    Identifying degrees of deprivation from space using deep learning and morphological spatial analysis of deprived urban areas2022In: Computers, Environment and Urban Systems, ISSN 0198-9715, E-ISSN 1873-7587, Vol. 95, article id 101820Article in journal (Refereed)
    Abstract [en]

    Many cities in low- and medium-income countries (LMICs) are facing rapid unplanned growth of built-up areas, while detailed information on these deprived urban areas (DUAs) is lacking. There exist visible differences in housing conditions and urban spaces, and these differences are linked to urban deprivation. However, the appropriate geospatial information for unravelling urban deprivation is typically not available for DUAs in LMICs, constituting an urgent knowledge gap. The objective of this study is to apply deep learning techniques and morphological analysis to identify degrees of deprivation in DUAs. To this end, we first generate a reference dataset of building footprints using a participatory community-based crowd-sourcing approach. Secondly, we adapt a deep learning model based on the U-Net architecture for the semantic segmentation of satellite imagery (WorldView 3) to generate building footprints. Lastly, we compute multi-level morphological features from building footprints for identifying the deprivation variation within DUAs. Our results show that deep learning techniques perform satisfactorily for predicting building footprints in DUAs, yielding an accuracy of F1 score = 0.84 and Jaccard Index = 0.73. The resulting building footprints (predicted buildings) are useful for the computation of morphology metrics at the grid cell level, as, in high-density areas, buildings cannot be detected individually but in clumps. Morphological features capture physical differences of deprivation within DUAs. Four indicators are used to define the morphology in DUAs, i.e., two related to building form (building size and inner irregularity) and two covering the form of open spaces (proximity and directionality). The degree of deprivation can be evaluated from the analysis of morphological features extracted from the predicted buildings, resulting in three categories: high, medium, and low deprivation. The outcome of this study contributes to the advancement of methods for producing up-to-date and disaggregated morphological spatial data on urban DUAs (often referred to as 'slums') which are essential for understanding the physical dimensions of deprivation, and hence planning targeted interventions accordingly.

    A precise gravimetric geoid model in a mountainous area with scarce gravity data: a case study in central Turkey2012In: Studia Geophysica et Geodaetica, ISSN 0039-3169, E-ISSN 1573-1626, Vol. 56, no 4, p. 909-927Article in journal (Refereed)
    Abstract [en]

    In mountainous regions with scarce gravity data, gravimetric geoid determination is a difficult task that needs special attention to obtain reliable results satisfying the demands, e.g., of engineering applications. The present study investigates a procedure for combining a suitable global geopotential model and available terrestrial data in order to obtain a precise regional geoid model for Konya Closed Basin (KCB). The KCB is located in the central part of Turkey, where a very limited amount of terrestrial gravity data is available. Various data sources, such as the Turkish digital elevation model with 3 '' x 3 '' resolution, a recently published satellite-only global geopotential model from the Gravity Recovery and Climate Experiment satellite (GRACE) and the ground gravity observations, are combined in the least-squares sense by the modified Stokes' formula. The new gravimetric geoid model is compared with Global Positioning System (GPS)/levelling at the control points, resulting in the Root Mean Square Error (RMS) differences of +/- 6.4 cm and 1.7 ppm in the absolute and relative senses, respectively. This regional geoid model appears to he more accurate than the Earth Gravitational Model 2008, which is the best global model over the target area, with the RMS differences of +/- 8.6 cm and 1.8 ppm in the absolute and relative senses, respectively. These results show that the accuracy of a regional gravimetric model can be augmented by the combination of a global geopotential model and local terrestrial data in mountainous areas even though the quality and resolution of the primary terrestrial data are not satisfactory to the geoid modelling procedure.

    Determination of a gravimetric geoid model of Sudan using the KTH method2009Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    The main objective of this study is to compute a new gravimetric geoid model of Sudan

    using the KTH method based on modification of Stokes’ formula for geoid determination.

    The modified Stokes’ formula combines regional terrestrial gravity with long-wavelength

    gravity information provided by the global gravitational model (GGM). The collected

    datasets for this study contained the terrestrial gravity measurements, digital elevation

    model (DEM), GPS/levelling data and four global gravitational Models (GGMs), (EGM96,

    EIGEN-GRACE02S, EIGEN-GL04C and GGM03S).

    The gravity data underwent cross validation technique for outliers detection, three gridding

    algorithms (Kriging, Inverse Distance Weighting and Nearest Neighbor) have been tested,

    thereafter the best interpolation approach has been chosen for gridding the refined gravity

    data. The GGMs contributions were evaluated with GPS/levelling data to choose the best

    one to be used in the combined formula.

    In this study three stochastic modification methods of Stokes’ formula (Optimum, Unbiased

    and Biased) were performed, hence an approximate geoid height was computed. Thereafter,

    some additive corrections (Topographic, Downward Continuation, Atmospheric and Ellipsoidal)

    were added to the approximated geoid height to get corrected geoid height.

    The new gravimetric geoid model (KTH-SDG08) has been determined over the whole

    country of Sudan at 5′ x 5′ grid for area ( 4 ). The optimum method

    provides the best agreement with GPS/levelling estimated to 29 cm while the agreement for

    the relative geoid heights to 0.493 ppm. A comparison has also been made between the new

    geoid model and a previous model, determined in 1991 and shows better accuracy.

    􀁄 ≤φ ≤ 23􀁄 , 22􀁄 ≤ λ ≤ 38􀁄

    Keywords: geoid model, KTH method, stochastic modification methods, modified Stokes’ formula,

    additive corrections.

    City of the Dead - “We are neither living nor dying, we are something in between”2023Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    “We are neither living nor dying, we are something in between”

    Since the beginning of history, the living and the dead have been separated. This has made it almost im- possible to co-live together under one roof. We, ‘the living’, have even created “deathscapes” which have set a clear boundary between us and them, ‘the dead’. In every society, with its own cultural norms and rituals, they act with the dead in their own way - some are buried, others are burnt, but what is common across all societies is that they are not evident in our lives anymore. Looking at it from an urban perspective, the dead occupy a big patch of land in every city. This acts as a burden, as it makes “forbidden spaces” where the living is not able to be part of it.

    However, in each topic, there is a lesson that can be learned from it. In this case, it’s a 6km stretch informally and formally built, with a rich history and poor squatters who have no choice except to dwell with the dead. This is City of the Dead, located in Cairo, Egypt. The extreme lack of housing has pushed a part of society to live informally in cemeteries, where they have learned to co-live in the same room as the dead; they’ve embraced the idea of sleeping next to the dead, working and playing on those deathscapes.

    But ever since the government announced that they will demolish those deathscapes as a part of demolishing all informal settlements in Cairo, the time has come to make a stand against this decision, instead learning from their “life hack” and applying it throughout the City of the Dead – creating a society where the dead and living are not separated, maximizing the lost potentials in cases such as City of the Dead and making them not looked down upon and marginalized. This thesis aims to design the city and improve the lives of people living in these cemeteries, dealing with each case with care and compassion.

    Investigation and Comparison of 3D Laser Scanning Software Packages2012Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Laser scanning technologies has become an important tool in many engineering projects and applications. The output of laser measuring is the point cloud, which is processed in a way that makes it suitable for different applications. Processing of point cloud data is achieved through laser scanning software packages. Depending on the field of application, these packages have many different kinds of functions and methods that can be used. The main processing tasks used on a laser scanning software package include registration, modelling and texture mapping. Investigation and comparison of two laser scanning processing packages (Leica Cyclone and InnovMetric PolyWorks) are performed in this study. The theoretical and mathematical backgrounds of the above functions are presented and discussed. The available methods and functions used by each of the packages for these tasks are addressed and discussed. By using sample data, these functions are trailed and their results are compared and analyzed.

