  • ‘climate smart’ agriculture

    Context

    In the backdrop of the 2070 carbon neutrality target set by India at the CoP26 in Glasgow, the Union Budget for 2022-23 has listed “climate action” and “energy transition” as one of the four priorities for the Amrit Kaal.

    Climate related announcement in Budget 2022-23

    • An additional allocation of Rs 19,500 crore for solar PV modules has been made.
    • The finance minister also talked of co-firing of 5-7 per cent of biomass pellets in thermal power plants, “sovereign green bonds” and a “battery-swapping policy”.
    • These are positive steps towards making the energy and transport sectors less polluting.

    How agriculture impact environement

    • Agriculture contributes 73 per cent of the country’s methane emissions. 
    • Third largest emitter: India has kept away from the recent EU-US pledge to slash methane emissions by 30 per cent by 2030, despite the country being the world’s third largest emitter of methane.
    • As per the national GHG inventory, the agriculture sector emits 408 MMT of carbon-dioxide equivalent and rice cultivation is the third highest source (17.5 per cent) of GHG emissions in Indian agriculture after enteric fermentation (54.6 per cent) and fertiliser use (19 per cent).
    • Paddy fields are anthropogenic sources of atmospheric nitrous oxide and methane, which have been reckoned as 273 and 80-83 times more powerful than carbon dioxide in driving temperature increase in 20 years’ (Sixth Assessment Report IPCC 2021).
    • Moreover, paddy fields require about 4,000 cubic metres of water per tonne of rice for irrigation.
    •  There is scientific evidence that intermittent flooding reduces water and methane emissions but increases nitrous oxide emissions.
    • Thus, lowering of methane emissions through controlled irrigation does not necessarily mean net low emissions. 
    • Role of subsidies and procurement policies: The environmental damage caused by agriculture is largely a result of the various kinds of subsidies — on urea, canal irrigation and power for irrigation — as well as the minimum support prices (MSP) and procurement policies concentrated on a few states and largely on two crops, rice, and wheat.

    Excess rice and wheat stock

    • As of January 1, the stocks of wheat and rice in the country’s central pool were four times higher than the buffer stocking requirement.
    • Rice stocks with the Food Corporation of India (FCI) are seven times the buffer norms for rice.
    • The financial value of these excessive grain stocks is Rs 2.14 lakh crore, of which Rs 1.66 lakh crore is because of excess rice stocks — as per the economic cost of rice and wheat given by the FCI.
    • All this does not just reflect inefficient use of scarce capital, the amount of greenhouse gases (GHG) embedded in these stocks is also large.

    Way forward

    • Carbon tax: According to the IMF, the world needs a carbon tax of $ 75 per tonne by 2030 to reduce emissions to a level consistent with a 2 degree Celsius warming target.
    • India does not have an explicit carbon-price yet, but many countries have begun to implement carbon pricing.
    • Revisiting policies: The Economic Survey 2021-22 points out that the country is over-exploiting its ground water resource (see map), particularly in the northwest and some parts of south India.
    • This calls for revisiting policies to subsidise power and fertilisers, MSP and procurement and reorient them towards minimising GHG emissions.
    • Farmer groups and the private sector can be mobilised to develop carbon markets in agriculture, both at the national and international levels, which can reward farmers in cash for switching from carbon-intensive crops to lower GHG emissions.

    Consider the question “Elaborate on the impact of agriculture on the environment. Suggest the changes needed in Indian agriculture policies to reduce the impact.”

    Conclusion

    Such a move towards “net-zero” agriculture will give India a “climate smart” agriculture in Amrit Kaal. And, if we can protect productivity levels with a low-carbon footprint, it will help India to access global markets too.

  • Australia lists Koalas as Endangered Species

    Once found in abundance, Australia’s much-loved koalas have now been officially classified as ‘endangered’ after widespread bushfires, drought and land clearing destroyed much of their eucalyptus-rich habitat.

    Koalas

    IUCN Status: Vulnerable

    • According to fossil records, Koala species have inhabited parts of Australia for at least 25 million years, a WWF report states.
    • But today, only one species remains — the Phascolarctos cinereus.
    • They are found in the wild in the southeast and eastern sides of Australia — in coastal Queensland, New South Wales, South Australia and Victoria.

    Threats to Koalas

    • Since Europeans first settled in the region, the Koala population has faced widespread habitat loss, particularly due to agriculture and the construction of urban settlements.
    • They survive on a strict diet of up to a kilogram of eucalyptus leaves every day.
    • Due to the low nutritional value of these leaves, koalas tend to sleep for extended periods, often up to 18 hours a day, to conserve energy.

  • How to expand India’s forest cover

    Context

    The recently released India State of Forest Report (ISFR) 2021 shows the total forest and tree cover in India is 80.9 million hectares, which is 24.62 per cent of the geographical area of the country.

