Industrial Uses

The share of industrial sector is limited to 2 per cent of the surface water utilisation and 5 per cent of the ground-water. Rough estimates indicate that the present water use in the industrial sector is of the order of 15 km3 . The water use by thermal and nuclear power plants with installed capacities of 40,000 MW and 1500 MW respectively, is estimated to be about 19 km3 . The industries are needed to be switched over to water efficient technologies.

By 2050, India expects to be a major industrial power in the world. Industry needs water fresh or recycled. Processing industries depend on abundance of water. It is estimated that 64 cubic km of water will be needed by 2050 A.D. to sustain the industries. Thermal power generation needs water including a small part that is consumptive. Taking into account the electric power scenario in 2050 A.D., energy related requirement (evaporation and consumptive use) is estimated at 150 cubic km.

With the advent of globalization and privatization ,industrial activities water demands share of water is changing rapidly. In addition increase in population and rapid urbanisation also put an additional demand on water resources.

Water treatment plants for all industries emanating polluted water is the need of the hour.

Domestic Uses

The share of domestic sector is higher (9 per cent) in surface water utilisation as compared to groundwater.The National Water Policy has assigned the highest priority for drinking water supply needs followed by irrigation, hydro-power, navigation and industrial and other uses.

Million Development Goals target to halve the proportion of people without sustainable access to safe drinking water and basic sanitation by 2015. The indicators of progress towards this target are;

1) proportion of population with sustainable access to an improved drinking water source (urban and rural);

2) proportion of population with access to improved sanitation.

It is estimated that by 2050, water requirements per year for domestic use will be 90 km3 for low demand scenario and 111 km3 for high demand scenario. It is expected that about 70% of urban water requirement and 30% of rural water requirement will be met by surface water sources and the remaining from groundwater.

Irrigation is needed because of spatio-temporal variability in rainfall in the country. The large tracts of the country are deficient in rainfall and are drought prone. North-western India and Deccan plateau constitute such areas. Winter and summer seasons are more or less dry in most part of the country. Hence, it is difficult to practise agriculture without assured irrigation during dry seasons.

After independence, the Government of India gave high priority to the construction of major irrigation related infrastructure. At present, India has a capacity to store about 200 billion cubic meters of water, a gross irrigated area of about 90 million hectares 2 and an installed hydro-power capacity of about 30,000 megawatts (World Bank, 2005)

Expansion of Irrigation facilities, along with consolidation of the existing systems, has been the main part of the strategy for increasing production of food grains. With sustained and systematic development of irrigation, the irrigation potential through major, medium and minor irrigation projects has increased from 22.6 million hectares (mha.) in 1951, when the process of planning began in India, to about 98.84 mha. at the end of the year 2004-05.

 

Water is a prime natural resource, a basic human need and a precious national asset. Planning, development and management of water resources need to be governed by national perspectives.

India accounts for about 2.45 per cent of world’s surface area, 4 per cent of the world’s water resources and about 16 per cent of world’s population. The total water available from precipitation in the country in a year is about 4,000 cubic km. The availability from surface water and replenishable groundwater is 1,869 cubic km. Out of this only 60 per cent can be put to beneficial uses. Thus, the total utilisable water resource in the country is only 1,122 cubic km.

There are four main sources of water:

(i) Surface water

(ii) Underground water

(iii) Atmospheric water, and

(iv) Oceanic water

(i) Surface water

Water found on the surface is called surface water. About two – third of the total surface water flows into three major rivers of the country – Indus, Ganges and Brahmaputras. The water storage capacity of reservoirs constructed in India so far is about 17400 billion cubic metres. At the time of independence, the water storage capacity was only 180 billion cubic metres. Hence water storage capacity has increased about ten times.

India’s average annual surface run-off generated by rainfall and snowmelt is estimated to be about 1869 billion cubic meter (BCM). However, it is estimated that only about 690 BCM or 37 per cent of the surface water resources can actually be mobilised. This is because (i) over 90 per cent of the annual flow of the Himalayas rivers occur over a four month period and (ii) potential to capture such resources is complicated by limited suitable storage reservoir sites.

(ii) Underground water

It refers to all water below the water table to great depths. In the soil, both water and air coexist in the pore spaces. A profound consequence is that the capillary water in the soil can only be extracted by plant roots, within certain range of conditions. Ground water, on the other hand can be extracted by humans through wells. Ground water and soil water together constitute the lower part of the hydrological cycle. The annual potential natural of ground water recharge from rainfall in India is about 342.43 km3 , which is 8.56% of total annual rainfall of the country.

