Apart from its devastating impact on people’s lives and livelihoods, the COVID-19 pandemic has also affected the nature and quality of our democracies – democracy read in its widest sense here as collective and individual self-determination. Formal, institutional democracy has beencurtailed through the imposition of states of emergency or disaster and the logistical difficulties associated with social distancing. Extra-institutional democratic work, such as protest and social-movement activity, has suffered from prohibitions imposed by law and through state suppression related to ‘lockdown’. The nature (and perhaps democratic quality) of public conversation has changed – for better or worse – from increasing reliance on ‘science’ and ‘scientists’ to justify public choices. The crisis has brought to the fore already existing characteristics of our democracies, such as the prevalence and power of special-interest bargaining, the extreme inequality of our societies, and chauvinist nationalisms that force us to ask whether we have ever had democracy at all. What will be the long-term effects of these impacts of the crisis on our democracies? What will democracy look like post-COVID? What does the crisis teach us about what our democracies have always been?

Join us for a discussion of these and other democracy-related issues in these troubled times by a panel of four hailing from Colombia, India, South Africa, and the USA.

Date: Thursday, 13 August
Time: 14:00-16:00 (South African Standard Time – GMT +2)

Plant eco-physiologist finds effective solutions for crop optimisation

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.
