Academic literature on the topic 'Metropolitan areas – South Africa – Gauteng'

This note offers a critical reflection of the recent landmark decision in City of Johannesburg Metropolitan Municipality v Gauteng Development Tribunal which lay to rest the negative consequences of employing the DFA procedures of the Development Facilitation Act 67 of 1995 (DFA) alongside those of the provincial Ordinances to establish townships (or to use DFA parlance, “land development areas”). The welcome and timely decision in City of Johannesburg Metropolitan Municipality v Gauteng Development Tribunal has declared invalid chapters V and VI of the DFA. Moreover, it has formalised planning terminology in South Africa, delineated the boundaries of “municipal planning” and “urban planning and development” as listed in Schedules 4 and 5 of the Constitution of the Republic of South Africa, 1996 and, in the process, clarified the structure of planning law. This note examines the decision of the SCA and focus on the role it will clearly have in reforming some of the law relating to planning. It considers the facts of the case, uncertainties around terminology, the structure of planning in South Africa, the content of municipal planning, the role of the DFA and the consequences of the declaration of invalidity by the SCA.

Abstract. We present a comprehensive overview of particulate air quality across the five major metropolitan areas of South Africa (Cape Town, Bloemfontein, Johannesburg and Tshwane (Gauteng Province), the Industrial Highveld Air Quality Priority Area (HVAPA), and Durban), based on a decadal (1 January 2000 to 31 December 2009) aerosol climatology from multiple satellite platforms and detailed analysis of ground-based data from 19 sites throughout Gauteng Province. Satellite analysis was based on aerosol optical depth (AOD) from MODIS Aqua and Terra (550 nm) and MISR (555 nm) platforms, Ångström Exponent (α) from MODIS Aqua (550/865 nm) and Terra (470/660 nm), ultraviolet aerosol index (UVAI) from TOMS, and results from the Goddard Ozone Chemistry Aerosol Radiation and Transport (GOCART) model. At continentally influenced sites, AOD, α, and UVAI reach maxima (0.12–0.20, 1.0–1.8, and 1.0–1.2, respectively) during austral spring (September–October), coinciding with a period of enhanced dust generation and the maximum integrated intensity of close-proximity and subtropical fires identified by MODIS Fire Information for Resource Management System (FIRMS). Minima in AOD, α, and UVAI occur during winter. Results from ground monitoring indicate that low-income township sites experience by far the worst particulate air quality in South Africa, with seasonally averaged PM10 concentrations as much as 136% higher in townships that in industrial areas. We report poor agreement between satellite and ground aerosol measurements, with maximum surface aerosol concentrations coinciding with minima in AOD, α, and UVAI. This result suggests that remotely sensed data are not an appropriate surrogate for ground air quality in metropolitan South Africa.

Abstract. We present a comprehensive overview of particulate air quality across the five major metropolitan areas of South Africa (Cape Town, Bloemfontein, Johannesburg and Tshwane (Gauteng Province), the Industrial Highveld Air Quality Priority Area (HVAPA), and Durban), based on a decadal (1 January 2000 to 31 December 2009) aerosol climatology from multiple satellite platforms and a detailed analysis of ground-based data from 19 sites throughout Gauteng. Data include Aerosol Optical Depth (AOD550, 555) from Aqua (550 nm), Terra (550 nm), and MISR (555 nm) platforms, Ängström Exponent (α550/865, 470/660) from Aqua (550/865 nm) and Terra (470/660 nm), Ultraviolet Aerosol Index (UVAI) from TOMS, and model results from the Goddard Ozone Chemistry Aerosol Radiation and Transport (GOCART) model. Results in Cape Town are distinct, owing to a typically clean, marine airmass origin and infrequent continental influence. At continentally-influenced sites, AOD550, AOD555, α550/865, α470/660 and UVAI reach maxima (0.12–0.20, 1.0–1.8, and 1.0–1.2, respectively) during late winter and early spring (August–October), coinciding with a period of enhanced dust generation and the maximum frequency of close-proximity and subtropical fires identified by MODIS Fire Information for Resource Management System (FIRMS). The adjacent metropolitan and industrial Gauteng and HVAPA areas have been identified as a megacity based on NO2 concentrations, but AOD is a factor of 3–6 lower than other megacities worldwide. GOCART results suggest that the contributions of organics and black carbon to AOD are significantly enhanced during biomass burning season (ASO), but that sulfate is the most significant contributor to AOD (~70–80%) through the rest of the year. Dust appears to be underestimated by GOCART emissions inventories at continentally-influenced metropolitan areas of South Africa. Ground monitoring sites were classified according to site type: (1) township and informal settlement sites with domestic burning influence, (2) urban and suburban residential sites with no domestic burning in the immediate vicinity, (3) industrial sites, and (4) one traffic site situated at a major freeway interchange. PM10 concentrations in township areas are 56% higher than in developed residential areas and 78% higher than in industrial areas as an annual average, with PM10 in townships 63 and 136% higher than developed residential and industrial areas, respectively, in winter (June, July, August). Monthly PM10 and PM2.5 concentrations reach annual maxima during winter at all sites except in industrial areas. At industrial sites, maxima in PM10 and PM2.5 tend to occur during summer (December–February), when photochemical generation of secondary aerosol is expected and when deep and unstable boundary layers allow high stack emissions (emitted above the boundary layer during winter) to reach the ground in close proximity to point sources. Diurnal profiles of PM10 and PM2.5 display maxima during morning (06:00–09:00 LT) and evening (17:00–22:00 LT) at nearly every site – especially during winter – and underscore the importance of domestic burning as a major source of primary particles. Multi-year averages indicate that evening maxima at some township sites average in excess of 400 μg m−3. These results from the urban/industrial Gauteng area quantitatively confirm previous studies suggesting that the lowest-income populations of South Africa experience the poorest air quality, and demonstrate that domestic burning results in frequent exposure to high concentrations of particulate pollution in the region comprising the cities of Johannesburg and Tshwane. While remotely-sensed data are frequently used as a proxy for ground air quality, we report poor correlations between PM concentrations and satellite parameters and suggest that this practice is not appropriate in metropolitan South Africa. Disagreement between satellite and ground data may be attributed to a number of factors: (1) vertical inhomogeneity and stratified pollution layers aloft during much of the year, (2) extremely shallow winter boundary layers, (3) discrepancy between satellite passover times and elevated diurnal PM concentrations, and (4) poor spatial resolution of satellites compared with highly localized PM sources. While remotely-sensed data provide a good picture of regional, seasonal properties of column aerosol, a complete understanding of South Africa's air quality at the ground will necessitate more extensive monitoring at the ground and intensive, multi-platform campaigns to understand the relationship between ground and satellite data.

