Modern adaptations of traditional rainwater harvesting method are being carried out in many parts of the country to conserve and store water. For example in Gendathur village in Mysore, Karnataka, nearly 200 households have installed the system of rainwater harvesting. Gendathur receives an annual precipitation of 1,000 mm, and with 80 per cent of collection efficiency and of about 10 fillings, every house can collect and use 50,000 litres of water annually. From the 20 houses, the net amount of rainrwater harvested annually comes to1,00,000 litres. Thus, the rainwater harvesting system is being carried out successfully in Gendathur which has earned the rare distinction of being rich in rainwater. In addition to Gendathur, tamil Nadu is the first and the only state in India which had made rooftop rainwater harvesting structure compulsory to all the houses across the state. There are legal provisions to punish the defaulters. Thus, modern adaptations of traditional rainwater harvesting methods are being carried out to conserve and store water. 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 entres 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.

Advantages and disadvantages of multi-purpose projects.
(a) Advantages:
(1) Dams built under the multi-purpose projects help to irrigate agricultural fields.
(2) Multi-purpose projects help in generation of electricity. For example, the Bhakra- Nangal project is being used both for hydel power production and irrigation.
(3) It provides water supply for industry and domestic use.
(4) It helps to control flood. For example, the Hirakud project in the Mahanadi basin integrates conservation of water with flood control.
(5) These places have become places of recreation for the people.
(6) These projects are used for inland navigation.
(7) These projects have helped in fish breeding.
(8) ln view of the above advantages, the multi-purpose projects were thought of as the vehicle that would Iead the nation to development and progress. Jawaharlal Nehru proudly proclaimed the dams as the “temples of modern India” because it would integrate development of agriculture and the village economy with rapid industrialisation and growth of the urban economy.
(b) Disadvantages:
(1) It affects the natural flow of the river causing poor sediment flow and excessive sedimentation at the bottom of the reservoir.
(2) Dams fragment rivers making it difficult for aquatic fauna to migrate, especially for spawning.
(3) The reservoirs that are created on the floodplains submerge the existing vegetation and soil leading to its decomposition over a period of time.
(4) These projects lead to large-scale displacement of local communities who have to give up their land and livelihood. This in turn led to social movements like the,Narmada Bachao Andolan’ and ‘Tehri Dam Andolan’.
(5) With irrigation facilities the farmers have changed their crops to water-intensive and commercial crops. This has great ecological consequences like salinisation of the soil.
(6) It has transformed the social landscape i.e., increased the social gap between the richer landowners and the landless poor.
(7) It has led to conflicts between people wanting different uses and benefits from the same water resources as has happened in Gujarat. Where the Sabarmati basin farmers were agitated and almost caused a riot over higher priority given to water supply in urban area, particularly during droughts.
(8) Multi-purpose projects have led to interstate water disputes that are becoming common with regard to sharing the costs and benefits of these projects.

(a) Water scarcity implies water-shortage in low rainfall regions or drought prone areas. It is related to availability of bad quality of water as well. For example, in Rajasthan we see women balancing many ‘Matkas'(earthen pots) used for collecting and storing water and travelling long distances to get water.
(b) The main causes of scarcity of water are mentioned below:
(1) Increase in population: The water scarcity is an outcome of large and growing population that needs more water for domestic use as well as to produce more food. This leads to over-exploitation of, water resources to expand irrigated areas and dry-season agriculture. More tub wells for irrigation leads to falling ground water levels, adversely affecting water availability.
(2) Intensive industrialisation: In post independent India, there has been intensive Industrialisation. More industries means need for more water and more power to run them. Thus to meet the requirement, energy is produced from hydroelectric power. Thus industrialisation has led to more consumption of water. In India, hydroelectric power contributes 22 per cent of the total electricity produced.
(3) Urbanisation: Multiplying urban centres with large and dense populations life-styles have not only added to water and energy requirements but have further aggravated the problem. People have their own groundwater pumping devices to meet their water needs. This leads to over-exploitation and depletion in the cities.
(4) Bad quality of water too leads to scarcity of water. There may be sufficient water in an area but it may be polluted by domestic and industrial wastes, chemicals, pesticides and fertilisers used in agriculture, thus, making it unsafe for human use.
(5) Unequal access to water among different social groups: Some time, the poor people in Jhuggi-Jhopri colonies may not get water for their use. The well-to-do people in-their colonies may get water. This policy of discrimination of unequal access to water leads to scarcity of water for poor people, particularly in metropolitan cities.

Water becomes a renewable resource by hydrological cycle. The freshwater which is only a small proportion of water available on earth is mainly obtained from surface run off and ground–water that is continually being renewed and recharged through the hydrological cycle. Thus, all water-precipitations, surface run off and groundwater that moves within the hydrological cycle ensures that water become a renewable resource.
