Prefectural Self-Supporting Production of Food and Reduction of its Production and Transportation Energy in Tottori Prefecture

Abstract

To develop low-carbon societies, we should reduce energy consumption in all sectors. In Japan, fuel consumption by the food production and transportation sector is about 15%. In this study, we first investigated the self-supporting production of food in Tottori prefecture. The results showed that the requirements of most nutrients were met except for manganese and pantothenic acid. Second, we examined various strategies under the system of self-supporting production of food. It has been observed that energy consumption can be reduced by 10% when food is not imported. Moreover, about 30% of the energy consumption can be reduced by producing only those foods whose present production exceeds 2000 tonnes/year. Calculations of food production that requires the least amount of energy showed that a reduction of 50% is also possible.
