  • NGT upholds rights of pastoralists in Banni Grasslands

    The National Green Tribunal (NGT) ordered all encroachments to be removed from Gujarat’s Banni grasslands.

    Banni Grasslands

    • Banni Grasslands form a belt of arid grassland ecosystem on the outer southern edge of the desert of the marshy salt flats of Rann of Kutch.
    • They are known for rich wildlife and biodiversity and are spread across an area of 3,847 square kilometers. Two ecosystems, wetlands and grasslands, are juxtaposed in Banni.
    • They are currently legally protected under the status as a protected or reserve forest in India.
    • Wildlife Institute of India (WII) has identified this grassland reserve as one of the last remaining habitats of the cheetah in India and a possible reintroduction site for the species.
    • The region hosts a nomadic pastoralist community, the Maldharis, whose livelihoods depend on this protected shrub-savanna.

    Answer this PYQ in the comment box:

    Q.Which one of the following is the correct sequence of ecosystems in the order of decreasing productivity?(CSP 2014)

    (a) Oceans, lakes, grasslands, mangroves

    (b) Mangroves, oceans, grasslands, lakes

    (c) Mangroves, grasslands, lakes, oceans

    (d) Oceans, mangroves, lakes, grasslands

    What is the recent NGT verdict?

    • The court also said the Maldharis will continue to hold the right to conserve the community forests in the area, granted to them as per the provisions in Section 3 of Forest Rights Act, 2006.
    • NGT highlighted that the lack of coordination between the forest department and the revenue department lead to the problem of encroachment.
    • The grassland was first declared a “protected forest” in May 1955, using the nomenclature of the Indian Forest Act, 1927.
    • Since then, the actual transfer of the land from the Revenue department to the Forest department has not been completed.

    Back2Basics: National Green Tribunal

    • The NGT has been established in 2010 under the National Green Tribunal Act 2010.
    • It works for:
    1. effective and expeditious disposal of cases relating to environmental protection
    2. conservation of forests and other natural resources including enforcement of any legal right relating to environment and
    3. giving relief and compensation for damages to persons and property and for matters connected therewith or incidental thereto
    • It is not be bound by the procedure laid down under the Code of Civil Procedure, 1908, but shall be guided by principles of natural justice.
    • The Tribunal’s dedicated jurisdiction in environmental matters shall provide speedy environmental justice and help reduce the burden of litigation in the higher courts.
    • The Tribunal is mandated to make and endeavour for disposal of applications or appeals finally within 6 months of filing of the same.
    • Initially, the NGT is proposed to be set up at five places of sittings and will follow circuit procedure for making itself more accessible.
    • New Delhi is the Principal Place of Sitting of the Tribunal and Bhopal, Pune, Kolkata and Chennai shall be the other four place of sitting of the Tribunal.

  • What is a Supermoon?

    The Moon will have the nearest approach to Earth on May 26, and therefore will appear to be the closest and largest Full Moon or “supermoon” of 2021.

    Tap here to read more about Solar and Lunar Eclipses

    What is a Supermoon?

    • A supermoon occurs when the Moon’s orbit is closest to the Earth at the same time that the Moon is full.
    • As the Moon orbits the Earth, there is a point of time when the distance between the two is the least (called the perigee when the average distance is about 360,000 km from the Earth).
    • Also, there is a point of time when the distance is the most (called the apogee when the distance is about 405,000 km from the Earth).
    • Now, when a full moon appears at the point when the distance between the Earth and the Moon is the least, not only does it appear to be brighter but it is also larger than a regular full moon.
    • According to NASA, the term supermoon was coined by astrologer Richard Nolle in 1979.
    • In a typical year, there may be two to four full supermoons and two to four new supermoons in a row.

    What is happening today?

    • Two celestial events will take place at the same time.
    • One is the supermoon and the other is a total lunar eclipse, which is when the Moon and Sun are on opposite sides of the Earth.
    • Because of the total lunar eclipse, the moon will also appear to be red.
    • This is because the Earth will block some of the light from the Sun from reaching the moon.
    • The Earth’s atmosphere filters the light, it will soften “the edge of our planet’s shadow” “giving the Moon a deep, rosy glow.”

