  • India offers ‘Panchamrita’ Strategy for Climate Conundrum at Glasgow

    PM Modi has proposed a five-fold strategy called the ‘Panchamrita’ for India to play its part in helping the world get closer to 1.5 degrees Celsius on the first day of the global climate meeting in Glasgow.

    What is Panchamrita?

    • ‘Panchamrita’ is a traditional method of mixing five natural foods — milk, ghee, curd, honey and jaggery. These are used in Hindu and Jain worship rituals. It is also used as a technique in Ayurveda.
    • The PM euphemistically termed his scheme as ‘Panchamrita’ meaning the ‘five ambrosia’.
    • Under Panchamrita’, India will:
    1. Get its non-fossil energy capacity to 500 gigawatts by 2030
    2. Meet 50 per cent of its energy requirements till 2030 with renewable energy
    3. Reduce its projected carbon emission by one billion tonnes by 2030
    4. Reduce the carbon intensity of its economy by 45 per cent by 2030
    5. Achieve net zero by 2070

    Key takeaways of PM’s speech

    (a) Commitment for climate action

    • India consists of 17 per cent of the world’s population but contribute only five per cent of emissions.
    • Yet, it has left no stone unturned in doing our bit to fight climate change.
    • At Paris, India was making promises not to the world but to itself and 1.3 billion Indians, PM said.

    (b) Climate finance

    • The 2015 Paris CoP where the Paris Agreement was signed was not a summit but a sentiment.
    • The promises made till now on climate finance were useless.
    • When we all are increasing our ambitions on climate action, the world’s ambition could not stay the same on climate finance as was agreed at the time of Paris.

    (c) India’s track record

    • India was fourth as far as installed renewable energy capacity was concerned.
    • The Indian Railways has pledged to make itself net-zero by 2030. This will result in an annual 60 million tonnes reduction in emissions.
    • India initiated the International Solar Alliance for solar energy.
    • It has also set up the coalition for disaster resilient infrastructure for climate adaptation.

  • [pib] BASIC Countries

    The Union Environment Minister has delivered the statement on behalf of the BASIC group of countries at the UN Climate Change Conference underway at Glasgow.

    Who are the BASIC Countries?

    • The BASIC countries (also Basic countries or BASIC) are a bloc of four large newly industrialized countries – Brazil, South Africa, India and China.
    • It was formed by an agreement on 28 November 2009.
    • The four committed to act jointly at the Copenhagen climate summit, including a possible united walk-out if their common minimum position was not met by the developed nations.
    • This emerging geopolitical alliance, initiated and led by China, then brokered the final Copenhagen Accord with the United States.

    What is the Copenhagen Accord?

    • The Copenhagen Accord is a document signed at COP 15 to the UNFCCC on 18 December 2009.
    • The Accord states that global warming should be limited to below 2.0 °C (3.6 °F).
    • It does not specify what the baseline is for these temperature targets (e.g., relative to pre-industrial or 1990 temperatures).
    • In January 2010, the Accord was described merely as a political agreement and not legally binding, as is argued by the US and Europe.
    • It is not legally binding and does not commit countries to agree to a binding successor to the Kyoto Protocol, whose round ended in 2012.
    • According to the UNFCCC, these targets are relative to pre-industrial temperatures.

  • Guidelines released for safe rescue, release of Ganges River Dolphins (GRDs)

    The Jal Shakti Ministry has released a guide for the safe rescue and release of stranded Ganges River Dolphins.

    Gangetic Dolphin

    • The Gangetic river system is home to a vast variety of aquatic life, including the Gangetic dolphin (Platanista gangetica).
    • The species, whose global population is estimated at 4,000, are (nearly 80%) found in the Indian subcontinent.
    • It is found mainly in the Indian subcontinent, particularly in Ganga-Brahmaputra-Meghna and Karnaphuli-Sangu river systems.
    • It is one of five species of river dolphin found around the world.
    • Only three species of freshwater dolphins are remaining on the earth after the functional extinction of the Chinese river Dolphin (Baiji) in 2006.

