  • Scientists document Sperm Whales ‘Phonetic Alphabet’

    Why in the news?

    • A recent study has uncovered the intricate structure of their communication system, which appears to possess a “phonetic alphabet,” offering new insights into the depth of their social interactions.
      • Sperm whales, the largest toothed whales, utilize a diverse array of vocalizations to communicate, including bursts of clicking noises known as ‘codas’.

    About Sperm Whales (Physeter macrocephalus)).

    • Sperm whales, the largest toothed whales
    • It has a series of vertical creases or wrinkles on its body and a small, inconspicuous dorsal fin located near the rear of its back.
    • The sperm whale uses ‘echolocation’ to navigate and locate prey during these deep dives.
      • Prey: Sperm whales primarily feed on squid (including the giant squid) sharks and deep-sea fish.
      • Habitat: Sperm whales are found in deep oceanic waters worldwide, from the equator to the edges of the pack ice in the Arctic and Antarctic.
      • Behavior: Known for their exceptional diving capabilities, sperm whales can dive to depths of over 2,000 meters (6,560 feet) and stay submerged for up to 90 minutes. They are social animals, typically found in groups called pods’, which can contain up to twenty individuals.
    • Conservation Status: Listed as ‘VULNERABLE’ by the IUCN.
      • Threats cause: Collisions with ships, entanglement in fishing gear, and noise pollution.

    Insights from the Study:

    • Expressivity: The study, which utilized data from Project CETI demonstrated that sperm whale calls exhibit a broader range of expressivity than previously recognized, hinting at a nuanced mode of communication.
    • Social Dynamics: Like all marine mammals, sperm whales rely heavily on vocalizations as an integral aspect of their social interactions.
    • Contextual Analysis: The next phase of research aims to decipher the behavioural context surrounding sperm whale vocalizations, shedding light on their potential meanings.

    About Project CETI (Cetacean Translation Initiative)

    • Project CETI is a non-profit, interdisciplinary scientific and conservation initiative on a mission to listen to and translate the communication of sperm whales off the island of Dominica in the Eastern Caribbean.

  • Explained Climate: Heatwaves and Climate Change

    Why in the News? 

    According to the Indian Meteorological Department (IMD), heatwave conditions are affecting either the smaller regions or the larger geographical areas in India at every 26 days of the month.

    What are the Heat Waves?

    • The “World Meteorological Organization” defines a heat wave as five or more consecutive days during which the daily maximum temperature exceeds the average maximum temperature by five degrees Celsius.
    • If the maximum temperature of any place continues to be more than 45 Degree Celsius consecutively for two days, it is called a heat wave condition.

    Heatwaves in India:       

    • Regional Observations: A place with a normal temperature of 40°C in summer is not experiencing a heatwave at 42-43°C, but another location with a normal temperature of 27-28°C is in a heatwave at 35°C.
      • Heatwaves are common in northern, central, and eastern India during summer. Heatwaves are becoming more frequent, intense, and prolonged due to climate change.
      • In February 2023 (winter month for India), several regions experienced heatwaves with maximum temperatures 5 to 11 degrees higher than normal. (with a mean temperature 1.36°C higher than normal)
    • Predictions and Records: The outlook for heatwaves this year is grim, with predictions of prolonged heatwaves lasting 10 to 20 days in some areas, compared to the usual 4 to 8 days.
      • In April 2023, Odisha experienced an 18-day heatwave, the second-longest in the state’s history.
      • Gangetic West Bengal recorded the highest number of heatwave days in any month over the last 15 years. Eastern India recorded its warmest April ever.
    • Upcoming Heatwave: The India Meteorological Department (IMD) forecasted a fresh spell of heatwaves starting over northwest India.

    Impact of Heatwaves:

    • Impact on Resource Availability:
      • Water Resources: It exacerbates water scarcity by drying up of water bodies, reducing water availability for agriculture and domestic use, and increasing competition for resources. This can lead to conflicts over water, affect irrigation practices, and impact water-dependent industries.
      • Energy Resources: It increases electricity demand for cooling purposes, leading to strain on power grids and potential blackouts. This can disrupt economic activities, affect productivity, and impact vulnerable populations.
    • Impact on Health:
      • Prolonged exposure to heat can lead to Dehydration and Cardiovascular and Respiratory diseases.
      • Rapid rises in heat gain can compromise the body’s ability to regulate temperature and can result in a cascade of illnesses, including heat cramps, heat exhaustion, heatstroke, and hyperthermia.
      • Health Ministry reported 264 heat-related deaths in the first six months of 2023. NCRB reported 730 heat-related deaths in the same year.

