Have black farmers robustly succeeded in restoring a functional agricultural sector?””””
ABSOLUTELY NOT !!!
Before 2000, Zimbabwe grew enough food that they exported to other African countries and still had plenty for their own people.
Now, Zimbabwe must IMPORT over 97% of their daily needs.
It will take a complete overthrow ob Mugabe to clean this up & restore the farms.
IIRC, Rhodesia had 3 growing seasons and was the Bread Basket of Africa, that was BZ era.
