Towards the Creation of Healthier City Neighbourhoods for Marginalised Communities in South Africa: a Case Study of the South Durban Industrial Basin in the City of Durban

This paper critically evaluates efforts to mitigate the adverse effects of pollution on residential communities that are located next to polluting chemical industries in the South Durban Basin area, in the city of Durban, South Africa. The economic agenda ignored socio-environmental imperatives as poor residential communities and polluting chemical industries were juxtaposed, which made the area prone to environmental and health hazards. Empirical research is conducted focusing on the relations among industry, the people, housing, health and the neighbourhood built environment. The paper notes that efforts to create healthier livable city neighbourhoods in Africa, and South Africa in particular, are hampered by the superimposition of industrial capitalism over social and environmental aspects of sustainable development. In this context, the paper argues marginalised neighbourhoods need to proactively articulate their environmental concerns in ways that foster the cooperation and remedial action of other stakeholders of urban governance especially the state and private sector.     

Assessing economic,social and environmental impacts on housing prices in Hong Kong: a time-series study of 2006, 2011 and 2016

Given Hong Kong’s unique high-density urban environment and limited land resources, more and more general public has been concerned about the living quality. Based on three waves of census data (2006, 2011 and 2016), combined with our spatial–temporal urban environmental database consisting of three local datasets of urban climate and air quality, this paper assesses the impacts of social, economic and environmental factors on the logarithm of housing prices in Hong Kong through linear regression analysis. Specifically, both supply- and demand-side economic factors have significant impacts on housing prices. Demographic factors are not as significant as expected in affecting housing prices. Transportation factors have more significant effects in the short run than in the long run. Environmental factors, including the number of hot night hours, Annual Air Quality Index (AAQI) of nitrogen dioxide (NO₂) and particulates with particle sizes less than 10 microns (PM₁₀), significantly affect housing prices over time. The results have important implications: current policy instruments to prevent housing price escalation are focused on increasing property tax or land supply (economic factors), while little attention is paid to social or environmental factors, which are geographically heterogeneous. Our findings suggest that housing provision in the New Territories may be a feasible solution to alleviate the housing crisis as its demographic pattern, transportation connectivity and air quality are significantly different from Hong Kong Island or Kowloon Peninsula. In regard to urban environmental problems brought by the high-density development in Hong Kong despite land-use saving, intensified urban infrastructure and promotion of public transportation, our study contributes to the understanding of its housing price dynamics from a more holistic perspective by comparing the impacts of economic, social and environmental factors.

Changing urban housing form and organization in Nigeria: lessons for community planning

There has been very little research interest in historically changing patterns of urban housing form and organization and the quality of life experienced by ordinary people in designed settings. This is despite the arguments of humanistic geographers and contemporary environmental psychologists that the behavioural and socio‐cultural aspects of built form imbue environments with meanings and help to create a sense of place. This paper focuses on the development of housing forms in Nigerian cities, including the cultural motifs and the economic circumstances that have shaped their evolution over time. The analysis of pre‐colonial traditional housing forms at the core of cities is presented first followed by an appraisal of newer developments at the suburbs that were stimulated by colonial and post‐colonial market‐driven economies. Drawing on the divergent examples of the transition from traditional to modern urban housing forms, the paper reveals that social changes, particularly the shift from traditional communal family values to more Western ways of life, have had variegated impacts on building forms and residential layouts. One of these is inhabitants’ alienation from the urban environment and the seeming identification with home places of origin outside the city. The paper argues that while this situation poses a major challenge to urban planning in post‐colonial Nigeria, professional planning practice seems to have demonstrated little interest in what people think or feel about places. Ways in which new housing forms may be organized and incorporated into future programmes of urban development to promote communal belonging to Nigerian cities are articulated.     

