The Stability Pact for South Eastern Europe has also provided support to such initiatives, in particular the Sava River cooperation. The ENVSEC Initiative, a joint effort of UNDP, UNEP, OSCE, UNECE and the Regional Environmental Center for CEE (with the North Atlantic Treaty Organisation as an associate member) develops and implements transboundary water cooperation projects. Cooperation on transboundary waters in Africa is supported through the Africa Action Plan, agreed by G8 leaders in 2002. In many subregions, including EECCA, the establishment of joint bodies and strengthening transboundary water cooperation are considered to be among the important tasks of the EU Water Initiative, a partnership initiated by the EU at the World Summit on Sustainable Development in Johannesburg in 2002.
