Phil's comment is correct: the present tense is wrong in this context in English. For an action that began at a specified point in the past (albeit recently: desde el 24 de marzo de 2013) and continues in the present, the perfect continuous must be used.

For "impulsar", promote, encourage and foster are equally valid, and it comes down to personal preference. The order I've given is the order of frequency I get in Google results for these phrases, but that doesn't mean very much really. The differences are not very great; all three are frequent and mean the same.

For emprendimiento, "entrepreneurship" would be the normal word in American English. In British English it is much more common to refer to "enterprise". An enterprise can be a business, which is not the meaning here, but it won't be understood in that sense (that would be "fostering enterprises"). "Enterprise" used like this as a non-count noun means the activity of creating businesses and managing them, with the implication of creative initiative and drive. So the choice depends on the target.
