Threats to India's coastline are set to exacerbate with climate change, causing higher sea levels, unpredictable precipitation and frequent storms. Japan, on the other hand, has what Fuminori Kato of the National Institute for Land and Infrastructure Management describes as steep coasts, where mountains run directly into the sea and tectonic plates meet nearby. On the topic of whether or not some people believe that the addition of concrete is ruining the visual beauty of the beachfront in Japan, Kato quickly notes that those people living in impacted coastal regions (about 130 million of them) are far more concerned about their safety than any picturesque viewespecially in the wake of 2011s devastation and continued threats.

Regardless of unknown variables, the minimum projected rate of beach loss in the near future is 18%, according to the study. If the environmental foundation is not maintained over long time scales (say, decades), the ecological, disaster prevention, and human utilization functions of coastal zones will suffer. Their attitude is one that feels more practical, and bleak, than anything ever expressed in the US when it comes to natural disaster prevention.
