As young Political Science undergraduate student, phrases such as ‘national security’ made sense. It was the 1980s and the machinations of the Cold War rivals fascinated me. In the national context of apartheid South Africa, the national security management system of former President PW Botha drew my attention. The realpolitik of the time, both global and national, resulted in me avidly reading countless tomes of first-strike capabilities of the nuclear powers and regional destabilisation strategies of the apartheid pariah. 

National security considerations vs lived experiences of ordinary people
With the passing of time, I grew increasingly disillusioned with national security as a suitable fit for contemporary times on account of two reasons. First, national security considerations were far removed from the lived experiences of ordinary people. A US factory worker in Michigan is more concerned about the closure of his local automotive plant than the machinations of Beijing in the South China Sea. National security always reflected the concerns of the elites in their respective societies, as opposed to the bread-and-butter considerations of the vast majority of humanity. In the African context, such elite-driven state security was often purchased at the expense of the human security of ordinary citizens. Here, the guns of the military were often directed at marginalised and hapless citizens, as opposed to being directed at keeping borders safe from a possible foreign invading force. National security therefore needs to be expanded to incorporate the concerns of ordinary citizens. Second, in this rapidly globalising world, insecurity anywhere is a threat to security everywhere. The COVID-19 pandemic illustrates the point well, whether one resides in Wuhan, Milan, Moscow, New York, Sao Paolo or Cape Town. The world is one, and national security needs to be jettisoned in favour of more integrated conceptions of security.

Regional mobilisation
The current locust plague sweeping across East Africa vividly highlights the need for more expanded definitions of security. This locust plague has been labelled by the UN as an “extremely alarming and unprecedented threat”. Currently, Sudan and South Sudan, Ethiopia, Kenya, Somalia, and Uganda are all affected by swarms of locusts travelling at 90 miles per day and eating their own body weight in crops. To put matters into perspective, a swarm of locusts of only one-third of a square mile can eat the same amount of food as 35 000 adults. This undermines food security across the region. To exacerbate matters, the lockdowns as a result of the coronavirus has hampered efforts to eradicate the swarms. Regional governments are overwhelmed, as Helen Adoa, Uganda’s Minister of Agriculture, admitted. This admission highlights the fallacy of national security in a globalising world. Regional governments need effective regional organisations to support their efforts and should partner with international organisations, including the UN Food and Agricultural Organization, civil society, and business, to holistically respond to the threat. I write this paper on Africa Day, 25 May – a day celebrating African solidarity. 

This African solidarity stands in sharp contrast to the realpolitik and insular politics embraced by the concept of national security and its corollary national interest. Sovereignty in defined areas needs to be ceded to regional organisations and global institutions in an effort to craft truly regional and global solutions. No one country can deal with either COVID-19 or swarms of marauding locusts.

An integrated understanding of security 
The origins of the current locust infestation currently overwhelming East Africa also points to the imperative for integrated understandings of security. Climate change has created the ideal breeding ground for the locust population in the Arabian Peninsula to increase by 8 000 percent. A phenomenon known as the Indian Ocean Dipole created unusually dry weather in the east, which resulted in wildfires ravaging Australia. The same phenomenon, however, also created cyclones and flooding in parts of the Arabian Peninsula and Somalia. The resultant moist sand and vegetation proved the ideal conditions in which desert locusts could thrive. Aiding the burgeoning locust populations is the collapsed state authorities in both Yemen and Somalia, ravaged by civil war and fighting Al Shabaab insurgents. As the writ of the ‘governments’ in both Sanaa and Mogadishu hardly goes beyond the capital, neither country can even launch a national response to the locust plague. 

The origins of the swarms of locusts devastating east Africa link climate change, civil war, state authority and capacity, and the COVID-19 pandemic. This stresses the need for holistic solutions which are rooted in expanded and integrated conceptions of security. We cannot afford to work in silos at national, regional, or international level.

Extraordinary times call for more holistic conceptions of security. The Cold War is over, my undergraduate lectures on security are a poor fit to today’s realities. The world stands at a pivotal point, much as it stood following the Thirty Years’ War in Europe and the resultant 1648 Treaty of Westphalia, the 1815 Congress of Vienna following the Napoleonic Wars, and the aftermath of the Second World War. We need to be brave and refashion our security architecture to reflect integrated, global, and human security considerations.

