Scarcity (6)

I believe the answer is:
dearth
'scarcity' is the definition.
(dearth is a kind of scarcity)
This is the entire clue.
(Other definitions for dearth that I've seen before include "Lack of resources" , "Shortage, paucity" , "In short supply" , "Hatred (anag) -- shortage" , "Severe lack" .)
