[EN] The first part of this work reviews the potential applications of satellite remote sensing to regional science research in urban settings. The availability of satellite remote sensing data has increased significantly in the last two decades. The increasing spatial resolution of commercial satellite imagery has influenced the emergence of new research and applications of regional science in urban settlements because it is now possible to identify individual objects of the urban fabric. The most common applications found in the literature are the detection of urban deprivation hot spots, quality of life index assessment, urban growth analysis, house value estimation, urban population estimation, urban social vulnerability assessment, and the variability of intra-urban crime rates. The satellite remote sensing imagery used in these applications has medium, high or very high spatial resolution (Landsat MSS, Landsat TM and ETM+, SPOT, ASTER, IRS, Ikonos and QuickBird). Consistent relationships between socio-economic variables derived from censuses and field surveys and proxy variables of vegetation coverage measured from satellite remote sensing data have been found in several cities in the US. Different approaches and techniques have been applied successfully around the world, but local research is always needed to account for the unique elements of each place. Spectral mixture analysis, object-oriented classifications and image texture measures are some of the techniques of image processing that have been implemented with good results. This work contributes empirical evidence about the usefulness of remote sensing imagery to quantify the degree of poverty at the intra-urban scale. This concept is based on two premises: first, that the physical appearance of an urban settlement is a reflection of the society; and second, that the people who reside in urban areas with similar physical housing conditions have similar social and demo- graphic characteristics. We evaluate the potential of the image-derived urban fabric descriptors to explain a measure of poverty known as the Slum Index. We found that these variables explain up to 59% of the variability in the Slum Index. Similar approaches could be used to lower the cost of socioeconomic surveys by developing an econometric model from a sample and applying that model to the rest of the city and to perform intercensal or intersurvey estimates of intra-urban Slum Index maps. The last part of this work analyzes the relation between the urban layout and crime. The link between place and crime is at the base of social ecology theories of crime that focus in the relationship of the characteristics of geographical areas and crime rates. The broken windows theory states that visible cues of physical and social disorder in a neighborhood can lead to an increase in more serious crime. Based on the premise that a settlement's appearance is a reflection of the society, we ask whether a neighbor- hood's design has a quantifiable imprint when seen from space using urban fabric descriptors computed from VHR imagery. The percentage of impervious surfaces other than clay roofs, the fraction of clay roofs to impervious surfaces, two structure descriptors related to the homogeneity of the urban layout, and the uniformity texture descriptor were all statistically significant. Areas with higher homicide rates tended to have higher local variation and less general homogeneity; that is, the urban layouts were more crowded and cluttered, with small dwellings with different roofing materials located in close proximity to one another, and these regions often lacked other homogeneous surfaces such as open green spaces, wide roads, or large facilities. These results seem to be in agreement with the broken windows theory and CPTED in the sense that more heterogeneous and disordered urban layouts are associated with higher homicide rates. / [ES] La primera parte aporta una revisión de las aplicaciones de la teledetección satelital en la investigación de ciencia regional en entornos urbanos. La disponibilidad de imágenes satelitales se ha incrementado significativamente en las dos últimas décadas, al tiempo que la resolución espacial ha venido aumentando, lo que ha influenciado el surgimiento de investigaciones y aplicaciones de ciencia regional en zonas urbanas. Las aplicaciones más comunes son la detección de hot spots de pobreza urbana, la evaluación de índices de calidad de vida, el análisis del crecimiento urbano, la estimación de valores de vivienda, la estimación de población urbana, la evaluación de la vulnerabilidad social y las variaciones intra-urbanas en tasas de crimen. Las imágenes satelitales usadas tienen resolución espacial media, alta o muy alta (Landsat MSS, Landsat TM y ETM+, SPOT, ASTER, IRS, Ikonos y Quickbird). Se han encontrado relaciones consistentes