  • The blurry lines between wildlife ‘capture’ and ‘rescue’  

    Why in the news? 

    The human-animal conflict in India is a significant issue, with several lives lost and property damage due to the increasing interactions between humans and wildlife

    Difference between between wildlife ‘capture’ and ‘rescue’

    • Capture:  It refers to the act of taking wild animals into custody, often due to conflicts with humans, such as when an animal poses a threat to human safety or property. This may involve trapping, sedating, or physically restraining the animal. The primary goal of capture is to ensure human safety and prevent further damage. Captured animals may be relocated, rehabilitated, or, in some cases, euthanized, depending on the situation and the animal’s condition.
    • Rescue:  It refers to the act of providing assistance to wild animals in distress, such as those injured, orphaned, or trapped in a dangerous situation. The primary goal of rescue is to help the animal recover and, if possible, return it to the wild. Rescue efforts may involve medical treatment, rehabilitation, and release back into the wild.

    Blurred lines between “rescue” and “capture”

    • Guidelines vs. Reality: Despite government guidelines discouraging capture without considering preventative measures, in practice, animals are often captured hastily rather than adopting non-invasive approaches.
    • Case of Elephant “Rescue”: An elephant was captured under the pretext of rescue from a coffee plantation but was subsequently released 200 km away in an unfamiliar landscape, leading to further complications and ultimately its death.
    • Unintended Consequences: The attempt to “rescue” the elephant resulted in its straying into a neighboring state, highlighting the unintended consequences and potential risks associated with such actions.
    • Case of Leopard “Rescue”: Similarly, a leopard was “rescued” after being sighted in an agricultural field, but it died shortly after for unknown reasons, raising questions about the efficacy and ethics of such operations.

    Issues related to rescue of snakes

    • High Frequency of Interactions: Interactions with snakes are more frequent than with other wild animals, resulting in higher incidences of misguided rescue attempts.
    • Failure to Distinguish Between Actions: There’s a lack of distinction between capture, removal, and rescue when managing conflicts with snakes, leading to poor handling and unnecessary removal from habitats under the guise of rescue operations.
    • Issues with Relocation: Relocated snakes have poor survival prospects and relocation doesn’t effectively resolve conflict, potentially increasing future conflict occurrences.
    • Harmful Effects of “Rescue” Operations: Such operations can cause physical trauma, injuries, and stress to animals, reducing their post-release survival chances.

    Suggestive measures

    • Education and Training: Provide comprehensive training to wildlife rescuers on species-specific rescue techniques and emphasize the importance of non-invasive approaches.
    •  Habitat Restoration: Focus on habitat conservation and restoration to reduce human-snake conflicts and provide natural habitats for snakes.
    • Research and Monitoring: Conduct research to understand snake behavior and ecology better, enabling more informed rescue and relocation decisions.
    • Collaboration: Foster collaboration between wildlife authorities, conservation organizations, and local communities to develop effective strategies for managing human-snake conflicts sustainably.

    Conclusion 

    Enhanced training, habitat restoration, research, and collaboration are vital for navigating the blurry lines between wildlife “capture” and “rescue,” ensuring humane and effective management of human-animal conflicts in India.

  • The need to curb Black Carbon Emissions | Explained

    Why in the News? 

    According to the Ministry of New and Renewable Energy, India had installed a renewable energy capacity of over 180 GW by 2023 and is expected to meet its target of 500 GW by 2030.

    Context

    At the COP26 climate talks in Glasgow in November 2021, India pledged to achieve net-zero emissions by 2070, positioning itself as a frontrunner in the race to carbon neutrality.

    Why is black carbon relevant?

    • Cause of global warming : lack carbon is the dark, sooty material emitted alongside other pollutants when biomass and fossil fuels are not fully combusted. It contributes to global warming
    • Poses severe risks: Studies have found a direct link between exposure to black carbon and a higher risk of heart disease, birth complications, and premature death. Most black carbon emissions in India arise from burning biomass, such as cow dung or straw, in traditional cookstoves.

    Status of Black Carbon

    • According to a 2016 study, the residential sector contributes 47% of India’s total black carbon emissions. Industries contribute a further 22%, diesel vehicles 17%, open burning 12%, and other sources 2%.
    • Decarbonisation efforts in the industry and transport sectors in the past decade have yielded reductions in black carbon emissions, but the residential sector remains a challenge.

    Has PMUY helped?

    • Objective of PMUY: The primary objective of PMUY, launched by the Government of India in May 2016, is to provide free liquefied petroleum gas (LPG) connections to households below the poverty line. This aims to offer a cleaner cooking fuel alternative to traditional biomass fuels, particularly in rural and poor households, thereby reducing their dependence on such polluting fuels.
    • Infrastructure Establishment: PMUY has established necessary infrastructure to support LPG connections, including provision of free gas stoves, deposits for LPG cylinders, and a distribution network. This infrastructure is crucial for enabling the adoption of clean cooking practices.
    • Role in Reducing Black Carbon Emissions: By providing cleaner LPG alternatives to traditional biomass fuels, PMUY has played a vital role in reducing black carbon emissions. This initiative contributes to mitigating environmental pollution and improving air quality, particularly in households previously reliant on polluting cooking fuels.

