Japan plans to change the way it sets targets for food security. The move comes amid rising global concern over food shortages following Russia's invasion of Ukraine.
The agriculture ministry is discussing the possible revisions to Japan's food security law, the Basic Law on Food, Agriculture and Rural Areas.
A draft proposal obtained by NHK says a new food security target will incorporate a gauge of the availability of fertilizers into measures of how capable the country is to grow its own food.
It also says the government will establish a new system for properly including production costs in formulating numbers based on selling prices for food.
The draft proposal also calls for studying ways to prevent panic buying and for regulating prices should food supplies become tight in Japan.
