Hydropower projects are vital for Rwanda’s economic growth, contributing to the national GDP and accounting for 48% of the country’s installed power capacity. However, these projects face significant environmental risks, including pollution, sedimentation, fluctuating water volumes, and natural disasters such as floods and landslides, which threaten operational efficiency and long-term sustainability. This study aimed to examine the influence of environmental risk factors, specifically pollution risk, sedimentation risk, volume risk, and natural disaster risk, on the performance of hydropower projects in Rwanda, with a focus on Rwaza Hydropower Project in Musanze District. The study is grounded in Stakeholder Theory and Risk Society Theory and adopted descriptive and correlational research designs. The target population consisted of 112 participants, including project managers, plant managers, operators, regulators, and other relevant stakeholders. The study highlights the significant negative influence of pollution, sedimentation, volume fluctuations, and natural disaster risks on the performance of hydropower projects in Rwanda. It is recommended that project managers strengthen environmental management, implement effective sediment and water volume control measures, enhance disaster preparedness, and involve local communities to sustain project performance. Future research could examine the economic impacts of environmental risks, the effectiveness of mitigation strategies, climate change effects, and community participation in improving hydropower sustainability.      

This study examined the influence of implementation interventions on the success of education infrastructure projects in Rwanda, using the China-Aided Expansion Project of IPRC Musanze as a case study. The study was grounded in the recognition that project success is not solely dependent on the availability of financial resources but is largely influenced by the effectiveness of implementation strategies throughout the project lifecycle. Specifically, the study assessed the effect of materials and resource management, financial management, technology adoption, and human expertise and skills development on project success. The study was guided by Implementation Theory and the Project Success Model and adopted both descriptive and correlational research designs. The target population comprised 123 employees of IPRC Musanze at the time of project implementation, including three who were assigned to supervise the project on behalf of the beneficiary institution, as well as 1,243 students who were enrolled during the same period. This resulted in a total population of 1,366 respondents. A mixed sampling approach was employed, whereby a census technique was applied to the employee category, while simple random sampling was used for the student category. Data were collected using questionnaires, interviews, and document review to ensure triangulation and enhance the validity of findings.
