    Abstract: The purpose of this paper is to examine the Tanzanian practitioner’s readiness assessment for public–private partnership (PPP) adoption. This study is important as the readiness assessment enables the stakeholders to assess their capability and current status quo to implement new ideas such as PPPs. Design/methodology/approach Underpinned by the theoretical lenses of innovation diffusion theory (IDT), this research undertakes semi-structured interviews with PPP practitioners within the Tanzanian affordable housing sector. The content analysis was used for the data as collected. Findings “Lack of awareness and usage of PPPs framework models during the feasibility and subsequent implementation process”, “Limited knowledge and skills required for PPP practitioners”, “Poor capacity building”, “Lack of engagement of experts during the viability and assessment process” and “Poor selection process of private partners giving rising to unsolicited proposals” are the main PPP features influencing the readiness process and fostering of innovation. Practical implications The identification of the readiness approaches would support PPP policymakers and stakeholders with the government mechanisms for identifying the key areas needed to be addressed to improve the PPP implementation performance. Originality/value Outputs of this study provide insights on how to foster a better understanding of the readiness assessment strategies and approaches for successfully implementing PPP in affordable housing projects.

    Abstract: The purpose of this paper is to identify the critical success factors (CSFs) and key areas for improvement for public–private partnerships (PPP) in affordable housing schemes (AHS) projects, using Tanzania as a case study. Design/methodology/approach Semi-structured interviews were conducted with 10 public and private sector practitioners in Tanzania. The collected data and the interview transcripts were analysed using the standard qualitative analysis technique of content analysis. Findings The findings show the six most important CSFs as: a dedicated team of professionals to oversee the PPP projects, official and unofficial site visits and inspection, government support and guarantees, undertaking checks and balance from the design stage to construction stage, scrutiny of PPP project proposal and trust and integrity. The mapping of the CSFs across the PPP project lifecycle highlighted a higher incidence across the following phases: building ( n = 11), preparation ( n = 10) and operational ( n = 9). Practical implications The identification of these CSFs would support PPP practitioners in successfully implementing PPP in AHS; besides, there is potential for their inclusion in the future development of the affordable housing PPP conceptual framework. Therefore, based on the identified CSFs, both the government and policy makers could use the findings as the basis for re-examining the existing PPP policy and regulations and reflecting on the existing situation with a view to improving the delivery of future PPP projects. Originality/value This paper provides the first empirical study by applying direct content analysis to identify and understand the CSFs and key areas for improvement for PPPs in AHS within the Tanzanian housing sector. This is rather an under researched subject around CSFs for PPPs from developing countries such as Tanzania.

    Abstract: The purpose of this paper is twofold: first, to identify and rank the challenges influencing the delivery of the housing public-private partnership (HPPP) in Tanzania; and second, to suggest solutions in the form of a conceptual public-private partnership (PPP) framework model that will address the identified challenges and boost the chances of success. Design/methodology/approach Using a convergent parallel (concurrent) mixed method approach, data were collected from 28 stakeholders involved with HPPP projects in Tanzania using a hand-delivered and e-mail survey and 13 semi-structured interviews with public and private sector respondents. The quantitative data included subjecting the 19 challenges as identified from the literature to parametric tests such as one-sample t -tests and descriptive statistics tests such as measures of central tendencies and frequency analysis through Statistical Package for Social Sciences (SPSS 22.0). Qualitative data employed content analysis. The research was further underpinned by a number of theoretical perspectives such as Gidden’s structuration theory, contingency theory, relational and equity theory. Findings The top five ranked challenges influencing the delivery of HPPP were “inadequate PPP skills and knowledge”; “poor contracting and tendering documents”; “inadequate project management”; “inadequate legal framework”; and “misinformation on financial capacity of private partners”. The least six ranked and most significant challenges based on the one-sample (single) t -tests were as follows: “Poor risk allocation”; “inexperienced private partner”; “unequal qualification and contributions of expertise”; “poor enabling environment to attract competent partners”; “inadequate mechanisms for recovery of private investors’ capital”; and “high costs in procuring PPP projects”. The qualitative study further confirmed the challenges and cited the reason for the failure of joint venture projects as the lack of motivation for undertaking similar PPP projects. Despite the increased awareness of PPP projects and associated marginal benefits, the main impediment to the uptake and delivery of PPP housing projects remained the lack of skills and expertise. Research limitations/implications The proposed framework model is not yet tested, but since this paper is part of the ongoing research, the next stage involves the testing and validation of the model. Future studies could test the applicability of the proposed framework in other HPPP projects in Tanzania, and in other similar developing countries. Second, the validated framework can contribute towards addressing similar challenges as well as providing guidance. The proposed framework model is not yet tested, but since this paper is part of the ongoing research, the next stage involves the testing and validation of the model. Furthermore, recommendation for future research is to test the alignment of the identified challenges to the proposed remedial solutions across the five phases within the proposed PPP framework with a number of case studies. Practical implications The identified challenges were used to form the basis of the framework presented in this paper. Furthermore, these provide useful information, thus leading to increased awareness to enable successful delivery of HPPP in Tanzania. Similarly, both the government and policy makers could use the findings as the basis for re-examining the existing PPP policy and regulations, and reflecting on the existing situation with a view to improving the delivery of future HPPP projects. Originality/value The empirical study is among the first that identifies and ranks the challenges of PPP for housing projects delivery within the Tanzanian context. The identification of the challenges enabled their ranking, resulting in the mapping out of the most critical challenges. Furthermore, using the Gidden’s structuration theory, the study illustrates how institution mechanisms (structures) address these delivery challenges, thus influencing the implementation of HPPP in Tanzania, and how individual stakeholders (human agents or agency) are able to make choices (advocated solutions) in dealing with the challenges. More so, these constraints (challenges) as identified and viewed through the contingency and equity theoretical lenses form the foundation for developing the PPP conceptual framework. The proposed framework would thus serve as a mechanism for providing practical solutions as well as reducing the level of severity of the identified challenges.

