Question

foster
「.....which is the global situation and the need to foster growth and the fight   against the very low inflation situation 」I'm not sure the meaning of the "foster"or it equal to "enhance ""improve "

Answer

Yes, you are on the right track with foster=enhance/improve.

As Peter suggested,  "encourage" is the best replacement.  "Promote" is another option.

Answer

Yes, a very overused and stale word which means "encourage".
