Post-Fordist transformation,the sustainability concept and social relations with nature: a case study of the Hamburg region

Following the United Nations Conference on Environment and Development, the concept of sustainability in general and of urban sustainability in particular has become increasingly significant in the course of the 1990s. Even if the environmental problems of cities are far from being solved, one can interpret this development as a change in the relationship between society and nature on both a discursive and a material level. At the same time the transition from Fordism to post-Fordism has given rise to new forms of urban entrepreneurialism, with an absolute priority to economic competitiveness on the one hand and sharpened social conflicts on the other. Looking at the case of the Hamburg region, the article discusses the interaction of these processes. Contrary to the understanding of sustainability as a broadly accepted policy goal it conceptualizes sustainability as a terrain of conflict. As such, we will argue, the sustainability concept and the underlying change in social relations with nature contribute to containing the contradictions of capitalist societalization, which in the transition to post-Fordism have become more visible again.

Can home gardens scale up into movements for social change? The role of home gardens in providing food security and community change in San Jose,California

Urban policymakers and sustainable food activists have identified urban agriculture as an important strategy for confronting a host of urban problems, including food insecurity, health disparities, access to urban green space and community economic revitalisation. Much recent work on urban agriculture has examined community and school gardens, but little research has been undertaken on home gardens as a solution to urban problems. This article examines a home-gardening programme in San Jose, California, La Mesa Verde, asking whether some of the benefits found in community gardens can be found in home gardens. Specifically, we look at financial, health and community benefits, examining the potential of home gardens to become forces for broader social change. We ask whether gardens can become agents of cultural preservation, self-determination, particularly for recent immigrants who use these spaces to build identities and work towards collective action and self-determination.     

Reluctant pioneers in the European periphery? Environmental activism,food consumption and “growing your own”

East European food self-provisioning (FSP) has fascinated scholars of post-socialism ever since the early 1990s. In keeping with its predominantly economic and cultural conceptualisations, much of this research has been concerned with FSP’s role in household economy and with the social profile of its practitioners. In contrast to western conceptualisations of FSP as an opportunity to expand food activism and foster social justice and environmental sustainability, post-socialist FSP has rarely been considered as such. In Czechia, FSP is practised by 43% of citizens and many of them do so in a relatively environmentally friendly way. Yet, most food-related campaigns run by environmental NGOs (ENGOs) pay little attention to FSP and focus on market-based ethical consumerism and alternative food networks instead. Using insights from actor-network theory, this paper discusses how Czech ENGO activists engage with FSP through discourse and in practice. Based on ethnographic fieldwork and interviews with leading activists, we show that FSP does figure in non-food-related campaigns and that the FSP practised by activists themselves or the FSP carried out by relatives and relatives’ friends are not the same as the FSP on which they are reluctant to campaign. These differences, which include controllability and the time-consuming nature of practising FSP according to some of the activists’ ideals, help this paper to come to an initial understanding of why Czech ENGOs do not run campaigns explicitly focused on FSP at the moment and shed some light on how this could change in the future.     

Facilitating (?) urban agriculture in Philadelphia: sustainability narratives in the inequitable city

In 2008, the city of Philadelphia made increasing healthy food access a priority for sustainable development. Recognising that almost 25% of the population are considered food insecure, government agencies, non-governmental organisations and community leaders sought to increase food access through increasing food production and access to land in the city. Urban agriculture has gradually been incorporated in sustainability narratives in the past decade, both providing a platform for advocates to inform on policymaking, and potentially stripping away the political and activist origins of gaining access to food, land and green spaces in the city. In this paper, we argue that the depoliticising of urban agriculture advocacy through its incorporation in sustainability planning may serve to increase existing inequities in the city. Focusing on the policy-making scale, we examine measures enacted under the Philadelphia Greenworks Sustainability Plan to facilitate urban agriculture in the city. Our preliminary findings suggest that the processes by which urban agriculture gains acceptance demonstrate a disconnect in urban agriculture advocacy and policymaking and further work is needed to understand the impacts of the formalising of urban agriculture in Philadelphia.     

