertidas em áreas verdes? Quais são os critérios para avaliação deste potencial? Qual é o caráter vocacional destas futuras áreas verdes: ambiental ou social? Essas perguntas nortearam o desenvolvimento da pesquisa em busca de uma metodologia de planejamento paisagístico para aquisição de novas áreas verdes aplicada na cidade de São Bernardo do Campo. Assim, foi desenvolvida uma ferramenta de avaliação, que se utilizou de um sistema de informação geográfico, e está pautada nos princípios de infraestrutura verde, de forma a responder às questões ecológicas, de drenagem das águas, de mobilidade, e as questões sociais de atendimento à comunidade local. Os resultados mostraram que 40% das áreas amostrais avaliadas apresentaram potencial alto de conversão em áreas verdes, outros 40%, potencial médio e 20% restante, potencial baixo, apontando um cenário favorável para a maioria das áreas degradadas. Quanto ao seu uso vocacional, 50% apresentam potencial de uso predominantemente social, 20% ambiental e 30% social e ambiental. A classificação por vocação de uso das áreas verdes (social ou ambiental) é um dado importante, uma vez que aponta áreas com potencial inferior e que não devem ser descartadas, pois tem um valor social importante. Os resultados têm por finalidade auxiliar nas tomadas de decisão preliminar do planejamento urbano ambiental, oferecendo subsídios aos profissionais da área na proposição criteriosa de novas áreas verdes urbanas. / This research proposes an urban landscape planning strategy for the acquisition of new green areas, through the reclamation of vacant, derelict and underused lands. Authorities in large urban centers, both in developed and emerging countries, have been concerned in these sites, once they are dysfunctional areas in the urban fabric. The carelessness and indifference has led to depreciation of the surrounding and facilitates the increase of crime. Greening derelict, vacant and underused lands can transform a problem into an opportunity, assuming that green spaces must fulfill infrastructural functions, as part of a landscape of high performance, seeking the creation or expansion of an urban green infrastructure. The case study to apply this strategic planning approach was Sao Bernardo do Campo city, in Sao Paulo Metropolitan area, Brazil, whose the tiny accessible green areas to the community are increasingly scarce, while there are many vacant, derelict and underused lands, under natural regeneration process, that are acquired for real estate market instead of creation of new greenspaces. From this point view, a series of questions were made: Which vacant, derelict and underused lands have the potential to be reclaimed into green areas? What are the criteria to evaluate this potential? Which the main role and potential use of the green area: social or environmental use? These questions guided the research in the development of a landscape planning methodology to acquire new green areas in São Bernardo do Campo. An assessment tool, using GIS and based on green infrastructure concept was developed, so that derelict and vacant lands could meet ecological, stormwater management, mobility and social issues. The results showed that 40% of the sample sites presented high potential to reclaim into green areas, 40%, medium potential and 20%, have low potential, revealing a favorable scenario for most vacant and derelict lands. Regarding the role and use of the green area, 50% have a predominantly social potential use, 20% environmental potential use, and 30% presents both potentials. This classification (social and/or environmental) is an important point, since it identifies those areas that, despite have lower potential, should not be discarded because it has an important social value. The results should assist a preliminary environmental and urban planning decision making, offering support to professionals to insightful creation of new urban green areas.

