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.

‘Your capacity for change is limitless’

 “You will change this campus, city, country, continent and the world, because you have the capacity for greatness,” Prof Jonathan Jansen, Vice-Chancellor and Rector of the University of the Free State (UFS), said.

He addressed the 2013 group of first-year students in the Leadership for Change programme at a farewell function before they will leave for universities abroad. The first 104 students from the 2013 total of 144 will depart on 18 September and return on 3 October 2013. The second group of 40 students will be abroad from 11 to 25 January 2014. The students are from the Bloemfontein and Qwaqwa Campuses. They will be accompanied by mentors from the UFS.

The students will visit 17 universities in the USA, Europe and Asia.

The first 71 first-year students in the Leadership for Change programme were sent abroad for two weeks in September 2010 to get intense exposure to the academic, social, cultural and residential lives of students in the USA. In 2011 the student number more than doubled and universities in Europe were included. In July 2012 the programme brought students from around the globe to the UFS for the Global Leadership Summit.

Prof Jansen inspired the young leaders, saying, “If you learn leadership values in your four years of study, a change will come. Build the new value system and take it into the country. Your capacity for change is limitless.”

He encouraged them to learn to know the stranger, not only abroad, but also the beggar at the street corner. “Learn to be comfortable with the beggar, as well as with the professor in the classroom.”

A stringent evaluation and training programme preceded the group’s visit abroad, and Prof Jansen could not formulate their achievement better: “I cannot tell you how proud I am of you.”
