Toward Cyborg PPGIS : exploring socio-technical requirements for the use of web-based PPGIS in two municipal planning cases, Stockholm region, Sweden
- 2017

In: Journal of Environmental Planning and Management. - : Routledge. - 0964-0568 .- 1360-0559. ; 60:8, s. 1366-1390

Journal article (peer-reviewed)abstract
- Web-based Public Participation Geographic Information Systems (PPGIS) are increasingly used for surveying place values and informing municipal planning in contexts of urban densification. However, research is lagging behind the rapid deployment of PPGIS applications. Some of the main opportunities and challenges for the uptake and implementation of web-based PPGIS are derived from a literature review and two case studies dealing with municipal planning for urban densification in the Stockholm region, Sweden. A simple clustering analysis identified three interconnected themes that together determine the performance of PPGIS: (i) tool design and affordances; (ii) organisational capacity; and (iii) governance. The results of the case studies augment existing literature regarding the connections between the different socio-technical dimensions for the design, implementation and evaluation of PPGIS applications in municipal planning. A cyborg approach to PPGIS is then proposed to improve the theoretical basis for addressing these dimensions together.

Managing multiple risks in land use planning – a literature review
- 2020
-
In: Proceedings of the 30th European Safety and Reliability Conference and the 15th Probabilistic Safety Assessment and Management Conference. - Singapore : Research Publishing Services. - 9789811485930 ; , s. 572-579
-
Conference paper (peer-reviewed)abstract
- Many risks addressed in land use planning, such as flooding and accidents involving hazardous materials, have widely different characteristics which makes them difficult to compare. Yet, these risks sometimes need to be considered together in order to support decision-making. Furthermore, risks can sometimes affect each other, which differentiate the land use planning context from situations where single risks are addressed. This literature review investigates what characterize the methods proposed in the scientific literature that deal with the challenges of multiple risks and interests in land use planning, and to what extent they are applicable for Swedish detailed development plans. None of the identified methods could consider several types of consequences, or other interests, while at the same time compare risk levels between areas and evaluate acceptability. Neither were there any suggestions on how to consider interactions between risks in a way that was applicable to Swedish land use planning. All articles were aimed at proposing methodologies for assessing risk or hazards and there was little emphasis on how an assessment, or several assessments, should be implemented in a decision-making context. There is need for further studies on how multiple risks are managed in practice and what could be learned from other fields.

Regionens täthet och grönstrukturens potential : Det suburbana landskapets utvecklingsmöjligheter i en växande storstadsregion
- 2008
-
Reports (other academic/artistic)abstract
- Av de två fallstudierna kan flera viktiga slutsatser dras av betydelse för den regionala planeringen. Vi kan konstatera att stadsnaturen utgör en viktig del av stadsutvecklingen och därmed också hälsa, demografi och samhällsekonomin på många nivåer. Då stadsplaneringen i högsta grad påverkar såväl bebyggelse som grönstruktur måste den på ett tydligare sätt integreras i regionplaneringen och strukturalternativ, särskilt i det inre förortslandskapet. I rapporten presenteras flera användbara mått på integrationen mellan grönstruktur och bebyggelse, såsom tillgänglighet, kompakthet och rymlighet. Vidare ges exempel på konceptverktyg, resiliens, läsbarhet, och tillgänglighet, som syftar till att tydliggöra grönstrukturens potential. Dessa konceptverktyg kan också upphäva polariseringen inom planeringsdiskursen och skapa överlagringar av värden och funktioner i grönstrukturen och landskapet som helhet. För att hantera den växande staden behövs ett nytt integrerat synsätt på grönstrukturen i staden. Kort sagt; staden förutsätter grönstrukturen och grönstrukturen förutsätter staden. Vi talar således mer om ett beroendeförhållande snarare än ett motsatsförhållande. I ett övergripande strukturellt perspektiv menar vi att städer alltid har växt och gör det fortfarande efter principen att maximera kompaktheten i centrum och maximera rymligheten i periferin (fig 4.2). Denna process sker inte automatiskt utan måste undersökas och styras genom regional och kommunal fysisk planering. En helt fri marknad riskerar att leda till ineffektivitet och orättvisor. Offentliga nyttigheter som trafik- och grönstrukturer måste utvecklas och förvaltas i en demokratisk process. Att inte låsa landskapet i ett bevarande utan att utgå från landskapets utvecklingsmöjligheter torde vara ett i grunden demokratiskt förhållningssätt till planering och landskapsdesign, därför att det utgår från hur miljön kan förbättras för allmänna och enskilda intressen. För detta nya förhållningssätt krävs nya begrepp och planeringsverktyg.

