- Parks and private and public gardens do not exist in isolation, but form part of the urban fabric, contributing to ecological functioning. There is growing interest in how civil society shapes urban ecologies and vegetation patterns. This paper explores the ecological outcomes of a series of indigenous plant greening interventions in Cape Town. The six different sites were sampled: two civic-led intervention sites, one expert-led rehabilitation site, two conservation sites and one abandoned site. These sites are compared in terms of their plant and insect diversity and then discussed in relation to their contingent management arrangements and in relation to conservation and abandoned land. Plant and insect diversity measured at the civic-led greening intervention sites suggest these sites are similar to adjacent conservation sites, while floristic composition differs. The inclusion of a vacant lot with poor species and growth form diversity shows the significant role of intervention in the ecological reformation of urban green space. By emphasizing the ecological outcomes, this study highlights the importance of civil society in linking conservation goals to more broad-based notions of quality of life and the 'good and just city'. Our results indicate that civic-led efforts warrant attention in keeping with those of experts, both in relation to meeting indigenous conservation targets, as well as supporting functional groups and wider ecological processes, with the acknowledged exception of fire. How to integrate such civic-led interventions into urban biodiversity management planning is still an open question.

Post-apartheid ecologies in the City of Cape Town : An examination of plant functional traits in relation to urban gradients

- In this study we explore species richness and traits across two urban gradients in the City of Cape Town. The first is the natural-urban boundary and the second is a socio-economic gradient informed by historical race-based apartheid planning. Plant species and cover were recorded in 156 plots sampled from conservation areas, private gardens, and public open green space. The socio-economic gradient transitioned from wealthier, predominantly white neighbourhoods to poorer, pre- dominantly black neighbourhoods. The socio-economic gradient was selected to fall within one original vegetation type to ensure a consistent biophysical template. There is a marked shift between the natural and urban plant communities in the City of Cape Town, with little structural affinity. Urban landscapes are dominated by grass, with low diversity compared to natural counterparts. A significant ecological gradient of reduced biodiversity, traits, and in turn functionality, was found across the socio-economic gradient. Wealthier communities benefit from more private green space, more public green space, and a greater plant diversity. Poorer communities have limited green space on all fronts, and lower plant and trait diversity. Plant communities with limited diversity are less resilient and if exposed to environmental perturbation would lose species, and associated ecosystem services faster than a species rich community. These species-poor plant communities mirror historical apartheid planning that is resistant to change. Based on how biodiversity, functionality, and associated ecosystem services and ecosystem stability are linked, the results of this study suggests how significant environmental injustice persists in the City of Cape Town.

Food and Green Space in Cities : A Resilience Lens on Gardens and Urban Environmental Movements

Tidskriftsartikel (refereegranskat)abstract
- This article examines the role played by urban gardens during historical collapses in urban food supply lines and identifies the social processes required to protect two crit- ical elements of urban food production during times of crisis - open green spaces and the collective memory of how to grow food. Advanced communication and transport technologies allow food sequestration from the farthest reaches of the planet, but have markedly increasing urban dependence on global food systems over the past 50 years. Simultaneously, such advances have eroded collective memory of food production, while suitable spaces for urban gardening have been lost. These factors combine to heighten the potential for food shortages when - as occurred in the 20th century - major economic, political or environmental crises sever supply lines to urban areas. This paper considers how to govern urban areas sustainably in order to ensure food security in times of crisis by: evincing the effectiveness of urban gardening during crises; showing how allotment gardens serve as conduits for transmitting collective social-ecological memories of food production; and, discussing roles and strategies of urban environmental movements for protecting urban green space. Urban gardening and urban social movements can build local ecological and social response capacity against major collapses in urban food supplies. Hence, they should be incorporated as central elements of sustainable urban development. Urban governance for resilience should be historically informed about major food crises and allow for redundant food production solutions as a response to uncertain futures.

