The aim of this thesis paper is to integrate three important thematic aspects i.e., improve qualities in the urban ecological situation, provide ideas for handling stormwater flooding and ideas to improve socio-economic aspects for inhabitants. The integration of ideas is illustrated in a masterplan program-sketch in three phases. Dhaka is the capital of Bangladesh. Dhaka is a densely populated fast developing city. The chronological changes of the natural setting due to rapid growth of urbanization in Dhaka city creates an imbalance with nature and disrupts urban ecology. The green and blue structures are replaced with built areas and hard surfaces. The situation for urban ecology in the city of Dhaka affects storm water flooding and social wellbeing. The methods used for background knowledge to this proposal are literature reviews, document searches, interviews, GIS analysis and a study of role models from different countries and contexts where a variety of solutions, proposals and functions inspired me in my own sketching. The methods and the background for this thesis were used to formulate guidelines to support the overall program-sketch for the three phases in a masterplan. The first phase program-sketch includes redesigning the informal settlements in Karail into better living conditions for the dwellers according to Patrick Geddes theories by keeping the overall road- and block structure and provide new shelter, job opportunities and adding recreational values to the area. The second phase concentrated on re-establishing of water streams in a green park according to the philosophy of Fredrick Law Olmsted, and in the third phase the former airport Tejgaon to become a large green area for social meetings, recreation activities for the Dhaka city inhabitants and provide job opportunities for the informal dwellers. The discussion on strengths, limitations, challenges, and further development ends with a conclusion that it is of great importance to work integrated with the three thematic aspects urban ecology, storm water flooding and social wellbeing on an overall level and with understanding of the issues among both specialists, politicians, and inhabitants to be able to implement necessary change towards sustainability.

Social sustainability in urban places is undervalued in urban planning due to the intangible nature of the concept. By valuing lived experiences of place, this research connects social and environmental sustainability pillars to support planning for socioenvironmental justice from a citizen's perspective. The quality of the urban outdoor environment is explored in relation to safety and individual and collective efficacy for social wellbeing which contextualises the role of urban green space. This study suggests socio-environmental sustainability is related at an individual and collective level. Safe social environments can support place attachment processes and safe green spaces can support self-regulation of emotions that influences behaviours. The urban outdoors can be viewed as a social learning environment. An inductive interpretative phenomenological analysis (IPA) led enquiry has been conducted which suggests urban places for social wellbeing can be explained by a framework that integrates social and environmental psychology and spatial politics theories. This study suggests that place attachment is at the heart of dynamic social environments and influences social learning behaviours through vicarious learning and the manifestation of social spaces as framed by Scannell and Gifford's Tripartite Framework of Place Attachment, Bandura's Social Cognitive Theory and Lefebvre's Theory of Produced Social Space. Designing for socio-environmental justice is associated with understanding human irrationality due to poor social and environmental quality. This research suggests the right to feeling safe and the quality of the urban environment, including safe green spaces, becomes an issue for the operation of democracy and facilitating self and collective efficacy, by recognising the invisible bricks that form urban places for social wellbeing.

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.

This essay will focus on experiences from previous research projects and aster courses with the aim of highlighting some core issues and problems regarding large scale infrastructure projects, landscape assessment and compensation measures, especially concerning cultural values in the agricultural landscapes of Scania, the southernmost part of Sweden. Problems, but also possibilities, related to evaluation, mitigation and compensation are discussed. Landscape Observatories as established under the European Landscape Convention are introduced as a possibility for trans-organizational learning around landscape matters in a broad sense. It is concluded that regional landscape observatories could function as hubs for more efficient management of large-scale landscape interventions and contextually relevant mitigation and compensation measures. Incremental changes in the present legislation and administration, which seems to be the prevalent strategy, might not be sufficient in order to safeguard our cultural heritage or be in line with the objectives of international agreements

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.

