Information should be made available to the public in an accessible and user-friendly manner. This will usually involve interpretation, structuring and analysis of information according to the needs and interests of the public, though always without prejudice to the right of access to the original data. State-of-the-art internet web sites linking databases on emissions to environmental media (in the form of geographical information systems) with databases on the health implications of toxic chemicals have demonstrated that there is a dramatic increase in the public use of information when the information is presented in a user-friendly form through an electronic "one-stop-shop". There is also a need to provide NGOs and the public with better information on how to interpret data on environmental and health issues.
Agenda 21 recommends that countries, in cooperation with the scientific community, should establish ways of employing modern communication technologies for effective public outreach. National and local educational authorities and relevant UN agencies should expand, as appropriate, the use of audio-visual methods, especially in rural areas in mobile units, by producing television and radio programmes for developing countries, involving local participation, employing interactive multimedia methods and integrating advanced methods with folk media.
