According to the international market and consumer data company Statista’s June 2022 data, more than 4,6 billion people worldwide are using social media; this is an increase of 1 billion people compared to the total users in 2020. 

Delivering his lecture on ‘Social Media, Freedom of Expression, and the Law’ on the University of the Free State Bloemfontein Campus on 30 May 2022, John Jeffery, Deputy Minister of Justice and Constitutional Development, said, “The power of social media lies in the sheer magnitude of the number of people using it.”

He said: “Section 16 of the South African Constitution provides that everyone has the right to freedom of expression, which includes freedom of the press and other media; freedom to receive or impart information or ideas; freedom of artistic creativity; and academic freedom and freedom of scientific research.”

He advised perpetrators of malicious social media posts about the consequences and the harm to persons who are victims.

Depending on the circumstances, a person who suffers harm because of being the subject of someone else’s social media posts, can be protected under the Protection from Harassment Act. According to the Act, this is due to mental, psychological, physical, or economic harm.

Speaking at the Odeion School of Music, Deputy Minister Jeffery said, “Social media brings with it the importance of responsible use. As a social media user, you are entirely responsible for whatever appears on your social media accounts.’

He said: “Whatever you do in life – your conduct and your words – can be put onto various platforms and they will be there for a very long time. Do better, be better – and use social media to inspire people, to have an impact on the world, and to make it a better place.”

Plant-strengthening agent enhances natural ability of plants to survive
2015-07-27

Drought, diseases, and fungi. These are factors that farmers have no control over, and they often have to watch despondently as their crops are damaged. In addition, the practice of breeding plants in special and strictly-controlled conditions, has resulted in crops losing the chemical ability to protect themselves in nature.

Researchers in the Department of Soil, Crop, and Climate Sciences at the University of the Free State (UFS) have developed an organic agent that restores this chemical imbalance in plants. It enables the plant to build its own resistance against mild stress factors, and thus ensures increased growth and yield by the plant.

ComCat®, a plant-strengthening agent, is the result of extensive research by the German company, Agraforum AG, together with the UFS. Commercialisation was initially limited to Europe, while research was done at the UFS.

“Plants have become weak because they were grown specially and in isolation. They can’t protect themselves any longer,” says Dr Elmarie van der Watt from the department.

Dr Van der Watt says that, in nature, plants communicate by means of natural chemicals as part of their resistance mechanisms towards various stress conditions. These chemicals enable them to protect themselves against stress conditions, such as diseases and fungi (biotic conditions) or wind and droughts (abiotic conditions).

Most wild plant varieties are usually well-adapted to resist these stress factors. However, monoculture crops have lost this ability to a large extent.

The European researchers extracted these self-protection chemicals from wild plants, and made them available to the UFS for research and development.

“This important survival mechanism became dormant in monoculture crops. ComCat® wakes the plant up and says ‘Hey, you should start protecting yourself’.”

Research over the last few years has shown that the agent, applied mostly as a foliar spray, subsequently leads to better seedlings, as well as to growth, and yields enhancement of various crops. This is good news for the agricultural sector as it does not induce unwanted early vegetative growth that could jeopardise the final yield ? as happened in the past for nitrogen application at an early growth stage.

“The use of synthetic agents, such as fungicides which contain copper, are now banned. Nowadays, options for natural and organic agriculture is being investigated. This product is already widely used in Europe, but because farmers are often swamped by quacks, the South African market is still somewhat sceptical.”
