Background: Agriculture is among the relevant factors for the formation of cities and it has been an integral part of city life throughout history. Despite the increase in population growth, urban agriculture can offer a unique opportunity for improving the livelihood of individuals through the practice of growing food in urban green spaces. Nevertheless, maintaining urban green spaces as part of the urban fabric presents a unique challenge in an environment where there is a shortage of housing and urban space is limited for development. Allotment gardens might be seen as compensation for the lack of green space and private gardens in cities, especially in dense urban areas. However, due to the long waiting list for renting out, not everyone can get access to growing locally cultivated food and other benefits, especially people who are less privileged and cannot afford private gardens. Objective: The aim of this thesis, therefore, was to design a proposal for urban green space, Ekebydalen, to show how to integrate allotment gardening with other social activities. Also, as an input to the proposal, the history of allotment gardens and the theory of sustainable wellbeing was reviewed, and local public participation was investigated. Method: Literature was extensively reviewed in an attempt to identify relevant studies and better understand the context and characteristics of allotment gardens from a social and environmental context, the change in its land use, and accessibility; all in the perspective of the general development of urban agriculture and specifically in allotment movement through history in Sweden. Moreover, Site observation was conducted in a purposely selected allotment garden, Ekebydalen, Uppsala city. Also, an online and paper-based self-administered cross-sectional survey was done among 40 participants. Result: 6 different allotment gardens were observed and characterized. Based on the case study (observation), the Ekebydalen allotment garden was chosen as the main site for further pro-posal development. (60%) of the respondents in the survey were middle-aged (30 -50 years old) women (77.5%), most of them with university education (88%) and Swedish background (90%). Despite the participants has reported living in close proximity to the gardens, around a fourth of them reported having waited for more than six months. Gardening and nature interest (100%), socializing (15%), food complement (62%), and maintaining wellbeing (65%) are the motivation for renting allotment gardens. Conclusion: This thesis argues that the economic and wellbeing values of allotment gardens are perceived as highly significant compared to the social benefit that is allegedly seen less. Nevertheless, the social value can be seen as equally important if integrated as an activity with other social activities in a city, especially in urban communities that don't have enough space for gardening and are caught in their busy lives. Moreover, a design strategy was proposed to show how the allotment garden can be integrated as an activity for cultivation and recreation use (Cultivation park). This thesis has also implied that policy support, institutional recognition, and strong political will from policymakers and planners are required to bring urban agriculture into city planning for improving the quality of life for the people living and working in cities.

The objective of this report was to study how some countries work in practice with the ecosystem service concept. The approach chosen was rather broad focusing on green infrastructure planning, development or management including urban, rural and coastal areas at all scales. The countries chosen were Great Britain, Germany and Norway, since this allowed to read documents in the national languages. For each country also the national ecosystem service assessments based in the EU biodiversity strategy to 2020 have been investigated. It can be concluded that the three countries have come differently far in their work to implement the ecosystem service concept in planning practice. Great Britain can be seen as most advanced with comprehensive assessments at national level and regional and local examples which take their point of departure in the ecosystem service concept. The green structure plans of Birmingham and Manchester as well as the work in the South Downs can be pointed out as inspiring examples. In Germany comprehensive assessments at national levels have been carried out in later years. The practical examples found have often a research connection or had not their starting point in the ecosystem services concept, but have been interpreted within its context afterwards. This might be seen as an indication that the implementation of the ecosystem service concept in Germany at regional and local level outside research environments is still limited. Norway has comparable work ongoing regarding the implementation of the ecosystem service concept despite not being member of the EU and thus not been obliged to follow the EU biodiversity strategy. National assessments of ecosystem services have been carried out, partly in cooperation with the other Nordic countries. The number of research environments working with the ecosystem service concept is of course smaller than in the other countries considered here. However, in Norway as in Sweden, there is an ambition to implement the ecosystem service concept within municipal planning. Interestingly, in Norway the ecosystem service concept has also been integrated in the environmental impact assessment legislation. Studying these three countries' approach to work with the ecosystem service concept in practice in relation to green infrastructure has given interesting first insights. To get a more comprehensive and detailed overview further studies would be needed, preferably including site visits and personal contact with research institutes leading in the field as well as meeting local and regional authorities.

