  • Urban Heat Islands in India

     

    A recent study from IIT Kharagpur called “Anthropogenic forcing exacerbating the urban heat islands in India” noted that the relatively warmer temperature in urban areas, compared to suburbs, may contain potential health hazards due to heat waves apart from pollution.

    About the study

    • The research did study the difference between urban and surrounding rural land surface temperatures, across all seasons in 44 major cities from 2001 to 2017.
    • It found evidence of mean daytime temperature of surface urban heat island (UHI Intensity) going up to 2 degrees C for most cities, as analysed from satellite temperature measurements in monsoon and post monsoon periods.
    • Other researchers from elsewhere have also noticed similar rise in daytime temperatures in Delhi, Mumbai, Bengaluru, Hyderabad and Chennai.

    What is an Urban Heat Island?

    • An urban heat island (abbreviated as UHI) is where the temperature in a densely populated city is as much as 2 degrees higher than suburban or rural areas.
    • This happens because of the materials used for pavements, roads and roofs, such as concrete, asphalt (tar) and bricks, which are opaque, do not transmit light, but have higher heat capacity and thermal conductivity than rural areas, which have more open space, trees and grass.
    • Trees and plants are characterised by their ‘evapotranspiration’— a combination of words wherein evaporation involves the movement of water to the surrounding air, and transpiration refers to the movement of water within a plant and a subsequent lot of water through the stomata (pores found on the leaf surface) in its leaves.
    • Grass, plants and trees in the suburbs and rural areas do this. The lack of such evapotranspiration in the city leads to the city experiencing higher temperature than its surroundings.

    Latent impacts

    • UHI s also decrease air quality in the cities, thanks to pollution generated by industrial and automobile exhaust, higher extent of particulate matter and greater amounts of dust than in rural areas.
    • Due to this higher temperature in urban areas, the UHI increases the colonization of species that like warm temperatures, such as lizards and geckos.
    • Insects such as ants are more abundant here than in rural areas; these are referred to as ectotherms.
    • In addition, cities tend to experience heat waves which affect human and animal health, leading to heat cramps, sleep deprivation and increased mortality rates.
    • UHIs also impact nearby water bodies, as warmer water (thanks to the pavements, rooftops and so on) is transferred from the city to drains in sewers, and released into nearby lakes and creeks, thus impairing their water quality.

    Control of UHIs and mitigation

    • Industrialization and economic development are vital to the country, but the control of UHIs and their fallouts are equally vital. Towards this, several methods are being, and can be, tried.
    • One of them is to use greener rooftops, using light-coloured concrete (using limestone aggregates along with asphalt (or tar) making the road surface greyish or even pinkish (as some places in the US have done); these are 50% better than black, since they absorb less heat and reflect more sunlight.
    • Likewise, we should paint rooftops green, and install solar panels there amidst a green background.
    • The other is to plant as many trees and plants as possible

    Why plant more trees?

    Relevant to the present context are:

    • they combat climate change; clean the surrounding air by absorbing pollutant gases (NXOy, O3, NH3, SO2, and others) and trapping particulates on their leaves and bark;
    • they cool the city and the streets; conserve energy (cutting air-conditioning costs by 50%); save water and help prevent water pollution; help prevent soil erosion; protect people and children from UV light;
    • they offer economic opportunities; bring diverse group of people together; encourage civic pride by giving neighborhoods a new identity; mask concrete walls, thus muffling sounds from streets and highways, and eye-soothing canopy of green; and the more a business district has trees, more business follows.

  • Conservation plan for Konark Sun Temple

    A plan to restore and preserve the nearly 800-year-old Konark Sun Temple in Odisha would be drawn up soon. Among the potential choices before the government would be to fill in more sand or to remove all the sand andput in place alternate support.

    Konark Sun Temple

    • Konark Sun Temple is a 13th-century CE Sun temple at Konark about 36 kilometres northeast from Puri on the coastline of Odisha, India.
    • The temple is attributed to king Narasinga Deva I of the Eastern Ganga Dynasty about 1250 CE.
    • Dedicated to the Hindu Sun God Surya, what remains of the temple complex has the appearance of a 100-foot (30 m) high chariot with immense wheels and horses, all carved from stone.
    • Once over 200 feet (61 m) high, much of the temple is now in ruins, in particular the large shikara tower over the sanctuary; at one time this rose much higher than the mandapa that remains.
    • The structures and elements that have survived are famed for their intricate artwork, iconography, and themes, including erotic kama and mithuna scenes.
    • Also called the Surya Devalaya, it is a classic illustration of the Odisha style of Architecture or Kalinga Architecture.
    • Declared a UNESCO world heritage site in 1984 it remains a major pilgrimage site for Hindus, who gather here every year for the Chandrabhaga Mela around the month of February.

