  • Waste Management – SWM Rules, EWM Rules, etc

    Ban on Single-Use Plastics

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Single use plastics

    Mains level: Need for plastic waste management

    Since July 1, 2022, India has banned the manufacture, import, stocking, distribution, sale, and use of single-use plastics (SUP) items with low utility and high littering potential.

    What are single-use plastics?

    • Single-use plastics, often also referred to as disposable plastics, are commonly used for plastic packaging and include items intended to be used only once before they are thrown away or recycled.
    • These include, among other items, grocery bags, food packaging, bottles, straws, containers, cups and cutlery.

    Why are single-use plastics harmful?

    • The purpose of single-use plastics is to use them once or for a short period of time before disposing of them. Plastic waste has drastic impacts on the environment and human health.
    • There is a greater likelihood of single-use plastic products ending up in the sea than reusable ones.

    SUP ban in India

    • India has taken resolute steps to mitigate pollution caused by littered single-use plastics.
    • A number of items are banned, including earbuds with plastic sticks, balloon sticks, plastic flags, candy sticks, ice cream sticks, polystyrene (thermocol) for decorations, plates, cups, glasses, cutlery such as forks, spoons, knives, straws etc.
    • India has also banned plastic or PVC banners less than 100 micron, stirrers, etc.

    What is the impact on the environment?

    [A] Solid Waste generation

    • The disposal of plastics is one of the least recognized and most highly problematic areas of plastic’s ecological impact.
    • Ironically, one of plastic’s most desirable traits: its durability and resistance to decomposition, is also the source of one of its greatest liabilities when it comes to the disposal of plastics.
    • A very small amount of total plastic production (less than 10%) is effectively recycled; the remaining plastic is sent to landfills.
    • It is destined to remain entombed.

    [B] Ecological Impact

    (i) Groundwater and soil pollution

    • Plastic is a material made to last forever, and due to the same chemical composition, plastic cannot biodegrade; it breaks down into smaller and smaller pieces.
    • When buried in a landfill, plastic lies untreated for years.
    • In the process, toxic chemicals from plastics drain out and seep into groundwater, flowing downstream into lakes and rivers.
    • The seeping of plastic also causes soil pollution and have now started resulting in presence of micro plastics in soil.

    (ii) Water Pollution

    • The increased presence of plastic on the ocean surface has resulted in more serious problems.
    • Since most of the plastic debris that reaches the ocean remains floating for years as it does not decompose quickly, it leads to the dropping of oxygen level in the water.
    • It has severely affected the survival of marine species.
    • When oceanic creatures and even birds consume plastic inadvertently, they choke on it which causes a steady decline in their population.
    • In addition to suffocation, ingestion, and other macro-particulate causes of death in larger birds, fish, and mammals.

    [C] Health Hazards

    • Burning of plastic results into formation of a class of flame retardants called as Halogens.
    • Collectively, these harmful chemicals are known to cause the following severe health problems: cancer, neurological damage, endocrine disruption, birth defects and child developmental disorders etc.

    Ban elsewhere

    • India is not the first country to ban single-use plastics.
    • Bangladesh became the first country to ban thin plastic bags in 2002; New Zealand banned plastic bags in July 2019.
    • China had issued a ban on plastic bags in 2020 with a phased implementation.
    • As of July 2019, 68 countries have plastic bag bans with varying degrees of enforcement.

    What are the plastic waste management rules in India?

    • With effect from September 30, 2021 India has the Plastic Waste Management Amendment Rules, 2021.
    • It prohibited the manufacture, import, stocking, distribution, sale, and use of plastic carry bags whose thickness is less than 75 microns.
    • From December 31, 2022, plastic carry bags whose thickness is less than 120 microns will be banned.
    • It means that the ban does not cover all plastic bags; however, it requires the manufacturers to produce plastic bags thicker than 75 microns which was earlier 50 microns.
    • As per the notification, the standard shall be increased to 120 microns in December this year.

    What is the role of the manufacturer?

    • In addition, the Ministry of Environment, Forests, and Climate Change notified the Plastic Waste Management Amendment Rules, 2022 on February 16, 2022.
    • Extended Producer Responsibility (EPR) is the responsibility of a producer for the environmentally sound management of the product until the end of its life.
    • The guidelines provide a framework to strengthen the circular economy of plastic packaging waste, promote the development of new alternatives to plastic packaging and provide the next steps for moving towards sustainable plastic packaging by businesses.

