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 offers bursaries for interpreters

2005-12-01

The Unit for Language Management (previously Unit for Language Facilitation and Empowerment) at the University of the Free State (UFS) is offering bursaries to persons who want to apply for the Post-graduate Diploma in Language Practice (interpreting) for 2006.

The Unit was involved in the setting up of a comprehensive interpreting infrastructure at the Free State Legislature and provided the interpreting services for the Truth and Reconciliation Commission (TRC) for the latter’s full duration.

“The UFS supports a multilingual society. Our language policy, which was approved by the Council in 2003, is a striking example. This policy is in accordance with the national movement towards multilingualism and the recognition of language rights. Through the training of interpreters the UFS is empowering others to exercise their language rights and to partake meaningfully in formal conversations,“ said Prof Theo du Plessis, head of the UFS Unit for Language Management (ULM).

“The UFS has been using interpreter services at executive management meetings and other occasions such as meetings, seminars and conferences for several years. The demand for these services has risen quite considerably. We have found that the current three interpreters on the Main Campus will soon not be able to cope with this demand,” said Prof du Plessis.

According to Prof du Plessis institutions like the Mangaung Local Municipality and the Motheo District Municipality use the interpreter services of the ULM on a regular basis.
“Because the demand for interpreter services is becoming so great, the demand for trained interpreters is also increasing. This is why we are offering bursaries for persons who want to be trained as interpreters to register in 2006 for the Post-graduate Diploma in Language Practice (interpreting) as offered by the UFS Department of Afro-asiatic Studies and Language Practice and Sign Language,” said Prof du Plessis.

According to Prof du Plessis the UFS will be able to use these students on an ad-hoc basis to assist with interpreter services on the Main Campus or to deliver interpreter services to institutions outside the UFS.

The bursaries will preferably be awarded to persons with English as mother tongue with an above average knowledge of Afrikaans or Sesotho. The duration of the bursaries is one year and only tuition fees will be paid. “To qualify for the bursaries, prospective students must have an undergraduate qualification,” said Prof du Plessis.

The closing date for applications is 25 January 2006. For any enquiries, Mrs Susan Lombaard can be contacted at (051) 401-2405 or 072 605 4966 during office hours or at lombasc.hum@mail.uovs.ac.za.
