(a) Multi-purpose projects bring water to those areas which suffer from water scarcity.
(b) Multi-purpose projects by regulating water flow helps to control floods.
(c) Multi-purpose projects lead to large-scale displacements and loss of livelihood.

(iii) Here are some false statements. Identify the mistakes and rewrite them correctly.
(a) Multiplying urban centers with large and dense populations and urban lifestyles have helped properly utilize water resources.
(b) Regulating and damming of rivers does not affect the river’s natural flow and its sediment flow.
(c) In Gujarat, the Sabarmati basin farmers were not 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 has gained popularity despite high water availability due to the Indira Gandhi Canal.

Ans: (a) Multiplying urban centers with large and dense populations and urban lifestyles have resulted in improper utilization of water resources.

(b) Regulating and damming of rivers does affect the river’s natural flow and its sediment flow.

(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.

The primary sources of freshwater are surface runoff and groundwater, which is continuously replenished and recharged by the hydrological cycle. These are the three steps in the hydrological cycle:

• Evaporations
• Condensation
• Precipitation

The hydrological cycle ensures that all water travels, making it a renewable resource.

(ii) What is water scarcity and what are its main causes?

When a region’s supply of potable, unpolluted water is insufficient to meet demand,  The lack of water is known as water scarcity,

Water resource availability fluctuates over time and geography, primarily due to differences in seasonal and annual precipitation, but in most situations, water shortage is brought on by overuse, excessive consumption, and uneven access to water among various socioeconomic groups.
Agriculture that is irrigated uses the most water overall. A huge population necessitates more water, both for home use and for food production. Therefore, water resources are being overused to increase irrigated areas for dry-season agriculture in order to promote higher food-grain output.

(iii) Compare the advantages and disadvantages of multi-purpose river projects.

Regulating River water by building dams or changing its direction offers stable water irrigation for agriculture, but on the other hand, it heavily damages our environment. Let’s examine the Advantages and Disadvantages of Multipurpose River projects.

Advantages of Multipurpose River projects

1. Irrigation- Building dams on river bodies provide continuous water sully through the year for irrigation.
2. Generation of electricity- Hydropower Generation through the dam is very frequent as fossil fuels are about to finish.
3. Flood prevention-Floods have been brought on by the dams that were built to manage floods as a result of sedimentation in the reservoir. The large dams have also generally failed to prevent flooding during periods of severe rainfall.

Disadvantages of Multipurpose River projects

1. Multipurpose river projects have poor aquatic ecosystems as their primary drawback. It is a result of significant sedimentation at the reservoir’s base, which creates rockier stream beds.
2. Multipurpose river projects also have the drawback of interfering with rivers’ natural flow, which results in inadequate sediment flow.
3. The vegetation and soil beneath the submerged water slowly decompose, making it difficult for aquatic animals to migrate and breed.

3 . Answer the following questions in about 120 words.
(i) Discuss how rainwater harvesting in semi-arid regions of Rajasthan is carried out.

Traditionally, nearly all the homes in Rajasthan’s semi-arid and desert regions, particularly in Bikaner, Phalodi, and Barmer, had subterranean tanks called tankas for storing drinking water. The tanks might be the size of a huge room. One Phalodi home had a tank that was 6.1 metres deep, 4.27 meters long, and 2.44 meters broad; the tanks may be as enormous as a large room. The tankas were constructed inside the main house or the courtyard and were a part of the sophisticated rooftop rainwater gathering system. They had a hose connecting them to the dwellings’ sloping roofs. These underground “tankas” served as storage spaces for rain that fell on the rooftops and traveled down the pipe.Rain from the rooftops would go down the pipe and be collected in these underground “tankas,” where it would be stored. Since the first downpour would clean the roofs and pipes, most people don’t collect it. Then, rainwater was collected from the succeeding showers. When all other supplies of drinking water have dried up, especially during the summer, the rainwater may be stored in the tankas until the next rainfall, making it an incredibly reliable source. The purest natural water is regarded to be rainwater, or “palar pani,” as it is known locally.

(ii) Describe how modern adaptations of traditional rainwater harvesting methods are being carried out to conserve and store water.

An environmentally and socio-economically sound alternative is a water harvesting system. There was a remarkable heritage of water harvesting systems in ancient India, combined with well-developed hydraulic constructions Rainwater Harvesting methods carried out to conserve and store water is

1. People in hilly and mountainous areas constructed irrigation channels for agriculture, similar to the “guls” or “kuls” of the Western Himalayas.
2. Tanks have traditionally been built in homes in Rajasthan’s semi-arid regions to store drinking water. They are substantial and a component of the sophisticated rooftop rainwater harvesting system. The tanks are built inside the main house or the courtyard and attached to the dwellings’ sloping roofs by a conduit. Rain that falls on the roof is carried down and stored in the tanks. The initial downpour is not collected since it cleans the pipes and roof. The ensuing spells’ rainwater is gathered. This water is a dependable source of water even when other sources have dried up and can be used until the next season.
3. Traditional rainwater gathering techniques, such as “the rooftop method,” are gaining popularity in India. About 200 families in Gendathur village, Mysore, have embraced the rooftop rainwa collection technique, making the village rich in rainwater. All homes in the state of Tamil Nadu are required to install rooftop rainwater collection systems.
