  • Peatlands and their importance

    Sustainably managing peatlands — peat-swamp forests found around the tropics — can protect humans from future pandemics, according to a new study.

    What are Peatlands?

    • Peatlands are terrestrial wetland ecosystems in which waterlogged conditions prevent plant material from fully decomposing.
    • Consequently, the production of organic matter exceeds its decomposition, which results in a net accumulation of peat.
    • Over millennia this material builds up and becomes several metres thick.
    • They occur in almost every country on Earth, currently covering 3% of the global land surface.
    • Peatland landscapes are varied – from blanket bog landscapes with open, treeless vegetation in the Flow Country of Scotland – a tentative World Heritage site – to swamp forests in Southeast Asia.

    Their importance

    • Peatlands are the largest natural terrestrial carbon store. This area sequesters 0.37 gigatonnes of CO2 a year.
    • In their natural, wet state peatlands provide vital ecosystem services.
    • By regulating water flows, they help minimise 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.

    Try this PYQ now:

    In the context of mitigating the impending global warming due to anthropogenic emission of carbon dioxide, which of the following can be the potential sites for carbon sequestration?

    1. Abandoned and Uneconomic coal seams
    2. Depleted oil and gas reservoirs
    3. Subterranean deep saline formations

    Select the correct answer using the code given below:

    (a) 1 and 2 only

    (b) 1 and 3 only

    (c) 3 only

    (d) 1, 2 and 3

    Why conserve peatlands?

    • The protection and restoration of peatlands are vital in the transition towards a low-carbon and circular economy.
    • 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 annually.
    • This is equivalent to 5.6% of global anthropogenic CO2 emissions.
    • Draining peatlands reduces the quality of drinking water due to pollution from dissolved compounds.

    What is the new study?

    • Peatlands were rich in biodiversity, including many potential vertebrate and invertebrate vectors, or carriers of disease, the study said.
    • These included numerous vertebrates known to represent a risk of spreading zoonotic diseases, such as bats, rodents, pangolins and primates.
    • These areas also faced high levels of habitat disruption such as wild or human-made fires and wildlife harvesting that was perfect conditions for potential emerging zoonotic diseases.
    • The first reported case of Ebola in 1976 was from a peatland area.
    • The cradle of the HIV/AIDS pandemic was believed to be around Kinshasa in the Democratic Republic of the Congo, another area with extensive peatlands.

  • Desalination Plants and their Feasibility

    Maharashtra state govt. has announced the setting up of a desalination plant in Mumbai, becoming the fourth state in the country to experiment with the idea.

    Try this PYQ:

    Q.What is the role of ultraviolet (UV) radiation in the water purification systems?

    1. It inactivates/kills the harmful microorganisms in water.
    2. It removes the entire undesirable odour from the water.
    3. It quickens the sedimentation of solid particles, removes turbidity and improves the clarity of water.

    Which of the statements given above is/are correct?

    (a) 1 only

    (b) 2 and 3 only

    (c) 1 and 3 only

    (d) 1, 2 and 3

    What are Desalination Plants?

    • A desalination plant turns salt water into water that is fit to drink.
    • The most commonly used techniques used for the process is reverse osmosis where external pressure is applied to push solvents from an area of high-solute concentration to an area of low-solute concentration through a membrane.
    • The microscopic pores in the membranes allow water molecules through but leave salt and most other impurities behind, releasing clean water from the other side.
    • These plants are mostly set up in areas that have access to seawater.

    How widely is this technology used in India?

    • Desalination has largely been limited to affluent countries in the Middle East and has recently started making inroads in parts of the United States and Australia.
    • In India, Tamil Nadu has been the pioneer in using this technology, setting up two desalination plants near Chennai in 2010 and then 2013, while there are two more to come.

    Need for such plant

    • According to the projections, the population of Mumbai is anticipated to touch 1.72 crores by 2041 and accordingly, the projected water demand would be 6424 MLD by then.
    • Currently, BMC supplies 3850 MLD as against the requirement of 4200 MLD each day.

    Is it ecologically safe?