    Earlier restoration efforts

    • It had been filled with sand and sealed by the British authorities in 1903 in order to stabilize the structure, a/c to ASI.
    • A scientific study was carried out by the Roorkee-based Central Building Research Institute from 2013 till 2018 to ascertain the temple’s structural stability as well as the status of the filled-in sand.
    • The sand filled in over 100 years ago had settled, leading to a gap of about 17 feet.  However the structure was found to be stable.

  • ‘Future of Earth, 2020’ Report

     

    The “The Future of Earth, 2020” Report was recently released.

    About the report

    • The report is released by the South Asia Future Earth Regional Office, Divecha Centre for Climate Change, Indian Institute of Science.
    • The report was prepared with the aim of reducing carbon footprint and halting global warming below 2 degree Celsius by 2050.

    Highlights of the report

    • Five global risks that have the potential to impact and amplify one another in ways that may cascade to create global systemic crisis have been listed by report.
    • It listed the following as five global risks:
    1. failure of climate change mitigation and adaptation
    2. extreme weather events
    3. major biodiversity loss and ecosystem collapse
    4. food crises; and
    5. water crises
    • Offering examples of how the interrelation of risk factors play a role, scientists say extreme heatwaves can accelerate global warming by releasing large amounts of stored carbon from affected ecosystems, and at the same time intensify water crises and/ or food scarcity.
    • The loss of biodiversity also weakens the capacity of natural and agricultural systems to cope with climate extremes, increasing our vulnerability to food crises, they point out.

  • In news: Two-child Norm

    A Rajya Sabha MP has introduced a Private Member’s Bill on two-child norms.

    Key propositions of the Bill

    • Essentially, the Bill aims to amend the Constitution in order to incentivise limiting families to two children by offering tax concessions, priority in social benefit schemes and school admissions, among other things.
    • It proposes incentives in taxation, education and employment for people who limit their family size to two children.

    Article 47A

    • The Bill has sought the incorporation of a new provision, Article 47A in Part IV of the Constitution, to withdraw all concessions from people who fail to adhere to the “small-family” norm.
    • Article 47A says the following:

     “47A. The State shall promote small family norms by offering incentives in taxes, employment, education etc. to its people who keep their family limited to two children and shall withdraw every concession from and deprive such incentives to those not adhering to small family norm, to keep the growing population under control.”

    Note: Article 47 of the Indian Constitution is one of the DPSP  which directs the State to raise the level of nutrition and the standard of living and to improve public health as among its primary duties and, in particular, the State shall endeavour to bring about prohibition of intoxicating drinks and drugs which are injurious to health.

    Why such Bill?

    • The Bill’s Statement of Object and Reasons states that the fact that India’s population has already crossed 125 crore is “really frightening”.
    • It goes on to say that India’s population has doubled in the last 40 years and that it is expected to unseat China as the world’s most populous nation in the next couple of decades.
    • Despite the fact that we have framed a National Population Control Policy, we are the second most populous country in the world.
    • Further, the population explosion will cause “many problems” for our future generations.
    • The Bill also makes a reference to “overburdened” natural resources that are overexploited because of overpopulation.

    Statewide policies relating to two-child norms

    Assam Cabinet has recently decided that those with more than two children will be ineligible for government jobs from 2021. Other states with similar norms:

    Rajasthan: For government jobs, candidates who have more than two children are not eligible for appointment.

    Madhya Pradesh: The state follows the two-child norm since 2001. Under Madhya Pradesh Civil Services (General Condition of Services) Rules, if the third child was born on or after January 26, 2001, one becomes ineligible for government service. The rule also applies to higher judicial services.

    Telangana: Under Section 19 (3) read with Sections 156 (2) and 184 (2) of Telangana Panchayat Raj Act, 1994, a person with more than two children shall be disqualified from contesting election. However, if a person had more than two children before May 30, 1994, he or she will not be disqualified.  The same sections in the Andhra Pradesh: AP Panchayat Raj Act, 1994, apply to Andhra Pradesh, where a person having more than two children shall be disqualified from contesting election.

