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!

Her advice to farmers is that they should make sure they are aware of the total cost (investment and operating costs) of an irrigation system. In most cases the investment cost is low, but the operating cost over the lifetime of the system is high.

“It is very important to have a look at the total cost and to install the most economic system,” says Marcill Venter, lecturer at the University of the Free State (UFS), who has done research on the economic sustainability of water-pipe systems.

Irrigation systems important components for farming
This research comes at a time when many farmers are relying on their irrigation systems due to persistent drought and low rainfall during 2016. South Africa has also experienced an abnormal increase in electricity tariffs in recent years. Due to tariff increases which threaten the future profitability of irrigation producers, the Water Research Commission (WRC) has launched and financed a project on the sustainable management of irrigation farming systems. “I had the opportunity to work on the project as a researcher,” says Venter.

The heart of every irrigation system is the water pipes that bring life to crops and livestock, and this is what Venter’s research is about. “Water pipes are part of the whole design of irrigation systems. The design of the system impact certain factors which determine the investment and operating costs,” she says.

Mathematical system to help farmers
Venter and Professor Bennie Grové, also from the Department of Agricultural Economics at the UFS, designed the Soil Water Irrigation Planning and Energy Management (SWIP-E) programming model as part of the WRC’s project, as well as for her master’s degree. “The model determines irrigation pump hours through a daily groundwater budget, while also taking into account the time-of-use electricity tariff structure and change in kilowatt requirements arising from the main-line design,” says Venter. The model is a non-linear programming model programmed in General Algebraic Modeling System (GAMS).

Design of irrigation system important for sustainability

The main outcome of the study is that the time-of-use electricity tariff structure (Ruraflex) is always more profitable than the flat-rate structure (Landrate). The interaction between the management and design of a system is crucial, as it determines the investment and operating costs. Irrigation designers should take the investment and operating cost of a system into account during the design process. The standards set by the South African Irrigation Institute (SAII) should also be controlled and revised.

Water-pipe thickness plays major role in cost cuts
There is interaction between water-pipe thickness, investment and operating costs. When thinner water pipes are installed, it increases the friction in the system as well as the kilowatt usage. A high kilowatt increases the operating cost, but the use of thinner water pipes lowers the investment cost. Thicker water pipes therefore lower the friction and the kilowatt requirements, which leads to lower operating costs, but thicker pipes have a higher investment cost. “It is thus crucial to look at the total cost (operating and investment cost) when investing in a new system. Farmers should invest in the system with the lowest total cost,” says Venter.