- Las redes sociales entre actores y grupos de interés están recibiendo cada vez más atención en los estudios sobre la gestión de los recursos naturales, especialmente en los que se refieren a la gestión adaptativa basada en diferentes formas de participación y cogestión. Las redes sociales se han concebido principalmente como recursos que habilitan la colaboración y la coordinación entre diferentes actores. Aquí, continuamos la discusión iniciada por Newman y Dale (2005), que destacaron el hecho de que no todas las redes sociales son creadas iguales. Discutimos la relación entre algunas características estructurales y las funciones de las redes sociales con respecto al manejo de los recursos naturales, centrándonos en las implicaciones estructurales que a menudo se pasan por alto al estudiar las redes en el contexto del manejo de los recursos naturales. Presentamos varias medidas que se utilizan para cuantificar las características estructurales de las redes sociales y vincularlas con una serie de procesos como el aprendizaje, el liderazgo y la confianza, que se consideran importantes en el manejo de recursos naturales. Se muestra esquemáticamente que puede haber yuxtaposiciones entre las diferentes características estructurales que necesitan ser equilibradas en lo que nos imaginamos como estructuras de redes sociales conducentes a la cogestión adaptativa de los recursos naturales. Sostenemos que es esencial desarrollar una comprensión de los efectos que las diferentes características estructurales de las redes sociales tienen sobre la gestión de los recursos naturales.

Social networks in natural resource management : What is there to learn from a structural perspective?

Tidskriftsartikel (refereegranskat)abstract
- Social networks among actors and stakeholders are gaining attention in studies of natural resource management, particularly those of adaptive management based on different forms of participation and co-management. In this sense, social networks have primarily been envisioned as enabling different actors to collaborate and coordinate management efforts. Here, we continue the discussion initiated by Newman and Dale (2005), which highlighted the fact that not all social networks are created equal. We discuss the relation between some structural characteristics and functions of social networks with respect to natural resource management, thus focusing on structural implications that are often overlooked when studying social networks within the context of natural resource management. We present several network measures used to quantify structural characteristics of social networks and link them to a number of features such as learning, leadership, and trust, which are identified as important in natural resource management. We show schematically that there may be inherent juxtapositions among different structural characteristics that need to be balanced in what we envision as social network structures conducive to adaptive co-management of natural resources. We argue that it is essential to develop an understanding of the effects that different structural characteristics of social networks have on natural resource management.

- In this article we portray and unpack the fabric of urban expansion in contemporary Luanda. In doing so, we examine interdependencies and complementarities between the organization of oil extraction off the coast of Angola, the emergence of particular modalities of modernist city planning for the expansion of its capital city, and the proliferation of cement blocks in the making of new urban forms throughout its burgeoning peripheries. By showing how urban development has unfolded through the interconnected realization of multiple kinds of systematizing blocks—namely oil blocks, city blocks and cement blocks—we analyse key material components in the production of new markets and urban spaces in the Angolan capital. By tracing forms of capitalism and modularity in the making of contemporary Luanda, we develop the concept of blocos urbanism to draw attention to modes of standardization and the production of legibility in contemporary processes of urbanization. Through this study, we aim to contribute to the conceptual apparatus for deciphering our global urban condition.

Urban green commons : Insights on urban common property systems

Tidskriftsartikel (refereegranskat)abstract
- The aim of this paper is to shed new light on urban common property systems. We deal with urban commons in relation to urban green-space management, referring to them as urban green commons. Applying a property-rights analytic perspective, we synthesize information on urban green commons from three case-study regions in Sweden, Germany, and South Africa, and elaborate on their role for biodiversity conservation in urban settings, with a focus on business sites. Cases cover both formally established types of urban green commons and bottom-up emerged community-managed habitats. As our review demonstrates, the right to actively manage urban green space is a key characteristic of urban green commons whether ownership to land is in the private, public, the club realm domain, or constitutes a hybrid of these. We discuss the important linkages among urban common property systems, social–ecological learning, and management of ecosystem services and biodiversity. Several benefits can be associated with urban green commons, such as a reduction of costs for ecosystem management and as designs for reconnecting city-inhabitants to the biosphere. The emergence of urban green commons appears closely linked to dealing with societal crises and for reorganizing cities; hence, they play a key role in transforming cities toward more socially and ecologically benign environments. While a range of political questions circumscribe the feasibility of urban green commons, we discuss their usefulness in management of different types of urban habitats, their political justification and limitation, their potential for improved biodiversity conservation, and conditions for their emergence. We conclude by postulating some general policy advice.