    Various steps taken

    • The Indian government has taken steps to promote innovation and create an ecosystem for accelerated adoption and availability of alternatives across the country.
    • To ensure the effective enforcement of the ban, national and State-level control rooms will be established, as well as special enforcement teams for the purpose of checking the illegal sale and use of single-use plastics.
    • To prevent the movement of banned single-use plastic items between States and Union Territories, border checkpoints have been established.
    • In an effort to empower citizens to help curb the plastic menace, the Central Pollution Control Board (CPCB) has launched a grievance redressal application.

    What are the challenges?

    • The ban will succeed only if all stakeholders participate enthusiastically and engage in effective engagement and concerted actions.
    • However, if we look back at our past, almost 25 Indian States previously banned plastic at the state level.
    • However, these bans had a very limited impact in reality because of the widespread use of these items.
    • Now the challenge is to see how the local level authorities will enforce the ban in accordance with the guidelines.
    • Banned items such as earbuds with plastic sticks, plastic sticks for balloons, etc., are non-branded items and it is difficult to find out who the manufacturer is and who is accountable.

    Way forward

    • The consumer needs to be informed about the ban through advertisements, newspaper or TV commercials, or on social media.
    • In order to find sustainable alternatives, companies need to invest in research and development.
    • The solution to the plastic pollution problem is not the responsibility of the government alone, but of industries, brands, manufacturers and most importantly consumers.
    • Finding alternatives to plastic seems a little difficult, however, greener alternatives to plastic may be considered a sustainable option.
    • For example, compostable and bio-degradable plastic, etc., may be considered as an option.
    • While the total ban on the use of plastic sounds a great idea, its feasibility seems difficult at this hour, especially in the absence of workable alternatives.

  • Food Processing Industry: Issues and Developments

    Mandatory requirements for Packaged Commodities

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Rule for Packaged Commodities

    Mains level: Read the attached story

    The Department of Consumer Affairs, Legal Metrology Division has notified a draft amendment to the Legal Metrology (Packaged Commodities) Rules 2011 making some compulsions.

    Discrepancies over Packaged Commodities

    • The Division has observed that many manufacturers/packagers/importers do not clearly label necessary declarations or prime constituents on the front of packaged commodities.
    • It is common for consumers to assume that brands’ claims are accurate, but such claims are usually misleading.
    • Such disclosure are deemed essential in order to protect consumer rights.

    What are the mandatory provisions under the Legal Metrology (Packaged Commodities) Rules, 2011?

    • It is mandatory under the Rules, to ensure a number of declarations, such as the:
    1. Name and address of the manufacturer/packer/importer,
    2. Country of origin,
    3. Common or generic name of the commodity,
    4. Net quantity,
    5. Month and year of manufacture
    6. Maximum Retail Price (MRP) and
    7. Consumer care information.
    • As a consumer-oriented policy, all pre-packaged commodities should also be inspected.
    • Rule 9(1)(a) provides that the declaration on the package must be legible and prominent.
    • The consumers’ ‘right to be informed’ is violated when important declarations are not prominently displayed on the package.

    What are the proposed amendments?

    • As many blended food and cosmetic products are sold on the market, the key constituents need to be mentioned on the product packaging.
    • Additionally, the front side of the package must contain the percentage of the composition of the unique selling proposition (USP).
    • Also, packages displaying key constituents must display a percentage of the content used to make the product.
    • The new amendments has suggested that at least two prime components should be declared on the package’s front side along with the brand name.
    • Currently, manufacturers list the ingredients and nutritional information only on the back of the packaging.
    • This declaration must also include the percentage/quantity of the USPs of the product in the same font size as the declaration of the USPs. However, mechanical or electrical commodities are excluded from this sub-rule.

    Back2Basics: Consumer Rights

    Consumer right is an insight into what rights consumer holds when it comes to the seller who provides the goods.

    In general, the consumer rights in India are listed below:

    (1) Right to Safety

    • Means right to be protected against the marketing of goods and services, which are hazardous to life and property.
    • The purchased goods and services should not only meet their immediate needs, but also fulfil long term interests.
    • Before purchasing, consumers should insist on the quality of the products as well as on the guarantee of the products and services. They should preferably purchase quality marked products such as ISI, AGMARK, etc.

