Abstract

Food security exists when all people at all times have physical, social and economic access to sufficient, safe and nutritious food. Food security is one of the indicators of assessing gross domestic Product (GDP), impacts on human well-being outcomes and National security; it depends on food availability, access, utilization and stability. Sustainability foods systems are affected by factors which include price volatility, climate change, food losses and waste. The term “Sustainable food” has been used as a way to combine the concepts of food security and sustainability. Both food security and sustainability depend upon the post-harvest technology for their stability. This paper seeks to illuminate the potential of review of literatures on climate change, food security, sustainability and post-harvest Technology. Relationship between food systems, and food security were examined, while the concept of post-harvest technology and roles in sustainable food production for food security was addressed. Interrelationships between food security, sustainability and Post-harvest Technology were enumerated.
