  • Description: Abstract: In contrast to Europe, Asia and South America where geotourism is actively pursued, geotourism activities in South Africa have not to-date been a focus of tourism products. The purpose of this paper is to propose a field methodology that can be used to assess the potential for geotourism development. Existing procedures to establish geotourism site potential are reviewed and a new methodology that accounts for more characteristics than currently found in documented methods is proposed. This consists of three phases: creating a standardised manner of inventorying the sites; standardising field rank scoring for each site by geotourism value, cultural value, ecological sensitivity, accessibility, development requirements, currently available academic literature, and, developing a final multi-site database assisting the South African National Parks to preserve geoheritage sites. Based on previous studies, the Kruger National Park has geoheritage sites that could form the basis for geotourism development: therefore, the methodology was piloted in its northern regions at well-known geoheritage sites. The findings of this study intend to assist the South African National Parks, local community leaders, the private sector (including existing tour operators) and government departments in achieving a national database of geoheritage sites to ultimately be associated with sustainable tourism activity led by local communities.

  • Description: Abstract: This paper studies the adverse environmental impacts of atomic layer deposition (ALD) nano-manufacturing technology on ALD of Al2O3 nano-scale thin films. Numerical simulations with detailed ALD surface reaction mechanism developed based on Density Functional Theory (DFT), and atomic-level calculations are performed to investigate the effects of four process parameters including process temperature, pulse time, purge time, and carrier gas flow rate on ALD film deposition rate, process emissions and wastes. Full-cycle ALD simulations reveal that the depositions of nano-thin-films in ALD are in essence the chemisorption of the gaseous species and the conversion of surface species. Methane emissions are positively proportional to the film deposition process. The studies show that process temperature fundamentally affects the ALD chemical process by changing the energy states of the surface species. Pulse time is directly related to the precursor dosage. Purge time influences the ALD process by changing the gas-surface interaction time, and higher carrier gas flow rate alters the ALD flow field by accelerating the convective heat and mass transfer in ALD process.

  • Description: Abstract: Sustainability is one of the most important challenges of our time. Projects play a pivotal role in the realization of more sustainable business practices and the concept of sustainability has also been linked to project management. However, how managers of projects consider sustainability in their operational daily work is still to be explored. This paper uses Q-methodology to investigate the consideration of sustainability aspects in the decision making processes of project managers. The research question was How are dimensions of sustainability considered in the decision-making processes of project managers in relation to the triple constraint of time, cost and quality? Based on the Q-sort of selected respondents, the study found that the consideration of sustainability principles is underrepresented, compared to the triple constraint criteria. However, the analysis of the individual Q-sorts revealed four distinct perspectives that differ significantly in their consideration of sustainability principles and triple constraint criteria.

  • Description: Abstract: Road transport projects are complex and laden with risks and uncertainties which influence their success or otherwise; even more so, with projects involving the private sector. Private investors decide to proceed with projects based on projections of costs and benefits potentially accruing to a proposed project, which ultimately reflect the success or failure of the project. However, the risks associated with roads delivered through public-private-partnerships (PPP) are grave and if strategies are not put in place to reduce or mitigate the chances of their occurrence, the expected performance of the projects may not be realised. The current paper aims to identify critical feasibility considerations to ensure sustainability of PPP road projects. A thematic content analysis of extant literature and case study illustrations was undertaken. Journal and conference articles were sourced from databases including Academic Search Complete, ASCE Library, Google Scholar, Scopus, Taylor and Francis, Google and Science Direct. Findings revealed that joint decision-making and concessionaire selection procedure and considerations were the most important feasibility factors for PPP road projects sustainability. These factors should be taken cognisance of at the feasibility stage to ensure that mechanisms are put in place in order to realise expected project performance.

  • Description: Abstract: This study aimed at assessing the sustainability of the Rea Vaya Bus Rapid Transit (BRT) system through assessing how the seven elements of service quality affects the commuters’ satisfaction with the service rendered by the Rea Vaya system, and the impact on its sustainability. The rationale for this assessment was to determine whether the system will continue to operate at a low cost for its customers, offer a high quality service that retains commuters and thus, sustaining Rea Vaya’s profitability in the future. A quantitative research method was used for this study, the method allows numerical data collection and enables the study to analyse data. The use of a quantitative data collection method helped in answering the primary and secondary objectives. A questionnaire was used as a means of collecting data handed out to BRT users at selected bus stations on specific routes in Johannesburg. The target population consisted of all users of the Rea Vaya BRT system. Rea Vaya transports an average of 16 000 commuters every day (Rea Vaya, 2009). The sampling unit can be found at five of the fifty-eight Rea Vaya stations currently operational. Data analysis included getting a summary of the mass of data that will be collected and presenting the results to communicate important findings.