Housing Reform and its Impacts on the Urban Poor in China

Housing provision in Chinese cities has experienced many changes since 1979 when the country embarked on major economic reform. During the late 1980s and the 1990s many publicly owned houses were sold to their existing tenants or other public sector employees. Large numbers of new houses were built by commercial property developers for the emerging urban housing market. As a result, new patterns of residents have emerged. Housing areas of different standards for different social groups became a dominant feature of large Chinese cities at the end of the 1990s. Will the urban poor benefit from these changes and what is their housing situation like under the reformed system? This paper addresses these questions by examining the nature of the emerging urban poor and their accessibility to housing. It involves an assessment of the implications of recent housing reform policies for the disadvantaged groups. The paper identifies two major groups of urban poor in Chinese cities: the poor among the official urban residents and the poor rural to urban migrants. It concludes that while housing problems of the official urban poor have been recognised, there is no formal policy in relation to housing provision for the unofficial poor.     

Green Economy: A Strategy to Alleviate Urban Poverty and Safeguard the Environment? KwaZulu-Natal,South Africa

The global failure to develop in a sustainable manner has led to attempts to adopt green economy approaches in the context of poverty alleviation and sustainable development. Given South Africa’s high carbon footprint and other negative environmental externalities, the government, in partnership with civil society and the private sector, is taking steps to green its economy. The efforts range from large-scale solar installation projects to small-scale grassroots level projects where green jobs are created for the poor, predominantly women, by paying them for environmental services. This paper addresses if and how green economy can be used to alleviate poverty and protect the environment at a grassroots level. In a project under the management of a local environmental non-governmental organisation (ENGO), poor urban women in Pietermaritzburg, South Africa, are utilising the concept to generate income, improve their livelihoods and contribute to environmental sustainability. Green economy is in some ways addressing the gendered social and environmental externalities of urbanisation, wherein women are differentially poor and the environment is neglected in economic development. Left with few other options, the urban poor are using an ENGO and its green economy programme as a mechanism to lift themselves out of poverty, while indirectly managing the environment.     

Residents’ relationship with green infrastructure in Cosmo City,Johannesburg

Scholars have expressed concerns about environmental sustainability in low-income housing development in South Africa in terms of the poor households’ relationship with, access to and benefit from natural ecosystems and green spaces. Using a qualitative research approach – discourse-based methods (semi-structured interviews, focus group discussion and transect walks), this paper shows how low-income households in Cosmo City, Johannesburg (South Africa) benefit from green infrastructure at the domestic, neighbourhood and riparian scales. The central lesson from this case is that landscape/urban design, planning and management must recognise and respond to socio-economic and socio-ecological realities and dynamics inherent in the ways low-income households relate with green infrastructure.     

Accessibility of Services and Facilities for Residents in Public Housing in Urban Areas of Ogun State, Nigeria

Against the backdrop of the need to improve accessibility of services and infrastructural facilities for urban residents in Nigeria, this study examined the accessibility of services and facilities for urban residents in newly constructed public housing in Ogun State, Southwest Nigeria. The study was based on household surveys and data were collected from 452 respondents in nine public housing estates constructed between 2003 and 2010 in urban centers in the study area using structured questionnaire and observation schedule. It was observed that although the majority of households in the housing estates have good access to human waste disposal system, accessibility to refuse bins, treated water, electricity, and public transport services as well as educational, shopping, recreational, healthcare, drainage, and other vital facilities is poor. One instructive finding of this study is that more emphasis is given to the production of dwelling units than accessibility to basic services and facilities for residents in public housing schemes in the study area. The paper suggests that to improve the quality of public housing and living standard of residents, policy action is required to compel public housing developers to provide basic services and facilities in housing schemes in Nigerian cities.     

Parisian eco-districts: low energy and affordable housing?

This paper examines how policies and practices for affordable housing in Paris, especially ‘green’ housing for the poor, are being subverted to retain or attract the middle class: the ‘greentrification’ of lower-class neighbourhoods. From the 1960s onward, many middle- and working-class households have left Paris due to de-industrialization and the city’s high housing costs. To bring these middle classes back, the municipality initiated a policy calling for increased social diversity, using social housing as its main policy tool. In France the provision of public housing is legally mandated, and compared with international standards, the income ceilings for gaining access to it are high. Thus, municipalities may pursue urban renovation and construct social housing for the middle class to replace substandard buildings occupied by low-income populations. The Paris municipality has established ‘green’ residential eco-districts known as ‘eco-quartiers’. In the national eco-district programme, the neighbourhoods must meet environmental performance criteria, show potential for economic development, and provide social and functional diversity. Thus, housing location and price must fit the needs of the existing residents. However, most ‘green’ subsidized housing in Paris is for the middle class. Social diversity has become a means of redistribution: more middle class and fewer poor people.     

