    The assessment of sustainable supply chain management practices amongst selected manufacturing firms in Ghana=Ukuhlolwa kwezinqubo zokwenganyelwa ukusimamiswa kwezindlela zokusatshalaliswa kwempahla ezimbonini ezikhiqizayo eGhana ezikhethekile.
    (2022) Nsowah, Johnson.; Phiri, Maxwell Agabu.
    The study investigated whether the design and application of sustainable supply chain management (SSCM) practices in the Ghanaian manufacturing business enhance their financial performance and make them environmentally and socially responsible. The study was guided by six theories: the contingency theory, the resource-based view (RBV), the relational-view theory (RVT), the innovation diffusion theory (IDV), the stakeholder theory and the resource dependence theory (RDT). The study was underpinned by a pragmatist paradigm and followed a mixed-methods methodology, which combined interviews and surveys questionnaires to gather qualitative and quantitative data from a sample of 303 employees of Ghanaian manufacturing firms and 20 individuals who lived nearby. The data analysis findings revealed that relational, instrumental, knowledge and moral factors have a significant and positive direct effect on SSCM practices. Moreover, SSCM practices have a positive and significant effect on the economic, environmental and social performance of manufacturing firms. Barriers to the adoption of SSCM practices were also revealed. The findings led to the recommendation that firms need to use environmentally friendly materials for their products and introduce standardized procedures for recycling and disassembling products. In addition, manufacturing enterprises should collaborate with suppliers to ensure that they also adhere to sustainability standards in their processes and deliver services/products that support sustainability goals. Iqoqa Ucwaningo lwahlola ukuthi ngabe ukwakhiwa nokusetshenziswa kwezinqubo zokwenganyelwa kwezindlela zokusatshalaliswa kwempahla ngendlela ecabangela ingomuso emabhizinisini akhiqizayo eGhana, kuyakuthuthukisa yini ukusebenzisa kwawo izimali, nokuthi kuyenzeka yini ukuthi anakekele imvelo nemiphakathi. Ucwaningo lwalulandela izinjulalwazi eziyisithupha: icontingency theory, iresource-based view (RBV), irelational-view theory (RVT), iinnovation diffusion theory (IDV), i-stakeholder theory neresource dependence theory (RDT). Lolu cwaningo lusekelwe yipharadaymu yokungenzeka lwase lulandela indlelakwenza engxube eyahlanganisa izinhlolovo nemibuzo eyisaveyi lapho kuqoqwa imininingo eyikhwalithethivu neyikhwantithethivu esampuleni labasebenzi abangama-303 bezimboni zaseGhana ezikhiqizayo nabantu abangama-20 abahlala eduze nazo. Imiphumela yohlaziyo lwemininingo yaveza ukuthi izimo eziphathelene nobudlelwane, nezinto ezisetshenziswayo, ulwazi nendlela yokuziphatha kunomthelela obalulekile nomuhle, kulezi zinqubo zokwenganyelwa kwezindlela zokusatshalaliswa kwempahla ngendlela ecabangela ingomuso. Okunye futhi ukuthi lezi zinqubo zinomthelela omuhle nobalulekile kwezomnotho, emvelweni nasekusebenzisaneni kahle nemiphakathi kwezimboni ezikhiqizayo. Kwavela nezithiyo ezikhona mayelana nokwamukelwa kwezinqubo zokwenganyelwa kwezindlela zokusatshalaliswa kwempahla ngendlela ecabangela ingomuso. Imiphumela yaholela ekuthini kuphakanyiswe ukuthi izimboni emikhiqizweni yazo zisebenzise izinto ezingayicekeli phansi indalo nemvelo, nokulandela izindlela ezihlelembekile zempindakusebenzisa nokuhlakaza imikhiqizo. Okunye futhi ukuthi amabhizinisi akhiqizayo kumele asebenzisane nalabo abahlinzeka ngezimpahla ukuze kube nesiqiniseko sokuthi nabo bayazilandela izinqubo ezihlelembekile nezicabangela ingomuso nokuthi bathumela imisebenzi/nemikhiqizo esekela izinhloso ezisimamayo.

    Impacts of supply chain integration on resilience in state-owned logistics enterprises in Namibia.
    (2023) Shooya, Anatolia Tshanyengandje.; Mbhele, Thokozani Patmond.
    The study investigates supply chain integration (SCI) strategy and its impact on supply chain resilience within Namibia's state-owned logistics enterprises, explicitly focusing on the Port of Walvis Bay in the Erongo region. Despite the recognised synergistic effect of SCI on enhancing resilience, its application in Namibia's state-owned logistics enterprises, especially in Port Walvis Bay, requires specific investigation. Motivated by the need to determine SCI's implementation extent and its impact on resilience in these enterprises, the study aims to (a) to establish the impact of internal integration, (b) to determine the effect of supplier integration, (c) to establish customer integration's impact, (d) to determine the impact of information integration, and (e) to examine the relationship between supply chain integration and resilience. The study employed a quantitative questionnaire survey in six logistics industries in Walvis Bay. Data analysis employed structural equation modelling with the partial least squares method. The findings indicate that supply chain integration significantly contributes to resilience and substantially affects state-owned logistics enterprises in the Port of Walvis Bay, Erongo region. However, this relationship is not linear but contingent on the level of supply chain resilience. The study highlights the critical role of supply chain resilience as a mediator between integration and state-owned logistics enterprises, contributing to a better understanding of industry dynamics. This insight is valuable for practitioners and policymakers aiming to enhance the performance and resilience of regional state-owned logistics enterprises.

    Sustainable supply chain towards managing food security of rice in the north central Nigeria.
    (2023) Bello, Adenike Oluyemi.; Mbhele, Thokozani Patmond.
    In a developing nation such as Nigeria, food security which is global agenda that must be achieved by 2030 based on the Sustainable Development Goals is yet to be accomplished. Hence, adoption of sustainable practices across the supply chain of food is fundamental for ensuring food security could be considered. To this end, this study investigates food security in the North central region of Nigeria by examining the strategic role of adoption of sustainable supply chain practices for activities of stakeholders of the rice value chain for availability, affordability, accessibility and competitiveness of rice in the region. The study employed a convergent mixed methods design to provide relevant insights into the stakeholders across the rice value chain. For the qualitative research, 24 rice value chain stakeholders were interviewed (six government representatives, six large-scale rice farmers, and 12 small-scale rice farmers). Quantitative data was collected with questionnaires, which were administered using a stratified sampling technique to 360 small scale Rice farmers association of Nigeria (RIFAN) members. The study from the qualitative data revealed how the available resources of one stakeholder influenced the activity and productivity of another. The regression model revealed that adoption of sustainable practice would impact food security and competitive performance of rice produced from that region. This would improve the profitability and standard of living of rice farmers. The outcome of the quantitative data using Fuzzy Analytical Hierarchical Process-Multi Criteria Decision Making (F-AHP MCDM) weighed the decision-making of stakeholders in line with Triple Bottom Line and the adoption of sustainable practices in activities. The significant implication of the study is that towards food security, adoption of sustainable practices across the rice value chain must be driven by government as a stakeholder. The study recommends the adoption of sustainable practices driven by technology across supply chain of rice and the activities of stakeholders, will improve food security in the region. The study is limited because it could only explore rice stakeholders in the Edu-Patigi local government area of Kwara state, North-central region Nigeria, however, it serves as a foundation for further studies for wider scope or ask specific questions.