The willingness to pay for urban sustainability
- 2013
-
In: 2013 International Space Syntax Symposium. - : Sejong University Press. - 9788986177213
-
Conference paper (peer-reviewed)abstract
- Quite recently certification systems for sustainable development of neighborhoods and communities, such as L EED ND and BREEAM for Communities, came to the market. These systems try to define urban sustainability through sets of criteria that in a variety of ways measure aspects in urban developments that have an influence on environmental, social and economical issues on a local level. This paper investigates the monetary values on these criteria, derived from property prices from apartments and single family houses in Copenhagen. In order to make proper estimates on the monetary values for certification criteria a hedonic price model is used. The model holds property prices from about 20 000 sales as dependent variable which is then correlated, through multiple regressions, with variables made out of the criteria through GIS-analyses. Translation from certification criteria into measurable variables is done with great consideration to contemporary urban theory. These variables are results from spatial analyses based on space syntax and other more standard spatial measures. The certification systems focuses on neighborhoods and communities, which is considered in the radiuses used for analyzing. It turns out that 19 of the 30 measured criterions are statistically significant, but a majority shows negative correlations to price. It is also acknowledged that space syntax measures like integration and betweenness have an influence on prices. Local integration, used as a proxy for various urban qualities, is shown to have a negative impact on prices. Qn the contrary, betweenness on a global scale is valued as positive. From these results the conclusion is that people are generally not willing to pay for urban sustainability on the local scale, as defined in LEED and BREEAM certification systems. However, it is furthermore argued that this is a question of measure and definition. Previous studies, e.g. (Spacescape and Evidens 2011) and (Sjaastad et al. 2007), imply that many of the measures used in this study are positively correlated to price if done on a global scale. It is concluded that the urban sustainability should to be examined further before rejecting the hypothesis that it has positive monetary value.

Architectural Knowledge and Complex Urban Space : Analysis of Five Proposals for Slussen in Stockholm
- 2010
-
In: Journal of Space Syntax. - 2044-7507. ; 1:1, s. 177-198
-
Journal article (peer-reviewed)abstract
- This paper presents, compares and evaluates five design proposals for remodelling the famous, or as some would say infamous, Slussen transport interchange in the Swedish capital, Stockholm. Slussen is strategically located where the locks between Lake Mälaren and the Baltic Sea meet the land bridge between northern and southern Sweden. It is now a major hub for Stockholm's road, bus, boat, rail and underground transport systems, which in 1935 was redesigned as integrated transport node in the modernist style. This has now become so physically deteriorated and obsolete that a series of proposals were put forward during the opening years of the new millennium for its complete remodelling. As a contribution to that exercise, the urban design practice Spacescape was commissioned to analyse and evaluate the likely performance of the various regeneration proposals for Slussen, using methodologies based on space syntax theory and other methods, in order to predict the likely outcome of each proposal on Stockhlom's urban life. In what follows, projects by Atelier Nouvel and Habiter Autrement, Big, Foster and Partners and Berg, Nyréns and finally Wingårdh and Tema have been compared and evaluated in the light of the goals set out in Stockholm's comprehensive city plan.