    Challenges and Shortcomings:

    Despite its objectives and infrastructure, challenges persist in fully transitioning beneficiaries to LPG usage.

    • High gap between LPG connections and actual adoption:  In 2022-2023, a significant portion of PMUY beneficiaries, representing 25%, continued to rely entirely on traditional biomass fuels for cooking. This indicates a gap between the provision of LPG connections and actual adoption of clean cooking practices.
    • Low Refill Rates and Energy Consumption: RTI data revealed that a substantial number of PMUY beneficiaries availed either zero or only one LPG refill, indicating low usage of LPG cylinders. Additionally, the average PMUY beneficiary household consumes significantly fewer LPG cylinders per year compared to non-PMUY households. This suggests that traditional fuels still meet a significant portion of energy needs in PMUY beneficiary households.
    • Health Impacts: The continued reliance on traditional fuels has detrimental health effects, particularly on women and children who are disproportionately affected by indoor air pollution. This leads to various health issues and premature deaths, highlighting the urgent need for increased adoption of clean cooking practices.
    • Affordability: Despite subsidies and recent increases(subsidy to ₹300 from ₹200. ), the cost of LPG cylinders remains high for many PMUY beneficiaries. This affordability challenge discourages households from consistently purchasing and using LPG cylinders, especially when traditional biomass alternatives are perceived as “free.”
    • Temporary Subsidies: While the government has announced temporary price reductions to address affordability concerns, the sustainability of such subsidies remains uncertain. Temporary measures may not provide long-term solutions to ensure consistent access to clean cooking fuel for beneficiaries.
    • Low Refill Rates: Low refill rates persist among PMUY beneficiaries, indicating a gap between initial LPG connections provided and sustained usage. This issue stems from both affordability concerns and challenges in availability and distribution of LPG cylinders.
    • Last-Mile Connectivity: Remote rural areas face challenges in accessing LPG due to inadequate last-mile connectivity in the distribution network. This results in continued reliance on traditional biomass fuels, perpetuating indoor air pollution and health risks.
    • Alternative Fuel Solutions: Local production of coal-bed methane (CBM) gas presents a potential solution to address the lack of last-mile connectivity and provide cleaner cooking fuel alternatives. Composting biomass to produce CBM gas could offer a sustainable and accessible solution at the village level, reducing dependence on traditional biomass fuels.
    • Investment and Infrastructure: Implementing alternative fuel solutions such as CBM gas production requires investment and infrastructure development. Panchayats and local authorities may need support and resources to establish and maintain CBM gas production facilities effectively.
    • Rural Empowerment: Empowering local communities, such as Panchayats, to take initiatives in clean cooking fuel production and distribution can promote self-sufficiency and sustainability while addressing rural energy needs.

    To resolve the challenges associated with the Pradhan Mantri Ujjwala Yojana (PMUY) and ensure effective adoption of clean cooking practices, several measures can be implemented:

    • Awareness and Education Campaigns: Launch comprehensive awareness campaigns to educate PMUY beneficiaries about the health and environmental benefits of using LPG over traditional biomass fuels. Emphasize the importance of consistent LPG usage and the risks associated with indoor air pollution.
    • Subsidy Reforms: Implement sustainable subsidy structures that ensure long-term affordability of LPG cylinders for PMUY beneficiaries. Explore innovative subsidy mechanisms, such as targeted subsidies based on income levels or usage patterns, to address affordability concerns effectively.
    • Incentives for Refills: Introduce incentives or rewards for PMUY beneficiaries who consistently use and refill their LPG cylinders. This could include discounts on future refills or loyalty programs to encourage regular usage and reduce the gap between LPG connections and actual adoption.
    • Improved Distribution Networks: Invest in improving last-mile connectivity and distribution networks in remote rural areas to ensure seamless access to LPG cylinders for all PMUY beneficiaries. This could involve expanding the reach of LPG distribution centers and leveraging technology for efficient logistics management.
    • Promotion of Alternative Fuel Solutions: Encourage the adoption of alternative fuel solutions such as Bio gas production through community-based initiatives. Provide support and incentives for the establishment of Bio gas production facilities at the village level, empowering local communities to produce and access clean cooking fuel.
    • Partnerships and Collaboration: Foster partnerships between government agencies, private sector stakeholders, and non-profit organizations to address the multifaceted challenges associated with clean cooking fuel adoption. Collaborative efforts can leverage expertise, resources, and networks to achieve sustainable solutions.
    • Monitoring and Evaluation: Establish robust monitoring and evaluation mechanisms to track the progress of PMUY implementation and measure the impact of interventions. Regular assessment of refill rates, usage patterns, and health outcomes can inform evidence-based policy decisions and program adjustments.

    Conclusion

    To curb black carbon emissions, India must address gaps in LPG adoption by PMUY beneficiaries through subsidy reforms, awareness campaigns, improved distribution networks, and promotion of alternative fuel solutions, fostering partnerships for sustainable impact.