Towards urban food sovereignty: the trials and tribulations of community-based aquaponics enterprises in Milwaukee and Melbourne

Community-based urban aquaponics enterprises represent a new model for how to blend local agency with scientific innovation to deliver food sovereignty (FS) in cities, re-engaging and giving urban communities more control over their food production and distribution. Little is known, however, about the factors and outcomes that determine the success or failure of these enterprises. This paper explores stakeholder experiences of building community-based urban aquaponics enterprises to understand the internal and external factors that impact on their success or failure. We draw upon existing FS, social enterprise and aquaponics literature, to identify factors in the related area of community-based urban agriculture. For exploring these factors, we use a comparative case study methodology for two cases in Milwaukee and Melbourne, conducting in-depth interviews with key stakeholders, exploring their relative contexts, objectives and structure. Based on these findings, we highlight the challenges and suggest relevant indicators for establishing an urban aquaponics enterprise.     

Ethics,Narrative, and Agriculture: Transforming Agricultural Practice through Ecological Imagination

The environmental degradation caused by industrial agriculture, as well as the resulting social and health consequences, creates an urgency to rethink food production by expanding the moral imagination to include agricultural practices. Agricultural practices presume human use of the earth and acknowledge human dependence on the biotic community, and these relations mean that agriculture presents a separate set of considerations in the broader field of environmental ethics. Many scholars and activists have argued persuasively that we need new stories to rethink agricultural practice, however, the link—the story that does and can shape agricultural practice—has not yet been fully articulated in environmental discourse. My analysis explores how language has shaped existing agricultural models and, more important, the potential of story to influence agricultural practice. To do this, I draw upon cognitive theory to illustrate how metaphoric and narrative language structures thought and influences practice, beginning with my contention that industrial agriculture relies on a discourse of mechanistic relations between humans and a passive earth, language that has naturalized the chemically intensive monocultures prevalent in much of the American Midwest. However, alternative agricultures, including organic agriculture, agro-ecology, and ecological agriculture, emphasize qualities such as interdependence and reciprocity and do so as a deliberate response to the perceived inadequacies of industrial agriculture and its governing narrative. Exploring the different discourses of agricultural systems can help us think through different modalities for human relations with the biotic community and demonstrate story’s potential role in altering practice.     

The multifunctionality of urban farming: perceived benefits for neighbourhood improvement

Urban farming – a type of urban agriculture focused on entrepreneurial food production – serves multiple functions in neighbourhoods; yet these are not well delineated. Expectations for urban farming often centre on traditional measures of economic development, potentially overlooking other benefits. Through a qualitative case study conducted in Baltimore, Maryland, we sought to understand community perceptions regarding the ways in which urban farms can benefit cities. Interviews with residents, neighbourhood leaders, and urban farmers in three residential neighbourhoods with urban farms revealed the pathways by which community members view farms as improving neighbourhoods. Benefits stemmed from four primary changes urban farms made to study neighbourhoods: creation of public projects welcoming involvement, physical improvement of degraded space, production of local food, and creation of new businesses. These changes led to multiple perceived benefits including increased social connectedness, a transformed physical landscape, improved neighbourhood reputation, increased access to fresh produce, and educational, youth development, and employment opportunities. Our findings demonstrate the importance of a multifunctional paradigm that accounts for social and educational functions in assessing the value of urban farming and bring empirical evidence to the concept of multifunctional agriculture. Urban farms with strong social aims may appear to contribute little to economic development if measured using traditional indicators of success such as job creation or fiscal impacts, but provide numerous other benefits for community development.     

