Estimates of health effects are often based on very uncertain assumptions: both population exposure patterns and the shape and magnitude of the exposure/response relationships. The estimates of population exposure must be improved by more reliable and relevant modelling and monitoring of air quality. Assessment of population exposure might be improved significantly by making existing air quality data more readily accessible. This must be done not only for the purpose of carrying out a Europe-wide assessment but also to optimize national and local strategies for reducing pollution. Better exchange of information is also important in assessing the effectiveness of local and regional measures to improve air quality. Assessing population exposure to hazards in indoor air requires a different approach, including household surveys.
The Environment Protection Authority of New South Wales has the best emissions inventory for any Australian region, covering the emission sources and their relative contribution to air pollution. The monitoring network reports air pollution indices three times a day for the Sydney region.
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.
