Many of Rome's ancient structures, such as the Bridge of Cestius (Ponte Cestio), first built in 62 BC, are threatened by undercutting by the River Tiber. The cause is the construction of hydroelectric dams upstream which have blocked the flow of sand and silt that renew the river's bed.
A dam being constructed on the third longest river in the world, the Yangtze in China, threatens to submerge around 1,300 sites of historical and archaeological interest, with only the most high-profile sites likely to be rescued in time.
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.