Food production in the city: (re)negotiating land,food and property

This paper addresses issues of access to land for food production in Toronto by offering fresh perspectives on urban agriculture in the neo-liberal city of the global north. It examines attempts to scale up urban agriculture that emphasise changing the relationships between land access, property and new collaborative relationships among different stakeholders. These initiatives involve renegotiating access to land for growing food between private property owners and landless growers, concomitant shifts in control over valued resources and commercialisation. These shifts are often based on relations of trust within a sharing economy rather than public battles over political decisions to develop urban agriculture lands. Growing food on private lands in the city is political in challenging taken-for-granted ideas and practices of property and urban agriculture. New approaches offer options for training and income, as well as expanding the land base for urban agriculture. Small-scale farming projects are affirmative political manoeuvres. They challenge urban residents to consider land for food production across the categories of public and private property. We document three approaches that challenge current property relations: temporary use of a development site through “soft” squatting; redesignating suburban backyards for farmer training and community-based and private food production; and garden sharing of private home backyards for urban food production and commercial growing. Such initiatives articulate alternative visions of sustainability and food security that rely on principles of collaboration and a sharing economy that challenge prevailing notions of property ownership and food security.

Screening for Selected Human Pharmaceuticals and Cocaine in the Urban Streams of Manaus,Amazonas, Brazil

Pharmaceuticals and illicit drugs are contaminants that are generally ubiquitous in wastewater treatment plant effluents with their release into the environment being well understood in North America, Europe, and Asia. There is, however, less information on the release of human pharmaceuticals and illicit drugs from regions undergoing rapid land use, economical, and social changes, such as Brazil. This encompasses many areas in the tropical zone where releases of emerging contaminants may impact pristine, bio‐diversity rich ecosystems. In this study, the occurrence of human pharmaceuticals and the illicit drug cocaine was determined in the Rio Negro and two of its tributaries that receive large amounts of untreated sewage, the Igarapé Mindu and the Igarapé do 40, passing through the city of Manaus, Brazil. In addition to cocaine and its metabolite, benzoylecognine, propranolol, diclofenac, amitriptyline, carbamazepine, carbamazepine‐epoxide, citalopram, metoprolol, carisoprolol, and sertraline were all detected in two urban tributaries at low ng/l concentrations similar to those typically found in urban surface waters. Concentrations in the Rio Negro were typically lower than detection limits due to the large level of dilution, although traces of a range of pharmaceuticals were detected in the Rio Negro in proximity of the confluence of the urban streams. The data represent new information on the emissions of pharmaceuticals from a newly industrialized region of Brazil.     

Cultural landscapes and environmental ethics: The case of puslinch township's historic roadside trees

Conclusion I have argued, then, that is simplistic and potentially dangerous to suppose that a contractarian model can adequately account for all of the moral relations in agriculture or serve singularly as a basis for policy. Conversely, I do not naively argue that we ought simply to replace a contractarian based agricultural ethic with an ethic of care such as the one I have outlined. A single farmer may be a spouse, parent, son or daughter, caretaker of land, keep of animals, business operator and partner, employer, processor, and consumer. Agriculture itself encompasses all of these relations. Both our ethical systems and social and economic policies must reflect and build on this diversity of contexts and associated practices.     

Urban Environmental Management in Shanghai: Achievements, Problems, and Prospects

This article critically reviews the evolution of urban environmental management in Shanghai since 1978. Established in a transitional postsocialist economy and shaped by a spectacular urban redevelopment process, the current environmental management framework of Shanghai has succeeded in mitigating major industrial pollution and improving urban amenities with unprecedented pace and magnitude. However, it generally failed to take social equity and environmental justice issues into consideration. Based on Haughton’s models of sustainable urban development, this article proposes four priorities and five principles within the framework of a fair shares cities model for the future environmental management of Shanghai and briefly discusses their policy implications and implementation issues. The authors argue that Haughton’s approach is relevant to Shanghai’s case because the essence of his argument—the multidimensional equity principles—is the core of the concept of sustainable development.     

Food access,food security and community gardens in Rockford,IL

Urban agriculture projects seek to ameliorate issues of food access and food security for people living in areas with low access to fresh foods, including food deserts. Within this discourse, community gardens have been promoted as vehicles to reclaim unused urban space, produce food locally and connect populations to their food sources and larger community. A variety of community garden models exist; in the Midwestern city of Rockford, Illinois, many community gardens grow food for donation to food pantries as part of a programme to benefit socioeconomically disadvantaged persons in the city. However, the ability of these gardens to involve neighbourhood participants and provide the social capital-related benefits attributed to community gardens in the literature is uncertain. Here we examine community gardens in Rockford, IL to assess the extent to which they contribute to residents’ ability to obtain fresh produce as well as other social benefits. Data for this project come from a combination of interviews with gardeners, focus groups with food pantry users and a survey of pantry users. We find that while non-gardening community members are benefitting from the increased produce that the gardens provide, they are not receiving all of the social and communal benefits associated with actively participating in a garden.     