    • The high cost of setting up and running a desalination plant is one reason why the Maharashtra government has over the last decade been hesitant in building such a plant.
    • Desalination is an expensive way of generating drinking water as it requires a high amount of energy.
    • The other problem is the disposal of the byproduct — highly concentrated brine (saltwater) — of the desalination process.
    • While in most places brine is pumped back into the sea, there have been rising complaints that it ends up severely damaging the local ecology around the plant.

    Back2Basics: Osmosis and Reverse Osmosis

    • Osmosis is a phenomenon where pure water flows from a dilute solution through a semi-permeable membrane to a higher concentrated solution.
    • Semi-permeable means that the membrane will allow small molecules and ions to pass through it but acts as a barrier to larger molecules or dissolved substances.
    • As water passes through the membrane to the salt solution, the level of liquid in the saltwater compartment will rise until enough pressure, caused by the difference in levels between the two compartments, is generated to stop the osmosis.
    • This pressure, equivalent to a force that the osmosis seems to exert in trying to equalize concentrations on both sides of the membrane, is called osmotic pressure.
    • If pressure greater than the osmotic pressure is applied to the high concentration the direction of water flow through the membrane can be reversed.
    • This is called reverse osmosis. Note that this reversed flow produces pure water from the salt solution since the membrane is not permeable to salt.

  • What are Miyawaki Forests?

    Japan-inspired Miyawaki forests are emerging as a popular solution to restoring degraded habitats in the country.

    Try this question:

    Q.The Miyawaki Forests technique has to potential to revolutionize the concept of urban afforestation in India. Discuss.

    Miyawaki Forests

    • Doctor Akira Miyawaki, botanist and professor, is the inventor of the technique since 1980.
    • He is a recipient of the 2006 Blue Planet Prize, which is the equivalent of a Nobel Prize in ecology.
    • The approach is supposed to ensure that plant growth is 10 times faster and the resulting plantation is 30 times denser than usual.
    • It involves planting dozens of native species in the same area and becomes maintenance-free after the first three years.

    The technique

    • The method takes its inspiration directly from processes and diversity in nature: 15 to 30 different species of trees and shrubs are planted together.
    • This plant community works very well together and is perfectly adapted to local weather conditions.
    • The habitat thus created will get more complex over time and attract much biodiversity.
    • Vegetation becomes much denser than conventional plantations, and it has the structure of a mature natural forest. It is a multi-storey structure, where different levels of vegetation appear.
    • The forest thus structured delivers many benefits in the form of ecosystem services.
    • It would take about 200 years to let a forest recover on its own. With the Miyawaki method, a similar result is achieved in 20 years.

  • Chinese dam projects on Brahmaputra and impact on downstream countries

    Scarcity of water in India and China

    • As India and China continue to grow demographically as well as economically amid increased consumption among its citizenry, both nations face water constraints.
    • China, which is home to close to 20 per cent of the world’s population, has only 7 per cent of its water resources.
    • Severe pollution of its surface and groundwater caused by rapid industrialisation is a source of concern for Chinese planners.
    • China’s southern regions are water-rich in comparison to the water-stressed northern part.
    • The southern region is a major food producer and has significant industrial capacity as a consequence of more people living there.
    • India is severely water-stressed as well.
    • Similar to China, India has 17 per cent of the world’s population and 4 per cent of water.
    • As in China, an equally ambitious north-south river-linking project has been proposed in India.

    Impact on downstream states

    • The construction of several dams along the Yarlung (Brahmaputra) river on the Chinese side has been a repeated cause for concern for Indian officials and the local people.
    • China has an ambitious plan to link its south and north through canals, aqueducts and linking of major rivers to ensure water security.
    • In pursuit of these goals, China, being an upper riparian state in Asia, has been blocking rivers like the Mekong and its tributaries, affecting Southeast Asian countries like Thailand, Vietnam, Laos and Cambodia.
    • It has caused immense damage to the environment and altered river flows in the region.
    • China sees these projects as a continuation of their historic tributary system as the smaller states have no means of effectively resisting or even significant leverage in negotiations.

