Q. 1. Describe the measures of water conservation.

Ans. The following are the measures to conserve water:

1. Dams across the rivers Water conservation by making dams on the overcapacity can be increased.

2. Recycling of polluted water Today there is a technology to purify polluted water and make it drinkable. It should be put to use. The three R’s are essential in the industry. Reduce, Recycle and Reuse ie reduce water consumption, Recycle and reuse more.

3. New Devices of irrigationand installation methods should be used. Soil fertility has been made by these methods and weeds do not grow.lives.

4. Crops depending on less irrigation – DryAgriculture should be done.

5. Use of pipes in irrigation Pipes should be used instead of open drains so that water does not evaporate. 6. Interregion Transmission of Water—AvailableThrough technology, the excess water of some rivers was added to the basin of other rivers.Could 

Q. 2. Give a brief description of four methods that help in the conservation of water resources.

Ans. Conservation of natural resources should be planned so that they can be safe for the future as well. Conservation of resources like soil and minerals is particularly important. If the industrial development of the world continues at a rapid pace, then all the minerals like coal, oil, iron, etc. will get exhausted soon. While using the natural resources of an area, the needs and aspirations of the people should be kept in mind. All resources should be developed in such a way that the balanced development of the entire region can be achieved.

Being essentially dependent on only one or two types of natural resources, if their value and demand decrease or it ends, then this situation can be harmful for that area. Unplanned development of natural resources changes the economic conditions but can end and the future of human beings can be bleak. Therefore, the protection of natural resources and those resources is very important. Air, water, soil, minerals, wild animals and forests should all be protected.

1. Water should be conserved by constructing dams on big rivers, rainy rivers, by making huge artificial ponds so that its benefits can be given to mankind.

2. Water should not go waste. All the water should be used in one way or the other.

 3. Proper use and conservation of water is necessary for irrigation, hydroelectricity, industrial and domestic use and supply of drinking water.

 4. River-pond etc. area should be saved from water pollution.-

Q.3. Discuss the Ghazal Sambhar Development Programme.

Ans. Majhgawan is a village in the Satna district of Madhya Pradesh. The village was known for low productivity, lack of irrigation, receding water table, scarcity of drinking water, and soil erosion. Before 1996, there used to be acute shortage of water in the summer season. damage to agriculture used to happen People and animals lived in trouble. There was not a single tube well in the village. This village adopted the watershed scheme, digging trenches around the fields. To stop the unabated flowing water, dams were built and controlled.

Due to this the rainwater seeped into the ground and the reserves of Bhima water increased and the water level rose high. The water collected behind the earthen dams now irrigates 1504 hectares of land and people get drinking water throughout the year. The productivity of the paddy crops has increased by 52 to 60% and that of wheat by 40%.

Q. 4. Why is irrigation necessary for increasing agricultural productivity in India?

Ans. Water irrigation is very important for an agricultural country like India. Indian agriculture mainly depends on monsoon rains. Water irrigation is done by artificial means to run agriculture successfully in a state of less rainfall. The following reasons compel us to provide irrigation facilities-

1. Seasonal Rain: Monsoon rains in India occur mostly during the four months of summer. Water irrigation is necessary for agriculture in the long dry season.

 2. Uncertain RainfallAccording to uncertain. Sometimes it starts early and sometimes it rains late, it does not rain here continuously, but it happens intermittently. Crops are destroyed due to a long dry period. In some years the rainfall is normal and in some years it is very less. Famine in areas of doubtful rainfall fall. That’s why irrigation system becomes necessary.

3. Uneven distribution of rainfall — Uniform distribution of rainfall in the country is not there. Heavy rainfall occurs in many areas and is less than normal in many areas. That’s why water irrigation is very necessary for areas with insufficient rainfall.

4. Winter Crops — for Rabi crops in IndiaWater irrigation is essential.

5. Specific Crops — Regular water irrigation is necessary for the production of rice and sugarcane crops in India.

6. Production of much food grain To save the country from a food crisis, expansion of irrigation facilities is necessary to become self-sufficient in food grain production.

The success of agriculture in India depends on water irrigation means. Due to the high temperature here, crops can be grown throughout the year. In regions where there is proper arrangement of water irrigation facilities, two crops are grown in a year. The means of water irrigation are available in sufficient quantity all over the country.