    The results from registration tests show the same results on both packages for the registration using target methods. Although, the results of cloud-to-cloud registration show some deviation from target registration results, they are more close to each other in both packages than to the target registration results. This indicates the efficiency of cloud-to-cloud methods in averaging the total registration error on all used points, unlike target registration methods.

    The modelling tests show more differences in the accuracy of generated models between the two packages. For both fitting and surface construction methods, PolyWorks showed better results and capabilities for three-dimensional modelling. As a result, the advantages and disadvantages of each package are presented in relation with the used task and methods, and a review of data exchange abilities is presented.

    Application of Molodensky's Method for Precise Determination of Geoid in Iran2011In: Journal of Geodetic Science, ISSN 2081-9919, E-ISSN 2081-9943, Vol. 1, no 3, p. 259-270Article in journal (Refereed)
    Abstract [en]

    Determination of the geoid with a high accuracy is a challenging task among geodesists. Its precise determination is usually carried out by combining a global geopotential model with terrestrial gravity anomalies measured in the region of interest along with some topographic information. In this paper, Molodensky's approach is used for precise determination of height anomaly. To do this, optimum combination of global geopotential models with the validated terrestrial surface gravity anomalies and some deterministic modification schemes are investigated. Special attention is paid on the strict modelling of the geoidal height and height anomaly difference. The accuracy of the determined geoid is tested on the 513 points of Iranian height network the geoidal height of which are determined by the GPS observations.

    Abstract [en]

    Sweden is one of the leading countries when it comes to availability in the physical environment. Approximately 7 000 children in Sweden are disabled. Half of these children use a wheelchair. It is every child’s right to play, and it’s thereby interesting to know whether every child is given the opportunity to use a playground. In the county of Helsingborg there are playgrounds appealing to many children, although the question is whether every child is given the chance to play at these playgrounds.

    The aim of this study is to highlight the importance of availability at playgrounds and outline ways to improve the availability. The method used in this thesis is a literature study, focusing on legal framework and literature about availability, usability and playgrounds. The case study provides information about eight playgrounds in Helsingborg. There is also an interview with landscape architect Johanna Elgström.

    Playgrounds where availability has been prioritized are often more available and useable for wheelchair-bound children. Still, the legal framework is in need of a more precise definition of availability and usability to ensure that playgrounds are suitable for children using a wheelchair. The playgrounds that are more available and useable can favor children using a wheelchair and give them the opportunity to socially interact with other children.

    Abstract [en]

    Since the 1st of January 2004 it has according to Swedish law been possible to form a 3D property. As the cities continue to grow and expand by attract more inhabitants it has become of a greater importance to develop the city and at the same time preserving its qualities. 3D property formation could be used to do so. This thesis focuses on 3D property formation where a facility is built underneath a public space. The thesis study how the responsibility to maintain the 3D property should be distributed between the property owners, in this case between the municipality and a private property owner, to establish a long term management of the public spplace as well as the underground construction. The research is carried out by studying property formation cases, detail plans and contracts. The results of the study shows that 3D property research is a highly complex matter and that a clear distribution of responsibilities between the property owners is requiredneeded in order to facilitate a long term management of the property. It is also important to distribute any eventual costs and clearly decide what responsibilities each property owner has. Lastly, collaboration between the divisions within the municipality as well as collaboration between the municipality and the department of cadastral survey is of great importance to secure that the information given in property formation cases, detail plans and contracts is unambiguous.

    Determinants of traveler satisfaction: Evidence for non-linear and asymmetric effects2019In: Transportation Research Part F: Traffic Psychology and Behaviour, ISSN 1369-8478, E-ISSN 1873-5517, Vol. 66, p. 339-356Article in journal (Refereed)
    Abstract [en]

    Classifying public transport service attributes based on their influence on overall traveler satisfaction can assist stakeholders and practitioners in introducing cost-efficient measures. To date most studies employed methods that were based on the assumption that the impact of service attributes on traveler satisfaction is entirely linear and symmetric. This study examines whether service attributes have a non-linear and asymmetric influence on the overall travel experience by employing the Three-factor theory (basic, performance and exciting factors). The analysis is conducted for different traveler segments depending on their level of captivity, travel frequency by public transport and travel mode used, and is based on a relatively large sample size collected for Stockholm County. Moreover, the estimated models control for important socio-demographic and travel characteristics that have been insofar overlooked. Results are presented in the form of a series of multi-level cubes that represent different essentiality of traveler needs which provide a useful methodological framework to further design quality service improvements that can be applied to various geographical contexts. Our findings highlight that a “one size fits all” approach is not adequate for identifying the needs of distinct traveler segments and of travelers using different travel modes. Furthermore, two-thirds of the attributes are consistently classified into the same factor category which entails important policy implications. This research deepens and expands the very limited knowledge of the application of the three-factor theory in the transport field.

    How does travel satisfaction sum up?: Decomposing the door-to-door experience for multimodal trips2018In: Transportation, ISSN 0049-4488, E-ISSN 1572-9435, Vol. 46, no 5, p. 1615-1642Article in journal (Other academic)
    Abstract [en]

    Understanding how satisfaction with individual trip legs aggregates to the overall travel experience for different types of trips will enable the identification of the trip legs that are most impactful. For this purpose we analyze data on retrospective evaluations of entire multi-modal trip experiences and satisfaction with individual trip legs. We formulate and describe alternative aggregation rules and underpin them in theory and previous empirical findings. The results of a series of regression models show that for a large number of multi-modal trip configurations normative rules can better reproduce overall travel satisfaction than heuristic rules. This indicates that all trip legs need to be considered when evaluating the overall travel experience, especially for trips legs involving waiting and/or transferring time. In particular, weighting satisfaction with individual trip legs with perceived trip leg durations yielded the best predictor of overall travel satisfaction. No evidence for a disproportional effect of the last or most exceptional part of the trip was found. This research contributes to the literature on combining multi-episodic experiences and provides novel empirical evidence in the transport domain.

    Individual, Travel, and Bus Stop Characteristics Influencing Travelers’ Safety Perceptions2018In: TRR Journal of transportation research board, ISSN 0361-1981Article in journal (Refereed)
    Abstract [en]

    Ensuring safety during door-to-door public transport trips is a fundamental challenge to service providers as safety influences individuals’ mobility. Using reported safety perceptions of travelers waiting at six bus stops with different characteristics in Stockholm, this study investigates factors that have an impact on determining travelers’ perceived safety and crime perceptions. This is done by assessing the importance of real-time information provision and the environmental characteristics of bus stops during the day and at night for different types of crime, after controlling for travelers’ individual and trip characteristics, and their previous experiences of victimization. Interaction effects of age, gender, and travel frequency are also tested. The  results  suggest  that  bus  shelter  characteristics,  natural  surveillance,  and  trustworthy  real-time  information  are  the most important factors influencing safety and crime perceptions. Additionally, safety perceptions are strongly influenced by previous experiences of victimization. The effect of perceived feelings about crime and safety are found to be nuanced by age and gender. Unlike some common beliefs, travelers: (1) feel less worried about becoming a victim of crime at bus stops associated with high crime rates; (2) prefer opaque shelters at night; and (3) have higher safety perceptions when the stop is located in an area of mixed land use. The impact of a bus stop’s number of passers-by is found to be insignificant. No direct or indirect effects can be attributed to frequency of travel by bus, indicating that familiar places and routine behavior have noeffect on declared crime and safety perceptions.