The sprawled nature of major South African cities can be attributed to a variety of reasons. The 1994 (post-apartheid) political shift, however, prompted cities and regions to plan for more equitable and accessible cities. Together with its three metropolitan municipalities, the Gauteng Province proved to be a pioneer in adopting an urban growth management approach (the Gauteng Urban Edge). Against the backdrop of a Provincial Spatial Development Framework, a Provincial Urban Edge was delineated within which local authorities were awarded the opportunity to refine a custom-made growth management strategy. In the absence of clear provincial direction, these strategies achieved various levels of success. This paper explores the urban growth management movement, its approaches and its expressions as witnessed in the case of Gauteng.

South Africa is a country where first world wastewater treatment technology and management must take into account third world related problems. In the past, the diversity of a large number of local authorities within the PWV area of South Africa aggravated the problem of proper wastewater management. On the East Rand in the Gauteng province of South Africa, the problem was attended to by means of a strategic analysis and strategic plan. In the evaluation of the options, the various wastewater management models in use in various regions of the world were evaluated. The investigation resulted in the formation of the ERWAT wastewater management model and implementation. The paper also evaluates the success of the wastewater management model utilizing the tariff model and other qualitative parameters.

The establishment of a new democracy has created high expectations amongst all the different communities of South Africa. The demand for basic essential services by the previously disadvantaged communities has increased drastically, whilst at the same time, communities from developed areas are expecting and demanding an acceptable level of maintenance and services in their respective areas. Municipalities are in serious distress with regular service delivery protests, huge service delivery and infrastructure backlog challenges (e.g., electricity, roads, housing, water, and sanitation), poor financial management and the inability to execute approved strategies, plans, and programs. This article focused on the municipalities in the Gauteng Province of South Africa and the main objective was to answer the survey question: What prevents Gauteng municipalities to successfully execute its strategies and what can be done to address the situation? The research objectives were firstly, to review the literature and determine the key enablers required for successful strategy execution; secondly, to analyze the findings of the empirical research and to make recommendations towards the improvement of strategy execution within Gauteng municipalities. The third and final objective was to develop an integrated operating framework for strategy execution in Gauteng municipalities. The article concluded by making recommendations towards the improvement of strategy execution within municipalities and developing an integrated operating framework for strategy execution. The results of the literature review as well as the empirical research were taken into account during the development of the integrated operating framework.

Despite a number of initiatives aimed at improving the representation and progressive of women in the law enforcement. Studies continue to document the persistence of gender inequality within law enforcement agencies all over the world and South Africa is not an exception. This article bring to light gender inequalities in the law enforcement sector where women in leadership ranks remains low. Historically, the police career was male-dominated and females were not allowed to work in the police. Therefore, equal gender representation in the workplace should by now be at an advanced developmental stage in South Africa since the abolition of discrimination rules. The Commission on Employment Equity of South Africa reported that women comprised 44.8% of the economically active population, yet males were still in charge of senior management positions in South African industries including the law enforcement environment. The data was collected from female officers from Metropolitan Police departments in Gauteng province. The findings suggest that culture, stereotypes, economic and socio-political dynamics, and physical fitness were perceived as barriers that hindered the representation of women into senior leadership positions.

Background: In addition to increasing access to fresh and affordable produce, home gardening enhances food security. This notwithstanding, there is no evidence of studies that have investigated factors correlated with home gardening in Gauteng Province (GP), South Africa. The present study investigated home gardening across the GP. Methods: Retrospective data of residents of GP (n = 30002) collected by the Gauteng City Region Observatory were used. A binary logistic regression was employed to determine factors correlated with home gardening. Results: Overall participation in home gardening was low (12.37%). If a respondent was a resident of the poorest areas, resided in a house received under the Rural Development Programme, had a borehole/well as the main source of water, belonged to a social club, received a social grant, was >65 years, and rated his/her health as poor, then they were more likely to participate in home gardening. Factors that were negatively correlated with home gardening included if the respondent rented from private individuals and if the respondent’s health status prevented him/her from doing daily work. Conclusion: The low participation levels in home gardening observed suggest the failure of the current policies geared at fostering home gardening in the province. Policy makers and relevant authorities should target identified groups to improve participation in home gardening.

Abstract Growing trends of fear and insecurity in cities have sparked the re-visitation of gating, posing significant problems for citizens and policy makers alike. Gated developments are a global phenomenon occurring in diverse countries in both the developed North and developing South. Metropolitan areas in South Africa have also witnessed a rapid increase in the number and spread of gated developments since the late 1980s. Development of enclosed neighbourhoods has become increasingly popular, gaining widespread support for their utopic lifestyle and safety features. On the whole, high levels of crime and fear of crime have led to the construction of defensible space, in the form of gated developments, resulting in elevated levels of segregation. This paper provides a spatial analysis on gated developments in the non-metropolitan setting of Bloemfontein. The pattern and timeframe of gating in this city is shown to be similar to those found elsewhere in South Africa and, indeed, globally. Overall, it is the contention that gating is a trend not only seen in large metropolitan areas, but across the entire urban hierarchy of South Africa, and, as a consequence, requires investigation far beyond its metropolitan regions to more fully understand gated developments.