Underground water is used on a large scale in the areas where the rainfall is comparatively less. Underground water is used on a large scale in Punjab, Haryana, Rajasthan, Tamil Nadu, Gujarat and Uttar Pradesh whereas Andhra Pradesh, Madhya Pradesh, Maharashtra, Karnatake and Chhattisgarh are such states where inspite of less rainfall, the use of underground water is less. There is a great need to develop underground water resources here.

(iii) Atmospheric water

Evaporation and transpiration change liquid water into vapor, which ascends into the atmosphere due to rising air currents. Cooler temperatures aloft allow the vapor to condense into clouds and strong winds move the clouds around the world until the water falls as precipitation to replenish the earthbound parts of the water cycle. About 90 percent of water in the atmosphere is produced by evaporation from water bodies, while the other 10 percent comes from transpiration from plants.

(iv) Oceanic water

The Ocean plays a key role in this vital cycle of water. The ocean holds 97% of the total water on the planet; 78% of global precipitation occurs over the ocean, and it is the source of 86% of global evaporation. Besides affecting the amount of atmospheric water vapor and hence rainfall, evaporation from the sea surface is important in the movement of heat in the climate system. Water evaporates from the surface of the ocean, mostly in warm, cloud-free subtropical seas.

 

Rice

The rice is cultivated on the largest areas in India. Historians believe that while the indica variety of rice was first domesticated in the area covering the foothills of the Eastern Himalayas (i.e. north-eastern India).Rice is a nutritional staple food which provides instant energy as its most important component is carbohydrate (starch). Rice is grown in almost all the states of India. The main rice producing states are Tamilnadu, West Bengal, Andhra Pradesh, Bihar, Jharkhand, Uttarakhand, Chhatisgarh, Punjab, Odisha, Uttar Pradesh, Karnataka, Assam and Maharashtra. It is also grown in Haryana, Madhya Pradesh, Kerala, Gujrat and Kashmir Valley. The rice growing areas in the country can be broadly grouped into five regions as discussed below :

1. North-Eastern Region:This region comprises of Assam and North eastern states. In Assam rice is grown in the basin of Brahmnaputra river. This region receives very heavy rainfall and rice is grown under rain fed condition.
2. Eastern Region This region comprises of Bihar, Chhattisgarh, Jharkhand, Madhya Pradesh, Orissa, Eastern Uttar Pradesh and West Bengal. In this region rice is grown in the basins of Ganga and Mahanadi rivers and has the highest intensity of rice cultivation in the country. This region receives heavy rainfall and rice is grown mainly under rain fed conditions.

iii. Northern Region: This region comprises of Haryana, Punjab, Western Uttar Pradesh, Uttrakhand, Himachal Pradesh and Jammu & Kashmir. The region experiences low winter temperature and single crop of rice from May-July to September-December is grown.

1. Western Region: This region comprises of Gujarat, Maharashtra and Rajasthan. Rice is largely grown under rain fed condition during June-August to October – December.
2. Southern Region: This region comprises of Andhra Pradesh, Karnataka, Kerala and Tamil Nadu. Rice is mainly grown in deltaic tracts of Godavari, Krishna and Cauvery rivers and the non-deltaic rain fed area of Tamil Nadu and Andhra Pradesh. Rice is grown under irrigated condition in deltaic tracts.

Wheat

Wheat is the second most important food crop of India next to rice. It is a Rabi or winter crop. It is sown in the beginning of winter and harvested in the beginning of summer. Normally (in north India) the sowing of wheat begins in the month of October-November and harvesting is done in the month of March-April. This is the staple food of millions of people particularly in the northern and north-western regions of India. Unlike rice, wheat is grown mostly as a rabi or winter crop.

The main regions of wheat production in India are U.P., Punjab, Haryana, Rajasthan, Madhya Pradesh, Gujrat,Maharashtra. U.P., Punjab and Haryana together produce more than 66% of the total wheat of the country.

Cotton

 

Cotton requires a daily minimum temperature of 16ºC for germination and 21ºC to 27ºC for proper crop growth. During the fruiting phase, the day temperature ranging from 27ºC to 32ºC and cool nights are needed. The sowing season of cotton varies considerably from tract to tract and is generally early (April-May) in northern India where it is mostly irrigated. It is delayed on proceeding to down south. It is cultivated largely under rainfed or dryland conditions. An annual rainfall of atleast 50 centimetre distributed through-out the growing season is required for good yield. It is mainly raised during tropical monsoon season, although in southern India it is cultivated during late-monsoon season in winter. The cotton-picking period from mid September to November must have bright sunny days to ensure a good quality.

