  • Prime Minister’s National Relief Fund (PMNRF)

    Keeping in view the novel coronavirus crisis across the country, various govt. employees, celebrities and political dignitaries are open-heartedly contributing to the PM’s National Relief Fund (PMNRF) to help combat the disease.

    PM’s National Relief Fund (PMNRF)

    • In pursuance of an appeal by the then PM, Pt. Nehru in January, 1948, the Prime Minister’s National Relief Fund (PMNRF) was established with public contributions.
    • It was aimed to assist displaced persons from Pakistan.
    • The resources of the PMNRF are now utilized primarily to render immediate relief to families of those killed in natural calamities like floods, cyclones and earthquakes, etc. and to the victims of the major accidents and riots.
    • Assistance from PMNRF is also rendered, to partially defray the expenses for medical treatment like heart surgeries, kidney transplantation, cancer treatment and acid attack etc.
    • The fund consists entirely of public contributions and does not get any budgetary support.

    Legal status

    • PMNRF has not been constituted by the Parliament.
    • The fund is recognized as a Trust under the Income Tax Act and the same is managed by PM or multiple delegates for national causes.

    Donations

    • PMNRF accepts only voluntary donations by individuals and institutions.
    • Contributions flowing out of budgetary sources of Government or from the balance sheets of the public sector undertakings are not accepted.
    • Conditional contributions, where the donor specifically mentions that the amount is meant for a particular purpose, are not accepted in the Fund.

    Its operation

    • PMNRF operates from the Prime Minister’s Office and does not pay any license fee.
    • PM is the Chairman of PMNRF and is assisted by Officers/ Staff on an honorary basis. Permanent Account Number of PMNRF is AACTP4637Q.

    Tax exemptions

    • PMNRF is exempt under the Income Tax Act, 1961 under Section 10 and 139 for return purposes.
    • Contributions towards PMNRF are notified for 100% deduction from taxable income under section 80(G) of the Income Tax Act, 1961.

  • Protecting Peatlands can help attain climate goals

     

    Peatlands, which play a crucial role in regulating global climate by acting as carbon sinks, are facing degradation and need to be urgently monitored, according to the FAO. 

    What are Peatlands?

    • Peatlands are a type of wetlands that occur in almost every country on Earth, currently covering 3% of the global land surface.
    • The term ‘peatland’ refers to the peat soil and the wetland habitat growing on its surface.
    • They are formed due to the accumulation of partially decomposed plant remains over thousands of years under conditions of water-logging.
    • In these areas, year-round waterlogged conditions slow the process of plant decomposition to such an extent that dead plants accumulate to form peat.
    • Over millennia this material builds up and becomes several metres thick.

    Why are peatlands significant?

    • Large amounts of carbon, fixed from the atmosphere into plant tissues through photosynthesis, are locked away in peat soils, representing a valuable global carbon store.
    • Peatlands are highly significant to global efforts to combat climate change, as well as wider sustainable development goals.
    • The protection and restoration of peatlands are vital in the transition towards a low-carbon and circular economy.

    1) Better sinks of Carbon

    • Damaged peatlands contribute about 10% of greenhouse gas emissions from the land-use sector.
    • CO2 emissions from drained peatlands are estimated at 1.3 gigatonnes of CO2 This is equivalent to 5.6% of global anthropogenic CO2 emissions.
    • However, at the same time, peatlands are the largest natural terrestrial carbon store. Worldwide, the remaining area of near-natural peatland contains more than 550 gigatonnes of carbon.
    • This represented 42% of all soil carbon and exceeds the carbon stored in all other vegetation types, including the world’s forests. This area sequesters 0.37 gigatonnes of CO2 a year.

    2) Vital ecosystem services

    • By regulating water flows, peatlands help minimize the risk of flooding and drought and prevent seawater intrusion.
    • In many parts of the world, peatlands supply food, fibre and other local products that sustain local economies.
    • They also preserve important ecological and archaeological information such as pollen records and human artefacts.
    • Draining peatlands reduces the quality of drinking water due to pollution from dissolved compounds. Damage to peatlands also results in biodiversity loss.

