Discriminatory frequency allocation Overcrowded spectrum of radio frequencies Maldistribution of radio frequencies
The radio frequency spectrum only offers a limited number of frequencies to potential users, despite the expansion of the usable spectrum into the higher frequencies. Faced with a very rapidly rising demand, as the result of the introduction of many new radio and television devices, the spectrum has become congested and exploitation of closely related frequencies has increased interference. It is no longer possible to instal broadcasting or television equipment unless frequencies can be allocated which do not interfere with existing services. Frequency congestion increases the risk for civil aviation because the necessary ground-air communications are inadequate, or menaced by severe interference.
The Encyclopedia of World Problems and Human Potential is a unique, experimental research work of the Union of International Associations. It is currently published as a searchable online platform with profiles of world problems, action strategies, and human values that are interlinked in novel and innovative ways. These connections are based on a range of relationships such as broader and narrower scope, aggravation, relatedness and more. By concentrating on these links and relationships, the Encyclopedia is uniquely positioned to bring focus to the complex and expansive sphere of global issues and their interconnected nature.
The initial content for the Encyclopedia was seeded from UIA’s Yearbook of International Organizations. UIA’s decades of collected data on the enormous variety of association life provided a broad initial perspective on the myriad problems of humanity. Recognizing that international associations are generally confronting world problems and developing action strategies based on particular values, the initial content was based on the descriptions, aims, titles and profiles of international associations.
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.
