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.

SRC elections of our Bloemfontein Campus

2011-07-26

The Student Council elections of our university at the Bloemfontein Campus will take place on 29 and 30 August 2011. These official election dates were announced by Mr Rudi Buys, Dean: Student Affairs, on 25 July 2011.

Nominations open on Wednesday, 27 July 2011 and the elections, which are constituted according to the SRC Constitution, shall be handled by the Independent Electoral Agency, which shall be instituted by the SRC Constitution with this in view.

“The elections introduce a new era in student leadership and governance, because student representation will now constituted in such a way that affords the majority of students the opportunity to vote directly for their representatives. Senior leadership structures are extended in the new Constitution, in order to allow more students to hold senior positions,” states Mr Buys.

The SRC elections follow on the approval of a new Constitution that was accepted by our Council on 3 June 2011.

The Constitution was drafted over a period of eight months by the Broad Student Transformation Forum (BSTF), consisting of students, in order to design a new dispensation in student structures. The BSTF, which decided on new models of student representation in collaboration with independent facilitators, consists of more than 70 student organisations and residences. The changes to the Constitution were decided on and accepted by the BSTF, after recommendations from four student study groups, which investigated student leadership and governance in depth, at national as well as international level, were taken into account. The study groups visited nine (9) other SA universities, as well as investigated student representation at internationally renowned universities like Cornell, Yale and Stanford in the United States of America.

Ms Modieyi Motholo, Chairperson of the Interim Student Committee, says that she is very proud of what the students have achieved with the new Constitution. “I wish to accord recognition to all the students who lead the process for all their hard work. Constitutional revision is a strenuous process and it is nothing short of a miracle that the students could not only reconstruct the Constitution, but also have it accepted in less than a year.”

The important changes include, amongst others:

Candidates no longer stand on behalf of parties in the elections, but as independent candidates for 10 predetermined portfolios for which students can vote directly;
Students also directly vote for a President and a Vice-President;
Nine (9) SRC members serve ex-officio as SRC members by virtue of being chairpersons of nine additional student councils established by the Constitution. Amongst others, the councils include a postgraduate student council, an international student council, a student media council and a student academic affairs council;
More stringent eligibility requirements are set for candidates, namely that students who wish to run in the elections has to, amongst others, sustain an academic average of more than 60%, and hold proven student leadership experience (which could be verified by the Independent Electoral Agency).

“With the SRC elections, students have the opportunity to firmly entrench the changes in student governance on which they have decided on by themselves firmly, as a sustainable model for democracy at our Bloemfontein Campus. It speaks volumes that the number of leadership positions for which candidates can make themselves available, in essence has been increased by the number of additional student sub-councils from 21 to 67, because it brings about much more direct representation for different students across the campus,” says Mr Buys.

“I firmly believe that the upcoming student council elections will be a success,” says Motholo. “I wish the students, who are prepared to sacrifice a year of their lives in service of the student community as a member of the SRC, all of the best.”

The Qwaqwa Campus’ election schedule shall be announced within the next week, as well as the date of the institution of the Central Student Council (CSC).