    Other benefits

    • Peatlands occur in different climate zones.
    • While in a tropical climate, they can occur in mangroves, in Arctic regions, peatlands are dominated by mosses. Some mangrove species are known to develop peatland soils under them.
    • Besides climate mitigation, peatlands are important for archaeology, as they maintain pollen, seeds and human remains for a long time in their acidic and water-logged conditions.
    • In many countries, pristine peatlands are important for recreation activities. These areas also support livelihood in the form of pastoralism
    • The vegetation growing on pristine peatlands provide different kinds of fibres for construction activities and handicrafts.
    • Many wetland species produce berries, mushrooms and fruits, often economically important to local communities.
    • Peatlands also provide fishing and hunting opportunities. It is also possible to practise paludiculture or wet agriculture on rewetted peatlands.

    Various threats

    • Their degradation due to drainage, fire, agricultural use and forestry can trigger the release of the stored carbon in a few decades.
    • Peatlands contain 30 per cent of the world’s soil carbon. When drained, these emit greenhouse gases, contributing up to one gigatonne of emissions per year through oxidation.

    Way forward

    • In India, peatlands occupy roughly 320–1,000 square kilometres area.
    • To prevent further degradation, these areas should be urgently mapped and monitored.

  • Species in news: Carissa carandas (the Great Hedge of India)

     

    Carissa carandas, a  multi-utility wild berry, whose thorny plant the British had used to build a barrier through India in the 1870s, has a hitherto unknown wilder cousin in Assam, a new study has revealed.

    Carissa carandas

    • The Carissa carandas was also among several thorny plants the British had grown 140 years ago for a 1,100-mile barrier apparently to enforce taxes and stop the smuggling of salt.
    • It has been used as a traditional herbal medicine for a number of ailments such as diarrhoea, anaemia, constipation, indigestion, skin infections and urinary disorders.
    • The leaves have been used as fodder for silkworms while a paste of its pounded roots serves as a fly repellent.
    • It is better known as karonda in Hindi, kalakkai in Tamil, koromcha in Bengali and karja tenga in Assamese, the Carissa kopilii is threatened by the very river it is named after — Kopili in central Assam.
    • The “sun-loving” plant was distributed sparsely, rooted in rocky crevices along the Kopili riverbed at altitudes ranging from 85-600 metres above sea level.

  • [pib] GreenCo Rating System

     

     

    The Union Ministry of Railways has informed about the applications of Greenco Ratings on Workshops and Production Units of Indian Railways.

    GreenCo Ratings

    • GreenCo Rating is the “first of its kind in the World” holistic framework that evaluates companies on the environmental friendliness of their activities using life cycle approach.
    • Implementation of GreenCo rating provides leadership and guidance to companies on how to make products, services and operations greener.
    • It is developed by Confederation of Indian Industry’s (CII) Sohrabji Godrej Green Business Centre.
    • It has been acknowledged in India’s Intended Nationally Determined Contribution (INDC) document, submitted to UNFCCC in 2015.
    • GreenCo rating is applicable to both manufacturing facilities and service sector units.
    • The rating is implemented at unit or facility level. The unit or facility has to be in operation for a minimum period of 3 years. In case of new plants/ facilities minimum 2 years operation is required.

    Utility

    It helps the industrial units in identifying and implementing various possible measures in terms of energy conservation, material conservation, recycling, utilization of renewable energy, GHG reduction, water conservation, solid and liquid waste management, green cover etc.

  • Dumping of Radioactive Nuclear Waste

    In a controversial move, Japan has decided to dump the radioactive heavy water from the Fukushima nuclear power plant into the Sea.  The dumping of nuclear waste is considered to be the easiest way to get rid of it.

    What is Heavy Water?