    Abstract: Implementation of public–private partnerships (PPPs) in African projects is inundated with a number of capacity building challenges which affects growth and project performance. Further, there is paucity of empirical studies on the strategies for overcoming these challenges. Therefore, this research addresses that knowledge gap by examining the human capacity building (HCB) strategies for improving PPP implementation in construction projects in developing countries, with a focus on Tanzania. Design/methodology/approach HCB strategies identified from the scoping review were administered to 81 handpicked Tanzanian practitioners attending PPP training course. To examine the differences in the perception of the identified HCB strategies, and the relationships between different pairs of the HCB strategies, the data were subjected descriptive statistics, parametric tests, Kendall’s concordance and Pearson correlational analysis, including group wise correlation analysis. Findings Based on the overall sample, “Engagement of stakeholders on capacity development”, “Organization of PPP seminars and training” and “Introduction of in-house training to Public institutions expected to undertake PPP projects” are the top ranked HCB strategies. “Development of study tours to stakeholders involved in PPP projects” is the least ranked. Significant differences between the sub-groups of “no PPP experience” and “some PPP experience” were evident for “Invitation of International experts to share experiences” and “Sharing of responsibilities” HCB strategies. The “no PPP experience” group rated both strategies higher than those with “some PPP experience”. Practical implications The identified HCB strategies can be used as a “road map” for the development of appropriate engagement strategies with various stakeholders for the successful implementation of PPP thereby, enhancing the performance of the construction firms. Originality/value Eight strategies have been identified from the literature and tested for the Tanzanian context. The uniqueness of Tanzanian PPP implementation context arising from varying cultural, organizational, political and economic conditions differentiates the priority of HCB strategies when compared to other contexts where these strategies were investigated. This is germane to the PPP research.

    Use of anti-gSG6-P1 IgG as a serological biomarker to assess temporal exposure to Anopheles’ mosquito bites in Lower Moshi
    Public Library of Science (PLoS) ; 2021

    Abstract: Malaria prevalence in the highlands of Northern Tanzania is currently below 1% making this an elimination prone setting. As climate changes may facilitate increasing distribution of Anopheles mosquitoes in such settings, there is a need to monitor changes in risks of exposure to ensure that established control tools meet the required needs. This study explored the use of human antibodies against gambiae salivary gland protein 6 peptide 1 (gSG6-P1) as a biomarker of Anopheles exposure and assessed temporal exposure to mosquito bites in populations living in Lower Moshi, Northern Tanzania. Methods Three cross-sectional surveys were conducted in 2019: during the dry season in March, at the end of the rainy season in June and during the dry season in September. Blood samples were collected from enrolled participants and analysed for the presence of anti-gSG6-P1 IgG. Mosquitoes were sampled from 10% of the participants’ households, quantified and identified to species level. Possible associations between gSG6-P1 seroprevalence and participants’ characteristics were determined. Results The total number of Anopheles mosquitoes collected was highest during the rainy season (n = 1364) when compared to the two dry seasons (n = 360 and n = 1075, respectively). The gSG6-P1 seroprevalence increased from 18.8% during the dry season to 25.0% during the rainy season (χ 2 = 2.66; p = 0.103) followed by a significant decline to 11.0% during the next dry season (χ 2 = 12.56; p = 0.001). The largest number of mosquitoes were collected in one village (Oria), but the seroprevalence was significantly lower among the residents as compared to the rest of the villages ( p = 0.039), explained by Oria having the highest number of participants owning and using bed nets. Both individual and household gSG6-P1 IgG levels had no correlation with numbers of Anopheles mosquitoes collected. Conclusion Anti-gSG6-P1 IgG is a potential tool in detecting and distinguishing temporal and spatial variations in exposure to Anopheles mosquito bites in settings of extremely low malaria transmission where entomological tools may be obsolete. However studies with larger sample size and extensive mosquito sampling are warranted to further explore the association between this serological marker and abundance of Anopheles mosquito.

    Abstract: While governments remain accountable for the delivery of infrastructure services, given the paucity of public resources, studies have recommended the use of private sector finance (PSF) as an alternative approach to delivering sustainable infrastructure both in developed and developing economies. Despite the recommendation, there has been very little use of PSF in delivering public projects, particularly in sub-Saharan Africa. Therefore, this study explores the constraining factors for the use of PSF in the delivery of public infrastructure in Tanzania and proposes recommendations. A total of 10 semi-structured interviews were conducted with different stakeholders delivering public infrastructure services. Interviewees were purposefully selected. Data were analyzed through conceptual content analysis. The findings reveal that the top five constraining factors were inadequate knowledge and skills, lack of policy to support or suffice PSF, bureaucracy or delays of approvals, lack of proper models for PSF, and lack of skilled people or existence of a big national skill gap. Thus, the identified constraints provided useful insights and were used as a road map for suggesting appropriate solutions to enhance the use of PSF. Furthermore, this is the first study to empirically explore the constraining factors for PSF in delivering infrastructure projects in the Tanzanian context.
