Can We Create Zero-Emission Society of Food Production and Consumption in Japan?

Abstract

Food production and consumption must be in natural material cycle in order to create the zeroemission society. Minimum requirement of amble land area in order to create zero-emission society in Japan is discussed from the concept of nitrogen balance. Appropriate agricultural technologies to sustain zero-emission society are also considered. Since food self-sufficiency rate in Japan is quite low, it is difficult to create zero-emission society. It is impossible to create zero-emission society by improving efficiency of recycle technologies. Zero-emission society must be discussed with the agricultural and food self-sufficiency policies in Japan