- ABSTRACTAims To highlight the potential value of network analysis for conservation biogeography and to focus attention on some of the challenges that lie ahead in applying it to conservation problems.Location Global.Methods We briefly review existing literature and then focus on five important challenges for the further development of network-based approaches in the field.Results Our five challenges include (i) understanding cross-scale and cross-level linkages in ecological systems (top–down and bottom–up effects, such as trophic cascades, have been demonstrated in food webs but are poorly understood in nested hierarchies such as reserve networks and stream catchments), (ii) capturing dynamic aspects of ecological systems and networks (with a few exceptions we have little grasp of how important whole-network attributes change as the composition of nodes and links changes), (iii) integrating ecological aspects of network theory with metacommunity frameworks and multiple node functions and roles (can we link the spatial patterns of habitat patches in fragmented landscapes, the parallel networks of interacting species using those patches and community-level interactions as defined by metacommunity theory in a single framework?), (iv) integrating the analysis of social and ecological networks (particularly, can they be analysed as a single interacting system?) and (v) laying an empirical foundation for network analysis in conservation biogeography (this will require a larger data bank of well-studied networks from diverse habitats and systems).Main conclusions Recent research has identified a variety of approaches that we expect to contribute to progress in each of our five challenge areas. We anticipate that some of the most exciting outcomes of attempts to meet these challenges will be frameworks that unite areas of research, such as food web analysis and metacommunity theory, that have developed independently.

‘‘Right to the City’’ and the Structure of Civic Organizational Fields : Evidence from Cape Town
- 2018

Tidskriftsartikel (refereegranskat)abstract
- Abstract This article proposes a network analytic approach to the role of frames in shaping the structure of civic organizational fields. Adopting a perspective from the global South, it looks at the impact of the expression ‘‘Right to the city’’ (RTC) over alliance building among civil society actors, exploring patterns of collaborative ties among 129 civil society organizations active in Cape Town from 2012 to 2014. The article addresses two broad ques- tions: What is the relation between RTC and other frames that are also frequently invoked to describe urban struggles and issues? Does the RTC frame affect the structure of urban civic organizational fields in significant ways? Data suggest that while RTC plays a significant role in local civil society, it is neither the only interpretative frame that Capetonian civic organizations draw upon to characterize their activity, nor the more salient. ‘‘Urban conservation,’’ especially tied to nature conservation and environmental issues, actually shapes the structure of local organizational fields in a sharper manner. This is, however, a potentially more divisive frame, rooted as it is in the apartheid legacy that still shapes urban dynamics in the city.

- This study addresses social-ecological dynamics in the greater metropolitan area of Stockholm County, Sweden, with special focus on the National Urban Park (NUP). It is part of the Millennium Ecosystem Assessment (MA) and has the following specific objectives: (1) to provide scientific information on biodiversity patterns, ecosystem dynamics, and ecosystem services generated; (2) to map interplay between actors and institutions involved in management of ecosystem services; and (3) to identify strategies for strengthening social-ecological resilience. The green areas in Stockholm County deliver numerous ecosystem services, for example, air filtration, regulation of microclimate, noise reduction, surface water drainage, recreational and cultural values, nutrient retention, and pollination and seed dispersal. Recreation is among the most important services and NUP, for example, has more than 15 million visitors per year. More than 65 organizations representing 175,000 members are involved in management of ecosystem services. However, because of population increase and urban growth during the last three decades, the region displays a quite dramatic loss of green areas and biodiversity. An important future focus is how management may reduce increasing isolation of urban green areas and enhance connectivity. Comanagement should be considered where locally managed green space may function as buffer zones and for management of weak links that connect larger green areas; for example, there are three such areas around NUP identified. Preliminary results indicate that areas of informal management represent centers on which to base adaptive comanagement, with the potential to strengthen biodiversity management and resilience in the landscape.

