Modern society is globalized, and in such globalized world, materials, money and man move across the national boundaries, contributing to economic development. However, what moves in such a way is not limited to "what is good," and harmful wastes such as mercury and lead move across the national boundaries as narcotic drugs and weapons do.
In other words, development and environment, and furthermore peace and human rights are intricately intertwined. My research theme is to analyze a flow of materials, money and man in this globalized world, and make economic analysis of "new sustainable development" in due consideration of development, environment, peace and human rights.
For this purpose, it is necessary not only to use statistics and data of each country, but also to make a field study by staying in developing nations. I have so far visited and investigated villages, fishing villages, small factories, slums, and garbage collection sites of Philippines, Thailand, Indonesia, Nepal, China, Mexico and Peru. It can be said that this kind of research requires not only knowledge, but also physical strength.
