Vertical farming: A big leap towards sustainable farming

The vertical farming reduces the dependency and cost of skilled labourers, weather conditions, soil fertility or high water usage.Nearly 30% profitability can be obtained through this technique.

What Is Vertical Farming?

Vertical farming is the technique of producing food in stacked layers or on vertically inclined surfaces which comprises of new automated farms. It requires less natural dependency and helps in reducing the dependency and cost of skilled labourers, weather conditions, soil fertility or high water usage.

What Vertical Farming Does?

  • Modern day vertical farming includes controlled environment agriculture technology i.e. CEA technology. All other environmental factors can be controlled using this technique. Techniques such as augmentation of sunlight by artificial lightning and by metal reflectors are also used for producing a similar greenhouse-like effect.
  • Vertical farms is a pesticide-free technique which requires much less input than traditional farming methods and gives much more output.
  • Farms embedded with this technique uses artificial lighting systems that facilitate enhanced photosynthesis. LEDs are placed near plants to impart specific wavelengths of lights for more photosynthesis. This enhances productivity.
  • Aeroponic mist’ is another technique used which helps in supplying the proper amount of oxygen and other soil nutrients. This makes the nature of growth more robust.

Advantages & Benefits of vertical farming techniques are as follows:

  • Vertical farming enables Reliable harvest. With it, the term ‘seasonal crops’ becomes obsolete. Irrespective of sunlight, pests or extreme temperature, these farms can easily meet the demand of contractors anytime.
  • Minimum overheads – Nearly 30% profitability can be obtained through this growing technique.
    • Low energy usage – Use of computerized LEDs by giving proper wavelength reduces energy to a great extent.
    • Low labour costs – Fully automated technique so no skilled labours are required.
    • Low water usage – Controlled transpiration technique are used. It requires only 10% of the water usage of traditional technique.
    • Reduced washing and processing – No pests control required. Reduces the cost of damage washing.
    • Reduced transportation costs – Can be established in any location. This reduces the cost of transportation and usage.
  • Increased growing area – Enables cost effective farming and provides nearly 8 times more productivity.
  • Maximum crop yield – Irrespective of other geographic factors Vertical Farming technique gives maximum yield.
  • A wide range of crops – Growth of crop are maintained by an intensive database which enables them to grow a wide range of crops such as Baby spinach, Baby rocket, Basil, Tatsoi, Leaf lettuce.
  • Fully integrated technology – All environmental factors are closely monitored and are maintained in an optimal range.
    • Optimum air quality
    • Optimum nutrient and mineral quality
    • Optimum water quality
    • Optimum light quality

All these technologies used leads to a dramatic shift in plant growth rates and their yields.

Trump views 50 years out of date, may trigger disruptive trade war: Paul Krugman

Criticising the US President Donald Trump for his protectionists policies, Nobel Laureate Paul Krugman on Saturday accused President Trump of not taking his jobs seriously. Following the protectisists measures taken by the US President, there could be “risks of disruptive trade war”, he said.

President Donald Trump has pledged to avoid any new foreign business deals during his term in office.

“He does not take the job seriously. He doesn’t say to himself that I am the most important official in the world; I have better do my homework for understanding the issue. ..He just goes that these are my gut feeling and hires people who make him feel good…that is a frightening prospect,” Krugman said responding to a query on his perception on Trump. On the economic issues President Trump’s gut feelings are “protectionist” and his views of America were “50 years out of date”.

“He wants America a heavy industrial country in the way it was when he was a young man. That is not just going to happen but he attempts to make it happen, which is extremely disruptive to America and to the global as a whole,” Nobel Laureate said. Krugman said he was until recently optimistic that Trump’s protectionist policies would not see the light of the day.

“Until about two weeks ago, I was quite optimistic that it would not happen. The reason was not because the President would get good economic advice but because the US businesses are invested in a globalised economy. All the investments the businesses have made is based upon the assumptions that the open trading system would continue. There is an enormous amount of fiscal capital and a large number of jobs are dependent on these value chains,” he said at the News18 Rising India Summit here.

Krugman further said: “I had assumed the influence of these business communities would be sufficient… that it would not happen. I am less optimistic now…we have seen reasonably sensible Economic Council Head was fired, completely irrational tariff (was) imposed on steel and aluminium.”

The President also called for more mental institutions and hospitals in addition to the idea of arming teachers.

According to him, immediate issue is going to be confrontation not with China, but with Europe as the “steel tariffs” will hit Europe. He said there are possible risks of “disruptive global trade war”.

Speaking on Chinese economy he said, “China is a financial crisis waiting to happen. China is a widely unbalanced economy…the country is sustaining itself with a credit bubble that is waiting to burst…There is a significant risk of Chinese bubble burst.”
