Coastal adaptation

Around the world, coastal defenses are an integral part of climate policy. The risk of flooding is increasing due to a number of factors – the rising sea level (which in the Netherlands is being exacerbated by subsidence), the increasing intensity of storms and rising water levels in rivers. The Dutch parliament is currently looking at proposals for a new Delta Law, which is designed to address these increasing dangers. This law, as well as the legislation that already exists, is among the most advanced in the world. But of course, that is because half of our country is susceptible to flooding, either from the sea or from rivers.
Unlike in the Netherlands, most of the coastal areas around the cities of southern and eastern Australia are in the hands of private landowners. These ‘ocean view properties’ are spectacular, and extremely expensive. That makes it difficult for the government to build coastal defenses. Many interesting legal cases are already underway in this area which will clarify how this aspect of climate law will be put into force in the future. Essentially, the law states that the authorities must create a coastal protection area where they can make provisions for the effects of climate change. This policy will determine whether projects in coastal areas are allowed to go ahead. But what should be done in cases where houses are under threat from the sea?
One of the most famous cases is that of a rich landowner in Byron Bay to the south of Brisbane. The government had decided not to defend a section of the coastal area against the increased risk of erosion, but rather to let nature take its course as a part of a wider plan that involved protecting other, more important areas. The owner of the land decided to take measures to protect the land from erosion himself by renewing the old coastal defenses. The government denied him permission to do this, for the same reason as it had decided not to do so itself. When it looked as if the dispute would be settled in favor of the landowner, the government decided to renew the coastal defenses after all. However, it is clear that this is only a temporary measure until the next storm comes along. There is no prospect of a definitive solution, not least because land owners are opposing the construction of new coastal defenses for the future. After all, this would mean their land would no longer be located directly on the coast, and so it would be worth considerably less...
