On 11 September 2022 a tailings dam wall collapsed at the abandoned Jagersfontein diamond mine in the Free State’s Kopanong Local Municipality, unleashing a thick grey sludge. 

The mine is in the Xhariep District Municipality, which is home to about 5 800 people. Following the dam burst, more than 400 people were affected, 51 houses were destroyed, and critical infrastructure was affected. 

The dam burst at the mine, which was established in the 1800s and to date has been owned by several mine moguls, led to serious devastation in the community. Within hours of the event the media had already dubbed it the “Jagersfontein disaster”. 

But the media cannot loosely report it as a “disaster”. It is not the appropriate classification according to the Disaster Management Act. There is a need for governing institutions and their legislation to be respected and recognised, as this will improve on governance. South Africa has good policies, but implementation is, in certain areas, lacking. Hereunder, we note that there is inappropriate use of terminology, which depicts the inadequate understanding of the disaster risk management function.

What is a disaster?

The DMA defines a “disaster” as a progressive, sudden, widespread, natural, or man-made occurrence that causes or threatens to cause death, disease or injury, damage to the environment, and disruption of life. According to the Act, it is of a magnitude that “exceeds the ability of those affected by the disaster to cope with its effects using only their resources”. At the international level, the United Nations International Strategy for Disaster Reduction (UNISDR) developed a terminology guide that aims to promote a common understanding and usage of disaster management concepts. It assists the authorities and the public (in this case, by “public” we refer mainly to the media) in educating the populace.

For the dam burst to be termed a “disaster”, several steps must be adhered to within South African jurisprudence: 

The National Disaster Management Centre (NDMC) must first assess the magnitude and severity of the event, and then classify it as a local, provincial, or national disaster. This assessment also considers the provisions of Section 2 (1)(b) of the DMA, stating that the Act does not apply to an occurrence that can be dealt with in terms of other legislation. The rationale of the above is that the National Disaster Management Framework of 2005 (NDMF) provides that disaster management plans must be developed by relevant organs of states and other entities, who are the custodians of certain hazards or activities to manage disaster risks in their areas of legislative responsibility. For example, mining-related activities are the responsibility of the Department of Mineral Resources and Energy. This department’s mission is clear: to regulate, transform and promote the mineral and energy sectors. 

Since the event or incident occurred in a local sphere of government (Kopanong Local Municipality), it can then be classified as a local disaster subject to the satisfaction of the provisions of Section 2(1)(b). According to Section 23(4) of the DMA, an event can be classified as a “local disaster” if it affects a single local metropole, district, or municipality, and that entity can deal with the event effectively. The district municipality and the local municipality are responsible for the coordination and management of the local disaster. 

If the event has not been declared as a local state of disaster, other existing legislation, contingency arrangements, or by-laws can guide the management of the event in line with the appropriate contingency arrangements. Other government spheres and state organs can still assist with the management of the event in line with the applicable disaster risk management plans called for under the National Disaster Management Frameworks. 


Dr Mmaphaka Tau 

Of critical importance and aligned to the thrust of the District Development Model is the provision of Section 54 (4) of the DMA, which asserts that “irrespective of whether a local state of disaster has been declared in terms of section 55, a national or provincial organ of state, or another municipality or municipal organs of state are not precluded from providing assistance to a municipality to deal with a local disaster and its consequences”. 

In the same way, and on the strength of section 23 of the DMA, suppose the event has been classified as a local disaster: there are added benefits to dealing with the occurrence, especially in the face of a lack of robust disaster risk management plans and the dearth of disaster risk management implementation capacity both for coordination (by Disaster Management Centres) and mainstreaming (by relevant organs of state and other entities). In that case, the municipal council may declare a local state of disaster by notice in the provincial gazette (See Section 55 of the DMA).

The disaster declaration will then provide for measures such as, but not limited to:
• Available resources such as facilities, vehicles, and funding are released; 
• Personnel of the organs of the state are released to render emergency services; 
• Evacuation of the affected population to temporary shelters;
• The regulation of movement;
• The dissemination of information; 
• The maintenance and/or installation of temporary lines of communication; and 
• The suspension of or limiting of alcohol in disaster-stricken areas.
Therefore, until all the above processes have been followed, the Jagersfontein dam burst can only be termed a “disaster” without the ability to apply the above measures.

Who is responsible, and how can we move forward?

Jagersfontein Developments (Pty) Ltd owns the mine, implying that it should be their primary responsibility, as the asset owner, to actively contribute to the management of the occurrence of an incident. Even the Minister of Mineral Resources and Energy, Gwede Mantashe, rightfully stated that the responsibility of compensating affected individuals would be placed on the mine owners. According to the Mine Health and Safety Act 29 of 1996 and its regulations, “the employer must take reasonable measures to ensure that no person is injured as a result of the failure of any dam wall”. It was reported that the company was warned of the tailings exceeding the authorised waste volumes. But the company did not attend to the warning. It is also assumed that the company is aware of the policies, legislation and standards they should adhere to, such as the Global Industry Standard on Tailings Management (GISTM), which strives to achieve the goals of zero harm to people and the environment, mine safety, and to mitigate catastrophic failure through tailings management. Fortunately, the company has taken full responsibility and has accepted liability. They have also refrained from calling Jagersfontein a ‘mine’, opting to call it a “processing facility”. Perhaps this also has legal implications. 

Nonetheless, besides the company taking full responsibility, the government must also play its part and make sure that policies, legislation, standards, etc. are implemented, and that there is full compliance. 
They cannot wait for a catastrophic event to occur and then start pointing fingers. This scenario calls for an embracing of the principles and practices of risk-informed development, which calls for an understanding of development that considers multi-faceted, dynamic, interdependent, transboundary, simultaneous, and systemic risks. It thus describes a shift in mindset – across sectors and stakeholders – from managing single hazards to incorporating existing and future risks in all development processes from the outset, and therefore choosing development pathways that prevent the creation of risks. The Jagersfontein case study is a classic case of an ignored Risk Informed Development (RID) approach, which is gravely regrettable.

The limited understanding of the various stakeholders’ roles and responsibilities, and the misinterpretation of important terminology, call for robust capacity development programmes driven by the National Disaster Management Centre in collaboration with Provincial and Municipal Disaster Management Centres. There is also a palpable need for a firm implementation of Priority 1 (Understanding Disaster Risk) of the Sendai Framework for Disaster Risk Reduction 2015-2030 (SFDRR), which states that policies and practices for disaster management should be based on an understanding of risks in all dimensions of vulnerability, capacity, exposure of persons and assets, hazard characteristics, and the environment.

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.
