Land is becoming lesser and not very available for agriculture as before, There is a lot of Urbanization going on and many land space are being built on to carter for the increasing number of persons. There will be lesser organic foods available for consumption as the worlds population increase and farming space reduces. Because of this, there now has to be an improvement in farming methods and I personally consider vertical Farming to be the future of organic food farming.
There are two places to live in anywhere in the world. Either you live in Rural area or you live in Urban area. Now when someone was living in the rural area and moved down to Urban settlement then the place he or she was living at the rural area became vacancy, so occupying one place gives room to open another place. So that of the rural settlement space can be use has farming.
I don't know of other countries, in my locality, there are enough lands to farm but nobody to farm. Specifically, my paternal home town is a ghost town now because urbanization has taken over 99% of the people. So lands full there to farm.
While that's the case with some countries, there are countries where the population is too high and landscapes aren't that much, so even if there is a lot of land and spaces available right now, there will surely be more urbanization in the future and there will be a need of more lands as well. It might not happen, but as per the statistics of how the popularity of the world is increasing, it seems there will surely be a need for that in the coming days.
So, those countries which lack lands and spaces for farming might need to think of alternative ways of planting and producing organic food items like vegetables, grains, etc. Vertical farming might be a good solution if it's practiced on a large scale and can have a good success rate.
