Food security is pivotal for a nation’s well-being, defined as the availability, accessibility, and affordability of food to all people at all times. It goes beyond merely providing adequate food; it involves dimensions of availability, such as local production, imports, and reserves; accessibility, meaning food must be within reach; and affordability, implying individuals must have the financial means to purchase nutritious food. In India, effort to achieve food security has been critical, especially in the context of historical famines like the Bengal Famine of 1943, when many were rendered food insecure due to natural disasters. The section highlights various characteristics of food security, discussing challenges various demographics face — like landless laborers and seasonal workers — and the implementation of governmental policies such as the Public Distribution System, which plays an essential role in alleviating food insecurity through accessible food at lower prices.
