  • Wildlife Conservation Efforts

    A turf war with the wild

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Forest in Kerala and comparison with forest in other states

    Mains level: Measures to address human-wildlife conflict

    Why in the news?

    • Instances of human-animal conflict are on the rise in Kerala with the summer heat, scarcity of food, and loss of habitat forcing wild animals to stray into human habitations for sustenance.

    Context-

    • Vulnerability of tribal communities living in such areas. While they have intricate knowledge of the forest and its resources, they lack the protective measures and resources available to more urbanized populations, leaving them more susceptible to the dangers of wildlife encounters.

    Human-animal conflict in Kerala-

    • Surge in Incidents: Kerala has experienced a significant increase in human-animal conflict incidents across its districts, attributed to the state’s significant forest cover and densely populated settlements near wildlife habitats.
    • Human Casualties: Human-wildlife conflicts have resulted in a substantial loss of human lives, with 93 reported deaths in 2023-24. The previous year recorded 98 human casualties.
    • Hotspot District: Wayanad stands out as a hotspot for human-animal conflicts, with 69 reported deaths between 2011 and 2024. Incidents involve encounters with wild elephants and, in one case, a tiger attack.
    • Diverse Wildlife Involved: Human-animal conflicts in Kerala involve various species, including elephants, tigers, leopards, bears, wild gaurs, wild boars, and monkeys. This diversity underscores the complexity of managing conflicts across different ecosystems and habitats.
    • Impact on Livelihoods: The conflicts have severe repercussions on people’s livelihoods, particularly those dependent on agriculture and farming. Attacks by wild animals prevent farmers from cultivating their land, leading to economic hardship and food insecurity.
    • Vulnerable Communities: Vulnerable communities like tribal groups and small-scale farmers are disproportionately affected by human-animal conflicts. Limited resources and infrastructure exacerbate their vulnerability to wildlife attacks, as seen in the case of Abraham Palatt and his family.

    Steps taken by Government to deal these issues – 

    • State-Specific Disaster: The Kerala government declared human-animal conflict as a state-specific disaster in March, becoming the first state to do so. This decision signifies the severity and urgency of addressing the issue.
    • Responsibility Shift: Management of human-animal conflicts now falls under the purview of the Kerala State Disaster Management Authority (KSDMA), with a committee headed by the Chief Minister established for this purpose.
    • Community Involvement: The government plans to involve local communities through neighborhood groups to enhance surveillance on forest fringes. These groups will collaborate with government agencies and elected representatives to disseminate alerts about wildlife presence.
    • Recruitment and Equipment: The government aims to strengthen surveillance by recruiting more forest watchers and establishing rapid response teams equipped with firearms, surveillance devices, drones, tranquilizing guns, and advance warning systems.
    • Inter-State Collaboration: An inter-State coordination committee involving the Forest departments of Karnataka, Kerala, and Tamil Nadu has been formed to address human-wildlife conflicts collectively. This initiative aims to share intelligence and resources to mitigate conflicts, particularly along interstate borders.

    Measures to address human-wildlife conflict-

    • Forest Quality Improvement: Improving the quality of forests through measures such as reducing fragmentation and patchiness can help create healthier ecosystems that support a more balanced coexistence between humans and wildlife.
    • Conservation Mission with Tribal Communities: Involving tribal communities in conservation efforts ensures their participation and traditional knowledge is valued. Collaborative conservation initiatives can promote sustainable practices and protect both biodiversity and livelihoods.
    • Rejuvenation of Natural Forest Streams: Restoring natural water sources in forests is crucial for wildlife habitat and can help mitigate conflicts by providing essential resources within their natural environment.
    • Removal of Invasive Plants and Replanting Indigenous Species: Removing invasive plant species and replanting indigenous ones can restore ecological balance and support native wildlife populations, reducing their reliance on human-impacted areas.
    • Utilization of MGNREGS: Leveraging government schemes like the Mahatma Gandhi National Rural Employment Guarantee Scheme (MGNREGS) to support conservation efforts can provide employment opportunities while simultaneously contributing to environmental restoration projects.
    • Awareness Programs on Responsible Tourism: Educating tourists about responsible behavior around wildlife can minimize human-wildlife conflicts caused by human disturbance. This includes emphasizing the importance of maintaining a safe distance and respecting wildlife habitats.
    • Effective Institutional Framework: Establishing a robust institutional framework at various levels of governance, from local to inter-state, is essential for coordinated action in managing human-wildlife conflicts. This involves collaboration between different government departments, wildlife authorities, and local communities.