    (2) Right to be Informed

    • Means right to be informed about the quality, quantity, potency, purity, standard and price of goods so as to protect the consumer against unfair trade practices.
    • Consumer should insist on getting all the information about the product or service before making a choice or a decision.
    • This will enable him to act wisely and responsibly and also enable him to desist from falling prey to high pressure selling techniques.

    (3) Right to Choose

    • Means right to be assured, wherever possible of access to variety of goods and services at competitive price. In case of monopolies, it means right to be assured of satisfactory quality and service at a fair price.
    • It also includes right to basic goods and services. This is because unrestricted right of the minority to choose can mean a denial for the majority of its fair share.

    (4) Right to be Heard

    • Means that consumer’s interests will receive due consideration at appropriate forums. It also includes right to be represented in various forums formed to consider the consumer’s welfare.

    (5) Right to Seek redressal

    • Means right to seek redressal against unfair trade practices or unscrupulous exploitation of consumers. It also includes right to fair settlement of the genuine grievances of the consumer.
    • Consumers must make complaint for their genuine grievances. Many a times their complaint may be of small value but its impact on the society as a whole may be very large.

    (6) Right to Consumer Education

    • Means the right to acquire the knowledge and skill to be an informed consumer throughout life.
    • Ignorance of consumers, particularly of rural consumers, is mainly responsible for their exploitation.

    Rajpath, Central Vista lawns renamed ‘Kartavya Path’

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Kartavya Path

    Mains level: Read the attached story

    Rajpath and Central Vista Lawns in the national capital will now be known as “Kartavya Path”, the New Delhi Municipal Council (NDMC) announces.

    Updating to Kartavya Path

    • The entire stretch and the area from the Netaji statue under the Grand Canopy to the Rashtrapati Bhavan will be known as Kartavya Path.
    • Kartavya Path, which will be opened to the public at the end of the official function, will exhibit landscapes, lawns with walkways, added green spaces, refurbished canals, amenity blocks, improved signages and vending kiosks.
    • New pedestrian underpasses, improved parking spaces, new exhibition panels, and upgraded night lighting are some other features that will enhance the public experience.
    • It also includes a number of sustainability features like solid waste management, storm-water management, recycling of used water, rainwater harvesting, water conservation and energy-efficient lighting systems, among others.

    Kingsway to Rajpath

    • Called Kingsway during British rule, the three-km stretch was built as a ceremonial boulevard by Edwin Lutyens and Herbert Baker, the architects of New Delhi, more than a hundred years ago.
    • The capital of the Raj moved to New Delhi from Calcutta in 1911, and construction continued for several years thereafter.
    • Lutyens conceptualised the modern imperial city centred on a “ceremonial axis”, which was named Kingsway in honour of the then Emperor of India, George V.
    • He visited Delhi during the Durbar of 1911, where he formally proclaimed the decision to move the capital.
    • The nomenclature followed that of the Kingsway in London, an arterial road built in 1905, which was named in honour of King Edward VII, the father of George V.
    • Following Independence, the road was given its Hindi name, Rajpath, on which the Republic Day parades took place over the decades that followed.

    Why sudden renaming?

    • During his address from the Red Fort on August 15, Modi had stressed on the abolition of symbols of colonialism.
    • The new name and look of Rajpath, as well as the installation of the 28-foot statue of Netaji under the Grand Canopy under which a statue of George V once stood, are meant to represent that spirit of the proud new India.

    Significance of all recent event

    • The construction of the Central Vista Redevelopment Project began in February 2021, with the new Parliament building and redevelopment of the Central Vista Avenue in the first phase.
    • The aim is to build an iconic avenue that truly befits the New India, the government has said about the Rs 608 crore Central Vista Avenue project.
    • It symbolizes a shift from erstwhile Rajpath being an icon of power to Kartavya Path being an example of public ownership and empowerment.

  • Interstate River Water Dispute

    In news: Sutlej-Yamuna Link (SYL) Canal

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: SYL Canal

    Mains level: Interstate water disputes

    The Supreme Court drew an assurance from the State of Punjab that it will meet the Haryana counterpart within this month to discuss the construction of the Sutlej-Yamuna Link (SYL) Canal which has been languishing for two decades.

    Why in news?

    • The observations came after the Centre complained that Punjab had “refrained” from coming to the negotiating table to engage in talks with Haryana over the issue.
    • The construction of Punjab’s portion of the canal had led to militant attacks in the 1980s.
    • The issue had also been a political thorn for successive governments in Punjab, so much so that it led to the State’s unilateral enactment of the controversial Punjab Termination of Water Agreements Act of 2004.
    • This law was, however, struck down by a Constitution Bench in 2016, dashing the hopes of Punjab’s farmers to reclaim lands acquired for the SYL canal project.

