As the leaders of the world's eight richest countries prepare for a meeting this July in Scotland, they will find the pieces are finally in place to do something that just a decade ago might have been dismissed as a well-intentioned but naive endeavour: To put an end to the crushing poverty that is at the root of Africa's economic and political instability.
The G8 helped set the stage for success five years ago by endorsing a series of Millennium Development Goals that pledged to substantially reduce poverty in the developing world by 2015, with Africa as a key focus on the effort.
African leaders have responded with an impressive commitment to pursue economic and political reforms.
There have been bold statements on all sides. But the clock is ticking. When the G8 meets next month, the world is right to expect bold action.
A critical test for the G8 is whether it takes advantage of what many view as an opportunity for a quick win, providing the resources to expand proven solutions for reducing the crushing burden of disease that is a major contributor to Africa's perpetual political and economic frailty, and so much of its deep poverty.
Every year millions of Africans suffer and die of diseases that don't kill many people in rich countries. Among children under the age of five, death comes at a rate of one every three seconds, as they succumb to diseases such as rotavirus, pneumococcal disease and malaria, which in developed countries are prevented with routine vaccines, treated with easily available medicines, or kept under control.
These diseases do more than inflict human misery in Africa. They cause such a drain on resources and productivity that they damage the entire economy.
For example, there are estimates that if rich countries had done in Africa what they did for themselves eliminate malaria annual GDP would be US$100 billion more than it is today. Even a mere 10 per cent drop in malaria infections could provide a 0.3 per cent increase in GDP.
Imagine what a greater reduction in malaria and other debilitating afflictions could bring?
The good news is that much of the hard work to fight these diseases in Africa has already been done. Over the last few years, thanks to the diligent efforts of a number of public and private players, solutions are in place or in the pipeline that could give Africans the same health security now taken for granted in rich countries.
For example, efforts by the Global Alliance for Vaccines and Immunization and its partner, the Vaccine Fund, have saved more than 670,000 lives by helping countries immunize children against Hib disease, pertussis and hepatitis B.
Meanwhile, programmes to develop new drugs and vaccines for diseases that now mainly affect Africans, such as malaria, rotavirus and pneumococcal disease, have recently produced promising results.
The bottom line is that the international community has an opportunity to make a big difference in Africa by providing the resources to expand programmes known to be successful, and to accelerate research that is already very close to providing powerful new interventions.
No one is saying that any of these solutions will be cheap. But here again, new mechanisms are in place and require urgent donor support. At their July meeting, G8 leaders will have the opportunity to create what is being called the International Finance Facility for Immunization (IFFIm). It would help donor countries provide immediate financing for health assistance to African nations by selling bonds on international capital markets that are backed by donor commitments.
Leading voices in Africa say Africans are ready to do their part. For example, Nelson Mandela, both as an individual and through his Nelson Mandela Foundation, has pointed to fighting disease as an area where aid can have the greatest impact. In the last five years we have seen the Millennium Development Goals become a mainstream phenomenon. Today, we have an exciting convergence of proven solutions and the popular support that add a new dimension to our partnership with the suffering people of Africa.
The G8 and all developed countries have now an unprecedented opportunity to commit the resources required to fight the global health crisis and other debilitating problems that affect Africa. We are right to expect that the leaders of our most prosperous countries will seize this opportunity and emerge from their summit ready to invest aggressively in Africa.
