Study Notes
Water Scarcity
- Water scarcity is a significant issue driven by rising populations and poor water quality.
- Urbanization and industrialization in post-independence India have exacerbated water supply challenges.
- Heavy industrial use of water and pollution from chemicals, wastes, and agriculture lead to declining groundwater levels.
- Water-borne diseases and environmental degradation associated with excessive water use are emerging concerns.
Historical Water Management and Dams
- Bhopal Lake, a major artificial lake from the 11th century, and the 14th-century Hauz Khas tank illustrate historical water management efforts.
- Dams are built to manage rivers and rainwater; they are classified by structure (embankment, masonry) and height (low, medium, high).
- Jawaharlal Nehru referred to dams as "temples of modern India," aiming to promote agricultural and industrial development.
Agricultural Practices and Consequences
- Shift to water-intensive crops has ecological implications, including soil salinization and erosion.
- Sedimentation reduces nutrient availability, negatively impacting agricultural productivity.
- The Pradhan Mantri Krishi Sinchaee Yojana aims to provide irrigation access to farmers, enhancing agricultural sustainability.
Traditional Water Harvesting
- Ancient water-harvesting methods include khadins and johads, particularly in Rajasthan.
- Rooftop rainwater harvesting has been a traditional practice but is declining in some areas due to reliance on alternative water sources.
- Tamil Nadu mandates rooftop rainwater harvesting systems in homes, promoting sustainable water management.
Bamboo Drip Irrigation in Meghalaya
- A 200-year-old bamboo drip irrigation system channels water from springs to agricultural areas using gravity.
- This method allows for efficient water delivery directly to the roots of plants, minimizing waste and ensuring effective irrigation.
Key Challenges and Future Directions
- Despite advances, many regions still lack access to clean and adequate water supply.
- Ongoing industrial pollution threatens the integrity of water resources, necessitating stricter regulations and sustainable practices.
- Community engagement and education on water conservation and management strategies are essential for addressing water scarcity issues.