Tidskriftsartikel (refereegranskat)abstract
- This paper addresses three interventions into urban green spaces—a wetland in Cape Town, a post- industrial site in New York, and a park outside London. Through their different contexts, they help to grasp a wider phenomenon: the protection of urban nature through the development of protective narratives. We analyze these interventions as examples of “value articulation”, which we view as a relational and sociomaterial practice that requires the enrolment of people, plants, and things that together perform, spread, and deploy stories about why given places need protection. For each case study, we also highlight the moments when narrative practices move beyond mere protection and start to change the very context in which they were developed. We refer to these as projective narratives, emphasizing how novel values and uses are projected onto these spaces, opening them up for reworking. Our analyses of these successful attempts to protect land demonstrate how values emerge as part of inclusive, yet specific, narratives that mobilize and broaden support and constituencies. By constructing spatial linkages, such narratives embed places in wider geographical ‘wholes’ and we observe how the physical landscape itself becomes an active narrative element. In contrast to rationalist and external frameworks for analyzing values in relation to urban natures (e.g., ecosystem services), our ‘bottom-up’ mode situates urban nature in specific contexts, helping us to profoundly rethink planning and practice in order to (i) challenge expert categories and city/nature dichotomies; (ii) provide vernacular ways of knowing/understanding; and (iii) rethink the role of urban designers.

Bringing Back the Political : Egalitarian Acting, Performative Theory

Bokkapitel (refereegranskat)abstract
- The political is categorically and fundamentally performative. Those that gain a voice as equals do not do so by demanding a right to speak within an already policed order, they stage equality and produce new spaces from where equality and freedom can be thought and acted out. This notion of the political, we argue, has to (again) become central in radical and critical theory, urban political ecology (UPE) and associated fields in the coming decade. This concluding essay draws on the chapters of the book to discuss what “politically performative theory” could mean and what challenges and possibilities it brings to a reconfigured UPE and in politicizing the environment.

Tidskriftsartikel (refereegranskat)abstract
- Urban political ecology (UPE) has provided critical insights into the sociomaterial construction of urban environments, their unequal distribution of resources, and contestation over power and resources. Most of this work is rooted in Marxist urban geographical theory, which provides a useful but limited analysis. Such works typically begin with a historical-materialist theory of power, then examine particular artifacts and infrastructure to provide a critique of society.We argue that there aremultipleways of expanding this framing, including through political ecology or wider currents of Marxism. Here, we demonstrate one possibility: starting from theory and empirics in the South, specifically, African urbanism. We show how African urbanism can inform UPE and the associated research methods, theory and practice to create a more situated UPE. We begin suggesting what a situated UPE might entail: starting with everyday practices, examining diffuse forms of power, and opening the scope for radical incrementalism.

Ecosystem services as technology of globalization : On articulating values in urban nature
- 2013
-
Ingår i: Ecological Economics. - : Elsevier BV. - 0921-8009 .- 1873-6106. ; 86, s. 274-284
-
Tidskriftsartikel (refereegranskat)abstract
- The paper demonstrates how ecosystem services can be viewed and studied as a social practice of value articulation. With this follows that when ecosystem services appear as objects of calculated value in decision-making they are already tainted by the social and cannot be viewed as merely reflecting an objective biophysical reality. Using urban case studies of place-based struggles in Stockholm and Cape Town, we demonstrate how values are relationally constructed through social practice. The same analysis is applied on ecosystem services. Of special interest is the TEEB Manual that uses a consultancy report on the economic evaluation of Cape Town's 'natural assets' to describe a step-by-step method to catalog, quantify and price certain aspects of urban nature. The Manual strives to turn the ecosystem services approach into a transportable method, capable of objectively measuring the values of urban nature everywhere, in all cities in the world. With its gesture of being universal and objective, the article suggests that the ecosystem services approach is a technology of globalization that de-historicizes and de-ecologizes debates on urbanized ecologies, effectively silencing other and often marginalized ways of knowing and valuing. The paper inscribes ecosystem services as social practice, as part of historical process, and as inherently political. A call is made for critical ethnographies of how ecosystem services and urban sustainability indicators are put into use to change local decision-making while manufacturing global expertise.

