  • Description: Abstract: In most developing countries, the huge amount of unmanaged municipal solid wastes and the inefficiency of the current waste management system has resulted in an unprecedented effect on human health and the quality of the environment. The drive towards sustainability in solid waste management in South Africa has led to the promulgation of several legislations and policies directed towards increased efficiency of solid waste management strategies. However, despite the progress in South Africa’s waste management systems over the years, it is still being constantly faced with some challenges and shortcomings. To achieve sustainable development through the transition from a linear economic model to a circular economy, there is a need to revamp the waste management sector. This study presents a survey of the key physical elements of integrated waste management in South Africa. The study further discusses the challenges with major emphasis on the future directions of integrated waste management. Waste management decisions are data-driven decisions. This study identifies the lack of accurate and reliable waste-related data as one of the major factors that impede the fast-track growth towards sustainable waste management in South Africa. A data-mining approach that emphasizes intelligent modeling of waste management systems is recommended to support the national waste database which will aid waste management decisions and optimizes waste management facilities and investments. Sustainability in waste management in South Africa requires a multi-sector intervention and involvement to stimulate sustainable development in waste management.

  • Description: Abstract: The drastic pursuit of economic, urbanized and globalized growth in recent decades have impacted severely on the natural ecosystem and available resources. The insistent climate change is further sustained by enormous food and energy production wastages. This also accounts for the increased tension on water supply and organic practices as consequences of an upset ecosystem; leading to unstable temperature changes, changes to normal weather patterns, floods and drought, melting glaciers and rising sea heads- all to which potentially affects the sustenance of man and the environment. As such, synergizing the food-energy-water (FEW) scarce resources and understanding their potential interactive merits as against their isolated short lived advantages have become an area of interest in recent years. This has driven the discuss herein towards the sustainable benefits of knotting the FEW scarce resources, as all three elements must be unified for ensured beneficial outcomes. The paper also highlighted the FEW interactive challenges and pathways of resource conservation particularly, in the dire need for food security in present time. The paper therefore holds a general discuss that posits the interactive link between the limited FEW resources as a platform towards sustainable conservative benefits of all three elements to man and the environment.

  • Description: Abstract: This study employed the post-positivist epistemology and the cross-sectional survey to examine the factors influencing the sustainability of communities drinking water and local development projects in the Bole, West and Central Gonja Districts of the Savannah Region, Ghana. Proportionate, systematic and simple random techniques were utilised to sample 450 respondents, composed of 392 household heads and 58 officials. Data was collected, utilising self-designed and semi-structured face-to-face interviews and questionnaires. Correlation and regressions were generated to determine relationships between the variables. Results showed community participation (r= 0.576, p-value = 0.019), finance (r = 0.517, p-value = 0.006), sense of ownership (r = 0.573, p-value = 0.012), labour support (r = 0.474, p-value = 0.015), education (r = 0.469, p-value = 0.021), technology (r = - 0.436, p-value = 0.018), maintenance (r = -0.503, p-value = 0.029), water pollution (r = - 0.389, p-value =0.041) and transparency (r = - 0.250, p-value = 0.015), were significantly associated with water projects sustainability. 69.7 percent of variabilities were collectively explained by the independent variables. Since p-values were < α = 0.05, the null hypothesis (Ho) was ruled out in favour of the alternative hypothesis. With strong participation, funding, local ownership, labour, and citizen empowerment, coupled with improved facility maintenance, appropriate technologies, pollution control and good eco-governance, there is almost irresistible likelihood for water and development projects to be sustainable. Depoliticising water, democratisation and eco-friendly strategies are necessary preconditions for an inclusive, self-governing and ecologically responsible citizenship needed for sustainability of water projects at the lowest level of development.

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.

  • 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: Ph.D. , Definitions of sustainable development can be grouped according to their ideological orientation and economic paradigm in which they are placed: neoclassical; social and ecological modernisation of neoclassical; and radical. The view of sustainable development predominant in the mining sector aligns with the dominant neoclassical economic paradigm. It is revealed specifically through the system of metrics used, the most obvious of which is profit, shareholder value, and growth. The idea of sustainability is understood in mining as the need to respond to increasing regulation by adding two extra dimensions to the economic one – social and environmental. This is abbreviated as the triple bottom line, or weak sustainability. In the exercise of process stewardship, mines tend to follow global responsibility guidelines formulated for the sector, but product stewardship is of secondary importance. Narrow definitions of sustainability fail to take into account the biosphere as a complex adaptive system. In this study there is a discussion about an innovative collaborative sustainability model to be developed in a new industrial sector. That sector would operate beyond mining, while at the same time using mining waste residues feedstock as its inputs. The landscape in which the new sector would be located would be the current neoclassical one, but the model has been formulated as a tool to move towards a broader conception of sustainability. As a means of clarifying the fuzzy boundaries between the various entities and components of the complex adaptive system of the biosphere, for the purposes of discussion, the biosphere has been divided into seven separate schematic dimensions (after Gell-Mann, 1994: 345-366). These are ideological, institutional, economic, social, demographic, informational and technological. Six research and development projects, carried out over seven years (2002 to 2009) in a research and development group of a trans-national mining corporation, were directed by the author. These projects, in the fields of improved air quality and of minimisation of mining waste residues, formed the basis for conceptualising a new collaborative sustainability model. The projects, when placed in the context of seven dimensions of the biosphere and as examples of sustainable development, reveal themselves as falling far short of attaining sustainability goals. What a reductionist definition of sustainability used in the mining industry means is that the industry is slow at anticipating needs of communities after a mine closes, or after organisational restructuring and downsizing in the trans-national corporation has happened, or in dealing with the influx of people into the area who come to improve their economic/political opportunities. The implementation of sustainability principles in mines is directed by global protocols, directives and regulatory obligations, and is driven by the market economy.

