Life is more comfortable and easier in the urban areas. The level of development of infrastructure and amenities is far greater in the urban than rural areas especially in developing countries. Those who are educated and are therefore in a position to help often find it difficult to go back to the rural areas to live under conditions where basic facilities for reasonably comfortable living are non-existent or barely minimal. Going to rural areas to teach is even more difficult if teachers have been educated in urban areas. Frequently, the status of a teacher depends on how close to an urban area his school is.
In many countries of Africa there are more than 2000 farmers for each agricultural extension worker.
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.