Extensive research has been done on the investigation, evaluation, development and management of land underlain by dolomite to prevent the formation of sinkholes and subsidences. Little emphasis is, however, given to the various processes and methodologies with respect to the investigation and rehabilitation of sinkholes or subsidences. In South Africa most sinkholes and subsidences have been recorded on dolomite of the Malmani Subgroup of the Chuniespoort Group on the Far West Rand and in an area south of Pretoria within the City of Tshwane, with numerous studies done on the occurrence of sinkholes and subsidences in these two areas. However, a large number of sinkholes and subsidences have also been recorded on the East Rand in the Ekurhuleni Metropolitan Municipal area, which is the focus of this research. Very little is published on the occurrence of sinkholes and subsidences, the related geological models, investigations and rehabilitation work done in the Ekurhuleni Metropolitan Municipal area. It has been attempted with this thesis to document the various processes and methodologies applicable to the investigation and rehabilitation of dolomite-related sinkholes and subsidences within a non-dewatering environment. This is based on experience gained during the investigation and rehabilitation of various sinkholes and subsidences within the Ekurhuleni Metropolitan Municipal area on the East Rand, over the past ten years. Various methods of investigation, including non-intrusive and intrusive methods have been tried and tested to determine the extent of subsurface erosion within an affected sinkhole or subsidence area. The gravity geophysical method in association with the drilling of percussion boreholes; exposure of the affected area by means of excavation and the use of the Dynamic Probe Super Heavy (DPSH) method, in areas not accessible for a drilling rig where gravel, cobbles and boulders are absent in the subsurface profile; is the most appropriate methods for sinkhole or subsidence investigations on the East Rand. The gravity method is, however, not always successful in delineating narrow grykes in a shallow dolomite environment. The use of a specific method or methods of investigation is prescribed by the accessibility of a site. Accessibility constraints within a build-up area, may lead to the use of an investigation method other than what is generally preferred. The specific method or combination of methods used to rehabilitate a sinkhole or subsidence will depend on the available funds, current and proposed land use, subsurface conditions, accessibility constraints caused by existing infrastructure for equipment and the impact of the rehabilitation procedure on existing infrastructure. The various sinkhole and subsidence rehabilitation methods used on dolomite in South Africa and their applications are discussed, including: the Inverted Filter Method, Dynamic Compaction Method, combination of the Inverted Filter and Dynamic Compaction Methods, Compaction (backfill) Grouting Method, Combination of the Inverted Filter and Compaction Grouting Methods, Combination of the Dynamic Compaction and Compaction Grouting Methods and the use of Self- Compacting Concrete or Soil-cement Mix. Nearly half of the Ekurhuleni Metropolitan Municipal area is classified as dolomite land. A total of 241 ground movement incidents had been recorded, since 2005 to mid-2013. The Ekurhuleni Metropolitan Municipal area of jurisdiction is divided into three regional areas, namely:  Southern Regional area: More than 50% of the region is directly underlain by dolomite and chert of the Monte Christo Formation of the Malmani Subgroup of the Chuniespoort Group. A total of 141 ground movement incidents had been recorded, with all dolomite-related sinkholes and subsidences caused by ingress of water. Approximately 85% were caused by sewer lines, 7% by leaking water lines and valves, 4% by surface water ponding and 3% by concrete stormwater lines.  Northern Regional area: The northern portion of the region is directly underlain by dolomite of the Malmani Subgroup; from west to east by, chert-poor dolomite of the Oaktree Formation, chert-rich dolomite of the Monte Christo Formation, chert-poor dolomite of the Lyttelton Formation and chert-rich dolomite of the Eccles Formation. Dolomite of the Monte Christo Formation is also encountered in the south-eastern portion of the region. A total of 83 ground movement incidents had been recorded. Ground movement incidents are related to both ingress of water and dewatering of dolomite groundwater compartments including the Bapsfontein, Elandsfontein and Sterkfontein-East Dolomite Groundwater Compartments and Sub-Compartment.  Eastern Regional area: More than 50% of the region is regarded as dolomite land, with large portions of dolomite of the Monte Christo Formation and the Oaktree Formation of the Malmani Subgroup covered by the Karoo Supergroup. Dolomite of the Monte Christo Formation also occurs in the south-western portion of the regional area. A total of 17 ground movement incidents had been recorded. None of the recorded ground movement incidents are, however, related to dolomite. Incidents are related to poorely backfilled old wet services, natural erosion of subsurface soils, collapse of shallow coal workings and collapse of mine shafts and ventilation shafts. The sinkhole and subsidence rehabilitation method mostly used in the Ekurhuleni Metropolitan Municipal area is the Inverted Filter Method accounting for 85% of rehabilitation work, 10% for compaction grouting and 5% for the use of the Dynamic Compaction Method. The sinkhole and subsidence rehabilitation method should not be prescriptive, given the vast number of variables involved. A comprehensive understanding of the affected area is essential although for cost effective and practical rehabilitation measures. A site specific set of criteria for the rehabilitation of the features and affected infrastructure must be developed to ensure proper stabilisation and safe future use of the area. Basic principles can however be applied to each sinkhole or subsidence, such as: Ensuring the trigger of the sinkhole or subsidence has been identified and removed; the position and extent of the receptacles have been determined as best as possible and erosion paths sealed; the known eroded area, possible voids and cavities properly backfilled and densified; a proper impervious or engineer designed earth mattress created; ensuring that all affected subsurface wet services are replaced and comply with industry standards; and that proper surface drainage exists.

