  • Voluntary Disclosure of Exotic Pets

    Last month, the Supreme Court upheld an Allahabad High Court order granting immunity from investigation and prosecution if one declared illegal acquisition or possession of exotic wildlife species.

    Q.What are Zoonotic Diseases? Discuss how the illicit trade in wildlife has resulted in the spread of zoonotic diseases of the scale of the ongoing COVID-19?

    Voluntary disclosure scheme

    • The MoEFCC has come out with an advisory on a one-time voluntary disclosure amnesty scheme.
    • It allows owners of exotic live species that have been acquired illegally, or without documents, to declare their stock to the government between June and December 2020.
    • The scheme aims to address the challenge of zoonotic diseases and regulate their import. In its current form, however.
    • It shall develop an inventory of exotic live species for better compliance under the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES).
    • However, the amnesty scheme is just an advisory, not a law

    What kind of exotic wildlife is covered?

    • The advisory has defined exotic live species as animals named under the Appendices I, II and III of the CITES.
    • It does not include species from the Schedules of the Wild Life (Protection) Act 1972.
    • So, a plain reading of the advisory excludes exotic birds from the amnesty scheme.

    Why need such a scheme?

    • The Directorate of Revenue Intelligence (DRI), which enforces anti-smuggling laws, says India has emerged as a big demand centre for exotic birds and animals.
    • There has been an increase in smuggling of endangered species from different parts of the world.
    • Most of these exotic wildlife is imported through Illegal channels and then sold in the domestic market as pets.
    • The long international border and air routes are used to source consignments from Bangkok, Malaysia and other top tourist destinations in South East Asia, as well as from Europe into India.

    Back2Basics: CITES

    • CITES stands for the Convention on International Trade in Endangered Species of Wild Fauna and Flora.
    • It is as an international agreement aimed at ensuring “that international trade in specimens of wild animals and plants does not threaten their survival”.
    • It was drafted after a resolution was adopted at a meeting of the members of the International Union for Conservation of Nature (IUCN) in 1963.
    • It entered into force on July 1, 1975, and now has 183 parties.
    • The Convention is legally binding on the Parties in the sense that they are committed to implementing it; however, it does not take the place of national laws.
    • India is a signatory to and has also ratified CITES convention in 1976.

    CITES Appendices

    • CITES works by subjecting international trade in specimens of selected species to certain controls.
    • All import, export, re-exports and introduction from the sea of species covered by the convention has to be authorized through a licensing system. It has three appendices:
    1. Appendix I includes species threatened with extinction. Trade-in specimens of these species are permitted only in exceptional circumstances.
    2. Appendix II provides a lower level of protection.
    3. Appendix III contains species that are protected in at least one country, which has asked other CITES Parties for assistance in controlling trade.

  • Mystery illness in Eluru

    Over 550 people in Eluru town of Andhra Pradesh’s West Godavari district have been suffering from convulsions, seizures, dizziness and nausea.

    Q.Which of the following can be found as pollutants in the drinking water in some parts of India?

    1. Arsenic
    2. Sorbitol
    3. Fluoride
    4. Formaldehyde
    5. Uranium

    Select the correct answer using the codes given below:

    (a) 1 and 3 only

    (b) 2, 4 and 5 only

    (c) 1, 3 and 5 only

    (d) 1, 2, 3, 4 and 5

    Eluru illness

    • The All India Institute of Medical Sciences (AIIMS) has found traces of lead and nickel in blood samples of 25 victims out of the 45 samples sent by the state government.
    • The primary suspicion is on water contamination by heavy metals. Scientists suspect that pesticide or insecticide has seeped into drinking water sources.
    • Experts from Hyderabad who collected water, blood, and food samples say there are indications of lead contamination but can confirm this only after detailed test reports.

    Possible cause: Water contamination

    • Eluru receives water through canals from both Godavari and Krishna rivers.
    • The canals pass through agricultural fields where runoff laced with pesticides mixes with water in the canals. Many aspects of the mystery illness have baffled scientists.
    • People who only use packaged drinking water have also fallen sick.

  • Places in news: ‘Mini Kaziranga’

    (a) 1 only

    (b) 2 only

    (c) 1 and 3 only

    (d) 1, 2 and 3

    About Pobitora Wildlife Sanctuary

    • Pobitora WLS is located on the southern bank of the Brahmaputra in Morigaon district in Assam.
    • It was declared in 1987 and covers 38.85 km2 (15.00 sq mi), providing grassland and wetland habitat for the Indian rhinoceros.
    • It provides a habitat and food resource for the Indian rhinoceros, hosting Assam’s second-largest population.
    • Other mammals occurring in the sanctuary are golden jackal, wild boar and feral water buffalo.
    • Barking deer, Indian leopard and rhesus macaque live foremost in the hilly parts. It is an Important Bird Area and home for more than 2000 migratory birds and various reptiles.

