The 2016 HABITACT Peer Review took place in Barcelona on the 3rd and 4th of November. HABITACT is a FEANTSA network that focuses on the role of municipalities in tackling homelessness, and the Peer Review is an annual event in which the homelessness services of one particular European city are showcased, with participants attending from around the continent. This year attendees discussed Barcelona’s impressive data collection system on homelessness, the Housing First pilots ongoing in the city, as well as taking part in two site visits of homelessness services run by NGOs. There was particular interest in XAPSLL, the network of stakeholders in homelessness services that has been established in the city. The discussion paper on homeless services in Barcelona written by Dr. Volker Busch-Geertsma is available to read online.