    • Heavy water (deuterium oxide) is a form of water that contains a larger than normal amount of the hydrogen isotope deuterium rather than the common hydrogen that makes up most of the hydrogen in normal water.
    • Heavy water is used in certain types of nuclear reactors, where it acts as a neutron moderator to slow down neutrons.
    • Slowed neutrons are more likely to react with the fissile uranium-235 than with uranium-238 which captures neutrons without fissioning.

    Where is Fukushima waste?

    • It is currently being stored in large tanks, but those are expected to be full by 2022.
    • Almost 1.2 million liters of radioactive water from the Fukushima nuclear power plant is to be released into the ocean.
    • The contaminated water has since been used to cool the destroyed reactor blocks to prevent further nuclear meltdowns.

    Hazards of the nuclear contamination

    • Radioactive pollution in the ocean has been increasing globally — and not just since the disaster at Fukushima.
    • Radiation levels in the sea off Fukushima were millions of times higher than the government’s limit of 100 Becquerel.
    • A single Becquerel that gets into our body is enough to damage a cell that will eventually become a cancer cell.
    • Even the smallest possible dose, a photon passing through a cell nucleus, carries a cancer risk. Although this risk is extremely small, it is still a risk.

    Who else dumped radioactive water into oceans?

    The dumping of nuclear waste in drums was banned in 1993 by the London Convention on the Prevention of Marine Pollution. But discharging liquid contaminated with radiation into the ocean is still permitted internationally.

    • The lion’s share of dumped nuclear waste came from Britain and the Soviet Union, figures from the IAEA show.
    • By 1991, the US had dropped more than 90,000 barrels and at least 190,000 cubic meters of radioactive waste in the North Atlantic and Pacific.
    • To this day, around 90% of the radiation in the ocean comes from barrels discarded in the North Atlantic, most of which lie north of Russia or off the coast of Western Europe.

  • Danube-Oder-Elbe Canal

     

    Environmental organisations from across central and Eastern Europe have criticised a major project intending to link three rivers and provide seamless navigation between three of Europe’s peripheral seas, according to a statement.

    Danube-Oder-Elbe Canal

    • For centuries Europe’s rulers have dreamed of construction of a huge Y-shaped canal connecting the Elbe, Oder and Danube rivers, most of which would be on Czech territory.
    • The Canal intends to connect the Danube, Oder and Elbe rivers and thus provide another navigable link from the Black Sea to the North and Baltic Seas.
    • The Main-Danube Canal already provided a navigable connection between the Black Sea and the North Sea.
    • Several hundred kilometres of artificial waterways would have to be built for the canal, according to the statement.
    • Critics have called on the European Commission to ensure that the project be excluded from EU funding, and not be included as part of the Trans-European Transport Network.

  • Explained: Notified Disaster

    The Ministry of Home Affairs has decided to treat COVID-19 as a notified disaster for the purpose of providing assistance under the State Disaster Response Fund (SDRF).

    What is a Disaster?

    According to the Disaster Management Act, 2005 a disaster is defined as-

    • A catastrophe, mishap, calamity or grave occurrence in any area, arising from natural or manmade causes, or by accident or negligence which results in substantial loss of life or human suffering or damage to, and destruction of, property, or damage to, or degradation of, environment, and is of such a nature or magnitude as to be beyond the coping capacity of the community of the affected area.
    • The MHA has defined a disaster as an “extreme disruption of the functioning of a society that causes widespread human, material, or environmental losses that exceed the ability of the affected society to cope with its own resources.

    What is the State Disaster Response Fund?

    • The SDRF is constituted under the Disaster Management Act, 2005 and is the primary fund available with state governments for responses to notified disasters.
    • The Central government contributes 75 per cent towards the SDRF allocation for general category states and UTs, and over 90 per cent for special category states/UTs (which includes northeastern states, Sikkim, Himachal Pradesh and Uttarakhand).
    • For SDRF, the Centre releases funds in two equal instalments as per the recommendation of the Finance Commission.
    • The disasters covered under the SDRF include cyclones, droughts, tsunamis, hailstorms, landslides, avalanches and pest attacks among others.

