APARTHEID WITHIN APARTHEID: AN ASSESSMENT OF OFFICIAL INTRA-BLACK SEGREGATION ON THE WITWATERSRAND,SOUTH AFRICA

Apartheid in South Africa operates at several levels, notably in the policies of state partition and urban residential segregation. The Black population of South African cities resides in racially exclusive townships where the various linguistic groupings are further separated as part of the apartheid policy of state partition. The extent to which linguistic segregation has been enforced in the complex Witwatersrand townships is measured in this paper. The policy has been less effective than other forms of urban segregation, suggesting constraints by the inherited township structures and management problems.     

OVERCOMING THE APARTHEID LEGACY IN CAPE TOWN SCHOOLS*

ABSTRACT. Restructuring apartheid geographies of racial stratification and spatial segregation poses formidable challenges, not least in education. Increasing intraracial inequality also underscores the importance of widening access and opportunity. Although South African education is not constrained by the highly localized control found in the United States and the United Kingdom, school allocation policies and parental choices create geographies that intersect with those of race and residence. Spatial variations critically influence both the impacts of postapartheid policies and the patterns of school desegregation. In this article we explore the spatial impact of inequality, desegregation, and state policies in relation to fourteen secondary schools in Cape Town, distinguishing outcomes that reflect inherited inequalities and current policies from outcomes that reflect individual school strategies. Capital funding is insufficient to change inherited inequalities, and differential fees and fund‐raising capacities perpetuate inequalities in operational resources. Sharing resources, taxing fee income, and a measure of provincial control over feeder areas could reduce inequalities.     

Circulating planning ideas from the metropole to the colonies: understanding South Africa's segregated cities through policy mobilities

In the early part of the twentieth century, South African cities were segregated in accordance with British city planning concepts that embodied the belief that social order can be manipulated through the urban form. This paper surveys the history of South African planning practices to understand the spread of segregation policies and practices. Whereas scholars tend to agree that the apartheid city (post?1948) is a more highly organized and structured version of the colonial city (pre?1910), the literature lacks consensus on the development of the segregated city (1910?1948) within South Africa. How did concepts of segregation circulate and why was it implemented with such consistency? Accordingly, this paper employs concepts of policy mobilities to trace historical configurations in South Africa to international influences. The focus on the circuits of knowledge explains how concepts and designs transplanted from elsewhere helped create the form of South African cities today. Understanding the movement of planning ideas through policy mobilities furthers geographical understandings of historical circulation processes, the role of the local actors, and policy mobilities failure. This history of learning also challenges the assumption that South African cities are unique and in so doing opens the doors for knowledge sharing between postcolonial cities.     

Fuzzy inference guided cellular automata urban‐growth modelling using multi‐temporal satellite images

This paper presents a fuzzy inference guided cellular automata approach. Semantic or linguistic knowledge on urban development is expressed as fuzzy rules, based on which fuzzy inference is applied to determine the urban development potential for each pixel. A defuzzification process converts the development potential to the required neighbourhood development level, which is taken by cellular automata as initial approximation for its transition rules. Such approximations are updated through spatial calibration over townships and temporal calibration with multi‐temporal satellite images. Assessment of the modelling results is based on three evaluation measures: fitness and Type I and Type II errors. The approach is applied to model the growth of the city of Indianapolis, Indiana over a period of 30 years from 1973 to 2003. A fitness level of 100 ±20% with 30% average errors can be achieved for 80% of the townships in urban‐growth prediction.

