There is no zero risk for disasters. However, it is necessary to prepare for disasters and take measures to reduce risks. Even if we build a vast seawall to completely prevent tsunamis, it cannot overcome the power of nature. Some people say that it is a waste to spend 1.4 trillion yen to rebuild the seawall destroyed by the tsunami of the Great East Japan Earthquake. Considering the current economic situation, reducing risk at low cost is a rational method. Rather than spending a lot of money to seek perfection, it is better to find a way to avoid risk at a low cost. It is self-evident that it is cheaper to sense a tsunami early and train your strength to run to higher ground.
Every year, rivers flood one after another due to rain and wind. Low-lying areas are becoming dangerous areas covered in water. Coastal areas are becoming more susceptible to severe damage due to erosion. These are caused by the changing climate due to global warming. Unexpected heavy rains and typhoons are occurring. In addition to global warming, there is population movement due to urbanization, and the reality is that former Satoyama are rapidly becoming desolate. Considering this situation, it will be difficult to repair 694,000 dangerous areas, mainly in rural areas. At the level of a local government with a debt of 200 trillion yen, it will be impossible to repair. Of course, it will also be impossible at the level of a country with a debt of 1,000 trillion yen. The power of nature is too strong, and it is not realistic to continue to return roads and collapsed mountainside to their original state.
The disorderly suburban spread of cities is increasing administrative costs. And, as seen in recent years, it has created areas that are vulnerable to disasters. It will take time to change the land use pattern from proliferation to reduction and realize the improvement of the constitution. However, if this improvement can be made, there is a possibility that problems such as cities, transportation, welfare, and finances can be solved cross-sectionally. If the safety of residents can be protected with a small budget, it can be said to be an ideal local government. Spending a large budget on disaster recovery cannot be said to be rational administration. Wisdom and ingenuity in gathering people in places that are not prone to disasters is also good governance. What is important is the perspective of how much people can enjoy life and have a sense of purpose in that comfortable environment. Local governments that provide safe and secure places, good physical environments, and rewarding environments may become model cases in the future.