India has the largest area under cultivation and third largest producer of cotton next only to China and the USA. Within the country two third of total area and production is shared by four states. The main states for cotton production are Panjab, Maharashtra, Gujarat and Haryana.

Jute

Jute is a crop of humid tropical climates. It thrives well in areas with well distributed rainfall of 2,500 mm spread over vegetative growth period of the crop with no cloudiness. Locations with a mean rainfall of <1,000 mm, incessant rainfall and waterlogging are not suitable for its cultivation.

West Bengal, Bihar and Assam grow jute extensively.

Sugercane

Sugarcane belongs to the grass family. It has a thick jointed stem, Which contains the cane sugar, The juice can be taken as a drink or made into sugar, jaggery or khandsari. . The by-products of sugar are very useful. Bagasse is used to make paper, cattle feed, fuel for mills-and cardboard; molasses for power alcohol. Fertilizers, yeast and rum; and press mud of wax. and shoe polish. It supports the pesticide and fertilizer industries. Sugar factories provide employment to over a million ‘workers. India is the second largest sugarcane producer in the world.

Climatic and soil conditions which favour the cultivation of sugarcane are:-

• Temperature: 20°C-30°C. Temperature above 50°C arrests its growth and temperature below 20°C slows down its growth.
• Rain: 75-120cms. It cannot withstand frost. For ripening it needs a cool dry season.
• Soil: A medium heavy loam is ideal-In northern India it is cultivated on clay loams and alluvial soil while in south India it is cultivated on brown or reddish loams, black cotton soil and laterites.

Leading sugarcane producing states are Uttar Pradesh, Bihar, Punjab.Haryana, Maharashtra, Karnataka, Tamil Nadu, Andhra Pradesh.

Rubber

Rubber tree is sturdy, quick growing and tall. It grows on many types of soil provided the soil is deep and well drained. A warm humid equitable climate (2 1′ to 35′) and a fairly distributed rainfall of not less than 200 c m are necessary for the cultivation of rubber crop.

Kerala (accounts for 90% of the total area under rubber), Tamil Nadu, Karnataka, Andamanand Nicobar Islands. Parts of West Bengal. Orrisa., Maharashtra, Karnataka and’N.E parts of India are potential regions for rubber-cultivation.

Tea

Commercial Tea plantation in India was started by the Britishers in 1923 when wild tea plants were discovered by them in the hilly and forest areas of Assam.

Climatic conditions required for the growing of tea are

• Temp: 13-35°C. Average of 25°C is suitable.
• Humidity: – High humidity, heavy dew and morning fog promote growth if healthy leaves.
• Rainfall: Annual rainfalI (range) 150-350cm (well distributed)
• Soil- Well drained mountain soil, light, loamy, porous rich in nitrogen and iron/ laterite like the soil found in Assam

Assam is the leading producer that accounts for more than 50% of tea production of India. Tea producing areas of Assam are the hill slopes bordering the Brahmaputra and Surma valleys. West Bengal is the second largest producer of tea where tea is mostly grown in the districts of Darjeeling, Siliguri, Jalpaiguri and Cooch Bihar districts. Tamil Nadu is the third largest producer where tea growing areas are mostly restricted to Nilgiri hills.

Coffee

Commercial cultivation of coffee was started by British entrepreneurs in South India during 1820’s.

Most of India’s coffee is grown in three Southern states: Kerala, Karnataka, and Tamil Nadu, the first two account for nearly 90 percent of total production. Much of the coffee in Kerala and Karnataka is grown in the Western Ghats, a mountain chain that runs parallel to the coast line and about 100 miles inland from the Arabian Sea. India exports nearly 70 percent of the coffee it produces. These exports consist mainly of high grade beans from both the Arabica and the Robusta growing regions.

Geographical Requirement for Coffee cultivation are as follows:-

• Temperatute:- should be ranging between 15 to 28°C throughout the year. Frost free environment. Direct raysof the sun are harmfui as it.is grown in the shade of trees. In its early stages of growth it needs to be protected from hot.dry winds.
• Rainfall:- 125cm- 250 cms throughout the year.
• Soil:-. Well drained, weathered volcanic soil, red and laterite soil. The presence of humus is essential. .
• Topography:- grows on hill slopes at elevation ranging from 500mts to 1800mts.

 

Land is a finite resource. Land availability is only about 20% of the earth’s surface. Land is crucial for all developmental activities, for natural resources, ecosystem services and for agriculture. Growing population, growing needs and demands for economic development, clean water, food and other products from natural resources, as well as degradation of land and negative environmental impacts are posing increasing pressures to the land resources in many countries of the world.