    Gujarat: In 2005, the government amended the Gujarat Local Authorities Act. The amendment disqualifies anyone with more than two children from contesting elections for bodies of local self-governance — panchayats, municipalities and municipal corporations.

    Maharashtra: The Maharashtra Zilla Parishads And Panchayat Samitis Act disqualifies people who have more than two children from contesting local body elections (gram panchayats to municipal corporations). The Maharashtra Civil Services Rules, 2005 states that a person having more than two children is disqualified from holding a post in the state government. Women with more than two children are also not allowed to benefit from the Public Distribution System.

    Karnataka: The Karnataka (Gram Swaraj and Panchayat Raj) Act, 1993 does not bar individuals with more than two children from contesting elections to local bodies like the gram panchayat. The law, however, says that a person is ineligible to contest “if he does not have a sanitary latrine for the use of the members of his family”.

    Odisha: The Odisha Zilla Parishad Act bars those individuals with more than two children from contesting.

  • Species in news: Thanatotheristes

     

    Scientists have found that a dinosaur fossil, found in Alberta in Canada in 2010, belongs to a new species of tyrannosaur. They have named it Thanatotheristes, which means “reaper of death”.

    Thanatotheristes

    • Tyrannosaurs were one of the largest meat-eating dinosaurs to have ever lived, with very large and high skulls, and the best known among them is the Tyrannosaurus rex, celebrated in the Jurassic Park series.
    • The 79-million-year-old fossil that the researchers have found is the oldest tyrannosaur known from northern North America.
    • Thanatotheristes preyed on large plant-eating dinosaurs such as the horned xenoceratops and the dome-headed colepiochephale.
    • The research suggests that tyrannosaurs did not have one general body type; rather different tyrannosaur species evolved distinct body sizes, skull forms and other such physical features.
    • The fossil specimen is important to understand the Late Cretaceous period, which is the period when tyrannosaurs roamed the Earth.

  • [pib] National List of Intangible Cultural Heritage

    Sangeet Natak Akademi (SNA) is preparing the National List of Intangible Cultural Heritage.

    National List of Intangible Cultural Heritage

    • SNA is an autonomous organization under the Ministry of Culture is the nodal agency for the Scheme for ‘Safeguarding the Intangible Cultural Heritage and Diverse Cultural Traditions of India’.
    • As of now, SNA is collaborating with Zonal Cultural Centers of Ministry, collating and preparing a list of ICH elements for National List of Intangible Cultural Heritage.
    • List of ICH elements is being compiled and at least 100 elements will be documented by March, 2020 and the aim is to document at least 20 new elements in ICH list every year.
    • Along with this establishment of an ‘Indian Institute for Culture’ is at conceptual stage and a mission called National Culture Mapping portal is being conceptualized for aggregating art forms and artists. It is in pilot phase.

  • Why emergency response units are needed to ensure safety of sanitation workers

    • The Maharashtra government has directed all civic bodies in the state to set up Emergency Response Sanitation Units (ERSUs) to ensure safeguards for sanitation workers who clean manholes and sewers.
    • This move is in response to the multiple cases which were reported of workers dying from suffocation or inhalation of hazardous gases.

    PEMSR ACT, 2013

    • The Prohibition of Employment as Manual Scavengers and their Rehabilitation (PEMSR) Act came into force in 2013.
    • The law prohibits employing manual scavengers, manual cleaning of sewers and septic tanks without protective equipment and construction of insanitary latrines.
    • Those violating the law and getting sewers and septic tanks cleaned without protective equipment can face imprisonment of up to two years or a fine of up to Rs 2 lakh, or both.
    • Repeat offenders will face imprisonment of up to five years or a fine of up to Rs 5 lakh, or both.

    The Supreme Court judgment

    • While hearing a case on manual scavenging in 2014, the Supreme Court had stated, “If the practice of manual scavenging has to be brought to an end, and also to prevent future generations from the inhuman practice… rehabilitation of manual scavengers will need to include steps to avoid sewer deaths.”
    • The court had said that making a sanitation worker enter sewer lines without safety gear should be a crime even in emergency situations.
    • In such instances, if a sanitation worker died due to the unsafe conditions, a compensation of Rs 10 lakh has to be given to the family of the deceased, stated the court.
    • The court had also directed authorities to identify the family members of sanitation workers who died while cleaning manholes and septic tanks since 1993, and give a compensation of Rs 10 lakh to them.

