The coastal zone is one of the most densely populated areas globally because of favourable locational factors‚ yet it is an area of immense environmental value. This topic allows students to carry out detailed studies of contrasting coastal environments at a local/ small scale‚ exploring competing and conflicting land uses‚ and evaluating the pressures created by development. It considers how vulnerable and valuable coastlines face a growing physical risk from rapid coastal erosion and coastal
