  • Species in news: Himalayan Serow

    A Himalayan Serow has been sighted for the first time in the Himalayan cold desert region.

    Try this MCQ:

    Q.In which one of the following State, the Rupi Bhaba Wildlife Sanctuary is located?

    (a) Himachal Pradesh

    (b) Manipur

    (c) Meghalaya

    (d) Uttarakhand

    Himalayan Serow

    • Himalayan Serow resembles a cross between a goat, a donkey, a cow, and a pig.
    • They are herbivores and are typically found at altitudes between 2,000 metres and 4,000 metres (6,500 to 13,000 feet).
    • They are known to be found in eastern, central, and western Himalayas, but not in the Trans Himalayan region.
    • They are a medium-sized mammal with a large head, thick neck, short limbs, long, mule-like ears, and a coat of dark hair.
    • There are several species of Serow s, and all of them are found in Asia.

    Its’ conservation status

    • According to the IUCN, Himalayan Serow s have experienced significant declines in population size, range size and habitat in the last decade, and this is expected to continue due to intensive human impact.
    • Previously assessed as ‘near threatened’, the Himalayan Serow is now been categorised as ‘vulnerable’ in the IUCN Red List of Threatened Species.
    • It is listed under Schedule I of The Wildlife Protection Act, 1972, which provides absolute protection.

    What is so unusual this time?

    • The animal was spotted by locals and wildlife officials at a riverside rocky wall near Hurling village in Spiti, Himachal Pradesh.
    • This is the first recorded human sighting of the Serow in Himachal Pradesh.
    • Serow s are generally not found at this altitude, and never before has a Serow been seen in the Himalayan cold desert.
    • Wildlife officials believe this particular animal may have strayed into the Spiti valley from the Rupi Bhaba Wildlife Sanctuary in adjoining Kinnaur.

  • Shola Sky Islands of the Western Ghats

    Tropical montane grasslands (TMG) in the Shola Sky Islands of the Western Ghats have suffered big losses due to invasions by exotic trees.

    Try this PYQ:

    Q.In India, which type of forest among the following occupies the largest area?
    (a) Montane Wet Temperate Forest
    (b) Sub – tropical Dry Evergreen Forest
    (c) Tropical Moist Deciduous Forest
    (d) Tropical Wet Evergreen Forest

    Sky Islands

    • “Sky islands” are the tops of tall mountains that become environmentally isolated from each other even if they are close together, geographically speaking.
    • The Western Ghats are a mountain chain in southwest India home to spectacular and unique sky islands.
    • The peaks of the Western Ghats, ranging between 3,000 and 8,500 feet above sea level, host an almost unbelievable array of microclimates, looking like “patches of forests floating in a sea of grasslands.

    What are TMGs?

    • TMG are high elevation grasslands forming only 2% of all grasslands in the world.
    • Among their functions is regulating the global carbon cycle and serving as a source of water to downstream communities.
    • Researchers say grasslands do not benefit from conservation and restoration efforts afforded to tropical montane forests, possibly due to limited information.

    Treasures of Shola

    • One of the specific habitats unique to the sky islands of this area is a type of low-temperature, high-humidity tropical cloud forest full of stunted trees mixed with grasslands called the Shola.
    • The Shola forests of South derive their name from the Tamil word solai, which means a ‘tropical rain forest’.
    • Classified as ‘Southern Montane Wet Temperate Forest’ the Sholas are found in the upper reaches of the Nilgiris, Anamalais, Palni hills, Kalakadu, Mundanthurai and Kanyakumari in the states of Tamil Nadu and Kerala.
    • These forests are found sheltered in valleys with sufficient moisture and proper drainage, at an altitude of more than 1,500 metres.

    Various threats to them

    • Loss of grasslands due to invasive exotic trees is a “novel threat” through the establishment and expansion of exotic tree plantations.
    • These exotic trees include acacias, pines and eucalyptus, shrinking the range sizes of endemic species, including plants, birds, amphibians and mammals.
    • In the Western Ghats, 23% of montane grasslands were reportedly converted into invasive exotic tree cover over a period of 44 years.
    • Attempts to manage invasive exotic trees in montane grasslands incorporated approaches that include prevention and mechanical, chemical and biological control.
    • For invasive species such as Acacia mearnsii that grow rapidly and disperse seeds widely, removing mature trees is often ineffective.

