'produce change' is the definition.
The definition and answer can be both acts as well as being singular nouns.
Maybe they are linked in a way I don't understand?

'rioters again out and about' is the wordplay.
'out' is an anagram indicator (out can mean wrong or inaccurate).
'and' means one lot of letters go next to another.
'about' becomes 'on' (as in a book 'on' a certain topic).
'rioters'+'again'='riotersagain'
'riotersagain' is an anagram of 'reorganisati'.
'reorganisati'+'on'='REORGANISATION'

'to' is the link.