Urban populations worldwide are expanding rapidly and consequently a large number of people are becoming exposed to hazards inherent in cites. Phenomena such as the urban heat island can exacerbate the effects of heatwaves, and land surface sealing can lead to flash flooding. Cities are also the sites of enhanced air and water pollution from non-point sources such as concentrated motor vehicle use. Climate change predictions for the UK include increased winter precipitation and an increase in frequency of summer heatwaves. This will put further pressure on urban residents and infrastructure. Roof greening can be used within climate change adaptation schemes because green roofs have a range of environmental benefits which can help urban infrastructure become more sustainable. This thesis empirically quantifies several of these benefits, and the processes influencing them, by monitoring real green roofs in Manchester. A number of novel discoveries were made. Green roofs act as passive filters of airborne particulate matter. 0.21 tonnes of PM10 (2.3% of the inputs) could be removed from Manchester city centre in a maximum extensive green roof scenario. Species and site differences in particle capture were exhibited and related to morphology and proximity to sources respectively. An intensive green roof was able to lower the monthly median overlying air temperature at 300 mm by up to 1.06 oC. A combination of drought and mismanagement caused damage to the vegetation on one of the green roofs, with a subsequent reduction in the cooling effect. Daytime air temperatures were higher than over an adjacent bare roof for a larger proportion of the day than over the undamaged roof, and lower cooling was observed at night. A site-specific methodology was devised to monitor the rainwater runoff from an intensive green roof and an adjacent bare roof. Average runoff retention of 65.7% was observed on the green roof, compared to 33.6% on the bare roof. Season and rainfall amount had significant impacts on retention, however, many other explanatory variables such as Antecedent Dry Weather Period (ADWP) and peak rainfall intensity had no demonstrable, significant impact. Intensive roof construction on 10% of the rooftops in Manchester city centre would increase annual rainfall retention by 2.3%. The runoff was characterised with regards to heavy metals and nutrients. Nutrient levels were found to be not a significant problem for water quality, however, Environmental Quality Standards (EQS) values for protection of freshwater were exceeded for concentrations of Cu, Pb and Zn. High metal concentrations within the sediments may be acting as sources of pollution, particularly in the case of Pb. The age of the green roof means that past atmospheric deposition of Pb could be contributing to the runoff quality. The multi-benefit aspect of green roofs is discussed in the light of the results of this thesis and recommendations made for policy makers and the green roof construction industry.

The purpose of this document is to develop a concept for action plans within the framework of SALUTE4CE project, specifically, for urban pilot project areas where urban environmental acupuncture is being applied and their respective Functional Urban Areas (FUAs). The action plan concept incorporates the methodology for selecting urban environmental acupuncture (UEA) sites and this includes the typology and selection of interventions created within the SALUTE4CE project. The transnational action plan concept is comprised of three main sections: general considerations, creating local action plans and plan implementation.

As the planet rapidly urbanizes and demand for locally-produced ecosystem services grows, the effective management of urban green infrastructure is increasingly important. A number of digital tools have recently been developed and released that share information and incite citizen participation in the governance, management and planning of urban green infrastructure. In this paper, I analyse six different e-tools within the context of New York City with a focus on the types of knowledge they share and the forms of participation they incite in relation to urban green infrastructure. I explore how e-tool knowledge exchange and participation relate to civic stewardship of urban green spaces, as stewards play a significant role in the local production of urban ecosystem services. The findings indicate that most e-tools are designed to share a large amount of data describing social-ecological systems. In many cases, the tool developers hope that through gaining knowledge about the system, users will develop an ethical consideration for the environmental resource and even take action as environmental stewards. Additionally, while many of the e-tools present complex, exploratory digital learning environments, many also combine virtual experiences with in-person trainings, workshops and coaching. These hybrid approaches harness the power of digital platforms to organize diverse social networks and share large amounts of data while employing more traditional on-the-ground organizing techniques and offer a way forward in an age of increasing dominance of digital data. Further research on these types of hybrid digital approaches is warranted. Future research on e-tool usership and connections to stewardship outcomes could enrich the understanding of how e-tools operate as well as their social-ecological potential and impact.

This study provides an evaluation of the performance of the WinSLAMM model in two cities of northern Utah, a region in which it has not been validated to date. Runoff volumes for a series of events from 2015 to 2017 were calculated for six study areas. These results were compared to model outputs to evaluate the prediction accuracy. The model performed poorly when default parameters where used, as expected. Thus, the calibration of runoff coefficient was done with local data. Total suspended solids (TSS), total phosphorus (TP) and total dissolved phosphorus (TDP) were also evaluated and calibrations were developed. The WinSLAMM model performed well for TSS prediction and TP and TDP estimations were calculated with the TP/TSS and TDP/TP ratios observed in the data for the Logan study areas. Three scenarios of GI implementation were analyzed; the treatment of 10%, 50% and 100% of connected impervious surfaces. For the 10% case, treating streets produced the greatest TSS reduction, while treating roofs yielded the greatest volume reduction. For the 50% case, there was a great difference in TSS reduction with varying surfaces. Implementing GI for streets produced the largest TSS reduction, followed by parking lots and then by roofs.
