The free market economic system that has developed, based on a lifestyle of production, consumption and disposal at volume, places a great burden on the global environment; it is beginning to destroy the delicate balance of the natural environment. Today, there is increasing concern about the finitude of population increase, resources and energy, and environmental capacity; there is clear need for humans in the 21st century, if they wish to maintain safe, secure and healthy lifestyles, to realize a paradigm shift from material wealth to spiritual wealth, and to make this century once in which we are able to realize social systems and lifestyles that are harmonized the ecosystems that make up our environment.

In recent times, the diet of the Chinese population has changed dramatically, moving away from the conventional, grain-rich diet to a meat-rich diet, typical of developed countries. This has caused an increase in the volume of grains required for livestock feed, which in turn has increased overall grain consumption. This change has impacted more than just the material balance of regional communities, or human diet; it has also affected the sustainable development of society. Through my own research, I intend to clarify the impact of lifestyle changes in regional agricultural communities in China on nitrogen and phosphorous flows.

Research Themes

From the perspective of the urbanization of agricultural village communities in China, I examine the impact of the resulting shifts towards urban lifestyle (diet, daily lifestyle, agricultural methods, environmental awareness, etc.) on the environment (water, atmosphere, soil). Specifically:

  1. Analysis of N&P flows in the Yangtze Basin based on field surveys
  2. Actual situation analysis of population fluidity in China
  3. Differences in environmental awareness toward the water environments of Japan and China
  4. Examination to low carbon village
