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.

Stephen Hawking believes Technology could end Poverty and Disease, says Artificial Intelligence could be the Worst or Best things for Humanity

Hawking said everyone has a role to play in making sure that this generation and the next are fully engaged with the study of science at an early level to create “a better world for the whole human race.”

Lisbon, November 7, 2017 : Technology can hopefully reverse some of the harm caused to the planet by industrialization and help end disease and poverty, but artificial intelligence (AI) needs to be controlled, physicist Stephen Hawking said on Monday.

Hawking, a British cosmologist who was diagnosed with motor neuron disease aged 21, said technology could transform every aspect of life but cautioned that artificial intelligence poses new challenges.

He said artificial intelligence and robots are already threatening millions of jobs — but this new revolution could be used to help society and for the good of the world such as alleviating poverty and disease.

“The rise of AI could be the worst or the best thing that has happened for humanity,” Stephen Hawking said via telepresence at opening night of the 2017 Web Summit in Lisbon that is attended by about 60,000 people.

“We simply need to be aware of the dangers, identify them, employ the best possible practice and management and prepare for its consequences well in advance.”

Hawking’s comments come during an escalating debate about the pro and cons of artificial intelligence, a term used to describe machines with a computer code that learns as it goes.

Silicon Valley entrepreneur Elon Musk, who is chief executive of electric car maker Tesla Inc and rocket company SpaceX, has warned that AI is a threat to humankind’s existence.

But Microsoft co-founder Bill Gates, in a rare interview recently, told the WSJ Magazine that there was nothing to panic about.

Stephen Hawking said everyone has a role to play in making sure that this generation and the next are fully engaged with the study of science at an early level to create “a better world for the whole human race.”

“We need to take learning beyond a theoretical discussion of how AI should be, and take action to make sure we plan for how it can be,” said Stephen Hawking, who communicates via a cheek muscle linked to a sensor and computerized voice system.

“You all have the potential to push the boundaries of what is accepted, or expected, and to think big. We stand on the threshold of a brave new world. It is an exciting — if precarious — place to be and you are the pioneers,” he said. (VOA)

4 Ships Banned From All Ports For Violating North Korea Sanctions

The U.N. Security Council has banned all nations from allowing four ships that transported prohibited goods to and from North Korea to enter any port in their country.

Hugh Griffiths, head of the panel of experts investigating the implementation of U.N. sanctions against North Korea, announced the port bans at a briefing to U.N. member states on Monday. A North Korean diplomat attended the hour-long session.

Griffiths later told several reporters that “this is the first time in U.N. history” that the Security Council committee monitoring sanctions against Pyongyang has prohibited ships from entering all ports.

He identified the four cargo ships as the Petrel 8, Hao Fan 6, Tong San 2 and Jie Shun.

According to MarineTraffic, a maritime database that monitors vessels and their moments, Petrel 8 is registered in Comoros, Hao Fan 6 in St. Kitts and Nevis, and Tong San 2 in North Korea. It does not list the flag of Tong San 2 but said that on Oct. 3 it was in the Bohai Sea off north China.

Griffiths said the four ships were officially listed on Oct. 5 “for transporting prohibited goods,” stressing that this was “swift action” by the sanctions committee following the Aug. 6 Security Council resolution that authorized port bans.

That resolution, which followed North Korea’s first successful tests of intercontinental ballistic missiles capable of reaching the United States, also banned the country from exporting coal, iron, lead and seafood products. Those goods are estimated to be worth over $1 billion – about one-third of the country’s estimated $3 billion in exports in 2016.

The Security Council unanimously approved more sanctions on Sept. 11, responding to North Korea’s sixth and strongest nuclear test explosion on Sept. 3.

These latest sanctions ban North Korea from importing all natural gas liquids and condensates, and cap its crude oil imports. They also prohibit all textile exports, ban all joint ventures and cooperative operations, and bars any country from authorizing new work permits for North Korean workers-key sources of hard currency for the northeast Asian nation.

Both resolutions are aimed at increasing economic pressure on the Democratic People’s Republic of Korea – the country’s official name – to return to negotiations on its nuclear and missile programs.

Griffiths told U.N. diplomats that the panel of experts is getting reports that the DPRK “is continuing its attempts to export coal” in violation of U.N. sanctions.

