The world is increasingly urbanizing with approximately 54% of the world population livingin cities (Langemeyer, 2015). This number is expected to rise to 66% by 2050 (UN, 2014),which means that urbanized areas will expand in size with an additional 2.5 billion new urbaninhabitants (Langemeyer, 2015). Studies show that urban expansion has the effect ofdecreasing, fragmenting, and isolating natural patches by altering the size, shape, andinterconnectivity of the natural landscape (Ricketts, 2001; Alberti, 2005). The consequentloss and degradation of urban and peri-urban green/blue space and elements couldadversely affect ecosystem and its services as well as human health and well-being.Through literature review, the concepts of urban ecosystem services and green-blueinfrastructures are introduced, as well as the main design principles for green-blueinfrastructures. The thesis also briefly introduces urban policies and implementation throughcase study with a focus on Malmö city. Meanwhile, the thesis discusses how the planninginstruments of Green Space Factor and Green Points are used in the Bo01 project and howthey contributed to promote ecosystem services in built environment.Through literature review and case study, the aim of this thesis is to collect design solutionsthat can be used as inspiration and guidance to promote urban ecosystem services throughgreen-blue infrastructures in built environments at different scales.

Living shorelines and other nature-based solutions have become more widely accepted as a cost-effective, multi-functional, and sustainable approach to coastal resilience. However, in spite of growing stakeholder support, a planning-level understanding of the hydrodynamic impact of living shorelines is not well-developed. Not only do these features vary in size, shape, and structural characteristics, but the wave environment in which they exist can be quiescent or extreme. The work presented in this paper explores the hydrodynamic effects of living shoreline features in such a way that can be generalized across a range of varying physical environments. In a series of Simulation WAves Nearshore (SWAN) simulations, we investigate the effect of wave period, wave height, bed slope, living shoreline feature length in the cross-shore direction, and feature friction coefficient on wave attenuation. Results showed that higher wave period, higher wave height, milder slopes, longer feature lengths, and higher feature roughness largely correlated with higher wave attenuation. However, only on mild slopes did additional feature lengths result in appreciable additional attenuation. Characteristic lengths were thus computed to better illustrate the cost-effectiveness of additional feature lengths given a particular wave environment. These characteristic lengths provide one way to evaluate the hydraulic efficacy of proposed living shoreline projects. In this way, regardless of the particularities of individual project sites, we aim to help planners screen potential living shoreline projects before pursuing more detailed, costly analyses. / Master of Science / Living shorelines and other nature-based solutions have become more widely accepted as a cost-effective, multi-functional, and sustainable approach to coastal resilience.

Stadsplanerare står inför framtida utmaningar med fortsätt förtätning av städer och ökade risker i och med klimatförändringarna. För att få plats för alla samhällsfunktioner som behövs i de kompakta städerna, däribland klimatanpassningsåtgärder, finns det ett behov av mångfunktionella lösningar. Grönblå infrastruktur har en mångfunktionell karaktär och kan användas för att kombinera hantering av översvämningar, värmeböljor och andra samhällsfunktioner i samma lösningar. Trots att dessa fördelar är tydliga i forskningen kvarstår det svårigheter i att implementera lösningarna i praktiken. Syftet med denna uppsats är att studera förutsättningar för implementering av mångfunktionella grönblå lösningar. Detta har gjorts i tidigare studier, men inte med fokus på planering av nya stadsdelar, vilket kommer vara fokus i denna studie där stadsdelen Hyllie i Malmö används som studieobjekt. Analysen grundas på kvalitativa semistrukturerade intervjuer med tjänstemän från olika avdelningar på kommunen som är involverade i stadsplaneringen. Resultatet visar att de främsta förutsättningarna för implementering är väl fungerande samverkan, kunskap, regleringsmöjligheter, finansiella resurser och politiskt stöd för prioritering av grönblå strukturer. För att förbättra dessa förutsättningar finns det möjligheter för kommunen att utveckla samverkan inom organisationen och med utomstående aktörer och gå mot mer förenade mål och gemensamt ansvar. En annan möjlighet är att genom arbetet i pilotprojekt utveckla nya lösningar för reglering samt öka kunskapen om grönblå strukturer. Här är utmaningen att integrera erfarenheterna i projekten i kommunens kärnarbete. / Urban planners will have to handle future challenges due to the densification of cities and the increased risks resulting from climate change. In order to accommodate all the community functions needed in the compact cities, including climate adaptation measures, there is a need for multifunctional solutions. Green-blue infrastructure is multifunctional in its nature and can be used to combine management of floods, heat waves and other community functions in the same solutions. Although these benefits are clear in research, difficulties remain in implementing the solutions in practice. The aim of this paper is to study the prerequisites for implementing multifunctional green-blue solutions. This has been done in previous studies, but not with a focus on planning new neighbourhoods, which will be the focus of this study where the Hyllie district in Malmö is used as a study object. The analysis is based on qualitative semi-structured interviews with officials from various departments of the municipality who are involved in urban planning. The results show that the main prerequisites for implementation are well-functioning collaboration, knowledge, regulatory opportunities, financial resources and political support for prioritizing green-blue structures. To improve these conditions, there are opportunities for the municipality to develop collaboration within the organization and with external actors and move towards more unified goals and shared responsibility. Another possibility is to work with pilot projects to develop new solutions for regulation and to increase the knowledge of green-blue structures. Here, the challenge is to integrate the experience of the projects into the municipality's core work.