    However, data collected and maintained by IMD and NDMA (National Disaster Management Authority) showed a sharp decline in heat-related deaths ever since state governments and district administrations began implementing heat action plans.

    Mitigation of Heatwaves:

    • Need to establish an Early Warning System: The Inter-Agency Coordination needs to alert residents on predicted high and extreme temperatures. Who will do what, when, and how is made clear to individuals and units of key departments, especially for health.
    • Increase Public Awareness and Community Outreach: Disseminating public awareness messages on how to protect against the extreme heat – wave through social media and advertisements. Additionally, the government needs to aware the general public through Television programs the Do’s and Dont’s for heat-related illnesses.

    Conclusion: Need to improve collaboration with Non-governmental organizations and Civil society organizations to improve public spaces wherever necessary, improve water delivery systems in public areas, and other innovative measures to tackle heatwave conditions.

  • On Delhi’s mounting Waste Crisis | Explained

    Why in the News? 

    On May 13, the Supreme Court stated that addressing the “horrible” issue of 3,800 metric tonnes of untreated Municipal Solid Waste (MSW) accumulating daily in the national capital requires moving beyond party politics.

    What is the status of Delhi’s SWM system?

    • Population Growth and Waste Generation:
      • According to the 2011 Census Data, New Delhi’s population was approximately 1.7 crore. However, this Population is expected to increase to around 2.32 crore.
      • This increase will lead to a significant rise in waste generation, estimated at approximately 13,000 tonnes per day (TPD), which equates to roughly 1,400 truckloads daily.
      • Presently, this daily waste generation accumulates to about 42 lakh tonnes per annum. The population is anticipated to reach 2.85 crore by 2031 due to which the waste generation could increase to 17,000 TPD.
    • Waste Collection: Around 90% of the waste generated in the city is collected by three municipal corporations:
    • Municipal Corporation of Delhi (MCD)
    • Delhi Cantonment Board
    • New Delhi Municipal Corporation
    • Waste Composition is of major types – Biodegradable Wet Waste (50-55%), Non-Biodegradable Dry Waste (around 35%), and Inert Waste (10% that does not decompose). The total collective capacity of these facilities is about 9,200 tonnes per day (TPD).

    Issue of Unprocessed Waste Disposal: 

    • The Municipal Corporation of Delhi (MCD) is disposing of 3,800 TPD of unprocessed waste in landfills.
    • Designated Landfills (Gazipur, Bhalswa, and Okhla) are filled with unprocessed wet and dry waste, leading to significant environmental issues such as methane gas emissions, leachate production, and landfill fires.
    • The landfills have accumulated a total of 2.58 crore tonnes of legacy waste, covering 200 acres of land.

    What are the challenges faced by MCD?

    • Lack of Waste Segregation at Source: Many households and commercial establishments do not segregate waste. Unprocessed mixed waste enters landfills as a result.
    • Land Availability for Waste Processing Plants: Waste processing plants require large land parcels (30-40 acres each). Securing such large tracts of land is challenging in Delhi.
    • Public Awareness and Practices: There is a lack of public awareness regarding proper waste management practices. This leads to littering and improper disposal habits. MCD’s focus shifts to clearing open points rather than processing wet waste.
    • Inadequate Waste Collection Services: Some areas suffer from irregular waste collection services. This contributes to waste buildup and increased littering.
    • Illegal Dumping: Waste is often illegally dumped in open areas and water bodies. This increases the pressure on the MCD and requires additional resources for cleanup.

    What efforts need to be made by MCD?

    • Need for a Decentralized Approach: Given the challenges of identifying large land parcels, Delhi will need to partner with its neighboring States to set up a few of these composting plants.
      • Additionally, the market for organic compost produced from wet waste lies in the neighboring States of Haryana and Uttar Pradesh.
    • Need to work on Biodegradable Wet Waste: The design capacity for wet waste processing should be 9,000 TPD. This would require at least 18 composting or biogas plants (assuming each plant has a capacity of 500 TPD).
      • Significant efforts will be needed to identify land, establish composting facilities, and ensure their proper operation to prevent biodegradable waste from reaching landfills.
    • Need to work on Non-Biodegradable Dry Waste: Approximately 2% of dry waste is recyclable and should be sent to recycling facilities. The remaining 33% of non-recyclable dry waste (plastics, paper, textile waste) can be used as RDF for power generation in waste-to-energy projects.
    • Coordination Among Stakeholders: Improved coordination between various Municipal Corporations to streamline waste collection and segregation processes by collaborating with private companies and non-governmental organizations is needed to enhance waste segregation and processing efforts.

