I would say straight off that 'scarcity' is the most commonly used and I think that many people would struggle to explain 'paucity' or even 'dearth'.
In common with most people, the word 'dearth' equates in my mind to an absence of something. 'Paucity' I think comes from the Latin word for 'little' but 'thefreedictionary' gives them as synonyms.
The reason that you might have synonyms is that the words may have come from different languages: describing the 9th century Viking invasion of England, Bernard Cornwell explains how, once King Alfred had united the Danes and the English, that terms from the two languages started to be used interchangeably.
Where there are subtle differences or even larger differences, native speakers quite use several approximate terms to describe something indicating that they have only a hazy general idea of the meaning.
