Key Points: Water Resources of India
- Water Availability: India has 2.45% of world’s land, 4% of water resources and over 17% of world population. Total utilisable water is only 1,122 cubic km out of total availability.
- Surface Water: Major sources are rivers, lakes, ponds and tanks. Although annual river flow is high, only about 32% (690 cubic km) can be utilised due to geographical constraints. Ganga–Brahmaputra basins hold about 60% of surface water.
- Groundwater Resources: Total replenishable groundwater is 432 cubic km. States like Punjab, Haryana, Rajasthan and Tamil Nadu use groundwater heavily, leading to depletion.
- Lagoons and Backwaters: Coastal states like Kerala, Odisha and West Bengal have lagoons and lakes. Though water is brackish, it is used for fishing and irrigation.
- Water Utilisation Pattern: Agriculture dominates water use — 89% of surface water and 92% of groundwater is used for irrigation. Industrial and domestic use is comparatively low but increasing.
- Importance of Irrigation: Irrigation is necessary due to uneven and seasonal rainfall. It supports crops like rice, sugarcane and jute, enables multiple cropping, and increases productivity.
- Problems of Overuse: Excessive groundwater use has caused falling water table, and problems like fluoride (Rajasthan, Maharashtra) and arsenic contamination (West Bengal, Bihar).
CBSE: Class 12
Key Points: Emerging Water Problems
- Declining Per Capita Water Availability: Rapid population growth and rising demand are reducing per capita water availability in India.
- Water Pollution: Water gets polluted by industrial, agricultural and domestic wastes, which reduce water quality and make it unfit for human use.
- Impact on Rivers and Groundwater: Pollutants contaminate rivers, lakes and oceans, and may also seep into groundwater. Organic and bacterial pollution are major concerns.
- Highly Polluted Rivers: Rivers like Yamuna (Delhi–Etawah stretch), Ganga (Kanpur & Varanasi), Sabarmati, Gomti, Musi, Adyar and Cooum are severely polluted.
- Need for Water Conservation: Sustainable management requires rainwater harvesting, watershed development, recycling, reuse and conjunctive use of water.
- Weak Implementation of Laws: Acts like the Water Act (1974) and Environment Protection Act (1986) exist, but poor enforcement has limited their effectiveness.
- Recycle and Reuse: Recycling wastewater for industries, gardening and other non-drinking purposes can conserve fresh water and improve long-term availability.
CBSE: Class 12
Key Points: Watershed Management
- Meaning: Watershed management refers to the proper conservation and management of surface and groundwater resources within a watershed area.
- Main Objectives: It aims to prevent runoff, promote groundwater recharge (through percolation tanks, check dams, recharge wells), and ensure balanced use of natural and human resources.
- Community Participation: Success of watershed development depends largely on active involvement of local people and Gram Panchayats.
- Government Programmes: Major initiatives include Haryali Project and Atal Bhujal Yojana (ATAL JAL), which focus on water conservation and behavioural change towards sustainable water use.
- Water Harvesting Measures: Structures like johads, percolation tanks, check dams and dug ponds are built to store rainwater and recharge groundwater. Tamil Nadu has made rainwater harvesting compulsory in buildings.
- Ralegan Siddhi Example: In Maharashtra, watershed development through voluntary labour, banning water-intensive crops, afforestation and social reforms transformed the village economically and environmentally.
- Need for Awareness: Though some projects have succeeded, many are still at early stages. Greater awareness and integrated water resource management are essential for sustainable water availability.
CBSE: Class 12
Key Points: Rainwater Harvesting
- Meaning and Purpose: Rainwater harvesting is the method of collecting and storing rainwater for domestic use and groundwater recharge. It is a low-cost and eco-friendly technique.
- Benefits: It increases water availability, raises groundwater table, improves water quality (reduces fluoride and nitrates), prevents soil erosion, flooding, and saltwater intrusion in coastal areas.
- Traditional Methods: In rural India, rainwater is stored in ponds, tanks, lakes, etc. In Rajasthan, traditional structures like Kund and Tanka are used to store rainwater.
- National Water Policy 2012: It emphasizes water conservation, treating water as an economic resource, community participation, efficient use, climate change adaptation, and giving priority to drinking water and food security.
- Jal Kranti Abhiyan (2015–16): Launched to ensure water security by promoting water conservation, artificial recharge, pollution control, creation of ‘Jal Gram’, and spreading public awareness through community participation.
