We also welcome the joint debate being held today under agenda item 33 , on causes of conflict and the promotion of durable peace and sustainable development in Africa , and under agenda item 41 ( a ) , on final review and appraisal of the implementation of the United Nations New Agenda for the Development of Africa in the 1990s ( UN-NADAF ) .