entre variables socio-económicas obtenidas de censos y encuestas y variables de la cobertura de vegetación en varias ciudades de Estados Unidos. Algunas de las técnicas que se han implementado y obtenido buenos resultados son el análisis de mezcla espectral, las clasificaciones orientadas a objetos y las medidas de textura de la imagen. Se aporta evidencia empírica acerca de la utilidad de las imágenes satelitales para cuantificar el grado de pobreza a escala intra-urbana. Se basa en dos premisas: primero, que la apariencia física de un asentamiento urbano es un reflejo de la sociedad que lo habita; y segundo, que la población de áreas urbanas con condiciones físicas de vivienda parecidas tiene características sociales y demográficas similares. Evaluamos el potencial de los descriptores del tejido urbano extraídos de la imagen para explicar una medida de pobreza conocida como el índice Slum. Encontramos que esas variables explican hasta un 59% de la variabilidad en el índice Slum. Aproximaciones similares a esta podrían usarse para disminuir el costo de encuestas socioeconómicas por medio del desarrollo de un modelo econométrico usando una muestra y luego aplicando el modelo al resto de la ciudad, y para elaborar estimaciones inter-censales o inter-encuestas de mapas intra-urbanos del índice Slum. La última parte analiza la relación entre el trazado urbano y crimen. El enlace entre el lugar y el crimen está en la base de las teorías socio-ecológicas de crimen que se enfocan en la relación de las características de las áreas geográficas y las tasas de crimen. La teoría de las ventanas rotas afirma que las evidencias visibles de desorden físico y social en un barrio pueden llevar al incremento de crímenes más serios. Con base en la premisa de que la apariencia de un asentamiento es un reflejo de la sociedad, nos preguntamos si el diseño del barrio tiene un impacto cuantificable cuando se observa desde el espacio usando descriptores del tejido urbano obtenidos de imágenes de muy alta resolución. El porcentaje de superficies impermeables diferentes a los techos de arcilla, la fracción de techos de arcilla sobre las superficies impermeables, dos variables de estructura relacionadas con la homogeneidad del trazado urbano y la variable de textura uniformidad resultaron estadísticamente significativas. Las áreas con tasas de homicidio más altas tienden a tener mayor variación local y menor homogeneidad general; esto es, los trazados urbanos son más desordenados y hacinados, con pequeñas viviendas que tienen materiales diferentes en sus techos localizadas muy cerca unas de otras, y estas áreas carecen a menudo de otras superficies homogéneas tales como espacios verdes abiertos, vías amplias y grandes construcciones industriales o institucionales. Estos resultados parecen estar en acuerdo con la teoría de las ventanas rotas y CPTED en el sentido de que los trazados urbanos más desordenados y heterogéneos están asociados con tasas de homicid / [CA] La primera part aporta una revisió de les potencials aplicacions de la teledetecció espacial a la investigació en ciència regional en entorns urbans. La disponibilitat de dades de percepció remota des de satèl·lits s'ha incrementat significativament a les dues últimes dècades. La resolució espacial de les imatges de satèl·lit comercials també han anat augmentant i això, ha influït en l'aparició de investigacions i aplicacions a la ciència regional en assentaments urbans. Les aplicacions més comunes trobades a la literatura són la detecció de punts calents de pobresa urbana, l'avaluació dels índex de qualitat de vida, les anàlisis de creixement urbà, l'avaluació de la vulnerabilitat social i les variacions intraurbanes de les taxes de crims. Les imatges de satèl·lit emprades tenen resolució espacial mitjana, alta o molt alta (Landsat MSS, Landsat TM i ETM+, SPOT, ASTER, IRS, Ikonos y Quickbird). S'han torbat relacions consistents entre variables socioeconòmiques obtingudes de censos i enquestes i variables de la cobertura de vegetació en varies ciutats del Estats Units. Algunes de les tècniques que s'han implementat i han donat bons resultats són l'anàlisi de mescla espectral, les classificacions orientades a objecte i les mesures de textura de les imatges. Es aporta evidència empírica sobre la utilitat de les imatges de satèl·lit per quantificar el grau de pobresa a escala intraurbana. Es bassa en dues premisses: primer, que l'aparença física d'un assentament urbà n'és un reflex de la societat que l'habita; i segon, que les persones que resideixen en àrees urbanes amb condicions físiques de vivenda paregudes tenen també característiques socials i demogràfiques similars. Avaluem el potencial dels descriptors del teixit urbà extrets de la imatge per explicar una mesura de pobresa coneguda com index Slum. Trobem que aquestes variables expliquen fins un 59% de