Socio-cultural impacts are the third principal consequence, along with economic and environmental ones, of large scale visitor arrivals at tourism destinations. As De Kadt E (1979) and Cooper C et al (1993) both observe, there are three sources of socio-cultural impacts at such places. These are tourists, hosts, and their (i.e. tourist/host) interactions.
A basic factor in this relationship is that hosts gain economically (or usually intend to) from their contact with visitors, but they or their community may experience some unexpected (and sometimes also undesirable) socio-cultural consequences. At the same time, the visitor is a stranger and therefore may be vulnerable to being cheated by the local people - or even robbed.
