Today Japan has a serious problem about the self-sufficiency ratio for food. The ratio of Japan was about 80% 50 years ago, but the ratio is 39%. The number is quite low among other developed countries. Most food that we eat is from other countries. Japan depends on importance from other countries. So Japanese people will not have food to eat if other countries stop exporting food into Japan. Japan has to consider solutions so that the crisis will not happen. Then there are several solutions to raise the self-sufficiency ratio for food. The first solution is that each house has a kitchen garden. Another solution is that schools in Japan encourage students to be involved in volunteer works in a farm village. The best solution is that Japanese government raises the price of food imports.
The first solution is that each house has a kitchen garden. If we raise vegetables in each kitchen garden, we do not have to buy vegetables. Moreover it can improve the self-sufficiency ratio. We do not need large space for kitchen garden. It is easier to raise vegetables with plant pots. If we raise vegetables by ourselves, we could surely savor them.
Another solution is that schools and universities encourage students to be involved in volunteer works in a farm village. Today it is elderly people that support farming of Japan. However more and more farm villages are disappearing in Japan, because only elderly people cannot maintain farm villages. Therefore the force of young people is necessary in order to keep farming. Schools and universities should encourage students to participate volunteer works in farming. That also could deepen interchanges between young and old.
The best solution is that Japanese government should raise the price of food imports. Generally, food imports is cheaper than domestic food in supermarkets. So, if food imports is more expensive, more and more people would buy domestic food. That can raise a supply of domestic food and improve the self-sufficiency ratio of Japan. On food imports, we do not know exactly who is the producer. If the name of producer is written on domestic food, we can eat buy and eat them in peace.
The self-sufficiency ratio keeps decreasing, besides the price of food is soaring. Therefore we never ignore this problem. Each everyone has to awake to the crisis of self-sufficiency of food.