la variabilitat de l'índex Slum. Aproximacions semblants a aquesta es podrien emprar per a disminuir el cost de les enquestes socioeconòmiques mitjançant el desenvolupament d'un model economètric utilitzant una mostra i després aplicant el model a la resta de la ciutat, i per elaborar estimacions inter-censals o inter-enquestes de mapes intraurbans de l'índex Slum. La darrera part analitza la relació entre el traçat urbà i el crim. L'enllaç entre el lloc i el crim està a la base de les teories socio-ecològiques del crim que es centren en la relació de les característiques de les àrees geogràfiques i les taxes de crims. La teoria de les finestres trencades afirma que les evidències visibles de desordre físic i social d'un barri pot portar a l'augment de crims més greus. Basant-se en la premissa de que l'aparença d'un assentament n'és el reflex de la societat, ens hi preguntem si el disseny del barri té un impacte quantificable quan s'observa des de el espai, utilitzant descriptors del teixit urbà obtinguts de imatges de molt alta resolució. Han resultat estadísticament significatius el percentatge de superfícies impermeables diferents a les teulades de argila, la fracció de teulades d'argila sobre les superfícies impermeables, dues variables d'estructura relacionades amb la homogeneïtat del traçat urbà i la variable de textura de uniformitat. Les àrees amb taxes d'homicidi més altes tendeixen a presentar una major variació local i una menor homogeneïtat general; és a dir, el traçats urbans són més desordenats i amuntonats, amb petites vivendes que tenen materials diferents a les seues teulades localitzades molt prop unes d'altres, i aquestes àrees manquen sovint d'altres superfícies homogènies, com ara espais verds oberts, vies amplies i grans construccions industrials o institucionals. Aquests resultats pareixen estar-hi d'acord amb la teoria de les finestres trencades i CPTED en el sentit de que els traçats urbans més desordenats i heterogenis estan associats amb taxes d'homicides m / Patiño Quinchía, JE.

The creation of sustainable and safe environments nowadays moves more and more into focus for urban planners and architects. Cities should be designed in a way to contribute to social cohesion, shaping an inclusive environment and focusing on the wellbeing of its citizens. Nevertheless, these processes can be undermined by public crime and the fear of crime, which is not only affecting aspects of personal safety but also affecting the people’s behaviour. Reasons why criminality occurs are manifold, impacted by a dynamic set of socioeconomic, demographic, personal but also environmental aspects. In recent years especially the impact of factors related to urban and environmental design respectively planning received rising attention in the field of crime prevention. However, the implementation of strategies regarding ‘crime prevention through environmental design’ or ‘designing out crime’ is still in its early stage in Sweden.   This study aims to investigate spatial and temporal patterns of public crime for the case of Umeå in order to identify potential risk areas, which could receive particular attention regarding crime prevention through environmental design (CPTED). In this sense a GIS based spatial analysis had the aim to detect statistically significant hotspots of crime and furthermore to assess the development of these hotspots over time. In order to understand the nature of public crime and criminal behaviour in Umeå in a more holistic way, also temporal aspects regarding the occurrence of crime were analysed. One particularly vulnerable neighbourhood was examined with a qualitative field observation regarding the principles of crime prevention through environmental design in order to assess in which way the built environment is designed and suited to prevent and deter criminality.   Umeå displays rather clear patterns of higher crime activity, assigned to seasonal, weakly and daily periods, which are connected to higher activity in the public space. Also from a spatial perspective certain patterns are detectable with a higher vulnerability for crime at spots which generate higher activity such as shopping areas or neighbourhoods with nightlife and transport hub functions, and in general neighbourhoods with a higher building density. The neighbourhood of Ålidhem displayed thereby a high concentration of criminality, marked as a constant or even intensifying hotspot for the entire period of investigation. The results of the field observation regarding principles of CPTED are especially indicating a lack of maintenance and furthermore the street and building layout is contributing to disorientation. On the other hand, the area is in most cases well equipped for natural surveillance and provides a high amount of locations for leisure and recreation in order strengthen social cohesion.

