Abstract:
This study explored the impact of green procurement practices on supplier relationships and sustainability performance in Morogoro Urban, Tanzania, a secondary city symbolic of Africa's rapid urbanization and informal economy dynamics. While global research shows green procurement's potential to drive sustainable supply chains, its implementation in African urban contexts-particularly where informal sectors dominate-remains understudied. A mixed-methods design combined surveys with businesses and suppliers alongside stakeholder interviews. Findings revealed pronounced disparities: large businesses demonstrated stronger collaboration, trust, and ecological outcomes due to institutional support, financial capacity, and partnerships. In contrast, small and medium enterprises (SMEs) and informal suppliers faced systemic barriers, including pronounced financial constraints, limited awareness of policies, and exclusion from formal support mechanisms. While municipal incentives and NGO programs enabled progress among larger firms, informal actors reported minimal engagement and dissatisfaction with institutional outreach. The study emphasized how structural inequities, informality, and fragmented governance continue uneven sustainability transitions, marginalizing smaller and informal economic actors. Recommendations advocate for context sensitive strategies, including tiered policy frameworks, grassroots awareness campaigns, and inclusive financing models, to bridge gaps between formal and informal sectors. By centering the socio-economic realities of a secondary African city, this research contributes to broader discourses on equitable sustainability, urging approaches that harmonize environmental objectives with the needs of vulnerable urban economies in the Global.