    Challenges for India

    • There are now multiple operational dams in the Yarlung Tsangpo basin with more dams commissioned and under construction. These constructions present a unique challenge for Indian planners.
    • 1) Dams will eventually lead to degradation of the entire basin:
    • Silt carried by the river would get blocked by dams leading to a fall in the quality of soil and eventual reduction in agricultural productivity.
    • 2) The Brahmaputra basin is one of the world’s most ecologically sensitive zones.
    • It is identified as one of the world’s 34 biological hotspots.
    • This region sees several species of flora and fauna that are endemic to only this part of the world.
    • The river itself is home to the Gangetic river dolphin, which is listed as critically endangered.
    • 3) The location of the dams in the Himalayas pose a risk.
    • Seismologists consider the Himalayas as most vulnerable to earthquakes and seismic activity.
    • The sheer size of the infrastructure projects undertaken by China, and increasingly by India, poses a significant threat to the populations living downstream.
    • Close to a million people live in the Brahmaputra basin in India and tens of millions further downstream in Bangladesh.
    • 4) Damming Brahmaputra would result in water security in an era of unprecedented shifting climate patterns.
    • This security extends beyond water, as there is the potential to significantly change the flow rate during times of standoffs and high tensions.

    Way forward

    • Both sides must cease new constructions on the river and commit to potentially less destructive solutions.
    • Building a decentralised network of check dams, rain-capturing lakes and using traditional means of water capture have shown effective results in restoring the ecological balance while supporting the populations of the regions in a sustainable manner.

    Conclusion

    There are alternate solutions to solving the water crisis.  It is in the interest of all stakeholders to neutralise this ticking water bomb.

  • India’s Deep Ocean Mission

    India will soon launch an ambitious ‘Deep Ocean Mission’ that envisages exploration of minerals, energy and marine diversity of the underwater world, a vast part of which still remains unexplored.

    Deep Ocean Mission (DOM)

    Nodal Agency: Ministry of Earth Sciences (MoES)

    • The mission proposes to explore the deep ocean similar to the space exploration started by ISRO.
    • Underwater robotics and ‘manned’ submersibles are key components of the Mission which will help India harness various living and non-living (water, mineral and energy) resources from the seabed and deep water.
    • The tasks that will be undertaken over this period include deep-sea mining, survey, energy exploration and the offshore-based desalination.
    • These technological developments are funded under an umbrella scheme of the government – called Ocean Services, Technology, Observations, Resources Modelling and Science (O-SMART).

     Mining PMN

    • One of the main aims of the mission is to explore and extract polymetallic nodules (PMN).
    • These are small potato-like rounded accretions composed of minerals such as manganese, nickel, cobalt, copper and iron hydroxide.
    • They lie scattered on the Indian Ocean floor at depths of about 6,000 m and the size can vary from a few millimetres to centimetres.
    • These metals can be extracted and used in electronic devices, smartphones, batteries and even for solar panels.

    Where will the team mine?

    • The International Seabed Authority (ISA), an autonomous international organisation established under the 1982 United Nations Convention on the Law of the Sea, allots the ‘area’ for deep-sea mining.
    • India was the first country to receive the status of a ‘Pioneer Investor ‘ in 1987 and was given an area of about 1.5 lakh sq km in the Central Indian Ocean Basin (CIOB) for nodule exploration.
    • In 2002, India signed a contract with the ISA and after complete resource analysis of the seabed 50% was surrendered and the country retained an area of 75,000 sq km.

    Which are the other countries that are in the race to mine the deep sea?

    • Apart from the CIOB, polymetallic nodules have been identified from the central Pacific Ocean. It is known as the Clarion-Clipperton Zone.
    • According to the ISA’s website, it has entered into 15-year contracts for exploration for polymetallic nodules, polymetallic sulphides and cobalt-rich ferromanganese crusts in the deep seabed with 29 contractors.
    • Later it was extended for five more years till 2022.
    • China, France, Germany, Japan, South Korea, Russia and also some small islands such as the Cook Islands, Kiribati have joined the race for deep-sea mining.
    • Most of the countries have tested their technologies in shallow waters and are yet to start deep-sea extraction.

    India’s preparedness

    • India’s mining site is at about a depth of 5,500 metres, where there is a high pressure and extremely low temperature.
    • We have also deployed Remotely Operated Vehicle and In-situ Soil Tester in the depth of 6,000 metres and have a thorough understanding of the mining area at the Central Indian Ocean Basin.
    • The mining machine newly developed for 6000 metres depth was able to move about 900 metres and will be deployed soon at 5,500 metres.
    • Weather conditions and the availability of ships also play a role.
    • More tests are being conducted to understand how to bring the nodules up to the surface. A riser system comprising an umbilical cable or electromechanical cable and a hose is being developed.

