1.1 DEFINING COASTAL AREAS. Coastal areas are commonly defined as the interface or transition areas between land and sea, including large inland lakes. Coastal areas are diverse in function and form, dynamic and do not lend themselves well to definition by strict spatial boundaries.he multifaceted approach to the management of coastal resources has become known as integrated coastal management (ICM). Pernetta and Elder (1993) have described it as meaning `the process of combining all aspects of the human, physical and biological aspects of the coastal zone within a single management framework'.
More than half of todayâs world population live in coastal areas (within 60 km from the sea) and this number is on the rise. Additionally, among all different parts of the planet, coastal areas are those which are most visited by tourists and in many coastal areas tourism presents the most important economic activity.