ENGLISH ABSTRACT: The importance of and the need for metropolitan planning and government structures in the development of cities have become evident over the last century. Internationally, the approach to metro governance has evolved from informal metro management structures into, for example the more formalised two-tier or single tier systems of London and Toronto. The recent changes in these systems indicate that there is not one system that is universally accepted as the best. South Africa has not escaped the metropolitan development process and the resulting problems that went hand in hand with this. The first form of metropolitan planning in South Africa occurred in 1940, with the inception of the Joint Planning Committees. Later, in 1986 the institution of Regional Services Councils served as the first form of metropolitan governance. In 1995 the first democratic Local Government elections hailed the entry into democratic metropolitan government structures. With the proclamation of six new metropolitan areas South African metropolitan governments adopted the two-tier metropolitan system. Since 1995 South African local government structures have undergone major transformations. Proponents of the current two-tier system failed to anticipate the pressures of Central Government for change to the one tier, megacity or unicity model. Critics of the government's plans argued strongly for the retention of the current two-tier model and for minimal organisational change. The disruption that yet another transformation will cause, is one of the main objections. In the Cape Town and Durban Metropolitan Areas the consensus seems to be that the present two-tier system is working well and that it should be retained. In the case of Johannesburg Metropolitan Area many problems were encountered, especially the inability to redistribute local government income. The consensus there is that a unicity model will work better. Whether the unicity model is the answer to urban sustainability for all metropolitan areas of South Africa, is still a disputed fact.
AFRIKAANSE OPSOMMING: Die belangrikheid van en die behoefte aan metropolitaanse beplannings- en regeringstrukture in die ontwikkeling van stede het oor die afgelope eeu baie ooglopend geword. Die benaderings tot metropolitaanse bestuur in internasionale kringe het beweeg van die meer informele metropolitaanse bestuurstrukture na die meer formele een- of tweevlak stelsels van byvoorbeeld Londen Of Toronto. Die onlangse veranderinge in hierdie stelsels is 'n bewys dat daar nie een stelsel beataan wat universeel as die beste aanvaar word nie. Suid Afrika het nie die proses van metropolitaanse ontwikkeling en die gepaardgaande probleme daarvan vrygespring nie. Die eerste vorm van metropolitaanse beplanning in Suid Afrika was die instelling van die Gesamentlike Beplanningskomitees in 1940. Later in 1986 met die totstandkoming van streekdiensterade was daar vir die eerste keer sprake van 'n vorm van metropolitaanse regering. Met die eerste demokratiese verkiesing van plaaslike regeringsisteme in 1995 is ses tweevlak metropolitaanse egerings in suid Afrika ingestel. Sedert 1995 het plaaslike owerhede in Suid Afrika grootskaalse veranderinge ondergaan. Voorstanders van die huidige tweevlak stelsel het nie daarin geslaag om die druk van Nasionale Regering om te verander na 'n eenvlak, unistad of megastad sisteem, af te weer nie. Kritici van die regering se planne het hewige argumente aangebied vir die behoud van die huidige sisteem asook vir minimale organisatoriese veranderinge. Die hoof beswaar was die grootskaalse ontwrigting wat nog 'n transformasie proses sou meebring. In die Kaapse en Durbanse Metropolitaanse Gebiede is daar konsensus oor die werkbaarheid van die tweevlak stelsel en ook dat dit behoue moet bly. Johannesburg Metropolitaanse Area daarenteen het etlike probleme ondervind, veral met die verdeling van munisipale inkomste. Daar is konsensus dat' n unistad model waarskynlik beter sal werk. Of die unistad model die antwoord is op stedelike volhoubaarheid in alle metropolitaanse gebiede in Suid Afrika, is steeds 'n debatteerbare punt.

The study examines the functioning of municipal councils in ensuring the provision of services to communities in a sustainable manner. Municipalities are at the coalface of service delivery, which is why they are significant in improving the quality of lives of the communities under which they serve. The study is significant as municipalities in the recent past experienced different forms of civil disobedience which could arguably be attributed on the lack of capability by municipalities to respond adequately to the delivery needs for services from communities. Thus, the research stems from the fact that municipalities are charged with the responsibility of providing services to communities in a sustainable manner as mandated by Section 152(1)(b) of the Constitution, 1996. Hence, the failure to deliver will impact the community, especially the indigent, to an extent that the quality of their lives will degenerate. This research investigates the role and functions of municipal councils in making decisions that would have an effect on the provision of services in municipalities in South Africa. Thus, the study has three objectives: • to establish the role that the municipal council plays in ensuring effective and efficient service delivery plans; • to determine the extent to which the municipal council influences the implementation of decisions for effective administration of the delivery of services; and • to develop a framework that enhances the decision-making capability of the municipal council. The research investigates the role of the municipal council in establishing its effect on the administration of a municipality. Thus, this research will answer two research questions: • What role do municipal councils play in ensuring effective and efficient service delivery plans or integrated development plans? To what extent are municipal councils significant role players in terms of influencing the implementation of decisions required for the administration of the delivery of services by municipal officials? The success of a municipality depends on the quality of the decisions made by the municipal council and the administrative capacity of the officials carrying out tasks as mandated by the municipal council. Hence it is argued that the effectiveness of the municipal administration depends on the effectiveness of the municipal council. Through the proposed decisionmaking framework, the coordination of policies and directives that will result in effective and efficient administration in a municipality is simplified. The study employed a qualitative research method, a case study research design and adopted inductive reasoning, i.e. generation of theory, interpretivism, and constructionism as the dispositions of the research. Both primary and secondary sources for data collection are used. In terms of collecting data through the primary sources, non-participant observation will be applied in order to draw conclusions from observing and listening to the activities taking place in municipal council meetings. Secondary sources that are utilised refer to the documented research conducted by previous researchers, i.e. census, Integrated Development Plans, Auditor-General report and studies conducted by municipalities and other stakeholders. Thus, the study makes a contribution to the body of knowledge by proposing a decision formula and a logical framework that is aimed at enhancing the decision-making process of metropolitan municipal councils.

