Vertical Farming: What are the Advantages and Disadvantages of a Vertical Farm?

Vertical Farming: What is it and what are the benefits of establishing the vertical farm? See advantages and disadvantages of farmscrapers. This is the method of agriculture that has been proposed by Professor Dickson Despommier from Columbia University. He feels that there is a great need for inner city blocks to have their own immediate source of food where plants will be grown without soil, by means of aeroponics and hydroponics within buildings already known as "farmscrapers".

What is Vertical Farming?

With the over-population of the world ever increasing, and water and land being a finite source, alternative options are being sought for feeding the masses, yet minimizing land use. How are we going to continue to feed and house everyone? If we need more land for housing, then farmlands and forests will shrink. And yet, one needs that farmland to feed the masses, and the forests to produce oxygen and to sustain other life forms that are all part of the ecology.

So it seemed like a catch-22 situation until someone came up with the brilliant idea, or so it seems on the surface, of having city blocks of concrete and glass where you will be able to farm fish, poultry, pigs, fruit and vegetables all in a controlled environment in farmscrapers forming a vertical growing platform. So what are the benefits of all of this?

What are The Advantages of Vertical Farming?

Well, those who support this idea, believe that it is a far better way of producing crops and that there are more benefits than conventional farming. They claim that it is more efficient. How so? Well, all produce will be grown organically, with no pesticides and insecticides, as being in a controlled environment there are no insects or garden pests that can attack the plants.

Another benefit of some consideration is that the crops will be further protected from inclement weather, and therefore less crops will be lost to hurricanes, hail, drought and snap freezes, because the temperatures within these vertical growing platforms will be set at ambient temperatures. With global weather patterns becoming more unpredictable, and with global warming being a huge problem, vertical farming sounds like a solid option.

A further benefit of having a vertical farm is seen in the fact that having farms like these within the inner cities, the carbon footprint in miles of food transportation will be reduced, because the crops and produce are already there, within easy access to those who need them. Because they are able to recycle and use black water in their irrigation systems this is a further benefit to conserving drinking water, which is becoming more and more a resource of scarcity.

Considering how important water is for life in general, vertical farming seems to be the answer for a serious problem that many starving nations now face due to drought and lack of drinking water. In addition, with the plants being grown in these huge vertical greenhouses, the transpiration that will occur naturally will be harnessed and reused again for irrigation. Considering that conventional farming uses 70% of the world's drinkable water, and much of that is polluted by fertilizers and pesticides, this seems to be one of the greatest benefits.

What are the Disadvantages of Vertical Farming?

However, those are the benefits, what are some of the negative aspects that haven't been mentioned in vertical farming? Well, pollination is something that needs serious consideration. Insects are crucial to this process. So if this is going to be an insect-free environment, pollination will have to be done by hand, which is labour-intensive, and will this result in the produce costing more?

And talking about costs, we all know that urban land is far more expensive that farm land, and the cost of creating such a concept and powering up a farmscraper for lights, controlling ambient temperatures and the like, will not be a cheap exercise. So just how much will this produce cost the consumer? It sounds as if it would cost them far more than what they could expect to pay for conventionally grown food. Controlling the environment within these buildings with regards to lighting, temperature, pollination and the arrangement of plants will all be important factors for success.

What is the Future for Vertical Farming?

Will vertical farming ever take off? We are at least 5 - 10 years away from such a concept. We still have enough land to feed the masses in most countries around the world, and we haven't reached crunch point just yet. However, I certainly think that the concept needs to be given serious consideration, especially as what is being proposed is not outlandish.

With cost factors being the major drawback, once cheaper solutions can be found in the construction of these farmscrapers, traditional farming may one day be revolutionized. We may see traditional farmers working in conjunction with inner city farmers in a supporting capacity, to farm organically some of the few crops that perhaps cannot feasibly be grown in a farmscraper environment.

Vertical Gardening for those with Small Spaces

For those of you who wish to grow vegetables in small spaces, vertical gardening now makes perfect sense. You can grow tomatoes, cucumbers and even pumpkins vertically maximising the area you have. See these videos on vertical gardening for more ideas.
