Providing an appropriate level of predictable and flexible humanitarian funding is not an optional extra for donors. All DAC donors have made – directly or indirectly – a commitment to the Principles and Good Practice of Humanitarian Donorship, which call for “funding in proportion to needs” (GHD principle 6, see Annex). There is currently no comprehensive, objective measure of global humanitarian need, complicating advocacy for more appropriate humanitarian funding levels. The closest approximation is the Consolidated Appeals process – and on average, 30% of the needs listed in these appeals go unfunded every year.
