Show moreThis dissertation takes the reader around different Collective Food Procurement networks in Turin (Italy). Building on 15 months of ethnographic fieldwork between 2019 and 2020, I discuss the case of urban gardens (part one), open-air food markets (part two) and food aid initiatives (part three). I analyse related sites, people, practices and narratives and I call for diversifying our outlooks on urban peripheral areas and moving away from incautious optimism around widespread understandings of urban renewal and sustainability. To critically engage with these themes, I focus on civic engagement and morality, which represent red threads throughout the text. In particular, I argue that citizens’ engagement is increasingly mediated by the non-profit sector. This should be problematised in relation to silenced discontent, the exclusion of marginalised practices and limited citizens’ possibilities to be part of actual decision-making. I use morality as a common denominator to investigate the similarities and differences between the various cases - and examine their linkages with broader processes such as welfare reconfiguration, precarious labour and gentrification. I highlight how, through morality, certain working cultures, such as low remuneration as part of the non-profit sector, became interrelated with contemporary understandings of urban sustainability.

Show moreCotton — supplying approximately a quarter of global textile fibres — has various environmental impacts, including water use, toxicity, eutrophication and greenhouse gas emissions. In this Review, we identify these impacts across multiple life cycle stages. Environmental impacts at the cultivation stage depend on levels of irrigation, pesticide and fertilizer applications. At the textile manufacturing stage, impacts depend on energy infrastructure and manufacturing technologies. At the use phase, impacts depend on consumer habits related to buying, washing, drying and ironing. Depending on the impact category and country, cotton cultivation, manufacturing or use can dominate such impacts. For example, the use phase dominates greenhouse gas emissions in countries with carbon-intensive energy grids. Use of alternative fibres has the potential to reduce these environmental impacts, particularly jute and flax, which have much lower water demands. Opportunities for farmers, manufacturers and consumers to improve the environmental sustainability of cotton textiles include, among others, improving water-use efficiency in agriculture, innovative recycling and laundering less frequently. Future cotton sustainability assessments are needed to fill data gaps related to developing and emerging countries, the number of uses of a cotton garment and further environmental impacts such as salinization, as well as socio-economic impacts.The supplementary information is available here: https://static-content.springer.com/esm/art%3A10.1038%2Fs43017-023-00476-z/MediaObjects/43017_2023_476_MOESM1_ESM.pdf Show less

Show moreThis thesis investigates how the assessment of circular economy (CE) at the macro-economic level can be facilitated and promoted. First, a study on the socio-economic environmental impacts of international agricultural supply chain is presented to better exemplify how Multi-Regional Environmental Extended Input-Output (MR EEIO) data can be used to support policy making. Then, a Python software package (pycirk) and methods for standardized and replicable CE scenarios are presented with a case study on the global environmental and socio-economic impacts CE strategies. The thesis also presents an easy to use and open-source web-based tool for CE scenario construction and analysis (RaMa-Scene). Through these studies, MR EEIO appears to be an adequate tool to assess CE scenarios. However, the implementation of CE interventions will require a variety of micro-level changes across the current international production and consumption system and in many cases more detailed data is required than what is currently available in existing MR EEIO databases. Data availability for CE assessment could be increased through the use of Computer-Aided Technologies and Artificial Intelligence methods in combination with Life Cycle Inventory modelling and MR EEIO databases, but this is only one potential way forward. In fact, the industrial ecology and circular economy communities have many opportunities ahead to improve data collection practices by leveraging digital technologies and artificial intelligence methods. However, coordination in these scientific communities is needed to ensure that the full potential of these technological developments is harvested for the benefit of a sustainable circular economy and society.

