Short answer. No. Civil Code Article 713 limits occupation as a mode of acquiring ownership to things that are “without an owner” by nature, such as wild animals, hidden treasure, and abandoned movables. Land in the Philippines is never ownerless in that sense, so occupation does not make you its owner.
What the law says
Things appropriable by nature which are without an owner, such as animals that are the object of hunting and fishing, hidden treasure and abandoned movables, are acquired by occupation.

Occupation only works on things without an owner
Article 713 is built around a single condition: the thing has to be “appropriable by nature which are without an owner.” The examples it lists — “animals that are the object of hunting and fishing, hidden treasure and abandoned movables” — are all things that, by their nature or by having been abandoned, currently belong to nobody. Occupation lets a person become the owner precisely because there is no existing owner being displaced.
Land does not fit that description
Registered or unregistered, privately titled or classified as public land, real property in the Philippines is always attributed to someone — a private owner, or the State where it has not been alienated. It is never the kind of ownerless, appropriable-by-nature thing Article 713 describes. Occupying land that already belongs to someone, whether a private party or the government, does not trigger this mode of acquiring ownership, no matter how long or open the occupation is.
The Code says so in terms in the very next article. Article 714 provides that the ownership of a piece of land cannot be acquired by occupation, which removes any argument that a particular parcel might be the exception because nobody appears to be using it. Occupation remains a real mode of acquiring ownership — it is simply confined to movables and to the ownerless things Article 713 lists.
Where the confusion usually comes from
People sometimes assume that living on unused or seemingly forgotten land for years works the same way as claiming an abandoned object. It does not, because the land itself is not abandoned in the legal sense Article 713 requires — a piece of property having no visible activity on it is not the same as it having no owner. Long, continuous possession of land is instead addressed by other doctrines in the Civil Code, entirely separate from occupation.
What actually governs long possession of land
If your situation involves years of open, continuous possession of land rather than picking up something genuinely ownerless, the relevant framework is prescription, not occupation — a different set of rules with its own requirements about the length and character of possession needed. Confusing the two can lead someone to believe they have already become an owner when the legal basis for that claim, under Article 713 at least, simply is not there.
Prescription is also narrower than it is often assumed to be. It asks for possession in the concept of an owner — open, continuous, exclusive and notorious — so occupation that began by tolerance of the owner, or with rent paid, generally does not start the clock at all. Land of the public domain is outside it until the State has classified the land as alienable and disposable, which is a matter of official record rather than of how the ground looks.