  • [pib] Recycling Carbon Technology

    A Bangalore-based startup has received the National Award 2021 for developing efficient catalysts and methodologies for the conversion of CO2 to methanol and other chemicals.

    Carbon Recycling

    • It has led to the improvisation of process engineering to enhance the production of chemicals and fuels from anthropogenic CO2.
    • It has integrated multiple components involved in the CCUS (Carbon capture, utilization, and sequestration) to develop a complete solution for the environmental issues due to global warming.
    • The current capacity of CO2 conversion is 300 kg per day, which can be scaled up to several 100 tons on an industrial scale.

    What is CCUS?

    • Carbon Capture, Utilization, and Storage (CCUS) encompass methods and technologies to remove CO2 from the flue gas and from the atmosphere.
    • CCUS involves multiple aspects that need to be in sync for the successful removal or capture of CO2 from the flue gas or the atmosphere, followed by utilization and storage.
    • Carbon capture involves the development of sorbents that can effectively bind to the CO2 present in flue gas or the atmosphere, which is expensive.
    • In addition, there has been a considerable debate about the fate of captured and compressed CO2.

  • Deep Sea Faunal Diversity in India

    India is home to 4,371 species of deep-sea fauna, including 1,032 species under the kingdom Protista and 3,339 species under the kingdom Animalia, a recent publication by the Zoological Survey of India (ZSI) has revealed.

    Highlights of the Survey

    • India is surrounded by the Arabian Sea, the Bay of Bengal, the Andaman Sea, and the Laccadive Sea (Lakshadweep Sea).
    • Of the 4,371 species, a maximum of 2,766 species has been reported from deep-sea areas of the Arabian Sea, followed by 1,964 species from the Bay of Bengal, 1,396 species from the Andaman Sea, and only 253 species from the Laccadive Sea.

    RIMS ship investigator

    • India is one of the countries that made a pioneering exploration in the deep Indian Ocean region in 1874 by commissioning a RIMS (Royal Indian Marine Survey) ship investigator.
    • This conducted enormous studies in seas around India and continued to work till 1926.

    Components of the exploration

    • The deep-sea ecosystem was the most unexplored ecosystem across the world. It included hydrothermal vents, submarine canyons, deep-sea trenches, seamounts, cold seeps, and mud volcanoes.
    • This publication, the first of its kind, provides baseline information on all groups of fauna and biological organisms in the Indian deep seas.
    • Not only will this support our knowledge on conserving and managing deep-sea faunal resources, but it will also pave way for their sustainable utilization.

    Key findings

    (1) Mammals

    • There are 31 species of sea mammals that are found in the deep-sea ecosystem of Indian waters, including the Critically Endangered Irrawaddy Dolphin.
    • Two other species, the Indo-Pacific Finless Porpoise and the Sperm Whale are recorded as ‘Vulnerable’ in the IUCN classification.
    • The list of mammals includes Cuvier’s Beaked Whale and Short-beaked Common Dolphin, which dive as deep as 8,000 meters below the Earth’s surface.

    (2) Marine turtles

    • Out of the seven species of marine turtles found across the world, five species have been recorded from Indian waters.
    • India is known as one of the best and largest breeding grounds for sea turtles, especially for Olive Ridley and Leatherback Turtles, across the world.

  • Eruption of Mount Nyiragongo

    Thousands have fled a volcanic eruption in the Democratic Republic of Congo from Mount Nyiragongo on the outskirts of Goma City.

    These were some volcanoes in news this year:

    Mount Vesuvius, Taal Volcano, La Soufriere

    Mount Nyiragongo

    • Mount Nyiragongo is an active stratovolcano with an elevation of 3,470 m (11,385 ft) in the Virunga Mountains associated with the Albertine Rift.
    • The main crater is about 2km wide and usually contains a lava lake.
    • The crater presently has two distinct cooled lava benches within the crater walls.
    • It is one of the 16 Decade Volcanoes.
    • Nyiragongo’s lava lake has at times been the most voluminous known lava lake in recent history. The depth of the lava lake varies considerably.
    • Nyiragongo and nearby Nyamuragira are together responsible for 40 percent of Africa’s historical volcanic eruptions.

