Abstract
Until now, the Southeast and South Asia region has been slow to develop economically and has accumulated a small amount of damage. As a result, the scale of damage has been limited despite the relatively large scale of disasters. However, rapid economic growth and delayed development of social infrastructure have resulted in the accumulation of damage targets, and extensive damage has been occurring every year. This increase in the number of disasters is becoming an opportunity for the potential vulnerabilities and problems of the society in question to become a social problem. This interest in disasters as social problems has reminded us of the fact that existing hardware-centered disaster prevention measures alone will not result in disaster mitigation, and the policy shift to "watershed flood control" has indeed illuminated the "limits of technological theory. As the scale of disasters is expected to increase in the future, it is urgent to consider not only engineering disaster prevention measures but also local relationships between nature and humans from the viewpoint of disaster mitigation, and solving the problems of "depopulation" in rural areas, as well as the "separation" of family farms, which produce 80% of the world's food supply and are less dependent on fossil fuels.
Therefore, this study sets up a comparative axis of "depopulation" and "abandonment of agriculture" as "global problems" that are economically common phenomena, and specifically analyzes the background and current status of "depopulation" and "abandonment of agriculture" in each country and region.