This study explores the challenges related to language policy and planning in the City of Tshwane Metropolitan municipality. The study sets to look at the at the challenges affecting successful implementation by the City of Tshwane Metropolitan Municipality as a state organ charged with local development and service delivery for the communities. In terms of the Municipal Systems Act of 2000 municipalities are expected to respond to the language use and preferences of their local communities by making sure that their language policies are fully implemented. The researcher highlights that in instances where municipalities communicate information they are required to make special provision for the speakers of African languages in the communities that they serve in the languages they best understand. This work looks at various statutory language policy documents in South Africa in particular, that give the task of language policy implementation to municipalities as they are the local extension of the national government. This study also argues that municipalities are critical to implementation of language policy. It further notes that in order for the full social, economic and political transformation to take place in municipalities they have to be transformed linguistically in a radical way whereby all the official languages play a major role in all these spheres than before. This view is held by many scholars and researchers in the areas of language policy and planning. This study highlights that the challenges to successful language planning and policy in the government sectors are due to lack of commitment by the government, language practitioners and planners and increased monolingualism in the municipality. The study further explores the language policy and plan of the City of Tshwane Metropolitan Municipality and the the strategies that can contribute to successful optimization of language resources of the Tshwane Metropolitan Municipality in order to give effect to the use of local languages as contained in policy documents and also establish how the city of Tshwane can better reinforce its strategies to implement this language plan and policy. The main focus area of this research is on the language policy and plan of the City of Tshwane Metropolitan Municipality and assesses whether the language practices in these institutions are reflective of their policy and plan. It is hoped that the study will be able to give policy makers and those tasked with implementation, especially at government municipalities’ strategies for improvement in the functionality and the implementation of their language policies and plans. It is also hoped that recommendations and challenges highlighted by this research will be of a better assistance on how to better reinforce strategies to implement the language plan and policy in the government sectors.

INTRODUCTION: The aim of this study was to determine the characteristics of and factors impacting on the intake of fast-foods by young adults from different socio-economic areas in Gauteng, South Africa. The population for the study (n = 341) included males (n = 180) and females (n = 161) with a mean age of 24.48 years (SD = 3.492). METHODS: A descriptive cross-sectional, observational study was performed using an interviewer-administered, validated questionnaire to elicit characteristics of the studied population (gender, education level, income status and income level), reasons for – and frequency of – fast-food intake, specific food choices at certain categories of fast-food outlets, as well as consumers’ attitude towards health and healthier meal options. Purposive sampling of shopping malls was done to collect data on three weekend days at grocery stores in the shopping complexes. Statistical analysis included: Pearson Chisquare tests, likelihood ratios, linear by linear associations and Cramer’s V and Kendall tau b tests. RESULTS: The studied population consisted primarily of working young adults with at least secondary education. Almost half (n = 103) of the employed participants from all socio-economic groups earned less than R5 000 per month, but spent more than R200 each month on fast-food. The majority of participants consumed take-away meals from two to three times a month to two to three times per week (85.3% (n = 291)). Socio-economic grouping (SEG) and gender were significantly related to fast-food intake (p < 0.01) with a larger proportion of participants (n = 76) in the lower socio-economic grouping (LSEG) showing more frequent use and males consuming fast-food more frequently than females. The most popular fast-foods consumed by participants in descending order were burgers 69.5%, pizza 56.6% and fried chicken 38.4%. A significant difference in the consumption of fried chicken was observed between the different SEGs, with significantly more participants from the LSEG consuming fried chicken 47.0% (p < 0.05). Choice of fast-food outlet concurred with the most popular fast-food choices. Sweetened soft drinks comprised the most popular beverage for more than half of the studied population (n = 191). The main reasons for choosing fast-food were time limitations (58.9%), convenience (58.2%) and taste (52.5%). The majority of participants were concerned about health (93.3%), with almost half of the total sample being always concerned. The majority of participants indicated concern about overweight and obesity (44.3%). Seventy-eight percent of participants indicated that they would choose a healthier option, if available. Television provided the most effective media influence on food choices. CONCLUSION: The findings of the study show a clear discrepancy between fast-food intake and health consciousness, indicating a gap between knowledge and practice. In the light of the spread of the obesity epidemic in South Africa, further research on fast-food consumption in other areas in South Africa and in other age groups (especially children and adolescents) is strongly recommended.

ENGLISH ABSTRACT: The current subsidy system, designed to make South Africa’s public transport more affordable, has instead contributed to a worsening of the existent neglected state of affairs. Although subsidy policies are in place, misdirected allocation renders them mostly ineffective. The implementation of the new integrated public transport systems for metropolitan areas affords an opportunity to adopt a broad spectrum approach and initiate a redesigned and improved subsidy system. The purpose of this study is to assess the South African urban public transport industry with the aim of finding by means of a system-based process a subsidy approach that will overcome the remaining inequalities of the past. This study will consequently evaluate different subsidy theories and determine which one(s) will be best suited to the demands of a specific period. The final objective is to design a product which offers government a systembased process that will help it determine, every few years, whether the subsidy regime being applied at that juncture is still relevant to the requirements of the market and/or what (new) approach is necessary to achieve social and economic wellbeing. Commuter transport in South Africa is currently in a transition phase where new public transport infrastructure is being implemented in the metropolitan cities. The current economic recession (making people’s demand more elastic to prices) present a good time to conduct the system-based process necessary for transition of the public transport system and determine an optimal subsidy approach for the new system. The first step in the system-based process was to determine the scope of work and the overall objectives that should be reached. The main public transport shortcomings are the lack of accessibility to affordable transport for the poor and increasing private transport ownership by the rich, which increases congestion and forms the second step of the systembased process. The third step stated the action plan of strategies on how the objectives could be reached. These three steps also form the basic measurement criteria against which the different subsidy approaches needed to be tested. The fourth step in the system-based process to a better subsidy approach was to evaluate different theoretical subsidy approaches. The review of different subsidy approaches has indicated that some approaches work better than others, but an optimal subsidy system is almost never found.