    Why in news?

    • Pobitora is running a successful Rhino breeding program within its sanctuary.
    • It is running under the government as “Indian Rhino vision 2020”.

    Back2Basics: Kaziranga National Park and Tiger Reserve

    • The KNTPR is a national park in the Golaghat, Karbi Anglong and Nagaon districts of the state of Assam.
    • The sanctuary, which hosts two-thirds of the world’s great one-horned rhinoceroses, is a World Heritage Site.
    • Kaziranga is home to the highest density of tigers among protected areas in the world and was declared a Tiger Reserve in 2006 (now the highest tiger density is in Orang National Park, Assam).
    • The park is home to large breeding populations of elephants, wild water buffalo, and swamp deer.
    • It is also recognized as an Important Bird Area by BirdLife International for the conservation of avifaunal species.

  • Eco-ducts or Eco-bridges and their significance

    Ramnagar Forest Division in Nainital district, Uttarakhand, recently built its first eco-bridge for reptiles and smaller mammals.

    Q.Discuss how Eco-ducts or eco-bridges provide the best alternative for wildlife connectivity which is disrupted because of manmade highways. Also, discuss various challenges in building such bridges.

    What are Eco-bridges?

    • Eco-ducts or eco-bridges aim to enhance wildlife connectivity that can be disrupted because of highways or logging.
    • These include canopy bridges (usually for monkeys, squirrels and other arboreal species); concrete underpasses or overpass tunnels or viaducts (usually for larger animals); and amphibian tunnels or culverts.
    • Usually, these bridges are overlaid with planting from the area to give it a contiguous look with the landscape.

    Why need such bridges?

    • There are many roadkills on this route, especially of reptiles such as the monitor lizard.
    • The bridge is an awareness-building mechanism for this very congested tourist route.
    • These bridges are a way to see how we can preserve the ecosystem necessary for reptiles that feed on insects, for snakes that feed on reptiles, and for eagles that feed on snakes.

    Need of the hour

    • A 2020 study by the Wildlife Institute of India (WII) noted that nearly 50,000 km of road projects have been identified for construction over the next five to six years.
    • Many highways are being upgraded to four lanes.
    • The National Tiger Conservation Authority had identified three major sites that were cutting across animal corridors.
    • These including National Highway 37 through the Kaziranga-Karbi Anglong landscape in Assam, and State Highway 33 through the Nagarhole Tiger Reserve in Karnataka.

    Some considerations

    • The span and distribution of eco-bridges should depend on animal movement patterns.
    • The bigger bridges will see sambar, spotted deer, nilgai, wild pig using them, while for tigers or leopards if the bridge is 5m or 500 m, it doesn’t bother them.
    • But some animals like the deers, which prefer closed habitats, need smaller bridges.

    Some successes

    • The observation on NH 44, which intersects Kanha-Pench and Pench-Navegaon-Nagzira corridors in various sections, is a success.
    • With five animal underpasses and four minor bridges on the 6.6-km road within the forests, it’s one of India’s success stories.

    Such bridges in news

    • One of the largest underpasses – 1.4km – for animal conservation in India is being built along the Madhya Pradesh-Maharashtra border.
    • Other proposals include the Chennai-Bangalore National Highway, in the Hosur-Krishnagiri segment, near reserve forests for elephant crossings, and in the Tadoba-Andhari Tiger Reserve in Chandrapur, Maharashtra.

  • Jadav Payeng: The Forest Man of India

    Jadav Payeng, known as ‘The Forest Man of India’, takes us through his journey of grit that saw a desert turning into a forest. His story is been depicted through an upcoming trilingual film.

    We knew about the mountain man in India. We have also had the Forest Man of India who is also a living inspiration for successful afforestation. We can quote such examples in essays very well.

    Who is Jadav Payeng?

    • Jadav “Molai” Payeng (born 1963) is an environmental activist and forestry worker from Majuli Island popularly known as the Forest Man of India.
    • He was born in the indigenous Mising tribe of Assam.
    • Over the course of several decades, he has planted and tended trees on a sandbar of the river Brahmaputra turning it into a forest reserve.
    • The forest, called Molai forest after him is located near Kokilamukh of Jorhat, Assam, India and encompasses an area of about 1,360 acres / 550 hectares.
    • In 2015, he was honoured with Padmashri, the fourth highest civilian award in India.

