Dr Jerry Dlamini, lecturer and researcher specialising in agronomy within the Department of Soil, Crop, and Climate Sciences at the University of the Free State (UFS), is at the forefront of pioneering research in this field.

Greenhouse gas emissions represent a significant global concern, driving climate change on a massive scale. This concern is particularly pronounced in rainfed agriculture, where understanding and addressing these emissions are crucial for ensuring sustainable agricultural practices. 

In South Africa, rainfed agriculture is vital in food production, contributing substantially to the nation's agricultural output. However, this sector also stands as a notable contributor to greenhouse gas emissions, primarily through activities such as livestock farming, fertiliser use, and changes in land use.

Dr Jerry Dlamini, a distinguished lecturer and researcher specialising in agronomy within the Department of Soil, Crop, and Climate Sciences at the University of the Free State (UFS), is leading pioneering research in this field. His current project, @CROPGas on X, funded by the European Joint Programme (EPJ), with a budget of R22 million, focuses on investigating the impact of various conservation agriculture interventions on greenhouse gas emissions, primarily targeting nitrous oxide (N2O), methane (CH4), and carbon dioxide (CO2).

This two-year project, which commenced in December 2022 and concludes in December 2024, is a collaborative effort between European and African universities and institutions, including Rothamsted Research (UK), University College Dublin (Ireland), University of Nottingham (UK), University of Poznan (Poland), British Geological Surveys (BGS), University of Zambia (Zambia), University of Zimbabwe, and Lilongwe University of Agriculture and Natural Resources (Malawi). 

Dr Dlamini’s preliminary findings from the UFS Kenilworth Experimental Farm indicate that climate-smart agriculture interventions, such as legume rotation and no-till practices, have the potential to reduce the intensity of greenhouse gas emissions, particularly highly radiative gases like N2O.

“This is a significant finding,” Dr Dlamini noted, “as N2O has a global warming potential 100 times greater than CO2 over a 100-year horizon, meaning its impact on ozone depletion persists far longer despite being emitted in smaller quantities.”

Looking ahead, Dr Dlamini advocates for increased research efforts to quantify greenhouse gas emissions from South African croplands. He emphasises the importance of field-based measurements, akin to methodologies employed by other nations, to enhance the accuracy and effectiveness of South Africa's greenhouse gas inventories submitted annually to the United Nations Framework Convention on Climate Change (UNFCCC) and to devise effective mitigation strategies.

‘Is the South African university curriculum ‘colonial'?’ asks Prof Jansen

One of the critical issues that emerged from the South African student protests during 2015 and 2016 was a demand for the decolonisation of university curriculums. 

A senior professor at the Stellenbosch University, Prof Jonathan Jansen, said the number of people, including academics, who joined the cause without adequately interrogating the language of this protest, was astonishing. “The role of social scientists is to investigate new ideas … when something is presented to the world as truth.” Prof Jansen was speaking during a celebration lecture at the University of the Free State in Bloemfontein on 15 November 2017. 

Large amount of knowledge not African

He said the accusation is correct to a limited degree. “The objection, in essence, is against the centring of Western, and especially European knowledge, in institutional curricula.” There is no doubt that most of what constitutes curriculum knowledge in South African universities, and in universities around the world, derive from the West. “The major theories and theorists, the methodologists and methods are disproportionally situated outside of the developing world,” Prof Jansen said. 

The dilemma is, how will South Africa and the continent change the locus of knowledge production, considering the deteriorating state of public universities? “In the absence of vibrant, original, and creative knowledge production systems in Africa and South Africa, where will this African-centred or African-led curriculum theory come from,” Jansen asked. He says the re-centring of a curriculum needs scholars with significant post-doctoral experiences that are rooted in the study of education and endowed with the critical independence of thought. “South Africa's universities are not places where scholars can think. South African universities’ current primary occupation is security and police dogs,” Prof Jansen said. 

Collaboration between African and Western scholars
“Despite the challenges, not everything was stuck in the past,” Prof Jansen said. South African scholars now lead major research programmes in the country intellectually. The common thread between these projects is that the content is African in the subjects of study, and the work reflects collaboration with academics in the rest of the world. These research projects attract postgraduate students from the West, and the research increasingly affects curriculum transformations across university departments. There is also an ongoing shift in the locus of authority for knowledge production within leading universities in South Africa. Prof Jansen feels a significant problem that is being ignored in the curriculum debate, is the concern about the knowledge of the future. How does South Africa prepare its young for the opportunities provided by the groundswell of technological innovation? “In other parts of the world, school children are learning coding, artificial intelligence, and automation on a large scale. They are introduced to neuroscience and applied mathematics,” he said.

Prof Jansen said, in contrast, in South Africa the debate focuses on the merits of mathematics literacy, and what to do with dead people’s statues.
