Chapter 3 - Water Resources
Introduction
Water Availability and Scarcity
  1. Earth's Water Composition:
      • 75% of the earth's surface is water-covered.
      • Only a small fraction is freshwater.
  1. Sources of Freshwater: i. Surface Runoff: Water flowing on the surface. ii. Groundwater: Water present underground.
  1. Hydrological Cycle:
      • Continuous renewal and recharging of water sources.
      • Ensures water is a renewable resource.
  1. Water Scarcity Paradox: i. Question: Despite abundant water and its renewability, why do regions suffer from water scarcity? ii. Prediction: By 2025, almost two billion people could face absolute water scarcity.
Water Scarcity and the need for Water Conservation and Management
Water Scarcity, Conservation, and Management
  1. Perception of Water Scarcity:
      • Despite water's abundance and renewability, scarcity is a concern.
      • Regions with low rainfall and drought-prone areas are often associated with water scarcity.
  1. Causes of Water Scarcity: i. Natural Factors: Variations in precipitation and seasonal changes. ii. Human-induced Causes: Over-exploitation, excessive use, and unequal access. iii. Population Growth: Greater population leads to higher water and food demands. iv. Irrigated Agriculture: Largest consumer of water; over-exploitation for increased food production. v. Industrialisation and Urbanisation: Industries are heavy users of water; urban centers exert pressure on water resources.
  1. Hydroelectric Power:
      • Contributes approximately 22% of total electricity in India.
      • Significant user of water resources.
  1. Water Quality Concerns: i. Pollution: From domestic and industrial wastes, chemicals, pesticides, and fertilizers. ii. Health Hazards: Polluted water can be hazardous for human use.
  1. Government Initiatives: The government of India focuses on providing access to safe drinking water.
  1. The Imperative of Water Management:
      • Need to ensure health safety, food security, livelihood continuity, and ecosystem protection.
      • Over-exploitation and mismanagement can lead to an ecological crisis.
Multi-Purpose River Projects and Integrated Water Resources management
  1. Historical Context:
      • Ancient practices: Hydraulic structures like dams, reservoirs, and canals for irrigation.
      • Post-Independence: Emphasis on multi-purpose river projects.
  1. Dams and Their Uses: i. Traditional Use: Impound rivers and rainwater for irrigation. ii. Modern Uses: Electricity generation, domestic & industrial water supply, flood control, recreation, navigation, fish breeding.
  1. Multi-Purpose Projects: i. Definition: Integration of various uses of impounded water. ii. Examples: Bhakra-Nangal project (Hydel power & irrigation), Hirakud project (Water conservation & flood control). iii. Significance: Viewed as key to national development. Nehru called dams the ‘temples of modern India’.
  1. Critique of Multi-Purpose Projects: i. Environmental Concerns: - Affect the natural flow of rivers. - Poor sediment flow, and excessive sedimentation. - Fragmentation of rivers impacting aquatic life. - Submergence of vegetation & soil. ii. Societal Concerns: - Large-scale displacement of communities. - Disparities in benefits: Favours landowners, industrialists, and urban areas. - Changes in cropping patterns; ecological consequences. - Salinisation of soil; widened social gap between rich and poor. iii. Conflicts and Disputes: - Conflicts over water use. - Interstate water disputes over costs and benefits. iv. Failure of Projects: - Dams triggering floods due to sedimentation. - Unsuccessful flood control during heavy rains. - Induced earthquakes, water-borne diseases, pests, pollution.
  1. Overall Perspective:
      • Dams and multi-purpose projects have both benefits and drawbacks.
      • Essential to balance development goals with environmental and societal concerns.
Rainwater Harvesting
  1. Background:
      • Multi-purpose projects faced resistance and disadvantages.
      • Water harvesting is seen as a socio-economically and environmentally viable alternative.
  1. Ancient Techniques:
      • i. Knowledge Base: Ancient India had a deep understanding of rainfall regimes and soil types.
      • ii. Techniques:
        • Himalayas: Diversion channels called 'guls' or 'kuls' for agriculture.
        • Rajasthan: 'Rooftop rainwater harvesting' for drinking water.
        • Bengal: Inundation channels for field irrigation.
        • Arid Regions: 'Khadins' in Jaisalmer and 'Johads' in Rajasthan.
  1. Tankas in Rajasthan:
      • i. Design: Large underground tanks for storing drinking water.
      • ii. Location: Inside the main house or courtyard.
      • iii. Connection: Linked to rooftops via pipes. Initial rain was used to clean pipes; subsequent rainwater was collected.
      • iv. Utility: Stored rainwater used for drinking, especially during summers.
      • v. Modern Context: Decline in use due to the availability of canal water, but some still prefer it over tap water.
  1. Modern Adaptation:
      • i. Decline and Revival: Decline in traditional methods, but revival in urban and rural areas.
      • ii. Gendathur Case:
        • Location: Mysuru, Karnataka.
        • Implementation: Rooftop rainwater harvesting in nearly 200 households.
        • Results: Each house collects about 50,000 liters annually. Combined annual harvest: 1,00,000 liters.
