The report, based on surveys in 34 African countries, says :
This is true even in those countries that have never had term limits and those that have removed them in the past 15 years. Continuing efforts to dispense with term limits thus reveal a major disconnect between African leaders and African citizens on this issue, underlining the lingering legacy of big-man rule on the continent and highlighting the fragility of African democracies.
The report discusses  the term limit extension phenomenon in African politics:
At the end of the 20th century, many African countries adopted presidential term limits aspart (sic) of a broader set of constitutional rules that accompanied the transition from personal and authoritarian rule to pluralistic modes of governance. While term limits were widely embraced by the larger African public, these rules have in recent years come under increasing attack from incumbent presidents seeking to extend their tenures. In the first six months of 2015 alone, the presidents of Burundi, Benin, the Democratic Republic of Congo, and Rwanda have either personally or through their supporters expressed the intention to dispense with or circumvent term limits in order to seek additional terms of office.
These quests are often couched in language that portrays a leader’s desire for more time in office as a response to popular demands. A striking example was Blaise Compaoré’s 2014 attempt to seek a third term in Burkina Faso, which was stopped by popular protests that forced the president not just to back off, but to leave the country. But other leaders have been more successful in their efforts to avoid relinquishing power.
David Shinn, the former US ambassador to Burkina Faso and Ethiopia, says  the track record on term limits in African politics is “mixed”:
Early in 2008, thirty-three of sub-Saharan Africa’s forty-eight countries had constitutions that contained term limit provisions. Some African leaders have willingly turned over power in compliance with these constitutional requirements. They include recent, former leaders of Botswana, Benin, Cape Verde, Mali, Mozambique, Säo Tomé e Principe and Tanzania. Nelson Mandela in South Africa stepped down after one term. Jerry Rawlings of Ghana and Daniel arap Moi of Kenya complied with constitutional term limits under duress.
Several African leaders tried but failed to change the term limit provision of their constitution so that they could run again. Zambia’s Frederick Chiluba, Malawi’s Bakili Muluzi and Nigeria’s Olusegun Obasanjo ultimately bowed to the will of the political system and accepted term limits.
Other African incumbents managed to change the constitution so that they could have at least one additional term. Current or recent leaders in Burkina Faso, Chad, Gabon, Guinea, Namibia, Togo, Uganda and Algeria are among those who successfully changed term limit requirements in order to prolong their time in office. In 2008, Cameroon’s parliament eliminated the two-term (seven years per term) limit for Paul Biya. I served at the U.S. embassy in Yaounde when Biya first became president in 1982. He will be able to run again in 2011 after twenty-eight years as president. The president of Niger is currently trying to change the constitution so that he can run for a third term.
In total, 18 African countries  do not have presidential term limits. Sudan presents a unique case; although President Bashir has been in power since 1989, his reelection earlier this year—when he carried 94 percent of the vote—is technically only his second term in office, following the secession of South Sudan in 2011 after a national referendum.
During the Economic Community Of West African States (ECOWAS) meeting last month in Accra, Ghana, West African leaders dropped the idea of instituting a two-term limit on the presidency across the region, after The Gambia and Togo, the only member states without term limits, opposed the move . Internet users in West Africa were widely critical of the decision.
A conflict in Burundi continues today, sparked by President Pierre Nkurunziza ‘s bid for a third term . Riots have spread throughout the country in protest. The UN Secretary General Ban Kimoon has even called on Ugandan President Museveni to intervene. At an impromptu East African Community (EAC) meeting, former army general Godefroid Niyombare (who'd been suspended just a few months earlier) staged a coup in an attempt to oust Nkurunziza.
The events in Burundi and in other countries such as the Democratic Republic of Congo, Burkina Faso, and Rwanda have sustained a growing debate among Africans about term limits.
For example, in Uganda where voters face the same predicament of a president that is seeking a fifth term , netizens celebrated the coup in Burundi:

Many jokes were even made about the coup in Burundi. Allan Senyonga, a Ugandan journalist working in Rwanda, said:

Nkurunziza: God told me to stand for a ‘2nd term’ God: Don't use my name in vain if you can't even count properly. pic.twitter.com/A5RjbadFrc

Simon Kaheru surveyed readers about the best hashtags available to mock Nkurunziza:
Heartless as we may be, I've got to ask: what hashtag are people using to make fun of #Nkurunziza ?