    About Sutlej-Yamuna Link (SYL) Canal

    • Satluj Yamuna Link Canal or SYL as it is popularly known, is an under-construction 214-kilometer long canal in India to connect the Sutlej and Yamuna rivers.

    What is the SYL canal issue?

    • At the time of reorganization of Punjab in 1966, the issue of sharing of river waters between both the states emerged.
    • Punjab refused to share waters of Ravi and Beas with Haryana stating it was against the riparian principle.
    • Before the reorganization, in 1955, out of 15.85 MAF of Ravi and Beas, the Centre had allocated 8 MAF to Rajasthan, 7.20 MAF to undivided Punjab, 0.65MAF to Jammu and Kashmir.
    • Out of 7.20 MAF allocated, Punjab did not want to share any water with Haryana.
    • In March 1976, when the Punjab Reorganization Act was implemented, the Centre notified fresh allocations, providing 3.5 MAF To Haryana.

    Inception of the canal project

    • Later, in 1981, the water flowing down Beas and Ravi was revised and pegged at 17.17 MAF, out of which 4.22 MAF was allocated to Punjab, 3.5 MAF to Haryana, and 8.6 MAF to Rajasthan.
    • Finally, to provide this allocated share of water to southern parts of Haryana, a canal linking the Sutlej with the Yamuna, cutting across the state, was planned.
    • Finally, the construction of 214-km SYL was started in April 1982, 122 km of which was to run through Punjab and the rest through Haryana.
    • Haryana has completed its side of the canal, but work in Punjab has been hanging fire for over three decades.

    Why has the SYL canal come up again now?

    • The issue is back on centre stage after the Supreme Court directed the CMs of Punjab and Haryana to negotiate and settle the SYL canal issue.
    • The apex court asked for a meeting at the highest political level to be mediated by the Centre so that the states reach a consensus over the completion of the SYL canal.
    • The meeting remained inconclusive with the Centre expressing the view that the construction of the SYL canal should be completed. But Punjab CM refused categorically.

    Punjab’s resentment with the project

    • The dispute is based on the bloody history around the SYL canal. The trouble-torn days of terrorism in Punjab started in the early 1980s when work on the SYL started.
    • Punjab feels it utilized its precious groundwater resources to grow the crop for the entire country and should not be forced to share its waters as it faces desertification.
    • It is feared that once the construction of the canal restarts, the youth may start feeling that the state has been discriminated against.
    • The Punjab CM fears Pakistan and secessionist organisations could exploit this and foment trouble in the state.

    Water crisis in Punjab

    • Punjab is facing severe water crisis due to over-exploitation of its underground aquifers for the wheat/paddy monocycle.
    • According to the Central Underground Water Authority’s report, its underground water is over-exploited to meet the agriculture requirements in about 79 per cent area of the state.
    • Out of 138 blocks, 109 are “over-exploited”, two are “critical” five are “semi-critical” and only 22 blocks are in “safe” category.

    Punjab expects a new tribunal

    • The state wants a tribunal seeking a fresh time-bound assessment of the water availability.
    • The state has been saying that till date there has been no adjudication or scientific assessment of Punjab river waters.

  • Primary and Secondary Education – RTE, Education Policy, SEQI, RMSA, Committee Reports, etc.

    What is the PM SHRI Scheme?

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: PM Shri Schools

    Mains level: Read the attached story

    Prime Minister has announced that under the PM SHRI Scheme, as many as 14,500 schools will be “upgraded” across India to showcase the components of the National Education Policy, 2020.

    What is the PM SHRI scheme?

    • According to the Ministry of Education, the centrally sponsored scheme will be called PM SHRI Schools (PM Schools for Rising India).
    • Under it, as many as 14,500 schools across states and Union Territories will be redeveloped to reflect the key features of the NEP, 2020.
    • The plan was first discussed with the education ministers of states and UTs during a conference organised by the Ministry of Education in June at Gandhinagar in Gujarat.
    • While there are exemplary schools like Navodaya Vidyalayas, Kendriya Vidyalayas, the PM SHRI will act as “NEP labs”.

    What are the key features of NEP in school education?

