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.

Kovsies paint Bethlehem red!

“The learners of the High School Witteberg are a wonderful example of the quality of students that we can expect as first years here at Kovsies next year,” Prof. Jonathan Jansen, Rector and Vice-Chancellor of the University of the Free State (UFS) said last night during a matric evening attended by 121 Grade 12 learners and their parents in a packed hall at the Secondary School Witteberg in Bethlehem.

Prof. Jansen and his wife Grace, as well as some of his colleagues were guests of honour at the event.

“We want to make a difference in the lives of our students at Kovsies and we want to ensure that our students make a difference in a divided world. This is why I want each Grade 12 learner who is here tonight to come and study at the UFS,” he told the learners and their parents.

“The UFS is going to become the university in the country that is serious about quality. We want to draw the best students. Quality entails hard work. It is about perseverance and your commitment towards your studies. That is the type of students we want.”

“My door is open to our students and they have access to come and talk to me. I also regularly sit at different places on the campus and then invite students to come and talk to me. I want our students to feel at home here.”

“I also want our students to feel free to talk about the use of language at the UFS. We love Afrikaans, English and Sesotho and are not going to fight about language. We are going to develop the use of Afrikaans so that more students can speak it – and this also goes for English and Sesotho.”

Prof. Jansen said that Kovsie students had to be balanced students. “Our students must also excel in sport, art, etc., because the development of students who are properly prepared for the workplace is what we strive for as a tertiary institution. Therefore we are going to establish an office that assists students in their career preparation and will offer students internships so that they can come into contact with leading firms in the commerce and industry sectors.”

“However, we shall also actively enhance our students’ learning experience and therefore we are going to send a group of first-year students overseas in the second semester this year to gain knowledge about issues like integration and collaboration.”

At the occasion Prof. Jansen announced that bursaries to study at the UFS in 2011 would be awarded to the two top Grade 12 learners of the school.

The Secondary School Witteberg had a 100% pass rate in the Grade 12 final examinations the past few years. In 2009 the school was seventh amongst the top 50 schools in the Free State Province. Five learners from the school were also amongst the top 20 learners in the Province last year. The school has already produced many top students for the UFS.
