Where is urban food policy in Switzerland? A frame analysis

Food is increasingly included on the urban agenda in many countries, and comprehensive food policies have been developed in several cities, but the development of articulate urban food policies is still in its infancy in Switzerland. The goal of this paper is to explore the ways in which food is framed in official policies in Switzerland and thereby gain a better understanding of the potential for the development of urban food policies. The analysis is based on a case study approach focusing on the formal frames of food: reconstructed from official policy documents on agriculture, food, health, environment, and planning, at the federal and the local level. The results show that ‘urban food’ is not a major topic in most policy documents and that the dominant frame of food is economic. There is a clear distinction between the rural and the urban, and there were no frames integrating (rural) food production and (urban) consumption, across the city’s departments, or between the local and the federal level. We can conclude that there is not yet a comprehensive urban food policy in Switzerland. The analysis further allows the nomination of two possible pathways to guide the development of coherent and integrative urban food policies.     

Are more restrictive food cadmium standards justifiable health safety measures or opportunistic barriers to trade? An answer from economics and public health

In the past, Cd regulations have imposed trade restrictions on foodstuffs from some developing countries seeking to access markets in the developed world and in recent years, there has been a trend towards imposing more rigorous standards. This trend seems to respond more to public and private sectors strategies in some developed countries to create disguised barriers to trade and to improve market competitiveness for their industries, than to scientifically justified health precautions (sanitary and phytosanitary measures) and/or technical barriers to trade acceptable under the Uruguay Round Agreement of the WTO. Applying more rigorous Cd standards in some developed countries will not only increase production costs in developing countries but it will also have a large impact on their economies highly dependent on international agricultural markets. In the current literature there are large uncertainties in the cause-effect relationship between current levels of Cd intakes and eventual health effects in human beings; even the risk of Cd to kidney function is under considerable debate. Recent works on the importance of zinc:Cd ratio rather than Cd levels alone to determine Cd risk factors, on the one hand, and on the declining trends of Cd level in foods and soils, on the other, also indicate a lack of scientific evidence justifying more restrictive cadmium standards. This shows that developing countries should fight for changing and making more transparent the current international structures and procedures for setting sanitary and phytosanitary measures and technical barriers to trade.     

Developing quality in agro‐food supply chains: A Welsh perspective

This paper describes the challenges facing the agro‐food sector in Wales as it searches for a more sustainable future than that provided by the productivist post‐war food regime. Growing concerns for food quality, coupled with the potential for wider regional spin‐offs from quality foods have highlighted the opportunities for Wales to exploit environmental quality in its food production. At present, however, Wales has a complex array of supply chains with a varying emphasis on quality. This paper compares and contrasts two models of supply chain development in Wales—mainstream meat commodity production and organic foods—for purposes of focusing questions on the development of quality agro‐food production. The paper concludes by identifying critical opportunities for and constraints upon the wider embodiment of quality in regional food supply chains.     

A capabilities approach to arts and culture? Theorizing community development in West Philadelphia

Arts and culture are increasingly part of the planning and development toolkit in the USA. Justifications for investment in the arts often center on economic development outcomes. In contrast, we propose the use of Amartya Sen’s capabilities approach to human development, which asserts the importance of the freedom to achieve personal and group well-being through the creation of conditions that maximize opportunity. This paper advances the capabilities approach by exploring arts and culture engagement in three adjacent West Philadelphia neighborhoods. Amid conditions of material deprivation and pressure from gentrification, neighborhood residents strongly articulate their belief in arts and culture as a strategy of community empowerment. The capabilities approach offers planners an opportunity to reevaluate the way they incorporate arts and culture in their efforts. We conclude that arts-based development should employ comprehensive place-based strategies, with social and spatial justice as guides to practice and primary metrics for success.     

Stakeholder Representations of Gentrification in Amsterdam and Berlin: A Marginal Process?

