Nearly 150 students from across the world will gather in Egypt for the COP27 Simulation Model from 9 September to mid- October 2022. Among them will be Letsatsi Lekhooa, a Master of Science student specialising in Climate Change from the University of the Free State (UFS).

Lekhooa was one of 150 students from a pool of more than 1 800 applicants across the world who were selected to be part of this prestigious initiative. “This opportunity is appealing, because as young people we need to work hard to not only ensure that we break through walls, but to also represent our university well everywhere we go,” Lekhooa indicated.

The COP27 Simulation Model

The COP27 Simulation Model, which is organised by the British University in Egypt along with the United Nations Development Programme (UNDP), is a worldwide climate conference led by and targeted at the youth. The conference is important for several reasons, such as encouraging conversations around climate action among the youth. As it stands, the initiative is split into two categories, which include the hybrid capacity-building programme that started in September, and the COP27 Mock Conference set to begin in October. Lekhooa is currently engaged in the online capacity-building programme, which he describes as a learning curve. “Every day I learn something new, and I enjoy it because the process is assisting me in learning more about this climate change issue,” Lekhooa expressed.

The benefits of attending the COP27 Mock Conference

Although the first leg of the COP27 Simulation Model is online, Lekhooa will get the opportunity to travel to Egypt and physically be part of the COP27 Mock Conference on the campus of the British University in Egypt. As such, he hopes to take away as much as possible from the experience. “I hope to learn about the ways in which I can better communicate this climate change issue, not only in my home country of Lesotho, but generally in Southern Africa,” said Lekhooa. Furthermore, through his interactions with international scholars, he hopes to create and encourage a collaborative spirit to battle climate change.

The experience does not only serve as a learning curve for Lekhooa, but it is also one of the key steps that will allow him to reach a life goal. “I would like to be an international consultant in bodies such as the Intergovernmental Panel on Climate Change (IPCC), and the United Nations Framework Convention on Climate Change (UNFCCC), as they play a key role in making decisions on climate change,” Lekhooa highlighted.

Plant eco-physiologist finds effective solutions for crop optimisation

2016-07-24

The bio-stimulant was tested on
this citrus. This is the first time
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.