APARTHEID,URBAN SEGREGATION,AND THE LOCAL STATE: DURBAN AND THE GROUP AREAS ACT IN SOUTH AFRICA

There has been some speculation about the origins of the Group Areas Act (GAA), one of the key instruments used to enforce the ideology of apartheid. This paper examines the origins, development, and implementation of the Group Areas Act in Durban. The key argument of this paper is that the anti-Indian agitation of the Durban City Council and its White electorate played an important role in the development of the legislation. Whites in Durban were at the forefront of calls for the compulsory segregation of Indians because this group presented a serious threat in terms of competition for social and economic space. The local state in Durban worked closely with the central state and played a key role in the formulation and implementation of the Group Areas Act. In all of the race zoning proposals for the City of Durban, the views of the White electorate were considered by the local state, but those of the disenfranchised Indians were disregarded. The local state in Durban was, however, forced to review its race zoning plans when it became apparent that the central state expected it to bear the costs of uprooting hundreds of thousands of people. Despite numerous appeals by the local state and Indian political and civic organizations, the spatial impress of the central state was imposed upon the local state.

SOUTH AFRICA'S NATIONAL HOUSING SUBSIDY PROGRAM AND APARTHEID'S URBAN LEGACY

This study examines the ability of the South African housing subsidy program to hasten desegregation and integration of South Africa's cities. It reviews the basic elements of recent local government reform and housing subsidy legislation. Highlighting the experiences of the city of George, it notes that in order to achieve a rapid provision of housing, the racial division of urban areas has initially been perpetuated.

Spatial concentration patterns of South Asian low-skilled immigrants in Oman: A spatial analysis of residential geographies

Oman is a major recipient of South Asian labor immigrants, and correspondingly, the demographic statistics reveal that the non-Omani populations primarily are constituted of the Asians. This research examines whether the largest immigrant groups (Indian, Bangladesh, Pakistani and Sri Lankan) in Oman form residential clusters according to their work skills (higher and lower skills). The residential geographies of South Asian workers at the subnational administrative boundaries have been investigated in the current study. Empirically, the study employs the use of Location Quotients (LQ) and Entropy Index within the GIS environment to spatially analyze the immigrant residential distributions based on their work skills. Interestingly, the findings of this research confirm the primary influence of geography on the residential patterns of the low-skilled immigrants. Initially, Al-Batnah governorates constituted the main destinations of low-skilled Bangladeshis. Further, the research also highlights significant clusters of Indian and Pakistani high-skilled immigrants in urban residential communities within the Muscat governorate. In addition, the South Asian are found to be a relatively constant stream of immigrants to inhabit the Omani urban areas, with employments in various public and private economic sectors (e.g. educational, health, manufacturing, finance, business etc.). This concentration pattern of low skilled immigrants is attributable to the need to labor shortages of native populations in certain jobs. The research results also indicate that the rural and suburban communities of Al-Batnah coastal plain not only have a greater number of low skilled immigrants but also display equitable distributions of the four South Asian groups in the residential settlements. For policy makers, it is imperative to understand the spatial patterns of low and high-skilled immigrants in Oman, which exert several geographic, economic, social and demographic implications. The significant role of immigration in development necessitates the identification of the predominant destinations for immigrants. It has been observed that the immigrants are crucial to several sectors of Omani urban economy, and urban areas with a large number of immigrants are more likely to grow and expand faster. In addition, the immigrants’ laborers offer potential economic benefits to the host country, which include fostering entrepreneurial activities, small businesses and reducing wages, especially in unskilled jobs. Despite the negative impacts of immigration (e.g. losing national cultural and creating socio-spatial segregation), the diverse and distinctive locational patterns of immigrant groups in Oman contribute crucially to the socioeconomic development and immigration policy. Yet understanding of the spatial dynamics of immigration in structuring the Omani regions and its influences remains very limited. Thus, further research accounting for the different spatial and attribute ancillary data is necessitated.     