    His work

    • The forest, which came to be known as Molai forest, now houses Bengal tigers, Indian rhinoceros, and over 100 deer and rabbits.
    • Molai forest is also home to elephants and several varieties of birds, including a large number of vultures.
    • Bamboo covers an area of over 300 hectares.

    World Heritage Irrigation Structure (WHIS)

    • The International Commission on Irrigation and Drainage (ICID) annually recognizes irrigation structures of international significance like UNESCO’s World Heritage Sites.
    • The recognition is aimed at recognizing and tracing the history of and understanding the evolution of irrigation in civilizations across the world.
    • It also aims at understanding the philosophy and wisdom on sustainable irrigation from these structures and to preserve them for posterity.

    Criteria for consideration

    • Major criteria for WHIS entail that a structure should be more than 100 years old, should be functional, achieving food security and have archival value.
    • Each site is evaluated based on its merits first by the state government.
    • The proposal is then sent to the Centre and a team from CWC carries out an on-ground survey to verify details.

    Which are the Indian sites?

    • The sites are Cumbum Tank, Kurnool-Cuddapah Canal, Porumamilla Tank (Anantharaja Sagaram) in Andhra Pradesh and 490-year-old Dhamapur Lake in Maharashtra’s Sindhudurg district.
    • In 2018, Pedda Cheru Tank in Kamareddy district and Sadarmat Anicut in Nirmal district, both in Telangana, were named as WHIS sites.

    Other sites

    • The rest include Tianbao Weir in China at number one followed by Longshou Canal and ancient Luohe river irrigation district, China.

    • ICID mission covers the entire spectrum of agricultural water management practices ranging from rainfed agriculture to supplemental irrigation, land drainage, deficit irrigation to full irrigation, etc.

  • 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.

    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.

  • 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.

  • Understanding the interplay between subsidies and agri-pollution

    Agriculture’s contribution to air pollution

    • Agriculture’s contribution to air pollution runs deeper than what happens between crop seasons.
    • The Indo-Gangetic plain is also one of the world’s largest and rapidly-growing ammonia hotspots.
    • Atmospheric ammonia, which comes from fertiliser use, animal husbandry, and other agricultural practices, combines with emissions from power plants, transportation and other fossil-fuel burning to form fine particles.

    Impact of pollution on agriculture

    • It is important to note that agriculture is a victim of pollution as well as its perpetrator.
    • Particulate matter and ground-level ozone formed from industrial, power plant, and transportation emissions among other ingredients cause double-digit losses in crop yields.
    • Ozone damages plant cells, handicapping photosynthesis, while particulate matter dims the sunlight that reaches crops.
    • Agriculture scientist Tony Fischer’s 2019 estimates of the two pollutants’ combined effect suggest that as much as 30 per cent of India’s wheat yield is missing (Sage Journals, Outlook on Agriculture).
    • Earlier, B Sinha et al (2015), in Atmospheric Chemistry and Physics Discussions, found that high ozone levels in parts of Haryana and Punjab could diminish rice yields by a quarter and cotton by half.

    Role played by subsidies

    • The current system of subsidies is a big reason that there is stubble on these fields in the first place.
    • Free power — and consequently, “free” water, pumped from the ground — is a big part of what makes growing rice in these areas attractive.
    • Open-ended procurement of paddy, despite the bulging stocks of grains with the Food Corporation of India, adds to the incentives.
    • Subsidies account for almost 15 per cent of the value of rice being produced in Punjab-Haryana belt.
    • Fertiliser, particularly urea in granular form, is highly subsidised.
    • It is one of the cheapest forms of nitrogen-based fertiliser, easy to store and easy to transport, but it is also one of the first to “volatilise,” or release ammonia into the air.
    • This loss of nitrogen then leads to a cycle of more and more fertiliser being applied to get the intended benefits for crops.

    Way forward

    • We need to shift the nature of support to farmers from input subsidies to investment subsidies.
    • This could involve the conversion of paddy areas in this belt to orchards with drip irrigation, vegetables, corn, cotton, pulses and oilseeds.
    • All of the above consume much less water, much less power and fertilisers and don’t create stubble to burn.
    • A diversification package of, say, Rs 10,000 crore spread over the next five years, equally contributed by the Centre and states, may be the best way to move forward in reducing agriculture-related pollution.
    • The approach to diversification has to be demand-led, with a holistic framework of the value chain, from farm to fork and not just focused on production.
    • On the fertiliser front, it would be better to give farmers input subsidy in cash on per hectare basis, and free up the prices of fertilisers completely.

    Conclusion

    Taken together, these measures could double farmers’ incomes, promote efficiency in resource use, and reduce pollution — a win-win solution for all.

  • 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.