    Definition of forest in India

    • India’s definition of forest cover is in sync with that of the Kyoto Protocol.
    • A “forest” has a minimum area of 0.05 to 1 ha (India has 1.0 ha minimum), with the tree crown cover percentage being more than 10 to 30 per cent (India has 10 per cent) and with trees having the potential to reach a minimum height of 2 to 5 m at maturity in situ (in India, it’s 2 m).
    • The definition thus arrived at by India assesses forests as all lands, more than 1 hectare in area, with a tree canopy density of more than 10 per cent irrespective of ownership and legal status.
    • Such lands may not necessarily be a recorded forest area.
    • It also includes orchards, bamboo, palm etc.

    Assessment of forest cover

    • The assessment of forest cover is done based on the interpretation of satellite data, which basically identifies umbrella-shaped canopies from the sky.
    • The forest cover is also estimated from field inventory data, which corroborates the figures of forest cover obtained from the satellite-based interpretation.
    • The environment ministry is even considering providing forest cover maps through the Web Map Service to make the analyses of researchers and agencies easier.
    • Importance of plantations: The importance of plantations needs to be understood.
    • For example, cashew plantations, which mainly grow along the coast, serve as the first line of defence against cyclones, which are hitting with greater frequency and ferocity.
    • Mixed plantations, especially of native species, meet all the ecological functions of natural forests.
    • A lot of wildlife inhabits these plantations.
    • While we do not advocate equating natural forests with plantations, let us recognise their ecological functions.

    Afforestation efforts

    • India is on track to achieve its national commitment to land degradation neutrality.
    • India is working towards restoring 26 million hectares of degraded land by 2030.
    • Our afforestation efforts are also aligned with our wildlife conservation efforts.
    • Project Tiger was launched in 1973.
    • From nine tiger reserves initially, we now have 51 tiger reserves.
    • These are the cornerstones of wildlife conservation and preserve natural ecosystems which support ecological processes responsible for providing various goods and services that are vital for human well-being.

    Way forward

    • Notwithstanding these gains, the goal of 33 per cent area under forest and tree cover as per the National Forest Policy, 1988, remains to be achieved.
    • Focus on TOF: The balance of 9 per cent can be achieved through taking up plantation/afforestation outside the forests and restocking/plantation in degraded and scrub forests.
    • According to the ISFR 2021, the Trees outside forest (TOF) extent comprises 36.18 per cent of the total forest and tree cover of the country.
    • Given this fact, the draft NFP 2021 has focused on the promotion of TOF by including it among its objectives.
    • NFP 2021: Given this fact, the draft NFP 2021 has focused on the promotion of TOF by including it among its objectives.
    • The provisions in draft NFP 2021 include substantially increasing the tree cover outside forests by incentivising and promoting agro-forestry and farm forestry; managing and expanding green spaces in urban and peri-urban areas to enhance citizens’ well-being; plantation of trees outside forests in partnership with local communities, land-owning agencies, and private enterprises; creation, sustainable management and promotion of urban forests; afforestation/reforestation in public-private partnership (PPP) mode; promotion of urban forests.

    Conclusion

    It is with this holistic approach that India is moving towards restoring the ecological balance of the planet and ensuring sustainable development.

  • Species in news: White-Cheeked Macaque

    In an important discovery, scientists have recorded presence of White-Cheeked Macaque (Macaca leucogenys) from central Arunachal Pradesh.

    White-Cheeked Macaque

    • White- Cheeked Macaques are distinct from other macaques found in the region by displaying white cheeks, long and thick hairs on the neck area, and a longer tail.
    • The species was discovered in 2015 by a group of Chinese scientists from the Modog region in southeastern Tibet.
    • This discovery was considered a significant breakthrough as far as primates are concerned.

    Existence in India

    • From India, the species has not been sighted or reported after a single incidence of photographic capture from Anjaw district, Arunachal Pradesh in 2015.
    • The number of these mammals reported from India stands at 434.
    • The significance of the discovery is that it marks a new addition to mammals of India.

    Protection status

    • It has NOT been yet included in the Wildlife (Protection) Act, 1972 of India.
    • The potential threat to all species of macaques in the landscape is due to hunting by locals for consumption and habitat degradation due to urbanization and infrastructure development.

  • What is Havana Syndrome?

    A recent US intelligence report says that ‘Havana Syndrome’ —a collection of symptoms and related brain injuries, reported by some US officials could be caused by pulsed electromagnetic energy or close-range ultrasound.

    What is Havana Syndrome?

    • ‘Havana Syndrome’ is a colloquial name given to a set of symptoms such as dizziness, hearing loss, headaches, vertigo, nausea, memory loss and possible brain injuries.
    • It was first reported by 16 American Embassy staff and their family members in Havana, Cuba, in 2016-17.
    • There have been other instances of the phenomenon, which has mostly impacted US officials.

    What did the latest investigation find?