    What is the role of weather, built-environment and accessibility geographical characteristics in influencing travelers’ experience?2019In: Transportation Research Part A: Policy and Practice, ISSN 0965-8564, E-ISSN 1879-2375, Vol. 122, p. 34-50Article in journal (Refereed)
    Abstract [en]

    We examine the effect of weather, accessibility and built-environment characteristics on overall travel experience as well as the experience with the latest trips. These are factors that are often disregarded in the travel satisfaction literature even though they are believed to largely influence the first mile of the door-to-door trip. This study fills a research gap in investigating all these factors by using, amongst other, a relatively large travel satisfaction survey from years 2009 to 2015 and by focusing on urban and peri-urban geographical contexts, the city and county of Stockholm (Sweden), respectively. The ordered logit model results show that county dwellers living close to a metro station and in well linked-to-all areas report higher overall travel satisfaction evaluations. In addition, precipitation and ground covered with snow have a negative influence on travel satisfaction. Our findings indicate that built-environment characteristics exert a rather weak influence on the travel experience, especially in the peri-urban context. However, some aspects such as living in areas with medium densities, low income and with high safety perceptions around public transport stations are associated with higher satisfaction levels. In turn, areas with single land uses are found to have lower travel satisfactions. These results are important for public transport planners and designers in devising measures to prevent and mitigate the negative outcome of some weather conditions and to conceive better designed transit oriented developments.

    Assessing the threats against rural Sweden: An exploration of crimes against Swedish farmers related to animal production2020Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In the discourse of crime and place, the focus has rarely fallen on rural crime. While experiencing comparably lower crime levels than urban counterparts, the common association with rural areas as being symbols of peace and friendly social interaction is not necessarily accurate. One group that often are thought of as inherently rural is farmers, who’s workplaces may possess certain unique vulnerabilities to crime compared to other locations. This thesis aims to obtain a better understanding of the threats against farmers related to animal production in a Swedish context, adding to the knowledge base regarding rural crime and sustainable development of rural and urban areas. The objectives of the study are:

    • to investigate the nature of the victimization of farmers devoted to animal production in Sweden, especially related the situational conditions of farms and rural areas.

    • to explore new data that could be used to approximate the scale of the threats against farmers using data from media archives from 2009 to 2019. This study reports types, frequency, and location of crimes against animal production with a focus on mink, rabbit and pig farms. Geographical Information Systems (GIS) is used to report the geography of these offences at municipal level. The theories of the routine activity approach and situational crime prevention are used to try to explain certain conditions that may facilitate crime on farms, while the offenders are explored using the theory on techniques of neutralization.

    The findings of the study show that the experience of the chosen actor’s varied greatly, but with crimes such as trespassing, vandalism and theft being common types of offenses across the board. The locations of the crime events were focused in the southern to mid of Sweden. Situational conditions that may have facilitated crime includes: the large size of farms and low population density providing low detection of crime, high value targets, and relatively high accessibility to the farms. From the data, mainly three techniques of neutralization were observed to be utilized: denial of the victim, denial of injury and appeal to higher loyalties. Multiple techniques were observed to be utilized together, while simultaneously exploiting situational conditions to facilitate the neutralization.

    Crime and safety in rural areas: A systematic review of the English-language literature 1980-20202022In: Journal of Rural Studies, ISSN 0743-0167, E-ISSN 1873-1392, Vol. 94, p. 250-273Article, review/survey (Refereed)
    Abstract [en]

    This article explores the nature and frequency of crimes and people's safety perceptions in rural areas using a systematic review of the literature. It explores four decades of English-language publications on crime and safety in rural areas from several major databases; mainly Scopus, JSTOR and ScienceDirect. The number of retrieved documents was 840, of which 410 were selected for in-depth analysis and their topics later categorized by theme. We found that rural crime research took off after the mid-1980s and experienced an increase during the 2010s. Despite the domination by North American, British and Australian scholarship, studies from other parts of the world (including the Global South) are increasingly being published as well. Publications on rural crime patterns (e.g., farm crime) compose over one-fifth of the reviewed literature. This together with rural policing/criminal justice and violence constitute the three largest themes in rural criminology research. With ever-increasing links between the local and the global, this review article advocates for tailored multilevel responses to rural crimes that, more than ever, are generated by processes far beyond their localities.

    Naturens roll i ett digitaliserat Stockholm2020Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    In recent years, the term “smart city” has been increasingly used to describe a future sustainable city (Colding & Barthel, 2017). Social, economic, and ecological sustainability is expected to be achieved by using digital technology. At the same time, it is considered important that people switch to more sustainable lifestyles in order to reduce the human impact on the climate (National Research Council, 1999). Studies have shown that nature experiences have the potential to increase the environmental commitment (Kals mfl., 1999; Ballantyne & Packer, 2009). Digital technology is considered to have great potential for facilitating interactions with nature, thereby strengthening the nature-human connection (Maffey mfl., 2015). At the same time, digital technology may increase the distance between man and nature. The current digitalization process is reflected in the Smart City vision in Stockholm. Furthermore, the Swedish outdoor life is considered to be more and more commercialized (Margaryan, 2017; Margaryan & Fredman, 2017). This study is based on two issues, of which the first relates to how digital technology can affect the relationship between humans and nature. The second issue relates to the conceptions of nature that underpin people’s interpretations of it. The study aims to investigate what potential digital tools can be considered to use to promote increased sustainability as well as what views of nature that can be identified among the outdoor life sector in Stockholm. In order to achieve the aim of the study, a qualitative method with a literature study as well as semi-structured interviews has been used. The digital innovation Outdoor Map will constitute a case study. The results show that nature experiences can be related to increased environmental commitment by increasing the interest in nature as well as the human-nature connection. Digital services can help promote people’s contact with nature by constituting additional sources for information about nature areas, as well as increasing the satisfaction of nature experiences. Much of the potential of the Outdoor Map seems to be related to the long-term expansion as it has a connection with the collaboration structure that underpins the service as well as the social community which is an important advantage of the service. Digital tools should be considered as having the potential to promote nature stays for those who otherwise rarely experience nature by providing information and by being available on the smartphone. At the same time, these types of services may have difficulty reaching those who do not usually involve themselves in nature. Furthermore, the study indicated that different views of nature can be activated in different situations. Different views of nature seemed to be activated when the respondents discussed the benefits of nature experiences compared to when the discussions concerned the human-nature relationship. This can be explained by differences between personal attitudes and the tactics used to promote sustainability. Based on the results of the study, it is proposed to include a reflection in the outdoor life sector about how nature is talked about and how it is presented.

    Vild natur: Värden, attityder och associationer2017Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Modern humans are considered to have lost connection to nature and actions to reduce the separation between man and nature has been demanded. Green areas are often valued from a broad perspective and few studies have investigated the specific nature of the wild habitat. There also seem to be definitive problems and conflicts regarding the concept of "wild nature". The purpose of this report is to identify the specific values of wild nature ​​and to investigate what the concept really can include. Another purpose is to investigate attitudes and associations to wild nature and how wild nature is being worked on in planning.

    A literature study has been used as the primary method. The literature study has been supplemented with a minor case study including a documentary study, interviews and questionnaires.

    The conclusion is that wild nature offers values ​​of ecological, educational and experiential character. The ecological value is that wild nature allows biodiversity. The educational value includes aspects that help strengthen the connection to nature, which may lead to changed environmental behavior. Wild nature also has values ​​that concerns for example the experience of spiritual and reflective emotions, contributing to stress reduction and increased well-being. Moreover, wild nature is associated with large areas unaffected by humans. The same approaches are in the planning process, and the experience of wild nature is often evaluated from an ecological perspective. This means that the potential of green spaces that does not fit into the traditional image is not taken advantage of. Wild nature can also be defined based on the experience qualities related to wildness. A development towards such an approach could mean that the specific nature of the wild nature is taken advantage of. This could contribute to the increased well-being of the residents, but in the long term, a more sustainable society.

