  • 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
    • Wildlife Protection Act of India, 1972: Schedule I

  • COP26 Climate Conference and Why it is important

    The UK will host the COP 26 UN Climate Change Conference from October 31 to November 12.

    Conference of Parties (CoP): A Backgrounder

    • The CoP comes under the United Nations Climate Change Framework Convention (UNFCCC) which was formed in 1994.
    • The UNFCCC was established to work towards “stabilisation of greenhouse gas concentrations in the atmosphere.”
    • It laid out a list of responsibilities for the member states which included:
    1. Formulating measures to mitigate climate change
    2. Cooperating in preparing for adaptation to the impact of climate change
    3. Promoting education, training and public awareness related to climate change
    • The UNFCCC has 198 parties including India, China and the USA. COP members have been meeting every year since 1995.

    COP1 to COP25: Key takeaways

    COP1: The first conference was held in 1995 in Berlin.

    COP3: It was held in Kyoto, Japan, in 1997, the famous Kyoto Protocol (w.e.f. 2005) was adopted. It commits the member states to pursue limitation or reduction of greenhouse gas emissions.

    COP8: India hosted the eighth COP in 2002 in New Delhi. It laid out several measures including, ‘strengthening of technology transfer… in all relevant sectors, including energy, transport and R&D,  and the strengthening of institutions for sustainable development.

    COP21: it is one of the most important that took place in 2015, in Paris, France. Here countries agreed to work together to ‘limit global warming to well below 2, preferably at 1.5 degrees Celsius, compared to pre-industrial levels.’

    Significance of COP26

    • The event will see leaders from more than 190 countries, thousands of negotiators, researchers and citizens coming together to strengthen a global response to the threat of climate change.
    • It is a pivotal movement for the world to come together and accelerate the climate action plan after the COVID pandemic.

    COP26 goals

    According to the UNFCCC, COP26 will work towards four goals:

    1. Secure global net-zero by mid-century and keep 1.5 degrees within reach
    • The UNFCCC recommends that countries ‘accelerate the phase-out of coal, curtail deforestation, speed up the switch to electric vehicles and encourage investment in renewables’ to meet this goal.
    1. Adapt to protect communities and natural habitats
    • Countries will work together to ‘protect and restore ecosystems and build defences, warning systems and resilient infrastructure and agriculture to avoid loss of homes, livelihoods and even lives.’
    1. Mobilise finance
    • To deliver on first two goals, developed countries must make good on their promise to mobilise at least $100bn in climate finance per year by 2020.
    1. Work together to deliver
    • Another important task at the COP26 is to ‘finalise the Paris Rulebook’. Leaders will work together to frame a list of detailed rules that will help fulfil the Paris Agreement.

    What India could do to reach its targets?

    • Update NDCs: It is time for India to update its Nationally Determined Contributions or NDCs. (NDCs detail the various efforts taken by each country to reduce the national emissions)
    • Effective planning: Sector by sector plans are needed to bring about development. We need to decarbonise the electricity, transport sector and start looking at carbon per passenger mile.
    • Energy transition: Aggressively figure out how to transition our coal sector
    • Robust legal framework: India also needs to ramp up the legal and institutional framework of climate change.

  • Climate finance

    Context

    In the run-up to the 26th UNFCCC media reports have claimed that developed countries are inching closer to the target of providing $100 billion annually. This view has been bolstered by the Organisation for Economic Co-operation and Development (OECD), which claimed that climate finance provided by developed countries had reached $78.9 billion in 2018.

