family planning

I'm a little stuck... Click here to teach me more about this clue!

'it may result in issue being avoided' is the definition.
The definition suggests a singular noun which matches the answer.

'tribe having powwow?' is the wordplay.
'tribe' becomes 'family' (family is a kind of tribe).
'having powwow?' becomes 'planning' (I can't explain this - if you can you should give a lot more credence to this answer).
'family'+'planning'='FAMILY PLANNING'
