Humanitarian supply chain disaster response is core to alleviating communities economically, socially and in the environmental dimension. Stakeholders including donors, governmental and non-governmental organization, and supply aid beneficiaries in the past decade have witnessed a transformation in the humanitarian sector, despite the increased frequency and magnitude of disasters. These have been evident through the increased scholarly works together with collaboration of international agencies to respond to the needs and develop the sub-Saharan Africa region. Humanitarian supply chain sustainability, therefore, is at the forefront of effective and efficient disaster response. Studies done on impact of sustainable supply chain measures in Kenya have put the humanitarian organizations under strict scrutiny for accountability of donor aid and need for improved performance. These situations formed the foundation of the research study.