    What will be the environmental impact?

    • According to the IUCN, these deep remote locations can be home to unique species that have adapted themselves to conditions such as poor oxygen and sunlight, high pressure and extremely low temperatures.
    • Such mining expeditions can make them go extinct even before they are known to science.
    • The deep sea’s biodiversity and ecology remain poorly understood, making it difficult to assess the environmental impact and frame adequate guidelines.
    • Though strict guidelines have been framed, they are only exploration guidelines. A new set of exploitation guidelines are being worked out and discussions are on with the ISA.
    • Environmentalists are also worried about the sediment plumes that will be generated as the suspended particles can rise to the surface harming the filter feeders in the upper ocean layers.
    • Additional concerns have been raised about the noise and light pollution from the mining vehicles and oil spills from the operating vessels.

    Is deep-sea mining economically viable?

    • The latest estimate from the ISA says it will be commercially viable only if about three million tonnes are mined per year.
    • More studies are being carried out to understand how the technology can be scaled up and used efficiently.

  • Species in news: Meghalaya’s Glowing Mushrooms

    A mushroom documentation project in the forests of Northeast India has discovered a bioluminescent — or light-emitting — variety of mushroom.

    Try this PYQ:

    Q.Lichens, which are capable of initiating ecological succession even on a bare rock, are actually a symbiotic association of:

    (a) Algae and bacteria

    (b) Algae and fungi

    (c) Bacteria and fungi

    (d) Fungi and mosses

    Roridomyces phyllostachydis

    • The new species was first sighted near a stream in Meghalaya’s Mawlynnong in East Khasi Hills district and later at Krang Shuri in West Jaintia Hills district.
    • It is now one among the 97 known species of bioluminescent fungi in the world.

    Bioluminescence in fungi

    • Bioluminescence is the property of a living organism to produce and emit light.
    • Bioluminescent organisms are usually found in ocean environments, but they are also found in terrestrial environments.
    • The colour of the light emitted by the organism depends on its chemical properties.
    • In the case of fungi, the luminescence comes from the enzyme, luciferase.
    • The green light emits when luciferans is catalysed by the enzyme luciferase, in the presence of oxygen.

  • [pib] India’s first Green Energy Convergence Project

    The Energy Efficiency Services Limited (EESL) is set to roll out of India’s first Energy Convergence Project in Goa.

    Green Energy Convergence Project

    • Under the project, EESL and the Department of New and Renewable Energy (DNRE) in Goa will carry out feasibility studies and implementation of decentralized solar energy projects.
    • The project aims to connect seemingly independent sectors like Solar Energy, Energy Storage and LED lights to provide solutions, which can enable in decarbonisation and affordable energy access.
    • It will include the installation of 100 Megawatt decentralized ground-mounted solar power projects on government land to be used for agricultural pumping.
    • It seeks to replace 6,300 agricultural pumps and distribute 16 lakh LED bulbs for rural domestic households.

    Benefits of the project

    • The projects will accelerate the usage of renewable energy sources, especially for agricultural and rural power consumption in the State.
    • They will also contribute to the reduction of peak energy demand through the deployment of energy-efficient pumping and lighting thus contributing to overall sustainability.

    About EESL

    • A joint venture of NTPC Limited, Power Finance Corporation, Rural Electrification Corporation and POWERGRID, the EESL was set up under Ministry of Power to facilitate the implementation of energy efficiency projects.
    • EESL is a Super Energy Service Company (ESCO) that seeks to unlock energy efficiency market in India, that can potentially result in energy savings of up to 20 per cent of current consumption.
    • It also acts as the resource centre for capacity building of State DISCOMs, ERCs, SDAs, upcoming ESCOs, financial institutions, etc.

  • India’s challenge in balancing the emissions and economy

    India faces an uphill task of balancing its climate action with the economic growth. Bridging the energy deficit through renewable energy in cost-effective and increasing urban forestry could help in balancing the both.

