Food security development in Japan, 1980–2022.

The figure categorizes Japan’s food security into three stages from 1980 to 2022. The first stage is a decline from 1980 to 1993. The second stage is the general rising stage, from 1994 to 2009. The third stage is the stable development stage, from 2010 to 2022. The food security index was high between 2008 and 2009. This is supported by the Fertilizer Security Index and Climate Change Security Index. (PDF)
