This article looks at the use of the ceheval to fulfil public service tasks. After a first comprehensive overview of the diversity of local initiatives that can be met in the national territory, our attention has focused on the case of some local authorities. It was for us to better understand why and how they used the horse to perform public tasks. We have chosen as a study case the municipalities of Vendargues, Beauvais, Trouville-sur-Mer and Saint Pierre in Dives, the Valleuse d’Antifer site, the vendéan marshes and the syndicat mixte de la site du Canigou, eight cases which clearly reflect the diversity of the situations observed in the initial census, in terms of territories and missions (from urban garbage collection to protection of protected natural areas). For each of these actions, we conducted field surveys combining direct observations and semi-directional interviews with several people involved. The content of the 30 interviews carried out was the subject of a qualitative analysis aimed at developing cross-cutting lessons on how projects were set up, how they were developed and their effects.