Modern housing estates and the production of the Brazilian city (1937–1960)

ABSTRACT

The social issue of housing has been a focal point in the criticism of Brazilian modernity, and it still plays a central role in the balance of Brazilian democracy. This paper discusses the investments in modern housing made by the welfare system in Brazil and which are related to the country's transition toward an urban society in the late 1930s. The analysis concludes in the 1960s, when these investments ended. The relationship between housing and the industrial economy characterized urban development in Brazil in this period. The latter saw direct state intervention in overseeing the building of houses for urban workers. This process started during Brazil's authoritarian regime [1937–1945], just as the cycle of Brazilian industrial democracy began in the mid-forties. The state housing policy worsened the urban crisis while also increasing the real estate market. It triggered several major controversies including an imbalance in urban classes associated with exclusively rich and poor neighbourhoods. The extension of the housing policy and social benefits to all citizens triggered tensions. These findings explain the challenges of political process, the changes in the housing policy and the swelling of Brazilian urban society.     

Social Capital and Migrant Housing Experiences in Urban China: A Structural Equation Modeling Analysis

Rural–urban migration and housing for the urban poor have attracted worldwide attention from both scholars and policy makers. In China, empirical studies have revealed tremendous discrimination experienced by temporary migrants in the urban housing system, but most have emphasized constraints by formal institutions such as the hukou system. This paper adopts a sociological theory of social capital and employs structural equation modeling to investigate, simultaneously, the impacts of social capital on migrants' housing experiences in Chinese cities, as well as the causal relationships between a migrant's socioeconomic status and his/her social capital profile. Based on data from a twelve-city migrant survey conducted in 2009, statistical analysis revealed that, although migrant workers in general possess a small and truncated network of social ties in the city, those migrants who are connected to individuals with local hukou, rather than connected to more people, have higher access to formal housing and tend to enjoy better housing conditions.     

Hear no housing, see no housing: Immigration and homelessness in the new South Africa

The housing crisis in South Africa has received an enormous amount of attention from governments, NGOs and academics. One issue that has been virtually ignored, however, is housing for non-citizens – particularly poor, undocumented migrants from other parts of Africa who are arriving in the country in search of work and accommodation. This paper explores official government policy on the issue as well as ground-level attitudes of citizens and non-citizens. Although little has been done to address this potentially explosive issue, there are grounds for optimism for progressive policy development.     

Achieving a Socio-Spatial Mix? Prospects and Limitations of Social Housing Policy in Santiago de Chile

In the Chilean housing sector, the combination of free-market imperatives guiding investment decisions and a long tradition of social housing subsidies has generally had remarkable success in quantitative terms but has also contributed to the large-scale segregation of poor families on the urban periphery. With the goal of a better socio-spatial mix and, ultimately, social integration, the Chilean government recently revised its guidelines for housing subsidies, promoting small-scale social housing in central locations. This paper examines the early effects of this new housing policy in a cluster of the so-called “pericentral” municipalities in Santiago de Chile. Specifically, it raises the question of whether the policy has a chance of achieving its objectives in light of prevailing free-market conditions. We demonstrate strong interrelations between the current dynamics of real-estate investment and government-led housing programs which together continue to promote uneven socio-spatial development and segregation of the urban poor on a smaller scale.