    Directives by National Commission for Scheduled Castes

    • To ensure effective implementation of the law banning manual scavenging, the commission issued various directives.
    • It said workers have to be fully equipped with safety apparatus and oxygen masks in case they have to clean sewers manually.
    • A first information report has to be lodged against officials or contractors responsible for sending a worker to clean sewers manually, without proper gear.
    • The commission also made it mandatory for all municipal corporations to get an insurance policy of Rs 10 lakh per worker, as per the Supreme Court’s directions.
    • The employers, in this case the civic bodies, will have to pay the policy premium.

    Emergency Response Sanitation Unit (ERSU)

    • In its directive on the setting up of ERSUs, the state government said the municipal commissioner of the civic body concerned will be the Responsible Sanitation Authority (RSA).
    • The ERSU should be headed by a senior civic officer and other civic officers should be on the ERSU advisory board to decide the standard operating procedure (SoP) for workers who enter manholes for cleaning purposes.
    • The civic body will also have to set up a dedicated toll-free number for the ERSU. The unit will impart training to sanitation workers.
    • Only workers trained and certified by an ERSU will be able to clean sewers, but the priority will be on using machines to get such work done.
    • In case a worker dies while cleaning a sewer, the civic body will have to hold an inquiry and register a police complaint.

    Workshop on creating awareness on the issue

    • All civic bodies have been asked to hold workshops to raise awareness on this issue in their respective jurisdictions.
    • The workshops are going to focus on latest technology for cleaning sewers and septic tanks, and the final objective is to find a way to clean septic tanks or manholes with machines.
    • The workshops will have sessions on laws pertaining to sanitation workers, the establishment of ERSUs and their roles, presentations on the latest equipment, machines and protective gear.
    • Sanitation workers, NGOs, social organisations, housing society members and government officials have to participate in the workshops.

  • Thwaites Glacier

     

    In the Antarctic floats a massive glacier, roughly the size of Britain, whose melting has been a cause of alarm for scientists over the years. Now, a new study has pinned the cause of the melting to the presence of warm water at a vital point beneath the glacier.

    Thwaites Glacier

    • The Thwaites Glacier is 120 km wide at its broadest, fast-moving and melting fast over the years.
    • Because of its size (1.9 lakh square km), it contains enough water to raise the world sea level by more than half a metre.
    • Studies have found the amount of ice flowing out of it has nearly doubled over the past 30 years. Today, Thwaites’s melting already contributes 4% to global sea level rise each year.
    • It is estimated that it would collapse into the sea in 200-900 years. Thwaites is important for Antarctica as it slows the ice behind it from freely flowing into the ocean.
    • Because of the risk it faces — and poses — Thwaites is often called the Doomsday Glacier.

    What has the new study found?

    • A 2019 study had discovered a fast-growing cavity in the glacier.
    • More recently researchers detected warm water at a vital point below the glacier.
    • Scientists dug a 600-m-deep and 35-cm-wide access hole, and deployed an ocean-sensing device called Icefin to measure the waters moving below the glacier’s surface.
    • The study reported water at just two degrees above freezing point at Thwaites’s “grounding zone” or “grounding line”.

    What is the grounding line?

    • The grounding line is the place below a glacier at which the ice transitions between resting fully on bedrock and floating on the ocean as an ice shelf.
    • The location of the line is a pointer to the rate of retreat of a glacier.
    • When glaciers melt and lose weight, they float off the land where they used to be situated. When this happens, the grounding line retreats.
    • That exposes more of a glacier’s underside to seawater, increasing the likelihood it will melt faster.
    • This resulted in the glacier speeding up, stretching out, and thinning, causing the grounding line to retreat ever further.

  • [pib] Ease of Living Index and Municipal Performance Index 2019

    The surveys to determine the Ease of Living Index (EoLI) and Municipal Performance Index (MPI) 2019 has been initiated by the Ministry of Housing & Urban Affairs. Both these indices are designed to assess the quality of life of citizens in 100 Smart Cities and 14 other Million Plus Cities.

    Municipal Performance Index

    • With the MPI 2019, the Ministry has sought to assess the performance of municipalities based on five enablers namely Service, Finance, Planning, Technology and Governance.
    • These have been further divided into 20 sectors which will be evaluated across 100 indicators.
    • This will help Municipalities in better planning and management, filling the gaps in city administration, and improving the liveability of cities for its citizens.