Show moreThe European Union’s Green Deal and associated policies, aspiring to long-term environmental sustainability, now require economic activities to ‘do no significant harm’ to EU environmental objectives. The way the European Commission is enacting the do no significant harm principle relies on quantitative tools that try to identify harm and adjudicate its significance. A reliance on established technical approaches to assessing such questions ignores the high levels of imprecision, ambiguity, and uncertainty—levels often in flux—characterizing the social contexts in which harms emerge. Indeed, harm, and its significance, are relational, not absolute. A better approach would thus be to acknowledge the relational nature of harm and develop broad capabilities to engage and ‘stay with’ the harm. We use the case of European research and innovation activities to expose the relational nature of harm, and explore an alternative and potentially more productive approach that departs from attempts to unilaterally or uniformly claim to know or adjudicate what is or is not significantly harmful. In closing, we outline three ways research and innovation policy-makers might experiment with reconfiguring scientific and technological systems and practices to better address the significant harms borne by people, other-than-human beings, and ecosystems.

Show morePhysical activity is effective in preventing and treating many of these age-related diseases. However, two thirds of Dutch older adults do not reach the recommended level of physical activity. Current efforts to increase physical activity with professional led physical activity interventions are effective during the intervention period, but do not manage to have a sustainable effect. In this thesis we studied the possibility of peer coaching to sustainably increase physical activity in older adults. We do this by studying the effectiveness, implementation and organization of peer coach physical activity intervention. The conclusion of this thesis is that older adults can effectively and sustainably increase physical activity of older adults through peer coach physical activity interventions. After a small investment for implementation, a sustainable self-organising exercise intervention can be created which exist for years. The reach of the groups can be increased through an exercise referral scheme in primary care, but the effectivity needs to be improved through research. Nationwide implementation of exercise groups for older adults is possible, but it requires effort from a large (governmental) party. Show less

Show moreCo-production includes diverse aims, terminologies and practices. This study explores such diversity by mapping differences in how 32 initiatives from 6 continents co-produce diverse outcomes for the sustainable development of ecosystems at local to global scales.The promise of co-production to address complex sustainability challenges is compelling. Yet, co-production, the collaborative weaving of research and practice, encompasses diverse aims, terminologies and practices, with poor clarity over their implications. To explore this diversity, we systematically mapped differences in how 32 initiatives from 6 continents co-produce diverse outcomes for the sustainable development of ecosystems at local to global scales. We found variation in their purpose for utilizing co-production, understanding of power, approach to politics and pathways to impact. A cluster analysis identified six modes of co-production: (1) researching solutions; (2) empowering voices; (3) brokering power; (4) reframing power; (5) navigating differences and (6) reframing agency. No mode is ideal; each holds unique potential to achieve particular outcomes, but also poses unique challenges and risks. Our analysis provides a heuristic tool for researchers and societal actors to critically explore this diversity and effectively navigate trade-offs when co-producing sustainability. Show less

Show moreEcosystem service assessments rarely consider flows between distant regions. Hence, telecoupling effects such as conservation burdens in distant ecosystems are ignored. We identified service-providing species for two cultural ecosystem services (existence and bequest, and birdwatching) and two receiving, i.e. benefitting, regions (Germany, the Netherlands). We delineated and analysed sending, i.e. service-providing, regions on a global scale. The proportion of service-providing species with distant habitats was higher for birdwatching (Germany: 58.6%, Netherlands: 59.4%), than for existence and bequest (Germany: 49.3%, Netherlands: 57.1%). Hotspots of sending regions were predominantly situated in tropical and subtropical grasslands, savannas and shrublands and were significantly more threatened and poorer than the global mean. Hotspot protection levels for flows to Germany were higher than the global mean, and lower for the Dutch hotspots. Our findings increase understanding on how distant regions underpin ecosystem services and necessitate interregional assessment as well as conservation efforts. Show less

