Actively x Proactively: Como utilizar

According to this website[1], "The Texas Border Sheriff's Coalition (TBSC) has joined BlueServoSM in a public-private partnership to deploy the Virtual Community Watch, an innovative real-time surveillance program designed to empower the public to proactively participate in fighting border crime."

In the paragraph above you will notice the adverb proactively sandwiched between the preposition to and the verb participate. Would substituting the adverb proactively for the adverb actively significantly alter meaning? Mildly perhaps?

Thank you for whatever view that you might have on it.
