Abstract: This study examined the effect of community-based tourism projects on local community livelihoods in Nyamasheke District, with reference to the Nyungwe Community Guide Project. Specifically, the study attempted to assess the effect of stakeholders’ networks in the Nyungwe Community Guide Project on local community livelihoods in Nyamasheke District. The study was guided by Stakeholder Theory, which explains the importance of relationships, coordination, information sharing, and resource exchange among actors who influence or are affected by a project. A descriptive-correlational research design was adopted using a quantitative approach supported by qualitative information from the study context. The target population comprised 272 respondents, from which a sample size of 162 respondents was determined, while 154 questionnaires were distributed and 142 were returned, giving a questionnaire response rate of 92.2%. Data were collected using structured questionnaires and interviews, and quantitative data were analyzed using descriptive statistics and Pearson correlation analysis; a single-predictor regression interpretation was also developed from the reported bivariate correlation. Findings from the questionnaire showed high agreement that stakeholder networks supported project effectiveness, access to resources,information sharing, community engagement, and local livelihood improvement. Pearson correlation analysis showed a strong positive and statistically significant relationship between stakeholder networks and local community livelihoods (r = .773, p < .001). The study therefore concluded that stronger stakeholder networks were associated with better livelihood outcomes among communities linked to the Nyungwe Community Guide Project. The study recommends strengthening coordination mechanisms, information-sharing channels, resource linkages, and collaborative relationships among project stakeholders so that local communities can access tourism-related opportunities more effectively.
