Insufficient funding for maternal health has been identified as a major obstacle in achieving MDG5, so the MHTF commissioned Global Heath Visions to conduct a landscaping of all the existing and potential maternal health donors based in the US. Some experts have called for a new maternal health donor affinity group, and this landscaping explored that feasibility. As global advocacy and activism for improved maternal health outcomes accelerates, so should funding. But this report found that is not the case, at least in the US. Further explorations into non-US funding for maternal health might yield more encouraging results. The report of the GHV landscaping exercise is found here, along with some annexes that identity specific activities and portfolios of current and potential MH donors.
