Is legacy the epicenter of president Obama's visit in Africa?

At the media briefing's Q&A organised for the visit of president Barack Obama in South Africa, following diplomatic presentations both presidents and an earlier meeting held at the Union Buildings (South Africa's government complex), a journalist stood up  and ask South Africa's president, Jacob Zuma, what he thinks would/ should be Obama's legacy in Africa.

President Zuma quipped diplomatically in his response that it is his principle not to pronounce on legacies of people who are still in office. He may have been witty in his response, but it is matter that he, and Obama himself, know is a point at issue for Barack Obama's remaining three and a half years in the White House. In fact, it is a desirable outcome, not only of South Africa, but the entire African continent for Obama to leave some kind of legacy in and for Africa given his emergence to presidential power in 2007 and his chronicled roots in Africa.

Obama has no choice but to rise to the occasion. Let me qualify this: Bill Clinton has AGOA. George W. Bush has PEPFAR and the MCC. So far, Barack Obama has made a start on food security, but nothing legacy-worthy yet. The Carnegie Centre for Global Development (CGD) has made it easy for Obama to begin crafting his legacy. CGD has suggested that Obama's focus should be on electricity/ or energy in general and thus culminate in some worthy course that would be his legacy. The think tank suggested three reasons why electricity should be Obama's legacy in Africa. I personally agree with CGD with no hesitation. As Obama searches for legacies in Africa, this should be one area that the policy makers at the White House need to pin their pens and thoughts on. The dire shortage of electricity in the African continent is a constraint for businesses and investments and as a result renders unproductive economic activities. So Mr. Obama, you now have some alternatives to chose from and develop for the next three and half years at least at a policy level. The next generation of American leaders will implement it for you. And that would be your legacy, at least in and for Africa. 

"The Meltdown Of The West": A Crucial Historical Juncture Upon Which Africa Should Take A Leapfrog

History is pregnant with lessons that African leaders should, once and for all, take leaf out of these lessons and perhaps turn a blind eye to economic growth hypotheses and economic development policies that never worked to rid the continent of its socioeconomic-ills. A simple strategic insight and taking a thorough stock of the current geopolitical shift and sway them to benefit Africa may be the right medicine at the right time. Lessons of how developed countries leaped out of critical junctures and historical contingencies when they were in the state of development are in abundance. Acemoglu and Robinsons, in their seminal book "Why Nations Fail" trace critical junctures from the fourteenth century outbreak of the bubonic plaque, the Black Death in 1346 to the England political revolution of 1688, the Glorious Revolution. They demostrate without any mathematical or complex economic model of how these critical junctures correlates to sustainable economic growth and prosperity. A critical juncture is a major confluence of factors disrupting the existing economic or political balance in society.
