Die nachhaltigkeitsorientierte Transformation von urbanen Räumen ist eine akute Herausforderung. In den letzten Jahren haben koproduktive, experimentelle, transdisziplinäre und häufig informelle Stadtwandelprojekte als Such- und Lösungsräume hohe Sichtbarkeit erlangt. Schlüsselakteure hierfür stellen - so die These - Verwaltungsvertreter:innen einer integrierten Stadtentwicklung und -planung, Wissenschaftler:innen einer transformativen Forschung sowie zivilgesellschaftliche Stadtmacher:innen dar. Die Autor:innen, verankert in diesen drei Gruppen, kritisieren die häufig nur situative Zusammenarbeit dieser drei Akteursgruppen. Ein Modell der Zusammenarbeit im Spannungsfeld zwischen Gemeinsamkeiten, jeweiligen Potentialen und herausfordernden Eigenlogiken der Akteurssysteme wird entwickelt. Darauf aufbauend wird vorgestellt, wie durch strategischen Trialog und reflexive Lernprozesse die Zusammenarbeit verbessert und die Wirksamkeit koproduktiven und experimentellen Stadtwandels erhöht werden kann.
This article enriches the existing literature on the importance and role of the social sciences and humanities (SSH) in renewable energy sources research by providing a novel approach to instigating the future research agenda in this field. Employing a series of in-depth interviews, deliberative focus group workshops and a systematic horizon scanning process, which utilised the expert knowledge of 85 researchers from the field with diverse disciplinary backgrounds and expertise, the paper develops a set of 100 priority questions for future research within SSH scholarship on renewable energy sources. These questions were aggregated into four main directions: (i) deep transformations and connections to the broader economic system (i.e. radical ways of (re)arranging socio-technical, political and economic relations), (ii) cultural and geographical diversity (i.e. contextual cultural, historical, political and socio-economic factors influencing citizen support for energy transitions), (iii) complexifying energy governance (i.e. understanding energy systems from a systems dynamics perspective) and (iv) shifting from instrumental acceptance to value-based objectives (i.e. public support for energy transitions as a normative notion linked to trust-building and citizen engagement). While this agenda is not intended to be—and cannot be—exhaustive or exclusive, we argue that it advances the understanding of SSH research on renewable energy sources and may have important value in the prioritisation of SSH themes needed to enrich dialogues between policymakers, funding institutions and researchers. SSH scholarship should not be treated as instrumental to other research on renewable energy but as intrinsic and of the same hierarchical importance.
Food production is responsible for approximately 17% of Germany's greenhouse gas (GHG) emissions. After retail, out-of-home catering is the second largest food sales channel in Germany. A variety of means on both the supply and demand side are necessary to stimulate, facilitate and encourage a more sustainable development and minimise GHG emissions in this sector. Nudges are one of these. This paper's focus lies on the demand side. Set in real-world laboratories, we use a standardised empirical approach to compare different nudging interventions belonging to the area of physical environment and consumers’ choice making process. We compare the effects of the same intervention across different settings and the effect of different, sequential nudging interventions in the same setting. Data was collected in eight workplace and school cafeterias in Germany over two project iterations (2016/2017; 2019/2020). A similar intervention design was applied. Comparability was assured by a harmonised menu. The first project iteration revealed that only one nudge (top menu position, +22.5%) led to significant increases in sustainable food choices, while results from the second iteration showed that all nudge interventions (best counter position, +11.6%; top menu position, +6,9%; label plus information, +15.9%) positively influenced consumer choice. Possible explanations such as the stricter compliance to the experimental design in the cafeterias but also societal developments such as the appearance of the Fridays for Future movement are discussed. As results vary between specific locations and settings, our findings suggest that nudges need to be adjusted to situational conditions for achieving highest efficacy.
The COVID-19 pandemic has affected human mobility via lockdowns, social distancing rules, home quarantines, and the full or partial suspension of transportation. Evidence-based policy recommendations are urgently needed to ensure that transport systems have resilience to future pandemic outbreaks, particularly within Global South megacities where demand for public transport is high and reduced access can exacerbate socio-economic inequalities. This study focuses on Metro Manila - a characteristic megacity that experienced one of the most stringent lockdowns worldwide. It analyzes aggregated cell phone and GPS data from Google and Apple that provide a comprehensive representation of mobility behavior before and during the lockdown. While significant decreases are observed for all transport modes, public transport experienced the largest drop (-74.5 %, on average). The study demonstrates that: (i) those most reliant on public transport were disproportionately affected by lockdowns; (ii) public transport was unable to fulfil its role as public service; and, (iii) this drove a paradigm shift towards active mobility. Moving forwards, in the short-term policymakers must promote active mobility and prioritize public transport to reduce unequal access to transport. Longer-term, policymakers must leverage the increased active transport to encourage modal shift via infrastructure investment, and better utilize big data to support decision-making.
