On 26 March 2020, the President declared a national lockdown in response to the COVID-19 pandemic as it started to emerge in South Africa. Since then and several weeks into the lockdown, Statistics South Africa (2020) has provided evidence which many intuitively knew would be more devastating to households than the coronavirus itself – loss of income and the negative effects that follow hunger. Stats SA reported that the percentage of respondents receiving no income increased from 5,2% before the lockdown to 15,4% by the sixth week of the national lockdown. Given that the majority of South Africans depend on the informal labour market, such as informal traders and casual workers, this lack of income would hit millions of households. Furthermore, Stats SA also reported a decrease in formal wage/salary earners for the same period, from 76,6% before the national lockdown to 66,7% by the sixth week of national lockdown.

While South Africa is food secure at national level, millions of households are food insecure. According to the United Nations Food and Agriculture Organization’s (FAO) 1996 definition of food security, this simply means that there is not enough food at all times for all the people in a household to have physical and economic access to sufficient, safe, and nutritious food that meets their dietary needs and food preferences for an active and healthy life.  In short, people are hungry and at greater risk for ill health – physically, emotionally, and spiritually.  A hungry man is an angry man. Likewise, a hungry nation is an angry nation.

In July 2019, the measurement of extreme poverty – the food poverty line (FPL) – was raised to R561 (using April 2019 prices) per person per month, which was up from R547 last year. This is the amount of money that Stats SA calculates an individual requires “to afford the minimum required daily energy intake” of 2 100 calories per day. Before the onset of the COVID-19 pandemic, South Africa already had a precarious food and nutrition situation, especially for young children. South Africa’s child stunting levels – an indication of chronic and long-term food insecurity – increased from 21% in 2008 to 27% in 2016.  With COVID-19 and the subsequent lockdown, child malnutrition rates are expected to increase. Stunting not only affects a child’s health, making them more susceptible to disease and infection, but also impairs their mental and physical development – meaning that children who suffer from stunting are less likely to achieve their full height and cognitive potentials as adults.  

What can we do to address this food situation or prevent it from worsening?
The 2020 Global Nutrition Report recognises and asserts that inequality and globalisation are major drivers of food insecurity. As individuals and as collectives, we need to continue to advocate for and support calls to continue raising the child support grant to help households stay above the poverty line.  Millions of households in South Africa are supported by social grants; in solidarity, we need to appreciate the safety net that these social grants provide to vulnerable households. Advocate for and support initiatives to safeguard child health and nutrition, including efforts to promote, protect, and support breastfeeding in neonatal care, postnatal care, and ongoing support to breastfeeding mothers.  Breastfeeding remains the most cost-effective health intervention for infants and young children, supporting optimal growth and development and providing long-term health benefits into adulthood. Advocate for and support initiatives to coordinate sustainable food support to vulnerable households, including, among others, food distribution, food vouchers, onsite feeding, home gardening, and tax-free food baskets.  These efforts would be our collective solidarity to support and protect vulnerable households as we enter the global economic recession as a result of COVID-19.

How can we protect our households’ food and nutrition security? 
COVID-19 brings with it much uncertainty and many unintended negative effects.  While we seek out strategies to support mental well-being and emotional resilience, we also need to remain physically healthy.  Good nutrition is fundamental to good health and well-being. South Africa has a set of ten healthy eating guidelines that promote the principles of eating more unprocessed foods, eating more vegetables and fruit, reducing the use of fats and oils and reducing the intake of sugar and salt.  Good nutrition starts with good food and sometimes good food can cost more, so it is important to use your food budget wisely.  The food budget includes food eaten at home, as well as funds spent on food eaten outside of the home, eating take-outs, foods bought online, and food eaten away from home.  Planning your meals in advance and sticking to a food plan will limit opportunities to spend money on items that are not on the plan; planning ahead also means you can take advantage of good prices, especially as food prices are on the increase and will continue to increase. Bulking up when prices are low and on special, making use of combo buying, e.g. buy three and pay for two, and buying directly from food producers such as co-ops, all help to save money in the long run.  Meat, fish, and especially seafood are the most expensive food items; rather use eggs, chicken, and less expense meat cuts for your meals.  Legumes such as dried beans, peas, and soya are less expensive with great nutritional value.  Explore these less-known group of foods with many great health benefits, such as no fat, more fibre, and lots of vitamins and minerals.

