A side-event on predictability of health aid offered a qualitative contribution to the debate on this central dimension of aid effectiveness. The discussion built on a set of documents, in particular the OECD study on
donor practices on forward planning of aid expenditures and a study commissioned by the WHO on the “Donors constraints to provide long-term health aid”. The discussion illustrated why aid is currently un-predictable, the difficulties that derive from this for planning and budgeting in countries, the real blockages for making aid more predictable, the promising ways to make health aid to countries more predictable (Innovative Finance Facility for Immunisation, International Health Partnership+), the options for increased spending for health including for health personal, the contribution of results-based financing to longer-term funding and use of country systems.