    Conclusion: Already, Biomining Initiative was launched in 2019 by the MCD to reduce the amount of waste. The COVID-19 pandemic interrupted these efforts. Originally planned for completion by 2024, now expected to take an additional two to three years.

    About Graded Response Action Plan (GRAP)

    • The GRAP was conceived as a response to the alarming findings of a WHO study in 2014, which ranked Delhi as the most polluted city globally.
    • It is a framework designed to combat air pollution in the Delhi-NCR region.
    • The Supreme Court (M. C. Mehta vs. Union of India Case, 2016) approved GRAP after multiple expert consultations.
    • First GRAP was notified in January 2017 by the Ministry of Environment, Forest and Climate Change.

    Implementation of GRAP:

    • The Commission for Air Quality Management in NCR & Adjoining Areas (CAQM) took over the responsibility of implementing GRAP in 2021.
    • Before 2021, the SC appointed Environment Pollution (Prevention and Control) Authority (EPCA) would instruct states to enforce GRAP measures.
    • The CAQM recommendations depend on the Air Quality Index (AQI) and meteorological predictions provided by the Indian Institute of Tropical Meteorology (IITM) and the India Meteorological Department (IMD).

    Revised measures to implement:

    Air Quality Stage AQI Range Measures to be implemented
    Stage I (Poor) 201-300 Enforce NGT/Supreme Court’s order on over-aged diesel/petrol vehicles.
    Stage II (Very Poor) 301-400 Implement rigorous actions to combat air pollution at identified hotspots.
    Stage III (Severe) 401-450 Impose strict restrictions on BS III petrol and BS IV diesel vehicles. Suspend physical classes in schools for primary grade children up to Class 5 in certain areas.

    Why in the News?

    Despite its ecological importance, rampant harvesting of Semal Trees for bonfires poses a grave threat to their existence, undermining biodiversity and cultural heritage alike.

    About Semal/ Silk Cotton Trees

    • The Semal tree, scientifically known as Bombax ceiba, is a deciduous tropical tree.
    • It is native to India, South-East Asia, and Northern Australia.
    • It can grow up to 60 meters tall. It has a distinctive straight trunk, often with spiky thorns, and a wide, spreading canopy.
    • It produces vivid red flowers that are large and attractive, making it quite conspicuous when in bloom.
    • The fruit of the Semal tree is a capsule that contains several seeds surrounded by a fibrous, cotton-like substance which is wind-dispersed.

    Commercial Uses

    • The fibers extracted from the fruit, known as kapok, are used for stuffing pillows, mattresses, and life jackets due to their buoyancy and insulating properties.
    • The wood is soft and is often used for making paper, while in rural areas, it is used as fuelwood and for making cheap furniture.

    Ecological Significance

    • Members of tribal communities consume the tree’s reddish root for food during the monsoons.
    • Larvae of the moth Bucculatrix crateracma feed on its leaves.
    • The golden-crowned sparrow weaves the lining of its nests with white cotton from its seeds.

    Felling of a Semal Tree: Which laws are violated?

    1. Rajasthan Forest Act 1953: This act prohibits various activities in reserved forests without prior permission. Specifically, it bars any unauthorized person from felling, uprooting, damaging, or otherwise harming trees. Violating these prohibitions can lead to penalties including imprisonment, fines, or both, depending on the severity of the offence. Semal tree is not recorded in the state’s list of ‘rare, threatened, and endangered’ species. (Trees on this list enjoy priority conservation efforts.) (Indian Kanoon)​
    2. Forest (Conservation) Act 1980: This act is more comprehensive at the national level and was enacted to provide for the conservation of forests and to regulate deforestation. It requires that any non-forest use of forest land must have prior approval from the Central Government. This includes clearances for felling trees, which are only granted under specific conditions that ensure the conservation and sustainable use of forest resources.​ (UNEPLawEnvAssistantPlat)​

  • 19th Session of the United Nations Forum on Forests (UNFF19) in New York

    Why in the news? 

    Recently, during the 19th Session (10th May 2024) of the United Nations Forum on Forests (UNFF19) in New York, a significant report titled “International Forest Governance” was published.

    About International Forest Governance: 

    • The report “Critical Review of Trends, Drawbacks, and New Approaches” authored by the Science-Policy Programme (SciPol) of the International Union of Forest Research Organizations (IUFRO) was released.
    • It marked the first global synthesis on international forest governance in 14 years.