The involvement of local communities in public space planning and design processes is widely promoted as an essential element of landscape architecture and urban design practice. Despite this, there has been little theorisation of this topic within these fields. Furthermore, the implementation of ideals and principles commonly found in theory are far from becoming mainstream practice, indicating a significant gap between the theory and practice of participation. This thesis aims to contribute to the development of theories of participation in the planning and design of public spaces. It steps away from the prevailing normative and procedural approach to theory development, and instead adopts a critical approach grounded on the deep understanding of the challenges of participation in the planning and design of public spaces. Case studies of two urban renewal projects, in Medellin, Colombia, and in Barcelona, Spain, and their participatory processes, are used for building up the theoretical contribution. The empirical and theoretical findings foreground the contextual and political nature of participatory processes. Contextual, in the sense that the implementation of ideals and principles found in theory is facilitated or hindered by the social, political and economic context in which a participatory process takes place. Political, in the sense that in complex contexts that comprise a wide range of actors, and where contrasting goals and agendas are at stake, the implementation of these theoretical ideals and principles is significantly challenged by politics involving deep differences, conflicts and power relations. The findings also show that prevailing theories of participation within landscape architecture and urban design do not take into consideration the contextual and political nature of participatory processes. This renders these theories weak in their capacity to respond to the challenges encountered by participatory processes in contemporary public space projects. This is particularly so as the dynamics of increasing pluralisation, muliticultarisation and neoliberalisation of cities create contexts that hinder the implementation of the ideals and principles found in theory, and increase the challenges caused by their political nature. Consequently, this thesis proposes a new theoretical approach to participation in the planning and design of public spaces, that allows context-based distinctions and judgements about the qualities of participatory practices for just decision-making. Difference, conflict and power are central in this approach. This thesis establishes this theoretical departure point and makes a significant contribution towards the development of the proposed theoretical approach.

This thesis focuses on the territorial dimension of democracy by studying the division of Swedish municipalities. It consists of two parts focusing on two types of changes to the division of municipalities: amalgamation and secession. The consequences of a series of amalgamation reforms are the starting point for the first part. The question is if the new structure of the municipalities following from amalgamation, e.g. increased size, changed centre-periphery relations and an increased number of urban areas within municipalities, has had any importance for local democracy. The structural factors are looked at in the light of three aspects of democracy: municipalities as community units, their democratic legitimacy and political participation. This study shows that amalgamations can have negative effects for democracy and the conclusion is that the optimal division, from a democratic point of view, is one of small municipalities with only one dominating urban area in each municipality. As for secession, the study shows that few citizens want their part of the municipality to secede, except for those who live in parts that have had an application for secession rejected in recent years. The most important reason for supporting secession is that it would improve democracy. The main reason for opposing secession is that it would lead to decreased efficiency. The study also shows that certain conditions may change the attitude to secession, but these conditions cannot explain why a higher proportion than average is positive to secession in municipality parts that have applied for secession in recent years.

Bergslagen in south-central Sweden is an informal region with a long history of intensive land use. The legacies of than 2000 years of integrated use of ore, forests and water major national and international economic importance now involve several challenges for the maintenance of landscapes. This includes sustainability of rural and urban communities, of green infrastructures for natural capital and human well-being as well as of forests, river basins and mining. In response to this cross-sectoral integration necessary at multiple levels of public, private and civil as well as academia and schools. Landscapes need thus to be viewed as integrated socio-ecological systems. Collaboration and continuous learning among actors and stakeholders are needed for sustainable use and management of landscapes' goods, services and values. To support this requires (1) data, monitoring and assessment of different aspects of sustainability, (2) continuous knowledge production about material and immaterial landscape values relevant for the management of ecological, economic, social and cultural dimensions, (3) information and communication using both traditional media, as well as (4) through art and culture. the vision to contribute to satisfying these requirements Sustainable Bergslagen initiative emerged gradually since 2004 as a multi-level partnership for sustainable landscapes (www.bergslagen.org). By joining the International Model Forest Network (IMFN), and the network for Long Term Socio-Economic and Ecological Research (LTSER), actors and stakeholders can learn from other regions' sustainable development processes, and make Bergslagen more visible internationally.