  • Description: Abstract: Growing pressures from various players such as governments, non-governmental organizations, and customers have impelled business corporations to address the economic, environmental, and social issues associated with their supply chain activities. Consequently, the concept of sustainability has become a buzzword among scholars and industry practitioners. Although, the concept of sustainability is attaining high level of importance in Europe, America, and Asia due to its ability of ensuring environmental sustainability, in Africa the integration and application of sustainability’s concept is facing several challenges. To date, several studies were conducted to investigate the barriers affecting sustainability practices in mining sector at country’s level. However, an investigative study regarding the barriers of sustainability practices in mining sector of the Southern African Development Community (SADC), which involve fifteen African countries is missing, this paper aims at filling this gap. The data were collected through a quantitative approach. At least 1 423 participants were involved in the survey. The findings revealed that the major barriers blocking the development of Sustainable Supply Chain in mining industry of SADC region include Lack of commitment on environmental deterioration, lack of communication and knowledge sharing, Ineffective monitoring and control system, lack of effective policy and legislation direction, high cost associated with the implementation of SSCM, Poor Supplier Commitment, lack of green practitioners, poor senior managements’ commitment, lack of recycling activities. Lack of Political commitment and support, Lack of managerial support and practical tools, and inadequate individual capacity.

  • Description: Abstract: Sustainable project management is becoming important and the sustainability concepts of people, the planet and profit needs to be incorporated into any type of project. This article focuses on the behavior of the project manager per se and the stimuli patterns that motivate them to adhere to sustainable project management. Three stimuli patterns are used i.e., intrinsically motivated, pragmatic and task driven. To determine which of these patterns influence a project manager, a quantitative pair-wise comparison was used. Twelve statements were used in a pair-wise comparison resulting in a combination of 66 questions. A sample of 101 project managers was analyzed to determine the stimuli patterns. The results indicate that the most prevalent stimulus pattern is the intrinsically motivated pattern with the other two patterns equally important. The results are consistent across gender, age and types of projects as well as industries. It can be concluded that for this study, project managers incorporate sustainability because they feel that it is something they should do. The motivation to consider sustainability is dominated by their behavioral beliefs and the characteristics of the project, or the opinion of others, do not play a large role. This research contributes to the larger body of knowledge with regards to sustainable project management and specifically to the human behavior of project managers. This research addresses the gap that currently exists in current literature where the focus is on the product’s sustainability and sustainable processes.

  • Description: Abstract: The visual aspects of the golf club facilities should create a desire in guests to return. The facilities of any hospitality establishment are referred to as the unrecognised champion that silently welcomes the guest to an area of comfort and safety. But these facilities are equally important to the employees who need to work within the walls, utilising equipment and systems in order to complete their daily tasks. Guests and employees do not look at the hospitality environment in the same way but the importance of maintenance and renovation of these facilities should not be underestimated. The aim of the research was to determine the relationship between golf facilities and sustainability. An explorative, mixed methods research design was used. The results indicated how the facilities contribute to the sustainability of the establishment. The facilities are the first feature of the golf /country club that the member sees. This requires constant upkeep and frequent renovations to attract contemporary members. The study contributes to the literature in the South African hospitality sector and established that there was a positive link between the golf facilities and sustainability.

  • Description: Abstract: Sustainable development has become an important part of the lives and aspect of enterprises operations globally. There is a global trend to enhance sustainable practices in all sectors and most especially the construction sectors, this study discusses the factors that best prevent the implementation of sustainable construction in the Nigeria construction industry. The study further explores and determines the reliability of how sustainability should be measured in the Nigeria construction industry. The study used both primary and secondary data to meet the set objective. The primary data were gathered through the use of a questionnaire distributed to construction professionals, contractors and clients. Indicative findings arising from the study revealed that; Building regulations and financial incentives are found to be the main drivers of sustainable construction in Nigeria and Lack of client demand and awareness and a general perception that adopting sustainable construction is expensive. The research concluded by recommending that government help with building policies to help push construction firms towards sustainable construction and also awareness campaigns should be carried out so that clients would demand and be aware of the benefits of sustainable construction.