In recent years, several studies have highlighted how gentrification strategies are imposed under the discursive umbrella of ‘social mixing’. However, most evidence is based on Anglo-Saxon experiences. This paper sets out to expand the geography of gentrification by looking at the representation of processes and policies of gentrification as put forward by key stakeholders in Nord-Neukölln (Berlin) and Indische Buurt (Amsterdam). It shows that in both contexts, stakeholders and policy documents engage with the concept of gentrification, rather than avoid it. Due to public-policy influence and local criticisms, this engagement differs between both cases. In Nord-Neukölln, the term is heavily contested and policy-makers attempt to refute accusations of gentrification, while in the Indische Buurt, the process is explicitly pursued as a positive policy instrument by policy-makers. Different representations within each case are shown to be influenced by the characteristics of in-moving and out-moving residents; the employed timeframe and the perceived influence of institutions on urban regeneration.     

Safety first? Production pressures and the implications on safety and health

The prominence of production, schedule, cost and economic wellbeing in government policy and review is explored and contrasted with the status of safety. The connection between productivity as an objective and safety as a constraint is reviewed, though it can be concluded that in spite of widespread belief of a connection there is very little empirical causal evidence for high production pressure causing negative effects on safety. Nevertheless, the inverse is mooted, that high levels of safety has had a negative impact on productivity in construction. This possibility is discussed in the context of government rhetoric which tends to be highly critical of construction’s economic shortcomings yet quite silent on the matter of its safety successes. The essay concludes with a possible vision for the future that allows safety and productivity to be re-positioned in terms of their potential symbiosis.     

Housing assets to the elderly in urban China: to fund or to hedge?

Housing has become the most important asset held by a large proportion of China’s older citizens. Therefore, the role of housing wealth in the consumption decisions of the elderly is a central topic of research and gains insights into the saving, investment and consumption decisions made throughout household life to meet later pension needs. In this paper, using data drawn from a household survey conducted between 2002 and 2009, we estimate the influence of housing wealth on the non-housing consumption of the elderly, and identify the mechanisms underlying this relationship. We find that on average, changes in housing wealth have limited effects on elderly consumption. However, we also find that the role of housing in consumption differs according to the income, health status, and living arrangements of the elderly. The paper draws attention to the influence of housing and its links with social and health-care systems on the lives of older people, with important policy implications.     

Sustainability Science and Planning: A Crucial Collaboration?

In this age of public skepticism about science, sustainability science offers a way to increase the application of science in planning and policy. This paper explores the relationship between science and society and the emergence of sustainability science. A comparison of the theory and practice of sustainability science and planning reveals the potential for a natural partnership. Based on the analysis, I suggest ways that planning may bridge the gap and build on the opportunity to strengthen its purpose and impact.     

Contestation and conservatism in neighbourhood planning in England: reconciling agonism and collaboration?

Neighbourhood planning was formally enabled as a statutory part of the English planning system under the Localism Act 2011. This element of formal planning has generated significant interest as it actively requires local communities to lead on producing a Neighbourhood Development Plan (NDP) and is widely recognised as formalising co-produced planning. The paper reflects on research undertaken with a sample of neighbourhoods active in producing a neighbourhood plan, and develops a critical discussion about the experience of those participants. The findings highlight that existing power relations, national priorities, the framing of neighbourhood planning regulations, local political tensions and local resource constraints affect the emerging practices of neighbourhood planners in England. Many groups have adopted conservative positions or are finding their NDPs are being limited by consultants, local authorities or examiners, often concerned with how the NDPs will fare in the contested environment of planning and development in neo-liberal times. While some have contended that neighbourhood planning can form part of a progressive localism and there is some hope for such participatory spaces, our view is that innovation is being constrained if not entirely suppressed. We conclude that reform to neighbourhood planning is needed if it is to realise the ambitions of inclusive, empowered and responsible planning at the very local scale.     

Cleaning practices and cleaning products in nurseries and schools: to what extent can they impact indoor air quality?

