Tsamayang Sethunsa says women needs to be taught that they must be firm when they say no.

“Gender-based violence is everyone’s responsibility and I believe it can be reduced if we all work together, says Tsamayang Sethunsa, Crime Investigating Officer at Protection Services.

Although he considers this a difficult battle to win, there are some actions that we can take to start fighting this evil in society. 

Enhance awareness campaigns

“We must continue to enhance our awareness campaigns throughout the year and not restrict it to the short period of time during the 16 Days of Activism against violence to women and children campaign. Awareness campaigns need to run on a regular basis and must become part of our daily lives.”

He adds that we need to be proactive. “In this regard, I am a firm supporter of ongoing research to enable advocacy groups, investigators, victims, and perpetrators to understand what we are dealing with and to come up with mitigation plans that will address the problem at its roots,” he says. 

“I also believe a focus on the victim is a good beginning, but we do not need to forget about the perpetrator, as that is where the problem is. We need to conduct specific research where perpetrators are interviewed and assessed as to understand what made the person commit the crime. You do not wake up in the morning and decide to hurt or kill someone you are supposed to love. There must be a trigger and we need to address it through ongoing engagement with men as the common perpetrator in these crimes.”

It is all right to cry and to let the pain out

“It is also important that men are taught to speak out about challenges they face on a daily basis. Tell them it is all right to cry and to let the pain out instead of keeping things in, resulting in violent outbursts,” he adds.

Tsamayang is also of the opinion that there is a need to revisit the rehabilitation methods of correctional service centres and to determine if these methods are working.

He says the issue of repeat offenders is also a growing concern for him as an investigator.

Furthermore, he is convinced that young children need to be taught about gender-based violence from an early age. “Women also need to be taught that they must be firm when they say no, and to report any criminal activity immediately when it happens. They must also learn to protect themselves,” he says.

UFS venture cleans up acid mine drainage

South Africa is one of the most important mining countries in the world, beginning in the 1870s. Although the mining industry has been responsible for significant development and employment, it pollutes the environment and waters sources. Through the joint effort of a well-known mining company, the University of the Free State, and the Technology Innovation Agency (UFS/TIA) SAENSE Group, a new treatment for Acid Mine Drainage (AMD) has been developed.

The system treats the major contaminants found in acid mining wastewater effectively.  
 
The UFS remediation systems use a reservoir tank into which the AMD is pumped. The water then flows passively (without using energy) to the Barium Carbonate Dispersed Alkaline Substrate (BDAS) system. The metals and anions in the AMD react chemically with the barium carbonate and precipitate (form solids). The solids stay in the tank while the clean water is released.

The efficacy and applicability of the research was demonstrated on site in Belfast, Mpumalanga where the team constructed a pilot plant in July 2014. This patented technology has treated 1 814 400 litres of Acid Mine Drainage to date with an outflow water quality that satisfies the South African National Standards (SANS) 241:2006 & 2011 regulations for drinking water.   

Rohan Posthumus from the (UFS/TIA) SAENSE Group said: “At this stage, we do not recommend that the water should be used as drinking water, but certainly it can lower water usage in mines while finding application in dust suppression of washing processes. The team would like to complete a full characterisation of the final released water. There are currently no toxic by-products formed, and even very basic filtration can make the outflow drinking water.”

Prof Esta van Heerden’s research group from the Department of Microbial, Biochemical, and Food Biotechnology has been working on AMD research for some time, but the development of the BDAS system was started in 2013 by post-doctoral student, Dr Julio Castillo, and his junior researcher, Rohan Posthumus.

The data from the BDAS system have led to two publications in peer-reviewed journals as well as a registered patent.
