  • Assistance to States during Natural Disasters: How It Works

    Central Idea

    • In the wake of natural disasters, states often request assistance from the central government.
    • Himachal Pradesh CM recently requested for a special disaster relief package and urged the designation of the calamity as a ‘national disaster.’

    Natural Disaster Mitigation in States

    • Legal Framework: The 2005 Disaster Management Act provides the legal framework for addressing disasters, whether natural or man-made.
    • Defining disaster: It defines a “disaster” as an event causing substantial loss of life, human suffering, property damage, or environmental degradation beyond the community’s coping capacity.
    • National Disaster Management Authority (NDMA): The Act established the NDMA, headed by the Prime Minister, and State Disaster Management Authorities (SDMAs) led by Chief Ministers. These bodies, along with district-level authorities, form an integrated disaster management setup in India.
    • National Disaster Response Force (NDRF): The Act led to the creation of the NDRF, comprising several battalions or teams responsible for on-ground relief and rescue operations in various states.

    Understanding the National Disaster Relief Fund (NDRF)

    • Mention in the Act: The NDRF is referenced in the 2005 Disaster Management Act and plays a crucial role in providing disaster relief.
    • State Disaster Relief Funds (SDRFs): States have their own SDRFs, which are the primary funds available for responding to notified disasters. The Central Government contributes 75% to SDRFs in general states and 90% in northeastern and Himalayan states.
    • Utilization of SDRFs: SDRFs are allocated for immediate relief efforts following notified calamities, including cyclones, droughts, earthquakes, fires, floods, tsunamis, and more.
    • Central Assistance: In the event of a severe calamity where state SDRF funds are insufficient, additional central assistance can be provided by the National Disaster Response Fund (NDRF).

    Who determines a Severe Calamity?

    • Procedure: States follow a specific procedure to classify a calamity as “severe.” This involves submitting a memorandum detailing sector-wise damage and fund requirements. An inter-ministerial central team assesses the damage on-site.
    • Committee Approval: Specific committees review these assessments and submit reports. A High-Level Committee must approve the immediate relief amount to be released from the NDRF.
    • Criteria: The classification of a calamity as “severe” considers factors such as intensity, magnitude, assistance needs, and more.

    Additional Funds for Disaster Mitigation

    • Funds Allocation: Funds for NDRF and SDRFs, allocated for preparedness, mitigation, and reconstruction, are part of budgetary allocations.
    • Financing mechanism: The 15th Finance Commission introduced a new methodology for state-wise allocations, considering factors like past expenditure, risk exposure, hazard, and vulnerability.
    • Utilization: NDRF and SDRF funds are released in two equal instalments, typically with requirements like Utilization Certificates. However, in urgent situations, these requirements can be waived.
    • State Disaster Mitigation Fund (SDMF): This fund supports activities such as forest restoration and public awareness. It received an allocation of Rs 32,030 crore from the 15th Finance Commission.
    • National Disaster Mitigation Fund (NDMF): The NDMF, amounting to Rs 13,693 crore, is dedicated to national disaster mitigation efforts.

  • Deadly Earthquake strikes Morocco

    morocco earthquake

    Central Idea

    • A devastating earthquake struck Morocco, resulting in significant casualties and damage.

    Details of the Moroccan Earthquake

    • Shallow Epicenter: The quake’s epicentre was near the town of Ighil, approximately 70 km southwest of Marrakech. It was considered fairly shallow, with varying depth estimates.
    • Higher Energy: Shallow earthquakes are typically more dangerous as they carry more energy, making them more destructive compared to deeper quakes.

    Major Causes

    • Tectonic Convergence: The earthquake resulted from the northward convergence of the African plate with the Eurasian plate along a complex plate boundary.
    • Faulting: The USGS attributed the quake to oblique-reverse faulting at a shallow depth within the Moroccan High Atlas Mountain range.
    • Fault Classification: Oblique-slip faults exhibit characteristics of both dip-slip and strike-slip faults, occurring in areas of compression where tectonic plates converge.

    Why discuss this?

    • Low Seismicity: Earthquakes are uncommon in North Africa, with low seismicity rates along the northern margin of the continent.
    • Historic Strength: This earthquake was the strongest ever recorded in the mountainous region, catching Morocco unprepared for such an event.
    • Construction Vulnerabilities: Many Moroccan buildings, especially in rural areas and older cities, are not constructed to withstand strong tremors.

