This article provides a nano (hyperlocal) view of climate change mitigation by viewing regenerative organizing through the eyes (as well as bodies and senses, etc.) of the households engaged in community-based energy projects. By showing what humans make up for in the largely absent relationship between nature and technology in these projects, we envision an incremental extension of the literature on community-based energy. The radically different contribution we aim to make is a tripartite imbrication that brings in natural agency alongside the human and the technical but specifies precisely how nano (smaller than micro) embodied practices afford mis- and realignments. https://doi.org/10.1177/1086026619886841 LinkedIn: https://www.linkedin.com/in/helenkopnina/

The relevance of citizen participation in regeneration projects, particularly in shrinking cities, is widely acknowledged, and this topic has received a great deal of policy and academic attention. Although the many advantages of citizen participation in regeneration projects have been identified, its current forms have also received considerable criticism. In short, this criticism boils down to the conclusion that the ideal of citizen participation is not put into practice. This paper considers why this is the case, asking whether current participatory practices enable citizens to exercise influence as political actors in urban regeneration projects. In this paper, we examine this question based on Mouffe’s conception of the political, coupled with findings from our empirical research conducted in Heerlen North, The Netherlands. We conducted qualitative research on urban regeneration in the shrinking old industrial city of Heerlen. The findings reveal two distinct perspectives on citizen participation. Professionals see the existing context of citizen participation as a reasonable and practical but, in some respects, insufficient practice. Citizens’ views on participation are organized around feelings of anger, shame, and fear and are grounded in experiences of a lack of recognition. These experiences limit citizens’ abilities to exert true influence on regeneration projects. We conclude that efforts to regenerate shrinking cities should strive to recognize these experiences so as to create conditions that generate respect and esteem and, as such, enable urban social justice.

This article presents a case study on the implementation of the Thames Estuary 2100 Plan in the Royal Docks, a regeneration project in the East of London. On paper, the Thames Estuary 2100 Plan advances the shift from traditional flood control to flood resilience, because of its long-term horizon, estuary-wide approach, and emphasis on floodplain management. In practice, however, we identify three frictions between vision and reality: a lack of local ownership of the plan, a lack of clear guidance for floodplain management, and limited capacities with local authority. These frictions suggest an ongoing ‘public-public divide’ in decentralized governance.

Mexican oregano is a non-timber forest product harvested in natural vegetation and represents an important source of income for rural families. Recent reports have highlighted decreases in natural populations caused by increased harvest intensity. Oregano leaf harvesting is a complex problem, involving different components and views, and has a clear spatial dimension. We proposed an analytical framework based on multi-criteria-multi-objective analyses. GIS tools were used as the platform for managing, displaying and analyzing ecological and socioeconomic information from different sources in order to evaluate land suitability of three different management strategies for two competing land objectives: oregano Harvest and oregano Regeneration. The incorporation of environmental evaluation criteria in the analysis allowed the identification of new potential oregano harvesting areas which were neither reported by harvesters, nor registered during harvesting trips. Socio-economic criteria, such as land tenure, highlighted the fact that a substantial proportion of current oregano harvesting areas are located outside ejido limits resulting in potential conflicts for resource access. The proposed Balanced oregano management strategy, in which the same proportion of suitable area (50%) was assigned to both objectives, represents the most favorable management strategy. This option allows harvesters to continue earning an income from oregano leaf harvest; and at the same time helps in the selection of the best areas for oregano regeneration. It also represents a management strategy with a smaller impact on oregano populations and on the harvesters ́ income, as well as lower monitoring costs. The proposed analytical frame-work may contribute to advance the application of systematic approaches for solving decision-making problems in areas where oregano leaves and other NTFP are harvested.

At the age of a failing economic system and undeniable evidence of the effects humankind has had over the planet, it is necessary to look for alternatives to the way we live locally. This article explores the use of designing narratives and metanarratives to co-create imaginaries serving as the needed alternatives. This research starts by considering the historical factors to understand how industrialisation and the loss of traditional practices created a culture of disconnection from Nature in the Girona area, but also looks at why people start now reconnecting with it. The analysis is the foundation for speculative design practices to co-create a new local narrative of connection and regeneration. The project adopted the Integrative Worldviews Framework and used paradoxes to create possible future worldviews based on historical factors and literature. Citizens participated in conversational future-visioning workshops to develop and evaluate their local imagery of the previously created worldviews. This conversation-based exercise evidenced the potential of paradoxes in destructive futures to create imaginaries of regeneration. These imaginaries merge and form future stories. From the future narratives, the practice created cultural artefacts embodying a new culture of connection based on storytelling, traditional jobs, and a mythological understanding of Nature. Finally, as observed at the end of the project, these artefacts allow citizens to adopt them as their culture and expand their current worldview.

This report serves as one of the two background documents for the HvA/UvA research proposal concerning cultural interventions in the process of urban regeneration in Krachtwijken in Amsterdam. The report at hand, based on a review of the international literature on art and regeneration, and on international and Dutch practices, shows why the proposed research will be both valuable to the practice of Amsterdam and to international research. The report starts with a description of the role of the arts in urban regeneration (§2) and the objective of regeneration processes: ‘feeling at home’ (§3). Next, paragraph 4 further explores the role of the arts in urban regeneration by focussing on the forms and impacts of and critique on different cultural interventions. Finally, §5 summarises the preconditions for effective cultural interventions. This general overview of the functions of cultural interventions in the urban context provides the background against which our research agenda is presented.

The catalytic conversion of oleic acid to aromatics (benzene, toluene, and xylenes, BTX) over a granular H-ZSM-5/Al2O3 catalyst (ϕ 1.2–1.8 mm, 10 g loading) was investigated in a continuous bench-scale fixed-bed reactor (10 g oleic acid h–1). A peak carbon yield of aromatics of 27.4% was obtained at a catalyst bed temperature of 550 °C and atmospheric pressure. BTX was the major aromatics formed (peak carbon yield was 22.7%), and a total BTX production of 1000 mg g–1 catalyst was achieved within a catalyst lifetime of 6.5 h for the fresh catalyst. The catalyst was deactivated due to severe coke deposition (ca. 22.1 wt % on the catalyst). The used catalyst was reactivated by an ex situ oxidative regeneration at 680 °C in air for 12 h. The regenerated catalyst was subsequently recycled, and in total, 7 cycles of reaction-regeneration were performed. A gradual decrease in the peak carbon yield of BTX was observed with reaction-regeneration cycles (e.g., to 16.3% for the catalyst regenerated for 6 times). However, the catalyst lifetime was remarkably prolonged (e.g., >24 h), leading to a significantly enhanced total BTX production (e.g., 3000 mg g–1 catalyst in 24 h). The fresh, used, and regenerated catalysts were characterized by N2 and Ar physisorption, XRD, HR-TEM-EDX, 27Al, and 29Si MAS ssNMR, NH3-TPD, TGA, and CHN elemental analysis. Negligible changes in textural properties, crystalline structure, and framework occurred after one reaction-regeneration cycle, except for a slight decrease in acidity. However, dealumination of the H-ZSM-5 framework was observed after 7 cycles of reaction-regeneration, leading to a decrease in microporosity, crystallinity, and acidity. Apparently, these changes are not detrimental for catalyst activity, and actually, the lifetime of the catalyst increases, rationalized by considering that coke formation rates are retarded when the acidity is reduced.