Histories of Heterogenous Infrastructures : Negotiating Colonial, Postcolonial and Oral Archives in Kampala, Uganda
- 2019
-
Konferensbidrag (refereegranskat)abstract
- Critical infrastructure studies are growing in importance to understand how sociocultural, ecological, and ecological relations are inscribed, negotiated, and contested in urban spaces. A major effort has been to ground such work in experiences of the global South, moving beyond the “modern infrastructure ideal” a fully networked city, towards conceptualizations of incremental, peopled, and heterogenous infrastructure. However, there are still few historical studies that depart from these new conceptualizations. In this paper we draw upon our empirical work in Kampala, Uganda, in an attempt to historicize “heterogenous infrastructure configurations” (Lawhon et al. 2017) through combining (and constructing) three distinct historical archives: (i) the colonial archives (based on traditional archival work in Kew National Archives in London); (ii) the official postcolonial archives (which meant to crisscross through Kampala to assemble documents, reports, photos and legal notes); and (iii) oral histories (where we interviewed elderly women and men with a long family history in the city). This work has led to several pertinent questions about “what to make of the colonial archives when they systematically exclude or distort the wider heterogenous infrastructure reality that surely existed in parallel to the ‘European’ city?” “why are postcolonial archives so difficult to find and assemble?” and “how to draw upon the richness and texture of oral histories from particular places, families and persons.” This paper then, reflects on how we have grappled with working across these archives with the aim to contribute more general ideas of how to situate and historicize the study of contemporary infrastructures in a postcolonial world (in communication with postcolonial historians as in Mamdani, Chakrabarty, Lalu, and Benson). By pushing different narratives to confront and clash, and by critically looking at our own practice, new histories arise. But also new questions; some which should have been asked long ago. We argue here for an approach of heterodoxa; one that opens for different meanings, archives and locations from where to construct histories and futures about infrastructure and urban spaces.

In Rhizomia : Actors, Networks and Resilience in Urban Landscapes

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- With accelerating urbanization it is crucial to understand how urban ecosystems play a part in generating ecosystem services for urban dwellers, such as clean water, spaces for recreation, stress relief and improved air quality. An equally important question relate to who gets to enjoy these benefits, i.e. the distribution of ecosystem services, and how issues of power and equity influence the management of ecosystems. Through case studies from the urban landscape of Stockholm, this doctoral thesis engages with these perspectives through combining ecological theory with social theory, including social network analysis, actor-network theory and social movement theory. Strategies for how to improve urban ecosystem management are presented along with frameworks for how to analyze issues of power and equity in relation to natural resource management.Paper I shows that ecosystem management can be studied through analyzing the structure of social networks, i.e. the patterns of relations between agencies, stake-holders and user groups. Paper II and Paper III analyze, based on a network survey of 62 civil society organizations and in-depth interviews, a transformational process of how an urban local movement managed to protect a large urban green area from exploitation (The Stockholm National Urban Park). Paper IV discusses, based on several case studies from Stockholm, a conducive network structure for linking managers and user groups (e.g. allotment gardens, cemetery managers, and urban planners) across spatial ecological scales so as to improve urban green area management. Paper V presents a framework to analyze the social-ecological dynamics behind the generation and distribution of ecosystem services in urban landscapes.The thesis points towards the notion of "a social production of ecosystem services" and argues for deeper engagement with urban political ecology and critical geography to inform governance and collective action in relation to urban ecosystems.

