Green Public Procurement (GPP) is increasingly recognized as a vital tool for advancing sustainable development in Africa. This paper compares GPP frameworks in Nigeria, Kenya, and South Africa, focusing on key sectors such as energy, transportation, construction, and ICT. Using survey data from 287 procurement professionals, policymakers, and sustainability officers, the study analyzes the legal, institutional, and operational aspects of GPP across countries. South Africa leads with a mature, well-coordinated system, while Nigeria and Kenya face challenges related to fragmented implementation and weak monitoring. The research highlights the importance of political will, agency collaboration, supplier development, and international support as drivers of successful GPP. The findings offer practical recommendations to harmonize policy and foster sustainable procurement across Africa.

Logistics Management Practices and Post-Harvest-Loss Among Small-Scale Banana Farmers in Selected Counties in Kenya

Banana production as a food crop component cannot be underestimated. Bananas are currently ranked fourth among foods produced worldwide. The study aimed to investigate the effects of logistics management practices on post-harvest loss among small-scale banana farmers in selected counties in Kenya. The study used a cross-sectional research design. The target populations were small- scale banana farmers from three selected banana-producing counties in Kenya. The study's sampling frame was a list of 14,447 farmers from three selected counties. The researcher stratified the counties and used a table of random numbers to pick farmers. Data were collected using a semi-structured questionnaire. Descriptive and inferential statistics were used to analyze the data in SPSS. The findings reveal a significant negative relationship between logistics management practices and post-harvest losses among small-scale banana farmers (β = -0.536, p = 0.000). The study concludes that effective logistics management can significantly reduce post-harvest losses. The study recommends that small-scale banana farmers focus on efficient transportation methods and consider traditional technologies. County governments need to train banana farmers on best practices for handling bananas to prevent damage during harvest and post-harvest stages.

Currently, there is a debate about the performance of cement manufacturing firms. The main objective of this research study was to determine the moderating effect of collaborative capability on the relationship between supplier integration and performance of cement manufacturing firms in Kenya. The study used a descriptive survey research design, with a target population comprising 450 managers from supply chain sections or departments in cement manufacturing firms registered with the Kenya Association of Manufacturers. The study obtained a sample of 212 respondents using stratified sampling by cement manufacturing firms, followed by proportionate allocation, and then simple random sampling within each stratum. Data were collected using a self-administered questionnaire, piloted with 21 respondents from three Cement manufacturing firms. The research study used both descriptive and inferential statistics to analyze the collected data. Furthermore, bivariate correlation and linear regression analyses were used to test the degree of association (correlations) between supplier integration and firm performance. In addition, hierarchical and stepwise regression analyses were conducted to determine the moderating effect of collaborative capability on the relationship between supplier integration and performance of cement manufacturing firms in Kenya. Based on the results, supplier integration is positively and significantly correlated with the performance of cement manufacturing firms in Kenya. Furthermore, the findings revealed that collaborative capability significantly moderates the relationship between supplier integration and firm performance. Therefore, the recommendations of this research study are that cement manufacturing firms in Kenya should continue to be deliberate in their supplier integration practices and even create collaborative environments to enhance the relationship between supplier integration practices and cement manufacturing firms' performance in Kenya.
