And in these success stories, effective partnership between the United Nations (UN) system and OECD members has been instrumental. And what is equally important, by underpinning technical and policy assistance, ODA strengthens the capacities of national governments and civil society to put in place systems that enable them to plan, budget, implement and monitor progress towards development results. These efforts are based on the principles outlined in the 2005 Paris Declaration on Aid Effectiveness, which were given added impetus at the Third High Level Forum on Aid Effectiveness in Accra, Ghana (2008), through the Accra Agenda for Action.