Show moreThe present study explores the role of water in the ancient Roman city of Ostia.In antiquity, Ostia was situated at the intersection of the Tiber River and the Mediterranean Sea, and acted as one of the harbour cities of Rome for several centuries.This study investigates how water was acquired, used, and drained away in Ostia, and how these systems changed over time. To achieve a high level of resolution, three city blocks (insulae), were selected as case studies: III, i; IV, ii; and V, ii.to contextualize these hydraulic systems, the present study developed a new methodology, the Roman Water Footprint. The method was inspired by 21st century ways of understanding how and why water is used in modern cities. These modern insights have indicated that sustainable water usage is based not only on advanced hydraulic technology, but also includes environmental factors, and a strong cultural factor.The results of the study indicate that Roman water usage was much more diverse and flexible than has been previously appreciated.By placing Roman water systems into dialogue with the methodologies of modern sustainable water research, this study forms an initial bridge between modern and ancient approaches to water and urbanism.

Show moreWetlands provide many ecosystem goods and services which include fish production. The sustainability of small-scale fisheries (SSF) has received considerable attention in recent years because fish is one of the major sources of animal protein to a considerable fraction of the global population which is estimated to increase to about 9.5 billion by 2050. Most of this attention has evolved around the pressures to which SSF are increasingly subjected, emanating particularly from population growth, rural poverty, weak institutional mechanisms, market forces, climate change among others. This thesis focuses on designing a sustainable management institution for the Elephant Marsh Fishery in Southern Malawi. With fieldwork which started in May 2011 to June 2013, this PhD study uses empirical data to understand the socio-ecological system of the Elephant Marsh Fishery and propose an actor-based institutional design which would achieve long-term sustainability of the fishery. After the introductory chapter 1, the second part of this thesis (Chapter 2) brings into perspective a clear understanding of the socio-ecological and land use setting of the Elephant Marsh as well as the ecosystem-based development potentials that exist at the wetland. The second chapter also highlights the actors and local institutions pertaining to the management of the wetland. Just like many similar ecosystems across the globe, the Elephant Marsh has come under increasing pressure in recent years which threatens the future of the wetland. Currently, Malawi does not have either a national wetland policy or a climate change policy and wetland issues are only marginally present in the National Parks and Wildlife Policy of 2000 and National Fisheries and Aquaculture Policy of 2001. As a result, the country lacks a framework that could be strong enough to achieve balanced and sustainable wetland management for multiple resource users. Chapter 2 of this study reveals that there are significant ecosystem-based development potentials at Elephant Marsh mainly in fisheries, recession agriculture, conservation, tourism and biomass for energy. Chapter 2 further shows that if these ecosystem-based development potentials are to be efficiently and effectively exploited at the Elephant Marsh, there is a need to rise above the institutional design principles of Ostrom which are based on nested enterprises and move towards real participatory approaches such as constitutionality (local people’s sense of ownership in bottom-up institution building). Certainly, as the present thesis suggests, there will be need to strike a balance between the local wetland management system, where pressure on the Elephant Marsh emanates mainly from poverty, and the national and international interests of biodiversity conservation as advocated by the Ramsar convention. Although enhanced production and maximum benefits from ecosystem good and services are central to any management system of the Elephant Marsh, it is important to realize that there are always limits to growth. Any management program for the Elephant Marsh should therefore strive towards sustainable exploitation of the opportunities that lie in the wetland’s goods and services. Globally, institutions that manage small-scale fisheries can be locally based, state controlled or of a mixed, cross-scale nature. The latter arrangement, widely known as co-management, is generally believed to be the preferred approach for fishery sustainability. In Africa, fisheries management faces many challenges due to unstable governance systems (weak states) whose role has evolved tremendously over the last century. The changes in the role of the state have mainly surfaced from a cautious realization that social actors (humans) respond to underlying incentives and are therefore central for any management system to work at all. With close reference to rich literature from across the globe, Chapter 3 of this thesis employs a crisp-set qualitative comparative analysis (csQCA) to examine cases of small-scale fisheries in several developing countries, in order to assess the degree of state involvement would be most relevant for designing a sustainable management for the Elephant