Gathering “wild” food in the city: rethinking the role of foraging in urban ecosystem planning and management

Recent “green” planning initiatives envision food production, including urban agriculture and livestock production, as desirable elements of sustainable cities. We use an integrated urban political ecology and human–plant geographies framework to explore how foraging for “wild” foods in cities, a subversive practice that challenges prevailing views about the roles of humans in urban green spaces, has potential to also support sustainability goals. Drawing on research from Baltimore, New York City, Philadelphia, and Seattle, we show that foraging is a vibrant and ongoing practice among diverse urban residents in the USA. At the same time, as reflected in regulations, planning practices, and attitudes of conservation practitioners, it is conceptualised as out of place in urban landscapes and an activity to be discouraged. We discuss how paying attention to urban foraging spaces and practices can strengthen green space planning and summarise opportunities for and challenges associated with including foragers and their concerns.     

From “What is” to “What Should Become” Conservation Biology? Reflections on the Discipline’s Ethical Fundaments

In this essay, I build on the article by Soulé that established the foundation for the field of conservation biology. I analyze the presuppositions that have guided the discipline’s ethics in the 30 years since that article first appeared. I argue that conservation biology’s normative postulates introduced a paradigm shift that placed the diversity of the biota instead of the biota itself at the center of its ethics. I show that the ensuing priorities in the valuation of nature entail several contradictions at the ethical level and are justifiable only through scientific postulates. Identifying potential revisions and latent ideological issues in science, I defend the position that such scientific legitimization of conservation measures becomes disputable when this option undermines the ethical status of non-human life. Furthermore, I explain the absence of social feedback regarding conservation measures from the perspective of this shift. I conclude with an invitation to critically rethink the ethical basis of conservation sciences so that these fields may achieve their intention of playing a key role in halting the destruction of nature and in encouraging society’s support.     

Urban agriculture,civil interfaces and moving beyond difference: the experiences of plot holders in Dublin and Belfast

Recent literature suggests that a “shared politics of place” attained through joint activities fosters social integration and provides people with a means to practise co-operation [Baumann, G., 1996. Contesting culture: discourses of identity in multi-ethnic London. Cambridge: Cambridge University Press; Sanjek, R., 1998. The future of us all: race & neighbourhood policies in New York City. Ithaca, NY: Cornell University Press; Sennett, R., 2012. Together: the rituals, pleasures and politics of cooperation. UK: Penguin]. Such a “shared politics of place” is most likely to occur in the context of public space conceptualised broadly as “the setting for everyday spatial behaviour of individuals and communities, emphasizing ordinary activities of citizens” [Lownsbrough, H. and Beunderman, J., 2007. Equally spaced? Public space and interaction between diverse communities. London: Demos, p. 8]. Here we explore one element of such public space – urban agriculture sites – with a view to identifying the extent to which a “shared politics of place” can be created and nurtured among the cultivating citizenry. The paper draws on data collected on allotment gardening sites in two urban contexts: Dublin (Ireland) and Belfast (Northern Ireland) over the period 2009–2013. We demonstrate the centrality of allotment cultivation to the generation of solidarity, mutuality and trust among participating citizens. Individuals engaging in allotment gardening in both Dublin and Belfast create and sustain civil interfaces – dismantling barriers, exchanging knowledge, challenging stereotypes, generating empathy and getting on with the business of simply getting on with their lives. The modus operandi of allotment gardening is predicated on a willingness to disregard social and ethno-national categorisations while on site. This is not to deny that such differences exist and persist, but allotments offer a “space of potential” where those differences are, at least for a time, rendered less salient.     

