International tourist arrivals have almost quadrupled over the past 30 years and
domestic tourism has also intensified in most developed and newly industrialized
countries. At the same time, tourist movements have spread geographically to reach

economic sector in terms of income generation, foreign exchange earnings and
employment creation.
