The focus of this study is to explore the sustainability practices of SME suppliers as influenced by the stakeholders in the mining SC in Zambia. The study aims to provide the policymakers and senior managers of focal firms by developing a detailed framework that helps in examining the SME environment with regard to sustainability practices and formulate measures to increase their sustainability performance to decision making. This qualitative research used 50 semi-structured interviews in addressing the research objective. Interviews undertaking with cross section of stakeholders and using content analysis, the findings revealed that SMEs engage in sustainable practices when working with mining firms but disengage when working with non-mining firms. The findings further revealed the mechanisms employed by SC members in extending sustainability practices to direct and indirect suppliers (mainly informal SMEs) from focal firms. In so doing, the findings highlighted the role of first-tier suppliers as a bridge between the focal firms and sub-suppliers in disseminating sustainability practices. Besides revealing the drivers and barriers to sustainability, the research revealed the mechanisms for mitigating the barriers in order to increase the volume of SME suppliers adopting sustainable practices. This research has several contributions to both academia and practice. The main contribution to academia is a stakeholder framework, which provides a systematic mechanism of examining the sustainability phenomenon. Thus, presenting a theoretical approach for analysing and understanding sustainability practices of SMEs in a developing country context. The main contribution to practice is the production of tools that support practitioners to analyse and better comprehend the relationships in the SMEs sector and by identifying the key stakeholders that support the SMEs. / Copperbelt University
