Food security is a critical issue that has a prominent impact on human well-being, especially for the vulnerable population who has minimal resilience to the impact of food insecurities. Achieving food security is a continuous challenge that is faced by not only developing countries but also developed countries. Differences in political, economy and social structures contribute to the severity and magnitude of the impact on affected population. This thesis looks at the contribution of indigenous knowledge in achieving food security by analyzing the practices of ume kbubu, or "household granary,"in Timor Tengah Selatan located in Indonesia. This thesis examines the practice of using, filling, and maintaining granaries by analyzing the traditional and cultural values that support ume kbubu and how this practice can support local food security through adaptation and new uses by farmers' groups.
