In the case of Garissa County, there are still challenges with regard to governance, such as poor participation processes, poor linkage to legal aid services, and poor accountability processes. To this end, ActionAid International Kenya had been carrying out various interventions aimed at improving governance; however, the impact had not been scientifically tested. The research therefore, aimed to establish the impact that grassroots advocacy and mobilization efforts by ActionAid International Kenya had on good governance practices within Garissa County. The research was anchored on the principles outlined within the Participatory Governance Theory and Accountability Theory. The research was qualitative and descriptive in nature since it sought to establish the impact that grassroots mobilization had on stakeholders within the organizational setup. The research had 300 study targets that comprised staff within ActionAid International Kenya and other stakeholders like county officials and CMD officials. A 177 study sample was randomly picked through stratified sampling techniques. The research made use of scientific questionnaires since it was reliable due to pilot study validation. The quantitative study made use of Pearson Correlation and was carried out utilizing the Windows version 26 SPSS computer application package. The results revealed that grassroots advocacy had a medium positive impact on good governance (Mean = 3.40), and there was a significant correlation (r = 0.507, p < 0.05), especially with regard to raising civic awareness and participation. Legal empowerment had a positive impact (Mean = 3.26), and there was also a significant correlation (r = 0.548, p < 0.05), especially with regard to raising concerns about human rights and justice. Community mobilization had the strongest impact (Mean = 3.33), with significant correlation (r = 0.614, p < 0.05), indicating the process’s emphasis on giving more voice to the people. The conclusion is that ActionAid International Kenya has made significant contributions to the enhancement of good governance in the territory of Garissa County through grassroots advocacy, legal empowerment, and community mobilization.enThesis