O Tempora! O Mores! Interrupting the Anthropo-obScene

Ingår i: Urban Political Ecology in the Anthropo-obscene. - Abingdon and New York : Routledge. - 9781138629196 ; , s. 25-47
-
Bokkapitel (refereegranskat)abstract
- We develop the term “the Anthropo-obScene” to show how various discourses on “the Anthropocene” have created a set of stages that disavow certain voices and render some forms of acting (human, non-human, and more-than-human) off-stage. Examples include consensual narratives of adaptive, resilient, and geo-engineered governance, but also more-than-human ontologies that, in spite their purported radicality, could lead to a problematic strengthening of technomanagerial discourse. With the Anthropo-obScene, we seek to interrupt the deepening of “immunological bio-politics” and a politicization of the socio-ecological conundrum we are in, while fully and radically embracing our interdependence with non-humans.

Bokkapitel (refereegranskat)abstract
- This chapter focuses on the book’s central theme on how to organize anew the articulation between emancipatory theory and political activism. Framed against the background of five major transformations that deal with planetary urbanisation to de-politicization, we argue that while UPE and associated fields have offered ways to analyse the politics of nature, they have less to offer in terms of what to do, in terms of thinking with radical political activists about new imaginaries and practices of emancipatory socio-ecological change. In light of this, we present the chapters as enriching the approaches to re-centre the political in thought and action in environmental and urban studies.

Konferensbidrag (refereegranskat)abstract
- This paper uses actor-network theory (ANT) to study a grassroots’ ecological rehabilitation project in a marginalized area of Cape Town. By tracing the stabilization of relations between residents, authorities, plants and green areas, the paper demonstrates how ANT can be enfolded into the study of African cities as an attentive way to rethink agency, empowerment and collective action. It also shows how ANT allows for the study of epistemological and ontological politics inherent to all collective action—here demonstrating how plants participated in giving voice to memories of oppression while undermining expert-based practices that separate Nature and Culture.

Scale-Crossing Brokers and Network Governance of Urban Ecosystem Services : The Case of Stockholm
- 2010

Ingår i: Ecology and Society. - : Resilience Alliance, Inc.. - 1708-3087. ; 15:4, s. 28-

Tidskriftsartikel (refereegranskat)abstract
- Urban ecosystem services are crucial for human well-being and the livability of cities. A central challenge for sustaining ecosystem services lies in addressing scale mismatches between ecological processes on one hand, and social processes of governance on the other. This article synthesizes a set of case studies from urban green areas in Stockholm, Sweden-allotment gardens, urban parks, cemeteries and protected areas-and discusses how governmental agencies and civil society groups engaged in urban green area management can be linked through social networks so as to better match spatial scales of ecosystem processes. The article develops a framework that combines ecological scales with social network structure, with the latter being taken as the patterns of interaction between actor groups. Based on this framework, the article (1) assesses current ecosystem governance, and (2) develops a theoretical understanding of how social network structure influences ecosystem governance and how certain actors can work as agents to promote beneficial network structures. The main results show that the mesoscale of what is conceptualized as city scale green networks (i.e., functionally interconnected local green areas) is not addressed by any actor in Stockholm, and that the management practices of civil society groups engaged in local ecosystem management play a crucial but neglected role in upholding ecosystem services. The article proposes an alternative network structure and discusses the role of midscale managers (for improving ecological functioning) and scale-crossing brokers (engaged in practices to connect actors across ecological scales). Dilemmas, strategies, and practices for establishing this governance system are discussed.

