If not more police/policing, what is the appropriate response to an increase in crime?

There has been a notable rise in violent crime in San Francisco, including carjackings, muggings, and burglaries. Here in the Bay Area, police have been unpopular especially since the George Floyd protests of last year and some cities have controversially reduced the sizes of their police departments. “Defund/abolish the police” is very popular here. If the response to more crime isn’t more policing, then what is the appropriate response? What should communities do about an increase in crime?