    Recovering Moho parameters using gravimetric and seismic data2016Doctoral thesis, comprehensive summary (Other academic)
    Abstract [en]

    Isostasy is a key concept in geoscience to interpret the state of mass balance between the Earth’s crust and mantle. There are four well-known isostatic models: the classical models of Airy/Heiskanen (A/H), Pratt/Hayford (P/H), and Vening Meinesz (VM) and the modern model of Vening Meinesz-Moritz (VMM). The first three models assume a local and regional isostatic compensation, whereas the latter one supposes a global isostatic compensation scheme.

    A more satisfactory test of isostasy is to determine the Moho interface. The Moho discontinuity (or Moho) is the surface, which marks the boundary between the Earth’s crust and upper mantle. Generally, the Moho interface can be mapped accurately by seismic observations, but limited coverage of seismic data and economic considerations make gravimetric or combined gravimetric-seismic methods a more realistic technique for imaging the Moho interface either regional or global scales.

    It is the main purpose of this dissertation to investigate an isostatic model with respect to its feasibility to use in recovering the Moho parameters (i.e. Moho depth and Moho density contrast). The study is mostly limited to the VMM model and to the combined approach on regional and global scales. The thesis briefly includes various investigations with the following specific subjects:

    1) to investigate the applicability and quality of satellite altimetry data (i.e. marine gravity data) in Moho determination over the oceans using the VMM model, 2) to investigate the need for methodologies using gravimetric data jointly with seismic data (i.e. combined approach) to estimate both the Moho depth and Moho density contrast over regional and global scales, 3) to investigate the spherical terrain correction and its effect on the VMM Moho determination, 4) to investigate the residual isostatic topography (RIT, i.e. difference between actual topography and isostatic topography) and its effect in the VMM Moho estimation, 5) to investigate the application of the lithospheric thermal-pressure correction and its effect on the Moho geometry using the VMM model, 6) Finally, the thesis ends with the application of the classical isostatic models for predicting the geoid height.

    The main input data used in the VMM model for a Moho recovery is the gravity anomaly/disturbance corrected for the gravitational contributions of mass density variation due in different layers of the Earth’s crust (i.e. stripping gravity corrections) and for the gravity contribution from deeper masses below the crust (i.e. non-isostatic effects). The corrections are computed using the recent seismic crustal model CRUST1.0.

    Our numerical investigations presented in this thesis demonstrate that 1) the VMM approach is applicable for estimating Moho geometry using a global marine gravity field derived by satellite altimetry and that the possible mean dynamic topography in the marine gravity model does not significantly affect the Moho determination, 2) the combined approach could help in filling-in the gaps in the seismic models and it also provides good fit to other global and regional models more than 90 per cent of the locations, 3) despite the fact that the lateral variation of the crustal depth is rather smooth, the terrain affects the Moho result most significantly in many areas, 4) the application of the RIT correction improves the agreement of our Moho result with some published global Moho models, 5) the application of the lithospheric thermal-pressure correction improves the agreement of VMM Moho model with some other global Moho models, 6) the geoid height cannot be successfully represented by the classical models due to many other gravitational signals from various mass variations within the Earth that affects the geoid.

    Towards the Moho depth and Moho density contrast along with their uncertainties from seismic and satellite gravity observations2017In: Journal of Applied Geodesy, ISSN 1862-9016, E-ISSN 1862-9024, Vol. 11, no 4, p. 231-247Article in journal (Refereed)
    Abstract [en]

    We present a combined method for estimating a new global Moho model named KTH15C, containing Moho depth and Moho density contrast (or shortly Moho parameters), from a combination of global models of gravity (GOCO05S), topography (DTM2006) and seismic information (CRUST1.0 and MDN07) to a resolution of 1 degrees x 1 degrees based on a solution of Vening Meinesz-Moritz' inverse problem of isostasy. This paper also aims modelling of the observation standard errors propagated from the Vening Meinesz-Moritz and CRUST1.0 models in estimating the uncertainty of the final Moho model. The numerical results yield Moho depths ranging from 6.5 to 70.3 km, and the estimated Moho density contrasts ranging from 21 to 650 kg/m(3), respectively. Moreover, test computations display that in most areas estimated uncertainties in the parameters are less than 3 km and 50 kg/m(3), respectively, but they reach to more significant values under Gulf of Mexico, Chile, Eastern Mediterranean, Timor sea and parts of polar regions. Comparing the Moho depths estimated by KTH15C and those derived by KTH11C, GEMMA2012C, CRUST1.0, KTH14C, CRUST14 and GEMMA1.0 models shows that KTH15C agree fairly well with CRUST1.0 but rather poor with other models. The Moho density contrasts estimated by KTH15C and those of the KTH11C, KTH14C and VMM model agree to 112, 31 and 61 kg/m(3) in RMS. The regional numerical studies show that the RMS differences between KTH15C and Moho depths from seismic information yields fits of 2 to 4 km in South and North America, Africa, Europe, Asia, Australia and Antarctica, respectively.

    Combined Moho parameters determination using CRUST1.0 and Vening Meinesz-Moritz model2015In: Journal of Earth Science, ISSN 1674-487X, E-ISSN 1867-111X, Vol. 26, no 4, p. 607-616Article in journal (Refereed)
    Abstract [en]

    According to Vening Meinesz-Moritz (VMM) global inverse isostatic problem, either the Moho density contrast (crust-mantle density contrast) or the Moho geometry can be estimated by solving a non-linear Fredholm integral equation of the first kind. Here solutions to the two Moho parameters are presented by combining the global geopotential model (GOCO-03S), topography (DTM2006) and a seismic crust model, the latter being the recent digital global crustal model (CRUST1.0) with a resolution of 1A(0)x1A(0). The numerical results show that the estimated Moho density contrast varies from 21 to 637 kg/m(3), with a global average of 321 kg/m(3), and the estimated Moho depth varies from 6 to 86 km with a global average of 24 km. Comparing the Moho density contrasts estimated using our leastsquares method and those derived by the CRUST1.0, CRUST2.0, and PREM models shows that our estimate agrees fairly well with CRUST1.0 model and rather poor with other models. The estimated Moho depths by our least-squares method and the CRUST1.0 model agree to 4.8 km in RMS and with the GEMMA1.0 based model to 6.3 km.

    Modelling Moho depth in ocean areas based on satellite altimetry using Vening Meinesz–Moritz’ method2016In: Acta Geodaetica et Geophysica Hungarica, ISSN 1217-8977, E-ISSN 1587-1037, Vol. 51, no 2, p. 137-149Article in journal (Refereed)
    Abstract [en]

    An experiment for estimating Moho depth is carried out based on satellite altimetryand topographic information using the Vening Meinesz–Moritz gravimetric isostatichypothesis. In order to investigate the possibility and quality of satellite altimetry in Mohodetermination, the DNSC08GRA global marine gravity field model and the DTM2006 globaltopography model are used to obtain a global Moho depth model over the oceans with aresolution of 1 x 1 degree. The numerical results show that the estimated Bouguer gravity disturbancevaries from 86 to 767 mGal, with a global average of 747 mGal, and the estimatedMoho depth varies from 3 to 39 km with a global average of 19 km. Comparing the Bouguergravity disturbance estimated from satellite altimetry and that derived by the gravimetricsatellite-only model GOGRA04S shows that the two models agree to 13 mGal in root meansquare (RMS). Similarly, the estimated Moho depths from satellite altimetry andGOGRA04S agree to 0.69 km in RMS. It is also concluded that possible mean dynamictopography in the marine gravity model does not significantly affect the Moho determination.

