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!

Several industries in South Africa are currently producing hundreds of thousands of tons of carbon dioxide a year, which are released directly into the air. A typical family sedan doing around 10 000 km per year, is annually releasing more than one ton of carbon dioxide into the atmosphere.

The Inorganic Chemistry Research Group in the Department of Chemistry at the University of the Free State (UFS), in collaboration with the University of Zurich in Switzerland, has focused in recent years on using carbon dioxide – which is regarded as a harmful and global warming gas – in a meaningful way. 

According to Prof André Roodt, Head of Inorganic Chemistry at the UFS, the Department of Chemistry has for the past five decades been researching natural products that could be extracted from plants. These products are manufactured by plants through photosynthesis, in other words the utilisation of sunlight and carbon dioxide, nitrogen, and other nutrients from the soil.

Caffeine and chlorophyll 
“The Inorganic group is systematically researching the utilisation of carbon dioxide. Carbon dioxide is absorbed by plants through chlorophyll and used to make interesting and valuable compounds and sugars, which in turn could be used for the production of important new medicines,” says Prof Roodt.

Caffeine, a major energy enhancer, is also manufactured through photosynthesis in plants. It is commonly found in tea and coffee, but also (artificially added) in energy drinks. Because caffeine is a stimulant of the central nervous system and reduces fatigue and drowsiness, some people prefer decaffeinated coffee when enjoying this hot drink late at night. 

Removing caffeine from coffee could be expensive and time-consuming, but also environmentally unfriendly, because it involves the use of harmful and flammable liquids. Some of the Inorganic Group’s research focus areas include the use of carbon dioxide for the extraction of compounds, such as caffeine from plants. 

“Therefore, the research could lead to the availability of more decaffeinated coffee products. Although decaffeinated coffee is currently aromatic, we want to investigate further to ensure better quality flavours,” says Prof Roodt.

Another research aspect the team is focusing on is the use of carbon dioxide to extract chlorophyll from plants which have medicinal properties themselves. Chemical suppliers sell chlorophyll at R3 000 a gram. “In the process of investigating chlorophyll, our group discovered simpler techniques to comfortably extract larger quantities from green vegetables and other plants,” says Prof Roodt.

Medicines
In addition, the Inorganic Research Group is also looking to use carbon dioxide as a building block for more valuable compounds. Some of these compounds will be used in the Inorganic Group’s research focus on radiopharmaceutical products for the identification and possibly even the treatment of diseases such as certain cancers, tuberculosis, and malaria.