    Conservation status

    1. The GRDs have been designated the National Aquatic Animal of India since 2010.
    • It is listed as:
    1. Endangered under IUCN Red List
    2. Schedule I of the Indian Wildlife (Protection) Act (1972)
    3. Appendix I of the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES)

    About the guidelines

    • The document has been prepared by the Turtle Survival Alliance, India Program and Environment, Forest and Climate Change Department (EFCCD), Uttar Pradesh.
    • The guide has been drawn from years of experience of the organization while rescuing 25 Ganges River Dolphins (GRDs) stranded in irrigation canals.

    Various threats

    • They often accidentally enter canal channels in northern India and are often entrapped, and die as they are unable to swim up against the gradient.
    • They are eventually harassed by the locals.
    • Opportunistic poaching for meat and oil in certain pockets of the country is another big threat.

  • US research highlights Indian farming practices

    A paper has recently published in the US has found that Integrated farming with intercropping increases food production while reducing environmental footprint.

    What is the finding?

    This work found that:

    1. Relay planting enhances yield
    2. Within-field rotation or strip rotation allowing strips for planting other plants (such as grass, fruits) besides the major crop was more fruitful
    3. Soil munching that is, available means such as crop straw, in addition to the major crop such as wheat or rice, and
    4. No-till or reduced tillage, which increases the annual crop yield up by 15.6% to 49.9%, and decreasing the environmental footprint by 17.3%, compared with traditional monoculture cropping

    Various terms mentioned

    [A] Relay planting

    • Relay planting means the planting of different crops in the same plot, one right after another, in the same season.
    • Examples of such relay cropping would be planting rice (or wheat), cauliflower, onion, and summer gourd (or potato onion, lady’s fingers and maize), in the same season.
    • Benefits: It is less risk since you do not have to depend on one crop alone. It also means better distribution of labour, insects spread less, and any legumes actually add nitrogen to the soil.

    [B] Strip cropping

    • Strip cropping has been used in the U.S. (where the fields are larger than those in India), where they grow wheat, along with corn and soybean, in the same farm in an alternative manner.
    • However, this needs large lands. The land is divided into strips, and strips of grass are left to grow between the crops.
    • Benefits: Planting of trees to create shelters has helped in stabilising the desert in Western India.

    [C] Soil mulching and no-till

    • Soil mulching requires keeping all bare soil covered with straw, leaves, and the like, even when the land is in use.
    • Benefits: Erosion is curtailed, moisture retained, and beneficial organisms, such as earthworms, kept in place. The same set of benefits are also offered by not tilling the soil.

    Significance of the findings

    • This research has led to the conclusion that small farm holders can grow more food and have reduced environmental footprint.
    • Current statistics reveal that our country has a significant population of small farmers, many owning less than 2 hectares of land.
    • About 70% of its rural households still depend primarily on agriculture for their livelihood, with 82% of farmers being small and marginal.

  • What is Climate Vulnerability Index?

    Environmental think tank Council on Energy, Environment and Water has carried a first-of-its-kind district-level climate vulnerability assessment, or Climate Vulnerability Index (CVI).

    Climate Vulnerability Index

    • The Index takes into account certain indicators when assessing the preparedness of a state or district.
    • It considers:
    1. Exposure (that is whether the district is prone to extreme weather events)
    2. Sensitivity (the likelihood of an impact on the district by the weather event)
    3. Adaptive capacity (what the response or coping mechanism of the district is)

    Significance of CVI

    • CVI helps map critical vulnerabilities and plan strategies to enhance resilience and adapt by climate-proofing communities, economies and infrastructure.
    • Instead of looking at climate extremes in isolation, the study looks at the combined risk of hydro-met disasters, which is floods, cyclones and droughts, and their impact.
    • The study does not take into consideration other natural disasters such as earthquakes.

    Why does India need a climate vulnerability index?

    • According to Germanwatch’s 2020 findings, India is the seventh-most vulnerable country with respect to climate extremes.
    • Extreme weather events have been increasing in the country such as supercyclone Amphan in the Bay of Bengal, which is now the strongest cyclone to be recorded in the country.
    • Recent events such as the landslides and floods in Uttarakhand and Kerala, have also increased in the past decade.
    • Further, the IPCC states that every degree rise in temperature will lead to a three per cent increase in precipitation, causing increased intensification of cyclones and floods.