    The spherical terrain correction and its effect on the gravimetric-isostatic Moho determination2016In: Geophysical Journal International, ISSN 0956-540X, E-ISSN 1365-246X, Vol. 204, no 1, p. 262-273Article in journal (Refereed)
    Abstract [en]

    In this study, the Moho depth is estimated based on the refined spherical Bouguer gravity disturbance and DTM2006 topographic data using the Vening Meinesz-Moritz gravimetric-isostatic hypothesis. In this context, we compute the refined spherical Bouguer gravity disturbances in a set of 1 degrees x 1 degrees blocks. The spherical terrain correction, a residual correction to each Bouguer shell, is computed using rock heights and ice sheet thicknesses from the DTM2006 and Earth2014 models. The study illustrates that the defined simple Bouguer gravity disturbance corrected for the density variations of the oceans, ice sheets and sediment basins and also the non-isostatic effects needs a significant terrain correction to become the refined Bouguer gravity disturbance, and that the isostatic gravity disturbance is significantly better defined by the latter disturbance plus a compensation attraction. Our study shows that despite the fact that the lateral variation of the crustal depth is rather smooth, the terrain affects the result most significantly in many areas. The global numerical results show that the estimated Moho depths by the simple and refined spherical Bouguer gravity disturbances and the seismic CRUST1.0 model agree to 5.6 and 2.7 km in RMS, respectively. Also, the mean value differences are 1.7 and 0.2 km, respectively. Two regional numerical studies show that the RMS differences between the Moho depths estimated based on the simple and refined spherical Bouguer gravity disturbance and that using CRUST1.0 model yield fits of 4.9 and 3.2 km in South America and yield 3.2 and 3.4 km in Fennoscandia, respectively.

    Modelling Moho parameters and their uncertainties from the combination of the seismic and satellite gravity dataManuscript (preprint) (Other academic)
    Abstract [en]

    We present a method for estimating a new global Moho model (KTH15C), containing Moho depth and density contrast, from a combination of global models of gravity (GOCO05S), topography (DTM2006) and seismic information (CRUST1.0 and MDN07) to a resolution of 1°×1° based on a solution of Vening Meinesz-Moritz’ inverse problem of isostasy. Particularly, this article has its emphasis on the modelling of the observation standard errors propagated from the Vening Meinesz-Moritz and CRUST1.0 models in estimating the uncertainty of the final Moho model. The numerical results yield Moho depths ranging from 6.5 to 70.1 km, with a global average of 23.4 ± 13 km. The estimated Moho density contrasts range from 21 to 680 kg/m3, with a global average of 345.4 ± 112 kg/m3. Moreover, test computations display that in most areas estimated uncertainties in the parameters are less than 3 km and 50 kg/m3, respectively, but they reach to more significant values under Gulf of Mexico, Chile, Eeastern Mediterranean, Timor sea and parts of polar regions. Comparing the Moho depths estimated by KTH15C and those derived by KTH11C, GEMMA2012C, CRUST1.0, KTH14C, CRUST14 and GEMMA1.0 models shows that KTH15C agree fairly well with CRUST1.0 but rather poor with other models. The Moho density contrasts estimated by KTH15C and those of the KTH11C and KTH14C model agree to 120 and 80 kg/m3 in RMS. The regional numerical studies show that the RMS differences between KTH15C and Moho depths from seismic information yields fits of 2 to 4 km in South and North America, Africa, Europe, Asia, Australia and Antarctica, respectively.

    Interaction between rivers and morphology of cities in Sweden2014In: Our common future in urban morphology, Porto: FEUP edições (Faculdade de Engenharia da Universidade do Porto Edicoes), 2014Conference paper (Refereed)
    Abstract [en]

    Rivers as one of the most important topographic factor have played a strategic role not only on the appearance of cities but they also affect the structure and morphology of cities. In this paper I intend to find out the influence of rivers on the morphology of a cities and discuss that how a city in its physical network interacts with a river flowing inside. My study area is river-cities in Sweden in which they have not received much attention in this issue. To this purpose I use space syntax method integrating with geospatial analysis and extract the properties of physical form of cities in terms of global and local integration value, choice value and so on. Comparing the states of presence and absence of rivers in these cities as well as evaluating the effect of rivers on the morphology of areas located in different banks of rivers are also part of interest in this paper. The primary result shows that although a river is not comparable to a city based on size and the area occupied by, it has a significant effect on the form of a city in both global and local properties. In addition, tracking the pattern of river-cities and their interaction to rivers may lead us to interoperate the physical form of these cities in terms of structured and distributed cities.

    Resilience, space syntax and spatialinterfaces: The case of river cities2017In: A|Z ITU Journal of the Faculty of Architecture, ISSN 1303-7005, Vol. 14, no 1, p. 25-41Article in journal (Refereed)
    Abstract [en]

    Resilience defined as the capacity of a system to manage impacts, keep its efficiency and continue its development has been scrutinized by researchers from different points of view over the past decades. Due to the prominence of resilience in urban planning, this paper intends to find out how the spatial structure of cities deals with disturbances, and if geographical phenomena such as rivers affect the resilience in cities. Using the space syntax methods syntactically analyze the resilience in cities, we innovatively introduce two measures; similarity and sameness. These measures are in relation with the syntactical properties of cities and compare the degree of resilience between different groups. Similarity measures the degree to which each city retains the relative magnitude of its foreground network after a disturbance and sameness is the degree to which each city retains the same segments as its foreground network after a disturbance. Likewise to network resilience studies, we apply different disturbances on cities and explore the reaction of cities to disturbances in terms of size of the foreground network and which segments are parts thereof. We then compare different groups based on these measurements as a method to analyze sameness and similarity. The results show that the resilience, in the way we define it, is different in different cities depending on in which view and based on which parameters we are discussing the resilience. Additionally morphological phenomena such as rivers have a great impact on the structure of cities and in turn on their resilience.

    Rivers as integration devices in cities2016In: City, Territory and Architecture, E-ISSN 2195-2701, Vol. 3, no 1, p. 1-21Article in journal (Refereed)
    Abstract [en]

    Background: As dynamic systems rivers and cities have been in interaction under changing relations over time, and the morphology of many cities has risen through a long and steady struggle between the city functions and the river system flowing inside. This makes river cities an interesting case to study how the presence of geographical features interacts with spatial morphology in the formation of cities.

    Methods: The basis of this research is enabled by utilizing a novel model for cross-city comparison presented by Hillier in his Santiago keynote in 2012 called a “star model”. This is done on large samples of cities investigating concurrent configurations, as well as how the properties in this star model react to specific forms of disturbance.

    Results: Results illustrate that the foreground network as identified through maximum choice values in cities are more vital to the structure of cities than the bridges. The overall syntactic structure tends to retain its character (degree of distributedness) and the location of its foreground network (which street segments constitute the foreground network) even when bridges are targeted. Furthermore, counter to the initial hypothesis, river cities tend to change less than non-river cities after targeted disturbance of the systems. Finally, the results show that while there is a statistical morphological difference between river cities and non-river cities, this difference is not directly explained through the bridges.

    Conclusion: Integrating space syntax with statistical and geospatial analysis can throw light on the way in which the properties of city networks and urban structure reflect the relative effect of rivers on the morphology of river cities. The paper, finally, contributes through offering one piece of a better perception of the structure of river-cities that can support strategies of river-cities interaction as well as enhance our knowledge on the constraints and limits to that interaction.

