Dr Antonie Geyer was recently named Agriculturist of the Year by Agricultural Writers SA. It is the second time that he received this award.

Dr Geyer, Director: Agricultural Development in the Faculty of Natural and Agricultural Sciences at the University of the Free State (UFS), says: “I honestly feel honoured and humbled. I was awarded as the Agriculturist of the Year for the Eastern Cape in 2006, and in 2019 as the Agriculturist of the Year for the Free State. I always do my work to the best of my ability and to the advantage of the agricultural industry. I never expected these awards. I see it as proof of the successful impact on the industry.”

According to Agricultural Writers SA, the evaluation of this award is mainly about the essence, principles, value systems, and life ethics of the candidate as well as their achievements, the value of their work to the agricultural sector, and the candidate’s local and international status.

Candidates were also judged on how they shared their knowledge with farmers in a practical way, how valuable this knowledge was, and how it helped farmers to farm in a better and more sustainable way. Among others, Dr Geyer was for many years – even before he joined the UFS – involved in economic study groups for livestock farmers. He developed programmes and provided intelligent reports to individual farmers of the study groups. 

Advising on food security

This agricultural economist who is specialising in livestock economics and is currently regarded as one of the most experienced livestock economists in South Africa, is also passionate about projects and plans aimed at improving food security and sustainable farming. 

“Food security will always be an urgent necessity. The challenges are to secure food safety, food quality, and food security during these extremely difficult times. The economy needs to be stimulated to ensure an increase in the demand for the products supplied by the farmer. A growing economy will create the pull effect, resulting in the increase of demand. This is set for the local as well as the international markets,” he states.

“The most important fact is that we do not know when the drought is going to end. How accurate can one plan and budget? It is almost impossible. Every farm is different, and even more so during drought or disaster situations.”

“There are several factors that need to be managed simultaneously. Information on the disaster is very important: where to get help and what support is available; the veld condition, the condition of your animals; how to adapt to these extreme conditions; is the current production system still relevant under these circumstances; as well as communication with all the role players in your business, e.g. organised agriculture, the co-operatives, the applicable commodity groups, and the financial institutions,” Dr Geyer adds.

Message to future farmers

He believes South Africa urgently needs a new generation of farmers. Dr Geyer’s message to the next generation of farmers is: “There is a brilliant future for agriculture in South Africa. Be informed. Join organised agriculture in your area. Secure the best mentor possible. Gain experience from your fellow farmers in the community, but remember that each farm and community is different, with their own unique challenges. Make use of the latest technology. Keep on expanding and applying your knowledge.”

“The agricultural resources in South Africa is under tremendous pressure,” he states. In general, his dream for agricultural development in the country is to have a prosperous agricultural industry in South Africa, operating economically successful and in harmony with the natural resources.

Einstein's gravitational waves as creative as Bach's music, says UFS physicist

Profile of the gravitational waves of the colliding black holes.

Prof Pieter Meintjes, Affiliated Researcher in the Department of Physics at the University of the Free State, welcomed the work done by the Laser Interferometer Gravitational-Wave Observatory (LIGO) science team.
 
For the first time, researchers from two of the American Ligo centres, in Washington and Louisiana respectively, observed gravitational waves directly, 100 years after Albert Einstein said they existed. "My study field in astrophysics involves relativistic systems. Therefore, Einstein's view of gravity is crucial to me. I consider the theory as the highest form of human creativity - just like the music of JS Bach. Over the past 100 years, the theory has been tested through various experiments and in different ways.
 
“The discovery of gravitational waves was the last hurdle to overcome in making this absolutely unfaltering. I am therefore thrilled by the discovery. It is absolutely astounding to imagine that the equations used to make the predictions about the gravitational-wave emissions when two gravitational whirlpools collide - as discovered on 14 September 2015 by LIGO - are basically Einstein's original equations that were published way back in 1916 - in other words, 100 years ago.
 
“The LIGO detectors have been operational since the early 1990s, but they had to undergo several stages of upgrades before being sensitive enough to make detections. LIGO is currently in its final stage, and is expected to function at optimal sensitivity only within a year or two. To be able to conduct the measurements at this stage is therefore a fantastic achievement, since much more funding will certainly be deposited in the project,” Prof Meintjes says.

The search for gravitational waves by means of the Square Kilometre Array (SKA) is one of the focus points in research by both Prof Meintjes and PhD student, Jacques Maritz. This involves the study of radio signals from pulsars that might show signs of effects by gravitational waves. They are looking for signs of gravitational waves. The gravitational waves discovered and studied in this manner would naturally vary much more slowly than the signal discovered from the two colliding gravitational waves.
 
The discovery will definitely provide renewed impetus to the Square Kilometre Array (SKA) Project to use the dispersion of pulsar signals, and to search for the impact of gravitational waves on signals as they travel through the universe. According to Prof Meintjes, the SKA will definitely contribute fundamentally to the Frontier research, which will provide a good deal of publicity for the UFS and South Africa, if significant contributions are made by local researchers in this field.
