Big Data Current Affairs - 2020

National Intelligence Grid will begin operating from December 31, 2020

On 20 November, 2019, it was announced in Lok Sabha that the ambitious National Intelligence Grid (NATGRID) project will begin by December 31. 2020.

National Intelligence Grid

The NATGRID is a counter terrorism Programme. The grid connects databases of core security agencies of India. It utilizes technologies like Big Data to study and analyze huge amounts of data from various intelligence and enforcement agencies. It was first proposed after the Mumbai terror attacks in 2008.


The network collates data from various agencies and ministries of GoI. The data includes credit card transactions, bank account details, tax details, visa, immigration records and air travel.


NATGRID is being implemented in four phases. The first two phases were approved in 2011. However, their implementation slowed down after 2012 due to political reasons. The third and fourth phases required amendments of several laws and hence were delayed. In all, the NATGRID has never seen an effective implementation so far. Unlike NCTC and NIA, the NATGRID will simply act as a tool to the security agencies.

It also faced several oppositions in terms of privacy and leakage of confidential personal information.

October 7: World Habitat Day

The World Habitat Day is organized by the United Nations. The organization has designated the first Monday of every October to commemorate the day.

Theme: Frontier Technologies as an innovative tool to transform waste to wealth.

The theme is built based on last year’s theme “Municipal Solid Waste Management”.

The focus of this year World Habitat Day (WHD) is to promote contribution of FRONTIER TECHNOLOGIES towards sustainable waste management that helps to achieve SDG 11.

The SDGS 11 is about building inclusive, safe, resilient and sustainable cities.


  • The 2019 WHD is to be observed in Mexico

Significance of Frontier Technologies

  • The Frontier technologies include robotics, automation, renewable energy technologies, Artificial Intelligence and bio technologies. Some of the top frontier technologies are Big Data Analysis, Sustainable polymers, Internet of Things, Artificial Intelligence, 3D printing, Nanotechnology, renewable energy technologies, drones and customized satellites.
  • They are technologies that offer potential for cheaper, faster, scalable and easy to use solutions for every day problems. It includes waste management as well.

Significance of the WHD

  • The world’s cities produce 7 to 10 billion tons of waster per year.
  • Low income countries spend around 20% of their budget on waste management. In most of the countries this allocated budget is not sufficient to finance waste and sanitation management systems.
  • In most of the urban areas of developing countries, around 16% of urban dwellers lack access to basic sanitation services.

The lack of waste management has led to air, soil and water pollution that in turn threaten public health. Another biggest challenge is dumping of waste in the oceans. The plastics from these wastes are killing around 100,000 marine animals annually.

The SDG goals 6, 11, 12 and 14  and the Paris Agreement all focus on waste management and considers it as an urgent and issue to be addressed.

How can Frontier technologies help?

  • The use of sustainable polymers reduces waste generation and also reduces the need of recyclable wastes
  • The technology of 3D printing has the potential of creating less waste during production.
  • Smart bins using AI can help in garbage sorting.

UN Habitat Strategic Plan 2020 – 2023

The plan reinforces all the global agendas on waste management. Under the plan the UN is to focus on Frontier Technologies that help in safe, resilient, sustainable and smart cities.
