Quick Revision: Solar fencing is a non-lethal, solar-powered electric barrier used to deter wild animals from entering human settlements, thereby mitigating human-wildlife conflict while ensuring animal welfare and ecological balance.

Why is this in the news?

The Kerala government’s decision to install 60 km of solar fencing in Wayanad district, along with a carrying capacity study by the Wildlife Institute of India (WII) and the deployment of Rapid Response Teams (RRTs), underscores the escalating human-wildlife conflict (HWC) in the region. This initiative is part of the state’s 100-day action programme and reflects a structured approach to mitigating HWC through technological, administrative, and ecological interventions. The announcement highlights the intersection of conservation policies, livelihood protection, and inter-governmental coordination in addressing a critical environmental governance challenge.

Background

• Wayanad district in Kerala is one of the most human-wildlife conflict-prone regions in India, owing to its dense forest cover, fragmented habitats, and proximity of human settlements to wildlife corridors.
• Human-wildlife conflict (HWC) in India primarily involves large mammals such as elephants, tigers, leopards, and wild boars, leading to crop raiding, livestock predation, and human casualties, thereby threatening rural livelihoods and conservation efforts.
• The Wildlife Institute of India (WII), an autonomous institution under the Ministry of Environment, Forest and Climate Change (MoEFCC), conducts scientific studies on wildlife populations, habitat carrying capacity, and conflict mitigation strategies.
• Solar fencing is an eco-friendly, non-lethal method of deterring wild animals from entering human settlements, using low-voltage electric pulses that do not harm the animals but create a psychological barrier.
• Kerala’s 100-day action programme is a state-led initiative aimed at expediting administrative reforms and infrastructure development, often leveraging inter-departmental coordination and community participation.
• The relocation of conflict-prone tigers to designated tiger reserves is a strategy under Project Tiger, governed by the National Tiger Conservation Authority (NTCA), to reduce HWC and enhance tiger conservation.

What is Solar Fencing and How Does It Address Human-Wildlife Conflict?

• Solar fencing is a wildlife deterrent system that utilises solar-powered electric fences to create a low-voltage barrier between human settlements and forest fringes, preventing wild animals from entering agricultural or residential areas.
• The system operates on a pulsed electric current (typically 5-6 kV) that delivers a mild shock to deter animals without causing physical harm, ensuring compliance with animal welfare standards and the Wildlife Protection Act, 1972.
• Solar fencing is particularly effective in mitigating conflicts involving elephants, wild boars, and tigers, as it provides a psychological barrier while allowing animals to move freely within their natural habitats.
• The Kerala government’s initiative to install 60 km of solar fencing in Wayanad is a proactive measure to protect crops, livestock, and human lives, while also reducing retaliatory killings of wildlife.
• The project includes the repair of existing 25 km of solar fencing, indicating a commitment to maintaining and upgrading existing infrastructure to enhance its efficacy.
• Solar fencing is part of a broader strategy that includes habitat management, community awareness, and rapid response mechanisms to address HWC holistically.
• The deployment of Rapid Response Teams (RRTs) in Wayanad within 100 days will enhance the Forest Department’s capacity to respond to wildlife emergencies, such as animal intrusions or attacks, thereby reducing human casualties and property damage.
• The initiative aligns with the principles of coexistence, ensuring that conservation efforts do not compromise the livelihoods of local communities while protecting wildlife.

Prelims Practice Questions

Q1. Consider the following statements regarding human-wildlife conflict (HWC) in India:
1. Human-wildlife conflict is primarily a rural phenomenon in India, with forest-fringe communities being the most affected.
2. The Wildlife Protection Act, 1972, provides the legal framework for mitigating HWC by empowering state governments to declare protected areas.
3. Solar fencing is a globally recognised non-lethal method for mitigating HWC, particularly for large mammals like elephants and tigers.

How many of the above statements are correct?

1. Only one
2. Only two
3. All three
4. None

Answer: All three — Statements 1 and 3 are correct. Statement 2 is incorrect because the Wildlife Protection Act, 1972, focuses on wildlife conservation and protection of habitats but does not explicitly empower state governments to declare protected areas; this is done under the Environment Protection Act, 1986, or state-specific notifications.

Q2. Assertion (A): The Wildlife Institute of India (WII) is mandated to conduct carrying capacity studies for forest ecosystems in India.
Reason (R): Carrying capacity studies are essential to determine the maximum sustainable population of wildlife species without causing ecological imbalance or human-wildlife conflict.

1. Both A and R are true, and R is the correct explanation of A
2. Both A and R are true, but R is NOT the correct explanation of A
3. A is true, but R is false
4. A is false, but R is true

Answer: Both A and R are true, and R is the correct explanation of A — Both Assertion (A) and Reason (R) are true, and Reason (R) correctly explains Assertion (A). The WII, an autonomous institution under the Ministry of Environment, Forest and Climate Change, conducts carrying capacity studies to assess the ecological limits of forest ecosystems and inform wildlife management policies.

Q3. Which of the following is NOT a measure typically adopted to mitigate human-wildlife conflict in India?

1. Installation of solar fencing along forest fringes
2. Relocation of wildlife species to designated reserves
3. Promotion of monoculture plantations in forest buffer zones
4. Deployment of Rapid Response Teams for emergency wildlife management

Answer: Promotion of monoculture plantations in forest buffer zones — Promotion of monoculture plantations in forest buffer zones is not a measure to mitigate human-wildlife conflict. Monoculture plantations often reduce biodiversity and can exacerbate conflicts by attracting herbivores to human settlements. The other options are standard mitigation strategies.