Lawns have a significant influence on the cityscape as one of the essential elements of green spaces and an important part of people's everyday lives. Most people in the Western world view lawns as a compulsory element of the urban landscape, almost an icon, without questioning their social, symbolic, ecological or aesthetic values. This research is a part of the conceptual framework and methodological approaches that are being used in an ongoing transdisciplinary collaboration project to study lawns in Sweden as a social and ecological phenomenon.The overall aim of this study was to investigate social and cultural perceptions of lawns, as well as motives behind decisions about the establishment and management of lawns in Sweden. Two multifamily housing typologies, the 'Million Programme' and People's Homes', were examined due to their dominance in Swedish cities. We also studied how an alternative vision of conventional lawns can be applied and accepted by urban residents. We estimated lawn cover in multi-family housing areas and links to people's perception and use of lawns. Questionnaires, semi-structured interviews and observational studies were used (N = 300). Our results showed that people like lawns even if they do not always directly use them. Lawns cover the most significant amount of outdoor spaces in all multi-family residential areas and accompany people everywhere from the house to the schoolyard or park. The total lawn cover in the study areas was 27.8%. Lawns were particularly valued as important places for different outdoor activities (playing, resting, picnicking, walking, socialising) and enjoying the green colour. However people do not want to use a vast monotonous lawn, but a variety of spaces that provide good conditions for different senses (sound, smell, touch and sight) and activities. Alternative lawns were also appreciated by many citizens, politicians, planners and managers. The implementation of new types of lawns requires special planning and design solutions adjusted for each particular neighbourhood.

Studien redovisar den tredje mätningen som följer upp förändringar av trafikanternas hastighetsval och hastighetsefterlevnad på det kommunala huvudvägnätet i tätort. Resultaten visar att de genomsnittliga reshastigheterna ligger under gällande hastighetsgräns, men att bristande hastighetsefterlevnad fortfarande är ett problem. År 2009 fattades ett riksdagsbeslut som innebar ett mål att antalet dödade i vägtrafiken skulle halveras mellan åren 2007 och 2020. En av indikatorerna för att följa utvecklingen är "hastighetsefterlevnad på det kommunala vägnätet". Ett delmål är att minst 80 procent av trafikarbetet ska ske inom gällande hastighetsgräns. År 2012 var startår för mätserien och under 2015 genomfördes den tredje uppföljande mätningen. ; In 2009 the Swedish Parliament passed a resolution stating that by 2020 the number of fatalities from road traffic crashes should be reduced to half the level in 2007. This corresponds to a maximum of 220 deaths in 2020. In order to monitor progress toward this goal, yearly national follow-up studies are conducted to examine trends in the numbers of people killed and severely injured, along with a number of indicators. One of these indicators is speed limit compliance on the municipality streets; the milestone here is to have at least 80 per cent of all traffic travelling within the speed limit. The aim of the present study is to report the changes between the years 2014 and 2015 concerning driver speed levels and speed limit compliance on the main municipality streets. The annual measurement series started in year 2012 and with the measurement series from 2015, this third follow-up was performed.

Climate changes point to the needs to find sustainable materials for residential multistorey housing as a growing proportion of populations across the world live in urban areas. Despite positive environmental effects, wood has a limited use in multistorey constructions even in countries with a strong tradition to use wood in residential housing, such as Sweden. As new materials, techniques were developed and studies of properties of wood as a construction material were communicated, and legislation was altered in Sweden in the mid-1990s, allowing for the use of wood in multistorey housing. The expected market growth was slow and uneven even when incentivizing programs were developed. This chapter explains consumer perspectives in a town, Växjö, where the tradition of using wood in multistorey construction is strong. It points to the needs of knowing more about consumers' perspectives—in order to communicate added values, that is, environmental benefits, in suitable market channels.

