Short answer. Yes. Article 571 of the Civil Code gives the usufructuary the right to enjoy any increase the usufruct property acquires through accession, any servitudes established in its favor, and all other benefits that are inherent in the property — including those that arise after the usufruct begins.
What the law says
The usufructuary shall have the right to enjoy any increase which the thing in usufruct may acquire through accession, the servitudes established in its favor, and, in general, all the benefits inherent therein.

The usufruct grows with the property
Article 571 of the Civil Code establishes an important principle: the usufruct is not frozen at the condition the property was in when the usufruct began. If the property grows — through accession — the usufruct grows with it. The usufructuary has the right to enjoy any increase the thing may acquire through accession. This means that if a riverbank widens naturally and adds land to the property, or if a building is extended through additions, the usufructuary enjoys the benefit of the added portion for the duration of the usufruct.
Servitudes that benefit the property
Article 571 also gives the usufructuary the right to enjoy any servitudes established in favor of the property. A servitude, or easement, is a right that one property holds over a neighboring property — a right of way, a right to draw water, a right to receive light and air. If such a right is established in favor of the usufruct property either before or during the usufruct, the usufructuary can exercise it. They do not have to negotiate separately with the neighboring landowner — the easement belongs to the dominant estate they are enjoying.
All benefits inherent in the property
The article closes with a broad catch-all: the usufructuary is entitled to all the benefits inherent therein. This is a sweeping provision. Any benefit that attaches to the property by reason of its nature, its location, or existing legal rights flows to the usufructuary for the duration of the usufruct. The usufruct is not merely a right to collect what the property was producing on day one — it is a right to enjoy the property as a full economic unit, including whatever advantages the property carries or acquires.
What this means in practice
If you hold a usufruct and you learn that the property has been extended through alluvion, or that a new easement has been registered in favor of it, or that any other benefit has attached to the property, you are entitled to enjoy those advantages just as you enjoy the original subject of the usufruct. Conversely, if you are the owner of a property subject to a usufruct, you cannot unilaterally redirect accessions or benefits away from the usufructuary during the usufruct period. Any dispute about whether a particular benefit falls under Article 571 — and therefore belongs to the usufructuary — is worth clarifying with a lawyer early.
