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.

New SRC constitution for UFS main campus agreed upon by all organisations

2005-07-20

University of the Free State Fact Sheet

1. The Council of the University of the Free State (UFS) unanimously approved an amendment to the SRC constitution for the main campus to allow for the introduction of proportional representation (PR) alongside a first-past-the-post electoral system.

2. This decision was taken by the UFS Council on 10 June 2005 at the same meeting where it also approved the establishment of a Central SRC for the three campuses of the UFS.

3. The new main campus SRC constitution is the result of consensus reached during a lengthy negotiation process involving diverse student formations such as Sasco, the ANC Youth League, the Young Communist League, the ACDP, HEREXVII, KovsieAlliance, as well as the democratically elected SRC members of the main campus. Independent persons such as Mr Jack Klaas and Mr Kobus van Loggerenberg facilitated the negotiation process.

4. The consensus reached during this process, and the subsequent decision by Council, represent a major breakthrough for student governance and transformation of the UFS main campus and constitutes a legitimate basis for the democratic participation of all students at the UFS main campus in the governance of the university.

5. The introduction of the proportional representation system follows earlier calls by some student formations, notably Sasco and the ANC Youth League, for such a system to be introduced at the UFS main campus in Bloemfontein.

6. In terms of the amendments to the main campus SRC constitution, nine of the 18 SRC members are to elected by means of proportional representation and nine on the basis of an direct, first-past-the-post election.

7. The following portfolios of the main campus SRC will be contested by individual candidates on the basis of “first past the post”:
• president
• secretary
• academic affairs
• legal and constitutional affairs
• student development
• arts and culture
• men’s internal liaison
• ladies internal liaison
• media, marketing and liaison

8. The following nine portfolios will be contested by affiliated organizations on a proportional representation basis.
• two vice-presidents
• treasurer
• dialogue and associations
• transformation
• campus affairs and recreation
• sport
• international affairs
• community service

9. These two decisions regarding student governance represent a breakthrough in that, for the first time in many years, all SRC constitutional changes were processed and approved by the June meeting of the Council, well in time for the scheduled August SRC election; in addition, all relevant student organizations have been part of the process and all have accepted the outcome of the process.
