It is a metaphorical usage reflecting the fact that something that is held up high (elevated) is easier for people to see.

Maybe he is using “communal” in the sense of “distinct social or political groups within a country.” If so, then “inter-communal strife” would mean more anger/distrust/fighting between such groups.
