Riga cultural organisation is not urban in its outlook (12)
I believe the answer is:
agricultural
'not urban in its outlook' is the definition.
I can't tell whether this definition defines the answer.
'riga cultural organisation' is the wordplay.
'organisation' indicates anagramming the letters.
'riga'+'cultural'='rigacultural'
'rigacultural' with letters rearranged gives 'AGRICULTURAL'.
'is' is the link.
Can you help me to learn more?
(Other definitions for agricultural that I've seen before include "Rural; farmed" , "Relating to farming" , "Lulu Craig art (anag.)" , "Related to farming" .)
