A well researched article. Yes, expropriation without compensation actually makes no sense whatsoever. The people claiming the land, do not do it because they want to farm. I believe that it might be that it is a kind of revenge they are seeking after Apartheid.
I was thinking, instead of giving a huge piece of land away, farmers should petition for keeping their own piece, while sharing smaller pieces of land with those who want to farm so badly. If they do what they are supposed to do, in other words, farming and supplying food to the market, then great! If they don't do that, the land should be expropriated again and given to another family. In this way, our beautiful farms of the past will not lie fallow, and our market could be enriched.
However, I do not think the people with the claims have any leg to stand on. Most of them are just as new to our country than we are. We did not steal land from their ancestors. We conquered a wild land that belonged to no-one!