This thesis presents and asseses a method for participation in landscape planning and management. The method has a long-term perspective, while focusing on the interests of local stakeholders. Public participation has been recognized as a fundamental part of landscape planning and management. Through for example the European Landscape Convention's (ELC) inclusive definition of "landscape", landscape got a more democratic connotation where focus is put on people's perception of a landscape. This shift calls for more collaborative working methods requiring more and somewhat different skills from the professional planner than a traditional top-down system does. The research presented in this thesis is context-bound, and based on action-oriented working methods and approaches where citizens, planners and managers are involved in parallel. Academia, represented by researchers and students, is proposed to supplement and assist municipal authorities and the local society in collaborative planning. Methods and approaches related to awareness raising, embodied knowledge, strengthening people's relationship to their everyday landscape and identifying ways of letting local experts' voices be heard in the municipal planning process, have guided the research. All the cases presented, describe planning processes in peri-urban landscapes, at different scales with strong connection to nature reserves, changed patterns of land use, and with varying amounts of stakeholders directly related to the landscapes in question. Three cases were selected to discover, design and investigate potentials with the "connoisseur methods", and three cases were selected to test and refine the method, anchored in current municipal planning and resulting in actual plans. In this thesis 'The connoisseur method' is proposed as a way to achieve better collaborative planning. It invites a new type of expert to influence landscape development: the connoisseur is an expert in experiencing the landscape from her particular perspective, and represents the local society. The method proposed is a mix of different participatory methods used for landscape analysis as a way for the professional planner/manager to understand how the local community understands and uses different landscape features. The results of the different cases show how the process is of vital importance. A successful collaboration process is a valuable tool for learning, both locally among the connoisseurs and amongst the municipal planners and managers.

Within urban design there is increasing interest in the close relationshipbetween social, economic and political processes and the production of public spaces. Thisrelationship, however, often remains abstract and is rarely illustrated in empirical studies.This paper introduces an institutionalist understanding to the production of public spaces,whereby emphasis is placed on the analysis of structuring forces and actors as a way toapprehend the complexity of the social processes guiding and influencing the planning,design and management of public spaces. The institutionalist understanding is illustratedin the case study of an urban renewal project in Barcelona. The results of the case studyshow the contrasts and tensions between the structuring forces and the different actorsoperating in the project, how structuring forces favoured the interest and claims of someactors over those of others, and the potential risks and challenges that this has for the useand value of the public spaces produced by the project.

Many urban trees are located on private property in residential areas, but these trees are infrequently included in urban forest strategies and plans, meaning that for most local governments, the complete urban residential tree population, its potential for supplying ecosystem services and its dynamics are unknown. This thesis examined the assessment methodologies of ecosystem services provided by trees in the attempt to provide valuable information about residential trees. The abundance of trees on individual residential properties was tested against potential decision-driving variables, collected using field work, remote sensing, questionnaire surveys and spatial property information. While residents reported positive attitudes to trees and benefits they provide, this did not necessarily result in greater tree abundance on individual properties. It was found that long-term of validation of sampling methods is required for monitoring of urban trees. Remote sensing could be seen as a reliable and non-invasive way to determine canopy cover using publicly available information in residential areas. This thesis improved understanding of residential urban trees and the ecosystem services they provide as the part of the urban forest. These assessment should include social and spatial variables influencing their development to allow residential trees to become integrated into local governance arrangement structure in order to develop informed management approaches for the entire urban forest.

This article brings together the concepts of land and landscape, tightly linked in urban transformative situations, but rarely used for the purpose to strengthen strategic planning for sustainability. They are investigated as a combined base for land use deliberations, in early phases of planning processes, in practices of different scale, especially in a European context, drawing on planning and landscape policies generally agreed upon, as well as the UN Sustainable Development Goals. This article argues for taking into consideration the landscape as experienced human habitat, in relation to the understanding of land as both a common resource, and as pieces of property. This is motivated partly by the more or less global political trend and the turn from state interventions to individualistic capitalism (calling for new methods to solve common challenges), but also by a changing planning profession, increased collaborative planning processes, increased significance of public space as a scarce resource in densified cities, the need for holistic perspectives in sustainable urban development and the need for unifying concepts for urban and rural land at a local and regional scale. A new concept "around-scape" is suggested, in order to make visible the subjective binding between available perceived resources and spatial transformation.

Sverige är ett relativt glesbefolkat land med tillsynes gott om mark att bygga på. Medan det funnits perioder då jordbruksmarkens bevarande lyfts i den politiska diskussionen, har inget lagstadgat skydd för jordbruksmark införts. För närvarande tycks jordbruksmarken i samhällsplaneringen åter blivit mer aktuell. Städer i många länder och även svenska kommuner ser sig om efter alternativ till glesa och markkrävande utvecklingsplaner. Syftet med denna orienterande studie var att undersöka hur bevarandet av god jordbruksmark värderas i relation till exploatering inom kommunal översiktlig planering, och att se med vilka strategier/policyer och metoder som detta hävdas. Studien har bedrivits som ett samarbete mellan jordbruk och bebyggd miljö inom SLU:s program för Fortlöpande Miljöanalys.

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'.

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.
