Data collection and information development are essential prerequisites for
  coastal adaptation. The more relevant, accurate and up-to-date the data and
  information available, the more targeted and effective adaptation can be. Coastal
  adaptation requires data and information on coastal characteristics and dynamics,
  patterns of human behaviour, as well as an understanding of the potential consequences
  of climate change. It is also essential that there is a general awareness amongst
  the public and coastal planners and managers of these consequences and of the
  possible need to act. In countries where the central government has neither
  the means nor the expertise to address problems in every part of the coast,
  the information is used most effectively when targeted at the most influential
  people in the community.
  
  Large-scale global and regional databases exist for a great number of climatic
  and socio-economic variables relevant to coastal zones. These databases may
  be accessed and downloaded from the Internet. However, coastal adaptation to
  climate change cannot rely exclusively on these readily available databases.
  Table 15.1 lists a number of relevant technologies that can serve to increase
  the understanding of the coastal system (which involves data collection and
  analysis), to conduct climate-impact assessment in coastal zones and to raise
  public awareness. Where appropriate, reference is made to publications that
  either describe the technology in detail or provide examples of its application.
  Further information on a broad range of technologies for coastal-system description
  can be found in Morang et al. (1997a), Larson et al. (1997), Morang et al. (1997b)
  and Gorman et al. (1998). Bush et al. (1999) described the use of geoindicators
  for rapid coastal risk assessment, while Capobianco (1999) discussed technologies
  in relation to integrated coastal zone management.
