All living beings require water for their existence and survival. Infect without water there would be no life on the earth. The utility of water is immense: (A) It is required for domestic purposes like cooking, drinking and washing etc. (B) It is used for agriculture, pastoral industry and manufacturing industries. (C) Water is also used to harness hydro-electric power. About three-fourth of the earth’s surface is covered with water, that means there is no shortage of water. Inspire of all this most of the countries of the world are facing water crisis. This is because only a small or portion of water account for fresh water that can be put to use. The fresh water is mainly obtained from surface run off and ground water. The four’ main stages of water cycle are 1. Evaporation 2. Transpiration 3. Condensation 4. Precipitation
WATER: SOME FACTS AND FIGURES (According to the Un World water Development Report, 2003) (A) 96.5% of the total volume of world’s water is estimated to exist as oceans and only 2.5% as fresh water. Nearly 70% of this fresh water occurs as ice sheets and glaciers in Antarctica, Greenland and the mountainous region of the world while a little less than 30% is stored as stored as ground water is the world’s aquifers. (B) India receives nearly 40% of the global precipitation and ranks 133 in the would in terms of water availability per person per annum.

WATER SCARCITY Water scarcity: Shortage of water as compared to its demand is known as water scarcity. Factors responsible for water scarcity. Growing population: It is one of the basic factors which is responsible for water scarcity. Most of our cites are facing this problem due to over population - A large population means water not only for domestic use but also to produce more food. Commercialization of Agriculture: The commercial crops need more water and other inputs. Assured means of irrigation like tube wells and wells are responsible for falling ground water level. Variation in seasonal and annual precipitation: Precipitation is the main source of water in India but arrival and departure of monsoon in India is uncertain. Even the distribution of rain fall is uneven. Industrialization and Urbanization: The ever increasing number’ of industries has made matters worse by exerting pressure on existing fresh water resources. Industries apart from being heavy user of water also require power to run them. Most of our cities are over populated. Over population over utilize the water resources and also pollutes the existing resources. Over Utilization: Dot to over utilization. The water table has lowered. Pollution: Domestic waste and industrial waste are the main factors responsible for pollution of water. Need of the hour to conserve and manage the water resource. 1. To safe guard ourselves from health hazards. 2. To ensure food security. 3. Continuation of our livelihoods and productive activities. 4. Prevent degradation of our natural ecosystem. MULTI-PURPOSE RIVER PROJECTS AND INTEGRATED WATER-RESOURCES MANAGEMENT Multi purpose project: A multipurpose project is that which fulfils a variety of purposes at the same time. Example: irrigation generation of electricity etc. Main objective or Advantages of Multipurpose Project: Generation of power: They produce neat, pollution free and cheapest energy which is the back bone of industry and agriculture. According to the economic survey 2005-6 these produce more than 30,000 M.W. Power. Flood control: These projects control the flood because water can be stored in them. These project have converted many rivers of sorrow into river of boom example river kosi. Soil conservation: These conserve the soil because they slow down the speed of water. Irrigation: They irrigate the fields during the dry seasons. M;any canals have been dug and they irrigate dry areas. A forestation: Trees are systematically planted in and around reservoirs. This helps in preserving “Wild life” and natural ecosystem. Water Navigation: They provide for Inland water navigation through main river or canal. It is the cheapest means of transport for heavy goods. Fisheries: These provide ideal condition for the breeding of fish. Choosen varieties of fish are allowed to grow. Tourist Centers: These projects are well cared and are scientifically developed. So these become the centre of tourist attraction.

High Cost: The initial cost of building the dams is very high. It requires a lot of capital and engineering skills and modem machinery which is not available in India. Adverse Impact on Environment: A vast variety of flora and fauna aas well as human n settlements get submerged in the water of reservoir formed by the dam. Adverse effect on the fertility of the soil: Due to construction of dams there are no annual floods in the river. And because of this the soil of the down stream region does not get nutrient rich “slit”. This decrease the fertility of the soil. Adverse Impact on aquatic life: Dot to construction of dam on the river, the fish in the down stream area to not get sufficient nutrient material. Non-availability of water throughout the year: most of the rivers in India flow only few months. So water is not sufficient to build a dam. Disputes between different states: States have dispute over sharing of water. Height of the dam and so on. Displacement of local communities: the local people often had to give up their land and livelihood and their meager access and control over resources for the greater food of the Nation. Change in cropping pattern: They provide assured means of irrigation to farmers. Due to this most of the farmers have changed the cropping pattern shifting to water intensive and commercial crops. This has led to Stalinization of soil leading to ecological imbalance.

RAIN WATER HARVESTING
•
Rainwater Harvesting: It is a technique of increasing the recharge of ground water by capturing and storing rain water by constructing structures such as percolating pits, check dams etc. Different Techniques to conserve water: People of mountainous regions had built diversion channels like guls’ and ‘kuls’ for agriculture. Rooftop rain water have sting was commonly practiced to store drinking water. E.g. Rajasthan. In the flood plain of Bengal, people developed inundation channels to irrigate their fields. In arid and semi-arid regions, agricultural field were converted into rain fed storage structure that allowed the water to stand and moisten the soil like the ‘Khadin’s in Jaisalmer and ‘Johads in other parts of Rajasthan. Rain water Harvesting through Tanks: In the semi arid and arid region of Rajasthan particularly in phalodi, Bikaner and most of the houses, had underground tanks for storing water. These tanks were part of well developed roof top rain water harvesting system. Rain falling on the rooftops would travel down the pipe and was stored in tankers. The first spell of rain was usually not collected as this would clean the roofs and the pipes. The rain water from the subsequent showers was then collected. Importance of Rain water Harvesting: It is a reliable source of water when all other source of water dry up. It is considered the pure form of natural water. It is also given to sick people. It can be used to beat the summer heat if underground rooms adjoining the tanks are built. To meet the increasing demand. To avoid flooding of roads. To raise the ground water level. Conservation of water Resources Construction of multi-purpose project and canals.

TYPES OF AGRICULTURE IN INDIA
• (a)
Primitive subsistence Farming or Shifting Agriculture this agriculture is practiced on small patches of land with the help of primitive tools like hoe, and digging stick and family/community labour. Farming depends upon monsoons , natural fertilely of the soil and suitability of the environmental conditions. It is a slash and bum agriculture ,Farmed shifts and clear a fresh patch of land cultivation. When the soil fertility decreases, the farmers shift and clear a fresh patch of land cultivation. Nature replenishes the fertility of the soil through natural process. Farmers do not use manure, fertilizer or other modern inputs. It is known by different names in different parts of the country. (1) Jhumming –Assam, Meghalaya, Mizoram, Nagaland. (ii) Pamlou- Manipur (iii) Dipa- Bastar (Chattisgarh) and Andaman and nicobar Island. Intensive Substance Farming Fields are very small. There is intensive use of land due to high pressure of population on the agriculture land Cropping pattern is dominated by food crops. More than one crops is grown in the same field. Farmers apply modem inputs to obtain high yield. It is a labour intensive farming. Commercial Farming use of higher dose of modem inputs e.g. .HYV seeds, chemical fertilizers, insecticides and pesticides. The degree of commercialization of agriculture varies from to. e.g. Rice is commercial crop in Haryana and Punjab but in Orrisa , it is subsistence Plantation Farming It is also a type of commercial farming. A single crop is grown on a large area. It has an interface of agriculture and industry. It is done over large tracts of land using capital intensive inputs. All the products is used as raw material in respective industries. The production is mainly for market.
