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.

UFS SIFE is the best in SA!

2004-07-09

The SIFE team celebrates their victory with Jack Shewmaker, founder of SIFE in 1975 and past-president of Walmart in the USA, and Moses Kgosana, Chairman of KPMG SA.

The Students in Free Enterprise (SIFE) team of the University of the Free State competed in the National SIFE championships on Thursday, June 17, 2004 at Ceasar’s Convention Centre in Johannesburg.

Strong competition was experienced from the other ten participant SA universities, e.g. the Universities of the Western Cape, Kwazulu-Natal, Cape Town and RAU, but die UFS SIFE team retained the national championship for the third year running.

The team will now represent South Africa and the University of the Free State in Barcelona, Spain at die SIFE World Cup. The competition will be held from 22 to 24 September 2004.

The presentation team members for the competition were Tsholofelo Tlhomelang, Imameleng Matete, Kenneth Lefa, Kabelo Lephaka, Nadia van Staden, Tshepo Mahloko (Multi-Media), Werner Schmidt (Faculty Advisor). Supporting the presentation team were Lineo Peete, Keketso Ntene, Ruth Morienyane, Motaung Mathaba, Tshireletso Seekoe, Peter Letsoalo, Obakeng Msuthwana, Tshepiso Lebentle, JC Langeveldt and Michelle Stanley.

SIFE is a world-wide non-profit organisation with the express aim of encouraging students to spread their business knowledge - gained in the classroom - to the community, to promote and expand the principles of free enterprise.( www.sife.org )

The criteria by which SIFE-projects are measured are the following:

• How free markets work in the global economy.
• How entrepreneurs succeed by identifying a market need and then profitably producing and marketing a product or service to fill that need.
• The personal entrepreneurial, communications, technology and financial management skills needed to successfully compete.
• Practicing business in an ethical and socially responsible manner that supports the principles of a market economy.
• Measuring the results of projects, utilizing mass media and the Internet, involving non-business majors and utilizing a Business Advisory Board, communicating the program through a written report and verbal presentation.

The UFS’ SIFE-team’s presentation complied with all the above mentioned criteria. SIFE UFS’ education drive stretched from primary school learners, to adults who had been working for thirty years – this diverse group was taught about the free market system and its value in the global village. Business ethics and basic business principles were communicated in a fun and interactive way to learners. High-level business advice was given to entrepreneurs who started new projects, e.g. a brick-maker, and marketing advice were given to existing businesses in need of expansion.
