Neglect of the elderly or their outright rejection are intolerable. Their presence in the family, or at least their closeness to the family in cases where limited living space or other reasons make this impossible, is of fundamental importance in creating a climate of mutual interaction and enriching communication between the different age-groups. It is therefore important to preserve, or to re-establish where it has been lost, a sort of "covenant" between generations. In this way parents, in their later years, can receive from their children the acceptance and solidarity which they themselves gave to their children when they brought them into the world. This is required by obedience to the divine commandment to honour one's father and mother (cf. Ex 20:12; Lev 19:3). But there is more. The elderly are not only to be considered the object of our concern, closeness and service. They themselves have a valuable contribution to make to the Gospel of life. Thanks to the rich treasury of experiences they have acquired through the years, the elderly can and must be sources of wisdom and witnesses of hope and love. (Papal Encyclical, Evangelium Vitae, 25 March 1995).
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.
