16.7 Discussion and Risk Prevention
The problem of natural and anthropogenic hazards and risk prevention is attracting
more and more attention of both scientists and spatial planners. Since the 1960s,
The world coastal zones are among the most threatened and, at the same time, the
most populated areas.
