The database leading to the following visuals aims at characterizing the main actors of the “Geneva international” in the water sector. As of early October 2014, the database counts 52 actors, characterized by 88 numeric and alpha-numeric variables. The three main data sources are Internet search, semi-directed interviews and various exchanges with certain actors. This collection is not exhaustive, and is still growing, but our analysis already leads to convincing results which can be interpreted as guidelines to focus the Geneva Water Hub's activities.