    • Such cases have been caused by pulsed electromagnetic energy in the radio frequency.
    • The results of the investigation did not point to who may have been behind the phenomenon, nor commented on their motivations.
    • A partially redacted report summary finds that the symptoms of AHI are “genuine and compelling.”

    What can be the other reasons?

    • Psychosocial factors alone do not explain the core characteristics, the report finds, although they may cause other incidents or contribute to long-term effects.
    • These other incidents could occur via hyper-vigilance or reactions to stress especially among individuals who are security-oriented.

  • [pib] Definition of Forest in India

    The Union Ministry of Environment, Forest & Climate Change has informed about the criteria used to define forest in India.

    Defining Forests universally

    • As per the Conference of Parties (CoP) 9-Kyoto Protocol, the forest can be defined by any country depending upon the capacities and capabilities of the country.
    • Forest- Forest is defined structurally on the basis of
    1. Crown cover percentage: Tree crown cover- 10 to 30% (India 10%)
    2. Minimum area of stand: area between 0.05 and 1 hectare (India 1.0 hectare) and
    3. Minimum height of trees: Potential to reach a minimum height at maturity in situ of 2 to 5 m (India 2m)

    India’s definition of Forests

    The definition of forest cover has clearly been defined in all the India State of Forest Report (ISFR) and in all the International communications of India.

    • The forest cover is defined as ‘all land, more than one hectare in area, with a tree canopy density of more than 10 percent irrespective of ownership and legal status.
    • Such land may not necessarily be a recorded forest area. It also includes orchards, bamboo and palm’.

    Classification of forest cover

    In ISFR 2021 recently published has divided the forest cover as:

    1. Inside Recorded Forest Area: These are basically natural forests and plantations of Forest Department.
    2. Outside Recorded Forest Area: These cover mango orchards, coconut plantations, block plantations of agroforestry.

    Back2Basics: Forest Classification in India

    The Forest Survey of India (FSI) classifies forest cover in 4 classes.

    • Very Dense forest: All lands with tree cover (including mangrove cover) of canopy density of 70% and above.
    • Moderately dense forest: All lands with tree cover (including mangrove cover) of canopy density between 40% and 70%.
    • Open forests: All lands with tree cover (including mangrove cover) of canopy density between 10% and 40%.
    • Scrubs: All forest lands with poor tree growth mainly of small or stunted trees having canopy density less than 10%.

  • Places in news: Godavari Estuary in Coringa Wildlife Sanctuary (CWS)

    Godavari Estuary in Coringa Wildlife Sanctuary (CWS) is facing due ignorance despite meeting all nine criteria of Ramsar Convention.

    Godavari Estuary

    • The estuary, including 235.70 sq. km Coringa Wildlife Sanctuary (CWS), is one of the rarest eco-regions on the earth.
    • It is also home to India’s second-largest mangrove cover after the Sundarbans.
    • The CWS is inhabited by 115 endangered fishing cats (Prionailurus viverrinus), Olive Ridley turtles, Indian smooth-coated otter, and saltwater crocodiles.

    What are the nine criteria laid out by Ramsar Convention?

    • Criterion 1: “it contains a representative, rare, or unique example of a natural or near-natural wetland type found within the appropriate biogeographic region.”
    • Criterion 2: “it supports vulnerable, endangered, or critically endangered species or threatened ecological communities.”
    • Criterion 3: “it supports populations of plant and/or animal species important for maintaining the biological diversity of a particular biogeographic region.”
    • Criterion 4: “it supports plant and/or animal species at a critical stage in their life cycles, or provides refuge during adverse conditions.”
    • Criterion 5: “it regularly supports 20,000 or more waterbirds.”
    • Criterion 6: “it regularly supports 1% of the individuals in a population of one species or subspecies of waterbird.”
    • Criterion 7: “it supports a significant proportion of indigenous fish subspecies, species or families, life-history stages, species interactions and/or populations that are representative of wetland benefits and/or values and thereby contributes to global biological diversity.”
    • Criterion 8: “it is an important source of food for fishes, spawning ground, nursery and/or migration path on which fish stocks, either within the wetland or elsewhere, depend.”
    • Criterion 9: “it regularly supports 1% of the individuals in a population of one species or subspecies of wetland-dependent non-avian animal species.”

    Back2Basics: Ramsar Convention

    • The Convention on Wetlands of International Importance (better known as the Ramsar Convention) is an international agreement promoting the conservation and wise use of wetlands.
    • It is the only global treaty to focus on a single ecosystem.
    • The convention was adopted in the Iranian city of Ramsar in 1971 and came into force in 1975.
    • Traditionally viewed as a wasteland or breeding ground of disease, wetlands actually provide fresh water and food and serve as nature’s shock absorber.
    • Wetlands, critical for biodiversity, are disappearing rapidly, with recent estimates showing that 64% or more of the world’s wetlands have vanished since 1900.
    • Major changes in land use for agriculture and grazing, water diversion for dams and canals, and infrastructure development are considered to be some of the main causes of loss and degradation of wetlands.
