More than half of the world’s population now live in urban areas, many of them in low- and low-middle-income countries with limited ability to support urban growth. Urban areas are inherently fragile. Many cities are desperately overcrowded, with poor building construction, limited access, poor or absent waste disposal, limited or no access to clean water, irregular supplies of food, unreliable power supplies, inadequate emergency services, and problems with crime and violence. Healthcare is often poor or absent, with an increased risk of communicable disease outbreaks. Supply chains can easily be interrupted. Urban poverty and slums are proliferating with informal dwellings in areas vulnerable to natural disasters. The nature of urban areas can increase the impact of disasters, as was shown by the impact of the COVID-19 pandemic.
The pace of urbanisation across sub-Saharan Africa over the last 60 years is without precedence. In 1950, most African countries were agrarian societies and just over a quarter of the population lived in cities. By 2020, the continent had 74 cities with a population of more than one million people, equivalent to the US and Europe combined. Today almost half of sub-Saharan Africans are urban dwellers and by 2050 that number is projected to reach 60 per cent. That means two- thirds of the continent’s projected population growth over the next three decades – an additional 950 million people – will be absorbed by the region’s humming, thriving, bustling megacities. And, as the OECD notes, ‘this transition is profoundly transforming the social, economic and political geography of the continent.’ Lagos, with a population of more than 20 million and economy bigger than that of Kenya is a vast, energetic and flourishing metropolis, a centre of opportunity that is enabling young Nigerians to be wealthier, more open-minded and more cosmopolitan than any before it.
Lagos has undergone a cultural transformation in the last decade. Driven by its vast youth population, its creative industries, from art and design to music, film and fashion, are booming. Vogue magazine hails the city as West Africa’s cultural capital, and Nigeria’s music and entertainment industries stand to be its greatest export. And for this young generation of creatives, the Global North no longer resonates as the key tastemaker. As citizens of a boundless world they blend heritage with Western influences but remain deeply rooted in their African culture and express a growing confidence and pride in Africa and African identity.

The effectiveness of air traffic restriction in containing the spread of infectious diseases is full of controversy in prior literature. In January 2020, the Civil Aviation Administration of China (CAAC) announced air traffic restriction in response to the coronavirus disease (COVID-19) pandemic. This study’s aim is to empirically examine the policy effectiveness.
Method:
The data from 2 third-party platforms are used in this investigation. The COVID-19 data from the platform DXY and the air traffic data from Airsavvi are matched to each other. The robust panel regression with controlling city effect and time effect is conducted.
Results:
The curvilinear relations are found between the air traffic restriction and the existing cases, and the recovery rate (quadratic term = 9.006 and −0.967, respectively). As the strength of air traffic restriction is growing, the negative effect (-8.146) of air traffic restriction on the existing cases and the positive effect (0.961) of air traffic restriction on the recovery rate, respectively, begin decreasing.
Conclusion:
On the macro level, the air traffic restriction may help alleviate the growth of existing cases and help raise the recovery rate of COVID-19 in megacities of China, but both these effects will marginally recede as the restriction strength is intensifying.