  • Description: Abstract: The concept of sustainability is becoming more and more important in the face of dwindling resources and increasing demand. Despite this, there are still many industries and disciplines in which sustainability is not actively addressed. The requirement of meeting current and future needs is not an issue from which IT projects are exempt. Ensuring sustainability requires managing sustainability in all activities. The field of IT and sustainability is one in which literature is appearing, but at a slow pace and this leaves many unanswered questions regarding the state of sustainability in IT projects and the commitment of IT project managers to sustainability. In not knowing what the state of sustainability is, potential shortcomings remain unknown and corrective action cannot be taken. Quantitative research was conducted through the use of a survey in the form of a structured questionnaire. This research was cross-sectional as the focus was to assess the state of sustainability at a single point in time. IT project managers were randomly sampled to get an objective view of how committed they were to sustainability. This research made use of a project management sustainability maturity model to measure the extent to which sustainability is incorporated into IT projects. The findings are that IT project managers are not committed to sustainability. While the economic dimension yielded the best results, they were not ideal, and it is in fact the social and environmental dimensions that require the most attention. This lacking commitment to the social and environmental dimensions is not limited to select aspects within each dimension, as each dimension’s aspects are addressed to a similarly poor extent. This research suggests that sustainability needs to become a focus for IT project managers, but for this to happen, they require the relevant project management sustainability knowledge.

  • Description: Abstract: Sustainability or sustainability development has been a major topic of discussion over the last couple of years. Project management is also a discipline that is starting to focus on sustainability, but the focus is more on the environmental aspect of the project itself. Information systems (IS) projects do not have such a major impact on the environment as construction and engineering projects do. Should project managers that are implementing these ‘soft’ projects be concerned about sustainability? There is currently little or no knowledge about sustainability within the IS domain and whether sustainability is incorporated at all within IS projects. A structured questionnaire was adapted based on previous studies. It was circulated to the project management community within South Africa and a total of 1 099 responses were received. The responses covered all industries and for the purpose of this article, 387 IS projects (35.2% of the total projects) were analysed to determine the level of project management sustainability maturity. The objective of the study was to determine the level of capability regarding sustainability.

  • Description: Abstract: Quality, productivity, and sustainability are three major indicators to evaluate the performance of any manufacturing process. Abrasive water jet machining (AWJM), which is an advanced or nonconventional machining process possess numerous benefits over conventional and other advanced processes for manufacturing of precision engineering components. Material removal rate directly indicates about the process productivity, and often finds contradictory to quality and sustainability. This paper reports the productivity of AWJM process while manufacturing miniature gears of brass. It is a part of experimental investigation conducted to manufacture high quality miniature brass gears using AWJM process. Taguchi L9 orthogonal array based experimental study where a total of nine experiments with two replicates each was conducted to evaluate the effect of AWJM parameters on miniature gear quality, process productivity and sustainability. AWJM parameters were optimized to enhance material removal rate and an optimum value of 18.80 mm3 /min was obtained. Furthermore, AWJM was identified as a superior to conventional machining processes for manufacturing of miniature gears.

Sci. Develop. 8(6) 252-279 , ISSN: 2360-784X , DOI: 10.14662/IJPSD2020.160
  • Description: Abstract: This rural-driven study utilized the liberal political framework to examine the political ecology of water resource governance as a sustainable pathway for decentralization and participatory water supply in rural communities of the Savannah Region. Methods utilized were quantitative, while the ontology and epistemology adopted the post-positivist approaches. Cross-sectional and probability approaches were used to draw a sample of 450 respondents. Self-designed questionnaires were administered while correlation and descriptive statistics were used for analysing the data. With 95% confidence interval and error margin (e) = 0.05, the decision rule for hypotheses test was stated as ‘accept null hypothesis (Ho) if p-value is greater than (˃) the alpha level (α)= 0.05 and do not accept the null hypothesis if the significant level (p-values) are less than or equal to (≤) the critical value (i.e. alpha level, α = 0.05)”. Results showed rural water systems continue to experience incessant cycle of failure, necessitating rehabilitation with resources which should have been used to provide water systems to first time beneficiaries. Training and logistical support, appropriate technologies, human resources, policy enforcement and financial capacities for engendering participatory governance have either been erratic or completely unavailable. Meanwhile, time limitation, family/occupational commitments, finance, social inequalities, knowledge levels and walking distance to decision centres, significantly influenced household’s participation in decision making on water in the communities. Since the “p-values” of the listed variables were generally less than (˂) the alpha level (α = 0.05), the null hypothesis (HO) was ruled out. Decentralized and participatory initiatives are required to transform the Community Water and Sanitation Agency into a professional, non-profit seeking and community-based public utility service-oriented organization. An effective approach for sustaining water delivery is by promoting participatory self-governance and co-management of water systems. This require a shift from the current ineffective Community Management Model (CMM) into a liberal political ecological governance model, with emphasis on synergizing international, national, local government, civil societies and community management efforts and exploration of their comparative advantages. This model should enable the decentralization of financial, human resources, administrative capacities and empowerment of the local communities to participate effectively in public water services delivery.
