What does it mean to say one has a right to something, such as access to housing or to protest or to property? What are human rights? What do they ‘do’?

One often hears of human rights being asserted as if they give one an absolute claim to something specific and discrete, which can be enforced against anything and everyone else, irrespective of the impact on the interests (and rights) of others, as well as broader public goals or values.

Perhaps the clearest example of this was the way in which the right to ownership of land was understood under apartheid property law. Ownership then was an absolutely exclusive right: it entitled its holders to exclude everyone else without a countervailing right from their land, irrespective of circumstance or context. All a landowner had to prove before a court to obtain an eviction order if they sought to evict someone from their land, was that they had the right (owned the land) and that those they sought to evict had no countervailing right in law to be on the land. If the right was proved in this way, the remedy of exclusion through eviction followed automatically – the court had to grant the eviction order.

Constitutional right to peaceful protest

A more recent example of this view was on display in the way in which members of parliament complained about their removal from the house when they attempted to shut down the President’s State of the Nation Address through protest action. Many responded by saying their removal was unjustified because, by trying to stop the address from proceeding, they were exercising their constitutional right to peaceful protest. The assumption underlying this response is that the right to protest peacefully and unarmed entitles you to protest peacefully and unarmed in any way you see fit and regardless of the consequences for other people and for society at large.

With this view of rights, a right bestows on its holders a sphere of absolute inviolability – an abstract space within which they can do what the right entitles them to do (protest, hold property, speak, associate or whatever), subject to nothing and no-one else, with no limitations. Rights are seen as instruments through which to separate ourselves from other people and unilaterally impose our will and our interests on others. Rights operate as trumps, boundaries, conversation stoppers.

Understanding human rights

Fortunately, our constitution embodies a different vision or understanding of human rights. In various ways, our constitution makes it clear that what exactly our human rights entitle us to do, or have, or experience, is never abstractly fixed, immutable, or absolute, but must always be determined anew within context. Whenever we seek to exercise one of our human rights, its precise contours and limits must be determined in light of the circumstances prevailing at the time we seek to exercise it; the history of our country; the impact that our exercise thereof will have on the rights and interests of other people; and how our conduct in terms of the right aligns with the public interest and broader constitutional goals.

In this view of rights, our understanding of the right of ownership (which is of course not one of the human rights proclaimed in our constitution but is only indirectly protected in Section 25 of the Constitution) has been moulded into something entirely different from the apartheid conception. Landowners no longer have absolute, exclusive control over their land that simply arises from the fact that they have the right to ownership. If landowners today want to remove people occupying their land without any legal right to do so – in addition to and after proving their ownership – they must persuade a court that eviction would be just and equitable in light of all relevant circumstances (prevailing circumstances; interests of others, including the occupiers of their land; the public interest; constitutional goals) before they will succeed.

WATCH: The Power of Human Rights 




Building democracy

Likewise, if we seek to exercise our right to protest – in order to know what we would be entitled to do in terms of that right – we must consider how our protest will affect the rights and interests of others and whether that impact can be justified, and how the manner and form of our protest squares with constitutional goals such as building democracy. Equally, of course, if others object to our protest because of its impact on their rights and interest, they will have to contextualise their attempt to exercise their right to education, or academic freedom, or freedom of movement in light of our interests, the prevailing circumstances, the public interest, and constitutional goals such as fostering democracy, freedom of association, and freedom of speech.

That is, instead of rights in our constitutional order being abstract spheres of inviolability that can be exercised against others to protect or enforce our interests without consideration of context, keeping us apart, they are mechanisms to enable us to live together, to find accommodation between our disparate, perhaps conflicting, but often overlapping interests and concerns.

What is it then that our human rights do for us or entitle us to? Whenever our human rights-related interests are at stake, or if we rub up our fellow human beings with whom we cohabit the wrong way when our interests seem to clash, they entitle us to be taken equal account of. They require others (most importantly those in authority, usually the state) to include us and have concern for our interest, equal to the concern for others, in the conversation about what should happen and what we may or may not do. In this sense, rights do not keep us apart or stop conversations. Instead, they are acutely democratic mechanisms, making it possible for us to live together. ‘Only that?’, you may respond – but this is no small thing.

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.
