In the present India and whole country facing problem of food. Main cause of Food Problem are :- Quantitative aspect of food problem Qualitative aspects of food problem Distribution aspect of Food Problem Economic aspect of food problem  In Quantitative aspect of food problem are 1 .Incraeasing population :-  As we know , that nowadays ,population is increasing then demand of food will also increase . To fulfill te human need people are cutting more and more trees to grow food grains. 2. Another reason that farmer are growing  crops ,due to natural disaster it get destroyed. Due to this, price of grain rise up. Per capita net availability of food grains went up to a level of 496 grams per day in 1989 as compared to that of 395 grams in early fitfties. In 1990, it has  been provisionally estimated at 476 grams per day. In terms of gross fertilizers consumption, Indra ranks fourth in the World after USA, USSR and China. The country has the largest in the World under Pu...

                          River in india River are the source of water in which human get water. Rivers in india are classified as:- Himalay river Peninsular river  Coastal river River of inland drainage basin. Himalaya river :- The Himalayan Rivers are  the perennial river.They are generally snow-fed and have reasonable flow throughout the year. During the monsoon, the Himalayas receive very heavy rainfall and the rivers discharge the maximum quantity of water causing frequent floods. Peninsular river :-The Peninsular Rivers are generally rain-fed and therefore, fluctuate in volume. Coastal river: -A large number of the streams are Non-Perennial. The coastal streams, especially on the West Coast are short in length and have limited Catchment Areas. Most of them are flashy and non-perennial. River of inland drainage basin: -The streams of the Inland Drainage Basin, is the largest in India receivi...

                 Over -Utilization of water It  transpires from our water budget that, in case average annual rainfall of entire country and its total area are taken, the total water resources are of the order of 167 millionhectare meters. In fact, only 66 million-hectare meters of water can be utilised by us for irrigation. As there are some financial and technological constraints we plant to use it fully only by 2010 A.D. By 1951 only 9.7 million ha metre water was used for irrigation. By 1973 it was as much as 18.4 million ha metres. It is observed that Agriculture sector is the major user of water. The water used for irrigation which was two decades back nearly 40% has gone up to 73% by 2000 A.D. Irrigation use is very inefficient. Hence, 25-30% efficiency and method of irrigation are to be changed drastically. From the data on water use shown in the table given as under, it becomesevident that irrigation including for livestoc...

                  Water resources Water is very essential for human beings. Water is use for irrigation, kadigestive of food ,water is also required in large amounts for industrial and domestic consumption . Irrigation Sginificant of water  The significant of of water are:- Water is the main resource of environment. Water is also  main resources for human beings. Water need for human being for digestion of food ,  Water is also use for irrigation purpose, industry use .  Surface water   Surface water are river , lake and ponds . River River is source of water to reach to us . River water  flow takes place through 14 major river systems. They are   Brahmani,Bhrahmaputra, Cauvery, Ganga, Godavari, Indus, Krishna, Mahanadi, Mahi, ko Narmada,Periyar, Sabarmati,Subarnarekha and Tapti. Position of the river under this :- They share 83% of the drainage basin. They account for 85% of ...

Independence between environment and surrounding is that all the things are interdependent with each other . Like animal depends on each other .Just like that environment depend on the surrounding .Where the surrounding is clean . If the surrounding is clean we get the fresh air .

                          Deforestation The process of cutting down of tree in very large amount is known as deforestation. Causes of deforestation The main causes of deforestation are:- People are cutting down the tree to get more land  areas. People are leaving their cattle in field for grazing.They are destroying the whole vegetation. People are cutting down the tree for their own profit like cutting down of wood , selling in the market . People are cutting down of tree for construction building. Evil consequences of deforestation Deforestation  elegocial balance is maintained by nature break away.Floods and drought are terrible consequences. If there are so many trees present it increases the rainfall area  that fall on ground where soil observe the water .   Evil consequences of deforestation are :- 1.Adverse Effect on Productivity 2.Land/Erosion and Landslides 3.Low Per Capita...

Elements of environment Environment is constituted by the interacting systems of physical, biological and cultural elements inter-related in various ways, individually as well as collectively. These elements may be explained as under:  Physical elements Physical elements are as space, landforms, water bodies, climate soils, rocks and minerals. They determine the variable character of the human habitat, its opportunities as well as limitations.  Biological elements Biological elements such as plants, animals, microorganisms and men constitute the biosphere. Cultural elements Cultural elements such as economic, social and political elements are essentially man￾made features, which make cultural milieu.

The scope of the environment are it consist four segment Atmosphere Hydrosphere Lithosphere   Biosphere Atmosphere :- Atmosphere act as the blanket to protect from the ultraviolet ray which comes outs from the sun. On the earth it sustain life . The atmosphere is composed of nitrogen and oxygen. There are so many gases like argon ,carbon dioxide and trace gases. Hydrosphere :- Hydrosphere consist of all water bodies resources like ocean, seas ,lakes ,rivers ,glacier ground water etc. Hydrosphere In the earth 97% ,earth water supply is in oceans. About 2% water are in icecapes and glacier. Only 1% fresh water is available  in the water bodies for human consumption.   The water bodies are river ,lake and ground water. Lithosphere:- Lithosphere is the outer part of the earth .It consist of minerals occurring in earth crust and soil. example:- mineral ,organic matter ,air and water.