    Visibility Analysis, Similarity and Dissimilarity in General Trends of Building Layouts and their Functions2013In: Proceedings of Ninth International Space Syntax Symposium / [ed] Young Ook Kim, Hoon Tae Park, Kyung Wook Seo, Seoul: Sejong University Press , 2013, p. 11:1-11:15Conference paper (Refereed)
    Abstract [en]

    Visibility analysis is one of the key methods in space syntax theory that discusses visual information conveyed to observers from any location in space that is potentially directly visible for the observer without any obstruction. Visibility – simply defined as what we can see – not only affects the spatial function of buildings, but also has visual relation to the perception of buildings by inhabitants and visitors. In this paper we intend to present the result of visibility analysis applied on a sample of building layouts of different sizes and functions from a variety of places of periods. The main aim of this paper is to statistically explore the general trends of building layouts and show if and how visibility properties such as connectivity, clustering coefficient, mean depth, entropy, and integration values can make distinctions among different functions of buildings. Our findings reveal that there are significant correlation coefficients among global properties of visibility in which we consider the mean value of properties, a similarity suggesting that they are not intensively manipulated by architecture. On the other hand, there are correlations although less so than the previous, still significant among local properties of visibility in which we consider the (max-min) value of properties, suggesting that social, cultural or other physical parameters distinguish buildings individually. We also show that functions such as ‘museum’ and ‘veterinary’ are relatively well-clustered, while functions such as ‘ancient’ and ‘shopping’ show high diversity. In addition, using a decision tree model we show that, in our sample, functions such as ‘museum’ and ‘library’ are more predictable rather than functions such as ‘hospital’ and ‘shopping.’ All of these mean that – at least in our sample – the usability and applicability of well-clustered and well-predicted functions have been predominant in shaping their interior spaces; vice versa, in well-diverse and unpredicted functions, the pragmatic solutions of people’s daily life developed in material culture affect the visual properties of their interior spaces.

    Flood hazard and its impact on the resilience of cities: An accessibility-based approach to amenities in the city of Gothenburg, Sweden2017In: Proceedings - 11th International Space Syntax Symposium, SSS 2017, Instituto Superior Tecnico, Departamento de Engenharia Civil, Arquitetura e Georrecursos , 2017, p. 36.1-36.15Conference paper (Refereed)
    Abstract [en]

    In the wake of climate change and its impact on increasing the number and intensity of floods, adaptability of cities to and resistance against the flood hazard is critical to retain functionality of the cities. Vulnerability of urban infrastructure and its resilience to flooding from different points of view have been important and worth investigating for experts in different fields of science. Flood hazards as physical phenomena are influenced by form of the cities and thus the magnitude of their impacts can be intensified by urban infrastructures such as street networks and buildings (Bacchin et. al, 2011). In this paper, we aim to develop a method to assess the resilience of a river city (the city of Gothenburg in Sweden), which is prone to flood events, against such disturbances and find out how the city reacts to river floods and to what extent the city retains its accessibility to essential amenities after a flood occurs. To do so, collecting required data; we, firstly, simulate flood inundation with two different return periods (50 and 1000 years) and then the impact areas overlay on the street networks. Evaluating the resilience of the city, syntactic properties of the street networks before and after flooding are measured at different scales. Additionally, accessibility and the minimum distance of the street networks to essential amenities such as healthcare centers, schools and commercial centers, at a medium distance (3 Km) is examined. The results show that flooding influences the city configuration at global scale more than the local scale based on comparison of syntactic properties before and after flooding. However, the results of accessibility and the minimum distance show that the impact of flooding on the functionality of the city is more limited to the riparian areas and the city is not affected globally.

    Flood Resilient Cities: A Syntactic and Metric Novel on Measuring the Resilience of Cities against Flooding, Gothenburg, Sweden2017In: Journal of Geographic Information System, ISSN 2151-1950, E-ISSN 2151-1969, Vol. 9, p. 505-534Article in journal (Refereed)
    Abstract [en]

    Flooding is one of the most destructive natural disasters which have rapidly been growing in frequency and intensity all over the world. In this view, assessment of the resilience of the city against such disturbances is of high necessity in order to significantly mitigate the disaster effects of flooding on the city structures and the human lives. The aim of this paper is to develop a method to assess the resilience of a river city (the city of Gothenburg in Sweden), which is prone to flood Hazard, against such disturbances. By simulating flood inundation with different return periods, in the first step, the areas of impact are determined. To assess the resilience, two different methods are followed. One is a syntactic method grounded in the foreground network in space syntax theory and the other is based on measuring accessibility to the essential amenities in the city. In the first method, similarity and sameness parameters are defined to quantitatively measure the syntactic resilience in the city. In the next step, accessibility to amenities and the minimum distance to amenities before and after each disturbance is measured. The results, in general, show that such disturbances affect the city structure and the resilience of the city differently. For instance, the city is more resilient after flooding ac- cording to accessibility measures. This clearly means that the answer to the question of resilience is mainly dependent on “resilience of what and for what.”

    Quantification of temporal changes in metal loads – Moss data over 20 years2007Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Environmental monitoring, assessment and conservation programmes worldwide have led to the development of scientific and technological methods to study the changes in our environment. As a result, a technique for monitoring atmospheric metal deposition was developed in Sweden in the 1960s. This technique is based on the principle that, carpet-forming moss obtains its nutrients from dry deposition particles in the air. The Swedish Environmental Research institute (IVL) has a database of concentrations of metals in terrestrial mosses. These were sampled during the national moss surveys (1975 – 2000). From these point data, long-term changes in the deposition loads can be studied.One aim of this project is to create continuous surfaces for these point data and to develop a technique to map the spatio-temporal changes. It also seeks to quantify the temporal changes in metal loads of the moss data for over 20 years. With the amount of data increasing from various air quality assessments and monitoring methods, it is prudent to approach the data analysis from a multidisciplinary perspective. By using statistics, geostatistic, GIS and visualization methods, the quantitative, spatial and temporal trends of the moss surveys were analysed. Multidimensional visualizations based on exploratory data analysis were applied to the data to visualize and reveal trends in the multivariate data.The project area comprised the whole Sweden with the data from 1975 to 2000, with the exception of the moss survey in 1975, which was conducted only in southern Sweden. A combination of GIS, geostatistics and high dimensional visualization techniques were applied in the data cleaning and analysis stages.The results of the project show the rate of change of metal loads over the years and the spatial distribution of the metal depositions as well. The visual approach used from the data cleaning to results presentation makes it easily comprehensible to non-scientist as well.

    Greening cities through urban planning: A literature review on the uptake of concepts and methods in Stockholm2022In: Urban Forestry & Urban Greening, ISSN 1618-8667, E-ISSN 1610-8167, p. 127584-Article in journal (Refereed)
    Abstract [en]

    Nature-based solutions (NBS) represent the most recent of several "greening" concepts proposed to support spatial planning and decision-making towards sustainable metropolitan regions. Despite similarities, the concepts stem from different disciplines and policy arenas and reflect various models of people-nature relations. This paper aims to analyze the uptake of greening concepts in scientific planning literature focusing on (urban) nature and landscape in the metropolitan region of Stockholm, Sweden, over the last three decades. It investigates what changes this evolution has brought in terms of the topics adopted, methods applied, and types of planning support put into practice. We identified 574 articles that reflect substantial research on greening concepts in the Swedish planning context. The articles demonstrate an initial prevalence of biodiversity with later increases of interest in ecosystem services and NBS. A detailed analysis of the studies focusing on Stockholm revealed Population growth/densification, Green space management and Biodiversity conservation as the most commonly addressed societal challenges. The most frequently mentioned type of green and blue element is Parks and (semi-)natural urban green areas, including urban forests. Methods applied were mostly quantitative, while mixes with qualitative approaches were only apparent in ecosystem services articles. Half of the studies involved practitioners or decision-makers, but only four seemed related to real-life planning processes. Taken together, the influence of scientific literature on the uptake of greening concepts in spatial planning seems to have been limited. Future mainstreaming of greening concepts in Stockholm and beyond could benefit from available data, methods and experiences, but will require more active translation and boundary management. Further research into science-policy-planning interfaces at city scale is thus imperative to advance more sustainable pathways for people and nature in metropolitan regions.

