Introduce the author at the beginning of the quote (narrative in-text citation).
Khoravi (2018) notes the irony in the changes of symbolism and function of humanity's barriers over time.
The current border barriers are built to defend the economic interests of specific units called nation‐states, to safeguard the welfare of the members of these nation‐states, called citizens. Similar to the old walls, the new border walls indicate the nationalist desire for eternity, built to give the impression of being timeless. However, history shows that walls are doomed to fall and, in many cases, to become nothing more than tourist sites. Paradoxically they attract those they were supposed to keep out, the foreigners.

Or include the author at the end of the quote (parenthetical in-text citation).
The symbolism and function of humanity's barriers change over time in a way that is richly ironic.
The current border barriers are built to defend the economic interests of specific units called nation‐states, to safeguard the welfare of the members of these nation‐states, called citizens. Similar to the old walls, the new border walls indicate the nationalist desire for eternity, built to give the impression of being timeless. However, history shows that walls are doomed to fall and, in many cases, to become nothing more than tourist sites. Paradoxically they attract those they were supposed to keep out, the foreigners.
