In the next 35 years, the population in cities is estimated to expand by an additional 2.5 billion people, almost double the population of China. As a vital component for connectivity, public health, social welfare, and economic development, infrastructure in all its forms – basic, social, and economic – is critical for the anticipated urban growth. As a day to promote the international community’s interest in global urbanisation and contribute to sustainable development around the world, 31 October marks World Cities Day – where the spotlight on building sustainable cities comes to the fore.
“Globally, the annual investment required to cover the gap for resilient infrastructure is estimated at $4.5-$5.4 trillion,” says Riaan Graham, sales director for Ruckus Networks, sub-Saharan Africa. “And while no two cities are the same, more than than 50% of the global population – live in cities – and instrumental to achieving sustainable smart cities, is harnessing a new world of digital technology and communication to first enable a connected city.”
Building on connectivity
Connectivity is a foundational layer to Smart Cities, both for Internet access and new digital services. A great starting point for cities is to deploy public Wi-Fi. Continues Graham; “Public Wi-Fi is a great way to create a more vibrant community and also connect citizens, businesses and visitors. But the benefits of Wi-Fi don’t stop there. Cities are leveraging smart Wi-Fi for many applications that go well beyond free public access to the Internet such as e-routing traffic, monitoring air pollution, conserving water, improving public safety and encouraging more direct participation, interaction and collaboration with local government offered services.”
In fact, according to an IDC InfoBrief Smart City aspects such as networked LED street lighting can provide a 25-50% reduction in operations and energy costs, connected trash bins can yield more than 50% reduction in garbage collection costs, 20–30% cost reduction can be obtained with smart parking and smart water systems can save 40% less clean water loss due to leaks and burst pipes. Such aspects are key to building sustainable cities and managing resources and services.
Alison Groves, Regional Director, WSP, Building Services, Africa, agrees, but cautions that when planning, designing and building infrastructure within the African context, we need to be conscious that we are operating in spaces that sit at two extreme ends of the development cycle. “On one end, we have cities and urban centres that are faced with challenges to the maintaining the capacity of existing infrastructure networks. These nodes still boast long-term infrastructure planning, which includes introducing smart technologies into their city scape that will make these cities more connected, innovative and nimble in the face of future disruption. At the other end of the cycle, however, we have vast areas that are underdeveloped, geographically dispersed, remote, and with limited accessibility to-and-from the nearest urban node.”
Groves believes that to be able to support continued and future growth – of populations, industries and economies – long-term planning must be approached with a vision to compensate for both ends of the development cycle and everything in between. “As we look to build cities and spaces for rural communities that are liveable, resilient to disruptions, and futureproofed, sustainability is the way to get there.”
“Sustainability is a lens through which the planning, project delivery, and development processes focus to achieve the needs of the communities today without sacrificing capacity for future generations. A sustainability lens always includes balancing priorities across several areas, including the economy, community needs, and environmental quality, but also equity, health and well-being, energy, water and materials resources, and transportation and mobility needs,” adds Groves.
Resilience and liveability
Urbanisation, demographic shift, environmental changes and new technologies are reshaping the way city leaders are looking at sustainability as well as creating and delivering on public services to address these new dynamics, and the rise of Smart Cities is the response to these challenges. Smart cities will help address the economic and social inequality that this divide creates, by providing Internet access to all citizens.
“With robust networks in place, bridging this divide will help bring communities closer together and encourage citizens to play a more active role to local councils. Flawless connectivity will improve city infrastructure and make it possible for citizens to engage with their community, such as removing the roadblocks that complicate access to local services. We are already seeing significant foreign direct investment into such key ICT initiatives across the continent, but sustainability has to be at the heart of this if Africa is to create a resilient framework for better cities,” adds Graham.
“In Africa, resilience and liveability must be the desired outcomes sought through planning and design processes. Achieving these outcomes will require respecting and balancing local environmental, social, economic, and climate risk priorities through a robust planning and data-driven design process. And, ultimately the goal should be that we are building liveable spaces that are people-centric, integrated, connected, smart, nimble and resilient – where societies can thrive, well into the future,” concludes Groves.
Notre Dame, Scoop Makhathini, GoT, top week in search
From fire disaster to social media disaster, the top Google searches this week covered a wide gamut of themes.
Paris and the whole world looked on in shock as the 856-year-old medieval Catholic cathedral crumbled into ash. The tragic infernal destruction of this tourist attraction of historical and religious significance led South Africans to generate more than 200 000 search queries for “Notre Dame Cathedral” on Monday. Authorities are investigating the cause of the fire that razed the architectural icon.
In other top trending searches on Google this week, radio presenter Siyabonga Ngwekazi, AKA Scoop Makhathini, went viral when it appeared he had taken to Twitter to expose his girlfriend, Akhona Carpede, for cheating on him. Scoop has since come out to say that he was not responsible for the bitter rant and that his account was hacked. “Scoop Makhathini” generated more than 20 000 search queries on Wednesday.
Fans generated more than 20 000 search queries for “Sam Smith” on Tuesday ahead of the the British superstar’s Cape Town performance at the Grand West Casino. Smith ended up cutting his performance short that night due to vocal strain.
Local Game of Thrones superfans were beside themselves on Sunday, searching the internet high and low for the first episode of the American fantasy drama’s eighth season. “Game of Thrones, season 8, episode 1” generated more than 100 000 queries on Google Search on the weekend.
As the festivities kicked off in California with headliners such as Childish Gambino and Ariana Grande, South Africans generated more than 2 000 search queries for “Coachella” on Saturday.
South Africans generated more than 5 000 search queries for “Wendy Williams” on Friday as it emerged that the American talk show host had filed for divorce from her husband Kevin Hunter after 21 years of marriage. Hunter has long been rumored to have been cheating on Williams, which reportedly finally led to the divorce.
Search trends information is gleaned from data collated by Google based on what South Africans have been searching for and asking Google. Google processes more than 40 000 search queries every second. This translates to more than a billion searches per day and 1.2 trillion searches per year worldwide.

5G smartphones to hit 5M sales in 2019
According to the latest research from Strategy Analytics, global smartphone shipments will reach a modest 5 million units in 2019. Early 5G smartphone models will be expensive and available in limited volumes. Samsung, LG and Huawei will be the early 5G smartphone leaders this year, followed by Apple next year.
Ken Hyers, Director at Strategy Analytics, said, “We forecast global 5G smartphone shipments will reach a modest 5 million units in 2019. Less than 1 percent of all smartphones shipped worldwide will be 5G-enabled this year. Global 5G smartphone shipments are tiny for now, due to expensive device pricing, component bottlenecks, and restricted availability of active 5G networks.”
Ville Petteri-Ukonaho, senior analyst at Strategy Analytics, added, “Samsung will be the early 5G smartphone leader in the first half of 2019, due to initial launches across South Korea and the United States. We predict LG, Huawei, Xiaomi, Motorola and others will follow later in the year, followed by Apple iPhone with its first 5G model during the second half of 2020. The iPhone looks set to be at least a year behind Samsung in the 5G smartphone race and Apple must be careful not to fall too far behind.”
Neil Mawston, executive director at Strategy Analytics, added, “The short-term outlook for 5G smartphones is weak, but the long-term opportunity remains huge. We forecast 1 billion 5G smartphones to ship worldwide per year by 2025. The introduction of 5G networks, by carriers like Verizon or China Mobile, opens up high-speed, ultra-low-latency services such as 8K video, streaming games, and augmented reality for business. The next big question for the mobile industry is how much extra consumers are really willing to pay, if anything, for those emerging 5G smartphones and services.”