    The NDRF

    The National Disaster Response Fund, which is also constituted under the Disaster Management Act, 2005 supplements the SDRF of a state, in case of a disaster of severe nature, provided adequate funds are not available in the SDRF.

    Categories of disaster

    • A High Power Committee on Disaster Management was constituted in 1999 to identify disaster categories.
    • It identified 31 disaster categories organised into five major subgroups, which are: water and climate-related disasters, geological related disasters, chemical, industrial and nuclear-related disasters and biological related disasters, which includes biological disasters and epidemics.

    Have there been such instances in the past?

    • In 2018, in view of the devastation caused by the Kerala floods, political leaders in Kerala demanded that the floods be declared a “national calamity”.
    • As of now, there is no executive or legal provision to declare a national calamity.
    • In 2001, the National Committee on Disaster Management under then PM was mandated to look into the parameters that should define a national calamity.
    • However, the committee did not suggest any fixed criterion.
    • In the past, there have been demands from states to declare certain events as natural disasters, such as the Uttarakhand flood in 2013, Cyclone Hudhud in Andhra Pradesh in 2014, and the Assam floods of 2015.

  • Earth’s spin has slowed over time

     

    Earth spun 372 times a year 70 million years ago, compared to the current 365. This means the day was 23½ hours long, compared to 24 today.

    Faster Earth in the olden days

    • It has long been known that Earth’s spin has slowed over time.
    • Previous climate reconstructions, however, have described long-term changes over tens of thousands of years.
    • The new study looked at daily and annual variations in the mollusc shell.

    About the Mollusc

    • A mollusc is an invertebrate of a large phylum which includes snails, slugs, mussels, and octopuses. They have a soft unsegmented body and live in aquatic or damp habitats, and most kinds have an external calcareous shell.
    • The ancient mollusc, Torreites Sanchez, belonged to an extinct group called rudist clams.
    • At 70 million years ago, it belonged to the Late Cretaceous — it was around the time this epoch ended, some 65 million years ago, that dinosaurs went extinct.

    How did researchers conclude this variation?

    • Torreites sanchezi grew very fast, laying down daily growth rings.
    • Using lasers on a single individual, scientists sampled tiny slices and counted the growth rings accurately.
    • This allowed them to determine the number of days in a year 70 million years ago, and more accurately calculate the length of a day.

    Significance of the research

    • It is important to note that the period of Earth’s orbit has remained the same. In other words, one year 70 million years ago was as long as one year today.
    • However, if there were a calendar then, the year would have been 372 “days” long, with each “day” half-an-hour shorter than one day today.
    • Today, Earth’s orbit is not exactly 365 days, but 365 days and a fraction, which is why our calendars have leap years, as a correction.

    The Moon’s retreat

    • Friction from ocean tides, caused by the Moon’s gravity, slows Earth’s rotation and leads to longer days.
    • And as Earth’s spin slows the Moon moves farther away at 3.82 cm per year.
    • If this rate is projected back in time, however, the Moon would be inside the Earth only 1.4 billion years ago.
    • This new measurement, in turn, informs models of how the Moon formed and how closes it has been to Earth over their 4.5-billion-year gravitational relationship.

  • [pib] Effects of Himalayan slip on its Hydrology

    Researchers from the Indian Institute of Geomagnetism have found the mighty Himalayas subside and move up depending on the seasonal changes in groundwater.

    Tectonic activity and groundwater

    • The Himalayan foothills and the Indo-Gangetic plain are sinking because its contiguous areas are rising due to tectonic activity associated with landmass movement or continental drift.
    • The new study shows that subsidence and uplift are found to be associated with seasonal changes in groundwater, apart from the normal, common reasons.
    • Water acts as a lubricating agent, and hence when there is water in the dry season, the rate of the slip of the fault in this region is reduced.
    • In the Himalaya, seasonal water from glaciers, as well as monsoon precipitation, plays a key role in the deformation of the crust and the seismicity associated with it.
    • The subsidence rate is associated with groundwater consumption.

