A decade ago, Rob Nixon, a professor in the humanities and environment studies at Princeton University in the US, introduced the concept of slow violence in the context of climate change and environmentalism, explaining slow violence as violence that occurs gradually and out of sight, a violence of delayed destruction that is dispersed across time and space, an attritional violence that is typically not viewed as violence, at all. While profound, Professor Nixon’s concept of ”out-of-sight violence” and ”violence of delayed destruction” was challenged by Professor Thom Davies from the University of Nottingham in the UK who urged scholars to instead ask the question: ”out of sight to whom?” He argued that structural inequality mutated into noxious instances of immediate slow but pervasive violence by those who have endured toxic landscapes and unhealthy physical environments.

Reflecting on the impact of COVID-19 in the context of persistent hunger in South Africa’s cities, Dr Gareth Haysom from the University of Cape Town, challenged us as society to recognise the ”slow violence“ of hunger and food insecurity that are also often “experienced in private, incremental and accretive ways that are often invisible”. But as urged by Professor Davies, the question of child hunger and malnutrition in South Africa is really, to whom is this hunger and malnutrition invisible?

Malnutrition and its debilitating consequences have been studied and known about as far back as the 1950s. In 1976, Stoch and Smyth from the then Child Psychiatric Unit and Department of Paediatrics and Child Health at the University of Cape Town reported on a 15-year developmental study conducted from 1955 to 1970 on the effects of severe undernutrition during infancy on subsequent physical growth and intellectual functioning on coloured children from the Cape Flats concluded that the effects of severe undernutrition during infancy on subsequent brain growth and intellectual development confirmed gross retardation of intellect in the undernourished group when compared to the controls. Furthermore, the study concluded that given the abnormal performance of the control group that there was much evidence to suggest that the controls were also suboptimal in terms of nutritional status and intellectual functioning. This means that in general the nutritional status of coloured children on the Cape Flats was poor. Fast forward to 2021, and child nutrition in South Africa is still sub-optimal.

South Africa’s nutrition indicators have worsened

The most recent data from 2016 National Demographic Health Survey showed that 27% of children under the age of five years are stunted or too short for their age. This equates to more than 1.5 million children whose health and development is compromised and who have a lower chance of reaching their full potential even into their adult years. While many countries of the same economic development status have improved their nutrition indicators, South Africa’s nutrition indicators have worsened. South Africa has been identified as one of the countries with high levels of multiple forms of malnutrition manifested in high levels of stunting, childhood obesity and multiple micronutrient deficiencies, the most notable being vitamin A deficiency. These multiple forms of malnutrition cast a long shadow of ill-health and delayed development. of children, robbing them of quality of life and years of life in their childhood and their adult years. Malnutrition has a double cost on quality of life and additional health costs consuming resources that could have been spent on better food.

The right to have access to sufficient food is embedded in Section 26 and 27 of our Constitution and the right to adequate nutrition for children is stipulated in section 28. The Bill of Rights enshrined in the Constitution states that “every citizen has a right to have access to sufficient food, water and social security” and that “the State must take reasonable legislative and other measures, within its available resources, to achieve the progressive realisation of this right”. Before the onslaught of COVID-19, we as health and social care professionals, have been acutely aware that a significant number of South Africans do not have access to sufficient food and go hungry on a daily basis. Malnutrition is well-documented in South Africa and unfortunately is progressively getting worse.

SA has not prioritised children or the realisation of their human rights to food and nutrition

Better nutrition can only be achieved when food and care are available to young children but in the context of rising food prices, limited maternal support and a difficult psychosocial environment, mothers are not able to provide their children with a health-enabling environment. Our high levels of stunting and obesity levels reflect the chronic situation of poor-quality and inadequate diets coupled with poor caring practices. While these poor dietary practices are often individualised and focused on mothers, there are many systemic and structural barriers for families to access affordable and nutritious diets. The food environment is shaped by a profit-centred food system that comes at the cost of people’s health and well-being. Children have always being the prime focus of the food industry, from the promotion of maternal supplements to improved maternal nutrition for the developing foetus, to the promotion of infant formula as a convenient and easy-to-use alternative to breastfeeding, to the manipulative marketing of foods for and to children.

