Hi @Samarou,
Thank you for your contribution! 

I've reviewed OSM and noticed that the following element already exists: 
"Direction Préfectorale de l'Environnement de Tchaoudjo (DPERF-Tch)" (office=government)
https://osm.org/node/11997577969

Could you please confirm if this matches the details in your note?
