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.

Nanotechnology breakthrough at UFS
2010-08-19

 Ph.D students, Chantel Swart and Ntsoaki Leeuw


Scientists at the University of the Free State (UFS) made an important breakthrough in the use of nanotechnology in medical and biological research. The UFS team’s research has been accepted for publication by the internationally accredited Canadian Journal of Microbiology.

The UFS study dissected yeast cells exposed to over-used cooking oil by peeling microscopically thin layers off the yeast cells through the use of nanotechnology.

The yeast cells were enlarged thousands of times to study what was going on inside the cells, whilst at the same time establishing the chemical elements the cells are composed of. This was done by making microscopically small surgical incisions into the cell walls.

This groundbreaking research opens up a host of new uses for nanotechnology, as it was the first study ever in which biological cells were surgically manipulated and at the same time elemental analysis performed through nanotechnology. According to Prof. Lodewyk Kock, head of the Division Lipid Biotechnology at the UFS, the study has far reaching implications for biological and medical research.

The research was the result of collaboration between the Department of Microbial, Biochemical and Food Biotechnology, the Department of Physics (under the leadership of Prof. Hendrik Swart) and the Centre for Microscopy (under the leadership of Prof.Pieter van Wyk).

Two Ph.D. students, Chantel Swart and Ntsoaki Leeuw, overseen by professors Kock and Van Wyk, managed to successfully prepare yeast that was exposed to over-used cooking oil (used for deep frying of food) for this first ever method of nanotechnological research.

According to Prof. Kock, a single yeast cell is approximately 5 micrometres long. “A micrometre is one millionth of a metre – in laymen’s terms, even less than the diameter of a single hair – and completely invisible to the human eye.”

Through the use of nanotechnology, the chemical composition of the surface of the yeast cells could be established by making a surgical incision into the surface. The cells could be peeled off in layers of approximately three (3) nanometres at a time to establish the effect of the oil on the yeast cell’s composition. A nanometre is one thousandth of a micrometre.

Each cell was enlarged by between 40 000 and 50 000 times. This was done by using the Department of Physics’ PHI700 Scanning Auger Nanoprobe linked to a Scanning Electron Microscope and Argon-etching. Under the guidance of Prof. Swart, Mss. Swart en Leeuw could dissect the surfaces of yeast cells exposed to over-used cooking oil. 

The study noted wart like outgrowths - some only a few nanometres in diameter – on the cell surfaces. Research concluded that these outgrowths were caused by the oil. The exposure to the oil also drastically hampered the growth of the yeast cells. (See figure 1)  

Researchers worldwide have warned about the over-usage of cooking oil for deep frying of food, as it can be linked to the cause of diseases like cancer. The over-usage of cooking oil in the preparation of food is therefore strictly regulated by laws worldwide.

The UFS-research doesn’t only show that over-used cooking oil is harmful to micro-organisms like yeast, but also suggests how nanotechnology can be used in biological and medical research on, amongst others, cancer cells.

 

Figure 1. Yeast cells exposed to over-used cooking oil. Wart like protuberances/ outgrowths (WP) is clearly visible on the surfaces of the elongated yeast cells. With the use of nanotechnology, it is possible to peel off the warts – some with a diameter of only a few nanometres – in layers only a few nanometres thick. At the same time, the 3D-structure of the warts as well as its chemical composition can be established.
