ABSTRACT
Further, while they have become more active in their own right, more and more regional institutions have also become involved in collaborative security ventures, typically with the UN, but also with other regional/cross-regional institutions, and an array of non-governmental organizations (Pugh and Sidhu 2003). This collaboration is particularly evident today in the area of peace operations (see Chapter 27, this volume). Since the 1990s a growing number of major peacekeeping operations have counted on the participation of the UN and a variety of regional organizations. At the end of 2005, some 15 regional organizations were involved in collaborative peacekeeping/peacemaking activities (CIC 2006). Member states of the African Union (AU) in 2006 provided over 75 per cent of all UN peacekeepers in Africa, as well as running their own operations.