    Ease of Living Index

    • EOLI is aimed at providing a holistic view of Indian cities – beginning from the services provided by local bodies, the effectiveness of the administration, the outcomes generated through these services in terms of the liveability within cities and, finally, the citizen perception of these outcomes.
    • The key objectives of the EOL Index are four-folds, viz.
    1. Generate information to guide evidence-based policy making;
    2. Catalyse action to achieve broader developmental outcomes including the SDG;
    3. Assess and compare the outcomes achieved from various urban policies and schemes; and
    4. Obtain the perception of citizens about their view of the services provided by the city administration.
    • For the first time, as part of the EOLI Assessment, a Citizen Perception Survey is being conducted on behalf of the Ministry (which carries 30% of the marks of the Ease of Living Index).
    • This is a very important component of the assessment exercise as it will help in directly capturing perception of citizens with respect to quality of life in their cities.
    • This survey, which is being administered both online and offline, has commenced from 1st February 2020 and will continue till 29th February 2020.
    • The offline version involving face-to-face interviews will commence on the 1st of February and will run parallel to the on-line versions.

  • Explained: Practice of Female Genital Mutilation (FGM)

     

    Every year, February 6 is observed as the International Day of Zero Tolerance for Female Genital Mutilation (FGM).  As per the WHO, globally, over 200 million girls alive today have suffered FGM in over 30 countries.

    Female Genital Mutilation

    • FGM is the name given to procedures that involve altering or injuring the female genitalia for non-medical or cultural reasons.
    • It is recognised internationally as a violation of human rights and the health and integrity of girls and women.
    • Most girls and women who have undergone FGM live in sub-Saharan Africa and the Arab States, but it is also practiced in some countries in Asia, Eastern Europe and Latin America.
    • According to the United Nations Population Fund (UNFPA), while the exact origins of the practice remain unclear, it seems to have predated Christianity and Islam.
    • It says that some Egyptian mummies display characteristics of FGM.
    • Significantly, the ancient Greek historian Herodotus has claimed that in the fifth century BC, the Phoenicians, the Hittites and the Ethiopians practised circumcision.

    Why is Female Genital Mutilation practiced?

    • Depending on the region, there can be various reasons why FGM is performed. The UNFPA has categorised the reasons into five categories —
    1. psycho-sexual reasons (when FGM is carried out as a way to control women’s sexuality, “which is sometimes said to be insatiable if parts of the genitalia, especially the clitoris, are not removed);
    2. sociological or cultural reasons (when FGM is seen as part of a girl’s initiation into womanhood and an intrinsic part of a community’s cultural heritage);
    3. hygiene and aesthetic reasons (this may be the reason for those communities that consider the external female genitalia as ugly and dirty);
    4. religious reasons (the UNFPA maintains that while FGM is not endorsed by Christianity or Islam, “supposed” religious doctrines may be used to justify the practice);
    5. socio-economic factors (in some communities FGM is a pre-requisite for marriage, especially in those communities where women are dependent on men economically).
    • Other reasons cited by the WHO include- an attempt to ensure women’s premarital virginity since FGM is believed to reduce libido,  and therefore believed to help her resist extramarital sexual acts.
    • FGM may also be associated with cultural ideals of feminity and modesty.

    Economic cost of FGM

    • Beyond the immense psychological trauma it entails, FGM imposes large financial costs and loss of life.
    • In 2018, a study on FGM in India said that the practice was up to 75 per cent across the Bohra Muslim community.
    • The economic costs of treating health complications arising out of FGM amount to roughly $1.4 billion for 2018 for 27 countries where FGM is performed.
    • If the prevalence remains the same, the amount is expected to rise up to $2.3 billion by 2047.

    FGM in India

    • According to the aforementioned study, the reasons for FGM referred to as “Khafd” in India include continuing an old traditional practice, adhering to religious edicts, controlling women’s sexuality and abiding by the rules stated by the religious clergy.
    • It also states that the issue first rose to prominence in India because of two international legal cases on FGM against practising Bohras in Australia and the US.
    • In 2018, a bench of then CJI Dipak Misra referred a petition seeking a ban on FGM among Dawoodi Bohra girls to a five-judge Constitution Bench.
    • The Dawoodi Bohra community, on the other hand, maintained that the practice should be allowed since the Constitution grants religious freedom under Article 25.
