Private coastal spaces benefit a handful of people while public spaces benefit millions of people. The problem is the same in developing and developed countries. In southern Europe you can often see the beautiful Mediterranean but access to the sea is difficult because of private lands, through which you cannot even walk to the sea. The problem is the same in the Caribbean, where the local people commonly have lost access to some of their traditional beaches, because the access routes have been taken over by international hotel chains.
Respecting everyone’s right to shore access is a common issue to be solved in coastal zone management. In many countries at least the shore area up to the highest tide mark is public. Often there is also a wider, construction-free public set-back area on the shore. Nevertheless, the access to this area where people have traditionally kept their boats and gone for a swim, has often been blocked by private properties.
The solution is not to forget the public access routes to these places. The best example on how to respect everyone’s right to nature, both marine and terrestrial, is provided by the Nordic countries, in which “every man’s right” is a traditional legal concept. You may spend time within a private land area and walk through it to the beach without asking permission. The only exception are people’s houses, the privacy of which you need to respect.
