How and where is our food being grown and produced? Will there be grown enough food to supply the ever-growing urban centres? These are questions that we need to ask ourselves in the present with regard to the future outlook.
Currently, city supplies on average are only three days, but in case of a big storm that isolates the entire city… What can and should we do…?!
There are several advantages of combining smart-farming with smart cities, such as fresher food available, less need of transportation, more opportunities in recycling water and the ability to use open spaces in a better way. Today, cities are getting to look greener and greener. Rooftop gardens and greenhouses are not strange anymore.
Two typical types of farming are currently seen in cities: Aeroponic and hydroponic farming. Aeroponic farming is the process of growing food and plants in a mist or air environment without using any soil or another aggregate medium. Whereas hydroponic farming that constitutes of growing plants without soil, but using mineral nutrient solutions to feed the plants in water. Aerponic farming is already widely in use, using Newark (New Yersey) as an example. Aerofarms is conquering the world with their aeroponic farms that (in their opinion) contribute to: ‘fresh, great tasting and highly nutritious food’. One of their farming advantages is that they are having a closed loop system that is enabling water reduction of 95% in comparison to field farming and 40% reduction when compared to hydroponics. Some say that indoor farming is amounting for 10 times the amount compared to outside farming (on the field); That’s heck of a lot salads for these smart-cities!!
However, Aerofarms is doing a good job but Vertical Farming will be unable in feeding the world’s fastest growing urban populations! Smart farming needs more development to gain sustainable and sufficient fresh food in the nearby area of the population. Maybe those vertical farms will be able to get linked to rooftops, supermarkets, restaurants and even homes, making the whole chain more efficient in many ways.
To conclude, the smart city is meeting the smart farm and the other way around. Only if those are combined, ultimate benefits can be gained.