Det pågår många brottsförebyggande arbeten idag i Sverige och dessa sker oftast genom sociala insatser, men det är allt för få satsningar som avser den fysiska miljön. Den påverkar oss människor mer än vad vi tror. Syftet med denna studie är att göra en systematisk analys av den fysiska miljön i tre särskilt utsatta områden och undersöka hur dessa miljöer kan skapa brottsmöjligheter. Områdena Bergsjön, Rinkeby och Vivalla undersöks i denna rapport, dessa är valda till särskilt utsatta områden och där finns en rådande problematik och även en högre koncentration av kriminella (Polisen, 2017). Fakta och teorier som bland annat rutinaktivitetsteorin, CPTED och Jane Jacobs stadsplaneringsidéer behandlas i studiens bakgrund. Likheterna mellan områdenas fysiska miljöer sammanställs genom kartjämförelser, platsanalyser och intervjuer.    Metoden visade att trafiksepareringen hade skapat många mörka gångtunnlar in till områdena som skapade oattraktiva och otrygga inträden. Att områdena var bilfria ledde ytterligare till att många ställen blev ödsliga, obevakade och otrygga. Områdenas byggnader var vidare inte varierade och det kunde förekomma flera likadana hus bredvid varandra, till och med över hela områden. För en brottsling är det enklare att begå brott i en enkel detaljfattig miljö, eftersom det då är färre saker att hålla koll på och det blir mycket enklare att begå brottet när övriga människor inte ser sig omkring sig. En annan likhet var gatustrukturen, till exempel hade de tre områdena återvändsgator som inte sammanvävde vägarna med varandra. Detta bidrog till segregerade områden och svårigheter för polisen att komma fram och utföra sina insatser på ett effektivt sätt. Även byggnadernas placering mot gatan påverkade huruvida det skapades naturlig övervakning som kunde motverka brottslighet. Därmed blev slutsatsen att likheterna i den fysiska miljön mellan de tre områdena kan underlätta möjligheterna för att begå brott. / There is many jobs today in Sweden for crime prevention and these happen often through social efforts, but there is way too few of these for the physical environment that actually affects us more than we think they do. The purpose with this study is to make a systematical analysis of the physical environment in three deprives areas and examine if these environments can create crime opportunities. The chosen places are Bergsjön, Rinkeby and Vivalla with current problematic and high crime concentration (Polisen, 2017). Fact and theories such as the Routine Activity Theory, CPTED and Jane Jacobs’s urban ideas is treated in the study’s background. Similarities between the areas physical environment is compiled through map comparisons, place analysis and interviews.   The methods result showed that the traffic separation created many dark tunnels into the areas, which caused unattractive and insecure entries. The buildings in the areas were also not varied and there could be a several of similar houses next to each other or over the whole field. It can be easier for a criminal to commit crimes in a simple surrounding without details, because it is fewer things to keep track of and it becomes much easier to commit the crime when people doesn’t look around themselves. Another similarity was the street structures, for example the three areas had blind alleys that didn't interweave the streets with each other. This contributed to segregated areas and difficulties for the police to arrive and perform their efforts effectively. Even the buildings placement to the street affected whether they had a natural surveillance that could prevent crime. This concluded that the physical environment in these three deprived areas can affect the emergence of crime.

