For comparison, a man occupies about 5 square feet of space when he is walking. A car occupies about 350 square feet when it is standing still (including access); and at 30 miles an hour, when cars are 3 lengths apart, it occupies about 1000 square feet. Most of the time, cars have a single occupant. This means that when people use cars, each person occupies almost 100 times as much space as he does when he is a pedestrian. It is also notable in cities that when the area devoted to parking is too great, it destroys the land. Empirical observations suggest that an environment is not fit for human use when more than 9% of it is given over to parking. Another factor in the use of land by the automobile concerns the amount of paved road and highway that becomes necessary for its use. For example, in downtown Los Angeles more than 65% of the land is covered with concrete or asphalt paving. In Houston there are 30 parking spaces for every resident.
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.
