Africa's urbanisation 'megatrend' needs to deliver growth, says report

More than half of all Africans are expected to live in cities by 2050, so policymakers must ensure this “megatrend” acts as a catalyst for development and growth, and does not result in millions of people eking out precarious existences in slums, according to the latest African Economic Outlook.
The (pdf), produced by the (AfDB), the and the , said authorities must create inclusive growth, jobs, better housing and social safety nets, and improve links with rural areas to boost development in urban areas, now home to about 472 million Africans.
“As two-thirds of the investments in urban infrastructure to 2050 have yet to be made, the scope is large for new, wide-ranging urban policies to turn African cities and towns into engines of sustainable structural transformation,” the report said. “In order to seize this ‘urbanisation dividend’, a number of bold policy reforms are necessary.”
In 1950, 14% of Africans lived in urban areas compared with 40% today. By the mid-2030s, half are expected to live in cities and towns, with the proportion peaking at 56% around 2050. To put this in a historical context, it took Europe 110 years to move from 15% urban dwellers in 1800 to 40% in 1910.
Many urban dwellers are young – more than (pdf) are under the age of 18.5 and 19% are aged between 15 and 24 years old.
Young people have been variously described as a or a potential . The report said nine out of 10 working young people in sub-Saharan Africa are poor or near poor, and yet the working-age urban population now supports more family members than comparative populations elsewhere.
Mario Pezzini, director of the , said urbanisation could drive development if there is simultaneous job creation and infrastructure investment.
“It is not possible to separate these issues … What we are really talking about is how do you create conditions and services, not only to provide a better quality of life, which is crucial, but also to create opportunities for economic development … If you don’t create infrastructure, the jobs will not be there,” he said.
African cities, unlike other , often fail to reap the benefits that come when firms and people locate near one another, he added.
“Particularly in , the problem is that you move people from rural areas to the cities and they remain in the same conditions … but now living in slums … If there are no advantages for people moving, urbanisation will not be synonymous with transformation.”
Despite a slowdown in growth after the of recent years, Pezzini said the window of opportunity to get urbanisation right had not yet closed, noting that African growth rates are still . But investment is needed to turn youthful urban populations into a resource, rather than a risk.
“How do you break this cycle of marginalisation, that is putting people outside the mainstream, transforming them into agents against change?” Pezzini said.
The report estimated that, on average, African countries would need to spend 5-7% of gross domestic product, or a minimum of $100bn a year, on public infrastructure.
For Pezzini, these funds could come from taxes, remittances and overseas development assistance, as well as foreign direct investment. Generally, tax collection levels are low in Africa, but could rise if fiscal reforms are implemented.
Last year, net financial flows to Africa were estimated at $208bn, 1.8% lower than in 2014, but remittances increased by 1.2% to to $64bn. Official development assistance rose by 4% to $56bn.
“ can be leveraged to spur investment and growth, but efforts to maximise their development impact face major obstacles. And recent developments in the resource-rich countries of the Middle East and Russia and the relative stagnation of EU growth suggest that remittances will slow,” the report said.
Under – the ambitious global blueprint for development adopted at the UN last year – countries have committed to make cities and human settlements inclusive, safe, resilient and sustainable, with targets relating to safe and affordable housing and transport.
Pezzini said this commitment is critical not least because it recognises that development must be measured by targets other than GDP growth, and reflects the fact that inequalities and challenges exist in cities in the developing and developed world.
He said there is no silver bullet to deliver efficient urbanisation.
“What matters is policies and strategies. That’s what will make the difference. Why do you have some areas and regions where things work and others not? Policies matter. You may have certain conditions, but you can build on them or not, and that depends on the policies and institutions you create.”