  • Description: Abstract: Purpose - The procurement strategy challenges influencing the development of sustainable smart housing requires a holistic system approach that models the relationships between procurement strategies and sustainable smart housing development approach. This considers the use of technology partnering to ensure value for money. The purpose of the paper is to assess the mediation effect of the technology partnership on procurement strategy influencing sustainable smart housing development. Design/Methodology/Approach - This study used a quantitative approach and primary data were collected via a structured questionnaire. In total, 500 survey questionnaires were administered to project managers in the Nigerian construction industry and a stratified proportionate random sampling method was used for the selection of respondents. Findings - The results indicated that the procurement strategy influenced sustainable smart housing development in Nigeria, and the technology partnership mediates the relationship between procurement strategy and sustainable smart housing development. Research limitations/implications - This quantitative study is based on the perception of construction project managers in Nigeria. The findings serve as an awareness to the government and other stakeholders in the construction industry on the development of sustainable smart housing in Nigeria. Managerial implications – The study suggests that technology partnership reduces the effect of procurement strategy factors and hence improves development of sustainable mass smart housing infrastructure for the growing population. Practical implications – The study establishes that technology partnership mediates the relationship between procurement strategy factors and sustainable smart housing development through enhancement of smart housing development and serves as awareness to stakeholders on the factors influencing smart housing development in Nigeria. Originality/Value – Mediation roles of technology partnership minimizes procurement strategy challenges and enhances sustainable smart housing development.

  • 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.

  • 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: 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: A key requirement for listing on the Johannesburg Securities Exchange (JSE) Socially Responsible Investment (SRI) index is the publication, by companies, of annual sustainability reports in line with the Global Reporting Initiative (GRI) guidelines that require stakeholders to be included in defining the content of such reports. Despite this requirement, stakeholders appear not to be integrally involved in the process. The primary objective of the study was to determine whether the contents of sustainability reports of the mining companies listed on the JSE SRI index are based on the outcome of robust stakeholder engagement processes undertaken specifically for the purpose of preparing these reports. Against a backdrop of the GRI requirements, a quantitative evaluation was undertaken of recent sustainability reports of 11 South African mining companies. These reports were also qualitatively assessed against the corporate social responsibility (CSR) Journey Model proposed by Mirvis and Googins (2006). The two assessment scores for each mining company were integrated and the companies were plotted according to a CSR journey that encompasses degrees of stakeholder involvement. The findings highlight that while the companies adhere to the quantitative GRI stakeholder engagement requirements, the contents of the sustainability reports have not been specifically informed by stakeholders. Companies also appear to be in the early stages of the CSR journey. Recommendations include advising mining companies to utilise existing stakeholder engagement platforms to advance stakeholder inclusion in sustainability reporting and for mining companies to engage in developing the business case for CSR, which could promote greater stakeholder involvement.

  • 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: 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: Hydro energy still remains the highest RE contributor to electricity generation globally, nevertheless, trends in solar and wind energy has shown increasing investment in RE. Though a decline in investment was observed between 2012 and 2013, yet investment in RE exceeded that of non-RE in the excess of $80 billion dollar. In 2014, investment increased by 16%. As developed countries get saturated with RE technologies, developing countries are now the focus for investment. Wistfully, path dependency problem, lack of adequate infrastructure and policy framework have been highlighted as the major barrier to RE deployment in developing countries. Also, lack of harmonised government agency for RE implementation, incentives and educational gap are the institutional and social barriers. Energy Storage (ES) is being promoted as the “game changer” with capability of smoothening the variability associated with the two RE technologies, wind and solar, with the highest deployment rate. Recent developments are indicative of cost reduction for ES. This paper therefore presents a concise and holistic review of renewable energy (RE) technologies for electricity generation and assess the roles of ES in mitigating intermittency associated with their generation profile.
