The term human security and development have undergone major change in the light of national security. Both are non-traditional elements of security. They are mutually interrelated to each other. A nation cannot imagine proper development with no reference to human security. Human security is mostly concerned with ‘freedom from fear’ and ‘freedom from want’. If a nation is able to protect its individual from fear and gives ample opportunity of freedom to fulfil its basic need then a nation can progress and secure its territory. The author tries to analyse the conceptual aspect of human security and development. Hence, enhancement, value progress, economic welfare due to modernization have clear bearing on the notion of human security.
