Due to the mountainous topography of the Basque Country, livestock breeders often lose a lot of time by going to seek their herd in the mountains every day, which is especially stressful for part time farmers. Thus, the livestock breeders expressed a need for change in the livestock management. This need was detected by The Sectorial Network team of Hazi Foundation, the public foundation of the Basque Government for rural and coastal development. In response, HAZI developed, in close collaboration with some farmers, GEOPOS, a livestock geo-localisation device.