Reimagining e-waste circuits: calculation,mobile policies,and the move to urban mining in Global South cities

In this article, I describe how calculative practices of enumeration and visualization mobilized by policy actors to govern the multiple mobilities of e-waste and its re-materialization as value in the informal-recycling economies of Global South cities have resulted in e-waste being recalibrated as an “urban mine.” To properly govern and fully exploit e-waste qua urban mines, policy actors have developed the Best-of-2-Worlds (Bo2W) model. I show that the antecedent of the Bo2W model is the Clean e-Waste Channel implemented in Bangalore, India’s “Cyber City,” which has retroactively been recast as the first successful implementation of the Bo2W model. While policy actors mobilize Bangalore’s success to boost this model and facilitate its mobility to other Global South cities, I conclude by offering a critical assessment of the Bo2W model for the prospects of informal recyclers in Global South cities and the creation of uneven geographies of e-waste toxicity.     

ASSURE: a model for the simulation of urban expansion and intra-urban social segregation

Numerous cities in developing regions worldwide are expanding at a tremendous rate. This requires adequate strategies to address the needs of these growing cities with diverse populations. Nonetheless, the development of urban policies is often hampered by the lack of reliable data or insight in the socio-spatial dynamics of this urban expansion. This paper therefore presents ASSURE, a spatially and temporally explicit model that can simulate urban growth and intra-urban social segregation, taking into account alternative policy strategies and expected social dynamics. The model has a flexible structure that allows incorporating specific city conditions that influence residential decision-making and adapting the simulation to the data available. This, in combination with the transparent model structure, makes ASSURE a potentially valuable decision support tool for urban planning. The potential is demonstrated with an example where the urban growth of and social segregation in Kampala (Uganda) is simulated based on (semi-)quantitative and qualitative data for ca. 800 households collected through interviews. The results of the simulations show that depending on the scenario, the spatial segregation and accessibility problems will evolve highly differently.     

The concentration of urban crime in space by race: evidence from South Africa

Crime inequality in neighborhoods by race is blamed on social inequalities borne out of segregation and economic discrimination. South Africa is a country synonymous with racial-spatial segregation and discrimination as a result of legislatively enforced policies of the former apartheid government. This study examines whether urban crime inequalities by race exist in the city of Tshwane, South Africa and identifies the empirical causes of these crime inequalities. Violent and sexual crime was found to concentrate in Black African neighborhoods, while property crime was concentrated in neighborhoods classified as “Mixed”. The causes of crime in neighborhoods were found to vary across racial groups with results suggesting non-uniformity in the extent to which the various constructs impact crime based on race. The results challenge the notion that segregation and economic discrimination uniformly impacts affected communities. Explanations for the findings are provided in the context of an increasingly eclectic post-apartheid South African city.

基于企业母子联系的中国跨国城市网络结构——以中韩城市之间联系为例

从基于企业活动为城市经济活动的主要动因、企业组织联系为城市网络基础的认识出发,以企业跨国母子组织联系为根据,建立网络基本要素和联系密度等概念与指标。以中韩城市联系为例,分析了中国城市跨国网络结构特点。结果表明:跨国城市网络不断扩大的同时,网络基本要素分布呈现区位倾向性,集聚于环渤海和长三角;城市对和结点城市联系密度位序—规模分布显著,形成青岛、上海、北京、天津与首尔主导轴和青岛、天津、上海、北京等主导结点;城市对和结点城市的联系密度规模位序不断调整,同时在高位序群中保持相对稳定性;结点城市呈现专门性、综合性的分化,如北京和上海显示综合性,青岛和天津显示专门性等;受企业母子相互关系影响网络联系键具有矢量性,进而结点城市中形成源结点和受结点之分。     