    Comparing India’s commitment

    • China’s announcement recently to achieve carbon neutrality, that is, effectively generating net-zero emissions, before 2060 has now shifted focus on India’s commitments.
    • In this context,  let us compare India’s commitments with other countries, based on an independent scientific analysis carried out by the Climate Action Tracker. Major findings of it are:-
    • 1) India is one of the only six countries (amongst the 33 that were assessed), and the only G-20 country, whose climate commitments at Paris are on a path compatible to limit warming well below 2°C.
    • 2) It seems that India is well on its way to achieving its carbon intensity reduction and non-fossil-fuel electricity growth capacity commitments well before the 2030 target year.
    • Even though China’s commitment is likely to lower warming projections by around 0.2 to 0.3 degrees C by 2100, China continues to remain in the “highly insufficient” category.
    • India, despite being the fourth-largest emitter, has consistently kept its commitments in sync with its fair share and will achieve, if not over-achieve, these targets.

    Difference in development and growth levels

    • Development and growth in India are still at an early stage, and our first goal remains increasing the availability of adequate infrastructure for all Indians.
    • A measure of this deficit is that we use only about 0.6 tonnes of oil-equivalent worth of energy per person per year while in China it is 2.36 tonnes per person per year, and is at least 4 tonnes per person per year in the OECD countries.
    • It is, therefore, essential that we rapidly bridge the energy deficit.

    Bridging the energy deficit through renewable and cost-effective manner

    • Cost-effectiveness in renewable electricity has occurred rather rapidly, largely as a result of the global reduction in solar PV and battery prices.
    • Solar electricity is already the cheapest electricity available in India when the sun is shining.
    • It now seems that round-the-clock renewable electricity may be cost-competitive with coal electricity in the near future.
    • This cost-effectiveness of zero-carbon options will emerge in other applications as well.
    • It will involve dedicated action in some of the vital sectors which can generate and sustain employment while adding to the country’s economic growth.
    • It will enable a shift away from emissions-intensive fossil fuels, reducing our dependence on fuel imports.

    Urban forestry to compensate for environmental degradation

    • Increasing urban forestry could help compensate for environmental degradation as a result of rapid urbanisation in several Indian cities.
    • This is vital to restore the flow of crucial ecosystem services, including air quality, and increase the resilience of cities to extreme climatic events.
    • As a result, enhancing biodiversity, minimising human-wildlife conflict and restoring India’s pristine forests by developing dedicated wildlife/biodiversity corridors is an essential next step.

    Way ahead

    • At the developmental crossroads that India stands, the next decade is vital for its own economic growth, its climate action, and its social and ecological well-being.
    • With this in mind, India must focus on its domestic developmental prerogative and disengage them from the pressures that come along with international negotiations, focussing on actions that reduce the development deficits, which also provide strong climate benefits.
    • India must initiate a narrative, discussion and dialogue which focuses on each country taking on commitments that move their carbon trajectory towards the Paris agreement goal of limiting global warming to well below 2°C.

    Consider the question “Development and growth in India still at an early stage which makes the challenge of balancing the commitment to climate action with economic developement more difficult. In light of this, suggest the strategy that India should follow.”

    Conclusion

    India, being at the crossroads of development needs to balance the development goals with its commitment towards climate action.

  • Vulture Action Plan for 2020-25

    Union Minister for Environment, Forests and Climate Change has launched a Vulture Action Plan 2020-25 for the conservation of vultures in the country.

    Vulture Action Plan

    • While the ministry has been carrying out a conservation project for vultures since 2006, the plan is to now extend the project to 2025 to not just halt the decline but to actively increase the vulture numbers in India.
    • There are nine recorded species of vultures in India — the Oriental white-backed, long-billed, slender-billed, Himalayan, red-headed, Egyptian, bearded, cinereous and the Eurasian Griffon.
    • Vulture numbers saw a steep slide — as much as 90 per cent in some species — in India since the 1990s in one of the most drastic declines in bird populations in the world.

    Decline in Populations

    • Between the 1990s and 2007, numbers of three presently critically-endangered species – the Oriental white-backed, long-billed and slender-billed vultures — crashed massively with 99 per cent of the species having been wiped out.
    • The number of red-headed vultures, also critically-endangered now, declined by 91% while the Egyptian vultures by 80%.
    • The Egyptian vulture is listed as ‘endangered’ while the Himalayan, bearded and cinereous vultures are ‘near threatened’.

