J'ai besoin d'aide pour expliquer "si" Bonjour a tous

I understand that the Word "si" can mean if or so. In this phrase what does it mean. 

"Plan si coupure" does it mean plan for cuts I.e budget cuts etc  . Ideally it would have more context but this all I had. In my opinion it means "to" or "for"

The help is much appreciated,
