An especially crucial component of every project's execution is project sustainability. The study aims to conduct a thorough assessment of the execution of Kenya's flagship projects and the attainment of national food security in the context of the Galana Kulalu Irrigation project in the counties of Tana River and Kilifi, Kenya. The following four objectives served as the study's guiding principles: to investigate the influence of community involvement on the implementation of the project, to evaluate how stakeholders' engagement can influence the implementation of the project, to examine the impact of completion time on the implementation of the flagship projects in Kenya and to identify the effects of budget and financial management in the implementation of Galana Kulalu Irrigation Project Magarini Sub-County, Kilifi and Tana River Counties. The study adopted a mixed (quantitative and qualitative) method research methodology, with 100 respondents (87) field employees and (3) project managers engaged by the National Irrigation Authority to manage Galana Kulalu food security project and (10) Agricultural Development Corporation (ADC) employees formerly employed by Galana Kulalu project as a target population. A sample size of 81 respondents consisted of randomly selected representatives of all these categories and the response rate of the study was 79%. Data for analysis was gathered through questionnaires and interviews. In order to understand the association between variables with a significance threshold of p=0.05, data collected was examined using descriptive statistics like percentages, frequency distributions, and regression and correlation analysis. Qualitative data was also evaluated using content analysis, and the results were narratively described. To make summarizing easier, the gathered data was presented in tables after being examined using the computer-based Excel program. In summary, from data analysis, it was discovered that the implementation of flagship projects in Kenya and the attainment of national food security are significantly influenced by stakeholder participation, community engagement, completion time, budget, and financial resource management. In this case, the Galana Kulalu Irrigation project. The data analysis gave insightful recommendations for improving food security in Kenya by utilizing contemporary irrigation technology and embracing the four objectives in project successful implementation and sustainability.en-USAgricultural developmentnational development goalsproject performancefood productionrural developmentThesis
