Expected Questions on Environment December 2018 - NTA NET/UPSC

Dr. Manishika Jain discusses Expected Questions on Environment 2018 for NTA NET Paper 1 Part 1 of 4

  • Satellite mission, called ICESat-2 should provide more precise information on how these frozen surfaces are being affected by global warming.

Background of ICESat-2

  • ICESat-2 is follow-on project.

  • Original spacecraft flew in 2000s & pioneered laser measurement of height of polar glaciers & sea-ice from space.

  • ICESat-2’s Advanced Topographic Laser Altimeter System (ATLAS) measures height by timing how long it takes individual light photons to travel from spacecraft to Earth & back.

  • Satellite mission has 4 science objectives:

  • Measure melting ice sheets & investigate how this effects sea level rise.

  • Measure & investigate changes in mass of ice sheets & glaciers.

  • Estimate & study sea ice thickness.

  • Measure height of vegetation in forests & other ecosystems worldwide.

  • ICESat-2 will improve upon NASA’s 15-year record of monitoring change in polar ice heights.

  • It started in 2003 w/1st ICESat mission & continued in 2009 w/NASA’s Operation Ice Bridge, airborne research campaign that kept track of accelerating rate of change.

  • New observational technologies of ICESat-2 will advance knowledge of how ice sheets of Greenland & Antarctica contribute to sea level rise.

Petroleum Minister Laun. SATAT Initiative to Promote Compressed Bio-Gas as an Alternative

  • Ministry of Petroleum & Natural Gas has launched Sustainable Alternative towards Affordable Transportation (SATAT) aimed at providing sustainable alternative towards affordable transportation.
  • Initiative was launched with PSU Oil Marketing Companies (OMCs i. e. IOC, BPCL, and HPCL).

SATAT Initiative

  • Initiative has potential to boost availability of more affordable transport fuels, better use of agricultural residue, cattle dung, & municipal solid waste.

  • This initiative provides additional revenue source to farmers.

  • It will benefit vehicle-users as well as farmers & entrepreneurs.

  • Expression of Interest (EoI) are invited from potential entrepreneurs to set up Compressed Bio-Gas (CBG) production plants & make available biogas in market for use in automotive fuels.

Env. Ministry, World Bank Release Report on Strengthening Forest Fire Management in the Country

  • Ministry of Environment & Forests & Climate Change (MoEFCC) & World Bank Report have jointly released report on Strengthening Forest Fire Management in Country.
  • Report discusses policies on forest fire prevention & management (FFPM) at national, state & local levels.

  • It provides recommendations on 5 broad themes:

  • Policy

  • Institutions and capacity

  • Technology

  • Community engagement

  • Data and information

  • It has analysed patterns & trends of forest fires in India & looks at national & international best practices in FFPM.

Significance of Report

  • Report is significant in light of released Intergovernmental Panel on Climate Change (IPCC) special report that explores possibilities of keeping global temperature rise w/I 1.50 C to prevent catastrophic impacts due to unchecked temperature rise.

  • Its findings are crucial for India’s own commitment under Nationally Determined Contributions (NDCs) to create additional carbon sink of 2.5 to 3 billion tons of CO2 equivalent thru additional forest & tree cover by 2030.

  • It is expected to be key input in issuing national policy on Forest Fire Prevention & Management (FFPM).

  • MoEFCC issued national guidelines on FFPM in 2000, but these are no longer being implemented.

Second Generation (2G) Ethanol Bio-Refinery

  • Foundation stone for 2nd Generation (2G) Ethanol Bio-refinery of Bharat Petroleum Corporation Limited being set up at Baulsingha village, Bhatli Tehsil, Bargarh ditrict, Odisha was laid by Governor of Odisha.
  • Bio-refinery, 1st of its kind to be set up, will have capacity to produce 3 cr. litres of fuel grade Ethanol annually using Rice straw as feedstock.

  • Ethanol produced from this plant will be blended w/Petrol.

