The Global South Unit for Mediation (GSUM)

The Global South Unit for Mediation (GSUM) is a research, teaching and learning platform devoted to the production, debate and diffusion of knowledge and expertise on the broad spectrum of peace-related activities and conflict transformation mechanisms, including international peace negotiations, mediation and peace operations. Our research, international seminars, workshops, publications and training materials share a focus on the Global South.

Launched in 2013, GSUM is an initiative of the Institute of International Relations of the Pontifical Catholic University of Rio de Janeiro (PUC-Rio) through the BRICS Policy Center. Underpinned by the last five years of innovative experiences and positive results, the Unit is now recognized as a relevant institutional space for fostering the interaction among scholars, diplomats, governmental officials and non-governmental actors interested in peacemaking, peacekeeping and peacebuilding processes.
