This book looks at food security from a socio-economic perspective. It offers a detailed and systematic examination of food security from its historical backgrounds, concepts and measurements, to the determinants and approaches to achieve food security. The book also introduces the key challenges and root causes of food insecurity.

Through country-specific cases, the book highlights instances of both successful and disastrous national food security management and their outcomes. The invaluable learning experiences of these countries shed light on food security practices, and the straightforward demand-supply framework effectively guides readers in understanding food security issues.

This is an essential resource for anyone who is keen to learn more about food security, particularly researchers and university students who are new to the field. The book endeavours to help us reflect on the current phenomenon and strategize better for the future.
