As we count down to Human Rights Day commemorated annually on 21 March, we are acutely aware of the failures of the state to realise and satisfy the human rights enshrined in our Constitution and Bill of Rights, especially for children.
Since the dawn of democracy in South Africa in 1994 the country has struggled with a persistent high level of child malnutrition measured as stunting, when children are too short for their age.  This is not just shortness of height but it is a proxy for compromised health and a risk factor for lower cognitive development, lower education attainment and lower future productivity both in work output and in earning capabilities. Unhealthy children are likely to be our future unhealthy adults and compromised human development.

Protect children from hunger

It is for this reason that all efforts must be explored to protect children from hunger. Since the outbreak of the COVID-19 pandemic more than two years ago, there have been huge negative impacts on global health and development which are bearing down on the youngest members of the planet, our children. These impacts on children are costing their lives now and well into the future. South Africa has the largest social protection programme for children on the African continent with a child support grant that benefits more than 12 million children under the age of 18 years. On 23 February 2022, Finance Minister Enoch Godongwana announced that the child support grant would increase from R460 to R480 per month as from 1 April. A mere 4% increase, against a year-on-year food and non-alcoholic beverages inflation of 5.5%, rendering the already measly child support grant ineffective to keep hunger at bay, much less to address the nutrition that children need to grow and be healthy. In Section 28 of the Bill of Rights in our Constitution states that “every child has the right to basic nutrition, shelter, health care and social services, as well as the right to be protected from maltreatment, neglect, abuse or degradation”. But the high levels of child malnutrition, almost one in three children are stunted, while one in four households reported child hunger. This is a result of the failure to protect children.

One of South Africa’s leading civil society organisations, the Black Sash, undertook research with the South African Medical Research Council to explore how households receiving the child support grant managed with respect to food procurement and dietary patterns. I was approached to assist with child nutrition data interpretation and policy implications. It was not surprising to find that all 12 households included in this qualitative study were not able to cope or meet their food needs. These households’ food purchasing patterns were insufficient in quantity and in dietary quality. All household members were not able to eat regularly or sufficiently to keep hunger at bay. Even for children, hunger was a norm. Even for a household of a single mother and her five-year-old child, the child support grant was not enough to buy enough food, and other essentials like electricity, toiletries and cleaning materials. This was a huge cause for concern, given the context of COVID and the need to wash hands and surfaces regularly.

Trauma of  caregivers to provide food

The nutrition evaluation of the foods that were purchased was lacking in diversity, nutrient-density and low-quality foods, raising the issue of food safety as well. Poor households dependent on the child support grant, even with multiple grants, was not enough to buy enough food for all the household members. Many adults are forced to go without meals or reduce the amount of food they eat and to rely on food relief efforts like soup kitchens, food packs and food charity. The most heart-wrenching finding is the constant experience of trauma faced by caregivers to provide food for their hungry children. Caregivers expressed feelings of shame and guilt knowing that their children are hungry, for sending their children to ask for food from neighbours and community members. The constant cries for food would drive caregivers to ‘hit the children and send them to bed’. Sleeping is an escape from hunger and having to deal with hunger. These households are under severe psychological strain, re-emphasising that hungry people are angry people. This is not conducive for optimal child care and highlights hunger as a driver of child ‘maltreatment, neglect, abuse or degradation’ as listed in the Bill of Rights.

While caregivers are resourceful in trying to stretch the food budget by buying cheaper, smaller quantities of food products, giving small children many smaller snack foods and taking cash loans to buy foods, these efforts do not shield or protect children from the physical and psychological harm of hunger. A whole-of-society response is needed to create more provision efforts like community out-reach kitchens, food drives and donations, macro-policy initiatives to subsidise food for grant recipients, promotion and support of food gardens and to push government to institute a Basic Income Grant for unemployed persons 18-59 years of age. The child support grant is not enough to protect children from chronic hunger which itself is ‘maltreatment, neglect, abuse or degradation’ as enshrined in the South African Bill of Rights.

UFS venture cleans up acid mine drainage

The system that puts oxygen back into the water.

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