Marsh Fishery. These degrees vary between: (a) strong top-down regulation irrespective of fishing community wishes, (b) a co-management mode of negotiation with fishing communities, (c) a merely supportive role of the state, or absence from the fishing scene. It was revealed that contrary to expectations, the sustainability of small-scale fisheries depended solely on the strength of collective social capital of the local communities at the resource scale. With weak local social capital, degrees of government involvement did not make any difference; the fisheries were unsustainable in all cases. The findings from this study have accentuated that the sustainability of SSF management in developing countries relies heavily on a strong collective social capital and a supportive government. Future practice and policy directions on fisheries management should understand the relevance of concrete community trust, networks, norms and values and strive to incorporate these in decision making and policy formulation. Governments, especially in developing countries, and their agents should realize the need to rise above the theoretical principles of “impose and control” and begin to take a more passive, non-conflictive position in designing working solutions for the sustainability of common pool resources such as small-scale fisheries. This can be done for example by encouraging civil engagement in transformative learning to reduce disadvantageous power differentials that exist in many fishing communities in developing countries. Chapter 4 uses the success and failure factors for SSF in developing countries which were identified in Chapter 3 to ascertain relevant factors for the sustainability of the Elephant Marsh Fishery. It is revealed that the Elephant Marsh Fishery sustainability depends on building strong local institutions with motivated leadership that can safeguard the interests of resource users. The present thesis therefore recommends that the government of Malawi should begin to take a more participatory position in designing locally crafted working institutions for the sustainability of common pool resources, such as small-scale fisheries at Elephant Marsh. In villages where fisheries fail due to weak local institutions or conflictive chiefs, the imposition of fishing rules is futile. The feasible government reaction then lies in (re)building collective social capital, especially the leadership of fisheries committees, and formally linking the established local institutions to the central government structure. In doing so an important inclusion would be the contextualization of key socio-causal dynamics of the management system at the Elephant Marsh. Cognizant of the importance of the socio-causal dynamics, Chapter 5 of this study used an actor-based framework (known as Action-in-Context) to unveil the issues that are crucial in devising a sustainable governance system for the Elephant Marsh Fishery. It was established that the key social variables for the designing a proposed three-pillared (locally based, weak and amorphous) resilient institution for sustainability of the Elephant Marsh Fishery are (i) the social reputation of the leaders of local fishery institutions and (ii) the power dynamics between traditional chiefs and these local fishery leaders. It is clearly evident from the present study that an actor-based multi-level analysis of rules and other mechanisms prevailing in a fishery can be instrumental in designing a cost-effective institution for the near future. For the design of longer-term institutional options, the assumptions underlying the actors-based method (Action-in-Context in our case) become weaker, e.g. because new types of actors may move in or because actor capacities and motivations may change or become more intertwined. This then necessitates a stronger reliance on both institutional theory and frameworks or (as has been my choice) the design of a flexible process of institutional development guided by an adaptive, learning organization. The last section of thesis (Chapter 6) synthesizes the main findings and proposes what needs to be done in designing a resilient management system for the Elephant Marsh Fishery. This PhD thesis ends by stimulating a style of thinking that may be fruitful for institutional science in general. Show less

Show moreEco-innovation often underperforms due to behavioral and systemic responses to technical change leading to additional demand and environmental damage. This paradox, also known as the rebound effect, has puzzled for decades scholars from a myriad of disciplines, mostly due to the profound implications for achieving environmental targets. Within the different disciplinary understandings, concepts and methods from the industrial ecology domain offer unexplored potential for the study of the rebound effect. The transport sector, a vital engine of social progress and historically at the spotlight of environmental policy, is a perfect case study to unveil such potential. The aim of this dissertation is to investigate the role of rebound effects in shaping the environmental performance of transport eco-innovation, and to investigate the value of applying concepts and methods from the realm of industrial ecology and other sustainability sciences. Through case studies, the value of this renewed perspective – the environmental rebound effect– is confirmed in the context of complex sustainability issues. Show less
