To Western eyes, it may seem rather innappropriate to launch space programmes in sub-Saharan Africa, where nearly 70% of the population still lives on less $2 a day. Yet Joseph Akinyede, director of the African Regional Centre for Space Science and Technology Education in Nigeria, an education centre affiliated with the United Nations Office for Outer Space Affairs, says that the application of space science technology and research to “basic necessities” of life – health, education, energy, food security, environmental management – is critical for the development of the continent.
The 2010 Gates Foundation announcement of $1.5 billion for maternal health in developing countries over five years was welcomed, but it came heavily leveraged. Gates launched the Health in Africa Fund, through the International Finance Corporation (IFC), to establish new mechanisms to invest world health funding and national health budgets in private-sector healthcare facilities in Africa. The Gates Foundation's funding category for Global Maternal Health includes research and development in the US of technology and treatments, and also advocacy in vulnerable African nations for government policies. Since Gates believes sustainable health systems must be privately profitable, he leverages his "maternal health" funding to effectively divert investment of available in-country funds, as well as NGO funding, into private ventures that he favors, instead of into national health plans.