    What is an Earthquake?

    • An earthquake is an intense shaking of the ground caused by movement under the earth’s surface.
    • It happens when two blocks of the earth suddenly slip past one another.
    • This releases stored-up ‘elastic strain’ energy in the form of seismic waves, which spreads through the earth and cause the shaking of the ground.

    morocco earthquake

    What exactly causes Earthquakes?

    • As we know, the earth’s outermost surface, crust, is fragmented into tectonic plates.
    • The edges of the plates are called plate boundaries, which are made up of faults.
    • The tectonic plates constantly move at a slow pace, sliding past one another and bumping into each other.
    • As the edges of the plates are quite rough, they get stuck with one another while the rest of the plate keeps moving.
    • Earthquake occurs when the plate has moved far enough and the edges unstick on one of the faults.
    • The location below the earth’s surface where the earthquake starts are called the hypocenter, and the location directly above it on the surface of the earth is called the epicentre.

  • Redouble efforts to reduce disaster risks

    What’s the news?

    • In 2023, the rise in disasters is not an anomaly; it’s a disturbing trend. Headlines have been dominated by a relentless wave of bad news: severe flooding in China, devastating wildfires in Europe and Hawaii, and July marking the hottest month ever recorded.

    Central idea

    • SDG: The Sustainable Development Goals (SDGs) continue to serve as our most comprehensive blueprint for achieving peace and prosperity.
    • Paris Agreement: Additionally, commitments made in the Paris Agreement to limit global warming to 1.5°C offer a clear path forward.
    • Sendai Framework: The Sendai Framework for Disaster Risk Reduction provides a global framework to reduce disaster risks, although progress in its implementation has been slow.
    • Accelerating Resilience Building: One valuable lesson we have learned from the COVID-19 pandemic is the importance of systemic disaster risk reduction, resilience, and adaptation. The crisis has not only exposed our vulnerability to risks but has also catalyzed innovative approaches, such as digital technologies and modeling. India’s proactive efforts in disaster risk reduction, including state-level disaster management plans and early warning systems, have demonstrated tangible results in reducing mortality from extreme weather events.
    • Financial Reforms for Disaster Preparedness: India’s 15th Finance Commission has introduced significant reforms for disaster risk financing, allocating substantial resources for preparedness, response, recovery, and capacity development. On the international stage, India is championing disaster resilience and sustainability through initiatives like the Coalition for Disaster Resilient Infrastructure and the deployment of its National Disaster Response Force.

    The Transformations We Need

    • Early detection system: Disaster risk reduction must be integrated at all levels of our societies. This includes how we build, invest, and live. One highly cost-effective method is the establishment of early warning systems for all, with India’s support for this endeavor being noteworthy. Such systems can significantly reduce the damage caused by impending disasters. However, it is crucial to recognize that over a third of the world’s population, primarily in the least developed countries and Small Island Developing States, lacks access to these life-saving systems.
    • The Path to a Global Multi-Risk Warning System: Our ultimate goal should be a global multi-risk warning system that covers all types of hazards, be they biological, tectonic, or technological. Improving global data capabilities is essential for better prediction and response to the risks we face. India’s leadership in knowledge sharing, joint data infrastructure, and risk analysis through its G-20 presidency deserves commendation.
    • Leaving No One Behind: We must strengthen international cooperation in disaster prevention, response, and recovery, particularly for countries in the Global South. No one should be left behind in our collective efforts to mitigate the impacts of disasters.

    Conclusion

    • The recent G-20 summit and the outcomes of the Disaster Risk Reduction Working Group offer a unique opportunity to shape a future where we are equipped to withstand disaster risk. As UN Secretary-General António Guterres wisely noted, Extreme weather events will happen. But they do not need to become deadly disasters. Together, through decisive action and unwavering commitment, we can forge a more resilient and sustainable world for generations to come.

     

  • Steps towards sustainability: Minimising digital carbon footprint

  • India’s Reforestation Legacy: A 200-Year Experiment

    reforestation

    Central Idea

    • India’s extensive history of tree planting spanning over two centuries offers valuable lessons on the consequences of various approaches to restoring forests.