Imagine that you have been diagnosed with bone cancer and only have six months to live. You are in a wheelchair because the pain in your legs is so immense that you can’t walk anymore – similar to a mechanism eating your bones from the inside.

You are lucky though, since you could be injected with a drug to control the pain so effective that you will be able to get out of the wheelchair within a day-and-a-half and be able to walk again. Real-life incidents like these provide intense job satisfaction to Prof André Roodt, Head of Inorganic Chemistry at the University of the Free State (UFS). The research, which is conducted by the Inorganic Group at the UFS, contributes greatly to the availability of pain therapy that does not involve drugs, but improves the quality of life for cancer patients.

The research conducted by the Inorganic Group under the leadership of Prof Roodt, plays a major role in the clever design of model medicines to better detect and treat cancer.

The Department of Chemistry is one of approximately 10 institutions worldwide that conducts research on chemical mechanisms to identify and control cancer. “The fact that we are able to cooperate with the Departments of Nuclear Medicine and Medical Physics at the UFS, the Animal Research Centre, and other collaborators in South Africa and abroad, but especially the methodology we utilise to conduct research (studying the chemical manner in which drugs are absorbed in cancer as well as the time involved), enhances the possibility of making a contribution to cancer research,” says Prof Roodt.

Technique to detect cancer spots on bone
According to the professor, there are various ways of detecting cancer in the body. Cancer can, inter alia, be identified by analysing blood, X-rays (external) or through an internal technique where the patient is injected with a radioactive isotope.

Prof Roodt explains: “The doctor suspects that the patient has bone cancer and injects the person with a drug consisting of an isotope (only emits X-rays and does no damage to tissue) that is connected to a phosphonate (similar to those used for osteoporosis). Once the drug is injected, the isotope (Technetium-99m) moves to the spot on the bone where the cancer is located. The gamma rays in the isotope illuminate the area and the doctor can see exactly where treatment should be applied. The Technetium-99m has the same intensity gamma rays as normal X-rays and therefore operates the same as an internal X-ray supply.” With this technique, the doctor can see where the cancer spots are within a few hours.

The same technique can be used to identify inactive parts of the brain in Alzheimer patients, as well as areas of the heart where there is no blood supply or where the heart muscle is dead.

Therapeutic irradiation of cancer
For the treatment of pain connected with cancer, the isotope Rhenium-186 is injected. Similar to the manner in which the Technetium-99m phosphonate compound is ingested into the body, the Rhenium-186 phosphonate travels to the cancer spots. Patients thus receive therapeutic irradiation – a technique known as palliative therapy, which is excellent for treating pain. A dosage of this therapy usually lasts for about two months.

The therapy is, however, patient specific. The dosages should correspond with the occurrence and size of cancer spots in the patient’s body. First, the location of the cancer will be determined by means of a technetium scan. After that, the size of the area where the cancer occurs has to be determined. The dosage for addressing total pain distribution will be calculated according to these results.

Technique to detect cancer spots on soft tissue
Another technique to detect cancer as spots on bone or in soft tissue and organs throughout the body is by utilising a different type of irradiation, a so-called PET isotope. The Fluor-18 isotope is currently used widely, and in Pretoria a machine called a cyclotron was produced by Dr Gerdus Kemp, who is a former PhD graduate from the Inorganic Research Group. The F-18 is then hidden within a glucose molecule and a patient will be injected with the drug after being tranquillised and after the metabolism has been lowered considerably. The glucose, which is the ‘food' that cancer needs to grow, will then travel directly to the cancer area and the specific area where the cancer is located will thus be traced and ‘illuminated’ by the Fluor-18, which emits its own 'X-rays'.

In the late 80s, Prof Roodt did his own postdoctoral study on this research in the US. He started collaborating with the Department of Nuclear Medicine at the UFS in the early 90s, when he initiated testing for this research.

Through their research of more than 15 years, the Inorganic Group in the Department of Chemistry has made a major contribution to cancer research. Research on mechanisms for the detection of cancer, by designing new clever chemical agents, and the chemical ways in which these agents are taken up in the body, especially contributes to the development in terms of cancer therapy and imaging, and has been used by a number of hospitals in South Africa.

The future holds great promise
Prof Roodt and his team are already working on a bilateral study between the UFS and Kenya. It involves the linking of radio isotopes, as mentioned above, to known natural products (such as rooibos tea), which possess anti-cancer qualities.