In the framework of a nationwide survey on indoor air quality conducted from September 2009 to June 2011 in 310 nurseries, kindergartens, and elementary schools in all regions of France, cleaning practices and products were described through an extensive questionnaire completed on‐site by expert building inspectors. The questionnaire included the cleaning frequencies and periods, cleaning techniques, whether windows were open during cleaning, and the commercial names of the products used. Analysis of the questionnaire responses showed that cleaning was generally performed daily for furniture and floors. It was performed mostly in the evening with wet mopping and with one or more windows open. Five hundred eighty‐four different cleaning products were listed, among which 218 safety data sheets (SDSs) were available and analyzed. One hundred fifty‐two chemical substances were identified in the SDSs. The typical substances in cleaning products included alcohols, chlorides, terpenes, aldehydes, and ethers; more than half of them are irritants. Two endocrine disruptors, 2‐phenylphenol and Galaxolide, were identified in two cleaning products used every day to clean the floors, in seven kindergartens and in a nursery respectively. Eleven reactive substances containing C=C double bonds, mostly terpenes, were identified in a wide variety of cleaning products.     

Where angels fear to tread? Mapping women and men in India

"The authors have produced the ?Atlas of Women and Men in India', using material from the 1991 Census, mainly at district level. The Atlas may be unacceptable to Indian geographers because it seeks to question the authority of numerical data and of maps, and to Western geographers because this is ?mapping before we understand the process'. The authors introduce maps of the sex ratio in India and explore through a map of changes in the sex ratio 1981-91 some numerical, analytical, and ethical problems of such mapping. The Indian feminist activists consulted want the Atlas for advocacy: does this justify its production?"     

Dichlobenil and 2,6-dichlorobenzamide (BAM) in the environment: what are the risks to humans and biota?

Dichlobenil is a herbicide widely used for weed control, mainly in non-agricultural areas and in the aquatic environment. When released into the environment, dichlobenil can undergo many processes such as vaporization to air, binding to soil and sediment, as well as degradation to a number of new compounds. The main metabolite is 2,6-dichlorobenzamide (BAM) which is water soluble and causes ground water contamination. It is frequently found in levels exceeding maximum allowed concentrations of pesticides and metabolites in ground water (0.1 μg/L) set by the European Commission. The environmental distribution of both dichlobenil and BAM was outlined and the risk quotients were calculated for biota and for humans. For organisms living in aquatic habitats, risk quotients were low for both dichlobenil and BAM, approximately 0.02 for dichlobenil and 2.4 · 10^− 4 to 1.3 · 10^− 3 for BAM. For humans, a margin of safety above 15,000 was estimated for dichlobenil. The most unusual and extreme concentration of BAM ever found in ground water is 560 μg/L. Even at this concentration, the margin of safety for humans was 313 for a 70 kilo man and 56 for a 25 kilo child. The results clearly demonstrate that the risks to biota and humans are very low.     

LES over RANS in building simulation for outdoor and indoor applications: A foregone conclusion?

Large Eddy Simulation (LES) undeniably has the potential to provide more accurate and more reliable results than simulations based on the Reynolds-averaged Navier-Stokes (RANS) approach. However, LES entails a higher simulation complexity and a much higher computational cost. In spite of some claims made in the past decades that LES would render RANS obsolete, RANS remains widely used in both research and engineering practice. This paper attempts to answer the questions why this is the case and whether this is justified, from the viewpoint of building simulation, both for outdoor and indoor applications. First, the governing equations and a brief overview of the history of LES and RANS are presented. Next, relevant highlights from some previous position papers on LES versus RANS are provided. Given their importance, the availability or unavailability of best practice guidelines is outlined. Subsequently, why RANS is still frequently used and whether this is justified or not is illustrated by examples for five application areas in building simulation: pedestrian-level wind comfort, near-field pollutant dispersion, urban thermal environment, natural ventilation of buildings and indoor airflow. It is shown that the answers vary depending on the application area but also depending on other—less obvious—parameters such as the building configuration under study. Finally, a discussion and conclusions including perspectives on the future of LES and RANS in building simulation are provided.     