    Plantations in Colonial-Era India

    • British Influence: From the mid-18th century, the East India Company and later, the British Crown, held sway over India’s affairs. During this period, British authorities directed their attention to India’s forests to meet their substantial timber needs for railway sleepers and shipbuilding.
    • Indian Forest Act of 1865: To secure a steady supply of high-yield timber trees like teak, sal, and deodar, the British enacted the Indian Forest Act of 1865. This act placed many forests under state ownership and curtailed local communities’ rights to harvest beyond grass and bamboo, even restricting cattle grazing. In response, some Indian communities resorted to burning down forests.
    • Proliferation of Teak Monocultures: Teak, well-suited to India’s hot and humid climate and prized for its durable timber, spread aggressively. This led to the transformation of pristine grasslands and open scrub forests into teak monocultures, displacing native hardwood trees like sal.
    • Introduction of Exotic Trees: Exotic species like eucalyptus, pines from Europe and North America, and acacia trees from Australia were introduced for timber, fodder, and fuel. The introduction of wattle in 1861 in the Nilgiris district of the Western Ghats marked the beginning of its invasion of this ecologically significant region.
    • Ecosystem Transformations: These introduced species, especially wattle and pine, began to displace native vegetation, impacting the ecology and livelihoods of local communities. The loss of native oak and sal trees, essential for various purposes, further exacerbated these challenges.

    Importance of Studying Past Tree Plantation Efforts

    • Regeneration Strategies: Historical strategies for natural forest regeneration have reduced carbon emissions, boosted biodiversity, and created livelihood opportunities.
    • Global Tree Cover Initiatives: Past efforts also highlight the need to differentiate between reforestation for timber production and carbon offsetting. The latter often involves planting fast-growing trees to generate timber and certify carbon credits for emission offsets.
    • Sustainable Practices: Planting trees on farms and barren lands to provide firewood and timber eased the pressure on natural forests and aided their recovery.
    • Unintended Consequences: The introduction of exotic species without thorough research can lead to invasive species and dispossess local communities of their land and resources.

    Current Restoration Efforts in India

    • Indian Commitment: India has pledged to restore around 21 million hectares of forest by 2030 under the Bonn Challenge, a global initiative aiming to restore degraded and deforested landscapes.
    • Focus on Single Species Plantations: To achieve the National Forest Policy target of a 33% forest cover, India has focused on planting single species like eucalyptus or bamboo, which grow quickly and increase tree cover.

    Impact on People and Environment

    • Concerns for Indigenous People: Afforestation in grassland ecosystems, naturally low in tree cover, may harm rural and indigenous communities. The Forest Rights Act of 2006 empowers village assemblies to manage traditional forest areas.
    • Risk of Invasive Species: The continued planting of exotic trees risks the emergence of new invasive species, similar to the wattle invasion two centuries ago.

    Case Studies

    • Community-Led Restoration: Gram Sabhas in the Gadchiroli district of Maharashtra have restored degraded forests, managing them sustainably as a source of tendu leaves used to wrap bidis (Indian tobacco).
    • Invasive Species Control: Communities in Kachchh, Gujarat, restored grasslands by removing the invasive Gando Bawal tree introduced by British foresters in the late 19th century.

    Future Considerations

    • Holistic Approach: Policies should encourage both natural forest regeneration and plantations for timber and fuel while assessing their impact on people and ecosystems.
    • Local Implications: Assess the impact of afforestation on forest rights, local livelihoods, biodiversity, and carbon storage. Scale up successful restoration practices by communities.
    • Reviving Ecosystems: Policymakers should prioritize the revival of ecosystems with a limited number of tree species, emphasizing environmental benefits over forest canopy extent.

    Conclusion

    • India’s historical journey in tree planting offers valuable insights into the complexities and consequences of reforestation efforts.
    • By learning from the past, India can develop more sustainable and inclusive strategies for restoring its forests, addressing the needs of both the environment and its diverse communities.

  • What is heat index and why is it important to measure?

    What’s the news?

    • In August, the coastal regions of Iran bore witness to an astonishing and potentially life-threatening event: a scorching heat index of 70 degrees Celsius (°C). Public holidays were declared on August 2 and 3 due to what was described as unprecedented heat.

