Agri Western Cape says it's worrying that attacks on farms are spiralling out of control.
At least four attacks were reported on Western Cape farms in the past month.
In the latest incident earlier this week, a 47-year-old man was shot and killed on a Klapmuts farm near Stellenbosch.
Police say Joubert Conradie was investigating a noise in his house when he was attacked and shot by gunmen.
Agri Western Cape CEO Carl Opperman said: “We are devastated by the loss of life on the farms. [Whether] It is the farmers or the farm workers, it is a loss on a farm that is producing food for the South African consumers. The increase that we’re picking up at the moment, is very worrying and we are very concerned.”
Agri Western Cape and AfriForum have both indicated they will heed a call to wear black on Monday in memory of those who have been killed in attacks on farms.
A farmer and friend of one of the farmers murdered recently has posted an emotional video on social media, urging the farming community to wear black T-shirts and stand in solidarity.