    Key findings of the CVI

    According to CVI, Assam, Andhra Pradesh, Maharashtra, Karnataka and Bihar are most vulnerable to extreme climate events such as floods, droughts and cyclones in India.

    • 183 hotspot districts are highly vulnerable to more than one extreme climate events
    • 60% of Indian districts have medium to low adaptive capacity in handing extreme weather events – these districts don’t have robust plans in place to mitigate impact
    • North-eastern states are more vulnerable to floods
    • South and central are most vulnerable to extreme droughts
    • 59 and 41 per cent of the total districts in the eastern and western states, respectively, are highly vulnerable to extreme cyclones.

    Best performing states

    • Kerala and West Bengal have performed well comparatively, despite both being coastal states and dealing with the threat of cyclones and floods annually.
    • The reason why these states have performed better is that they have stepped up their climate action plans as well as preparedness to handle an extreme weather event.

    Key recommendations

    • Develop a high-resolution Climate Risk Atlas (CRA) to map critical vulnerabilities
    • Establish a centralised climate-risk commission to coordinate the environmental de-risking mission.
    • Undertake climate-sensitivity-led landscape restoration focused on rehabilitating, restoring, and reintegrating natural ecosystems as part of the developmental process.
    • Integrate climate risk profiling with infrastructure planning to increase adaptive capacity.
    • Provide for climate risk-interlinked adaptation financing by creating innovative CVI-based financing instruments that integrate climate risks for an effective risk transfer mechanism.

  • Sundarbans among 5 sites with highest ‘Blue Carbon’ globally

    India’s Sundarbans National Park is among five sites that have the highest blue carbon stocks globally, according to a new assessment.

    Highlights of the study

    • ‘World Heritage forests’ are now releasing more carbon than they are absorbing, primarily due to human activity and climate change, according to the assessment.
    • UNESCO lists 50 sites across the globe for their unique marine values. These represent just one per cent of the global ocean area.
    • But they comprise at least 15 per cent of global blue carbon assests.

    Try this question from CSP 2021:

    Q. What is blue carbon?

    (a) Carbon captured by oceans and coastal ecosystems

    (b) Carbon sequestered in forest biomass and agricultural soils

    (c) Carbon contained in petroleum and natural gas

    (d) Carbon present in atmosphere

    Back2Basics: Types of Carbon

    • Brown Carbon: It is brown smoke released by the combustion of organic matter.
    • Black Carbon: It is also a greenhouse gas and causes more pollution than Brown Carbon. The particles leftover from incomplete combustion of fossil fuels (soot and dust). It has a greater effect on radiation transmission.
    • Green Carbon: Carbon incorporated into plant biomass and the soils below. Green carbon is carbon removed by photosynthesis and stored in the plants and soil of natural ecosystems.
    • Blue Carbon: Blue Carbon refers to coastal, aquatic and marine carbon sinks held by the indicative vegetation, marine organism and sediments.

  • Why India shouldn’t sign on to net zero

    Context

    The recent report of the Intergovernmental Panel on Climate Change made it clear that limiting the increase in the world’s average temperature from pre-industrial levels to those agreed in the Paris Agreement requires global cumulative emissions of carbon dioxide to be capped at the global carbon budget.

    Understanding why reaching net zero by itself is irrelevant to forestalling dangerous warming

    • The promise of when you will turn off the tap does not guarantee that you will draw only a specified quantity of water.
    • The top three emitters of the world — China, the U.S. and the European Union — even after taking account of their net zero commitments and their enhanced emission reduction commitments for 2030, will emit more than 500 billion tonnes of carbon dioxide before net zero.
    • These three alone will exceed the limit of about 500 billion tonnes from 2020 onwards, for even odds of keeping global temperature increase below 1.5°C.

