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.

The Great Pool of Exhilaration

Boys’ roars and ladies’ shouts could be heard from miles away. From this, one could tell that the 2015 first-year’s Swimming Gala was bound to be an exciting one.

While RC Sports members were stressing, the first-years blissfully continued in song and excitement.

One would think that, after a hectic first week of classes, first-years would not have much energy left, but the atmosphere proved that Residence Committees (RCs) had prepared the individuals with rather motivating pep talks before the event. Most male residences put their best foot forward, not holding back on themed attire and additional instruments, while female residences sang and danced to the music provided. Not only were the masses competing to claim that they had the greatest spirit on this night, but they were also waiting to hear the results of the Spirit Cup for the first-years’ Athletics, which was cut short due to heavy rain showers. This simply added to the already intense anticipation of first-years and RC Sports members, as they would receive the results only at the end of the event.

The competition was tough as many of the first-years who competed moved with ease in the water as though it was second nature to them. This year’s gala saw quite a few talented, national swimmers competing, which left those who swam for pride and points intimidated. The excitement of the crowd was heightened as the relay section of the programme approached. This meant that the winners were to be announced soon.

In the ladies’ section, the residences were placed:
• 1st – Marjolein
• 2nd – Wag-‘n-Bietjie
• 3rd – Sonnedou

In the men’s section, the residences were placed:
• 1st – Armentum
• 2nd – Vishuis
• 3rd – Karee

When the time arrived for the announcement of the Spirit Cup winners, many were hopefully clenching their hearts for their name to be roared out. In most people’s opinion, it came as no surprise when Armentum walked away with the Spirit Cup for both the first-years’ Athletics and the Swimming Gala. Furthermore, Armentum’s broader South College community – of which Emily Hobhouse, Marjolein, NJ vd Merwe and Villa Bravado are also part – walked away with the cash prize for the best mascot.

By end of the night, everyone, no matter if they were drenched or dry, experienced the exciting sporting atmosphere at Kovsies that they’ve now become a part of.
