This book is the result of a one-day Seminar on 22 October 2013, in Rio de Janeiro, organized by the Alexandre de Gusmão Foundation (FUNAG) in collaboration with the Istituto di Studi Avanzati and the Department of Political and Social Sciences of the University of Bologna, scholars from different parts of the world discussed the topic “Global Governance: crossed perceptions”. The idea was to inquire from different perspectives about the prospects for what appeared to be an international system under pressure to adjust to economic and political changes so as to increase governance legitimacy and to be able to cope with challenges of global reach and nature.
