Belgarena is an active supporter of the Sambre River Contract and the "Maison Wallone de la Pêche". The company has invested some of its own funds in the acquisition and placement of metal baskets designed to provide fish with protected spawning grounds.

A Monitoring Committee composed of the authorities of the Walloon Region, Farciennes city officials, and residents meets each year to review the actions taken and suggest improvements.
