Study Notes
Water Resources
- Water is essential for life on Earth
- Freshwater is obtained from precipitation, surface runoff, and groundwater
- Water is continuously renewed through the hydrological cycle, making it a renewable resource
- Despite this, water scarcity is a global issue, predicted to affect nearly two billion people by 2025
- Water scarcity is often linked to low rainfall or drought-prone regions, but unequal access and over-exploitation are equally important factors
Water Scarcity and Conservation
- Water scarcity is caused by variations in rainfall, over-exploitation of water resources, and unequal access to water amongst different social groups
- Regions like Rajasthan, with their low rainfall, are often associated with water scarcity; however, the issue is widespread
- Increased population and the demands of agriculture and industry exacerbate water scarcity issues
Multi-Purpose River Projects
- Dams, reservoirs, and irrigation channels have been used for managing water resources for centuries
- Multi-purpose projects aim to provide multiple uses (e.g., irrigation, electricity generation, flood control) from a single river system
- Modern multi-purpose projects have come under scrutiny for their impact on the environment, displacement of communities (due to land acquisition), and disruption of ecosystems
Traditional Rainwater Harvesting
- Ancient civilizations developed effective water harvesting techniques tailored to local ecological conditions
- Rooftop harvesting, using tanks or cisterns, was and still is a widespread practice, especially in arid and semi-arid regions
- Traditional techniques often involved creating collection surfaces (like 'kuls' or diversion channels) to collect rainwater and direct it to storage basins
Modern Adaptations of Rainwater Harvesting
- Modern adaptations of rainwater harvesting techniques include using modern materials and methods to collect and store rainwater
- Initiatives like the rooftop rainwater harvesting programs in Tamil Nadu showcase successful modernization efforts to conserve water
