How do you calculate self-sufficiency rate?

The self-sufficiency ratio (SSR) is defined as: SSR = production x 100/(production + imports – exports). The SSR can be calculated for indi- vidual commodities, groups of commodities of similar nutritional values and, after appropriate conversion of the commodity equations, also for the aggregate of all commodities.

How do you measure self-sufficient food?

In this sense, the method employed in this study is consistent with that used by FAO to calculate the self-sufficiency ratio (SSR), which is defined as the percentage of food consumed that is produced (SSR = Production x 100 / (Production + Imports–Exports)).
