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.

Studies to reveal correlation between terrain, energy use, and giraffe locomotion
2016-11-18



More than half of giraffes in captivity in Europe are afflicted by lameness. This high prevalence represents an important welfare issue, similar to other large zoo animals.

According to Dr Chris Basu, a veterinarian at the Royal Veterinary College in the UK, giraffes in captivity are often afflicted by overgrown hooves, laminitis and joint problems. Diagnosis and treatment is limited by our understanding of anatomy and function, more specifically the locomotion of these animals. Although the giraffe is such a well-known and iconic animal, relatively little has been studied about their locomotor behaviour.

Dr Basu recently visited South Africa to do fieldwork on the locomotion of giraffes as part of his PhD studies under the mentorship of world-renowned Professor of Evolutionary Biomechanics, Prof John Hutchinson. This project is a joint venture between Dr Basu and Dr Francois Deacon, researcher in the Department of Animal, Wildlife, and Grassland Sciences at the UFS. Dr Deacon is a specialist in giraffe habitat-related research. 

Together Prof Hutchinson and Drs Deacon and Basu form a research group, working on studies about giraffe locomotion.

Wild giraffe population decrease by 40% in past decade

“Locomotion is one of the most common animal behaviours and comes with a significant daily energetic cost. Studying locomotion of wild animals aids us in making estimates of this energetic cost. Such estimates are useful in understanding how giraffes fit into ecosystems. Future conservation efforts will be influenced by knowledge of the energy demands in giraffes.

“Understanding aspects of giraffe locomotion also helps us to understand the relationships between anatomy, function and evolution. This is relevant to our basic understanding of the natural world, as well as to conservation and veterinary issues,” said Dr Deacon.

Locomotion study brings strategy for specialist foot care

On face value it seems as if foot disease pathologies are more common in zoo giraffes than in wild giraffes. “However, we need a good sample of data from both populations to prove this assumption,” said Dr Basu. 

This phenomenon is not well understood at the moment, but it’s thought that diet, substrate (e.g. concrete, straw, sand and grass) and genetics play a part in foot disease in giraffes. “Understanding how the feet are mechanically loaded during common activities (standing, walking, running) gives our research group ideas of where the highest strains occur, and later how these can be reduced through corrective foot trimming,” said Dr Basu.

Through the studies on giraffe locomotion, the research group plans to devise strategies for corrective foot trimming. At the moment, foot trimming is done with the best evidence available, which is extrapolation from closely related animals such as cattle. “But we know that giraffes’ specialist anatomy will likely demand specialist foot care,” Dr Basu said.

Studying giraffes in smaller versus larger spaces

The research group has begun to study the biomechanics of giraffe walking by looking at the kinematics (the movement) and the kinetics (the forces involved in movement) during walking strides. For this he studied adult giraffes at three zoological parks in the UK. 

However, due to the close proximity of fencing and buildings, it is not practical to study fast speeds in a zoo setting. 

A setting such as the Willem Pretorius Nature Reserve, near Ventersburg in the Free State, Kwaggafontein Nature Reserve, near Colesberg in the Karoo, and the Woodland Hills Wildlife Estate in Bloemfontein are all ideal for studying crucial aspects such as “faster than walking” speeds and gaits to measure key parameters (such as stride length, step frequency and stride duration). These studies are important to understand how giraffe form and function are adapted to their full range of locomotor behaviours. It also helps to comprehend the limits on athletic capacity in giraffes and how these compare to other animals. 

Drones open up unique opportunities for studying giraffes

The increasing availability of unmanned aerial vehicles (UAVs)/drones opens up unique opportunities for studying locomotion in animals like giraffes. Cameras mounted onto remotely controlled UAVs are a straightforward way to obtain high-quality video footage of giraffes while they run at different speeds.

“Using two UAVs, we have collected high definition slow motion video footage of galloping giraffes from three locations in the Free State. We have also collected detailed information about the terrain that the giraffes walked and ran across. From this we have created 3D maps of the ground. These maps will be used to examine the preferred terrain types for giraffes, and to see how different terrains affect their locomotion and energy use,” said Dr Deacon.

“The raw data (videos) will be digitised to obtain the stride parameters and limb angles of the animals. Later this will be combined with anatomical data and an estimation of limb forces to estimate the power output of the limbs and how that changes between different terrains,” said Dr Basu.
