Farming in Mozambique

As a fairly young family (two kids, one on the way) and both of us coming from a farming background we find ourselves dying to get out of the hustle and bustle of city life and, for lack of a better expression, going back to our roots.  But this dream seems very unattainable in the current South African climate.  We've heard that there are farming concessions available in Mozambique.  I'd like to get some more information but have as to yet not found anything.  I need to find out more about these concessions, which areas we need to look at, if it's worth my while relocating my small children, the availability of medical facilities, water, electricity, and so forth.  Can anyone please help?
