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 eco-physiologist finds effective solutions for crop optimisation

that the product has been tested
on a crop.

In a time characterised by society facing increasing population growth, food crises, and extreme climatic conditions such as drought, it is essential for farmers to integrate science with their work practices in order to optimise crops.

Role of photosynthesis and plant sap data

By knowing how to use photosynthesis and plant sap data for determining plant health, fast and effective solutions could be established for the optimisation of crops. This technique, which could help farmers utilise every bit of usable land effectively, is the focus of Marguerite Westcott’s PhD study. She is a junior lecturer and plant eco-physiologist in die Department of Plant Sciences at the University of the Free State.

Westcott uses this technique in her studies to prove that a newly-developed bio-stimulant stimulates plants in order to metabolise water and other nutrients better, yielding increased crops as a result.

Agricultural and mining sectors benefit from research

The greatest part of these projects focuses on the agricultural sector. Westcott and a colleague, Dr Gert Marais, are researching the physiology of pecan and citrus trees in order to optimise the growth of these crops, thus minimising disease through biological methods. Field trials are being conducted in actively-producing orchards in the Hartswater and Patensie areas in conjunction with the South African Pecan Nut Producers Association (SAPPA) amongst others.
 
The principles that Westcott applies in her research are also used in combination with the bio-stimulant in other studies on disturbed soil, such as mine-dump material, for establishing plants in areas where they would not grow normally. This is an economical way for both the agricultural and mining sectors to improve nutrient absorption, stimulate growth, and contribute to the sustainable utilisation of the soil.

The bio-stimulant contributes to the immunity of the plants.
It was tested in these pecan nut orchards (Hartswater).

Soil rehabilitation key aspect in research projects

“One of two things is happening in my research projects. Either the soil is rehabilitated to bring about the optimal growth of a plant, or the plants are used to rehabilitate the soil,” says Westcott.

Data surveys for her PhD studies began in 2015. “This will be a long-term project in which seasonal data will be collected continuously. The first set of complete field data, together with pot trial data, will be completed after the current crop harvest,” says Westcott.