    Issue of climate financing and claim of reaching the target of $100 billion

    • These claims reaching the target of $100 billion annually is erroneous.
    • First, the OECD figure includes private finance and export credits.
    • Public finance: Developing countries have insisted that developed country climate finance should be from public sources and should be provided as grants or as concessional loans.
    • However, the OECD report makes it clear that the public finance component amounted to only $62.2 billion in 2018, with bilateral funding of about $32.7 billion and $29.2 billion through multilateral institutions.
    • Nature of finance: Significantly, the final figure comes by adding loans and grants. Of the public finance component, loans comprise 74%, while grants make up only 20%.
    • The report does not say how much of the total loan component of $46.3 billion is concessional.
    • Non-concessional loans: From 2016 to 2018, 20% of bilateral loans, 76% of loans provided by multilateral development banks and 46% of loans provided by multilateral climate funds were non-concessional.
    • Between 2013 and 2018, the share of loans has continued to rise, while the share of grants decreased.
    • The OECD reports on climate finance have long been criticised for inflating climate finance figures.
    •  In contrast to the OECD report, Oxfam estimates that in 2017-18, out of an average of $59.5 billion of public climate finance reported by developed countries, the climate-specific net assistance ranged only between $19 and $22.5 billion per year.
    •  The 2018 Biennial Assessment of UNFCCC’s Standing Committee on Finance reports that on average, developed countries provided only $26 billion per year as climate-specific finance between 2011-2016.

    Broken commitments from the US on climate financing

    • U.S. President Joe Biden recently said that the U.S. will double its climate finance by $11.4 billion annually by 2024.
    • It is Congress that will decide on the quantum after all.
    • The U.S. also has a history of broken commitments, having promised $3 billion to the Green Climate Fund (GCF) under President Barack Obama, but delivering only $1 billion.
    • The future focus of U.S. climate finance is the mobilisation of private sector investment.
    • The bulk of the money coming in would be through private funds, directed to those projects judged “bankable” and not selected based on developing countries’ priorities and needs.

    Finance skews toward mitigation

    • Climate finance has also remained skewed towards mitigation, despite the repeated calls for maintaining a balance between adaptation and mitigation.
    • The 2016 Adaptation Gap Report of the UN Environment Programme had noted that the annual costs of adaptation in developing countries could range from $140 to $300 billion annually by 2030 and rise to $500 billion by 2050.
    • Currently available adaptation finance is significantly lower than the needs expressed in the Nationally Determined Contributions submitted by developing countries.

    Conclusion

    Delivering on climate finance is fundamental to trust in the multilateral process. Regrettably, while developing countries will continue to pressure developed countries to live up to their promises, the history of climate negotiations is not in their favour.

  • Kunming Declaration on Biodiversity Conservation

    The Kunming Declaration was adopted by over 100 countries at the first part of the ongoing virtual 15th meeting of the Conference of the Parties to the United Nations Convention on Biological Diversity.

    Kunming Declaration

    • It calls upon the parties to “mainstream” biodiversity protection in decision-making and recognise the importance of conservation in protecting human health.
    • The theme of the declaration is Ecological Civilization: Building a Shared Future for All Life on Earth.
    • By adopting this, the nations have committed themselves to support the development, adoption and implementation of an effective post-2020 implementation plan for the Cartagena Protocol on biosafety.
    • Signatory nations will ensure that the post-pandemic recovery policies, programs and plans contribute to the conservation and sustainable use of biodiversity.

    About Convention on Biological Diversity (CBD)

    • The CBD (wef 1993) known informally as the Biodiversity Convention, is a multilateral treaty.
    • The convention has three main goals:
    1. the conservation of biodiversity
    2. the sustainable use of its components
    3. the fair and equitable sharing of benefits arising from genetic resources
    • Its objective is to develop national strategies for the conservation and sustainable use of biological diversity, and it is often seen as the key document regarding sustainable development.
    • It has two supplementary agreements, the Cartagena Protocol and Nagoya Protocol.

    (1) Cartagena Protocol

    • It is an international treaty governing the movements of living modified organisms (LMOs) resulting from modern biotechnology from one country to another.

    (2) Nagoya Protocol

    • It deals with Access to Genetic Resources and the Fair and Equitable Sharing of Benefits Arising from their Utilization (ABS).