Worsening climate change impacts, particularly in coastal areas, are forcing urban planners and designers to find new approaches to govern cities. Traditional government approaches are failing to equip cities with effective strategies on how to implement sustainable interventions such as green and blue infrastructure. Adaptive governance has emerged as a way of dealing with the inherent uncertainty and unpredictability of complex social-ecological systems. It is neither top-down nor bottom-up but involves innovative ways of solving problems with emphasis on collaborative decision-making. This research focuses specifically on how collaboration is undertaken in adaptive governance processes by examining The Soul of Nørrebro case study—an integrated urban design and climate adaptation project for Hans Tavsens Park and Korsgade in Copenhagen, Denmark. Through desk study and interviews, the study identifies which stakeholders are involved in collaborative decision-making processes and how stakeholders envision, implement, and contest collaborative decision-making in The Soul of Nørrebro green and blue infrastructure project. This research found that participation from a wide range of local stakeholders and citizens is an integral part of redesigning public space, as it helps create cohesive, just, and ecologically productive environments. However, trade-offs that result in political decisions that are desirable to some and not to others cannot be avoided in the end. While certain setbacks were unavoidable, others that were encountered could have perhaps been prevented through increased transdisciplinary and representative collaboration.

Our planet stands before many great challenges, where climate change and urbanization are two of the major challenges. One of the challenges due to climate change is the increased amount of precipitation and of extreme rainfall, which creates a higher amount of stormwater within the urban areas and an increased risk of urban flooding. Urbanization and an increasing global population put pressure on the environment as more land is exploited and existing urban areas are further developed and densified. Urban areas are already under high pressure to handle the risks of climate change, therefore is climate change adaptation prominent to create more resilient and sustainable urban areas, where stormwater management is one of the challenges that need to be tackled. The aim of this study is to answers one main research question and three sub research question about enablers, barriers, and key factors regarding planning, designing, and implementing sustainable urban drainage systems in the built environment. The used methods are literature study research and multiple case study research. Five case study areas where studied to gather knowledge about areas that have implemented sustainable urban drainage systems. Lessons learned for each of the case study areas where gathered and connected to the literature and used to answer the research questions. The gathered knowledge from the literature and case studies where used to compile recommendations of how a sustainable urban drainage system could be planned and implemented at a pilot study area, which is Välsviken in Karlstad, Sweden. To be able to achieve a sustainable and resilient urban drainage system, that can handle the challenges of climate change and urbanization, it is important that the stormwater planning process is changing. It is crucial to implement facilities and systems that are sustainable, multifunctional, and flexible. The planning process needs to use planning and costing approaches that include flood mitigation and co-benefits, in the long-term and short-term simultaneously. Implementation of sustainable urban drainage systems also needs to be enabled in new areas or being retrofitted into already exploited areas. This could make it possible to create urban areas that are able to tackle the challenges of climate change and urbanization, and create multifunctional, sustainable, and flood mitigated urban areas. / Vår planet står inför många stora utmaningar, där klimatförändringar och urbanisering är två av dessa. En av utmaningarna med avseende på klimatförändringarna är den ökade mängden av nederbörd och extrema regntillfällen, vilka bidrar till större mängder dagvatten i urbana områden och en ökad risk för översvämningar. Urbaniseringen och det ökande antalet invånare globalt sätter press på miljön eftersom mer landyta exploateras och nuvarande urbana områden fortsätter att bebyggas och förtätas. De urbana områdena har redan stora utmaningar med att hantera riskerna med klimatförändringarna. Klimatanpassning är därför viktigt för att skapa mer resilienta och hållbara urbana områden, där dagvattenhanteringen är en av utmaningarna som behöver hanteras. Målet med denna studie är att besvara en övergripande forskningsfråga och tre underliggande forskningsfrågor om möjliggörare, barriärer och nyckelfaktorer gällande planering, design och implementering av hållbara urbana dagvattensystem i den bebyggda miljön.  Metoderna som användes var litteraturstudie och multipel fallstudie. Arbetet började med litteraturstudien och sedan genomfördes en fallstudie där fem områden som implementerat hållbara urbana dagvattensystem undersöktes. Lärdomar från varje område sammanställdes och kopplades samman med den andra litteraturen för att besvara forskningsfrågorna.  Utifrån litteraturen och fallstudierna sammanställdes rekommendationer för hur ett hållbart urbant dagvattensystem kan planeras och implementeras inom ett utvalt studieområde, vilket är Välsviken i Karlstad, Sverige.   För att åstadkomma ett hållbart och resilient urbant dagvattensystem, som kan hantera utmaningarna gällande klimatförändringar och urbanisering, är det viktigt att planeringsprocessen för dagvatten ändras. Det är viktigt att implementera anläggningar och system som är hållbara, multifunktionella och flexibla. Planeringsprocessen behöver använda planerings- och kostandsmetoder som inkluderar översvämningsanpassning och sidofördelar, både långsiktigt och kortsiktigt samtidigt. Man behöver också möjliggöra implementering av hållbara urbana dagvattensystem i nya områden eller anpassa områden som redan är bebyggda. Detta kan bidra till att skapa urbana områden som kan hantera klimatförändringarnas och urbaniseringens utmaningar, och skapa multifunktionella, hållbara och översvämningssäkrade områden.