Industrial Farming is Not Cruel to Animals

Critics of industrial animal agriculture (also known as “factory” farming) have argued that its practices are cruel, inhumane, or otherwise degrading to animals. These arguments sometimes form the basis of a larger case for the complete abolition of animal agriculture, while others argue for more modest welfare-based reforms that allow for certain types of industrial farming. This paper defends industrial farming against the charge of cruelty. As upsetting as certain practices may seem, I argue that they need not be construed as cruel or inhumane. Any link between industrial farming and cruelty or inhumanity is contingent on certain cultural, behavioral, and psychological facts that are person-dependent. For many people working in animal agriculture, these facts do not obtain. To be sure, industrial animal agriculture has real moral hazards that must be carefully avoided, but all that this shows is that working with animals is not for everyone.     

“The Lucky country”? A critical exploration of community gardens and city–community relations in Australian cities

Urban agriculture (UA) has the potential to expand beyond the grassroots level to meet the social, cultural, economic and food needs of urban dwellers. At its core, UA represents an alternative use of urban space that occurs with or without government support or approval. The experiences of community gardeners and their views of, and engagement in, community gardens as a form of UA, or local “alternative food networks”, is a focal point of this paper. Relying on Australian city case studies, this paper explores community gardens, using critical urban approaches concerning “rights to the city” and diverse economies. Findings from this study reveal how community gardeners understand and participate in diverse economies and extended local food networks. They also identify respondents’ views of local councils as barriers to the emergence of community gardens, and other forms of UA, as a local response to growing concerns over impacts of the global food chain on food security. In contrast to other Western cities, effective city–community relations for community garden growth have yet to emerge in Australian cities, as key policy areas for urban sustainability and social cohesion.     

WATER QUALITY IN AGRICULTURAL,URBAN, AND MIXED LAND USE WATERSHEDS1

ABSTRACT: Water quality and nonpoint source (NPS) pollution are important issues in many areas of the world, including the Inner Bluegrass Region of Kentucky where urban development is changing formerly rural watersheds into urban and mixed use watersheds. In watersheds where land use is mixed, the relative contributions of NPS pollution from rural and urban land uses can be difficult to separate. To better understand NPS pollution sources in mixed use watersheds, surface water samples were taken at three sites that varied in land use to examine the effect of land use on water quality. Within the group of three watersheds, one was predominately agriculture (Agricultural), one was predominately urban (Urban), and a third had relatively equal representation of both types of land uses (Mixed). Nitrogen (N), phosphorus (P), total suspended solids (TSS), turbidity, pH, temperature, and streamflow were measured for one year. Comparisons are made among watersheds for concentration and fluxes of water quality parameters. Nitrate and orthophosphate concentrations were found to be significantly higher in the Agricultural watershed. Total suspended solids, turbidity, temperature, and pH, were found to be generally higher in the Urban and Mixed watersheds. No differences were found for streamflow (per unit area), total phosphorus, and ammonium concentrations among watersheds. Fluxes of orthophosphate were greater in the Agricultural watershed that in the Urban watershed while fluxes of TSS were greater in the Mixed watershed when compared to the Agricultural watershed. Fluxes of nitrate, ammonium, and total phosphorus did not vary among watersheds. It is apparent from the data that Agricultural land uses are generally a greater source of nutrients than the Urban land uses while Urban land uses are generally a greater source of suspended sediment.     

Of parks and politics: the production of socio-nature in a Gujarati town

Urban parks in India are often discussed as positive environmental projects, and their creation appears as unproblematic in public discourse. This paper presents the creation of a municipal park in a small city in Gujarat, India. Using insights from history and architecture, we stress the importance of reading parks as political and to some extent ideological projects in the larger context of city-making. The political ecology and history of the particular park studied here allow us to problematise the socio-ecological project of urban “beautification” via park creation. The municipal park, established in the centre of a small urban agglomeration after displacing a slum settlement from the site, is – as we argue – an integral part of a local geography of power. As such it expresses several registers of values upheld by local elites and brings into focus highly conflictive social relations. The case study contributes to further developing a situated urban political ecological approach that starts theorising cities from the South. It moreover offers a critical perspective on the understudied urban nature of small towns.