    Q.Which of the following adds/add carbon dioxide to the carbon cycle on the planet Earth?

    1. Volcanic action
    2. Respiration
    3. Photosynthesis
    4. Decay of organic matter

    Select the correct answer using the code given below:

    (a) 1 and 3 only

    (b) 2 only

    (c) 1, 2 and 4 only

    (d) 1, 2, 3 and 4

    What are Decade Volcanoes?

    • The Decade Volcanoes are 16 volcanoes identified by the International Association of Volcanology and Chemistry of the Earth’s Interior (IAVCEI).
    • They are considered worthy of particular study in light of their history of large, destructive eruptions and proximity to densely populated areas.
    • They are named Decade Volcanoes because the project was initiated in the 1990s as part of the United Nations-sponsored International Decade for Natural Disaster Reduction.

  • Benefits of environmental fiscal reforms

    The article highlights the advantages of environmental fiscal reforms in India.

    Status of  out-of-pocket spending on health in India

    • As per WHO data, in 2011,  17.33% of the population in India made out-of-pocket payments on health that was more than 10% of their income.
    • The percentage was higher in rural areas compared to urban areas.
    • Globally, 12.67% of the population spent more than 10% of their income (out of their pocket) on health.
    • In Southeast Asia, 16% spent more than 10% of their household income on health.
    • Similarly, 3.9% of the population in India made more than 25% of out-of-pocket payments on health, with 4.34% of it in the rural areas.

    Alternate source of health financing: Eco tax

    • The Economic Survey of India 2019-20 has outlined that an increase in public spending from 1% to 2.5-3% of GDP, can decrease out-of-pocket expenditure from 65% to 30% of overall healthcare expenses.
    • The National Health Policy of 2017 also envisages increase in public spending from 1% to 2.5-3% of GDP.
    • This is where the importance of alternate sources of health financing in India needs to be stressed.
    • Fiscal reforms for managing the environment are important, and India has great potential for revenue generation in this aspect.

    Environmental tax reforms

    • Environmental tax reforms generally involve three complementary activities:
    • 1. Eliminating existing subsidies and taxes that have a harmful impact on the environment;
    • 2. Restructuring existing taxes in an environmentally supportive manner;
    • 3. Initiating new environmental taxes.
    • Taxes can be designed either as revenue neutral or revenue augmenting.
    • Revenue augmenting model: In case of revenue augmenting, the additional revenue can either be targeted towards the provision of environmental public goods or directed towards the overall revenue pool.
    • In developing countries like India, the revenue can be used to a greater extent for the provision of environmental public goods and addressing environmental health issues.

    Eco tax

    • The success of an eco tax (environment tax) in India would depend on its architecture, that is, how well it is planned and designed.
    • It should be credible, transparent and predictable.
    • Ideally, the eco tax rate ought to be equal to the marginal social cost arising from the negative externalities associated with the production, consumption or disposal of goods and services.
    • This would include the adverse impacts on the health of people, climate change, etc.
    • The eco tax rate may, thus, be fixed commensurate to the marginal social cost so evaluated.
    • There is also a need to integrate environmental taxes in the Goods and Service Tax framework.

    In India, eco taxes can target three main areas

    • One, differential taxation on vehicles in the transport sector purely oriented towards fuel efficiency and GPS-based congestion charges.
    • Two, in the energy sector by taxing fuels which feed into energy generation.
    • Three, waste generation and use of natural resources.

    Benefits of implementation of eco taxes

    • The implementation of an environmental tax in India will have three broad benefits: fiscal, environmental and poverty reduction.
    • Finance basic public services: Environmental tax reforms can mobilise revenues to finance basic public services when raising revenue through other sources proves to be difficult or burdensome.
    • Reduce distorting taxes: It can can also help to reduce other distorting taxes such as fiscal dividend.
    • Finance research: Environmental tax reforms help internalise the externalities, and the said revenue can finance research and the development of new technologies.

