(c) In Gujarat, the Sabarmati basin farmers were agitated when higher priority was given to water supply in urban areas, particularly during droughts.
(d) Today in Rajasthan, the practice of rooftop rainwater water harvesting popularity has declined due to high water availability from Indira Gandhi Canal.
2. Answer the following questions in about 30 words.
(i) Explain how water becomes a renewable resource.
Answer:
Water can be considered as a renewable resource since there will be rain and surface water and groundwater will get recharged continuously due to the 3 processes involved in the hydrological cycle.
The 3 processes of the hydrological cycle are
- Evaporations
- Condensation
- Precipitation
(ii) What is water scarcity and what are its main causes?
Answer:
Many of our cities are such examples. Thus, water scarcity may be an outcome of a large and growing population and consequent greater demands for water, and unequal access to it. A large population requires more water not only for domestic use but also to produce more food. Hence, to facilitate higher food-grain production, water resources are being over-exploited to expand irrigated areas for dry-season agriculture.
Irrigated agriculture is the largest consumer of water. Most farmers have their own wells and tube wells in their farms for irrigation to increase their productivity. This has adversely affected the water availability and food security of the people.
(iii) Compare the advantages and disadvantages of multi-purpose river projects.
Answer:
Advantages:
- Irrigation
- Electricity generation
- Flood control
- Water supply for industrial and domestic purposes
- Tourist attraction
- Inland navigation
Disadvantages:
- The natural flow of water is affected
- Aquatic life is affected
- Submergence of land in the surrounding areas
- Ecological consequences
- Large-scale displacement of local people
3. Answer the following questions in about 120 words.
(i) Discuss how rainwater harvesting in semi-arid regions of Rajasthan is carried out.
Answer:
In the semi-arid and arid regions of Rajasthan, particularly in Bikaner, Phalodi, and Barmer, almost all the houses traditionally had underground tanks or tankas for storing drinking water. The tanks could be as large as a big room; one household in Phalodi had a tank that was 6.1 meters deep, 4.27 meters long, and 2.44 meters wide. The tankas were part of the well-developed rooftop rainwater harvesting system and were built inside the main house or the courtyard. They were connected to the sloping roofs of the houses through a pipe.
Rain falling on the rooftops would travel down the pipe and be stored in these underground ‘tanks’. The first spell of rain was usually not collected as this would clean the roofs and the pipes. The rainwater from the subsequent showers was then collected. The rainwater can be stored in the tankas till the next rainfall, making it an extremely reliable source of drinking water when all other sources are dried up, particularly in the summers. Rainwater, or ‘palar pani’, as commonly referred to in these parts, is considered the purest form of natural water.
(ii) Describe how modern adaptations of traditional rainwater harvesting methods are being carried out to conserve and store water.
Answer:
A water harvesting system is a viable alternative, both socio-economically and environmentally. In ancient India, along with the sophisticated hydraulic structures, there existed an extraordinary tradition of water-harvesting systems. People had in-depth knowledge of rainfall regimes and soil types and developed wide-ranging techniques to harvest rainwater, groundwater, river water, and floodwater in keeping with the local ecological conditions and their water needs. In hill and mountainous regions, people built diversion channels like the ‘guls’ or ‘kuls’ of the Western Himalayas for agriculture. ‘Rooftop rainwater harvesting’ was commonly practiced to store drinking water, particularly in Rajasthan.
In the flood plains of Bengal, people developed inundation channels to irrigate their fields. In arid and semi-arid regions, agricultural fields were converted into rain-fed storage structures that allowed the water to stand and moisten the soil like the ‘khadins’ in Jaisalmer and ‘Johads’ in other parts of Rajasthan. In Gendathur, a remote backward village in Mysuru, Karnataka, villagers have installed, on their household’s rooftop, a rainwater harvesting system to meet their water needs. Nearly 200 households have installed this system and the village has earned the rare distinction of being rich in rainwater. Rooftop rainwater harvesting is the most common practice in Shillong, Meghalaya.
It is interesting because Cherapunjee and Mawsynram situated at a distance of 55 km. from Shillong receive the highest rainfall in the world. Yet, the state capital Shillong faces an acute shortage of water. Nearly every household in the city has a rooftop rainwater harvesting structure. Nearly 15-25 percent of the total water requirement of the household comes from rooftop water harvesting. Tamil Nadu is the first state in India that has made rooftop rainwater harvesting structures compulsory for all houses across the state.
