Cervical cancer awareness ribbon
Cervical Cancer Awareness Month is observed in September in South Africa to encourage women to go for screening to prevent it.

Cervical cancer is the second most common cancer among women in South Africa, and many die from it each year – but it can be prevented.

According to Dr Arina Meyer, medical practitioner in Kovsie Health at the University of the Free State, this is one of the reasons why it is important to be informed, take precautions, and raise awareness about the disease.

Cervical Cancer Awareness Month is observed in September in South Africa with the aim of encouraging women to go for screening to prevent it.

Although medical statistics paint a bleak picture, Meyer says there is hope. “It is important to know that cervical cancer can be prevented. And when it is diagnosed early, it can be treated.”

Statistics and causes

According to her, figures show the occurrence of cervical cancer to be between 22,8 and 27 per 100 000 women in South Africa. 

“More than 5 700 new cases are reported each year, as well as more than 3 000 deaths. Cervical cancer is the second most common cancer – after skin cancer – in South Africa.”

Meyer says when one look at these numbers, it is important to commemorate Cervical Cancer Awareness Month, as women need to be informed about their annual check-up, possible symptoms, and signs of the cancer.

Most cervical cancers are caused by the human papillomavirus (HPV), which is transmitted through sexual contact. Therefore, the HPV is seen as a sexually transmitted disease.

“There are different types of HPV. Some cause cervical cancer and other genital warts. One can develop one or both conditions, depending on the type of virus you have,” says Meyer.

Prevention and reducing the risk

According to her, preventative action is the best method. Going for a cervical screening every year when you become sexually active, such as a Pap smear or Pap test, will help in the early detection and removal of abnormal cells.

There is also a vaccine for protection against HPV, which is available from the age of nine. Meyer says there are two vaccines in South Africa.

“By getting the vaccine early, before any sexual activity, the spread of HPV – and therefore cervical cancer – can be prevented. Up to 90% of cancers can be prevented.
“Unfortunately, if someone has already been infected by the HPV, it cannot be treated by the vaccine.”

The UFS medical practitioner says the best ways to reduce the risk of cervical cancer are to go for an annual Pap smear, a follow-up after an abnormal test result, the vaccine, safe sex, and to stop smoking.

“This rating will motivate me to do more research, to improve outcomes, and to aim for a higher C-rating.” This was the response of Dr Jay le Roux, who was recently graded as an Y2-rated researcher by the National Research Foundation (NRF).

Dr Le Roux, senior lecturer in the Department of Geography at the University of the Free State (UFS), is one of 31 new NRF-rated researchers at the UFS. “This grading will make it possible to focus on more specific research during field research and to come in contact with other experts. Researchers are graded on their potential or contribution in their respective fields,” he said.

Research assess different techniques
His research on water erosion risk in South Africa (SA) is a methodological framework with three hierarchal levels presented. It was done in collaboration with the University of Pretoria (UP), Water Research Commission, Department of Agriculture, Forestry and Fisheries, and recently Rhodes University and the Department of Environmental Affairs. Dr Le Roux was registered for 5 years at UP, while working full-time for the Agricultural Research Council – Institute for Soil, Climate and Water (ARC-ISCW).

Water erosion risk assessment in South Africa: towards a methodological framework
, illustrates the most feasible erosion assessment techniques and input datasets that can be used to map water erosion features in SA. It also emphasises the simplicity required for application at a regional scale, with proper incorporation of the most important erosion-causal factors.

The main feature that distinguishes this approach from previous studies is the fact that this study interprets erosion features as individual sediment sources. Modelling the sediment yield contribution from gully erosion (also known as dongas) with emphasis on connectivity and sediment transport, can be considered as an important step towards the assessment of sediment produce at regional scale. 
 
Dams a pivotal element in river networks

Soil is an important, but limited natural resource in SA. Soil erosion not only involves loss of fertile topsoil and reduction of soil productivity, but is also coupled with serious off-site impacts related to increased mobilisation of sediment and delivery to rivers.

The siltation of dams is a big problem in SA, especially dams that are located in eroded catchment areas. Dr Le Roux recently developed a model to assess sediment yield contribution from gully erosion at a large catchment scale. “The Mzimvubu River Catchment is the only large river network in SA on record without a dam.” The flow and sediment yield in the catchment made it possible to estimate dam life expectancies on between 43 and 55 years for future dams in the area.
 
Future model to assess soil erosion
“I plan to finalise a soil erosion model that will determine the sediment yield of gully erosion on a bigger scale.” It will be useful to determine the lifespan of dams where gully erosion is a big problem. Two of his PhD students are currently working on project proposals to assess soil erosion with the help of remote sensing techniques.
