Producing ecological cities Beautifying and making efficient urban areas Cultivating green-based urban growth Developing ecologically sensitive cities
The world's urban population is rising, so that by the end of the century half of humanity may live in cities. Urban populations are rising so fast in lower-income countries that it can lead to extreme environmental degradation, and dirty and unsanitary living conditions. Many such cities, as well as cities all over the world, lack effective environmental or "green" action programs, such as maintaining pollution and litter minimal environments and providing green areas. Parks, for instance, may provide leisure, recreational, and air improvement services, and link urbanites with nature. Communities may need to green their urban environments.
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.