  • Five years of Paris Agreement

     Climate Ambition Summit was held on the 5th anniversary of the Paris Agreement. The article takes stock of the progress made on climate action in the last 5 years.

    The Paris Agreement

    • The Paris Agreement is a legally binding international treaty on climate change. It was adopted by 196 Parties at COP 21 in Paris, on 12 December 2015 and entered into force on 4 November 2016.
    • Its goal is to limit global warming to well below 2, preferably to 1.5 degrees Celsius, compared to pre-industrial levels.
    • To achieve this long-term temperature goal, countries aim to reach global peaking of greenhouse gas emissions as soon as possible to achieve a climate-neutral world by mid-century.
    • It is a landmark process because, for the first time, a binding agreement brings all nations into a common cause to undertake ambitious efforts to combat climate change and adapt to its effects.

    How does it function?

    • Implementation of the Paris Agreement requires economic and social transformation, based on the best available science.
    • The Agreement works on a 5- year cycle of increasingly ambitious climate action carried out by countries.
    • By 2020, countries submit their plans for climate action known as nationally determined contributions (NDCs).

    NDCs

    • In their NDCs, countries communicate actions they will take to reduce their Greenhouse Gas emissions in order to reach the goals of the Paris Agreement.
    • Countries also communicate in the NDCs actions they will take to build resilience to adapt to the impacts of rising temperatures.

    Long-Term Strategies

    • To better frame the efforts towards the long-term goal, the Paris Agreement invites countries to formulate and submit by 2020 long-term low greenhouse gas emission development strategies (LT-LEDS).
    • LT-LEDS provide the long-term horizon to the NDCs. Unlike NDCs, they are not mandatory.
    • Nevertheless, they place the NDCs into the context of countries’ long-term planning and development priorities, providing a vision and direction for future development.

    Progress made after 5 years

    • All states have submitted their national contributions to mitigate and adapt to climate change.
    • However, these contributions are radically insufficient to reach the “well below 2 degrees Celsius” limit and are even further from the “1.5 degrees Celsius” temperature limit identified in the Paris Agreement.
    • This initial shortfall was expected — the logic of the Paris Agreement relied on iterative scaling up of national targets over time to bridge the gap.

    Are countries scaling up the targets

    • Although 151 states have indicated that they will submit stronger targets before December 31, only 13 of them, covering 2.4 per cent of global emissions, have submitted such targets.
    • While states have been slow to update their national contributions for 2025-2030, several have announced “net zero” targets in the recent past.
    • All G-7 states except the US and 11 G20 members have mid-century (2050 or 2060) net zero targets -carbon dioxide or other GHGs.
    • The Joe Biden administration is also expected to join this group.

    Issues in Net Zero targets

    1) Credibility of the commitments

    • First, the credibility check — are these long-term net zero goals aligned with short-term actions, policies and measures?
    • The IPCC 1.5 degrees Celsius Report indicated that to stay within a reasonable chance of achieving 1.5 degrees Celsius, global carbon dioxide emissions have to fall by 45 per cent from the 2010 levels by 2030.
    • Current national contributions are not on track for such a fall.
    • For many there is a mismatch between short-term actions and long-term commitments.
    • Further, there is a significant “overshoot” in terms of GHGs in the short and medium-term, and a reliance on negative emissions technologies to get there in the long-term.

    2) Fixing accountability

    • Many net zero goals have not yet been embedded in national contributions and long-term strategies under the Paris Agreement.
    • In any case, accountability under the Paris Agreement is limited. States are not obliged to achieve their self-selected targets.
    • There is no mechanism to review the adequacy of individual contributions.
    • States are only asked to provide justifications for the fairness and ambition of their targets.
    • The transparency framework does not contain a robust review function, and the compliance committee is facilitative and limited to ensuring compliance with a short list of binding procedural obligations.
    • Accountability, therefore, has thus far been generated by non-state actors outside the UN regime rather than in the regime.

    3) Fairness of climate action

    •  The issue of equity and fairness, side-stepped in the Paris Agreement, is emerging in climate litigation before national and regional courts.
    • In the landmark Urgenda case (2019), the Dutch Supreme court considered “fair shares” when identifying benchmarks against which the Netherland’s national effort could be judged in the context of a collective action problem.
    • Issues of fairness and justice, both between and within generations, are “unavoidable”.