Child nutrition has become a global tracking indicator for both human and economic development. Sadly, our lack of progress over the past 20 years clearly illustrates that we, as a country, have not prioritised children or the realisation of their human rights to food and nutrition. The findings of the 2020 Child Gauge gives us, as a country, the opportunity to stop the violations of children’s rights and to end the slow violence of child malnutrition.

Research on cactus pear grabs attention of food, cosmetic and medical industry

The dedicated research and development programme at the UFS on spineless cactus pear (Opuntia ficus-indica) – also known as prickly pear – has grown steadily in both vision and dimension during the past 15 years. Formal cactus pear research at the UFS started with the formation of the Prickly Pear Working Group (PPWG) in June 2002. It has since gone from strength to strength with several MSc dissertations and a PhD thesis as well as popular and scientific publications flowing from this initiative.

According to Prof Wijnand Swart from the Department of Plant Sciences, the UFS is today recognised as a leading institution in the world conducting multi-disciplinary research on spineless cactus pear.

Cactus pear for animal feed

Increasing demands on already scarce water resources in South Africa require alternative sources of animal feed – specifically crops that are more efficient users of water. One alternative with the potential for widespread production is spineless cactus pear. It is 1.14 x more efficient in its use of water than Old man saltbush, 2.8 x more efficient than wheat, 3.75 x more efficient than lucerne and 7.5 x more efficient than rangeland vegetation.

“Studies on the use of sun-dried cactus pear cladodes suggest that it has the potential to provide some 25% of the basic feed resources required by South Africa’s commercial ruminant feed manufacturing sector,” says Prof HO de Waal of the Department of Animal, Wildlife and Grassland Sciences at the UFS.

Until recently, research has focused extensively on the use of cactus pear as drought fodder. However, this is now beginning to shift, with growing interest in the intensive production of spineless cactus pear for other types of animal feed. One example is the spineless cactus pear fruit, produced seasonal, yielding large quantities of fruit in a relatively short period of a few months in summer. Unless kept in cold storage, the fruit cannot be stored for a long period. Therefore, a procedure was developed to combine large volumes of mashed cactus pear fruit with dry hay and straw and preserve it for longer periods as high moisture livestock feed, kuilmoes – a high water content livestock feed similar to silage.

Cactus pear for human consumption

“In addition to its use as a livestock feed, cactus pear is increasingly being cultivated for human consumption. Although the plant can be consumed fresh as a juice or vegetable, significant value can be added through processing. This potential is considerable: the plant can be pickled; preserved as a jam or marmalade; or dried and milled to produce baking flour. It can also serve as a replacement of egg and fat in mayonnaise,” said Dr Maryna de Wit from the Department of Microbial, Biochemical and Food Biotechnology.

The extraction of mucilage from fresh cladodes can form a gelling, emulsifier, and fat-replacing agent commonly found in food products such as mayonnaise and candy. During an information session to the media Dr De Wit and her team conducted a food demonstration to showcase the use of the cladodes in a juice, chicken stir-fry, biscuits and a salad.

The extrusion of cactus pear seed oil provides a further lucrative niche product to the array of uses. These include high-value organic oil for the cosmetic sector, such as soap, hair gel and sun screens.

The cladodes and the fruit also have medicinal uses. It has anti-viral, anti-inflammatory, pain killing and anti-diabetic agents. It is also high in fibre and can lower cholesterol. The fruit also prevents proliferation of cells and suppresses tumour growth and can even help to reduce a hangover.

In South Africa the outdated perception of cactus pears as thorny, alien invaders, is rapidly disappearing. Instead, farmers now recognise that cactus pear can play a vital role as a high yielding, water-efficient, multi-use crop, said Prof de Waal and the members of the Cactus Pear Team.
