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.

People of Lao Find Social Media For News Most Trustworthy

The number of the country’s social media users is now projected to reach 2.7 million or 39 percent of the population this year, according to the report.

Lao residents are increasingly abandoning state-controlled news sources and turning more to the internet and social media to get news they can trust, sources in the communist Southeast Asian country say.

Facebook and the internet also provide news more quickly and feature live videos, a young woman living in Xayaburi province in the country’s north told RFA’s Lao Service on April 23.

“Lao TV just reads the news and doesn’t show the real thing,” RFA’s source said, speaking on condition of anonymity.

“Increasingly aware of the restrictions imposed on the official media, Laotians are turning to the Internet and social media,” RSF said in its report.

“For example, when there was a flood in Attapeu province, social media very quickly reported the number of deaths,” the young woman said. “But the Lao government was not really open about any of this,” she said.

Also speaking to RFA, a man in Savannakhet province in the south of Laos said he now reads Facebook to get news not previously screened by authorities.

“[Lao] TV provides only restricted news and information, for example news about drug trafficking and other news about the country,” the man said, also speaking on condition he not be named.

“The stories broadcast on TV aren’t clear, and are screened ahead of time by the authorities,” the man said, adding, “The internet is not restricted, and the authorities can’t control the information we find on it.”

Both sources told RFA that they frequently check their smart phones when looking for news and other updated information whenever they can get a clear signal, looking also at the social media platforms Line, WhatsApp, and WeChat.

‘Absolute control’

In an annual report released earlier this month, Paris-based media watchdog Reporters Without Borders (RSF) gave Laos a ranking of 171, close to the bottom of a 180-country survey of press freedoms worldwide, saying that the country’s ruling Lao People’s Revolutionary Party (LPRP) “exercises absolute control over the media.”

“Increasingly aware of the restrictions imposed on the official media, Laotians are turning to the Internet and social media,” RSF said in its report.

“But use of online news and information platforms is held back by a 2014 decree under which Internet users who criticize the government and the Marxist-Leninist LPRP can be jailed,” the press freedoms group said.

Speaking to RFA, a Lao government official dismissed the RSF report, saying, “We have a socialist media, and we serve a socialist regime, the Party and the government.  I don’t believe in their ranking.”

“Our government doesn’t force us to do anything,” he said. “For example, if the government tells us not to publish a story, we simply don’t do it.”

The number of people using social media in Laos is expected to surge this year, as telecom operators compete with each other to offer better services, a report released at the beginning of April by the state-controlled Lao National Internet Centre shows.
