Post-2015, there will be a need for substantial increases in the concessional resource flows to low-income and lower-middle income countries, on a stable and predictable basis, to support productive investment and the provision of public goods. The 2005 Paris Declaration and the subsequent Accra Agenda for Action in 2008, along with the Busan Partnership for Effective Development Cooperation in 2011, are the clearest results of those efforts. Although not yet fully implemented, these agreements imply a certain rebalancing of the relationships between partners and donors.
