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.

Race, technology, and maritime labour in the 19th century

2016-06-23

Prof John T. Grider

“When employers
impose
worker identity,
it creates problems.”

What does identity mean to people today, and how is it formed? Religion, politics, race, ethnicity, and gender make up individual and community identity. However, Prof John Grider (University of Wisconsin – La Crosse) is of the opinion that employment moulds our identity, since we spend so much time on the job.

Prof Grider joined the Institute for Reconciliation and Social Justice (IRSJ) on the Bloemfontein and Qwaqwa Campuses to discuss his research on the maritime industry, published in his book, Foreign Voyage - Pacific Maritime Labour Identity: 1840 to 1890. “When employers impose worker identity, it creates problems,” he said. Particularly, this “creates instability in communities, and a vulnerability and insecurity amongst the employees”.

To illustrate his point, Prof Grider expanded on the history of 19th-century Atlantic sailors, a highly-skilled workforce, who failed to adapt to changes in their labour environment. Initially, the sea-faring community was very diverse racially. However, as the Pacific, and particularly Asian, marine community gained precedence, this tide turned to such an extent that, in 1886, the Atlantic sailors formed their own Coastal Seamen’s Union in San Francisco, causing a split between Asian and non-Asian sailors. Atlantic sailors had failed to integrate with the new technology of the day (steam power), nor had they accepted the demographic changes that flooded their community rapidly with cheap labour from Chinese shores.

Prof Grider highlighted the need to maintain an adaptable mentality in the ever- and rapidly-changing labour world, since division amongst workers could lead only to further exploitation of the workforce.