Tropical Architecture and the West Indies: from military advances and tropical medicine,to Robert Gardner-Medwin and the networks of tropical modernism

The history of modern Tropical Architecture has largely focused on the region of West Africa, however this paper demonstrates that additional strains were being developed elsewhere, preceding the African examples. Indeed, Tropical Architecture, far from being a mid-twentieth century phenomenon, has a much longer history, stretching back into the colonial settlements of the eighteenth century and continued by the tropical medicine contributions of the early twentieth century, particularly in the British West Indies. This paper considers some of these early examples, before investigating the work produced by Robert Gardner-Medwin, along with his small team that included Leo De Syllas and Gordon Cullen, during the Second World War in the West Indies. Their work there as part of the ‘development and welfare’ programme was considered, ‘building research’, concerned with materials, pragmatic decisions and housing, and, whilst it was unacknowledged at the time, was clearly indebted to the earlier military and hygiene models. Nevertheless, the work they undertook was highly influential in the development of modern tropical architecture, and in particular the buildings that were later produced in West Africa: it helped to formalise this canon, and unified the previously fragmented and disparate out-workings of the Metropolis. Gardner-Medwin, therefore, can be considered an agent of Empire, a key-player in the extension of British architects operating as the knowledge makers, not only in the period of colonial rule, but crucially, afterwards. This is further manifest through his involvement in UN housing missions to South East Asia and his contribution to the Tropical Architecture Conference held at University College, London, in 1953.     

Infrastructure and Poverty Reduction: Implications for Urban Development in Nigeria

The paper investigates the impact of infrastructural development on poverty reduction in Nigeria. Specifically, the relative effects of physical and social infrastructure on living standards or poverty indicators are examined, with a view to providing empirical evidence on the implications of increased urban infrastructure for the urban poor. The paper employs secondary data for the period 1970:1 to 2005:4 and the Structural Vector Autoregressive technique is adopted in the analysis. The study unequivocally finds that infrastructural development leads to poverty reduction. Results also show that though infrastructure in general reduces poverty, social infrastructure explains a higher proportion of the forecast error in poverty indicators relative to physical infrastructure. This suggests that massive investment in social infrastructure in cities would drastically reduce poverty in the urban areas.     

Residential fencing and house gating: An overview of social inequality and urban insecurity in Ilorin,Nigeria

Socio-spatial territoriality manifests as residential fencing and gating and are common features of urban living environments, although the mechanism for determining the best social-mix in housing development is grossly missing. This study aims to determine the social-mix in housing that best mitigates urban insecurity as outcomes of social inequality because of the continually widening gaps between the social classes. The study was carried out in the urban areas of Ilorin in Nigeria, through systematic sampling. Close-ended questionnaire (N = 247) on the phenomena was administered in each building. Results suggest that two types of social-mix in housing can have significant impact of reducing urban insecurity. These are the low status and the middle status, and the upper status and the upper–upper status. Therefore, the study concludes with recommendations in these directions.

Low-Income Access to Urban Land and Housing in Botswana

Like most developing countries, Botswana—a middle-income country—has experienced rapid urban growth, which has brought in its wake many social and economic problems. One of the key challenges has been the lack of access to land and housing for the poor who have moved into the urban centres in large numbers in search of employment and economic survival. Many programmes and strategies have been introduced by both central and local governments to address this problem. These include: squatter settlement upgrading; public housing through site, service and self-help housing; subsidised plot allocation; financial incentives for housing construction, etc. Many challenges have hampered the implementation of these strategies and programmes including fast urbanisation, which outstrips supply of land and housing for most urbanites; unaffordability of many of these schemes; poor targeting; high defaulting rates and poor management of these schemes. This paper calls upon the government, the private sector and local communities to devise holistic solutions to enable low-income households to procure decent accommodation in urban areas.     

混合式住区对中国大都市住房建设的启示

鉴于中国大都市中日益显著的居住隔离现象,对于住房选择的干预越来越依赖市场,而现有住房政策、土地政策和城市规划忽视了住房和社区的社会意义,应当在住房发展中让不同收入阶层、不同类型家庭在社区和邻里层面混合居住,享有同等的社会资源,使社会各阶层在城市空间层面上处于相对平衡的状态,减轻由于居住空间分异所引发的社会问题。这一理想的实现必须依靠适度正确的制度干预。通过介绍美国、香港等国家和城市混合式住区发展的经验,引发更多从政策和实践等各个层面对中国大都市住房建设的探索。
