The project ‘Building Capacities for Effective Implementation of the Arms Trade Treaty (ATT)’ has been implemented by GCSP since 2014 and received funding for multiple project phases from the United Nations Facility Supporting Cooperation on Arms Regulation (UNSCAR). The project aims to increase the knowledge base of participating individuals on the implications of ATT provisions and of relevant existing practises of, and options for, their effective implementation to transfer information and expertise back to states. The project includes week-long five-day training courses (in English in Geneva, in French in Africa) for practitioners from governments active in the implementation of the ATT. The courses seek to improve the capacity of governments and individuals to implement the Treaty and establish a community of practitioners to continue information and experience exchanges as well as mutual assistance in addressing the challenges of the ATT.