During the late 16th century, and even more so in the 17th century, when Sweden was a great power, the extent of Swedish town-planning activity was unparalleled in Europe. Most of the older towns in Sweden and Finland can be said to take their character from this period. The thesis covers all Swedish town-planning in the areas under Swedish rule 1521–1721, and areas of Swedish interest outside this, including today's Estonia and parts of Russia, Latvia, Poland, Germany, and USA. 175 sites are studied and in total 338 projects and just above 600 town plans. Part I consists of thematic studies, part II a synthesis, and part III studies of the individual towns. The study aims at the broader picture of Swedish town-planning of this period, based on a re-assessment of existing knowledge of individual towns, but adding new material and asking new questions. It seeks to assist the conservation and the future planning and design of the urban environment. Major questions raised concern different kinds of planning measures, the design of plans and how they were devised, functional demands and aesthetic considerations, the impact of great fires and the significant figures of the time. The town-planning illustrates the political and economical development of the kingdom and played a fundamental role in the radical change of society that took place in this era. Intensive town-planning activity starts in the mid-1500s but the major rise begins in the early 17th century and reaches its peak in the 1640s and '50s. Three main categories of town-planning measures can be distinguished: new construction, which includes relocation of older towns and new foundations (100 all told), town plan changes in existing towns, including redevelopment, extension and separate suburbs (about 170), and measures relating to fortifications (some 65 fortifications only and another 90 included in combined measures). The right-angular gridiron plans dominate completely. They can be divided into three main groups: 'simple, regular', 'pragmatic', and 'elaborate'.

Antimicrobial resistance (AMR) is one of the biggest threats against public health in the world. Antimicrobial substances are used within all different sectors and contribute to development of AMR. Global action against irresponsible use of antibiotics and further development of AMR has been of great concern in the last years and risk factors are being pointed out. Low- and middle-income countries (LMICs) have a precarious role in the matter. Insufficient health care systems, poor law enforcement and, high accessibility of over-the-counter drugs (OTCs) are contributing to the unregulated use of antibiotics. Poorly developed surveillance programmes make it hard to correctly analyse the situation of both antimicrobial use (AMU) and AMR. Bangladesh, like its neighbouring countries, faces a lot of challenges regarding public health. One of the major concerns related to public health is access to safe food. Food products can be contaminated with toxins, chemical substances, and microbial organisms, including AMR-bacteria. Furthermore, national programmes for surveillance of AMU and AMR are inadequate. In this study, data from previously done field studies by Bangladesh Livestock Research Institute (BLRI), Bangladesh Food Safety Authority (BFSA), International Livestock Research Institute (ILRI), and International Food Policy Research Institute (IFPRI) and newly collected information from interviews were put together to analyse the AMR situation in Bangladesh. Sampling of food products (tomato, chicken, fish) from traditional markets and supermarkets was done at three locations representing rural, peri-urban, and urban areas from November 2018 to June 2019. Samples were tested for prevalence of Salmonella spp, Escherichia coli, Vibrio cholerae. Samples positive for bacteria were tested for antimicrobial susceptibility through disc diffusion test. As a supplement to the analysis of samples, questionnaires to the vendors of the food products were made to provide background information. During 2020, statistical analysis of previously collected data and interviews with stakeholders working with AMR was made. The interviews aimed to serve as baseline information about current conditions regarding AMU and AMR. 320 cultivations of 1589 (20.1%) were positive for bacterial prevalence. 319 of these were tested for antimicrobial susceptibility where 203 (63.6%) were found to be multidrug-resistant (MDR) (resistant to three or more antibiotic groups). Furthermore, interviews with stakeholders stated that surveillance of AMU and AMR in Bangladesh is inadequate, especially within the animal and agriculture sector, and that a one health approach on a government level is needed to improve the situation. To be able to fully analyse the AMR situation in Bangladesh, a nation-wide study would need to be conducted, within all sectors, including both AMU and AMR testing.
