The problems of mass catering for holidaymakers are often intensified in the less developed countries which have the climate, scenery, and local rural customs that attract tourists from colder, industrialized, and urbanized countries. Mass tourism is an excellent method of earning foreign currency, and most countries are eager to capitalize on it - sometimes at the expense of maintaining adequate health care provisions. A rapid development of tourist hotels may create a strain on local sanitation facilities, causing visitor health problems by polluted bathing or drinking water; there is often a lack of knowledge locally of the technology of mass catering, and perhaps a shortage of semi-skilled workers; and hygiene habits of the workforce may be unsatisfactory and lead to illness. In addition, in an apparently modern hotel, tourists may not take the precautions they would normally take when visiting a foreign country. They may drink unboiled milk in the belief that it is pasteurized; eat fruit and salads under the impression that they have been washed in clean water by clean hands; may overlook that the ice cubes in their drinks may have been made from tap water; and may forget that in many developing countries it is not the custom to store meats under refrigeration.
The Encyclopedia of World Problems and Human Potential is a collaboration between UIA and Mankind 2000, started in 1972. It is the result of an ambitious effort to collect and present information on the problems with which humanity is confronted, as well as the challenges such problems pose to concept formation, values and development strategies. Problems included are those identified in international periodicals but especially in the documents of some 60,000 international non-profit organizations, profiled in the Yearbook of International Organizations.
The Encyclopedia includes problems which such groups choose to perceive and act upon, whether or not their existence is denied by others claiming greater expertise. Indeed such claims and counter-claims figure in many of the problem descriptions in order to reflect the often paralyzing dynamics of international debate. In the light of the interdependence demonstrated among world problems in every sector, emphasis is placed on the need for approaches which are sufficiently complex to encompass the factions, conflicts and rival worldviews that undermine collective initiative towards a promising future.
Non-profit, apolitical, independent, and non-governmental in nature, the UIA has been a pioneer in the research, monitoring and provision of information on international organizations, international associations and their global challenges since 1907.
