Stein van Oosteren is an attaché for the Permanent Delegation of the Kingdom of the Netherlands to UNESCO since 2011. His background in philosophy and psychology have strengthened his drive to maximize the potential of UNESCO as the “UN organization for the human mind” both by better understanding and promoting the organization. Coming from a water country, the Netherlands, he has played an important role in making UNESCO’s International Hydrological Programme (IHP) more visible for a broad audience. As the Chairperson of the IHP Council’s Finance Committee he contributed to increasing IHP’s transparency for decision-makers. He is currently involved in developing UNESCO’s PERSIST programme which addresses the problem of “digital unsustainability”: the fact that our digital information today may no longer be accessible tomorrow because the future software might not be able to read it. Furthermore he played a key role in changing UNESCO’s overall communication about results with a view to increasing impact and support for the organization. Before joining the Permanent Delegation to “plant the seeds of peace” he dealt with cases of organized crime for 10 years as the assistant to the Dutch Police Attaché in Paris.