    Conclusion-

    Human-wildlife conflicts surge in Kerala, endangering lives and livelihoods. Government initiatives, community involvement, and conservation efforts are crucial for mitigating conflicts and fostering coexistence, ensuring a sustainable future for both humans and wildlife.

    Subduction Zone discovered beneath Gibraltar Strait

    Note4Students

    From UPSC perspective, the following things are important:

    Prelims level: Gibraltar Strait, Tectonic Plate Boundaries, Subduction Zones

    Mains level: Read the attached story

    What is the news?

    • Scientists in Portugal have uncovered a concerning revelation about the fate of the Atlantic Ocean, highlighting a potential ‘Ring of Fire’ (a Subduction Zone).
    • Researchers caution that the Atlantic may be on the brink of closure due to subduction activity.

    Why discuss this?

     

    • Closure of Gibraltar Strait: Computer simulations project the subduction zone’s expansion over the next 20 million years, forming the ‘Ring of Fire’ in the Atlantic leading to the closure of Gibraltar Strait.
    • Geological Parallel: This process mirrors the Pacific Ocean’s Ring of Fire, reshaping the ocean basin through gradual subduction of the ocean floor beneath continents.

     

    About Gibraltar Strait

    Details
    Location
    • Connects the Atlantic Ocean to the Mediterranean Sea;
    • Separating the southern tip of the Iberian Peninsula of Europe from the northern coast of Africa.
    Width Approximately 13 km (8.1 miles) at its narrowest point.
    Depth Varies, with the deepest point reaching around 300 meters (984 feet).
    Formation
    • Convergence point for the Eurasian Plate and the African Plate.
    • Formed around 5.33 million years ago during the Messinian salinity crisis when the Atlantic Ocean breached the barrier separating it from the Mediterranean Sea, resulting in a catastrophic flood known as the Zanclean flood.
    • The strait’s current shape and depth were further influenced by tectonic movements and erosional processes over geological time.
    Historical Significance Serves as a key maritime passage for trade and military purposes.
    Disputes
    • Subject of contention between Spain and the United Kingdom;
    • Gibraltar Overseas Territory under British control.

     

    What are Subduction Zones?

    • Subduction zones occur at convergent plate boundaries, where two tectonic plates move toward each other.
    • This convergence is often between an oceanic plate and a continental plate or between two oceanic plates.
    • Subduction Process:
    1. Collision of Tectonic Plates: When two tectonic plates collide, the denser oceanic plate is forced beneath the less dense continental plate or another oceanic plate.
    2. Partial Melting: As the oceanic plate descends into the mantle, it generates intense heat and pressure, causing partial melting of the mantle material.
    3. Volcanic Activity: The molten material formed by the subduction process rises through the Earth’s crust, leading to volcanic eruptions at the surface.
    4. Formation of Volcanic Arcs: These eruptions often occur in chains known as volcanic arcs, which parallel the subduction zone. Ex. Andes in S. America; Cascade Range in North America.

    Implications of this Activity

    • Earthquakes: Subduction zone earthquakes can be particularly destructive and may trigger tsunamis due to the displacement of large volumes of water.
    • Trench Formation: The surface expression of a subduction zone is often a deep oceanic trench, where the descending plate bends and plunges into the mantle.
    • Mountain Building: Over time, the continuous subduction of oceanic crust can lead to the uplift and deformation of the overriding plate, resulting in the formation of mountain ranges adjacent to the subduction zone. These mountains may exhibit complex geological structures, including folds and faults.
    • Recycling of Oceanic Crust: As oceanic plates are subducted, they are gradually consumed by the mantle, releasing minerals and elements that are eventually returned to the surface through volcanic activity.
