Compensation required for port area in ruins (10)
I believe the answer is:
reparation
'compensation' is the definition.
(I know that reparation is a type of compensation)
'port area in ruins' is the wordplay.
'ruins' indicates an anagram.
'port'+'area'+'in'='portareain'
'portareain' with letters rearranged gives 'REPARATION'.
'required for' is the link.
(Other definitions for reparation that I've seen before include "compensation" , "The making of amends for a wrong" , "damages" , "process of putting things right again" , "make redress" .)
