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.

CONTROL OF INFECTIOUS AVIAN DISEASES – LESSONS FOR MAN?

“Many of the lessons learnt in disease control in poultry will have application on human medicine,” said Prof Robert Bragg, lecturer at the University of the Free State’s (UFS) Department of Microbial, Biochemical and Food Biotechnology during his inaugural lecture.

Prof Bragg said the development of vaccines remains the main stay of disease control in humans as well as in avian species.  Disease control can not rely on vaccination alone and other disease-control options must be examined.  

“With the increasing problems of antibiotic resistance, the use of disinfection and bio security are becoming more important,” he said.

“Avian influenza (AI) is an example of a disease which can spread from birds to humans.  Hopefully this virus will not develop human to human transmission,” said Prof Bragg.

According to Prof Bragg, South Africa is not on the migration route of water birds, which are the main transmitters of AI.  “This makes South Africa one of the countries less likely to get the disease,” he said.

If the AI virus does develop human to human transmission, it could make the 1918 flu pandemic pale into insignificance.  During the 1918 flu pandemic, the virus had a mortality rate of only 3%, yet more than 50 million people died.

Although the AI virus has not developed human-to-human transmission, all human cases have been related to direct contact with infected birds. The mortality rate in humans who have contracted this virus is 67%.

“Apart from the obvious fears for the human population, this virus is a very serious poultry pathogen and can cause 100% mortality in poultry populations.  Poultry meat and egg production is the staple protein source in most countries around the world. The virus is currently devastating the poultry industry world-wide,” said Prof Bragg.

Prof Bragg’s research activities on avian diseases started off with the investigation of diseases in poultry.  “The average life cycle of a broiler chicken is 42 days.  After this short time, they are slaughtered.  As a result of the short generation time in poultry, one can observe changes in microbial populations as a result of the use of vaccines, antibiotics and disinfectants,” said Prof Bragg.   

“Much of my research effort has been directed towards the control of infectious coryza in layers, which is caused by the bacterium Avibacterium paragallinarum.  This disease is a type of sinusitis in the layer chickens and can cause a drop in egg product of up to 40%,” said Prof Bragg.

The vaccines used around the world in an attempt to control this disease are all inactivated vaccines. One of the most important points is the selection of the correct strains of the bacterium to use in the vaccine.

Prof Bragg established that in South Africa, there are four different serovars of the bacterium and one of these, the serovar C-3 strain, was believed to be unique to Southern Africa. He also recently discovered this serovar for the first time in Israel, thus indicating that this serovar might have a wider distribution than originally believed.

Vaccines used in this country did not contain this serovar.  Prof Bragg established that the long term use of vaccines not containing the local South African strain resulted in a shift in the population distribution of the pathogen.

Prof Bragg’s research activities also include disease control in parrots and pigeons.   “One of the main research projects in my group is on the disease in parrots caused by the circovirus Beak and Feather Disease virus. This virus causes serious problems in the parrot breeding industry in this country. This virus is also threatening the highly endangered and endemic Cape Parrot,” said Prof Bragg.

Prof Bragg’s research group is currently working on the development of a DNA vaccine which will assist in the control of the disease, not only in the parrot breeding industry, but also to help the highly endangered Cape Parrot in its battle for survival.

“Not all of our research efforts are directed towards infectious coryza or the Beak and Feather Disease virus.  One of my Masters students is currently investigating the cell receptors involved in the binding of Newcastle Disease virus to cancerous cells and normal cells of humans. This work will also eventually lead to a possible treatment of cancer in humans and will assist with the development of a recombinant vaccine for Newcastle disease virus,” said Prof Bragg.

We are also currently investigating an “unknown” virus which causes disease problems in poultry in the Western Cape,” said Prof Bragg.
 
“Although disinfection has been extensively used in the poultry industry, it has only been done at the pre-placement stage. In other words, disinfectants are used before the birds are placed into the house. Once the birds are placed, all use of disinfectants stops,” said Prof Bragg.

“Disinfection and bio security can be seen as the ‘Cinderella’ of disease control in poultry.  This is also true for human medicine. One just has to look at the high numbers of people who die from hospital-acquired infections to realise that disinfection is not a concept which is really clear in human health care,” said Prof Bragg.

Much research has been done in the control of diseases through vaccination and through the use of antibiotics. “These pillars of disease control are, however, starting to crumble and more effort is needed on disinfection and bio security,” said Prof Bragg.

Prof Bragg has been working in close co-operation with a chemical manufacturing company in Stellenbosch to develop a unique disinfectant which his highly effective yet not toxic to the birds.

As a result of this unique product, he has developed the continual disinfection program for use in poultry. In this program the disinfectant is used throughout the production cycle of the birds. It is also used to ensure that there is excellent pre-placement disinfection.

“The program is extensively used for the control of infectious diseases in the parrot-breeding industry in South Africa and the product has been registered in 15 countries around the world with registration in the USA in the final process,” said Prof Bragg.

“Although the problem of plasmid mediated resistance to disinfectants is starting to rear its ugly head, this has allowed for the opening of a new research field which my group will hopefully exploit in the near future,” he said.
