SHORT QUESTIONS:
(1.) Why water is considered as What renewable resource?
Ans. 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.
(2.) How to revolutionise the agriculture and why?
Ans. Irrigated agriculture is the largest consumer of water. That is why,it is needed to revolutionise the agriculture through developing drought resistant crops and dry farming techniques so that requirement of water will be decreased.
(3.) What is the role of urban centers in water scarcity?
Ans. The housing societies or colonies in the cities, have their own groundwater pumping devices to meet their water needs and that leads over exploitation of water and decrease the water quality also by domestic and industrial wastes, chemicals etc.
(4) What is the main cause of water scarcity?
Ans. 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 over-exploitation, excessive use and unequal access to water among different social groups.
(5.) Why people are suffering from water scarcity when there is sufficient supply of water?
Ans. Where water is sufficiently available to meet the needs of the people, but, the area still suffers from water scarcity, this is due to bad quality of water.
(6.) What is the advantages and disadvantages of MULTI-PURPOSE RIVER PROJECTS?
Ans. There are few advantages of multi-purpose river projects such as electricity generation, water supply for irrigation, domestic and industrial uses , flood control ,recreation, inland navigation and fish breeding etc. but in long terms there are lots of disadvantages of these kind projects. These projects causing poor sediment flow ,excessive sedimentation at the bottom of the reservoir, poorer habitats for the rivers aquatic life. It was also observed that the multi-purpose projects induced earthquakes, caused water-borne diseases and pests and pollution resulting from excessive use of water.
(7.) What is dams? What are types of dams?
Ans. A dam is a barrier across flowing water that obstructs, directs or retards the flow, often creating a reservoir, lake or impoundment.
Dams are classified as timber dams, embankment dams or masonry dams, with several subtypes. According to the height, dams can be categorised as large dams and major dams or alternatively as low dams, medium height dams and high dams.
(8.) What are the effects of Regulating and damming of rivers?
Ans. Regulating and damming of rivers affect their natural flow causing poor sediment flow and excessive sedimentation at the bottom of the reservoir, resulting in rockier stream beds and poorer habitats for the rivers aquatic life.
Dams also fragment rivers making it difficult for aquatic fauna to migrate, especially for spawning.
(9.) Why the Sabarmati-basin farmers in Gujrat, were agitated?
Ans. In Gujarat, the Sabarmati-basin farmers were agitated and almost caused a riot over the higher priority given to water supply in urban areas, particularly during droughts.
(10.) What is the dispute between Karnataka, Andhra Pradesh and Maharashtra?
Ans. Krishna-Godavari dispute is due to the objections raised by Karnataka and It is regarding the diversion of more water at Koyna by the Maharashtra government for a multipurpose project. This would reduce downstream flow in their states with adverse consequences for agriculture and industry .
(11.) What is Bamboo Drip Irrigation system?
Ans. In Meghalaya, a 200-year-old system of tapping stream and spring water by using bamboo pipes, is prevalent. About 18-20 litres of water enters the bamboo pipe system, gets transported over hundreds of metres, and finally reduces to 20-80 drops per minute at the site of the plant.
BROAD QUESTIONS:
(1.) What is water scarcity? Describe the quantitative and qualitative dimensions of Water scarcity.
(2.) What is Multi-purpose river projects? Why these Multi-purpose river projects have come under great scrutiny and opposition?
(3.) Where and Why Narmada Bachao Andolan was happened?
