Planning, Projects, Practice : A Human Geography of the Stockholm Local Investment Programme in Hammarby Sjöstad
- 2006
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Programmes and policies to support ecological sustainable development and the practice of implementation is a question of innovation rather than known and taken for granted procedure. This thesis argues a priori models concerning stability in the social sciences, and human geography especially, are less able to help us understand this practice and planning in such unstable situations. Problematic in common understandings of planning and policy implementation concerning sustainability are the dualisms between physical-social spaces and between rationality-contingency. The first dualism makes it hard to grasp the interaction between humans and nonhumans. The second dualism concerns the problem of how to capture change without resorting to reductionism and explanaining the evolving projects as either technically, economically, or culturally rational. The scope of the thesis is to test resources from actor-network theory as a means of resolving these dualisms. The case is the Stockholm Local Investment Programme and the new district of Hammarby Sjöstad. The programme’s objective was to support the implemention of new technologies and systems, energy efficiency and reduced resource-use as well as eco-cycling measures. The case-study follows how the work with the programme unfolded and how administrators’ efforts to reach satisfactory results was approached. In doing this, the actors had to be far more creative than models of implementation and traditional technology diffusion seem to suggest. The recommendation is to take the instrumentalisation framing the plasticity of a project in planning seriously – as innovativeness is not a special but the general case. Hence, to broaden our tools and understanding of planning a human geography of planning projects is pertinent.

Substance flow analyses of metals and organic compounds in an urban environment : – the Stockholm example
- 2009
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- The intensified use of materials, products and goods in our time involves massive consumption of metals and organic compounds that can be released from society to the environment in the various stages of production, use and waste. Depending on the circumstances this may give rise to environmental risks, as metals in general and certain organic substances may be toxic in the short or long term. So where have those metals and organic substances been utilized? In which products or environments? Substance flow analysis (SFA) is a method to deal with these issues. The results from the analysis are quantifications of flows and stocks in a systematic way and within defined system boundaries.In this thesis four main research areas are identified, which need to be addressed. i) Application of SFA on substances that have not been studied in this respect before, which can give knowledge about flows and stocks related to consumption of goods. ii) Development of SFA to meet the needs in studies of trends for the substance cycles and studies of quantification of potential changes. iii) Assessment of which different agents and actions that induce the changes, such as chemical regulations, environmental objectives and aims. To what extent can these changes be related to substance flows? iv) Finally to assess, how can SFA be useful in environmental decisions? The specified aims focus on the metals antimony (Sb), cadmium (Cd), lead (Pb) and mercury (Hg) and the group of organic compounds alkylphenol/alkylphenol ethoxylates (AP/APEO), in urban environments, exemplified with case studies of Stockholm, the capital of Sweden.This thesis is a result of five studies. Three were based mainly on the methodology of SFA (Paper I-III). It has also been important to develop the chemical analysis of metals in goods where there has been a lack of information (Paper IV). Furthermore, assessment of policy questions and chemical regulations involve qualitative approaches and discussions (Paper I and V).The results show urban flows and stocks of the metals Cd, Hg, Pb and Sb and the group of organic substances AP/APEO. The results confirm that goods are important for the release of the substances studied. For Sb, emissions from brake linings (96%) dominate, but there are small emissions from textiles, potential emissions from flame retarded goods and probably small point sources. For AP/APEO the textile emissions were previously underestimated and the SFA presented here included this and pose textiles and cleaning agents as major emission source to wastewater.To repeat studies and to compare results from different years was a development of the SFA-method, which showed that Cd and Hg are being phased out as the inflow and stocks show diminished amounts, whereas the emissions remain approximately constant when comparing 1995 with 2002/2003. For Pb it is possible to talk about a phase-out of some specific goods, but not in general for inflow and stock.The changes in urban metabolism could be related to environmental decisions, e.g. effects of local initiatives and in some cases voluntary initiatives, but also as result of prevailing chemicals regulation. The utility of SFAs for decision makers may be related to methodological issues, such as the accounting approach. However, the utility was also found to depend on the structure of the monitoring, that is screening in the environment and concentration in wastewaters and sewage sludge precede the source mapping conducted with SFA. Substance Flow Analysis will likely continue to serve as the broad information tool for one substance at a time, which will offer source characterization of diffuse emissions in urban environments.

ORDO AB CHAO : Den politiska historien om biodrivmedel i den Europeiska Unionen – Aktörer, nätverk och strategier
- 2012
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Biodrivmedel blev efter millennieskiftet en alltmer prioriterad energikälla för EU och ansågs kunna stävja både klimathot och energissäkerhetsproblem samtidigt som drivmedelsproduktionen skulle gynna sysselsättningen i jordbruket. EUkommissionen formulerade 2007 ett mål om att ersätta 10 % av transportenergin till biodrivmedel. Snabbt uppkom dock en strid mellan en grupp av aktörer (miljörörelse och livsmedelsindustri) som såg biodrivmedelssatsningen som ett hot mot både miljön och livsmedelssäkerheten medan en annan grupp bestående av företrädesvis biodrivmedelsintressenter såg det som viktigt att behålla och utveckla EU:s mål för att rädda både klimat och miljö. Motsättningarna som uppkommit väcker frågor kring vilka logiker som legat bakom detta.Avhandlingens syfte är att analysera EU:s biodrivmedelspolicy, vilka aktörer och nätverk som har format denna process, vilka problem och lösningar som dessa aktörer och nätverk argumenterat för i processen, samt hur de har agerat för att mobilisera stöd för sina ståndpunkter. Detta har kopplats till teorier om nätverksstyrning, förekomsten av utlösande händelser i policyprocessen, resursberoende i nätverksmodellen samt på vilket sätt managementteori utövat inflytande. Metoden har varit att utifrån dokumentstudier rekonstruera det historiska förloppet och de aktörer som medverkat i processen.Avhandlingens visar att en förhållandevis liten grupp aktörer har haft ett stort inflytande över policyprocessen från det att problemen som biodrivmedel var satta att lösa definierades i slutet av 80-talet till det att hållbarhetsstandarder utvecklades och implementerades. Dessa aktörer har funnits i policynätverkens kärna och har som ett av sina centrala mål velat utarbeta globala regelverk för råvaruhandeln. De miljöorganisationer som medverkat i processen har genom resursberoenden till stor del varit underordnade denna grupp. Processerna har innehållit ett stort inslag av strategisk planläggning men även utlösande händelser som klimat- och livsmedelskriser har varit viktiga för att motivera politiska beslut.