    • The NEP envisages a curricular structure and teaching style divided into various stages – foundational, preparatory, middle and secondary.
    • The foundational years (pre-school and grades I, II) will involve play-based learning.
    • At the preparatory level (III-V), light textbooks are to be introduced along with some formal classroom teaching. Subject teachers are to be introduced at the middle level (VI-VIII).
    • The secondary stage (IX-XII) will be multidisciplinary in nature with no hard separation between arts and sciences or other disciplines.

    What is a centrally sponsored scheme?

    • A centrally sponsored scheme is one where the cost of implementation is likely to split in the 60:40 ratio among the Union government and the states/Union Territories.
    • For instance, the mid-day meal scheme (PM Poshan) or the PM Awas Yojana are examples of centrally sponsored schemes.
    • In the case of the Northeastern states, Himachal Pradesh, Uttarakhand, Jammu and Kashmir and UTs without legislatures, the Centre’s contribution can go up to 90 per cent.

    How will PM SHRI schools be different from Kendriya Vidyalayas or Jawahar Navodaya Vidyalayas?

    • Kendriya Vidyalayas or Jawahar Navodaya Vidyalayas come entirely under the Centre’s Ministry of Education. They are fully funded by the Union government under Central Sector Schemes.
    • While KVs largely cater to children of Union government employees posted in states and UTs, JNVs were set up to nurture talented students in rural parts of the country.
    • In contrast, PM SHRI schools will be an upgrade of existing schools run by the Centre, states, UTs and local bodies.
    • This essentially means that PM SHRI schools can either be KVs, JNVs, state government schools or even those run by municipal corporations.

    Where will the PM SHRI schools come up?

    • The Centre has not yet released the list of schools that have been chosen for this purpose.
    • It has however announced that the PM SHRI schools will also “offer mentorship” to other schools in their vicinity.
    • These schools will be equipped with modern infrastructure including labs, smart classrooms, libraries, sports equipment, art room etc.
    • It shall also be developed as green schools with water conservation, waste recycling, energy-efficient infrastructure and integration of organic lifestyle in curriculum.

  • Industrial Sector Updates – Industrial Policy, Ease of Doing Business, etc.

    Services PMI flags rebound in August

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Purchasing Managers’ Index

    Mains level: Not Much

    The services sector rebounded in August from a four-month low in July and created the most jobs in 14 years as input cost pressures eased to the slowest pace in 11 months, as per S&P Global India Services Purchasing Managers’ Index (PMI), which expanded to 57.2 last month, from July’s 55.5.

    Purchasing Managers’ Index (PMI)

    • PMI is an indicator of business activity — both in the manufacturing and services sectors.
    • It is a survey-based measure that asks the respondents about changes in their perception of some key business variables from the month before.
    • It is calculated separately for the manufacturing and services sectors and then a composite index is constructed.
    • The PMI is compiled by IHS Markit based on responses to questionnaires sent to purchasing managers in a panel of around 400 manufacturers.

    How is the PMI derived?

    • The PMI is derived from a series of qualitative questions.
    • Executives from a reasonably big sample, running into hundreds of firms, are asked whether key indicators such as output, new orders, business expectations and employment were stronger than the month before and are asked to rate them.

    How does one read the PMI?

    • A figure above 50 denotes expansion in business activity. Anything below 50 denotes contraction.
    • Higher the difference from this mid-point greater the expansion or contraction. The rate of expansion can also be judged by comparing the PMI with that of the previous month data.
    • If the figure is higher than the previous month’s then the economy is expanding at a faster rate.
    • If it is lower than the previous month then it is growing at a lower rate.

    What are its implications for the economy?

    • The PMI is usually released at the start of the month, much before most of the official data on industrial output, manufacturing and GDP growth becomes available.
    • It is, therefore, considered a good leading indicator of economic activity.
    • Economists consider the manufacturing growth measured by the PMI as a good indicator of industrial output, for which official statistics are released later.
    • Central banks of many countries also use the index to help make decisions on interest rates.

  • Historical and Archaeological Findings in News

    Pakistan floods may take away Mohenjo Daro’s World Heritage Tag

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Mohenjo Daro

    Mains level: Not Much

    Heavy floods in Pakistan has pushed the archeological site of Mohenjo Daro – near the bank of the Indus river – to the “brink of extinction”.

    What is the news?

    • Pakistan’s Department of Archaeology has said that Mohenjo Daro might be removed from the world heritage list, if urgent attention towards its conservation and restoration is not given.

