AbstractDebates around urbanization, infrastructure disruption and the creative class rarely appear alongside each other in research on African cities. This article connects these different narratives, which are currently exerting their influence on the future direction of these cities. The economic value of the creative class is that their work centres on innovation—a quality seen as essential to 'new‐economy' urban growth. Quality of place (that which makes 'New York New York') is said to attract the creative class to certain cities, as lifestyle amenities are valued as much as employment opportunities. Nairobi is an example of an African city currently attracting both Kenyan and expatriate creative class workers, particularly in the information and communication technology (ICT) sector. In this article we take Richard Florida's creative class theory as a departure point to offer insights into why this group chooses to live in Nairobi and to describe Nairobi's quality of place, with a particular focus on infrastructure disruption. The case study reveals that Nairobi's quality of place differs fundamentally from the normative attributes prescribed by creative class theory and, in some instances, it is considered to be highly frustrating and unattractive.

A solar energy technology roadmap has been developed for South Africa. The roadmap lists a number of technological systems that fulfil three requirements from a South African perspective. First, they have clearly been demonstrated or commercialised. Second, a local industry could be stimulated including the potential to export, with associate socio-economic growth; and the other requirements of government can be met in terms of improving energy security and access, and addressing climate change. Third, they have a medium to high R&D intensity, in terms of available capacity and associate resources needed to support the further development of the technological systems. Concentrated Solar Thermal systems feature prominently in the list of technologies. These systems can generate electrical power, then referred to as Concentrating Solar Power systems, typically in the 1 to 100 MW range for on- and off-grid applications. They can also simply produce heat, typically in the 100 to 1000ºC range, primarily for commercial and industrial process applications. This paper discusses the international trends and drivers for these systems to generate power and heat, and then focuses on the specific potential in the South African context. A number of barriers to realizing the potential are discussed and recommendations are made accordingly to stimulate the growth of this industry sector in South Africa.

PurposeAsset management is often one of the last options to maximise cost savings in a competitive global economy due to its intrinsic complexity, especially in many developing countries. Asset management in the process industry must consider the commissioning, operational and end‐of‐life phases of physical assets when commencing a design and implementation project. However, current asset management models show inefficiencies in terms of addressing life cycle costs comprehensively, as well as other aspects of sustainable development. An asset life cycle management (ALCM) model is subsequently proposed for assets in the process industry, which integrates the concepts of generic project management frameworks and systems engineering with operational reliability in order to address these inefficiencies.Design/methodology/approachExperiences within a large petrochemical company in South Africa are used as a case study to demonstrate and discuss the different components of the proposed ALCM model.FindingsOperational reliability and systems engineering are the means to achieve optimum value from physical assets over a facility's lifetime. Thereby, activities are identified that should be completed during each stage of the project life cycle. The application of performance measurements for the operation and support stages is proposed to influence decision making in the process industry.Originality/valueSpecific issues pertaining to the ALCM model are highlighted to ensure optimal practicality and incorporation of the model with other management practices in the process industry.

The economic situation of mining corporations operating in South Africa has in recent years created considerable challenges in staying globally competitive. One reason for this is the increase in average electricity costs from 7% to 20% of total operational expenses since 2007. Forecasts for the next decade predict that this development will continue at similar rates. The reliability of Eskom has also decreased, with self-generation being increasingly considered. In addition, the South African government plans to launch a carbon tax in 2016, which will further add to the costs of current electricity sources. This paper investigates the potential of renewable electricity sources for mining operations in South Africa. It is based on an extensive literature analysis, which was conducted in the form of a conceptual review. The investigation of electricity usage patterns reveals that mining operations commonly have a relatively constant day and night consumption. One of the prerequisites for a suitable source is its ability to supply electricity constantly. Most renewable sources can therefore only be used in hybrid versions, owing to relatively high intermittencies, especially with electricity supply from solar photovoltaic and wind generation. Nevertheless, the levelised costs are substantially lower than diesel generators and are already similar to Eskom tariffs, whilst also lowering carbon emissions. The business case of self-generation is shown to be positive. An on-site project can be realised through a power purchase agreement or through own investments.

In this paper the impacts of biodiesel feedstock production in the Eastern Cape Province of South Africa is assessed through the application of a Partial Equilibrium Model to the Eastern Cape Social Accounting Matrix, using canola production in the Province as an 'external shock'. Six economic indicators were estimated. The results show that investment in biodiesel production in the Eastern Cape will generate, in 2007 terms, an additional GDP of R18.1 million and 410 employment opportunities per annum, R24.3 million per annum over an assumed lifetime of 20 years in capital formation, R2.1 million additional income generated in low income households, increase in government revenue, and a positive balance of payment. These indicators imply that, given the parameters that are accounted for in a Partial Equilibrium Model, every Rand invested in canola projects in the Eastern Cape will, overall, be of socio-economic advantage to the Province. It is envisaged that further applications of such models may lead to a better understanding of the implications of biofuels in the South African economy, and thereby inform decision- and policy-making in terms of the sustainability of biofuels production systems in general.

Development projects that are potentially eligible for Clean Development Mechanism (CDM) funding under the Kyoto Protocol, require final approval from the host countries where the projects are to be implemented. The approval requires an evaluation of the positive contribution of the CDM project to sustainable development in the host country. A prototype set of sustainable development criteria is introduced using an evaluation process conducted in South Africa. Weighting values that reflect societal priorities in South Africa are required for these criteria. The paper shows how judgements of industry decision makers and the expenditure trends of the national government (on environmental sub-criteria) can be used to generate a first approximation of such weighting values. The industry judgements are obtained from an Analytical Hierarch Process (AHP) survey. They reflect the perceptions of the automotive supply chain and process industry only, and not other parts of the South African society. A more comprehensive study is required to determine the political and social acceptability of the AHP approach, which should be initiated and managed by the Designated National Authority (DNA) of South Africa.

AbstractThis paper conveys the experiences of the South African automotive industry as it attempted to implement the ISO 14001 standard. Through a questionnaire‐based survey, small and medium‐sized enterprises (SMEs) as well as larger companies were asked about the key motivations for engaging in environmental change, the benefits accrued and the barriers that prevented them from doing so. This paper analyzes the variation in adoption rates in order to establish different relationships between them. The results reveal substantial differences and some similarities with regard to the hurdles, benefits and motivations behind the implementation of environmental management systems (EMSs) that are hidden behind corporate rhetoric and commitment to sustainability. This paper concludes by prescribing robust recommendations that would set off the pace for government officials to incorporate effective and realistic incentives into future policy to better encourage environmental compliance and improved performance while minimizing costs both to businesses and to the Government.
