To add more information to the article. I have been slowly trying to build up a hydroponics shaded structure. I have to finance this myself so this will take a few years. There a few reasons I am doing this. I want an alternative to an office job. Sometimes just sitting in front of a computer drains the soul. I don't trust the financial systems in my home country and have my doubts if my pension will support me later in life. I do think there is a profit to be made. A fare amount of food is imported.
The weird thing is that small scale farming will only be viable as long as Africa is not attractive to big farmers. The moment big farmers can get going I think it will be the end of small scale farming.