    About Mohenjo Daro

    • Mohenjo Daro, a group of mounds and ruins, is a 5000-year-old archaeological site located about 80-km off the city of Sukkur.
    • It comprises the remnants of one of two main centres of the ancient Indus Valley Civilisation, the other one being Harappa, located 640 km to the northwest, in Punjab province.
    • Mohenjo Daro, which means ‘mound of the dead’, was one of the oldest cities of the world.
    • Known to be a model planned city of the ancient civilisation, the houses here had bathrooms, toilets and drainage system.
    • The sheer size of the city, and its provision of public buildings and facilities, suggests a high level of social organization.
    • Though in ruins, the walls and brick pavements in the streets are still in a preserved condition.

    How did it came to prominance

    • The ruins of the city remained undocumented for around 3,700 years, until 1920, when archaeologist RD Banerji visited the site.
    • Its excavation started in 1921 and continued in phases till 1964-65.
    • The site went to Pakistan during Partition.

    Other Indus Valley sites

    • The Indus Valley Civilisation spanned much of what is now Pakistan and the northern states of India (Gujarat, Haryana and Rajasthan), even extending towards the Iranian border.
    • Its major urban centres included Harappa and Mohenjo Daro in Pakistan, and Lothal, Kalibangan, Dholavira and Rakhigarhi in India.
    • Mohenjo Daro is considered the most advanced city of its time, with sophisticated civil engineering and urban planning.
    • When the Indus Valley Civilisation went into sudden decline around 19th century BC, Mohenjo Daro was abandoned.

    What next for the site

    • According to media reports, many streets and sewerage drains of the historical ruins have been badly damaged due to the floods.
    • However, the work of removing the sediments deposited due the flooding is still underway.
    • But if this kind of flooding happens again, the heritage site may once again get buried under the ground, archaeologists say.
    • It is expected that UN Secretary General Antonio Guterres will visit the site during his visit to Pakistan on September 11.
    • The visit might provide some clarity on if the site has lost some of its attributes that are necessary for it to retain its prestigious world heritage tag.

    Losing world heritage tag

    • There are around 1,100 UNESCO listed sites across its 167 member countries.
    • Last year, the World Heritage Committee decided to delete the property ‘Liverpool – Maritime Mercantile City’ (UK) from the World Heritage List.
    • This was due to the irreversible loss of attributes conveying the outstanding universal value of the property.
    • Liverpool was added to the World Heritage List in 2004 in recognition of its role as one of the world’s major trading centres in the 18th and 19th centuries – and its pioneering dock technology, transport systems and port management.
    • Before that, the first venue to be delisted by the UNESCO panel was the Arabian Oryx Sanctuary in Oman, in 2007, after concerns over poaching and habitat degradation.
    • Another site to be removed from the World Heritage list in 2009 was Elbe Valley in Dresden, Germany, after the construction of the Waldschloesschen road bridge across the Elbe River.

    Back2Basics: UNESCO World Heritage Sites

    • A World Heritage Site is a landmark or area, selected by the UN Educational, Scientific and Cultural Organization (UNESCO) for having cultural, historical, scientific or other forms of significance, which is legally protected by international treaties.
    • The sites are judged to be important for the collective and preservative interests of humanity.
    • To be selected, a WHS must be an already-classified landmark, unique in some respect as a geographically and historically identifiable place having special cultural or physical significance (such as an ancient ruin or historical structure, building, city, complex, desert, forest, island, lake, monument, mountain, or wilderness area).
    • It may signify a remarkable accomplishment of humanity, and serve as evidence of our intellectual history on the planet.
    • The sites are intended for practical conservation for posterity, which otherwise would be subject to risk from human or animal trespassing, unmonitored/uncontrolled/unrestricted access, or threat from local administrative negligence.
    • The list is maintained by the international World Heritage Program administered by the UNESCO World Heritage Committee, composed of 21 “states parties” that are elected by their General Assembly.

    UNESCO World Heritage Committee

    • The World Heritage Committee selects the sites to be listed as UNESCO World Heritage Sites, including the World Heritage List and the List of World Heritage in Danger.
    • It monitors the state of conservation of the World Heritage properties, defines the use of the World Heritage Fund and allocates financial assistance upon requests from States Parties.
    • It is composed of 21 states parties that are elected by the General Assembly of States Parties for a four-year term.
    • India is NOT a member of this Committee.

