Question Explain how water becomes a renewable resource. This freshwater is mainly obtained from surface run off and ground water that is continually being renewed and recharged through the hydrological cycle. All water moves within the hydrological cycle ensuring that water is a renewable resource. Solution: Water scarcity is the shortage of water but it is not only Ncert Solutions For Class 10th Geography Chapter 6 Year associated with regions having low rainfall or those that are drought-prone. The availability of water resources varies over space and time, mainly due to the variations in seasonal and annual precipitation, but water scarcity in most cases is caused by overexploitation, excessive use and unequal access to water among different social groups.
Dams also fragment rivers making it difficult for aquatic fauna to migrate, especially for spawning. It has great ecological consequences like salinisation of the soil. At the same time, it has transformed the social landscape i.
The dams that were constructed to control floods have triggered floods due to sedimentation in the reservoir. Moreover, the big dams have mostly been unsuccessful in controlling floods at the time of excessive rainfall. It was also observed that the multi-purpose projects induced earthquakes, caused waterborne diseases and pests and pollution resulting from excessive use of water. Solution: In the semi-arid and arid regions of Rajasthan, particularly in Bikaner, Phalodi and Barmer, almost all the houses traditionally had Ncert Solutions For Class 10th Geography Chapter 7 List underground tanks or tankas for storing drinking water.
The tanks could be as large as a big room. 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. 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. Solution: Fortunately, in many parts of rural and urban India, rooftop rainwater harvesting is being successfully adapted to store and conserve water. Nearly households have installed this system and the village has earned the rare distinction of being rich in rainwater.
Rainwater harvesting is once again being conserved through modern adaptation. Rainwater running down from the roofs is not fed into drains. Instead it is piped into underground reservoirs.