ENGLISH ABSTRACT: The dissertation firstly outlines the findings of recent studies that have recorded the relationship between transport and economic development. This includes the assessment of a number of economic evaluation techniques that are available to predict the impact of improvements in transport on economic development. An historic overview is provided of the role that transport has played in the development of Cape Town. Due to the fact that the phases of development followed international development trends, it is concluded that development in Cape Town will follow the global trend. A number of economic growth scenarios are developed for Cape Town to assess how the City will be able to cope with the socio-demographic challenges facing it in the next century. The relationship between land price and the economic development potential of land is outlined, as are the factors that determine industrial land price, namely the demand and supply of industrial land. The process of determining the economic value of industrial land is described. This includes the collection and analysis of occupation rent of industrial townships in Cape Town, the calculation of property values and the calculation of the shadow price of land. A procedure of determining accessibility to industrial townships in Cape Town was developed. Firstly, accessibility was defined in broad terms. This was followed by a discussion of each of the elements of accessibility namely proximity, access and mobility in order to understand the factors that may impact on the level of accessibility. Finally, the level of accessibility is quantified in terms of generalised cost. A regression analysis was undertaken to establish a statistical relationship between the economic value of industrial land and accessibility to the industrial townships. The development of a numerical model was based on the regression analyses to forecast changes in industrial land price given a change in accessibility. The model was then tested on a case study. The main conclusions of the study are as follows: (a) The accessibility of industrial land in Cape Town is linked closely to its CSD I Port (it was not possible to separate the CSD and the port), which is typical of a monocentric city structure. (b) There is a positive, significant, quantifiable relationship between accessibility as quantified by means of generalised cost and the economic value of industrial land, which was calculated by means of the shadow price technique. (c) There are a number of conditions that should be met for an increase in local industrial production potential to be translated into an equal amount of economic output.
AFRIKAANSE OPSOMMING: Die proefskrif som eerstens die bevindings van onlangse studies op wat die verwantskap tussen vervoer en ekonomiese ontwikkeling dokumenteer. Dit sluit die taksering van 'n aantal ekonomiese evaluasietegnieke in wat beskikbaar is om die impak van vervoer op ekonomiese ontwikkeling te voorspel. 'n Historiese oorsig word verskaf van die rol wat vervoer gespeel het in die ontwikkeling van Kaapstad. As gevolg van die feit dat die fases van ontwikkeling in die verlede internasionale ontwikkelingstendense gevolg het, word tot die gevolgtrekking gekom dat Kaapstad die globalisasie markera, wat tans internasionaal gestalte kry, sal navolg. 'n Aantal ekonomiese groeiscenarios word vir Kaapstad ontwikkel ten einde te bepaal hoe die stad die sosiodemografiese uitdagings van die volgende eeu sal hanteer. Die verwantskap tussen grondprys en die ekonomiese ontwikkelingspotensiaal van grond word omskryf, asook die faktore wat industriële grondprys bepaal. Die proses van die bepaling van die ekonomiese waarde van industriële grond word beskryf. Dit sluit die insamel en analise van besettingshuurdata van industriële dorpsgebiede, die berekening van eiendomswaarde en die berekening van die skaduprys van grond in. 'n Prosedure is ontwikkel vir die berekening van die toeganklikheid van industriële dorpsgebiede in Kaapstad. Eerstens is toeganklikheid in breë trekke gedefinieër. Dit is gevolg deur 'n bespreking van elk van die elemente van toeganklikheid, naamlik nabyheid, aansluiting en mobiliteit ten einde die faktore wat op die vlak van toeganklikheid mag impakteer te verstaan. Laastens is die vlak van toeganklikheid gekwantifiseer in terme van veralgemeende vervoerkoste. 'n Regressie-analise is onderneem ten einde die statistiese verwantskap tussen die ekonomiese waarde van industriële grond en toeganklikheid na industriële dorpsgebiede te bepaal. Die ontwikkeling van 'n numeriese model is op die regressie-analise gebaseer ten einde veranderinge in industriële grondpryse te voorspel, gegewe 'n verandering in toeganklikheid. Die model is op 'n gevallestudie toegepas. Die vernaamste gevolgtrekkings van die studie is : (a) Die toeganklikheid van industriële grond in Kaapstad is nou gekoppel aan die sentrale sakekern I hawe (dit was nie moontlik om die sentrale sakekern en hawe te skei nie), wat tipies is van n monosentriese staduitleg. (b) Daar is n noemenswaardige positiewe kwantifiseerbare verwantskap tussen toeganklikheid, soos gekwantifiseer in terme van veralgemeende koste, en die ekonomiese waarde van industriële grond wat deur middel van die skaduprystegniek bereken is. (c) Daar is 'n aantal voorwaardes waaraan voldoen moet word alvorens 'n toename in plaaslike industriële produksiepotensiaal tot 'n soortgelyke toename in ekonomiese ontwikelingspotensiaal sal lei.