Aufbruch zur strategischen Autonomie der EU in der Kriegsführung mit Mitteln wirtschaftlichen Zwangs
(2021)
Die geopolitische Situation ist im Umbruch. Wir sind im Übergang zu einer multipolaren Situation, die Hegemonialkonkurrenten organisieren sich in Blöcken. Die Stratifizierung des Raumes der Wirtschaft, "Globalisierung" genannt, verliert ihre Basis, die strikte Trennung von der Politik der Hegemonialkonkurrenten. Wirtschaft wird nun in Dienst genommen für politische Ziele. Das erfordert Aufrüstung in Mitteln der Wirtschaftskriegsführung. China und die USA sind darin weit vorangegangen. Die EU hat entschieden, ihrerseits nachzurüsten, um auf Augenhöhe zu kommen.
Die Transformation des Wirtschaftens, wie sie der Green New Deal vorsieht, steht vor einem vierfachen Risiko: Dies bezieht sich auf die Transformationstiefe, den wissenschaftlichen und politischen Androzentrismus, die Gender-Mainstreaming-Gebote und die nötige Effektivität und Akzeptabilität der Transformation. Die hier dargelegte These ist, dass es unverzichtbar ist, im Transformations-Konzept selbst die strukturellen Ursachen von Ungleichheiten geschlechtergerechtigkeitswirksam zu adressieren. Wie am Beispiel der Verkehrswende gezeigt wird, ist dies die Voraussetzung dafür, ökonomisch-sozial-ökologische Zusammenhänge zu erkennen und die Klima-, Ressourcen- und ökonomischen Krisen entsprechend politisieren zu können.
There is urgent need to change the way we make use of non-renewable resources, especially metals, to sustain their availability for vital technologies associated with achieving change towards sustainability, but also to minimize negative impacts and to achieve a fair distribution of the wealth and burdens associated with their production and use. Especially public actors (state governments and administrations) have recently formulated strategies as a means to guide action fostering these goals. Yet, these strategies are very different in their character, which makes it difficult to compare them and learn how to best design strategies for a given context to contribute to the necessary change. To approach this question, we analyzed 37 national mineral resource-related strategy documents worldwide concerning their contextual conditions, motivation, and objectives. Following the general inputs for transition strategies (current and target state, transition strategy), we identified four clusters of strategy documents that share similarities in their approaches and support the development of specific recommendations for future strategy design in terms of both content and process. Designing strategies with a clear structure that interlinks a systems-based description of the current state, a clear vision (oriented at sustainability principles) and a sufficiently differentiated but at the same time flexible transition pathway improves their potential to contribute to more sustainable metal production and use.
Während Fragen der Wertbildung meist als ökonomische behandelt werden, wird in diesem Beitrag der Prozess der Wertbildung politisch und ökonomisch verstanden. Ein Prozess, der von Herrschaft geprägt und doppelseitig ist: Bewertung ist mit Entwertung ebenso verbunden wie die Eingrenzung der Einen mit der Ausgrenzung der Anderen. Diesen Mechanismus nennen wir "Externalisierung als Prinzip". Die politik- und wirtschaftswissenschaftliche Konstruktion des externalisierenden Prinzips und die Herrschaftsformen seiner auch gewaltsamen Durchsetzung werden ideen- und theoriegeschichtlich bearbeitet. Feministische Analysen der klassischen Vertragstheorien und der Politischen Ökonomie zeigen: Die bürgerliche Gesellschaft und ihre Ökonomie werden durch Trennungen geprägt. Das wertvolle Dazugehörige ist angewiesen auf das als wertlos Ausgegrenzte. Es wird deutlich, dass die Geschichte mit der klassischen politischen und ökonomischen Theorie nicht zu Ende ist, sondern dass bis heute herrschaftsförmige Be- und Entwertungen als Mittel zur Krisenbewältigung eingesetzt werden.
Responsible consumption and production is one of the Sustainable Development Goals of the United Nations. To achieve this goal the currently high extraction rates of natural resources, that our economy is based on, needs a transformation of the consumption and production system considering technological as well as social change. One of the promising transition approaches is seen in collaborative consumption with its many facets of socio-cultural innovations and fast growing number of participants and businesses. With a decreasing production of goods, due to a utilisation of underutilised assets, these offers might support an absolute reduction of the global resource use. However, a positive environmental effect depends on the setting and the social practices of such sharing offers and is not sustainable or resource efficient generally. Also, resource efficient practices with a low diffusion potential that stick in a niche offer no leverage to achieve sustainable consumption patterns. Thus, this paper describes a mixed method approach to analyse the resource efficiency and diffusion potential of 20 sharing offers in the area of mobility, housing & travel and everyday objects in Germany. Results show that the overall positive environmental connotation of sharing offers cannot be confirmed. We identified five clusters of offers that are all treated to be differently when it comes to deploying the positive potential and avoid unnecessary societal effort to achieve the mentioned Sustainable Development Goal.