About Biofuels and Its Importance:

  • National Biofuel Policy of India 2018 targets 20 % Ethanol blending to Petrol by 2030.

  • Due to non-availability of Ethanol, current Ethanol blending in Petrol is abt 3 to 4%.

  • Bargarh Bio-Refinery will utilize about 2 lakh tons of Rice straw annually as feedstock. It will be sourced from nearby locations like Bhati, Ambabhona, Sohela, Burla, Lakhanpur, etc.

  • Bio-Refineries will contribute to cleaner environment due to usage of waste Rice straw for Ethanol production thereby reducing waste straw burning in fields.

  • Plant is based on Zero-liquid discharge plant technology where all water will be recycled back into plant.

  • Project will help improve socio-economic conditions of farmers due to additional income from sale of Rice straw to bio-refinery.

  • This will generate employment for approx 1200 persons (both direct & indirect) during construction, operation of plant & supply chain managements of biomass.

Government Launches Air Quality Warning System in Delhi to Combat Air Pollution

  • Union Environment Minister launched Air Quality Early Warning System for Delhi Region. System is designed w/help of American & Finnish models to predict extreme air pollution levels.
  • There is decrease in detection of fire incidents as per satellite mapping in Haryana & Punjab.

Objectives of the System

  • System is launched by Union Govt. in Delhi, keeping in view city’s deteriorating air quality. Associated website is launched along w/it.

  • System will help combat air pollution in National Capital by getting information 2 - 5 days in advance. It will give signs for necessary actions.

Air Quality Index in Delhi

  • Air Quality in New Delhi was 204 on 14th Oct. , 2018.

  • City’s air quality usually breaches ‘severe’ zone, when AQI reading shoots up to 5 times above safe limit, in November.

  • On 9th Nov. , 2017, AQI shot up to 486 on scale of 0 - 500, underscoring conditions that prompted Delhi govt. to declare public health emergency & describe Delhi as ‘gas chamber’.

Measures Taken to Reduce Air Pollution in Delhi

  • Delhi Govt. rolled out its emergency action plan - Graded Response Action Plan (GRAP) for 2nd year in row.

  • Under emergency action plan, stringent measures will be implemented such as ban on diesel generator (DG) sets in Delhi.

  • In November 2017, schools were shut when air quality turned ‘severe’ for more than week.

Background of Air Quality Index

  • In May, Delhi was declared world’s most polluted city, according to air quality data compiled by WHO for megacities w/population of 14 million or more.

  • Greater Cairo in Egypt was adjudged 2nd most polluted city, Bangladesh’s capital Dhaka was placed 3rd, Mumbai 4th & Beijing 5th.

  • New measures including installation of early warning system in capital have helped it become better equipped to fight air pollution in 2018.

Declaring SAI Stadia as “Plastic Free Zones”

  • Ministry of Youth Affairs & Sports are celebrating Swachhata Pakhwada from 1st to 15th August, 2018 under Swachh Bharat Mission Programme of Ministry of Drinking Water & Sanitation.

Department of Sports Has Taken 2 Major Initiatives:

    • Jawaharlal Nehru Stadium

    • Major Dhyan Chand National Stadium

    • Indira Gandhi Stadium Complex

    • Dr. Karni Singh Shooting Range

    • Dr. SPM Swimming Pool Complex

  • 2nd Initiative: Giving Swachhata Rank to these Stadia on implementation of Swachhata activities carried out during Swachhata Pakhwada based on following parameters:

    • Cleanliness of premises

    • Sanitization standard of toilets complex/stadia

    • Functioning level of drainage system in premises

    • Drinking water facilities

    • Tree plantation & maintenance of its growth

    • Proper trimming of existing trees/plants, etc. in premises

    • Waste management system/facilities

    • Involvement of complex/stadia in Swachhta activities of neighbouring areas of complex.

    • Replacement of old lamps w/LED lights.

  • Swachhata Pakhwada started in April 2016 w/objective of bringing fortnight of intense focus on issues & practices of Swachhata by engaging GOI Ministries/Departments in their jurisdictions.