Cadmium assimilation in the terrestrial isopod, Porcellio dilatatus--is trophic transfer important?

Terrestrial isopods have become important tools for the ecotoxicological assessment of metal-contaminated soils. Their value as an invertebrate model is partly because of their extraordinary capacity to bioaccumulate toxic metals from the environment. Replication of this accumulation process in the laboratory has in the past relied on the amendment of organic food substrates through the addition of inorganic metal salts. However, the bioavailability of the metals when presented through doping regimes may differ from the bioavailability of metals in nature, because over time metals become biologically compartmentalised and form complexes with organic molecules. This study examines the differential bioavailability of Cd to the terrestrial isopod, Porcellio dilatatus, when presented as either a Cd-amended diet or pre-incorporated biologically into lettuce (Lactuca sativa). Isopods were either provided with lettuce contaminated superficially with Cd(NO(3))(2) or lettuce grown hydroponically in growth media containing 100 microM Cd(NO(3))(2). Assimilation efficiency of Cd was greater among isopods that were fed the amended diet (71%, S.E.=7%), than among isopods feeding on biologically contaminated lettuce (52%, S.E.=5%) and demonstrates that speciation of Cd is likely to influence the rate of Cd assimilation and accumulation in a laboratory test.     

Public Participation and New Urbanism: A Conflicting Agenda?

The challenges to public participation in planning are numerous. Inclusive and equitable processes are recognised as an ideal in much planning theory and practice, yet this ideal is increasingly difficult to realise in today's societies that comprise diverse and multiple publics. Within the wider sustainability debate, “New Urbanism” has emerged as a pragmatic alternative to conventional low-density development. Concomitant with a range of prescribed physical outcomes, the New Urbanism movement advocates a process of “citizen-based participatory planning and design”. Charrettes, with urban design workshops, are the favoured tools for achieving this goal. However, it is argued that the adherence to a single type of participatory tool can be inconsistent with accepted ideals of participation processes and has several implications. Of particular concern is the role of the charrette planner or facilitator, a figure who has the potential to manipulate the public because of his/her inevitable allegiance to the New Urban agenda. In addition, the examination of a charrette process in a small New Zealand town raises several broader questions about the ability of the approach to address issues of inclusiveness and the recognition of difference, two fundamental elements of good participatory processes.     

Path Dependence and Critical Junctures in Irish Rental Policy: From Dualist to Unitary Rental Markets?

Ireland is categorised as an example of the dualist rental system in From Public Housing to the Social Market—Kemeny's (1995) landmark comparative study of rented housing. This article, which examines the historical development of public subsidisation of housing and regulation of tenants' occupancy rights in Ireland, argues that contrary to Kemeny's (1996) assumption, the dualist model has recently unravelled in this country and been replaced by an embryonic unitary rental model. This is evidenced by increasing tenure neutrality of government housing subsidies; equalisation of the secure occupancy rights and minimum standards regulations across most of the rented sector and the recent decline of home ownership and expansion of renting for the first time since records began. Using ‘path dependence’ and other concepts from the historical institutionalist literature, the reasons for these developments are explored as are their implications for Kemeny's (1995) thesis.     

Spatial Assimilation in Denmark? Why do Immigrants Move to and from Multi-ethnic Neighbourhoods?

In most European countries ethnic minorities have had a tendency to settle in certain parts of cities—and often in social housing—together with other immigrants in so-called multi-ethnic neighbourhoods. An explanation for this could be low income combined with lack of knowledge of the housing market and discrimination, which limits the housing possibilities for ethnic minorities. Another explanation could be that for different reasons immigrants choose to settle in so-called ethnic enclaves where they can find an ethnic social network, which can support them in their new country. In traditional research literature about immigration it has been shown that for many immigrants living in enclaves has been a temporary situation. The ‘spatial assimilation theory’ says that this situation ends when the family has become more integrated in the new society and then moves to another part of the city. This paper provides evidence to support both explanations of why ethnic minorities move to and from multi-ethnic neighbourhoods.
