MAINS PREVIOUS YEAR QUESTIONS (Unit 2 )
Q.1) Enumerate the National Water Policy of India. Taking river Ganges as an example, discuss the strategies which may be adopted for river water pollution control and management. What are the legal provisions of management and handling of hazardous wastes in India? (2013)
Introduction | Water is a vital natural resource, essential for life, environment, and development. Recognizing the growing demand, declining quality, and competing uses of water, the Government of India formulated the National Water Policy (NWP) in 1987, revised in 2002 and 2012, to guide sustainable water resource development and management. Rivers like the Ganges, lifelines to millions, have been under severe ecological stress due to pollution, calling for robust strategies and legal safeguards, including for hazardous waste management. |
Body | National Water Policy of India: Key Provisions
Strategies for River Water Pollution Control and Management: The Case of River Ganges The Ganges suffers from heavy pollution from sewage, industrial effluents, religious activities, and agricultural runoff. Strategies can include: Sewage and Wastewater Management
Industrial Pollution Control
Solid Waste Management
Ecological Measures
Community and Institutional Measures
Legal Provisions for Management and Handling of Hazardous Wastes in India Hazardous wastes are regulated to protect human health and environment. Key legal provisions include:
|
Conclusion | India’s National Water Policy emphasizes sustainability, efficiency, and participatory governance of water resources. The Ganges, a symbol of India’s cultural and ecological heritage, requires integrated and sustained efforts to restore its health. Strengthened legal and institutional mechanisms for hazardous waste management further complement the broader objective of environmental conservation and sustainable development. |
Q.2 ) Discuss the Namami Gange and National Mission for Clean Ganga (NMCG) programmes and causes of mixed results from the previous schemes. What quantum leaps can help preserve the river Ganga better than incremental inputs? (2015)
Introduction | The river Ganga is India’s most important river — ecologically, culturally, and economically — supporting the livelihoods and spiritual needs of over 400 million people. However, decades of pollution from untreated sewage, industrial effluents, and religious activities have degraded its water quality. To address this, the National Mission for Clean Ganga (NMCG) and the flagship Namami Gange programme were launched to rejuvenate the river and ensure its ecological and cultural integrity. |
Body | Namami Gange and NMCG: Key Features National Mission for Clean Ganga (NMCG):
Namami Gange Programme (launched in 2014):
Reasons for Mixed Results of Previous Schemes Despite initiatives like Ganga Action Plan (1986) and subsequent efforts, outcomes have been below expectations due to:
Quantum Leaps Needed for Better Outcomes To truly rejuvenate the Ganga, incremental steps must be complemented by bold, systemic changes: River Basin Management Authority:
Full Sewage Coverage:
Strict Industrial Compliance:
Ecological Flow Norms:
Restoration of Tributaries:
Community-Led Movements:
Incentivize Sustainable Agriculture:
Integration with Climate Goals:
|
Conclusion | The health of the Ganga is critical to India’s ecological security, cultural identity, and socio-economic well-being. While the Namami Gange and NMCG have made progress in creating institutional capacity and initiating large-scale projects, their success depends on ambitious, holistic, and participatory approaches rather than fragmented, incremental measures. A truly clean and flowing Ganga will be a testament to India’s commitment to sustainable development and environmental stewardship. |
Q.3) Comment on the National Wetland Conservation Programme initiated by the Government of India and name a few of India’s wetlands of international importance included in the Ramsar Sites. (2023)
Introduction | Wetlands are vital ecosystems that provide a range of ecological services including water purification, flood mitigation, carbon sequestration, and biodiversity conservation. Recognizing their importance, the Government of India launched the National Wetland Conservation Programme (NWCP) in 1985–86 to protect and restore wetlands. India is also a signatory to the Ramsar Convention (1971), which provides a framework for the conservation of wetlands of international importance. |
Body | National Wetland Conservation Programme (NWCP): An Overview · Objective: To prevent further degradation of wetlands and promote their wise use for ecological and socio-economic benefits. · Key Features: o Provides financial and technical support to States/UTs for the conservation and management of wetlands. o Formulates guidelines and policies for wetland conservation. o Identifies and maintains an inventory of wetlands in India. o Creates awareness and capacity building for wetland-dependent communities and local governments. · Critique: o The NWCP laid an important foundation for wetland conservation in India, covering over 115 wetlands. o However, it suffered from limited funding, overlapping jurisdiction, and lack of strong legal backing. o Absence of community participation and clear demarcation of wetland boundaries also constrained its effectiveness. o In 2017, the Wetlands (Conservation and Management) Rules superseded earlier provisions to bring more accountability and clarity in governance. India’s Wetlands of International Importance (Ramsar Sites) India, as a Ramsar Convention member, has 75 wetlands designated as Ramsar Sites (as of 2023) — the highest in Asia — covering over 1.3 million hectares. Some notable Ramsar sites include:
|
Conclusion | The NWCP marked an important policy intervention in India’s wetland conservation journey, highlighting the government’s commitment to preserving these critical ecosystems. Strengthening institutional mechanisms, enhancing community participation, and integrating conservation with sustainable development are essential to achieve the Ramsar vision of “wise use of wetlands” in India. |
Q.4) What is a wetland? Explain the Ramsar concept of ‘wise use’ in the context of wetland conservation. Cite two examples of Ramsar sites from India. (2018)
Introduction | A wetland is a transitional ecosystem between terrestrial and aquatic habitats, where the water table is at or near the surface or the land is covered by shallow water. According to the Ramsar Convention (1971), wetlands include marshes, swamps, peatlands, estuaries, mangroves, lagoons, lakes, and even some human-made water bodies, whether natural or artificial, permanent or temporary, with water that is static or flowing, fresh, brackish or saline. |
Body | Ramsar Concept of ‘Wise Use’
Key features of wise use:
Examples of Ramsar Sites from India India is a signatory to the Ramsar Convention and, as of now, has 75 Ramsar sites. Two notable examples:
|
Conclusion | Wetlands are vital ecosystems providing numerous ecological, economic, and cultural services. The Ramsar concept of wise use underlines the importance of sustainable management of wetlands, ensuring that conservation and development go hand in hand. Strengthening community involvement, enforcing regulations, and integrating wetland management into national planning are essential for achieving this vision. |