Social Movements and Ecosystem Services-the Role of Social Network Structure in Protecting and Managing Urban Green Areas in Stockholm
- 2008
-
Ingår i: Ecology and Society. - : Resilience Alliance, Inc.. - 1708-3087. ; 13:2
-
Tidskriftsartikel (refereegranskat)abstract
- Exploitation and degradation of urban green areas reduce their capacity to sustain ecosystem services. In protecting and managing these areas, research has increasingly focused on actors in civil society. Here, we analyzed an urban movement of 62 civil-society organizations-from user groups, such as boating clubs and allotment gardens, to culture and nature conservation groups-that have protected the Stockholm National Urban Park. We particularly focused on the social network structure of the movement, i.e., the patterns of interaction between movement organizations. The results reveal a core-periphery structure where core and semi-core organizations have deliberately built political connections to authorities, whereas the periphery gathers all user groups involved in day-to-day activities in the park. We show how the core-periphery structure has facilitated collective action to protect the park, but we also suggest that the same social network structure might simultaneously have constrained collaborative ecosystem management. In particular, user groups with valuable local ecological knowledge have not been included in collaborative arenas. Our case points out the inherent double-nature of all social networks as they facilitate some collective actions, yet constrain others. The paper argues for incorporating social network structure in theories and applications of adaptive governance and co-management.

The social production of ecosystem services : A framework for studying environmental justice and ecological complexity in urbanized landscapes
- 2013
-
Ingår i: Landscape and Urban Planning. - : Elsevier BV. - 0169-2046 .- 1872-6062. ; 109:1, s. 7-17

Tidskriftsartikel (refereegranskat)abstract
- A framework is constructed for how to relate ecosystem services to environmental justice. The benefits humans and society can derive from biophysical processes cannot be viewed as objectively existing “out there”, but as entangled in social and political processes. This is unpacked through the analytical moments of generation, distribution and articulation of ecosystem services. Social practice moderates the generation of benefits from biophysical processes (through urban development patterns and day-to-day management of urban ecosystems), but also who in society that benefits from them, i.e. the distribution of ecosystem services (viewed here as the temporal and spatial scales at which it is possible for humans to benefit from biophysical processes). Moreover, for biophysical processes to attain value in decision- making, a social practice of value articulation is needed. The framework then moves between two levels of analysis. At the city-wide level, an ecological network translates how urban ‘green’ areas, viewed as nodes, are interconnected by ecological flows (water, species movement, etc.) where nodes have different protective and management capacities. The network captures spatial complexity—what happens in one location, can have effects elsewhere. At the local level, urban struggles over land-use are studied to trace how actors utilize artifacts and social arenas to articulate how certain biophysical processes are of value. Competing networks of value articulation strive to influence land-use, and multiple local studies bring understanding of how power operates locally, informing city-wide analyses. Empirical studies from Stockholm, Cape Town and other cities inform the framework.

Towards situated histories of heterogenous infrastructures : Oral history as method and meaning
- 2022
-
Ingår i: Geoforum. - : Elsevier BV. - 0016-7185 .- 1872-9398. ; 134, s. 48-58
-
Tidskriftsartikel (refereegranskat)abstract
- Building on interviews with elderly people living in a low-income and auto-constructed settlement in Kampala, Uganda, this paper explores the notion of heterogenous infrastructure in its local spatial and temporal setting. Our aim is twofold. First, by intently listening to and weaving together situated narratives of how people over time have acquired infrastructural services, such as water, energy, waste, and sanitation, we reveal deeper insights of the socio-political, but also material structures and interactions at play between the State, the disenfranchised, and their intermediaries. Second, we start uncovering the so far largely unexplored potential of oral history as a method to meaningfully interpret the "infrastructural past" of postcolonial and Southern cities where most of ordinary people's experience was never put on record. Our findings point to the usefulness of oral history methods to widen the lens of who and what contributed to the production of fundamental resources for urban life-and its politics.

