Many Kenyan communities rely on nonformal justice systems for fairness alongside established legal frameworks, but face several challenges. There are also concerns that some outcomes of these alternative systems may violate human rights and constitutional provisions. This research aimed to explore the impact of reconciliation, and mediation, on conflict resolution in Isiolo County, grounded in restorative justice theory. A descriptive research design was used, targeting a population of 1,600 individuals, including Borana elders, council members, residents, pastoralists, village elders, and the area chief, with a sample size of 160 (10% of the target population). Random and stratified sampling were applied, and both quantitative and qualitative data were collected through questionnaires and interviews. The data were analyzed using the Statistical Package for Social Sciences (SPSS), with both descriptive and inferential statistics, including correlation and regression analysis. The researcher obtained permits from relevant authorities, such as NACOSTI and the county director of education. Participants were informed about the study's purpose and guaranteed anonymity, privacy, and confidentiality, using pseudonyms when necessary. The findings indicated that alternative justice systems positively impact peace, relationship restoration, and conflict resolution. Community forums and facilitated dialogues helped individuals’ express grievances and collaboratively seek solutions. The study concluded that these systems enhance social cohesion, build trust, and prevent conflict escalation in Isiolo County. Involving community elders and the area chief in the resolution process further strengthens these systems. The study recommends that government agencies collaborate with community organizations and traditional leaders to promote awareness of reconciliation, mediation, and negotiation.
