Case Study 1:
Earth 3/4th surface is covered with water still there is water scarcity, though water is considered as renewable resource is availability is limited. A report by the NITI Aayog stated that around 2 lakh people die in India every year due to inadequate water supply. It is common perceptions that only dry states like Rajasthan face water problem but the myth is broken by the recent ground water crises in cities of Chennai and Delhi. Surprisingly lack of availability of water is also supplemented with quality of availability of water which is major source of many water prone diseases in India. Effective measures have to be taken by both state and central government to ensure water security to its citizens and problem should be resolved in time bound manner.
Q1 Water Water everywhere, not a drop to drink? Comment Mark 2
Answer Though 3/4th Earth surface is covered with water and it is natural resource most of the water is present in oceans which cannot be consume by human beings directly and consumption of water is water is more than its recharge rate hence there emerge a severe water scarcity problem in India.
Q2 Give reasons why rainfall rich states also face water scarcity problems? Mark 1
Answer Over exploitation of ground water mainly for irrigation and other commercial purposes by big MNCs , over population and changing lifestyles of urban and rural population are the major causes of water scarcity in rainfall rich states.
Q3 Write some government initiatives to solve the problem of water crises. Mark 1
Answer Jal Jeevan Mission ensure that every rural household get tap water at a service level of 55 litres per capita per day regularly this will prevent many water prone diseases in rural area.
Case Study 2:
Since the ancient times our ancestors knows the importance of water and its conversation and for that purpose they build multiple structures popularly known as dams. Not surprisingly
India has continued this tradition by building various dams alongside many river basins. India has 4,407 large dams, the third highest number in the world after China (23,841) and the USA (9,263). Jawaharlal Nehru proudly proclaimed the dams as “temples of modern India ,not only as a water reservoir dams have various multipurpose role to play. Dams now had become one of the symbols of advancement of science and technology in modern India.
Q1) Give an account for water conservation efforts done in ancient India. Mark 2
Answer Many dams were constructed in ancient India time like for an example in reign of Chandragupta Maurya Sudarshan Lake in Junagarh was build. In 11th century Bhopal lake was build and it was one of the biggest artificial lake of that time. An account of 14th century work hauz khas by Iltutmish can also be seen.
Q2) Apart from water reservoir what are the other purposes of building the dams? Mark 2
Answer Dams also used to produce hydroelectricity as 22% of India electricity demands is meet by dams only , also they are used for many other purpose like channelizing water for irrigation
Act as a place of tourism and so on.
Case Study 3:
The tragedy in Kerala has highlighted the risks of extra water accumulation in dams. Greater than 20 dams launched water that cascaded down the hills, leaving at the back of a trail of destruction. the opening of the gates of the Idukki dam, for instance, precipitated the Periyar river to swell rapidly and discharge seven lakh litres of water consistent with 2 days yet, the argument for dams — that they offer ingesting water and water for agriculture — is these days scientifically discredited. For independent geologists and hydrologists, dams represent a nightmare, an ephemeral triumph of engineering over common sense and the herbal sciences. Increasingly more, it is evident that dam proponents are ignoring critical decision-making records now to be had on patterns of rainfall, geology and climate change.
Q1) What are the various cons associated with dams? Mark 2
Ans Dams stops natural flow to water and hence create a migration problem for acquatic animals especially for spawning.
Large number of displacement for local area people take place and huge submerge of land and nearby area occurs which itself cause disruption in ecological balance. Also by alternating the very purpose of dam like giving priority to urban area create a resentment in local area people which ultimately leads to various social problem and movements like Narmada bachao Andolan.
Q2) Write about 5 dams and their respective rivers. Mark 2
Answer
Dams River
Sardar sarovar Narmada
Hirakud Mahanadi
Nagararjuna Sagar Krishna
Mettur Kaveri
Kota Barrage Chambal
Case Study 4:
Flash floods all through this year’s monsoon season have precipitated unprecedented damage to both lives and assets in Himachal Pradesh. The death toll has crossed 150, and the anticipated total loss quantities to ₹10,000 crore. although weather exchange is anticipated to have played a hand in inflicting the high precipitation leading to these flash floods, human brought about screw ups resulting from planned development have played a massive role in causing such giant losses. in the last five years (earlier than 2022), 1,550 humans misplaced their lives and almost 12,444 houses had been broken.
The IPCC (Intergovernmental Panel on climate exchange) VI record has actually said that the Himalayas and coastal regions of India can be the hardest hit via climate exchange inside the Himalayas, there may be a major pattern of accelerated precipitation going on in shorter periods of time. The India Meteorological department facts suggests that the everyday rainfall all through this era is anticipated to be among 720mm and 750 mm. but, in positive times, it has surpassed 888 mm in 2010 and 926.nine mm in 2018. This 12 months, the precipitation to this point has been attributed to the combined effect of the south-west monsoon with western disturbances. the total rainfall from June to this point become 511 mm.
Q1) Why dams failed to control the floods? Mark 2
Answer Ironically, the dams that were constructed to control floods have triggered floods due to sedimentation in the
Reservoir. As dams stops natural flow of river it accumulated huge amount of sediments at its bottom which causes lower the water holding capacity and hence at time of excessive water gates of dams are required to be open causing a human aid to the magnitude of flood.
Q2) Write two do’s and don’t at time of flooding? Mark 2
Answer
Do’s Don’t
Use Boiled and filter drinking water Don’t use wet electrical appliances
Use bleaching power and lime to disinfect the surrounding.
Don’t enter in flooded water
Case Study 5:
Rainwater harvesting must be seamlessly integrated into the each town’s climate resilience making plans. Huge progress has absolutely been made, the evolving landscape of Delhi, wherein urbanization and climate change intersect, amplifies the urgency of water conservation. The unwavering commitment of government concerned to this motive is as a result imperative. Rainwater harvesting must be seamlessly included into the town’s weather resilience planning.”
A chronic cognizance on teaching the general public and resident welfare institutions approximately the blessings of rainwater harvesting, together with sensible implementation guidance, can cause a shift in the direction of “sustainable water practices”. Introduction of water tariff rebates as incentives for rainwater harvesting and wastewater recycling structures serves as demonstration in their dedication to the purpose
Q1) What are the regional names given to rain water harvesting?
Answer In mountain regions people build many diversion channels knows and “kuls” and “guls”, ‘khadins’ in Jaisalmer and ‘Johads’ in other parts of Rajasthan. In Bikaner, Phalodi and Barmer, almost all the houses traditionally had underground tanks or tankas for storing drinking water.
Q2) How rainwater harvesting system works?
Answer
Step 1Rooftop rainwater is collected using a PVC pipe
Step 2 Filtered using sand and bricks
Step 3 Underground pipe takes water to sump for immediate usage
Step 4 Excess water from the sump is taken to the well
Step 5 Water from the well recharges the underground
Step 6 Take water from the well (later)
