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.

Prof Habib addresses inequality at public lecture
2014-08-06

 
One of South Africa’s leading political commentators, Prof Adam Habib, gave a public lecture and launched his latest book on the Bloemfontein Campus on Wednesday 30 July 2014. The event was hosted by the Department of Philosophy in association with Wits University Press and The Southern African Trust.

Prof Habib started his lecture by summarising his book, ‘South Africa’s Suspended Revolution: Hopes and Prospects’. “It is basically about: how did we get where we are today, and how do we get out of the mess we are in?” he said.

His book focuses on South Africa’s transition into democracy and the country’s prospects for inclusive development – which formed the basis of his talk. Prof Habib stressed the issue of inequality facing South Africa and discussed the different approaches to addressing the matter.

“The one approach is that it is simply something we have to live with,” he said. “People who believe this live in a bubble. For example, service delivery protests do not happen because of poverty – it happens because of inequality.”

Prof Habib cautioned against not taking the matter seriously. “Inequality went up consistently in South Africa over the last 20 years. This is however not solely a national challenge, but a global challenge. And South Africa is the frontline of the war on inequality.”

He proposed that the expectations of the rich, rather than the poor, should be addressed.
“We need to moderate expectations. But we can’t moderate the expectations of the poor, if not the rich. We can’t ask the poor to sacrifice what the rich won’t.

“South Africa is once again at a moment of reckoning, where we are forced to make hard choices – in order to make the right choices.”
