The Government of Kenya initiated Njaa Marufuku Kenya(NMK) Programme, a multi-sectoral programme under the Ministry of Agriculture, which invested in community food security projects as a way of helping local people improve their own lives and livelihoods. The members are given grants and technical support, with the intention of helping them combat food insecurity and reduce poverty. Community participation has for long been ignored in the development of these interventions leading to failures and non-sustainable Projects; as beneficiaries were not involved from the beginning and therefore they did not own them. To address this shortcoming donors and respective governments have employed a new strategy of partnership building and participation of the community members who are the beneficiaries. This paper explores the assessment of the level of community participation in marketing of Njaa Marufuku Kenya the products and sustainability of their food security projects in Kisumu West County, Kenya. The study established that the coefficient of determination was found to be 0.682 meaning that Community Participation in marketing of NMK products influenced sustainability of NMK food security projects to up to 6.82%.