In recent years growing attention of international and local water research was directed to greywater as a potential water source, as well as its significance as a possible health risk to humans and as a source of pollution. Owing to a general lack of waterborne sewage infrastructure, health risks and pollution associated with greywater generation in informal settlements are of particular concern to municipal managers. However, so far only limited information on the greywater generation, use and disposal in informal settlements is available. Using four different informal settlements in the highly urbanised eastern region of the Ekurhuleni Metropolitan Municipality in Gauteng (also known as East Rand) this study aims to characterise selected aspects of the greywater situation as a first step towards future improvements through appropriate interventions and greywater management. Following consultations with representatives of the local municipality (colleagues of the author) the following four informal settlements with distinctly different greywater appearance were selected as study sites: • Benoni - Harry Gwala • Springs - Gugulethu • Brakpan - Mkhanca • Nigel- Soul City As part of the reconnaissance phase of the study, each site was visited and field observations on infrastructure, habits and other greywater related aspects were made and suitable households for subsequent interviews were identified. In each settlement a total of 25 households were chosen and a representative interviewed using a pre-designed questionnaire comprising eight sections, four sections covering the following aspects: access to and sources of water, general sanitary situation, water use and associated generation as well as disposal of greywater. Interviews were conducted between November 2006 and August 2007 and varied in duration between 20 and 30 minutes per interviewee totalling close to 48 hours. They were either conducted in Zulu or South Sotho, the most widely spoken languages of the interviewed residents. Answers were recorded in English on site. Results were subsequently captured in EXCEL and statistically evaluated. The average volume of greywater generated by the four different water usages, Le. bathing, cleaning, laundry washing and dish washing varies from 35 to 60 /household/day. With each household comprising an average of four people (two children and two adults) this equals a greywater generation rate of approx. 9 to 15 l/person/day and is somewhat lower than reported in comparable studies in South Africa. Owing to the fact that all volume data are estimates, a comparatively large margin of error is to be expected, explaining why in some cases more water was estimated to be used than was actually fetched. Water use volume was found to be influenced by the availability of stand pipes and in one case was supplemented by collected rain water. Generally, however, water was not perceived to be a problematic issue compared to more pressing needs such as housing, unemployment etc. Washing of cloths in all settlements was found to be the single most important source of greywater generation accounting for a third to almost half of all greywater generated. The smallest contribution comes from water used for cleaning (approx. 10%) while bathing and washing dishes accounts for equal proportions of the reminder. Chemical and microbiological analyses of greywater, sampled at selected sites across the four study areas, revealed significant variations in quality between the different sites, without allowing for clear distinctions between the impacts of different brands of detergents such as soaps, washing powder and dish washing liquids. Contrary to literature E-coli contamination was found not be confined to bath and kitchen waste water only, but also appeared in laundry water, frequently exceeding values stipulated in the general standards of waste water or effluent in South Africa This is of particular concerns since some of the greywater is disposed of into stormwater canals and in other non-formal ways, that allow for subsequent exposure of humans to the contaminated waste water. In order to facilitate rapid drainage in some instances respondents created their own greywater disposal infrastructure e.g. by digging open waste water trenches across backyard borders. Regarding potential health risks it is to be noted that at least one respondent reported the use of the water resource (Blesbokspruit) as toilet facility. Apart from the actual findings the study also revealed the importance of an appropriate research design and conduct that addresses the peculiarities of an informal setting. This includes overcoming logistic challenges such as limited accessibility of the study sites during wet seasons owing to flooded and muddy roads, safety and security issues as well as difficulties to conduct indoor interviews owing to a lack of light (no windows, no electricity) leading to low temperatures in winter limiting interview duration. In addition to this socio-cultural aspects and attitudes of respondents have to be taken into account in order to obtain true reflections of facts through interviewing. In this regard it was helpful that the author, as a black female, was familiar with certain customs and perceptions regarding sensitive issues such as use of toilets, connotations of muti (= a traditional medicine that may be included in bathwater as a constituent) etc. Being aware of these peculiarities allowed the author to detect and explain differences between statements obtained from the respondents and her own observations.

Municipal solid waste management systems (MSWMS) comprise of waste generation, segregation at the point of generation, collection, transportation and disposal at the landfill. The municipalities in South Africa were mandated by the constitution of the country to provide a number of basic services including solid waste management to their citizens. A rapid increase in municipal waste volumes is a problem in urban areas resulting in mushrooming illegal dumps. The aims of this study were to evaluate the municipal solid waste management system implemented by City of Tshwane Metropolitan Municipality in Mamelodi East, identify the challenges within the system and explain the practice of illegal dumping by residents of Mamelodi East. This was achieved through a descriptive cross sectional study which was conducted using qualitative data collection methods. The data was collected through interviews with key informants (two municipal officials and one waste removal contractor) and the waste removal process was observed and photographed. The illegal dumps were mapped and photographed and those of high public health concern were identified. A semi structured questionnaire was administered to the residents living closest to identified dump sites. The analysis revealed that the system implemented by City of Tshwane Metropolitan Municipality included regular door to door and communal collection of waste from the residents, transportation of collected waste to Hetherley landfill and disposal. About 21 illegal dumps were identified, mapped and photographed, and nine of them were considered to pose health risk to the residents, especially those living closest to them. It was discovered that these residents were not happy with the illegal dump next to their yards and recommend that the sites be used for beneficial purpose. Shortcomings included a lack of an updated waste management plan; lack of waste minimization strategy including the 3Rs (reduce, reuse and recycle); and lack of public awareness and involvement in waste management issues. No measures are implemented for prevention of illegal dumping and the only control measure was to clean the dump sites periodically. There is a lack of law enforcement and systems overload. The researcher concluded that the MSWMS implemented in the community of Mamelodi East was inadequate. It is recommended that the community should be involved at the planning phase and all mentioned shortcomings be addressed. The waste management legislation including policies and by-laws, need to be enforced.

ENGLISH ABSTRACT: This study considers the possibility of using special management areas at metropolitan level as a measure to control urban sprawl in South Africa, and specifically in the greater Cape Town area. Important issues included in the study are: international and local measures currently and previously used, relevant South African legislation that support urban edge protection, economic and ethical theories regarding urban edge protection, the measures currently implemented in Stellenbosch, an examination of special management areas and recommendations. International attempts in curbing urban sprawl dates back to post-Industrial Revolution Europe (1800s). British and American measures are compared, mostly differing in the level of public support of sustainable development. Local attempts have been limited and have not been implemented at the scale of international measures. Recently developed policies such as the Metropolitan Spatial Development Framework (1996) and the Bioregional Planning Framework (2000) are more directly focussed on sustainable development than previous policies (e.g. guide plans and structure plans) have been. The Metropolitan Spatial Development Framework proposes the demarcation of urban edges in the Cape Metropolitan Region, while the Bioregional Planning Framework is intent on dividing the Western Cape Province into bioregions. The Bioregional Planning Framework originated the use of special management areas to control development in rural (agricultural and natural) areas. The idea of this study is to measure the feasibility of using special management areas at metropolitan level, in conjunction with both the Metropolitan Spatial Development Framework and the Bioregional Planning Framework, to protect the urban edge. This study concludes by disproving its hypothesis: special management areas have limited applicability as a general urban edge control measure at metropolitan level.
AFRIKAANSE OPSOMMING: Hierdie studie oorweeg die moontlike gebruik van spesiale bestuursareas in Suid-Afrika, en spesifiek in die groter Kaapstad gebied as maatreël vir die bekamping van stadskruip. Belangrike kwessies wat in hierdie studie ingesluit word is: internasionale en plaaslike maatreëls wat tans en in die verlede gebruik is om stadsgrense the beskerm, relevante Suid- Afrikaanse wetgewing wat die beskerming van stadsgrense ondersteun, toepaslike ekonomiese en etiese teorieë, maatreëls wat tans deur Stellenbosch geïmplementeer word, 'n ondersoek na spesiale bestuursareas, en voorstelle vir toekomstige beleid. Internasionale pogings om stadskruip te bekamp dateer uit die post-Industriële Revolusie era in Europa (1800s). Britse en Amerikaanse maatreëls is vergelyk. Die mees merkbare verskil tussen dié twee lande lê in die vlak van openbare steun vir volhoubare ontwikkeling. Die omvang van plaaslike pogings was in die verlede beperk tot gids- en struktuurplanne, wat nie veel beskerming aan die rand van die stad gebied het nie. Beleide wat onlangs ontwikkel is (die Metropolitaanse Ruimtelike Ontwikkelingsraamwerk en die Biostreekbeplanningsraamwerk) fokus meer direk op volhoubare ontwikkeling as hul voorgangers. Die Metropolitaanse Ruimtelike Ontwikkelingsraamwerk (1996) stel die afbakening van stadsgrense voor, terwyl die Biostreekbeplanningsraamwerk (2000) voorstel dat die Wes- Kaapse Provinsie in biostreke verdeel word. Die Biostreekbeplanningsraamwerk het oorspronklik die gebruik van spesiale bestuursareas voorgestel om ontwikkeling in landelike (landbou en natuurlike) gebiede te beheer. Die idee van hierdie studie is om die uitvoerbaarheid van die gebruik van spesiale bestuursareas op metropolitaanse vlak, saam met die Metropolitaanse Ruimtelike Ontwikkelingsraamwerk en die Biostreekbeplanningsraamwerk, te bepaal. Hierdie studie sluit af deur die hipotese verkeerd te bewys: spesiale bestuursareas het beperkte toepaslikheid as algemene stadsgrens beheermaatreëlop metropolitaanse vlak.

