More number of destinations throughout the world have opened their doors to and invested in tourism thus turning the sector into a prominent generator of socio-economic progress by way of export revenues, infrastructure development and generation of enterprises and jobs. Over the course of the past six decades, the sector has witnessed continued diversification and expansion to become one of the biggest and rapidly growing economic sectors globally. New destinations have emerged in plenty to add to the already existing conventional attractions of North America and Europe. Withstanding occasional disruptions, international tourist arrivals have registered virtually a string of uninterrupted growth from in 1950 what was 25 million to 278 million in 1980, in 1995 to 528 million and in 2013 to 1087 million.
The long term outlook for world tourism looks extremely healthy. As per the long term forecast published by the UNWTO titled Tourism Towards 2030, globally international tourist arrivals are projected to grow by 3.3% annually from 2010 till 2030 to attain 1.8 billion by 2030. The growth rate in arrivals in emerging destinations between 2010 and 2030 at plus 4.4% per annum are expected to grow at twice the rate than the ones in advanced economies that pale in comparison at 2.2% per annum (Weaver and Lawton, 2010). The emerging economies market share showed a rise from 30% in 1980 to forty seven percent in 2013. It is forecast to attain 57% by 2030, which translates to in excess of one billion international tourist arrivals.
