Over - Utilization of water ? Part 2.

                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 livestock and including power use is 79.6% and 13.7% water respectively. Thereafter, come domestic (3.5%) and industrial (3.3%) uses.

 In case the land area is taken up as a unit, the position could be different. By 1984-
85 the land under irrigation almost tripled to 67.5 million ha.

Environment fact

What are the scope of the environment?

Image
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. Lithosphere Biosphere:- Biosphere indicate the l...

What is natural resources and it's types?

Image
                Natural resources Natural resources are the resources which comes out from the nature to fulfill the human needs. Natural resources Natural resources is divided into two part  Renewable resources Non-renewable resources 1 . Renewable resources:- renewable resources which can renewed  along with their exploitation is known as renewable resources . Example:- soler energy ,wind energy etc Renewable resources 2. Non-renewable resources:- Non renewable resources are the resources which cannot renewed after exploitation. It take million of years to formed the resources,this type of resources is know as non renewable resources. Example :- fossil fuel etc Non renewable resources 3 cyclic resources:-resources there is no final use as they can be used continuously.  Example:- water. used in industry and domestic ways can be cleaned and used again for similar or other purpose. Such resources...

Mineral and metal production part 1.

     Production of important minerals during 1997-98 to 2001-2002 . Courtesy Research and Reference Division Ministry of Information and Broadcasting Govt. of India. M. Tonnes–Million tonnes, ’000–Tonnes-Thousand tonnes, M.C.M.–Million Cubic Metre, Kg.–Kilogram. 2. Data based on the return received under MCDR, 1998 except coal, lignite petroleum (Crude),natural gas (utilised) and minor minerals: Coal and Lignite: Coal Controller, Kolkata. Petroleum (Crude) and Natural Gas: Ministry of Petroleum & Natural Gas, New Delhi. Minor Minerals: State Governments. Environment problem created by Extracting  and minning The environment side effect of extracting and mining projects can be studied in three categories as under: Effect within and around the area covered by the dam and reservoir. Underground effects caused by emptying of area. Regional effects in terms of overall aspects inclusive of resources use and socio￾economic aspects.  It has also been participating i...