The paper evaluates nature-based solutions for a retrofitting proposal for the combined regeneration, climate adaptation, and green space management of the industrial area Gåsebäck in Helsingborg, Sweden. The objective of this study was to evaluate options for how Gåsebäck could be sustainably regenerated and developed, while providing additional security against future negative effects of climate change, through the implementation of nature-based solutions. The methods used were unstructured interviews, literature study, thematic data analysis, and scoping review. Some urban societal challenges the area is facing were identified as Urban regeneration, Climate adaptation, and Green space management. The suggested NBSs to address these challenges are phytoremediation, mycoremediation, street trees and bushes, green walls, green roofs, flower beds, permeable surfaces, roadside greenery, rain gardens, de-culvertation and pocket parks. Examples of how the identified nature-based solutions can be retrofitted to block Italien are installing green walls on the old fire station for noise and pollution abatement, biodiversity increase, climate regulation, and enhancement of green elements; green roofs on various buildings for e.g. water management, increased biodiversity and green elements; street trees and bushes along the streets Södergatan and Malmöleden/Gåsebäcksvägen for noise and pollution abatement, water management, biodiversity increase, and enhancement of green elements; site specific installation or pocket park with phyto- or mycoremediation; flower beds and roadside traffic to increase attractiveness; and rain gardens and permeable surfaces for water management. / <p>20180620</p>

Le changement d’approche de la conservation de la nature est à l’oeuvre, et se manifeste aujourd'hui à travers des politiques fondées sur le concept scientifique de réseau écologique. Celui-ci est considéré comme l’expression du « troisième temps de la conservation », en ce qu’il vient compléter les approches antérieures de la nature, centrées prioritairement sur la création d’aires protégées. Le réseau écologique doit permettre de répondre plus efficacement aux enjeux de maintien de la biodiversité : il met l’accent sur le besoin d’établir des corridors entre les habitats naturels, afin de favoriser la mobilité et le brassage des populations animales et végétales. En France, la trame verte et bleue (TVB) est un nouvel objet politique publique qui concrétise cette approche dynamique de la conservation. La thèse porte sur le processus de territorialisation de la TVB, à travers une méthode par études de cas. L’objectif central de ce travail est d’examiner les effets de la TVB sur la mise en oeuvre de l’action publique, en considérant celle-ci comme un vecteur potentiel de changement des politiques de protection de la nature et/ou des politiques d’aménagement. Ces politiques sont respectivement étudiées aux échelles régionale et locale. / The change of approach in the conservation of nature is at work, embodied today by policies based on the scientific concept of ecological network. This concept is the expression of the "third step of conservation", complementing previous approaches, mainly focused on creating protected areas. The ecological network should provide better responses to the challenges of maintaining biodiversity: it emphasizes the need to set up bridges between natural environments, to stimulate mobility and mixing of plant and animal populations. In France, the green and blue infrastructure (TVB) is a new public policy entity, which materializes this dynamic approach to conservation. The thesis covers the process of territorialization of TVB, using a case study based methodology. The core of this work is to assess the effects of TVB on public policies, considering it a potential game changer in nature conservation policies and/or land-planning policies. These policies are studied at both regional and local scales.