In this section of research, a new crime prevention model for residential neighbourhoods, namely the HONC - against crime model was developed. This model is based on the Crime Prevention Through Environmental Design principles (CPTED). The first three elements of this model are intended to better the function of CPTED in neighbourhoods. The elements are as follows: H = Healthy lifestyle O = Online (Information technology) N = Nature C = CPTED The effectiveness of the elements in the prevention of crime was tested in two gated communities and one open neighbourhood, namely Woodlands Lifestyle Estate, Prairie Estate and Glossa Estate. All these neighbourhoods are situated in Garsfontein, a suburb of Pretoria, South Africa. Woodlands Lifestyle Estate was designed in accordance with these principles. This neighbourhood is situated next to a nature reserve called Moreletaspruit. The fence facing this reserve is a steel palisade to provide a view of the scenery. The other three fences are solid brick. This Estate has two entrances with formal access control. Woodlands has a specifically designed lifestyle centre which contains a gym, squash courts, swimming pool, tennis courts and an entertainment area. Pedestrian routs run from this centralised centre throughout the neighbourhood with water features and adequate lighting. Prairie Estate is also a gated community, fenced off with a brick wall and reachable through one entrance with formal access control. The architectural design of dwellings within this neighbourhood was left to the discretion of different developers. The only area for recreational activity within this neighbourhood is the fenced off club house and swimming pool. Glossa Estate is situated diagonally across Woodlands Lifestyle Estate, and is an open neighbourhood. It has three entrances with one guard patrolling the interior neighbourhood. This neighbourhood was designed with a park as a recreational area. The park was not in use and became overgrown, which created a crime problem, and it was therefore fenced off and the gate locked. Only the element of a healthy lifestyle could be proven as influential in the incidence of crime. The last three elements only served as guidelines and need to be tested in further research. / Criminology / D.Litt. et Phil. (Criminology)

Denna uppsats har syftat till att identifiera lärdomar från två tidigare utsatta områden (Rannebergen i Göteborg och Klockaretorpet i Norrköping) och ett tidigare särskilt utsatt område (Gårdsten i Göteborg). Intervjuer med polis, kommun, socialförvaltning, bostadsbolag och civilsamhälle har genomförts i varje stadsdel för att undersöka vilka insatser och åtgärder som har genomförts av aktörerna i områdena. Tidigare forskning och teorier har behandlat sociala risker, kollektiv förmåga, socialt kapital, fasteorin, CPTED och Jane Jacobs stadsplaneringsideal. Resultatet från Klockaretorpet visar på betydelsen av samverkan och relationsskapande insatser med fokus på delaktighet, kontinuitet och snabba ageranden. I Gårdsten har utvecklingen vänt mycket med hjälp av det starka lokala bostadsbolaget Gårdstensbostäder som bland annat använt hårdare strategier gentemot sina hyresgäster för att skapa kontroll och öka tryggheten i området. I Rannebergen råder det dock en diffus förståelse över områdets faktiska situation då aktörer anser att det snarare är en pågående negativ utveckling i området trots en borttagning från polisens lista över utsatta områden. Slutsatsen blir därmed att polisens klassificeringar inte alltid visar den faktiska verkligheten och att en borttagning inte innebär att all problematik är borta eller att insatser kommer att upphöra. Slutligen behöver alla aktörer i ett samhälle kliva fram, ta plats och ansvar i områdena för att vända en negativ utveckling. Det är viktigt att se på områdenas möjligheter och förstärka insatser även när utvecklingen går åt en positiv riktning, vilket pekar på betydelsen av kontinuitet och långsiktighet. / This thesis has aimed to identify lessons learned from two previous vulnerable areas (Rannebergen in Gothenburg and Klockaretorpet in Norrköping) and a previous particularly vulnerable area (Gårdsten in Gothenburg). Interviews with the police, municipalities, social service center, housing companies and civil society have been conducted in each district to examine which initiatives/efforts and measures have been implemented by the actors in the areas. Previous research and theories have included social risks, collective efficacy, social capital, phase theory, CPTED and Jane Jacob's urban planning ideals. The results from Klockaretorpet showed the importance of collaboration and relationship-building initiatives with a focus on involvement, continuity and quick actions. In Gårdsten, the development has reversed a lot with the help of the strong local housing company Gårdstensbostäder, which, among other things, has used tougher strategies towards its tenants to create control and increase safety in the area. In Rannebergen, however, there is a diffuse understanding of the area's actual situation as actors believe that there is rather an ongoing negative development in the area despite a removal from the police's list of vulnerable areas. Hence, the conclusion is that the police's classifications do not always show the actual reality and that a removal does not mean that all problems are gone or that efforts should cease. Finally, all actors in a society need to step forward, take place and responsibility in the areas to reverse a negative development. It is important to look at the areas' opportunities and strengthen efforts even when development is moving in a positive direction, which points to the importance of continuity and long-term perspective.