    Impact

    • Environmental regulations may lead to slow productivity growth and high cost of compliance in private sector.
    • This could result in the possible increase in the prices of goods and services.
    • However, the European experience shows that most of the taxes also generate substantial revenue and there is no evidence on green taxes with sustainable development goals leading to a ‘no growth’ economy.
    • Negligible impact on GDP: Most countries’ experiences suggest negligible impact on the GDP, though such revenues have not necessarily been used for environmental considerations.
    • The negligible impact on the GDP may be a temporary phenomenon.

    Conclusion

    This is the right time for India to adopt environmental fiscal reforms as they will reduce environmental pollution and also generate resources for financing the health sector.

  • Person in news: Sunderlal Bahuguna

    Veteran environmentalist and architect of the Chipko Movement Sundarlal Bahuguna, 94 has succumbed to COVID.

    Answer this PYQ in the comment box:

    Q.In India, the problem of soil erosion is associated with which of the following?

    1. Terrace cultivation
    2. Deforestation
    3. Tropical climate

    Select the correct answer using the code given below:

    (a) 1 and 2 only

    (b) 2 only

    (c) 1 and 3 only

    (d) 1, 2 and 3

    Sunderlal Bahuguna

    • Bahuguna was one of the leaders of the Chipko movement, fighting for the preservation of forests in the Himalayas.
    • Chipko means ‘embrace’ or ‘tree huggers’ and this vast movement was a decentralized one with many leaders usually being village women.
    • Often, they would chain themselves to trees so that loggers could not cut down forests.
    • These actions slowed down the destruction, but more importantly, they brought deforestation to the public’s attention.

    His contributions

    • From 1981-1983, Sundarlal Bahuguna led a 5,000-kilometre march across the Himalayas, ending with a meeting with late PM Indira Gandhi, to protect some areas of the Himalayan forests from tree-felling.
    • Sundarlal Bahuguna was also a leader in the movement to oppose the Tehri dam project and in defending India’s rivers.
    • He also worked for women’s rights and the rights of the poor.
    • His methods were Gandhian, making use of peaceful resistance and non-violence.
    • The Chipko Movement received the 1987 Right Livelihood Award, also referred to as the Alternative Nobel Prize.

  • World’s largest iceberg breaks off from Antarctica

    A huge ice block has broken off from western Antarctica into the Weddell Sea, becoming the largest iceberg in the world and earning the name A-76.

    Answer this PYQ in the comment box:

    Q.On the planet earth, most of the freshwater exists as ice caps and glaciers. Out of the remaining freshwater, the largest proportion:

    (a) is found in the atmosphere as moisture and clouds

    (b) is found in freshwater lakes and rivers

    (c) exists as groundwater

    (d) exists as soil moisture

    A-76 Iceberg

    • A-76 is the latest in a series of large ice blocks to dislodge in a region acutely vulnerable to climate change, although scientists said in this case it appeared to be part of a natural polar cycle.
    • The iceberg, measuring around 170 km long and 25 km wide, with an area of 4,320 sq km is now floating in the Weddell Sea.
    • Slightly larger than the Spanish island of Majorca, A-76 had been monitored by scientists since it began to separate from the Ronne Ice Shelf.
    • It joins the previous world’s largest title holder A-23A — approximately 3,880 sq. km. in size — which has remained in the same area since 1986.
    • A-76 was originally spotted by the British Antarctic Survey and the calving — the term used when an iceberg breaks off — was confirmed using images from the Copernicus satellite.

    Note: An iceberg is a large piece of freshwater ice that has broken off a glacier or an ice shelf and is floating freely in open water.

  • Places in news: Leang Sakapao Caves

    Researchers have reported that Pleistocene-era rock paintings dating back to 45,000-20,000 years ago in cave sites in southern Sulawesi, on the Indonesian island of Sulawesi, are weathering at an alarming rate.

