Pioneering greenhouse gas research in South African rainfed agriculture

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.

UFS increases admission requirements

2010-07-26

Admissions criteria for entry to undergraduate programmes at the University of the Free State (UFS) will be increased with immediate effect. This means that students who begin their undergraduate studies in 2011 will need to meet the new admissions criteria in order to register.

“Increasing admissions requirements is a critical component of our unwavering commitment to excellent academic standards and educational quality at the UFS,” said Prof. Driekie Hay, Vice-Rector: Teaching and Learning at the UFS.

“The challenge of student success at most South African universities is something that has attracted increasing attention over the past few years. We believe that it is our responsibility as an educational institution to admit students that we are confident are likely to be successful, and also to provide the very best quality of teaching and learning to ensure success.”

The university is also acutely aware that large numbers of young people in the country attend schools that are not adequately resourced to provide the quality of schooling needed for successful university study.

“We are thus committed to working with schools and with talented learners in order to address this challenge,” said Prof. Hay.

“The university currently has several initiatives in this regard. Further, our innovative and extremely successful University Preparation Programme (UPP) provides an opportunity for students with potential who do not meet the university entrance criteria to complete a bridging year that prepares them for the rigours of university.”

For students who begin their studies in 2011 the following changes will come into effect:

The minimum requirement for entry into undergraduate programmes will increase from 28 points to 30 points.
The minimum requirement for entry into extended programmes will increase from 23 points to 25 points.
The minimum requirement for entry into the University Preparation Programme will increase from 17 points to 20 points.
Subject-specific requirements specified by faculties will remain the same, except for Natural and Agricultural Sciences (contact the Faculty Manager at 051 401 3199).
All programmes that already require a minimum score of 30 points and above will not be changed.
The minimum entrance criteria for the B.Ed. Foundation Phase and B.Ed. Intermediate Phase will increase from 23 points to 25 points.
The minimum entrance criteria for B.Soc.Sc. Nursing will increase from 28 to 29 points.

Performance in the National Benchmark Tests will be used for placing students into academic support modules as needed.

These test results will not be used for admissions decisions in 2011, except for Faculties where it is used as part of their selection process.
Prospective students are encouraged to submit their applications for study in 2011 as soon as possible.
For telephone enquiries, please dial 051 401 3000.