    India’s commitment

    In 2015, ahead of the UN significant climate conference in Paris, India announced three major voluntary commitments called the Nationally Determined Contributions (NDC):

    1. Improving the emissions intensity of its GDP by 33–35% by 2030 over 2005 levels
    2. Increasing the share of non-fossil fuels-based electricity to 40% by 2030 and
    3. Enhancing its forest cover, thereby absorbing 2.5 to 3 billion tonnes of carbon dioxide

    A success (?)

    • The Environment Minister said that we have achieved 21% of its emissions intensity reduction target as a proportion of its GDP in line with its pledge to a 33-35% reduction by 2030.
    • India was the only major G20 country that was on track towards keeping to its nationally determined commitments to halt runaway global warming.

    Conclusion

    Credible short-term commitments, with a clear pathway to medium-term decarbonisation, that take into account the multiple challenges states face, such as on air pollution, and development, might well be the more defensible choice for some.

  • 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.

    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.

    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.

    2. To identify and safeguard eco-friendly traditional farm practices and their associated landscapes, agricultural biodiversity and knowledge systems of the local communities.
    3. To provide Geographical Indication status to all the varieties of agricultural produce in such identified GIAHS.

    Select the correct answer using the code given below:

    (a) 1 and 3 only

    (b) 2 only

    (c) 2 and 3 only

    (d) 1, 2 and 3

    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.
    • It also includes Zarch and Moon Qanat both in Iran and Tenguiwa, Bizenkyo and Jyosai Gokuchi irrigation systems in Japan with Goseong Dumbeong in the Republic of Korea.

    About ICID

    • The ICID, established in 1950 is a leading scientific, technical, international not-for-profit, non-governmental organization.
    • It is a professional network of experts from across the world in the field of irrigation, drainage, and flood management.
    • The main mission is to promote ‘Sustainable agriculture water management’ to achieve ‘Water secure world free of poverty and hunger through sustainable rural development’.
    • 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.

  • The Paris agreement is no panacea

    The article highlights the fact that the provisions of the Paris Agreement would not be enough to avert the catastrophic and irreversible changes resulting from the global emissions. 

    Past efforts for environmental protection

    • The most hopeful time for global cooperation in protection of the planet was between the time of the Stockholm Conference (1972) and the time of the Rio Conference (1992).
    •  Scientific evidence about role anthropogenic emission in global warming led to political initiatives to harmonise development and environment.
    • The historic consensus in Rio led to the adoption of the UN Framework Convention on Climate Change (UNFCC).
    • A distinction was made between the “luxury emissions” of the developed countries and the survival emissions of the developed countries, which were allowed to increase.
    • Moreover, a huge financial package was approved to develop environment-friendly technologies in developing countries.

    Copenhagen Accord: Abandonment of Rio Principles

    • After the adoption of UNFCC, Conference of the Parties was held in Berlin in 1995 where developed countries backed off from their commitments.
    • Though the G-77 was split, the Rio principles were maintained.
    • The Kyoto Protocol enshrined the Rio principles.
    • It fixed emission targets for developed countries and a complex set of provisions was included to satisfy their interests.
    • The end of the Kyoto Protocol and the abandonment of the spirit of the Rio principles were reflected in the Copenhagen Accord (2009).
    • Argument given was that a global climate action plan would be possible only if all reductions of the greenhouse gases were made voluntary.

    Paris Agreement: Making emission reduction voluntary

    • The Paris Agreement moved away from the principle of common but differentiated responsibilities.
    • All countries were placed on an equal footing by making reduction of greenhouse gas emissions voluntary.
    • It requires all parties to put forward their best efforts through nationally determined contributions (NDCs)

    Shortcomings in Paris Agreement

    • The NDCs so far submitted will not result in the desired objective of limiting increase of global warming to below 2°C.
    • The Paris Agreement requires that all countries — rich, poor, developed, and developing — slash greenhouse gas emissions.
    • But no language is included on the commitments the countries should make.
    • Nations can voluntarily set their emissions targets and incur no penalties for falling short of their targets.
    •  Further temperature rise, even of 1.5°C, may result in catastrophic and irreversible changes.
    • Even a 1°C hotter planet is not a steady state, says a report of the Intergovernmental Panel on Climate Change (IPCC).

    Conclusion

    The IPCC report acknowledges that “the pathways to avoiding an even hotter world would require a swift and complete transformation not just of the global economy but of society too”. This will only be possible if the world rejects nationalism and parochialism and adopts collaborative responses to the crisis. The Paris Agreement falls short of that imperative.
