Can someone acquire government land by occupying it long enough?

Two rules in two sentences

The first is permissive: all things which are within the commerce of men are susceptible of prescription, unless otherwise provided. The second is a carve-out: property of the State or any of its subdivisions not patrimonial in character shall not be the object of prescription. So the answer for government land is not a flat no, and it is certainly not a yes. Everything turns on which side of the patrimonial line the particular parcel falls, and that is a question about the character of the land rather than about how long anyone has been sitting on it.

“Patrimonial” is the whole question

Patrimonial property is property the State holds in the way a private owner holds his own, as distinct from property devoted to public use or to a public service. Roads, plazas, riverbanks and land held for a government purpose are not open to acquisition however long the occupation has run, and no quantity of tax declarations or improvements alters that. The distinction is not visible from looking at a parcel, and occupants routinely assume that unused or unfenced land must be free for the taking. Unused is not the test.

Much of this is not a Civil Code question at all

Article 1115 provides that this Title operates without prejudice to what this Code or special laws establish for specific cases of prescription, and the classification and disposition of public land is governed by exactly that kind of special legislation. So what a long-time occupant usually needs answered is not the question this article poses, but whether the parcel has been classified and released in a way that allows any claim to be made at all, and by which route it would have to be made.

Establish what the land is before anything else

The classification of the parcel, the agency that holds or administers it, and any issuance covering it are the documents that decide the case; a survey plan and the assessor's records tell you what is being claimed and by whom. Ordinary possession evidence matters only once the land is shown to be capable of being acquired — Article 1118 requires possession in the concept of an owner, public, peaceful and uninterrupted, but that requirement never comes into play if the land was never susceptible in the first place.
