Agriculture in South Africa contributes around 5% of formal employment, relatively low compared to other parts of Africa and the number is still decreasing, as well as providing work for casual laborers and contributing around 2.6 percent of GDP for the nation. Due to the aridity of the land, only 13.5 percent can be used for crop production, and only 3 percent is considered high potential land. The government has been accused of either putting in too much effort, or not enough effort, to tackle the problem of farm attacks as opposed to other forms of violent crime.
