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.

Stem cell research and human cloning: legal and ethical focal points
2004-07-29

   

(Summary of the inaugural lecture of Prof Hennie Oosthuizen, from the Department of Criminal and Medical Law at the Faculty of Law of the University of the Free State.)

 

In the light of stem cell research, research on embryo’s and human cloning it will be fatal for legal advisors and researchers in South Africa to ignore the benefits that new bio-medical development, through research, contain for this country.

Legal advisors across the world have various views on stem cell research and human cloning. In the USA there is no legislation that regulates stem cell research but a number of States adopted legislation that approves stem cell research. The British Parlement gave permission for research on embryonic stem cells, but determined that it must be monitored closely and the European Union is of the opinion that it will open a door for race purification and commercial exploitation of human beings.

In South Africa the Bill on National Health makes provision for therapeutical and non therapeutical research. It also makes provision for therapeutical embryonical stem cell research on fetuses, which is not older than 14 days, as well as for therapeutical cloning under certain circumstances subject to the approval of the Minister. The Bill prohibits reproductive cloning.

Research on human embrio’s is a very controversial issue, here and in the rest of the world.

Researchers believe that the use of stem cell therapy could help to side-step the rejection of newly transplanted organs and tissue and if a bank for stem cell could be built, the shortage of organs for transplants would become something of the past. Stem cells could also be used for healing of Alzheimer’s, Parkinson’s and spinal injuries.

Sources from which stem cells are obtained could also lead to further ethical issues. Stem cells are harvested from mature human cells and embryonic stem cells. Another source to be utilised is to take egg cells from the ovaries of aborted fetuses. This will be morally unacceptable for those against abortions. Linking a financial incentive to that could become more of a controversial issue because the woman’s decision to abort could be influenced. The ideal would be to rather use human fetus tissue from spontaneous abortions or extra-uterine pregnancies than induced abortions.

The potential to obtain stem cells from the blood of the umbilical cord, bone-marrow and fetus tissue and for these cells to arrange themselves is known for quite some time. Blood from the umbilical cord contains many stem cells, which is the origin of the body’s immune and blood system. It is beneficial to bank the blood of a newborn baby’s umbilical cord. Through stem cell transplants the baby or another family member’s life could be saved from future illnesses such as anemia, leukemia and metabolic storing disabilities as well as certain generic immuno disabilities.

The possibility to withdraw stem cells from human embrio’s and to grow them is more useable because it has more treatment possibilities.

With the birth of Dolly the sheep, communities strongly expressed their concern about the possibility that a new cloning technique such as the replacement of the core of a cell will be used in human reproduction. Embryonic splitting and core replacement are two well known techniques that are associated with the cloning process.

I differentiate between reproductive cloning – to create a cloned human embryo with the aim to bring about a pregnancy of a child that is identical to another individual – and therapeutically cloning – to create a cloned human embryo for research purposes and for healing human illnesses.

Worldwide people are debating whether to proceed with therapeutical cloning. There are people for and against it. The biggest ethical objection against therapeutical cloning is the termination of the development of a potential human being.

Children born from cloning will differ from each other. Factors such as the uterus environment and the environment in which the child is growing up will play a role. Cloning create unique children that will grow up to be unique individuals, just like me and you that will develop into a person, just like you and me. If we understand this scientific fact, most arguments against human cloning will disappear.

Infertility can be treated through in vitro conception. This process does not work for everyone. For some cloning is a revolutionary treatment method because it is the only method that does not require patients to produce sperm and egg cells. The same arguments that were used against in vitro conception in the past are now being used against cloning. It is years later and in vitro cloning is generally applied and accepted by society. I am of the opinion that the same will happen with regard to human cloning.

There is an argument that cloning must be prohibited because it is unsafe. Distorted ideas in this regard were proven wrong. Are these distorted ideas justified to question the safety of cloning and the cloning process you may ask. The answer, according to me, is a definite no. Human cloning does have many advantages. That includes assistance with infertility, prevention of Down Syndrome and recovery from leukemia.
