Q1: Read the given source and answer the questions that follow:
RAINWATER HARVESTING
Many thought that given the disadvantages and rising resistance against the multi purpose projects, water harvesting system was 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 system. People had in-depth knowledge of rainfall regimes and soil types and developed wide ranging techniques to harvest rainwater, groundwater, river water and flood water 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 practised to store drinking water, particularly in Rajasthan. In the flood plams 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.
(i) Why is water harvesting system a viable alternative?
(ii) Describe the process of 'rooftop rainwater harvesting.'
(iii) Mention any two methods adopted by ancient India for water conservation.

Ans: (i) The water harvesting system emerges as a viable alternative due to its dual benefits—socio-economic and environmental friendliness.
(ii) 'Rooftop Rainwater Harvesting' involves capturing rainwater from the roof, storing it in reservoirs, and providing a sustainable source of drinking water, especially notable in Rajasthan.
(iii) Ancient India employed diverse water conservation methods, such as building diversion channels like 'guls' or 'kuls' in the Western Himalayas for agriculture and creating rainfed storage structures like 'Khadins' in Jaisalmer and 'Johads' in Rajasthan's other regions.

Q2: "Water scarcity may be an outcome of large and growing population in India." Analyse the statement. 

Sure Shot Questions for Board Exams: Water Resources | Social Studies (SST) Class 10View Answer  Sure Shot Questions for Board Exams: Water Resources | Social Studies (SST) Class 10

Ans:  Water scarcity in India is exacerbated by its large and growing population:

  • Greater demands for water arise not only from domestic use but also from increased food production.
  • Densely populated areas experience groundwater over-exploitation, significantly lowering water tables.
  • Industrial demands and associated pollution further strain freshwater resources, contributing to water scarcity in many Indian cities.

Q3: "Multi-purpose projects and large dams have been the cause of many new social movements." Highlight the concerns related to such movements.

Ans: Resistance to these projects (Narmada Bachao Andolan and Tehri Dam Andolan) has primarily been due to the large-scale displacement of local communities. So, if the local people are not benefiting from such projects then who is benefited? With abundance of water many farmers shifting to water intensive and commercial crops. This has great ecological consequences like salinization of the soil. It has transformed the social landscape i.e. increasing the social gap between the richer landowners and the landless poor.

Q4: "Urbanisation has added to water scarcity." Support the statement with arguments.

Ans: Urbanization exacerbates water scarcity in India due to:

  • Increased water demand for personal use in densely populated urban centers.
  • Over-exploitation of groundwater by housing societies and colonies.
  • Industries in urban areas contribute to water stress through high consumption and pollution.

Q5: "Water harvesting system is an effective measure to reduce the problem of water scarcity.” Justify the statement.

Ans: A large amount of this precious water just drains away. The only way to save this water from wastage is by rainwater harvesting. In its simplest form it involves storing the rainwater in tanks, or by making embankments etc. The different methods of rainwater harvesting used in India have been as follows:
(a) Guls or Kuls in the Western Himalayas.
(b) Rooftop rainwater harvesting in Rajasthan associated with tankas. Khadins in Jaisalmer and Johads in other parts of Rajasthan were also popular.
(c) Inundation channels in West Bengal
(d) In Meghalaya which gets copious rain, rainwater harvesting is commonly practiced.
(e) In modern civil construction and housing societies provision for rainwater harvesting.

Ans: In Meghalaya, a system of tapping stream and spring water by using bamboo pipes is prevalent. This system solved the problem of acute shortage of water, to some extent.

Q7: "Archaeological and historical records show that from ancient times we have been constructing sophisticated hydraulic structures in India.” Substantiate the statement by giving three evidences.

Ans: Archaeological and historical records reveal India's rich tradition of sophisticated hydraulic structures:

  • In the 1st century B.C., Sringaverapura near Allahabad showcased advanced water harvesting, channeling Ganga's floodwaters.
  • During Chandragupta Maurya's rule, extensive construction of dams, lakes, and irrigation systems occurred.
  • Evidence of sophisticated irrigation works is found in places like Kalinga, Nagarjunakonda, Bennur, and Kolhapur. In the 11th century, the construction of Bhopal Lake and the 14th-century tank in Hauz Khas, Delhi, further demonstrates India's historical prowess in hydraulic engineering.

Q8: "The dams that were constructed to control floods have triggered floods.” Analyze the statement.

Ans: Damming of rivers affects their natural flow causing poor sediment flow and excessive sedimentation at the bottom of the reservoir, and poorer habitat for the rivers’ aquatic life. Dams also fragment rivers making it difficult for aquatic fauna to migrate, especially for spawning. Reservoirs created on the floodplains also submerge the existing vegetation and soil leading to its decomposition.

Ans: Water scarcity in most cases results from over-exploitation, excessive use, and unequal access among social groups:

  • Over-exploitation is evident through extensive tubewell use for irrigation and industrial purposes.
  • Excessive use is seen in urban areas where water is wasted due to inadequate recycling.
  • Unequal access is apparent with affluent individuals having ample water while the poor face limited supply.

FAQs on Sure Shot Questions for Board Exams: Water Resources - Social Studies (SST) Class 10

1. What are the main sources of water resources?
Ans. The main sources of water resources include surface water, which consists of rivers, lakes, and reservoirs; groundwater, found in aquifers beneath the earth's surface; and precipitation, which includes rain and snow. Each of these sources plays a crucial role in providing water for domestic, agricultural, and industrial uses.
2. How does water scarcity impact agriculture?
Ans. Water scarcity can severely impact agriculture by reducing crop yields and affecting food production. Insufficient water supply can lead to drought conditions, which can hinder plant growth, cause soil degradation, and increase the reliance on irrigation. This results in higher costs for farmers and can lead to food shortages.
3. What measures can be taken to conserve water resources?
Ans. To conserve water resources, various measures can be implemented, such as promoting water-efficient irrigation techniques, repairing leaks in water supply systems, recycling wastewater, and encouraging the use of drought-resistant crops. Public awareness campaigns and stricter regulations on water usage can also help in conserving water.
4. What is the role of water management in sustainable development?
Ans. Water management plays a critical role in sustainable development by ensuring the efficient and equitable distribution of water resources. Proper management helps to balance the needs of agriculture, industry, and communities while protecting ecosystems. Sustainable practices help to preserve water quality and availability for future generations.
5. How does urbanization affect water resources?
Ans. Urbanization affects water resources by increasing demand for water due to higher population densities and industrial activities. It can lead to pollution of water bodies from runoff and waste, over-extraction of groundwater, and increased pressure on existing water supply systems. Effective urban planning is essential to mitigate these impacts.
