Barriers to sustainable procurement in higher learning institutions construction projects in the Dar es Salaam Region

Abstract

The study aimed to identify the obstacles preventing higher learning institutions in the Dar es Salaam region from adopting sustainable procurement. In particular, the study sought to ascertain how the legal framework, supplier awareness, staff knowledge, and top management support affected sustainable procurement in the construction projects of higher learning institutions in the Dar es Salaam region. 156 employees who worked as estate officers and procurement specialists made up the study's sample, whereby the Yamane (1967) Formula was used to determine the study's sample size, which was 112 participants. However, only 101 questionnaires were collected, filled out, and returned for analysis. The data were collected using a closed-ended questionnaire using the drop-and-pick method. The data were analyzed using descriptive statistics, where the mean and standard deviation were calculated. At the same time, inferential analysis was done by using multiple linear regression analysis after testing the reliability and validity of the data and the assumptions of multiple regression analysis, including normality, linearity, homoscedasticity, and multicollinearity. The research was carried out using IBM SPSS version 26. According to the study's findings, all four tested variables, supplier awareness, management support, legal framework, and staff knowledge, have a significant positive relationship with sustainable procurement. Management in higher learning institutions should consider these variables to ensure sustainable procurement within their organization.