    Findings of the study

    • The researchers have made the combined use of GPS and Gravity Recovery And Climate Experiment (GRACE) data, which has made it possible for them to quantify the variations of hydrologic mass.
    • The GRACE satellites, launched by the US in 2002, monitor changes in water and snow stores on the continents.
    • The combined data suggest a 12% reduction in the rate of the subsurface slip. This slip refers to how fast the fault is slipping relative to the foot and hanging wall.
    • The slip occurs at the Main Himalayan Thrust (MHT), due to hydrological variations and human activities, over which there is the periodic release of accumulated strain.

    About GRACE Mission

    • The Gravity Recovery and Climate Experiment (GRACE) was a joint mission of NASA and the German Aerospace Center.
    • Twin satellites took detailed measurements of Earth’s gravity field anomalies from its launch in March 2002 to the end of its science mission in October 2017.
    • By measuring gravity anomalies, GRACE showed how mass is distributed around the planet and how it varies over time.

     

  • New environment impact norm cuts time for public hearing

    A set of key updates to India’s Environment Impact Assessment (EIA) Act has been proposed to reduce the time given to people to air objections.

    Features proposed by the amendment

    • The draft EIA notification proposes to be an update to the EIA of 2006, which specifies a “minimum of 30 days” for people to respond.
    • The current version of the update, which will likely become law in 60 days, gives a “minimum of 20 days” of notice period.
    • The public hearing process is considered a key component of the EIA. An organisation has to submit a detailed plan, as part of the EIA process that details the nature, need, potential impact and remedial measures, if their proposed infrastructure project threatens to significantly impact a region.
    • It also requires that the public-hearing process be wrapped up in 40 days, as opposed to the existing norm of 45 days.

    Environmental Impact Assessment (EIA) in India

    • EIA is a management tool to minimize adverse impacts of developmental projects on the environment and to achieve sustainable development through timely, adequate, corrective and protective mitigation measures.
    • The MoEFCC uses EIA Notification 2006 as a major tool for minimizing the adverse impact of rapid industrialization on the environment and for reversing those trends which may lead to climate change in long run.
    • EIA has now been made mandatory under the Environmental (Protection Act, 1986 for 29 categories of developmental activities involving investments of Rs. 50 crores and above.

    EIA stages

    1. Screening: This stage decides which projects a full or partial assessment need study.
    2. Scoping: This stage decides which impacts are necessary to be assessed. This is done based on legal requirements, international conventions, expert knowledge and public engagement. This stage also finds out alternate solutions that avoid or at least reduce the adverse impacts of the project.
    3. Assessment & evaluation of impacts and development of alternatives: This stage predicts and identifies the environmental impacts of the proposed project and also elaborates on the alternatives.
    4. EIA Report: In this reporting stage, an environmental management plan (EMP) and also a non-technical summary of the project’s impact is prepared for the general public. This report is also called the Environmental Impact Statement (EIS).
    5. Decision making: The decision on whether the project is to be given approval or not and if it is to be given, under what conditions.
    6. Monitoring, compliance, enforcement and environmental auditing: This stage monitors whether the predicted impacts and the mitigation efforts happen as per the EMP.

    Scope of Environmental Clearance (EC)

    • Environmental clearance is required in respect of all new projects or activities listed in the Schedule to the 2006 notification and their expansion and modernization, including any change in product –mix.
    • Since EIA 2006 the various developmental projects have been re-categorised into category ‘A’ and category ‘B’ depending on their threshold capacity and likely pollution potential.
    • They require prior EC respectively from MOEFCC or the concerned State Environmental Impact Assessment Authorities (SEIAAs).
    • Where state level authorities have not been constituted, the clearance would be provided by the MOEFCC.