“We have as yet no evidence whatsoever of state complicity, but given the large quantities of money involved and the excess capacity of coal in the DPRK it probably comes as no surprise to you all that they’re seeking to make some money here,” he said.

Griffiths said the panel is “doing our very best to monitor the situation and to follow up with member states who maybe have been taken advantage of by the tactics deployed by DPRK coal export entities.”

As for joint ventures and cooperative arrangements, Griffiths said the resolution gives them 120 days from Sept. 11 to close down.

But “in a number of cases, the indications are that these joint ventures aren’t shutting down at all but are on the contrary expanding _ and therefore joint ventures is a major feature of the panel’s current investigations,” he said.

Griffiths also asked all countries to pay “special attention” to North Korea’s Mansudae Overseas Project Group of Companies, also known as the Mansudae Art Studio, which is on the sanctions blacklist and subject to an asset freeze and travel ban.

According to the sanctions listing, Mansudae exports North Korea workers to other countries “for construction-related activities including for statues and monuments to generate revenue for the government of the DPRK or the (ruling) Workers’ Party of Korea.”

Griffiths said Mansudae “has representatives, branches and affiliates in the Asia-Pacific region, all over Africa and all over Europe.” Without elaborating, he added that “they’re doing an awful lot more than producing statues in Africa.” (voa)

Will Robots Take Your Job? 70 Per cent of Americans Say No

A report issued by the education company Pearson, Oxford University, and the Nesta Foundation found that just one in five workers are in occupations that will shrink by 2030

Washington, October 8, 2017 : Most Americans believe their jobs are safe from the spread of robots and automation, at least during their lifetimes, and only a handful says automation has cost them a job or loss of income.

Still, a survey by the Pew Research Center also found widespread anxiety about the general impact of technological change. Three-quarters of Americans say it is at least “somewhat realistic” that robots and computers will eventually perform most of the jobs currently done by people. Roughly the same proportion worry that such an outcome will have negative consequences, such as worsening inequality.

“The public expects a number of different jobs and occupations to be replaced by technology in the coming decades, but few think their own job is heading in that direction,” Aaron Smith, associate director at the Pew Research Center, said.

The Pew Research Center in Washington, D.C. on July 6, 2005, is the author of a 2017 study looking at the spread of automation and robotics in the workplace.

More than half of respondents expect that fast food workers, insurance claims processors and legal clerks will be mostly replaced by robots and computers during their lifetimes. Nearly two-thirds think that most retailers will be fully automated in 20 years, with little or no human interaction between customers and employers.

Americans’ relative optimism about their own jobs might be the more accurate assessment. Many recent expert analyses are finding less dramatic impacts from automation than studies from several years ago that suggested up to half of jobs could be automated.

Skills will need to be updated

A report issued by the education company Pearson, Oxford University, and the Nesta Foundation found that just one in five workers are in occupations that will shrink by 2030.

Many analysts increasingly focus on the impact of automation on specific tasks, rather than entire jobs. A report in January from the consulting firm McKinsey concluded that less than 5 percent of occupations were likely to be entirely automated. But it also found that in 60 percent of occupations, workers could see roughly one-third of their tasks automated.

That suggests workers will need to continually upgrade their skills as existing jobs evolve with new technologies.

Few have lost jobs to automation

Just 6 percent of the respondents to the Pew survey said that they themselves have either lost a job or seen their hours or incomes cut because of automation. Perhaps not surprisingly, they have a much more negative view of technology’s impact on work. Nearly half of those respondents say that technology has actually made it harder for them to advance in their careers.

Contrary to the stereotype of older workers unable to keep up with new technology, younger workers — aged 18 through 24 — were the most likely to say that the coming of robots and automation had cost them a job or income. Eleven percent of workers in that group said automation had cut their pay or work hours. That’s double the proportion of workers aged 50 through 64 who said the same.

The Pew survey also found widespread skepticism about the benefits of many emerging technologies, with most Americans saying they would not ride in a driverless car. A majority are also not interested in using robots as caregiver for elderly relatives.

Self-driving cars

Thirty percent of respondents said they think self-driving cars would actually cause traffic accidents to increase, and 31 percent said they would stay roughly the same. Just 39 percent said they thought accidents would decline.

More than 80 percent support the idea of requiring self-driving cars to stay in specific lanes.

The survey was conducted in May and had 4,135 respondents, Pew said. (VOA)
