'cooperatively-managed' originates from the combination of 'cooperative' and 'manage', where 'cooperative' comes from Latin 'cooperari', meaning 'to work together', and 'manage' from Italian 'maneggiare', meaning 'to handle'.

'cooperatively-managed' evolved from the concept of 'cooperative management' in the 19th century, emphasizing shared responsibilities.

Initially, it meant 'to manage with cooperation', and this meaning has largely remained the same in modern usage.