    An Operational Approach for Watershed Investments2020In: Ecosystem Services for Urban Water Security: Concepts and Applications in Sub-Saharan Africa, Cham: Springer Nature , 2020Chapter in book (Refereed)
    Abstract [en]

    This chapter focuses on Watershed Investments for securing water for cities. It starts with a brief account of the application of ecosystem services for decision-making and a theoretical background of boundary work. Accordingly, it proposes an operational approach developed for designing and assessing impact of watershed iInvestments to secure water for cities. The developed approach distin- guishes between a “strategic” and a “technical” component. The strategic component identifies as key inputs of the process of Watershed Investment design and assess- ment, the definition of objectives and visioning of feasible and desirable scenarios by stakeholders. The technical component applies spatially explicit modelling to design Watershed Investments, hence to model the impacts on selected ecosystem services. The chapter concludes highlighting the potential of the approach to contribute to adaptive management in the urban water sector, by addressing the challenges of linking diverse stakeholders and knowledge system across management levels and institutional boundaries.

    Conclusions2020In: Ecosystem Services for Urban Water Security: Concepts and Applications in Sub-Saharan Africa, Cham: Springer Nature , 2020Chapter in book (Refereed)
    Abstract [en]

    This chapter summarizes the main messages of the book, as well as dis- cusses the challenges for future research and practice to contribute to achieving water security and to implementing adaptive management in the urban water sector. Briefly, the first main message is that achieving urbanwater security through adaptive watershed planning and management, in Sub-Saharan Africa context, is a complex issue. Thus, an intuitive and flexible conceptual framework of the urban water sector from an ecosystem services perspective was proposed. It provides an overview of the main challenges and trends that characterize the sector, highlighting the specificities of the Sub-Saharan context, setting the background for further analysis. Second, if properly designed, Watershed Investments can become an important financial and governance mechanism to promote the implementation of adaptive watershed man- agement to achieve urban water security. Third, a good case study application, even if only based on desk research, can serve to inspire stakeholder and possibly prepare the ground for real-life implementation of science-informed measures to promote urban water security alongside other social goals, coordinating ongoing watershed initiatives.

    Designing Watershed Investments for Asmara and the Toker Watershed2020In: Ecosystem Services for Urban Water Security: Concepts and Applications in Sub-Saharan Africa, Cham: Springer Nature , 2020Chapter in book (Refereed)
    Abstract [en]

    This chapter presents an application of a novel operational approach for designing and assessing the impacts ofWatershed Investments, developed in Chap. 3, to the Asmara and Toker Watershed case study. Assuming urban water security and rural poverty alleviation as two objectives for Watershed Investments, the case study application explores all the steps ofthe proposed approach. The results ofthe applica- tion include spatially explicit data that allowquantitatively assessing the performance of differentWatershed Investment scenarios in terms of changes in a selected ecosys- tem service, answering to important planning and management questions. The appli- cation to the Asmara and Toker Watershed case study also highlights the challenges of addressing stakeholders’ concerns through relevant boundary work strategies.

    Analyzing Evidence of Sustainable Urban Water Management Systems: A Review through the Lenses of Sociotechnical Transitions2020In: Sustainability, E-ISSN 2071-1050, Vol. 12, no 11, p. 4481-Article in journal (Refereed)
    Abstract [en]

    Sustainability concerns and multiple socio‐environmental pressures have necessitated a shift towards Sustainable Urban Water Management (SUWM) systems. Viewing SUWM systems as sociotechnical, this paper departs from eight factors previously identified by transition research: Pressures, Context, Purposes, Actors, Instruments, Processes, Outputs, and Outcomes as a methodological framework for a structured review of 100 articles. The study seeks to analyze empirical cases of planning and implementing SUWM systems worldwide. A wide range of public actors—driven by social and environmental factors rather than by economic pressures—have initiated SUWM projects so as to locally fulfill defined social and environmental purposes. We provide evidence on the emergence of new actors, such as experts, users, and private developers, as well as on the diverse and innovative technical and societal instruments used to promote and implement SUWM systems. We also explore their contexts and institutional capacity to deal with pressures and to mobilize significant financial and human resources, which is in itself vital for the transition to SUWM. Planned or implemented SUWM outputs are divided into green (wet ponds, raingardens, and green roofs) and gray (rain barrels and porous pavements) measures. The outcomes of SUWM projects— in terms of societal and technical learning, and their institutional uptakes—are often implicit or lacking, which seemingly reduces the rate of desirable change.

    Remote Sensing and Geographic Information Systems for Flood Risk Mapping and Near Real-time Flooding Extent Assessment in the Greater Accra Metropolitan Area2017Independent thesis Advanced level (degree of Master (Two Years)), 20 credits / 30 HE creditsStudent thesis
    Abstract [en]

    Disasters, whether natural or man-made have become an issue of mounting concern all over the world. Natural disasters such as floods, earthquakes, landslides, cyclones, tsunamis and volcanic eruptions are yearly phenomena that have devastating effect on infrastructure and property and in most cases, results in the loss of human life. Floods are amongst the most prevalent natural disasters. The frequency with which floods occur, their magnitude, extent and the cost of damage are escalating all around the globe. Accra, the capital city of Ghana experiences the occurrence of flooding events annually with dire consequences. Past studies demonstrated that remote sensing and geographic information system (GIS) are very useful and effective tools in flood risk assessment and management.  This thesis research seeks to demarcate flood risk areas and create a flood risk map for the Greater Accra Metropolitan Area using remote sensing and Geographic information system. Multi Criteria Analysis (MCA) is used to carry out the flood risk assessment and Sentinel-1A SAR images are used to map flood extend and to ascertain whether the resulting map from the MCA process is a close representation of the flood prone areas in the study area.  The results show that the multi-criteria analysis approach could effectively combine several criteria including elevation, slope, rainfall, drainage, land cover and soil geology to produce a flood risk map. The resulting map indicates that over 50 percent of the study area is likely to experience a high level of flood.  For SAR-based flood extent mapping, the results show that SAR data acquired immediately after the flooding event could better map flooding extent than the SAR data acquired 9 days after.  This highlights the importance of near real-time acquisition of SAR data for mapping flooding extent and damages.  All parts under the study area experience some level of flooding. The urban land cover experiences very high, and high levels of flooding and the MCA process produces a risk map that is a close depiction of flooding in the study area.  Real time flood disaster monitoring, early warning and rapid damage appraisal have greatly improved due to ameliorations in the remote sensing technology and the Geographic Information Systems.

