Farming Northen Asia is a far cry from Southern Africa, not that the farmers wont learn, but its a completely different beast. The lowest temp ever recorded in cape town are just barely below freezing. Typically its dealing with highs in the 60s during the winter.
Not to mention the cultural differences. Some make take Russia up on it, but I wouldnt expect most to.
The land being offered up is in more temperate parts of Russia with little drought and is highly fertile. These people deal with 10 year droughts in extremely sandy soil (not particularly fertile). A little cold weather is nothing to them. Russian wine tastes like Koolaid with gasoline added (Extreme fusel alcohol content.) I am sure any wine makers will get farms on the Caspian and world class wine will become a major export. 15,000 signed up to go. It is SHTF time in SA. We got out in 78. MENE, MENE, TEKEL, UPHARSIN
