Many science communication practitioners engage in regional networks, using the multiplier effect for broader reach. The idea is to engage more people with science and technology more locally and more effectively. How can we set up such networks and what kind of facilitation do they require? What is the special value of regional connections and organizational diversity? How can we engage network partners in knowledge sharing and dissemination? How can we sustain regional networks? In this reverse session, four national/regional networks – Portugal (Sciencia viva), Austria (ScienceCenter-Network), Italy (UmbriaScienza) and Poland (Explorers Clubs Network) – will share their experiences on network formation and governance, network theory, political relevance and rapidly expanding partnerships.