    Ökad demokratisering av planeringsprocessen: En analys kring segregation och ungdomars inflytande i stadsplanering2020Independent thesis Basic level (degree of Bachelor), 10 credits / 15 HE creditsStudent thesis
    Abstract [en]

    Segregation has recently been a subject of matter in the political debate. The government has been working on a strategy to actively work against increased segregation, in hopes of reducing the gap and creating a safer Sweden. One particular aspect that the government is focusing on is to increase democratization in the planning process, where one approach to increase the public participation is through citizen consultation. The purpose of this study is to examine what part public participation plays in the planning process in order to increase the democratization of society, focusing on segregated areas. Further, since today's young adults are the inhabitants of the future, the report will also analyze this generation’s participation in urban planning processes. The study aims to answer the below two questions; What is the extent of public participation and public influence in segregated areas? What is the extent of young adults participation in the planning process today and how can the engagement be encouraged throughout the planning process? In order to answer the questions posed we have decided to carry out a literature study based on previous research about public participation and segregation, as well as a case study about the city planning project Järvalyftet. We have also chosen to hold interviews to collect empirical data, these with Moa Tunström, Nazem Tahvilzadeh and Sofia Wiberg. A significant conclusion which is drawn is the fact that the term segregation per definition is not a problem, but rather that the problem lies in the negative consequences that follow. The study implies that there is an existing public participation in segregated areas, but not in the same extent as in areas with a higher socioeconomic class. Another conclusion based on Järvalyftet, is that public participation doesn't necessarily lead to public influence. Misunderstanding can occur in the transition between public participation and public influence, since citizens and involved stakeholders have different ideas about public influence. An increased interest among young adults towards urban planning needs to be created to increase their influence. By opening more forums where they are encouraged to express their opinions on planning issues, both interest and commitment will increase.

    Estimating a Polycentric Urban Structure. Case Study: Urban Changes in the Stockholm Region 1991-20042009In: Journal of urban planning and development, ISSN 0733-9488, E-ISSN 1943-5444, Vol. 135, no 1, p. 19-30Article in journal (Refereed)
    Abstract [en]

    The aims of this paper are to empirically test and evaluate methods for describing intraurban polycentricity, and to evaluate the polycentric development with respect to the regional development plan of the Office of Urban and Regional Transportation in 2001. The study area is Stockholm County and the time period investigated is 1991-2004. Three dimensions of polycentricity are analyzed: urban nuclei size relations, spatial distribution of urban nuclei, and potential interaction (accessibility). According to the methods' various qualifications in describing polycentric forms it is proposed here that a combination of methods is preferable for this subject. The polycentric structure exposes an increasing and considerable concentration of urban resources to the major urban nuclei. This concentration is combined with an increased spatial dispersal of the urban nuclei. In relative terms, the accessibility has decreased concerning the accessibility by public transportation modes and increased (workspace) or remained on almost the same level (residential space) by car transportation mode. Thus, the urban structural change in the Stockholm region corresponds to the political guidelines. In spite of this, by the increase in relative accessibility by car and decrease in the relative accessibility by public transportation modes the goal concerning higher share in public transports may not be possible to fulfill.

    Främling i konsumtionsstaden2014In: Det förflutna i framtidens stad / [ed] Krister Olsson, Daniel Nilsson, Lund: Nordic Academic Press, 2014Chapter in book (Other academic)
    Abstract [sv]

    Idag lever vi i ett globaliserat konsumtionssamhälle, i ett allt intensivare tempo där konkurrensen är hård om tid, utrymme och uppmärksamhet. I vår samtid är även kultur- och stadsmiljöerna på olika sätt ”produkter” och ”resurser”. Men hur påverkar samhällsutvecklingen kulturarvet och vår syn på dess värden? Kanske kan vi tydligare se utvecklingstrenderna och kulturarvets roll för hållbar stadsutveckling om vi blickar bakåt i tid och även vänder perspektivet mot framtiden? I Det förflutna i framtidens stad lägger en grupp forskare olika tidsperspektiv på relationen mellan kulturarv, konsumtion och hållbar stadsutveckling. Författarna arbetar till vardags med framtidsstudier, samhällsplanering, arkeologi, arkitektur och konst och de samsas här under tematiska avsnitt som framtidsvisioner, valmöjligheter, tid och rörelse i stadslandskapet. Texterna gör nedslag i vår närmiljö bland resor, detaljhandel, bostäder och livsstilsideal. Författarna frågar sig bland annat hur vi kan bygga in hemkänsla, identitet och trygghet i stadsmiljön. Kan vi återanvända historiska bostadsmodeller? Och vem bestämmer vilka minnen som är värda att bevaras – vilka föreställningar om framtiden har bäring på samtidens kulturmiljövård? Boken vänder sig till beslutsfattare, tjänstemän, studenter och en bred allmänhet – alla som har ett intresse för såväl utmaningar som lösningar för en hållbar stad.

    Abstract [en]

    Interurban-level focus during the last decade has shifted from the compact city towards a polycentric urban framework. The ability to define consistent urban structures and also link them with sustainability goals has been hindered by inconsistent evaluation methods for density and mixed functionality in a polycentric framework. The aim of this research is to test and combine various methods from these perspectives in order to define more reliable and consistent descriptions of urban structures. The methods used are spatial-density modelling using kernel convolution, a polycentric density estimation, and methods depicting mixed functionality and the association between density and mixed functionality. The empirical findings relate to planning goals at both national and international level. The study region is the municipality of Strangnas, within the Stockholm City Region since 1997. Results from the analysis reveal urban development towards further segregated land use and sprawl, as well as a decreasing link with a polycentric urban scheme. The methods developed for depicting urban form could be useful tools in the planning process and may reinforce the possibility for analysing links between urban form and sustainability aspects. This improved knowledge in turn could contribute towards formulating future planning principles.

    New urban settlements in a perspective of public and private interests. Case study: a Swedish municipality within the hinterland of the Stockholm city2008In: Journal of Geographical Systems, ISSN 1435-5930, E-ISSN 1435-5949, Vol. 10, no 4, p. 345-367Article in journal (Refereed)
    Abstract [en]

    The changes of land use patterns and urban structures could be seen as the dynamic result of the trade off between public and private interests. Thereby the land use change is to some extent unpredictable. The focus in the current study is to measure the importance of spatial location factors regarding new residential and commercial buildings in relation to existing urban amenities and political guidelines. The relative importance of the location factors was studied by multinomial regression analysis. Results from this study reveal that the location profiles of new urban object types attained here indicate strong correspondence with local political land use guidelines and to clustering. The spatial distribution of new urban settlements does not in general correspond to the monocentric urban scheme where firms and residents locate in spatial proximity to urban centres.

    Spatial Lifestyle Clusters and Access to the City: Evidence from the Stockholm Region2022In: Sustainability, E-ISSN 2071-1050, Vol. 14, no 21, p. 14261-, article id 14261Article in journal (Refereed)
    Abstract [en]

    This paper analyses the distribution of social infrastructure (accessibility to services and job opportunities) in a perspective of spatial lifestyle stratification in the Stockholm region. The study is based on a questionnaire completed by 1160 respondents, capturing individual data on attitudes, lifestyles and demography, and urban morphological qualities developed from high resolution register data. The spatial social stratification is based on a spatial cluster analysis on six lifestyles: highly success-oriented; success-oriented with high work ethics; conscious young and elder; people with weak motivations; designers; and middle-class bourgeois. They are spatially distributed in eight overlapping spatial clusters, namely: highly success-oriented and socially mixed central inner city; designers' inner suburbia; socially mixed inner suburbia; middle-class bourgeois suburbia; highly success-oriented suburbia; conscious young-elder suburbia; socially mixed exurbia; and socially mixed rurality. It turns out that people characterized by weak motivation lifestyle (low income, low education level, not success oriented, etc.) are the most negatively affected lifestyle cluster concerning accessibility to jobs and service. A total of 45% of the 'weak motivation lifestyle' respondents reside in 'socially mixed exurbia' and 'socially mixed rurality'. They experience less than 20% of social infrastructure compared to, in this respect, the most privileged spatial lifestyle cluster, the 'highly success-oriented and socially mixed central inner city' cluster. Still, surprisingly, this 'weak motivation' lifestyle is also concentrated in the 'socially mixed inner suburbia' cluster. One reason for this dual spatial concentration might be the Swedish rental policy, linked to residential use-values and a queuing system, instead of exchange values. This policy allows for a complex spatial social stratification influenced by a range of factors (lifestyle and attitudes among others), and not merely income.
