Study Notes
Water Scarcity and Its Causes
- Over three-fourths of Earth's surface is covered with water, but only a small fraction is freshwater usable for consumption.
- Freshwater sources include surface runoff and groundwater, which are renewed via the hydrological cycle.
- Despite the renewability of water, water scarcity is prevalent in many regions due to low rainfall or drought-prone areas.
Predictions and Global Impact
- By 2025, an estimated two billion people may live in absolute water scarcity.
- Water scarcity arises mainly from over-exploitation of water resources, excessive usage, and inequitable access among different social groups.
- A growing population increases domestic water needs and food production demands, exacerbating water stress.
Agriculture and Water Over-Use
- Irrigated agriculture is the largest consumer of freshwater, driving the over-exploitation of water resources.
- Expansion of irrigated areas for dry-season agriculture further intensifies water demand.
- Innovative approaches such as developing drought-resistant crops and dry farming techniques are essential to mitigate water scarcity.
Urbanization and Water Quality
- Many cities face significant water issues, even if general water resources seem sufficient.
- Poor water quality can lead to scarcity despite the availability of water; pollution from industrial and residential waste threatens safe drinking water.
- Post-independence India has seen rapid industrialization, leading to increased pressure on freshwater resources.
Government Interventions
- The Government of India prioritizes improving life quality, especially in rural areas, through initiatives like the Jal Jeevan Mission (JJM).
- JJM aims to ensure assured water supply to every rural household, focusing on rural development and water management.
