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.

Student leaders' hard work rewarded
2013-05-01

Four student leaders on our Bloemfontein and Qwaqwa Campuses each received a scholarship of R15 000. Handré Hay, Estine Cronje, Tsepang Lenka and Jean Vermaas were rewarded for the positive impact they had on the student community in the past three years or more. Student Affairs' scholarship programme acknowledges the contribution of student leaders in the upliftment of the student community.

Read what the four have to say about leadership:

Handré Hay:

Handré Hay, a third-year BSc Physiotherapy student who holds several leadership positions on our Bloemfontein Campus, served for two consecutive years on the committee of Armentum residence. He was also a member of the executive council in the Students' Representative Council (SRC) and served in two SRC portfolios. "Leadership is about being able to serve. When people see that you are willing to put other people's interests above your own and that you are willing to serve unselfishly, despite a position of authority, you will get far," said Handré.

Estine Cronje:

Estine Cronje is the current prime of Marjolein residence. This was the second time the fifth-year Psychology student were re-elected to this position."Leadership is very important to me. One needs leaders in everything you do. I believe a leader should never think herself better than the rest and should work as hard as her team. She should command respect, be disciplined, an example to others, accessible and open to the opinions of other people.

Tsepang Lenka:

Tsepang Lenka is the SRC President of our Qwaqwa Campus. Tsepang, who was twice elected as prime of his residence, has already obtained his BA degree in Public and Business Management. He is currently working on his Postgraduate Certificate in Education (PGCE). "To me leadership means to serve. As a leader you don't lie to people when things are taking the wrong direction, you stand firm and tell the truth; in that way, people don't lose trust in you. The scholarship inspires me to work even harder," Tsepang said.

Jean Vermaas:

Jean Vermaas is a former SRC member who is currently studying for his LLB degree. Some of Jean's achievements include leadership positions of the Juridical Society and the Broad Students' Transformation Forum. In 2012 he was a founder member of the Student Elders' Council."Leadership is of extreme importance to me. It formed me into the person I am now. Leadership isn't always easy, but in the challenges you face you grow as a leader and as an individual."