    • The alarming incidents of rising heat temperatures are not isolated; Iran had already grappled with extreme heat earlier in the year when the Persian Gulf Airport recorded a heat index of 66.7°C. The dire consequences of such soaring temperatures demand our attention and action.

    What is the heat index?

    • The heat index, also known as the apparent temperature or feels-like temperature, is a measure of how hot it feels to the human body when relative humidity is factored in along with the actual air temperature.
    • In essence, it quantifies the discomfort or perceived warmth caused by the combination of high temperatures and high humidity.

    How is the heat index calculated?

    • Dr. Robert Steadman’s Formula: Dr. Robert Steadman, a professor at Colorado State University, developed a complex formula in 1979 to calculate the heat index. This formula considers various parameters, including air temperature and relative humidity.
    • Parameters in the Formula: The formula takes into account the following parameters:
      • Air temperature (in degrees Fahrenheit).
      • Relative humidity (expressed as a decimal, e.g., 50% RH becomes 0.50).
      • Coefficients specific to the formula (c1, c2, c3, c4, c5, c6, c7, c8, and c9).
    • Nonlinear Relationship: The formula is complex because it accounts for the nonlinear relationship between temperature, humidity, and how humans perceive heat.
    • Global Variations: Different countries may have their own variations of heat index calculations, but Dr. Steadman’s formula is widely recognized and used as a standard reference.

    Significance of measuring the heat index

    • Accurate Perception of Heat: The heat index provides a more accurate representation of how hot it feels to the human body compared to the actual air temperature. It factors in relative humidity, which significantly affects human comfort in hot conditions.

  • Ecocide Laws: Protecting Nature and Addressing Limitations

    ecocide

    Central Idea

    • Mexico’s ‘Maya train’ project has generated controversy due to its scale and environmental impact.
    • The project aims to connect tourists to historic Maya sites across a 1,525 km route, with a cost of $20 billion.
    • Critics have dubbed it a “megaproject of death” for its threats to the Yucatan peninsula’s environment, Indigenous communities, and cave systems, leading to accusations of ecocide and ethnocide.

    Understanding Ecocide

    • Ecocide, derived from Greek and Latin, means “killing one’s home” or “environment.”
    • It encompasses actions like port expansions damaging marine life, deforestation, illegal sand-mining, and polluting rivers.
    • Several countries, including Mexico, are considering ecocide legislation, with calls to elevate it to an international crime akin to genocide.
    • There is no universally accepted legal definition of ecocide.
    • A proposed definition states it as “unlawful or wanton acts committed with knowledge of causing substantial, severe, and either widespread or long-term environmental damage.

    Historical Context

    • Biologist Arthur Galston in 1970 linked environmental destruction with genocide during the Vietnam War’s Agent Orange use.
    • British lawyer Polly Higgins advocated for ecocide as an international crime in 2010.
    • The Rome Statute of the ICC deals with four major crimes but only holds perpetrators accountable for intentional wartime environmental damage.

    Importance of Ecocide as a Crime

    • Ecocide is a crime in 11 countries, with 27 others considering similar laws.
    • The European Parliament voted unanimously to include ecocide in law.
    • Ecocide laws provide a crucial legal instrument to protect the environment.
    • They can hold individuals in corporate leadership accountable and promote ethical investment practices.
    • These laws could offer justice to low- and middle-income countries disproportionately affected by climate change.

    Limitations and Concerns

    • Some argue that ecocide definitions are ambiguous, setting a low threshold for implicating entities.
    • The concept might unintentionally suggest it’s acceptable to destroy the environment for human benefit.
    • Proving ecocide may be challenging, especially for transnational crimes involving corporations.
    • The ICC’s limited jurisdiction, inability to hold corporate entities liable, and uneven track record in securing convictions are concerns.

    India’s Stance

    • India has recognized the legal personhood of nature in some judgments.
    • Some Indian judgments have used the term ‘ecocide,’ but it hasn’t fully materialized in law.
    • India’s legislative framework includes various environmental laws, which need consolidation and streamlining.
    • The National Green Tribunal lacks jurisdiction over certain critical environmental matters.
    • Addressing issues of liability and compensation remains a challenge, as seen in cases like the Bhopal gas disaster and CAMPA fund misuse.
