international dark-sky association

The International Dark-Sky Association (acronym: IDA) is a US-based non-profit organisation incorporated in 1988 by a group of astronomers in order to encourage darker skies (through lighting that creates less skyglow) in the USA, and, eventually, throughout the world by the setting up of other national organisations affiliated with the IDA. They also conduct research into (and campaign on) other forms of light pollution and its non-astronomical (e.g.: health) effects. Although the perceived problem of excessive lighting has existed since the 1950s (and possibly earlier), the IDA were one of the (if not the) first organisations in the dark-sky movement (of astronomers campaigning against skyglow) who are devoted only to combatting forms of photopollution.
