Analysis of the Household Food Stocks for Disaster

Abstract eng:
In Japan, a lot of natural disasters are expected to occur such as typhoon, heavy rain, heavy snowfall, flood, sediment disaster, earthquake, tsunami and volcanic eruption. In the future, large scale earthquakes, such as the Nankai Trough earthquakes are expected to occur with a high probability. When these disaster occurs, goods required for life especially food are needed. However, immediately after the occurrence of a major disaster, since the rescue of the injured people has priority and the traffic is stopped for long time, the goods such as food is assumed to be delivered late. In the event of a disaster, self-help and mutual assistance of the residents are important rather than public aid supplied by government. Therefore we should break away from the way of thinking to rely on public aid and to stock goods for disasters. The purpose of this study is to examine self-help and mutual assistance of residents using the household food stocks. We investigate the amount of food in the home, and consider whether we can cover the meal at the time of a disaster to use the household food stocks. Thus, we conduct a survey to analyze the amount of household food stocks in peacetime in Kanazawa (the provincial city) and Tokyo (the big city), and calculate the food basic unit. Moreover, we perform a simulation which assumes disaster, and examine self-help and mutual assistance of residents using the household food stocks. As a result, we find that there are more household food in Kanazawa than Tokyo. The total calories of meat, seafood, and vegetables are short of the calories which are necessary to refuge life for one day in both Kanazawa and Tokyo. In the future, we will perform a simulation that assumes the Nankai Trough earthquakes using the provincial city model and the big city model.