Notwithstanding the environmental degradation that affects their watercourses, cities are also suffering the impacts of another relevant process that deteriorates the environmental quality, climate change. To face climate change, in addition to mitigation measures, it is imperative to adopt adaptation measures. Green and blue infrastructure are solutions that reconcile engineering, plant restoration and water quality maintenance, which add ecosystem services to the revitalization of urban drainage, and may include ecosystem-based adaptation measures. In this context, the general objective of the research is the revitalization of urban streams in the promotion of measures to adapt to climate change based on ecosystems (EbA), from the case of the Sape stream. With this, we add the specific objectives in order to characterize the activities of the revitalization process of Sapé stream as a green and blue infrastructure; To identify the ecosystem services associated with the revitalization process of Sapé stream; To analyze the ecosystem services associated with the urban and environmental improvements promoted in the revitalization process in relation to measures of EbA and to evaluate if the EBAs meet the recommended in the Adaptation Plan to climate change in the Ministry of the Environment (MMA). This research has a qualitative and exploratory purpose. The sources of evidence for the accomplishment of the case study refer to: bibliographic research, documentary research, field data collection and semi-structured interviews. The results were obtained through documental, bibliographic analysis and interviews analyzed by the software IRAMUTEQ, after a comparison of the literature with the EbA found in the place. Finally, it is concluded that the recognition that urban drainage revitalization programs lead to EbA measures can contribute to a more in-depth discussion of the scope of public programs that aim to reverse the current degradation of urban rivers. / A revitalização dos rios e córregos urbanos assume um papel relevante na busca pela sustentabilidade ambiental nas cidades. Não obstante o quadro de degradação ambiental que afeta seus cursos d´água, as cidades também vêm sofrendo os impactos de outro relevante processo que deteriora a qualidade ambiental, as mudanças climáticas. Para enfrentar as mudanças climáticas, além das medidas de mitigação, se faz premente a adoção de medidas de adaptação. Infraestrutura azul revelam-se soluções que conciliam medidas de engenharia, de recomposição vegetal e de manutenção da qualidade de água, que agregam serviços ecossistêmicos na revitalização de drenagens urbanas e podem abranger medidas de adaptação baseada em ecossistemas. Nesse contexto, insere-se o objetivo geral da pesquisa que consiste na revitalização de córregos urbanos quanto à promoção de medidas de adaptação a mudanças climáticas baseada em ecossistemas (AbE), a partir do caso do córrego do Sapé. Com isso soma-se os objetivos específicos a fim de caracterizar as atividades do processo de revitalização do córrego do Sapé enquanto infraestrutura verde e azul; identificar os serviços ecossistêmicos associados ao processo de revitalização do córrego do Sapé; analisar os serviços ecossistêmicos associados as melhorias urbanas e ambientais promovidas no processo de revitalização quanto a medidas de AbE e avaliar se as eventuais AbE atendem o preconizado no Plano de Adaptação à mudança do clima no Ministério do Meio Ambiente (MMA). Esta pesquisa tem caráter qualitativa e de objetivo exploratório. As fontes de evidências para consecução do estudo de caso referem-se a: pesquisa bibliográfica, pesquisa documental, levantamento de dados de campo e entrevistas semiestruturadas. Os resultados foram obtidos por meio da análise documental, bibliográfica e entrevistas analisadas pelo software IRAMUTEQ, após foi feito uma comparação da literatura com as AbE encontrada no local. Por fim conclui-se que o reconhecimento de que programas de revitalização de drenagens urbanas ensejam medidas de AbE permite contribuir para uma discussão mais aprofundada do alcance dos programas públicos que visam reverter o quadro de degradação atual dos rios urbanos.

One of the main challenges in promoting rainwater management into practise is the fact that it was not recognized as an interdisciplinary issue. We should seek ways how to open the problem to other professions, specially for architects and urban planners, who are the key element of its farther development. This work analyzes the reasons of this unsatisfactory state of rainwater management in the Czech Republic and it defines the possible ways how to remedy this state and outlines scenarios of its further development. The default document of the work is czech technical standard "TNV 75 9010 Hospodaření se srážkovými vodami". The new methodological guide, which is part of this work, is based on it. The work extends the range of measures which are mentioned in the standard. It brings new ways for assessing the benefits of the various measures to streamline the application of rainwater management measures in urban space.