    The report exposes the rising trend of ‘Climatization’ of forests:

    About Climatization of forests: 

    • Shift in Emphasis: The trend involves a notable shift in focus towards valuing forests primarily as carbon sinks, rather than recognizing their essential ecological and social functions.
    • Carbon Sequestration Priority: Political and financial orientations have increasingly prioritized carbon sequestration in forests as a means to address climate change issues. This emphasis often leads to the overshadowing of other aspects of forest management.
    • Neglect of Long-Term Sustainability: The emphasis on carbon sequestration may result in neglecting the long-term sustainability of forests. Forest management strategies that prioritize carbon storage may not necessarily align with broader ecological and social sustainability goals.

    Risks and their impacts:

    • Ongoing Crises: Despite efforts to reduce deforestation, significant challenges persist, including climate change, biodiversity loss, and socio-economic inequalities. These crises pose substantial threats to global sustainability and well-being.
    • Commodification Risks: The commodification of forests for carbon capture introduces risks that may exacerbate existing inequalities and hinder effective forest management practices.

    Market-based Versus Non-market Approaches:

    • Market-Based Solutions: There has been significant traction in market-based solutions such as forest carbon trading and zero-deforestation supply chains. These approaches aim to incentivize sustainable forest management practices through economic mechanisms.
    • Exacerbation of Inequities: Despite their popularity, market-based solutions may exacerbate existing inequities within forest governance systems. Certain stakeholders or regions may benefit disproportionately, while others may be marginalized or disadvantaged.
    • Non-market mechanisms: As an alternative, non-market mechanisms, including state regulation and community-led initiatives, are suggested to offer more just and effective pathways for forest governance.

    Policy recommendations as per the Report:

    • Holistic Valuation of Forests: Policymakers should reevaluate forests beyond their role as carbon sinks, recognizing their multifaceted ecological, social, and economic values.
    • Equitable Governance: Policymakers should prioritize inclusive decision-making processes that ensure the voices of marginalized groups, such as indigenous and local communities, are heard and respected.
    • Protection of Rights and Livelihoods: Policies should prioritize the protection of the rights and livelihoods of resource-dependent communities.

    Way Forward: 

    • Integrated Forest Management: Governments and international organizations should adopt integrated approaches to forest management that recognize and balance the ecological, social, and economic values of forests.
    • Strengthening Governance Structures: Policymakers should work to strengthen governance structures at local, national, and international levels to ensure more equitable decision-making processes.

  • Artificial Rain through Cloud Seeding

    Why in the news?

    The Uttarakhand government faced scrutiny from the Supreme Court following Forest fires that claimed lives in the state.

    • Justices highlighted the inefficacy of relying solely on cloud-seeding or rain gods to address the crisis.

    Case Study: Experimenting Artificial Rain in India

    • A recent study published in the Bulletin of the American Meteorological Society (BAMS) highlighted the success of a cloud seeding trial in Maharashtra’s Solapur region, which resulted in an 18% increase in rainfall compared to normal patterns.
    • Scientists from the Indian Institute of Tropical Meteorology in Pune and other institutes conducted this study.
    • The experiment targeted warm convective clouds with a height above zero degrees Celsius, releasing calcium chloride particles to stimulate rainfall.
    • Spanning from 2017 to 2019, the experiment analyzed 276 clouds using advanced tools like automatic rain gauges, radars, radiometers, and aircraft.
    • Glaciogenic seeding, attempted in clouds containing both ice and water, did not significantly impact rainfall at the seeding location, according to the study’s findings.

    About Cloud-Seeding

    • Cloud seeding is a weather modification technique aimed at altering precipitation patterns by dispersing substances into clouds to stimulate rainfall or snowfall.
    • It is used to mitigate hail, disperse fog, and either induce precipitation or prevent it from occurring in subsequent days.
    • It involves the dispersal of substances like silver iodide, potassium iodide, dry ice, and hygroscopic materials such as table salt into the atmosphere.
    • Techniques include:
    1. Static seeding: promotes ice particle formation in supercooled clouds, and
    2. Dynamic seeding: enhances convective cloud development through the release of latent heat.
    • Dispersion methods range from aircraft and ground-based generators to newer approaches like drones delivering electric charges or infrared laser pulses.

    Limitations: Impact on Environment and Health

    • Concerns persist regarding the potential accumulation of seeding agents in sensitive ecosystems, although detailed studies have shown negligible impacts.
    • The chemicals used, such as silver iodide, may potentially damage the environment and cause health issues like iodine poisoning in high concentrations
