The COVID-19 pandemic has exposed the fracture lines in societies worldwide. South Africa is no different. The poor are less able to protect themselves from the danger posed by the virus. Workers in factories, mines, and the service sector went back to their places of work following the lifting of the strictest lockdown measures, while office workers, typically better paid, can generally work from home. Living conditions in informal settlements make social distancing all but impossible, while the middle class can largely stay at home and stay safe to a much larger extent. With many businesses shutting down, downsizing or rethinking their business models, it is often small and medium, as well as informal sector businesses that are most affected.  

The impact of COVID-19 comes on the back of a society and economy that was already under significant pressure following years of low economic growth and poor government performance. Many commentators have already questioned the social compact South Africans made in the mid-1990s, which marked the end of the apartheid regime. These divisions have become more glaring, with some civil society organisations considering challenging the Minister of Finance’s adjustment budget in the Constitutional Court, because the budget might result in a roll-back of the progressive realisation of the socio-economic rights mandated in the Constitution.

In this first of four webinars, academics from the UFS as well as invited experts reflect on the constitutional commitment South Africans made to one another two and half decades ago. Is it time for a new deal? Should we collectively recommit ourselves to our existing deal? Do we interpret that deal in the same way today as we did more than two decades ago? How does the economic reality we face, particularly in the aftermath of the COVID-19 crisis, affect that deal? What are the economic realities we face, and whose are they? And how should we think about human development in the context of our deal? 

Come and join us from 14:00 to 15:30 on 21 July. 

RSVP to Sibongile Mlotya at MlotyaS@ufs.ac.za no later than 19 July, upon which you will receive a Business for Skype meeting invite.

Speakers:
Prof Danie Brand on ‘New deal’ or collective recommitment? The Constitution under COVID-19 and beyond

Prof Melanie Walker on Human development and the capability approach in COVID-19 times

Prof Lochner Marais on Reflections on continuities and discontinuities after COVID-19

Prof Philippe Burger on Viewing the realisation of socio-economic rights in a post-COVID-19 South Africa through an economic lens

Sunflowers are satellite dishes for sunshine, or are they?
2016-07-20

Eighty-six percent of South Africa’s
sunflowers are produced in the
Free State and North West provinces.

Helen Mirren, the English actress, said “the sunflower is like a satellite dish for sunshine”. However, researchers at the University of the Free State (UFS) have found that too much of this sunshine could have a negative effect on the growth of sunflowers, which are a major source of oil in South Africa.

According to Dr Gert Ceronio from the Department of Soil, Crop, and Climate Sciences at the UFS, extremely high soil temperatures play a definite role in the sprouting of sunflower seedlings. Together with Lize Henning, professional officer in the department, and Dr André Nel from the Agricultural Research Council, he is doing research on biotic and abiotic factors that could have an impact on sunflowers.

Impact of high temperatures on sunflower production

The Free State and North West provinces, which produce 86% of South Africa’s sunflowers, are afflicted especially by high summer temperatures that lead to extremely high soil temperatures.

Dr Ceronio says: “Although sunflower seeds are able to germinate at temperatures from as low as 4°C to as high as 41°C, soil temperatures of 35°C and higher could have a negative effect on the vegetative faculty of sunflower seedlings, and could have an adverse effect on the percentage of sunflowers that germinate. From the end of November until mid-January, this is a common phenomenon in the sandy soil of the Free State and North West provinces. Soil temperatures can easily exceed the critical temperature of 43°C, which can lead to poor germination and even the replanting of sunflowers.”

Since temperature have a huge impact not only on the germination of sunflower seeds, but also on the vegetative faculty and sprouting of sunflower seedlings, Dr Ceronio suggests that sunflowers should be planted in soil with soil temperatures of 22 to 30°C. Planting is usually done in October and early November. Unfortunately, this is not always possible, as soil moisture is not optimal for growth. Farmers are then compelled to plant sunflowers later.

Impact of herbicides on sunflower growth

“High soil temperatures, combined with the herbicide sensitivity of some cultivars, could lead to the poor development of seedlings," says Dr Ceronio.

The use of herbicides, such as ALACHLOR, for the control of weeds in sunflowers is common practice in sunflower production. It has already been determined that ALACHLOR could still have a damaging effect on the seedlings of some cultivars during germination and sprouting, even at recommended application dosages.

“The purpose of the continued research is to establish the sensitivity of sunflower cultivars to ALACHLOR when exposed to high soil temperatures,” says Dr Ceronio.