    Issues with ‘net zero’ target

    • Neither the Paris Agreement nor climate science requires that net zero be reached individually by countries by 2050, the former requiring only global achievement of this goal “in the second half of the century”.
    • Claims that the world “must” reach specific goals by 2030 or 2050 are the product of specific economic models for climate action.
    • They front-load emission reduction requirements on developing countries, despite their already low emissions, to allow the developed world to backload its own, buying time for its own transition.
    • These stringent limits on future cumulative emissions post 2020, amounting to less than a fifth of the total global carbon budget, is the result of its considerable over-appropriation in the past by the global North.
    • Promises of net zero in their current form perpetuate this hugely disproportionate appropriation of a global commons, while continuing to place humanity in harm’s way.

    Suggestions for India

    • India is responsible for no more than 4.37% cumulative emissions of carbon dioxide since the pre-industrial era, even though it is home to more than a sixth of humanity.
    • India’s per capita emissions are less than half the world average, less than one-eighth of the U.S.’s.
    • For India to declare net zero now is to accede to the further over-appropriation of the global carbon budget by a few.
    • India’s contribution to global emissions, in both stock and flow, is so disproportionately low that any sacrifice on its part can do nothing to save the world.
    • India, in enlightened self-interest, must now stake its claim to a fair share of the global carbon budget.
    • Technology transfer and financial support, together with “negative emissions”, if the latter succeeds, can compensate for the loss of the past.
    • Such a claim by India provides it greater, and much-needed long-term options.
    • It enables the responsible use of coal, its major fossil fuel resource, and oil and gas, to bootstrap itself out of lower-middle-income economy status and eradicate poverty, hunger and malnutrition for good.
    • India’s resource-strapped small industries sector needs expansion and modernisation.
    • The agriculture sector, the second-largest source of greenhouse gas emissions for India after energy, needs to double its productivity and farmers’ incomes and build resilience.
    •  Infrastructure for climate resilience in general is critical to future adaptation to climate change.
    • All of these will require at least the limited fossil fuel resources made available through a fair share of the carbon budget.

    Conclusion

    Without restriction of their future cumulative emissions by the big emitters, to their fair share of the global carbon budget, and the corresponding temperature target that they correspond to made clear, India cannot sign on to net zero.

  • Podu Land issue in Telangana

    The Telangana government has decided to move landless, non-tribal farmers engaged in Podu shifting cultivation inside forests to peripheral areas as it looks to combat deforestation.

    What is Shifting Cultivation?

    • Shifting cultivation is a form of agriculture or a cultivation system, in which, at any particular point in time, a minority of ‘fields’ are in cultivation and a majority are in various stages of natural re-growth.
    • Over time, fields are cultivated for a relatively short time, and allowed to recover, or are fallowed, for a relatively long time.
    • Eventually, a previously cultivated field will be cleared of the natural vegetation and planted in crops again.
    • Fields in established and stable shifting cultivation systems are cultivated and fallowed cyclically.
    • This type of farming is also called jhumming in India.

    What is Podu?

    • Podu is a traditional system of cultivation used by tribes in India, whereby different areas of jungle forest are cleared by burning each year to provide land for crops.
    • The word comes from the Telugu language.
    • Podu is a form of shifting agriculture using slash-and-burn methods.

    Issue in Telangana

    • Shifting cultivation continues to be a predominant agricultural practice in many parts of India, despite state discouragement and multipronged efforts.
    • Telangana government has red-flagged encroachment of forests by non-tribals, who are indulging in the practice of shifting agriculture (podu).
    • Several political leaders have raised the issues of shifting agriculture and deforestation wherein encroachers clear a portion of land.
    • The government now wants to shift out all farmers from the forests to the periphery by allotting lands to them for cultivation.

    Impact of the move

    • Tribal farmers who have been traditionally cultivating for decades will not be affected by this drive against illegal encroachers.
    • The government has, in fact, given land ownership titles to tribals.
    • Other encroaching farmers will be shifted out.