    ISRO tests system recoverable rocket ‘Inflatable Aerodynamic Decelerator (IAD)’

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Inflatable Aerodynamic Decelerator (IAD)

    Mains level: Not Much

    The Indian Space Research Organisation (ISRO) has successfully tested a technology that could aid the cost-effective recovery of spent rocket stages and safely land payloads on other planets.

    What is IAD?

    • IAD is a technique used for an atmospheric entry payload.
    • An inflatable envelope and an inflatant (anything that inflates the envelope, like air or helium) make up the inflatable aerodynamic decelerator.
    • While entering the atmosphere, it inflates like a balloon and decelerates the lander.
    • The inflatant is designed to fill the inflatable envelope to a condition such that it surrounds the payload meant to enter the atmosphere of a planet or satellite and causes aerodynamic forces to slow it down.
    • In simpler words, IAD is designed to increase drag upon entering the atmosphere of any planetary body, like Earth, Mars, or even Moon.
    • Its shape is maintained by a closed, gas-pressured body and the inflatant gas is also generated internally. Some versions also use ram air or both.

    How significant is this IAD?

    • Some space agencies, including NASA, have already successfully tested advanced versions of the technology, including the supersonic and hypersonic variants.
    • However, for near future missions of ISRO, the current version that it tested is perfect.
    • Its use was first proposed by NASA more than 50 years ago for planetary entries.

    Minuscule of ISRO’s IAD

    • The IAD tested by ISRO was inflated at an altitude of around 84 km and the sounding rocket’s cargo dropped through the atmosphere on it.
    • It is fitted with a booster motor. It also has a spin rocket that is ejectable.
    • The inflatable structure is made out of Kevlar fabric, which is a very strong synthetic fibre and also heat resistant to withstand atmospheric pressure and temperature changes.
    • On top of it, it’s coated with polychloroprene, an oil and wax resistant rubber, to withstand extreme temperatures.
    • In the inflation system, it uses compressed nitrogen stored in a bottle.
    • It has consistently decreased the payload’s velocity through aerodynamic drag while maintaining the expected trajectory during the test flight.

    Where does ISRO intend to use it?

    • The IAD will help ISRO in performing many space tasks effectively including recovery of spent stages of rockets, for landing payloads on missions to other planetary bodies.
    • This is the first instance where an IAD has been specially created for spent stage recovery.
    • So inter-planetary missions are certainly one aspect that ISRO wishes to explore.

    India’s first Dark Sky Reserve to come up in Ladakh

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Dark Sky Reserve

    Mains level: Not Much

    In a first-of-its-kind initiative, the Department of Science & Technology (DST) has announced the setting up of India’s first dark sky reserve at Hanle in Ladakh in the next three months.

    What is a Dark Sky Reserve?

    • A dark-sky reserve is an area, usually surrounding a park or observatory that is kept free of artificial light pollution.
    • The purpose of a dark sky preserve is generally to promote astronomy.
    • Because different national organizations have worked independently to create their programs, different terms have been used to describe the areas.

    How is it designated?

    • A dark sky reserve is a designation given to a place that has policies in place to ensure that a tract of land or region has minimal artificial light interference.
    • The International Dark Sky Association is a US-based non-profit that designates sites as international dark sky places, parks, sanctuaries and reserves, depending on the criteria they meet.
    • Several such reserves exist around the world but none so far in India.

    Dark Sky Reserve at Hanle

    • Hanle, which is about 4,500 metres above sea level, hosts telescopes and is regarded as one of the world’s most optimal sites for astronomical observations.
    • However, ensuring that the site remains well-suited for astronomy implies keeping the night sky pristine, or ensuring minimal interference to the telescopes from artificial light sources such as electric lights and vehicular lights from the ground.
    • The site will have activities to help in boosting local tourism and economy through interventions of science and technology.

    The Himalayan Chandra Telescope, High Energy Gamma Ray Telescope, Major Atmospheric Cherenkov Experiment Telescope and GROWTH-India are the prominent telescopes located at the Hanle observatory.

    Ideal conditions in India

    • The Indian Astronomical Observatory, the high-altitude station of the IIA, is situated to the north of Western Himalayas, at an altitude of 4,500 metres above mean sea level.
    • Located atop Mt. Saraswati in the Nilamkhul Plain in the Hanle Valley of Changthang, it is a dry, cold desert with sparse human population.
    • The cloudless skies and low atmospheric water vapour make it one of the best sites in the world for optical, infrared, sub-millimetre, and millimetre wavelengths.