In an effort to eat more fresh vegetables and fruit, starting a home garden is a great family challenge and a definite way of keeping food costs low. And as we navigate the new normal post-COVID times ahead, let us keep mealtimes and meal preparation a fun family activity. Discovering new foods and new tastes can be as exciting as travelling to a new place.  Stay safe, stay healthy!

Eye tracker device a first in Africa
2013-07-31

Keeping an eye on empowerment

"If we can see what you see, we can think what you think."

Eye-tracking used to be one of those fabulous science-fiction inventions, along with Superman-like bionic ability. Could you really use the movement of your eyes to read people's minds? Or drive your car? Or transfix your enemy with a laser-beam?

Well, actually, yes, you can (apart, perhaps, from the laser beam… ). An eye tracker is not something from science fiction; it actually exists, and is widely used around the world for a number of purposes.

Simply put, an eye tracker is a device for measuring eye positions and eye movement. Its most obvious use is in marketing, to find out what people are looking at (when they see an advertisement, for instance, or when they are wandering along a supermarket aisle). The eye tracker measures where people look first, what attracts their attention, and what they look at the longest. It is used extensively in developed countries to predict consumer behaviour, based on what – literally – catches the eye.

On a more serious level, psychologists, therapists and educators can also use this device for a number of applications, such as analysis and education. And – most excitingly – eye tracking can be used by disabled people to use a computer and thereby operate a number of devices and machines. Impaired or disabled people can use eye tracking to get a whole new lease on life.

In South Africa and other developing countries, however, eye tracking is not widely used. Even though off-the-shelf webcams and open-source software can be obtained extremely cheaply, they are complex to use and the quality cannot be guaranteed. Specialist high-quality eye-tracking devices have to be imported, and they are extremely expensive – or rather – they used to be. Not anymore.

The Department of Computer Science and Informatics (CSI) at the University of the Free State has succeeded in developing a high-quality eye tracker at a fraction of the cost of the imported devices. Along with the hardware, the department has also developed specialised software for a number of applications. These would be useful for graphic designers, marketers, analysts, cognitive psychologists, language specialists, ophthalmologists, radiographers, occupational and speech therapists, and people with disabilities. In the not-too-distant future, even fleet owners and drivers would be able to use this technology.

"The research team at CSI has many years of eye-tracking experience," says team leader Prof Pieter Blignaut, "both with the technical aspect as well as the practical aspect. We also provide a multi-dimensional service to clients that includes the equipment, training and support. We even provide feedback to users.

"We have a basic desktop model available that can be used for research, and can be adapted so that people can interact with a computer. It will be possible in future to design a device that would be able to operate a wheelchair. We are working on a model incorporated into a pair of glasses which will provide gaze analysis for people in their natural surroundings, for instance when driving a vehicle.

"Up till now, the imported models have been too expensive," he continues. "But with our system, the technology is now within reach for anyone who needs it. This could lead to economic expansion and job creation."

The University of the Free State is the first manufacturer of eye-tracking devices in Africa, and Blignaut hopes that the project will contribute to nation-building and empowerment.

"The biggest advantage is that we now have a local manufacturer providing a quality product with local training and support."

In an eye-tracking device, a tiny infra-red light shines on the eye and causes a reflection which is picked up by a high-resolution camera. Every eye movement causes a change in the reflection, which is then mapped. Infra-red light is not harmful to the eye and is not even noticed. Eye movement is then completely natural.

Based on eye movements, a researcher can study cognitive patterns, driver behaviour, attention spans, even thinking patterns. A disabled person could use their eye-movements to interact with a computer, with future technology (still in development) that would enable that computer to control a wheelchair or operate machinery.

The UFS recently initiated the foundation of an eye-tracking interest group for South Africa (ETSA) and sponsor a biennial-eye tracking conference. Their website can be found at www.eyetrackingsa.co.za.

“Eye tracking is an amazing tool for empowerment and development in Africa, “ says Blignaut, “but it is not used as much as it should be, because it is seen as too expensive. We are trying to bring this technology within the reach of anyone and everyone who needs it.”