As the cartoonist at the Daily Monitor created this:

The first President of Uganda, Dr. Milton Obote, was ousted in a manner similar to Niyombare's attempt, while delivering a speech at a Commonwealth meeting in Singapore in 1971.
Milton Obote must be in his grave laughing at Nkurunziza for never bothering to read about EAC history.

Benjamin Rukwenge expressed his mistrust of the East African presidents:

Denis Juuko condemned those who were celebrating the coup:
If you are celebrating the #BurundiCoup  you are an enemy of democracy

In Zimbabwe, where president Robert Mugabe has been in power since 1980, someone named Hungwe commented on a story in the New Zimbabwe, joking :
Minimum of 4 terms of course! One term to fill up personal pockets. Another term for the family. Another one for relatives and friends, and probably another one to look at national issues and avenues to stay in power.
Another Zimbabwean, “William Doctor,” asked :
Then why has the 2-term limit been so successful in the United States? And why is Africa such a dismal failure?
“Political Analyser,” apparently based in Zambia, simply advised :
Never accept that dictator to come for a third term
“Bants-a-nius Dante” warned:
These are bad times for Mugabe,Hayatou [Issa Hayatou is the president of the Confederation of African Football since 1988],Nkuruzinza and other sit tight leaders all over the world…

Another netizen argued that  the problem is not only with African presidents but also with “serial” opposition presidential candidates, like the ones in Zambia:
What else do you expect from HH [Haikainde Hichilema] 6 elections, Nawakwi 6, Nevers Mumba 2, please leave space for others you have suffered electoral nightmare and its enough.
However, commenting on a story about Rwandan President Paul Kagame, who said that he is open to leaving power, Abullah Omar wrote :
I do not understand this fixation of a term limit for an elected office.if the people opt for continuity why deny them their choice.
Professor Nshuti Manasseh expressed similar views :
But Rwandese want him to stay on to ensure stability and development of a very fragile country Rwanda is 21 years after genocide. So if Rwandese requests him to lead them for more than two term limits, isn't that democracy?
“Eng.Murenzi Daniel” thought Rwanda and Burundi presented very different third-term political scenarios:
“Leader”&”Dictator” Kagame FORCED by the people for a 3rd term (Leader) Nkuruzinza FORCING himself on the people for a 3rd term. (Dictator)

Raymond Maro, based in Tanzania, was more optimistic:
Tanzania was the first country in sub Saharan Africa to put Presidential term limit. By 2017 all African states should adopt this #DGTrends 
— Raymond C Maro (@RaymondCMaro) September 16, 2014 
Kenyan blogger Ken Opalo noted  that the record suggests presidents trying to extend their limits are more likely to succeed:
So what we see in the existing data is that conditional on *overtly* trying to scrap term limits African Heads of State are more likely to succeed than not (9 successes, 6 failures). However, this observation doesn’t tell us anything about the presidents who did not formally consider term limit extensions. For instance, in Kenya (Moi) and Ghana (Rawlings), presidents did not initiate formal debate on the subject but were widely rumored to have tried to do so. So it’s probably the case that presidents who are more likely to succeed self-select into formally initiating public debate on the subject of term limit extension, thereby tilting the balance. And if you factor in the countries that have had more than one episode of term-limited presidents stepping down, suddenly the odds look pretty good for the consolidation of the norm of term limits in Sub Saharan Africa.
He concluded on an optimistic note:
I wouldn’t rule out, in the next decade or so, the adoption of an African Union resolution (akin to the one against coups) that sanctions Heads of State who violate constitutional term limits.
