This study investigates the impact of public procurement procedures on the efficacy of public projects within Zambia's Ministry of Infrastructure, Housing and Urban Development (MIHUD) and the Ministry of Local Government and Rural Development (MLGRD).  Inefficient procurement methods, characterised by delays, cost overruns, and inferior project quality, have impeded the successful execution of public projects, especially in infrastructure and rural development.  The research is to evaluate the impact of Supplier Qualification Screening (SQS), Competitive Bidding (CB), and Supplier Evaluation (SE) on project performance.  A quantitative research methodology was utilised, employing a survey-based descriptive design to gather data from 120 procurement experts and project managers within the designated ministries.  Structural Equation Modelling (SEM) was employed to examine the correlations between procurement methods and project outcomes.  The results demonstrate that SQS and CB enhance project performance by facilitating timely delivery and cost effectiveness.  Nonetheless, SE exerted a detrimental impact, indicating that too rigorous evaluation processes may result in delays and impede project accomplishment.  Hypothesis testing validated these findings, corroborating the alternative hypotheses for SQS and CB, however SE demonstrated an inverse correlation with project outcomes.  The report advocates for the fortification of regulatory frameworks, the augmentation of capacity-building programs, the rectification of bureaucratic inefficiencies, and the encouragement of e-procurement platform usage to enhance procurement efficiency.  A review of supplier evaluation procedures is essential to avert needless delays in project execution.  The study's results have substantial implications for procurement reforms and efficiency enhancements in Zambia.  Improving openness, accountability, and stakeholder collaboration in procurement procedures can result in superior project outcomes, fostering national infrastructure development and socio-economic advancement, especially in rural regions.  Enhancing procurement policies and using digital solutions will be crucial in developing a more efficient and accountable public procurement system.

This research examines the critical role of supplier collaboration in advancing sustainable procurement practices within Temeke District’s Blue Economy a coastal zone in Tanzania where marine resources underpin livelihoods yet face escalating environmental pressures. Despite national policies promoting sustainable ocean governance, implementation gaps persist due to fragmented regulations, power imbalances, and the marginalization of informal suppliers. This study addresses an underexplored link: how collaborative relationships between buyers and suppliers enable or constrain sustainability outcomes in complex, resource-dependent contexts. Adopting a mixed methods approach, the research engaged diverse stakeholders across public, private, and community spheres. Findings reveal that transactional procurement paradigms dominate, stifling innovation and ecological stewardship. Trust deficits and restrictive contractual frameworks inhibit meaningful partnerships, while pervasive informality excludes suppliers with invaluable place-based knowledge. Nevertheless, intermediary actors, such as NGOs and community leaders emerge as vital bridges, fostering adaptive solutions through locally embedded dialogue. The study identifies key barriers, including conflicting sectoral policies, financial exclusion, and gendered occupational segregation, which limit inclusive participation. Conversely, enablers like co-designed "Sustainability Compacts" and intergenerational knowledge exchange offer pathways for reform. Recommendations prioritize integrated governance, supplier empowerment funds, and gender-responsive platforms to reconfigure collaboration as a catalyst for equity and resilience. By centering Temeke’s socio-ecological realities, this research contributes a framework for transforming procurement from a compliance exercise into a regenerative force. It argues that effective Blue Economy transitions require redistributing agency to frontline suppliers not as contractors, but as custodians of coastal futures.
