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.

Emotional health of vulnerable children needs urgent intervention
2014-02-04



In South Africa, thousands of children under the age of 18 are orphaned as a result of HIV/Aids. Experts are worried that these orphans and vulnerable children will experience serious socio-emotional problems and behaviour disorders, should urgent intervention programmes not be implemented urgently.

A study was undertaken by the Centre for Development Support at the UFS, in conjunction with Stellenbosch University and the Houston University in America. The research found that in the Free State province alone, about 15% of orphans and vulnerable children showed signs of psychiatric disorders. Almost half of the children in the study showed signs of abnormal or maladjusted behavioural functioning.

The research team believes that the South African government and the numerous non-governmental organisations put too much emphasis on the physical needs of orphaned and vulnerable children and that their socio-emotional or mental wellbeing receives very little attention.

The nominal financial grant is a welcome relief for some of the needs of this risk group. Researchers are worried, though, that the lack of reliable and culturally-sensitive diagnostic methods for the early detection of psychiatric disorders may pose a challenge when the children reach puberty.

The current study is focusing on the detection of emotional behavioural problems even before adolescence. Questionnaires were distributed across the Free State at clinics, schools and non-governmental organisations dealing with these children. The questionnaires enabled researchers to establish the children's socio-emotional needs.

"Overcrowding in houses where orphans and vulnerable children often live is directly linked to poor socio-emotional health in children," says Prof Lochner Marais from the Centre for Development Support. "The state institutions offering programmes for orphans and vulnerable children overemphasise the physical and/or financial needs of these children. The programme provides, for example, food for the children, grants for the [foster] parents, assistance with school clothes and ensures clinic visits for the children. Of these, only the supply of food has a direct impact on the improved mental health of children."

The study provides, for the first time, a profile of the state of mind of this group, as well as the emotional impact of HIV/Aids – an "urgent matter" according to Dr Carla Sharp from the University of Houston's Department of Psychology. According to Dr Sharp, much more could be done to assist foster parents in addressing the emotional needs of these children. The early detection of behavioural disorders should be the key in intervention programmes.
