Model Answer
Causes of Growing Human-Wildlife Conflict in India-wildlife conflict (HWC) in India is escalating due to several interrelated factors:
- Habitat Depletion and Fragmentation: Rapid urbanization, agricultural expansion, and infrastructure development have led to significant habitat loss for wildlife. This forces animals to venture into human settlements in search of food and water.
- Movement of Livestock and Humans: Economic pressures compel marginalized communities to exploit resources within protected areas, increasing encounters with wildlife.
- Invasive Alien Species: The introduction of non-native species can disrupt local ecosystems, reducing food and water availability for native wildlife, which in turn leads to competition with humans.
- Climatic Factors: Climate change alters vegetation patterns and affects the foraging behavior of species like lions and leopards, increasing the likelihood of conflict with humans.
- Increase in Wildlife Populations: Conservation efforts have successfully increased the populations of certain species, which can exceed the carrying capacity of their habitats, leading to “spillover” into human areas.
- Stochastic Events: Natural disasters such as floods and forest fires can displace wildlife, forcing them into populated areas in search of food and shelter.
Government Measures to Mitigate Human-Wildlife Conflict
The Indian government has implemented several strategies to address HWC:
- National Human-Wildlife Conflict Mitigation Strategy: This framework aims to tackle the root causes of conflict through a structured approach focusing on drivers, pressures, and responses.
- Standing Committee of National Board of Wildlife Guidelines: These guidelines promote community involvement, provide crop loss insurance, and establish early warning systems to mitigate conflict.
- Legislative Framework: Laws such as the Wildlife Protection Act of 1972 and the National Biodiversity Act of 2002 protect wildlife and their habitats, facilitating the creation of protected areas.
- State-Level Initiatives: States like Kerala and Uttarakhand have formed committees to address HWC and implement localized solutions.
- Creation of Wildlife Corridors: States including Kerala and Madhya Pradesh have developed corridors to allow the safe movement of wildlife between habitats, reducing encounters with humans.
- Funding and International Cooperation: The central government provides financial support for wildlife conservation, and projects like the Indo-German Human-Wildlife Conflict Mitigation Project aim to establish best practices for coexistence.
While completely eradicating human-wildlife conflict is challenging, these integrated approaches can foster coexistence between humans and wildlife.

Impact of Infrastructure Development Projects on Fragile Ecosystems and Mitigation Strategies
Infrastructure development projects such as roads, dams, and urban expansion are essential for economic growth but can have significant impacts on fragile ecosystems. These impacts can disrupt biodiversity, alter natural habitats, and affect local communities. A critical examination of these effects, along with mitigation strategies, is crucial for balancing development with environmental conservation. Below, we analyze the impacts and propose strategies to mitigate them, supported by recent examples.
1. Disruption of Biodiversity and Habitat Loss
Infrastructure projects often lead to habitat loss and biodiversity disruption as natural areas are cleared or altered.
Example: The Western Ghats in India: The construction of highways and roads in the Western Ghats, a biodiversity hotspot, has led to habitat fragmentation. This fragmentation affects wildlife such as the Nilgiri tahr and Asian elephant, which depend on continuous forest cover for their survival.
Example: The Amazon Rainforest: Large-scale infrastructure projects, including highways and dams, have led to significant deforestation in the Amazon. The Trans-Amazonian Highway, for instance, has accelerated habitat loss and biodiversity decline in one of the world’s most important ecosystems.
2. Alteration of Water Resources and Soil Erosion
Infrastructure development can alter water resources and lead to soil erosion, affecting local ecosystems and communities.
Example: The Three Gorges Dam in China: The construction of the Three Gorges Dam has significantly altered the Yangtze River’s flow, impacting aquatic ecosystems and leading to soil erosion and sedimentation issues downstream. This has affected species such as the Yangtze giant softshell turtle and disrupted local fisheries.
Example: The Narmada Dam in India: The Sardar Sarovar Dam on the Narmada River has caused significant displacement of local communities and altered river flow, impacting the surrounding ecosystems. The project has led to concerns about reduced water availability and changes in local flora and fauna.
3. Pollution and Environmental Degradation
Infrastructure projects often lead to pollution and environmental degradation, impacting air, water, and soil quality.
Example: The Delhi Metro Project: While the Delhi Metro has improved urban transportation, its construction led to air and soil pollution in several areas. The excavation and construction activities caused significant dust and particulate matter pollution, impacting local air quality.
Example: The Chhattisgarh Coal Mining Projects: The expansion of coal mining in Chhattisgarh has led to pollution and environmental degradation. Mining activities have resulted in deforestation, water contamination, and adverse health effects on nearby communities.
4. Mitigation Strategies
To address the adverse impacts of infrastructure development on fragile ecosystems, several mitigation strategies can be employed:
Environmental Impact Assessments (EIAs): Comprehensive EIAs should be conducted before project approval to identify potential environmental impacts and develop mitigation measures. For example, the EIA for the Posco Steel Plant in Odisha was revised multiple times to address environmental and social concerns raised by various stakeholders.
Wildlife Corridors and Protected Areas: Establishing wildlife corridors and expanding protected areas can help mitigate habitat fragmentation. The Corbett-Palain Corridor in Uttarakhand is an example where efforts have been made to create safe passageways for wildlife affected by infrastructure development.
Sustainable Design and Construction Practices: Implementing sustainable design and construction practices can reduce the environmental footprint of infrastructure projects. The Green Building Movement in India promotes sustainable architecture and construction practices, including the use of eco-friendly materials and energy-efficient designs.
Community Involvement and Compensation: Engaging local communities in the planning process and providing adequate compensation can help address displacement and socio-environmental impacts. The Community Forest Rights Act (2006) in India provides a framework for recognizing and compensating local communities affected by development projects.
Restoration and Rehabilitation: Post-project restoration and rehabilitation efforts can help restore degraded ecosystems. The Kutch Desert Wildlife Sanctuary Restoration Project in Gujarat focuses on rehabilitating and restoring the natural habitats affected by previous development activities.
Conclusion
See lessInfrastructure development projects, while crucial for economic progress, can have significant impacts on fragile ecosystems. Addressing these impacts requires a multifaceted approach that includes thorough environmental assessments, sustainable practices, and active community engagement. By implementing effective mitigation strategies, it is possible to balance development with ecological preservation and ensure that infrastructure projects contribute positively to both human and environmental well-being.