    Have you ever found the mention of ‘Altamira Caves’ in your NCERTs?

    Leang Sakapao Caves

    • This cave art of Sulawesi is much older than the prehistoric cave art of Europe.
    • The artwork in the area includes what is believed to be the world’s oldest hand stencil (almost 40,000 years ago), created by pressing the hand on a cave wall and spraying wet red-mulberry pigments over it.
    • A nearby cave features the world’s oldest depiction of an animal, a warty pig painted on the wall 45,500 years ago.

    Impact of climate change

    • The artwork made with pigments was decaying due to a process known as haloclasty, which is triggered by the growth of salt crystals due to repeated changes in temperature and humidity.
    • This is caused by alternating wet and dry weather in the region.
    • Indonesia has also experienced several natural disasters in recent years, which have quickened the process of deterioration.

    Note:

    Mark all islands of the Indonesian Archipelago in your Atlas.

  • Cyclone Tauktae

    Cyclone Tauktae (pronounced Tau-Te), classified as a very severe cyclonic storm (VSCS) and developed in the Arabian Sea, is wreaking havoc all across the Indian Coast.

    Don’t you think?

     In recent years, strong cyclones have been developing in the Arabian Sea more frequently than earlier.

    Cyclone Tauktae

    • Tauktae is a currently active and strengthening tropical cyclone threatening the state of Gujarat in India and impacting the states Karnataka, Goa and Maharashtra.
    • It is the fourth cyclone in consecutive years to have developed in the Arabian Sea, that too in the pre-monsoon period (April to June).
    • All these cyclones since 2018 have been categorised as either ‘Severe Cyclone’ or above.
    • Once Tauktae makes its landfall, three of these will have hit either the Gujarat or Maharashtra coast.
    • After Cyclone Mekanu in 2018, which struck Oman, Cyclone Vayu in 2019 struck Gujarat, followed by Cyclone Nisarga in 2020 that struck Maharashtra.

    What is aiding such rapid intensification?

    • Any tropical cyclone requires energy to stay alive.
    • This energy is typically obtained from the warm water and humid air over the tropical ocean.
    • Currently, seawater up to depths of 50 metres has been very warm, supplying ample energy to enable the intensification of Cyclone Tauktae.
    • The more the heat released through condensation of water vapour, the steeper the drop in pressure.
    • A low-pressure system undergoes multiple stages of intensification to form cyclones.

    Not a rare phenomenon

    • Typically, tropical cyclones in the North Indian Ocean region (the Bay of Bengal and the Arabian Sea) develop during the pre-monsoon and post-monsoon (October to December) periods.
    • May-June and October-November are known to produce cyclones of severe intensity that affect the Indian coasts.

    Is the Arabian Sea becoming cyclone-friendly?

    • Annually, five cyclones on average form in the Bay of Bengal and the Arabian Sea combined.
    • Of these, four developments in the Bay of Bengal, which is warmer than the Arabian Sea.
    • In the Arabian Sea, cyclones typically develop over the Lakshadweep area and largely traverse westwards, or away from India’s west coast.
    • However, in recent years, meteorologists have observed that the Arabian Sea, too, has been warming. This is a phenomenon associated with global warming.

    Back2Basics: Tropical Cyclone

    • A tropical cyclone is a rapidly rotating storm system characterized by a low-pressure centre, a closed low-level atmospheric circulation, strong winds, and a spiral arrangement of thunderstorms that produce heavy rains.
    • Depending on its location and strength, a tropical cyclone is referred to by different names, including hurricane, typhoon, tropical storm, cyclonic storm, tropical depression, or simply cyclone.
    • A hurricane is a tropical cyclone that occurs in the Atlantic Ocean and the northeastern Pacific Ocean, and a typhoon occurs in the northwestern Pacific Ocean.
    • In the south Pacific or the Indian Ocean, comparable storms are referred to simply as “tropical cyclones” or “severe cyclonic storms”.
