Lockdown lifts Delhi’s air quality

      HEADLINES:

Lockdown lifts Delhi’s air quality to a 5-year high

      WHY IN NEWS:

CPCB data shows pollution fell with cities recording a ‘good’ on AQI

SYLLABUS COVERED: GS 3:Air Pollution : AQI

      ISSUE: 

The ongoing lockdown has pushed pollution levels in Delhi to a 5-year low and, across India, the number of cities that recorded ‘good’ on the air quality index (AQI) jumped from 6 — on March 16 — to 30 as on March 29, according to data from the Central Pollution Control Board.

 

  • PM 2.5, the most dangerous pollutant, measured at the pollution monitoring station in Anand Vihar, New Delhi.
  • PM 2.5 had ranged from 72-187g/m³ during the corresponding period last year, and 72-171g/m³ in 2018.
  • In 2016, it spanned 49-116g/m³, station data on the website of the CPCB shows.

JANATA CURFEW REPORT

  • The CPCB in a report on the impact of the ‘Janata curfew’ on March 22, said that on the day before, AQI was ‘Moderate (101-250)’ in Delhi.
  • “Overall, up to 44% reduction in PM10 levels was observed in Delhi during March 22-23, 2020, compared to previous day.
  • The PM2.5 reduction was 8% on the curfew day but declined to 34% next day owing to negligible combustion activities on March 22-23, 2020, in and around the city,”.

The key factor that triggered the decline was :

  • The number of on-road vehicles, which contributed to a 51% reduction in NOx levels.
  •  32% reduction in carbon monoxide levels during March 22-23 as compared to March 21.
  • Delhi and other regions of the Indo Gangetic Plains generally tend to have better air quality in March, aided by consistent wind and sunlight, which help flush out pollutants.
Research studies have attributed the key sources of PM2.5 in summer to be: dust and construction activities (35%), transport sector (20%) and industry (20%).

LOCKDOWN EFFECT

  • During the lockdown PM10 and PM2.5 levels were reduced by about 35-40%.
  • The cessation of industries contributed to this reduction by 10%, vehicles 10-15% and dust another 10-15%, the organisation calculated.

      IASbhai WINDUP: 

High emission levels in Lucknow and Guwahati were noted for PM2.5, attributable to ‘local’ combustion related activities.

As on March 29, no city was under ‘Poor’ AQI (251-300) category.

Google publishes data on people’s movements

Google publishes data on people’s movements

      WHY IN NEWS:

Users travel information in 131 countries to aid health officials

SYLLABUS COVERED: GS 3:Technology

      ISSUE: 

Alphabet Inc’s Google has published charts showing how the coronavirus has brought hard-hit Italy to a standstill, led to runs on grocery stores around the world and prompted a stark drop in movement of people.

In India, visits to retail and recreation locations dropped by 77%.

KEY POINTS:

  • The analysis of location data from billions of Google users’ phones is the largest public data set available to help health authorities assess if people are abiding with government orders issued to rein in the virus.
  • The reports on users’ movements in 131 countries will be made available on a special website and will “chart movement trends over time by geography”, according to a post on one of Google’s blogs.
  • Trends will display “a percentage point increase or decrease in visits” to locations like parks, shops, homes and places of work, not “the absolute number of visits,”.

For example:

  • In France, visits to restaurants, cafes, shopping centres, museums or theme parks have plunged by 88% from their normal levels, the data showed.
  • Italy and Spain, two of the hardest-hit countries, both saw visits to retail and recreation locations such as restaurants and movie theaters plunge 94%.
  • The U.K. had declines of more than 80% while India, which went into a sudden 21-day lockdown on March 25, was also notable at 77%.

‘NO IDENTIFIABLE DATA’

No “personally identifiable information,” such as an individual’s location, contacts or movements, will be made available, the post said.

The reports will also employ a statistical technique that adds “artificial noise” to raw data, making it harder for users to be identified.

ARTIFICIAL NOISE :

The purpose of generating artificial noise, whether intentional or not, may vary, depending on what is considered noise in a particular context. It can be used to experiment on a subject by controlling the frequency or amplitude of the artificial noise to ascertain how the subject interacts with external stimulation.

      IASbhai WINDUP: 

Like the detection of traffic jams or traffic measurement Google Maps, the new reports will use “aggregated, anonymised” data from users who have activated their location history.