    Why protect vultures?

    • Vultures are often overlooked and perceived as lowly scavengers, but they play a crucial role in the environments in which they live.
    • The scavenging lifestyle that gives them a bad reputation is, in fact, that makes them so important for the environment, nature and society.
    • Vultures, also known as nature’s cleanup crew, do the dirty work of cleaning up after death, helping to keep ecosystems healthy as they act as natural carcass recyclers.

    Various threats

    • The crash in vulture populations came into limelight in the mid-90s, and in 2004.
    • The cause of the crash was established as diclofenac — a veterinary nonsteroidal anti-inflammatory drug (NSAID) used to treat pain and inflammatory diseases such as gout — in carcasses that vultures would feed off.
    • Just 0.4-0.7 per cent of animal carcasses contaminated with diclofenac was sufficient to decimate 99 per cent of vulture populations.

    Various initiatives

    • The MoEFCC released the Action Plan for Vulture Conservation 2006 with the drugs controller banning the veterinary use of diclofenac in the same year and the decline of the vulture population being arrested by 2011.
    • The Central Zoo Authority (CZA) and Bombay Natural History Society (BNHS) also established the Vulture Conservation Breeding Programme.
    • It has been successful and had three critically-endangered species bred in captivity for the first time.
    • The ministry has now also launched conservation plans for the red-headed and Egyptian vultures, with breeding programmes for both.
    • The Vulture Safe Zone programme is being implemented at eight different places in the country where there were extant populations of vultures, including two in Uttar Pradesh.

  • Lonar Lake, Sur Sarovar declared as Ramsar sites

    The Lonar Lake in Maharashtra and Sur Sarovar, also known as Keetham lake, in Agra, have been added to the list of recognised Ramsar sites.

    Make a note of all freshwater and saltwater lakes in India.

    Lonar Lake

    • Lonar Lake, also known as Lonar crater, is a notified National Geo-heritage Monument, saline (pH of 10.5), Soda Lake, located at Lonar in Buldhana district, Maharashtra.
    • It was created by an asteroid collision with earth impact during the Pleistocene Epoch.
    • It is one of the four known, hyper-velocity, impact craters in basaltic rock anywhere on Earth.
    • It sits inside the Deccan Plateau—a massive plain of volcanic basalt rock created by eruptions some 65 million years ago.

    Sur Sarovar

    • It is a scenic lake just outside Agra on the Agra – Delhi highway (NH 2) and a declared bird sanctuary.
    • The riverine belt of River Yamuna surrounds the area of Sur-Sarovar.
    • It is today home to more than 165 species of migratory and resident birds.
    • It is the same place that inspired the famed poet Soordas to compose the “Bhakti Kavya” one of the finest pieces of devotional poetry.

    Two amongst many

    • India now has 41 wetlands, the highest in South Asia, with two more added to the list of recognised sites of international importance under the treaty of Ramsar Convention.
    • Recently, Kabartal in Bihar’s Begusarai district was recognised as a wetland of international importance, the first such wetland in the State, under the Ramsar Convention.
    • The Asan Conservation Reserve in Dehradun, the first wetland from Uttarakhand to be recognised by Ramsar convention, was added to the list in October this year.

    Back2Basics: Wetlands

    • A wetland is a distinct ecosystem that is flooded by water, either permanently or seasonally, where oxygen-free processes prevail.
    • The primary factor that distinguishes wetlands from other landforms or water bodies is the characteristic vegetation of aquatic plants, adapted to the unique hydric soil.
    • Wetlands provide a wide range of important resources and ecosystem services such as food, water, fibre, groundwater recharge, water purification, flood moderation, erosion control and climate regulation.

    What is the Ramsar Convention?

    • The Ramsar Convention on Wetlands of International Importance Especially as Waterfowl Habitat is a treaty for the conservation and sustainable use of such sites.
    • The convention, signed in 1971 in the Iranian city of Ramsar, is one of the oldest inter-governmental accords for preserving the ecological character of wetlands.
    • Also known as the Convention on Wetlands, it aims to develop a global network of wetlands for the conservation of biological diversity and for sustaining human life.
    • Over 170 countries are party to the Ramsar Convention and over 2,000 designated sites covering over 20 crore hectares have been recognised under it.