The problem investigated in this research is the ongoing crime threat and the extreme risks which impact negatively on the sustainability of the Rosslyn Industry - the industrial hub of Tshwane in the Gauteng Provence of South Africa. Businesses in Rosslyn are desperate for a solution that will mitigate these crime threats and risks, and ensure the future sustainability of this important industrial community. An intervention model is urgently required to prevent this type of crime, not only as a short term solution but as a sustainable long term intervention. This research study initiated the collaboration required for the successful implementation of a Crime Prevention Intervention Model (CPIM) in the Rosslyn industrial environment. The intended crime prevention model has been designed in such a way that it addresses the entire environment of crime that prevails in the Rosslyn area involving both the offender and the victim. This design is rooted in the ontology of Environmental Criminology and more specific on the applied epistemology of Crime Prevention Through Environmental Design (CPTED). Participants in this project are representatives who are responsible for all security functions in both big businesses and small enterprises. And with their dedicated assistance the research findings disclosed the current crime status of the Rosslyn environment regarding the threat, risk, security vulnerabilities, controls and needs: • Crime and its causal factors, in Rosslyn, are rife and no noteworthy action has been implemented to mitigate these threats. • Collaboration between Rosslyn role players (neighbours, local government and law enforcement) is for all purposes non-existent. • And to complicate matters even more, knowledge of how to effectively mitigate crime is limited and handicapped by the re-active physical security methods currently being used. • The implication of these findings is that the status quo will eventually render business in Rosslyn unsustainable. Thus a CPIM in Rosslyn is inevitable. What was crucial to this research and to the CTPED design is the detailed sourcing of accurate data addressing the experiences and the needs the respondents identified in the current Rosslyn crime situation concerning; status, the threat, risk, security, vulnerabilities and controls. In order to achieve this level of data sourcing and assimilation, the essential features of the research method were based on a mixed approach where quantitative and qualitative methods were implemented in parallel. The diverse fields, sources and respondent mix required for a Rosslyn Industry CPIM also necessitated a MIT (Multi,-Inter,-Trans,-Disciplinary) approach. This MIT requirement is successfully facilitated through the applied criminological CPTED approach. The CPIM is based on the combined outcomes of the following three research fields: • Field-one: Environmental criminology theories are researched through an in-depth literature review to demonstrate the criminological grounding of crime prevention and to guide its application through the development of an applied CPTED SUITE. • Field-two: Supply Chain Security (SCS) are researched through an in-depth literature review to establish its criminological relevance and applications. SCS requirements are identified and built into the Field-Three research process and tested for relevance and for incorporation in the CPTED SUITE. • Field-three: Based on a mixed research process, using a custom designed Criminological Risk Analyses tool incorporating scheduled interviews and questionnaires, the crime and needs profile of the Rosslyn Industry are uncovered and analysed. The results are filtered through the CPTED SUITE to indicate the correct criminological approach for mitigating the identified problems and needs. Even though this study takes an applied crime preventative approach, the criminological-philosophical mould of crime prevention is imperative for the effective application of the CPTED. Security and crime prevention training, planning and application, without this approach will remain underdeveloped and outdated. Finally the underlying intention of this research is for this Crime Prevention Intervention Model (CPIM) to be adapted and implemented and to serve as a guide or a benchmark for security practitioners in any industrial environment that has the same crime threats and crime risk challenges. / Criminology and Security Science / D.

Text in English with abstracts in English, isiZulu and Xhosa / This research applies the Near Repeat Calculator (NRC) to identify near repeat residential burglary patterns in the Hillcrest (KZN) policing area for the first time. A total of 490 residential burglaries, over a 12-month period, reported to Hillcrest police station were mapped (geocoded) and the near repeat calculations were visualised using the Geographic Information Systems (GIS). The month-to-month near repeat calculations are analysed and suggest that the NRC is a valuable tool that can predict the space-time locations of near repeat residential burglaries in the Hillcrest policing area. / Lolu cwaningo lusebenzisa i-Near Repeat Calculator (NRC) ukuhlonza amaphethini okuphindaphindeka kwezigameko zokugqekezwa kwamakhaya endaweni eyenganyelwe yisiteshi samaphoyisa sase-Hillcrest (KZN).