    Back2Basics: Various shifting cultivation in India

    Type Place of practice
    Jhum North-eastern India
    Vevar and Dahiyaar Bundelkhand Region (Madhya Pradesh)
    Deepa Bastar District (Madhya Pradesh)
    Zara and Erka Southern States
    Batra South-eastern Rajasthan
    Podu Andhra Pradesh
    Kumari Hilly Region of the Western Ghats of Kerala

  • Prakritik Kheti Khushhal Yojana (PK3Y)

    Women farmers in the hill State of Himachal Pradesh are gradually turning to non-chemical, low cost “natural farming”, under the Prakritik Kheti Khushhal Yojana (PK3Y).

    Prakritik Kheti Khushhal Yojana

    • Launched in 2018, the State’s PK3Y is promoting the climate resilient Subhash Palekar Natural Farming (SPNF), also called ‘Zero Budget Natural Farming’.
    • Over 1.5 lakh farmers have been trained in natural farming in the State so far, with substantial numbers of women participants.

    About Zero Budget Natural Farming (ZBNF)?

    • ZBNF is a set of farming methods, and also a grassroots peasant movement, which has spread to various states in India.
    • Subhash Palekar perfected it during the 1990s at his farm in Amravati district in Maharashtra’s drought-prone Vidarbha region.
    • According to the “zero budget” concept, farmers won’t have to spend any money on fertilisers and other agricultural inputs.
    • Over 98% of the nutrients that crops require — carbon dioxide, nitrogen, water, solar energy — are already present in nature.
    • The remaining 1.5-2% are taken from the soil, after microorganisms convert them from “non-

    Four Wheels of ZBNF

    The “four wheels” of ZBNF are ‘Jiwamrita’, ‘Bijamrita’, ‘Mulching’ and ‘Waaphasa’.

    • Jiwamrita is a fermented mixture of cow dung and urine (of desi breeds), jaggery, pulses flour, water and soil from the farm bund.
    • This isn’t a fertiliser, but just a source of some 500 crore micro-organisms that can convert all the necessary “non-available” nutrients into “available” form.
    • Bijamrita is a mix of desi cow dung and urine, water, bund soil and lime that is used as a seed treatment solution prior to sowing.
    • Mulching, or covering the plants with a layer of dried straw or fallen leaves, is meant to conserve soil moisture and keep the temperature around the roots at 25-32 degrees Celsius, which allows the microorganisms to do their job.
    • Waaphasa, or providing water to maintain the required moisture-air balance, also achieves the same objective.

    Astra’s of ZBNF against pest attacks

    • ZBNF advocates the use of special ‘Agniastra’, ‘Bramhastra’ and ‘Neemastra’ concoctions.
    • They are based on cow urine and dung, plus pulp from leaves of neem, white datura, papaya, guava and pomegranates — for controlling pest and disease attacks.

    Is it organic farming?

    • ZBNF uses farmyard manure or vermicompost.

    However, not all farmers are convinced about ZBNF. Why?

    • Cost of labour: The cost of labour for collection of dung and urine, apart from the other inputs used in preparation of Jiwamrita, Neemastra or Bramhastra is quit higher.
    • Bovine cost: Keeping cows is also a cost that has to be accounted for. Farmers cannot afford to keep desi cows that yield very little milk.
    • Vulnerability to pest attacks:  ZBNF is scarcely practiced.  The crop grown would be vulnerable to attacks by insects and pests have already become pest-immune.

  • Species in news: Bengal Florican

    Environmentalists have recently written to the Assam government on the urgent need to prevent land-use changes at Kokilabari Seed Farm in the state to protect Bengal floricans and other species.

    Bengal Florican

    • The Bengal florican also called Bengal bustard, is a bustard species native to the Indian subcontinent, Cambodia, and Vietnam.
    • Fewer than 1,000 individuals were estimated to be alive as of 2017.
    • It has two disjunct populations, one in the Indian subcontinent, another in Southeast Asia.
    • The former occurs from Uttar Pradesh (India) through the Terai of Nepal to Assam (where it is called ulu mora) and Arunachal Pradesh in India, and historically to Bangladesh.
    • It has a very small, rapidly declining population largely as a result of the widespread loss of its grassland habitat.

    Conservation status

    • IUCN Red List Status: Critically Endangered
    • CITES: Appendix I
