Quantitative Data Analyses for the Recent Change of the Japanese Food Self-Sufficiency Ratios
Food security has for long become a significant issue in the islands of Japan. The problem arose with the decreasing food self-sufficiency ratio (FSSR) in almost every food item in the country.FSSR in Japan has been experiencing a steadily declining trend over the past 4 decades.First we compare international FSSR data for all OECD countries concluding that Japan is the least in food supply on an average term. Then we try to investigate the changes in the FSSR by decomposing into those in both FSSR and its demand for each food item.In a general term,annual change in food self-sufficient ratio is assumed to be the combination of the factorial change in the quantity of food items being supplied/consumed in terms of kilo-calorie,and the factorial change of food items self-sufficient ratio themselves.We investigate FSSRs by money order in order to show their regional characteristics in Japan.Finally strategies for improving Japanese FSSR are discussed.
