Deserts, concerned with local political division (6)
I believe the answer is:
reward
'deserts' is the definition.
(I've seen this before)
'concerned with local political division' is the wordplay.
'concerned' becomes 're' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'with local' is a charade indicator (letters next to each other).
'political division' becomes 'ward' (I've seen this in another clue).
're'+'ward'='REWARD'
Can you help me to learn more?
(Other definitions for reward that I've seen before include "Bounty for, eg, capturing outlaw" , "Pay" , "'Virtue is its own . . . . . .'" , "Recompense for worthy acts" , "Tip" .)