This chapter will examine deinstitutionalisation in Italy, the United States, and post-apartheid South Africa. In examining the different drivers and outcomes of policies in these areas, similar themes to the UK experience emerge. These include: the role of scandals in the pressure for change, the role of fiscal considerations in the development of policy, an initial period of optimism and the impact of scandals. In Italy, the work of the psychiatrist, Franco Basaglia was seen as a possible blueprint for wider reforms. Basaglia’s work became very influential amongst radicals and the anti-psychiatry movement. The USA was at the forefront of the deinstitutionalisation policy. The links between the closure of psychiatric facilities and the expansion of the use of imprisonment have been most closely examined in this context. Finally, the chapter examines the total policy failure that led to the deaths of one hundred and forty-four patients in Gauteng Province, South Africa in 2014

The teaching of English to non-English speakers in historically disadvantaged areas of South Africa is a difficult task for student teachers. This study was conducted in the township schools at Ekurhuleni North District, in the Gauteng province of South Africa. The purpose of the study was to determine the extent to which students at the University of South Africa (UNISA) used interactive teaching strategies in the teaching of English as a First Additional Language (EFAL). The study also intended to highlight the support provided by UNISA lecturers to these student teachers. The study was grounded in interpretivism with self-determination theory (SDT) informing it. The study was a qualitative descriptive case study with document analysis, observations and semi-structured interviews utilised to collect data. Purposive sampling assisted in selecting six student teachers, of which three were male and three were female. The student teachers were studying in their 3rd and 4th years of the Bachelor of Education degree (B.Ed.), specialising in English. Data collected were categorised into codes and themes. The findings reveal that student teachers only used pictures, charts and flashcards as interactive teaching strategies in teaching EFAL. It was concluded that student teachers were not well-prepared in the use of interactive teaching strategies in the teaching of EFAL and were not adequately supported by the university. It is recommended that UNISA lecturers should regularly visit student teachers during their teaching practice offering support, motivation and advice.

Aim/Purpose: The goal of this study is to advance understanding of ICT utilization by SMMEs by checking access, ability (in terms of technological skills) and usage of ICT among some SMMEs entrepreneurs operating their businesses in an underdeveloped areas to enhance their business activities in order to utilizes the digital opportunities 21st century digital economies present. Background: In today’s world no nation or region is untouched by the forces of globalization and digital economy. One of the key pioneering forces of globalization is the advances of ICT like internet, social networks, etc. In the sphere of business, this pioneering force has also altered the way businesses and organizations communicate and interact with customers and society at large. Such alternation presents obvious opportunities for wealth creation and growth for businesses and organizations that are well-equipped to take advantages of them. But for those that are less-equipped, particularly SMMEs, globalization can easily lead to fore-closures and marginalization. It is a common knowledge that SMMEs entrepreneurs mostly rely on ICT gadgets like mobile phone, Laptops, Tablets to conduct their business activities as many of them don’t have enough capital to set up offices with necessary equipment. Therefore, using various ICT functions/programs on these ICT devices to enhance their business activities are critical to their businesses in the 21st century digital economies. Methodology: Purposeful sampling was used to approach fifty-four SMMEs entrepreneurs operating their businesses in underdeveloped areas locally called Townships in Buffalo City Metropolitan. Microsoft excel was used in the descriptive statistics. Contribution: This research will add to the growing knowledge ICT usage in SMMEs in the 21st century digital economies. Findings: The results indicate that the participating SMMEs entrepreneurs need to be educated, trained and supported in the use of the ICT applicable to enhance their business activities in order for them to take advantages of 21st century digital economies present. Recommendations for Practitioners: The agencies tasked with looking after SMMEs in South Africa needs to consider the lacked of utilisation of ICTs by SMMEs entrepreneurs operating their businesses in underdeveloped areas as one of the barrier to growing of their businesses and take necessary steps to address it. Recommendation for Researchers: Since age and gender have been proven to be key-moderating variables in many technology acceptance models. There is a need to explore in depth whether the factors of gender and age also act as barriers. Impact on Society: The research will assist stakeholders, policy makers and agencies tasked with looking after SMMEs to identify the barriers hindering SMMEs to grow and address them accordingly. Future Research: More work needs to be done to check whether gender, age of the SMMEs entrepreneurs have some effects on their attitude towards the integration of ICT into their business activities.