中国小城镇镇区土地利用结构特征

小城镇镇区土地利用结构是小城镇社会经济发展的基本空间映射,是小城镇规划管理的关键问题之一,合理的空间结构能够促进小城镇功能的发挥和用地效益的提升。当前该领域的研究主要侧重某一区域或者某一类型的研究,全国层面的调查研究较少,造成当前理论研究结论的普适性和可推广性较低。采用2016年住房和城乡建设部全国121个镇的调查数据,对中国小城镇镇区土地利用结构特征进行深入分析并揭示其特征形成机制。研究发现:①由于镇区人口少、规模差异小,不同人口规模小城镇之间的土地利用结构有差异,但是不突出。②多数小城镇受镇区产业空心化影响,用地结构的居住服务功能较为显著。③小城镇镇区用地结构与区域经济发展水平、工业化发展水平密切相关,经济发展水平高的地区,工业用地占比高。④受大城市辐射和虹吸作用影响,近郊小城镇土地利用结构的城市化现象明显。⑤土地所有制与用地结构密切相关,国有土地占比高的镇,公共设施用地比例高。本研究对于丰富和完善中国小城镇理论研究具有重要的理论价值,对于指导小城镇规划建设具有重要的实践价值。     

Urban development policy in India with special reference to Himachal Pradesh

This paper addresses the following questions: 1) What have been the government policies, programs, and perceptions dominating the urban development scenario in India? 2) What has been the outcome of these policies and programs of urban development? 3) What should be the strategy of future urban development with reference to the Indian hill state of Himachal Pradesh? The paper critically evaluates the Indian ethos pertaining to the urbanization process, urban development policies pursued in the Five Year Plans, the current thinking on urbanization, and the main issues in urban development. It has been observed that not only is the urbanization level in Himachal Pradesh quite low, but also that the urban development here suffers from a number of serious problems. Acute shortage of building space, limited capacity to mobilize resources from their own sources, overcrowding, and slum dwelling are some such problems. Unfortunately, urbanization has not been visualized as generative of economic growth and employment opportunities both at the state and national government levels. Therefore, the major thrust of Plan policies has been to arrest rural-urban migration. However, recently there has been a desire to manage urban affairs through a new policy seeking production efficiency and cost effectiveness.     

Exports and Growth: Learning from the Case of Southern U.S. Metropolitan Areas

The relationship between exports and economic growth is a paradigmatic element of modern economic growth policy, despite the absence of strong evidence of a connection. Until recently, data on export production prevented an extensive empirical analysis of metropolitan-scale trade. This article examines the export growth dynamics across large metropolitan statistical areas (MSAs) within the southern United States, a region that has been impacted by economic globalization. These analyses found that some Southern metropolitan areas differ from regional and national averages in selected measures of export performance. Additionally, the export performance of Southern cities was not correlated with all indicators of economic development. This article concludes that export dynamics should be viewed increasingly from an urban frame, with particular emphasis on the production of globally consumed knowledge products and advanced manufacturing. Moreover, export policy should be directed toward the individual strengths of urban regions.     

Measuring the Size,Scope, and Location of Civil Society Organizations in Johannesburg's Food System

Food security civil society organizations (FSCSOs) are key institutional players in the Global South, yet researchers have not adequately examined their size, scope, or location within urban areas. To fill this gap, this article analyzes Johannesburg's FSCSOs using quantitative survey data and spatial analysis. Data findings suggest that FSCSOs’ resources are unevenly distributed across Johannesburg, with larger, privately resourced FSCSOs located in white suburbs and smaller, unstable, turnover-prone FSCSOs located in black townships and informal settlements. Overall, these data suggest that the city's network of FSCSOs is spatially polarized and weakest in areas where food insecurity is the greatest.     

Boston’s Olympic bid and the evolving urban politics of event-led development

The sports mega-events industry is in the midst of a significant reorganization, and the urban politics of event-led development planning is increasingly tumultuous. Three trends stand out: (1) the mega-events industry has been professionalized through consultancies, sports federations' urban policy programs, and city-to-city knowledge-sharing partnerships. (2) Critics of mega-events have been successful in drawing attention to state intervention and public subsidies involved in mega-event planning. (3) A proliferation of anti-bid social movements has pursued a form of urban politics, which more aggressively questions the legitimacy of using mega-events to pursue urban development. I evaluate the implications of these trends with a case study of a bid to host the 2024 Summer Olympic Games in Boston. The failure of the Boston bid illustrates increasing tensions between cities and the mega-events industry.
