The number of people infected by the coronavirus is linked to the density of urban living. South Africa’s townships and informal settlements are bearing the brunt of the disease, on top of all their existing problems of unemployment, poverty, hunger, and crime. This is a disturbing situation and demands greater attention across society.

This is according to Prof Ivan Turok from the Human Sciences Research Council (HSRC), the Department of Economics and Finance, and the Centre for Development Support at the University of the Free State (UFS), who has recently been awarded a Research Chair in City-Region Economies at the UFS by the South African Research Chairs Initiative (SARChI).

Prof Turok was part of a webinar discussion on ‘Urban Living Post-COVID-19’ with Dr Geci Karuri-Sebina – who manages the research programme at South African Cities Network and who has two decades’ experience working and publishing in the fields of urban development, innovation, and foresight – and Mr Thireshen Govender, architect and founder of UrbanWorks. They analysed how COVID-19 challenges urban living, social distancing, and the de-densification of cities as South Africa heads towards 70% of its population living in urban areas.

According to Prof Turok, urban density has been blamed for the spread of the virus. “The fear of people crowding together has caused negative reactions from government, from business, and from households. This is unlikely to be a short-lived, temporary phenomenon. It will be with us for some time to come.”

“The virus poses an ongoing risk to society, with the prospect of second and third waves taking hold. A lockdown could be re-imposed and further efforts could be made to enforce distancing and de-densification of cities, particularly our densest settlements,” said Prof Turok.

 

De-risking urban density

There was a simple but compelling idea at the heart of his presentation, which should also be “at the heart of a more effective and inclusive response to the pandemic”. At the moment, the government’s response to the crisis facing our poorest communities is uninspiring. “We need a more positive vision for the future than wearing masks and washing our hands.”

“We need to be bolder and more imaginative about de-risking urban density. In other words, making crowded neighbourhoods safer and more secure for people to live in. Density poses multiple risks to residents. How do we reduce these risks in ways that generate wider benefits, rather than business as usual – forcing people to change their behaviour and follow protocols?”

With reference to New York, which was severely affected by the virus, Prof Turok showed that it was not density per se that was the problem, but rather the type of density. The densest part of the city (Manhattan) was far less affected by the virus than poorer outlying communities. “This gives us a clue that more floor space in taller buildings helps to prevent crowding and makes density more liveable,” said Prof Turok.

The reality in South Africa is also different when you drill down and distinguish between different kinds of places. Big cities have been affected worse than towns and rural areas – in terms of the incidence of infections and the number of deaths. Within cities, there have been far more problems in the townships and informal settlements than in the suburbs. In Cape Town, for example, the southern and northern suburbs and the central city have been barely affected by the virus. However, infections have been very high on the Cape Flats, including Khayelitsha, Langa, Gugulethu, Philippi, and Mitchells Plain.

“Population densities in some of these areas are more than 100 times higher than in the affluent suburbs. The differences are very striking.”

“Incomes on the Cape Flats are also much lower than elsewhere in the city. So, there is a correspondence between density and the disease, unlike New York,” says Prof Turok.

All the discussions about the pandemic so far has focused on the negative aspects of urban density for the risk of transmission. This ignores all the benefits of dense urban living. Intense human interaction fosters learning and creativity, which raises productivity and innovation. Concentrated populations generate economies of scale in the provision of infrastructure and institutions such as universities. Cities give firms greater choice of workers and vice versa.

 

Pure population density and economic density

Prof Turok continued by saying that physical distancing can be socially and economically damaging. “Attempts to force people apart through de-densification undermine all kinds of personal networks, weaken the social fabric of communities, and erode the economic advantages of proximity that are so important for cities.”

“We need to understand that people crowding together in dense informal settlements is a symptom of something more fundamental, namely poverty. The pressure on land reflects the fact that low-income households can’t afford the space standards of middle- and upper-income groups. Forcing people apart (or to stay home) to reduce the risk of transmission just treats the symptoms of the problem. It cannot be a lasting solution. It doesn’t build resilience to confront the multiple challenges facing poor communities,” said Prof Turok.

A key part of a lasting solution can be summed up as building economic density. This involves increasing investment in two- or three-storey buildings to give people more living space and to free up land at ground-floor level to accommodate essential infrastructure and more public space for markets and social interaction. A better living and working environment would strengthen community resilience to public-health problems and promote all-round development. The idea of economic density offers a practical vision that can inspire hope in a better future, rather than the status quo of wearing masks in crowded places.

“We need to de-risk urban density through tangible investment, rather than forced distancing or dispersal. This will help to bring about far-reaching improvements to people’s lives in cities. At the moment, the lack of economic density in impoverished communities is a much bigger problem than excessive population densities.”

Serious intervention by parents is required to deal
with childhood obesity. Prof Louise van den Berg and
a group of final-year PhD students worked on a study
about the prevalence of obesity in six-year-olds in
South Africa.

If your child is overweight when they start school at the age of six, unless you do something about it at that point, the indications are they are going to be overweight teenagers and obese adults. This is according to University of the Free State’s Prof Louise van den Berg.

Evidence has shown that overweight children and teenagers have a greater risk of developing lifestyle diseases such as type 2 diabetes, hypertension and cardiovascular disease later in life, and dying prematurely.

Obesity is a global pandemic rapidly spreading among adults and children, in developed and developing countries alike.

Dr Van den Berg worked with Keagan Di Ascenzo, Maryke Ferreira, Monja-Marie Kok, Anneke Lauwrens, all PhD students with the Department of Nutrition and Dietetics, to conduct the study. Their research found that children who are overweight by the time they turn six should be screened for weight problems.

Why six-year-olds?
Children who are overweight between the ages of two and five are five times more likely to be overweight when they are 12. There are two periods in a normal life cycle when the body makes new fat cells. The first is in the uterus and the second is around the age of six. The second phase lasts from the age of six to puberty.

The study assessed the prevalence of obesity in six-year-olds as part of a campaign in South Africa to raise awareness of the problem among parents and educators.

A total of 99 children were chosen from seven schools in Mangaung, the capital city of Free State. The schools were chosen from quintile four and five schools, which when measured by their own resources and economic circumstances, are well resourced and serve largely middle-class and wealthy communities.

The children’s weight, height and waist circumference were measured and used to calculate a body mass index score and waist-to-height ratio. Both these figures are good predictors for future lifestyle disease risks such as type 2 diabetes, hypertension and cardiovascular disease. A person with a good waist-to-height ratio can wrap a piece of string equal to their height around their waist at least twice.

When the children had a higher body mass index, they also had an increased waist to height ratio. The study found one in four children from the schools surveyed were overweight when they started primary school.

Nipping the fat in the bud
Although there are many factors that play a role in preventing childhood obesity, parents’ perceptions of their children’s weight play an important role. A recent study found that more than 50% of parents underestimate the weight of their obese children. These parents remain unaware of the risks their children face and are not motivated to take any action.

At least half of the parents whose children are overweight struggle to recognise their children’s weight problems fearing that they will be labelled or stigmatised. By the time they turn six overweight children should be referred to dieticians and nutritionists who are qualified to guide their parents in getting them to eat well and be more physically active at pre-primary and primary school.

The high prevalence of weight problems among six-year-olds found in this study is an urgent call to healthcare professionals to step up and empower parents, educators and children with the necessary skills for healthy dietary practices and adequate physical activity.
