DvB: We have a poverty crisis in the deep rural areas of the former homelands. The lack of livelihoods for people in these areas leads to millions flocking to the cities which are struggling to cope with the influx.

We need to create decent incomes for people in these areas but the the lack of roads and other agricultural infrastructure makes it almost impossible for small farmers to compete with the efficiencies of the giant Agri-businesses that dominate SA's food production. The cost here of getting a small loads of cabbages to market on 100km of bad dirt roads results in farmers selling at a loss. Hence we need a high value crop that is easy to grow and is not already being grown by the giant Agri-businesses.

Obviously, if there is a crop that yields millions of rand per hectare then big Agri-business will wish to take control ASAP. Hence the need to restrict the growing to small farmers in the former homelands where we have the biggest need for economic development.