Transformative collective action : A network approach to transformative change in ecosystem-based management
- 2011
-
Ingår i: Social Networks and Natural Resource Management. - Cambridge : Cambridge University Press. - 9780521766296 - 9780511894985 ; , s. 255-287

Bokkapitel (refereegranskat)abstract
- [From Introduction] This chapter will strive to add to contributions made by other authors in describing and explaining transformative change. Special attention will be paid to elucidate the collective nature of these transformations, hence the title of transformative collective action. The analysis will show that in order to bring about radical institutional change of natural resource management, a whole network of individuals and organizations are needed that through time can sustain pressure for change. These actors furthermore need to relate to each other through information exchange and repeated collaborations in order to coordinate their collective action, to learn as they go along of what works and what does not work, and to negotiate their vision of change to reach some common ground that can unite their collective effort. This type of sustained collective action furthermore needs to operate through, and challenge, already established institutions, modes of thought and ways of doing things. As such we can talk about collective action as a ‘collective actor’ – the network of actors – that over time builds enough agency to generate institutional change.

Turning Livelihood to Rubbish? : The Politics of Value and Valuation in South Africa’s Urban Waste Sector
- 2021
-
Ingår i: African Cities and Collaborative Futures. - Manchester : Manchester University Press. ; , s. 97-120
-
Bokkapitel (refereegranskat)abstract
- We will discuss our experience of researching solid waste management politics in South African cities, in particular Cape Town, Johannesburg, and Ekurhuleni. The title of our project – Turning Livelihoods to Waste? – was designed to raise a serious of questions about ongoing trends in the waste sector and the implications. South African household waste management operates under a paradigm of cooperative governance where authority is distributed across various scales of government, business, and society. Recent efforts to expand, improve, and formalize solid household waste management and recycling initiatives have implications for those who currently work with waste - particularly for informal waste pickers or reclaimers, who do much of the primary work with waste in the global south. Despite promises of green economic development and job creation, many people working with waste in South Africa work are subjected to precarious and difficult work conditions or experience new uncertainties and vulnerabilities which threaten existing livelihood strategies. In turn, there are serious questions about whether waste workers should be expected to work in dangerous conditions, and what sorts of alternate arrangements may be more just and more ecologically sustainable.

Urban Plants and Colonial Durabilities
- 2020
-
Ingår i: The Botanical City. - Berlin : jovis Verlag GmbH. ; , s. 71-81
-
Bokkapitel (refereegranskat)abstract
- The long legacy of colonization that is rooted in how plants are known is mostly out of sight. But at times the colonial legacy of botany becomes all too apparent. This article draws upon ethnograhic field work in Cape Town, South Africa, over several years to contribute knoweldge how colonial and imperial forms of science and colonial management influenced urban botany and later urban ecology. But it points towards a more general argument that is often forgotten when the history of urban ecology and “urban nature knowledge” is written up. This works to decenter or on-stage what has often been silenced in the now taken-for-granted "success" story of the growth of modern urban ecology. What are the colonial remains within urban ecology and urban environmental knowledge today?

Urban Transitions : On Urban Resilience and Human-Dominated Ecosystems
- 2010
-
Ingår i: Ambio. - : Springer Science and Business Media LLC. - 0044-7447 .- 1654-7209. ; 39:8, s. 531-545
-
Tidskriftsartikel (refereegranskat)abstract
- Urbanization is a global multidimensional process paired with increasing uncertainty due to climate change, migration of people, and changes in the capacity to sustain ecosystem services. This article lays a foundation for discussing transitions in urban governance, which enable cities to navigate change, build capacity to withstand shocks, and use experimentation and innovation in face of uncertainty. Using the three concrete case cities-New Orleans, Cape Town, and Phoenix-the article analyzes thresholds and cross-scale interactions, and expands the scale at which urban resilience has been discussed by integrating the idea from geography that cities form part of "system of cities" (i.e., they cannot be seen as single entities). Based on this, the article argues that urban governance need to harness social networks of urban innovation to sustain ecosystem services, while nurturing discourses that situate the city as part of regional ecosystems. The article broadens the discussion on urban resilience while challenging resilience theory when addressing human-dominated ecosystems. Practical examples of harnessing urban innovation are presented, paired with an agenda for research and policy.