India covers an area of 32,87,263 sq km. According to area size, it is the seventh largest country of the world after Russia, Canada, China, U.S.A., Brazil and Egypt. This vast size itself is the most important resource. About 30 per cent of area is covered by the mountains which are source of scenic beauty, perennial rivers, home of forests and wildlife. About 43 per cent of land area is plain which is highly suitable for agriculture. Remaining about 27 percent under plateaus is the store house of minerals and metals.

The land-use categories as maintained in the Land Revenue Records are as follows :

(i) Forests : In India, at present forest areas cover about 76.5 million hectares of land, which is about 23 per cent of the total geographical area. It ranges from about 87 per cent in Andaman & Nicobar Islands to only about 4 percent in Haryana making to range difference of 83 percent. According to our National Forest Policy, 33% of the total geographical area of the country should be under the forest cover to maintain ecological balance.

(ii) Land put to Non-agricultural Uses : Land under settlements (rural and urban), infrastructure (roads, canals, etc.), industries, shops, etc. are included in this category. An expansion in the secondary and tertiary activitieswould lead to an increase in this category of land-use.

(iii) Barren and Wastelands : The land which may be classified as a wasteland such as barren hilly terrains, desert lands, ravines, etc. normally cannot be brought under cultivation with the available technology.

(iv) Area under Permanent Pastures and Grazing Lands : Most of this type land is owned by the village ‘Panchayat’ or the Government. Only a small proportion of this land is privately owned. The land owned by the village panchayat comes under ‘Common Property Resources’.

(v) Area under Miscellaneous Tree Crops and Groves(Not included is Net sown Area) : The land under orchards and fruit trees are included in this category. Much of this land is privately owned.

(vi) Culturable Waste-Land : Any land which is left fallow (uncultivated) for more than five years is included in this category. It can be brought under cultivation after improving it through reclamation practices.

(vii) Current Fallow : This is the land which is left without cultivation for one or less than one agricultural year. Fallowing is a cultural practice adopted for giving the land rest. The land recoups the lost fertility through natural processes.

(viii) Fallow other than Current Fallow : This is also a cultivable land which is left uncultivated for more than a year but less than five years. If the land is left uncultivated for more than five years, it would be categorised as culturable wasteland. (ix) Net Area Sown : The physical extent of land on which crops are sown and harvested is known as net sown area.

 

What are natural resources ?

Natural resources are useful raw materials that we get from the Earth. They occur naturally, which means that humans cannot make natural resources. Instead, we use and modify natural resources in ways that are beneficial to us. The materials used in human-made objects are natural resources. Some examples of natural resources and the ways we can use them are:

 

Natural resources                                                                Products and services

Air                                                                                         Wind energy

Animals                                                                                Foods ( Milk, Steak, Bacon etc.),

Clothing ( wool, silk etc.

Coal                                                                                       Electricity

Minerals                                                                                Coins, wire, Steel, Aluminium etc.

INDIA : NATURAL RESOURCES

1. Land Resources: In terms of area India ranks seventh in the world with a total area of 32, 87.263 sq. km. (32.87 crore hectare). It accounts for 2.42% of total area of the world. In absolute terms India is really a big country. However, land man ratio is not favourable because of the huge population size.

Land utilisation figures are available for about 92.9% of total geographical area, that is, for 3,287.3 lakh hectare. Forest constitutes 24.01 % of the total geographical area of country. Out of a total land area of 304.2 million hectares about 170.0 million hectares is under cultivation. Food grains have preponderance in gross cropped areas as compared to non food grains. According to Agricultural Census, the area operated by large holdings (10 hectares and above) has declined and area operated under marginal holdings (less than one hectare) has increased. This indicates that land is being fragmented.

1. Forest Resources: India’s forest cover is 78.92 million hectare which is 24.01 % of the geographical area of the country. The per capita forest in India (0.5 hectare) is much less than that in the world (1.9 hectares). According to the National Policy on Forests (1988), one-third (33%) of the country’s area should be covered by forests in order to maintain ecological balance.
2. 3. Mineral Resources :

Iron-Ore: India possesses high quality iron-ore in abundance. The total reserves of iron-ore in the country are about 14.630 million tonnes of haematite and 10,619 million tonnes of magnetite. Haematite iron is mainly found in Chbattisgarh, Jharkhand, Odisha, Goa and Karnataka. The major deposit of magnetite iron is available at western coast of Karnataka. Some deposits of iron ore arc also found in Kerala, Tamil Nadu and Andhra Pradesh.

Coal reserves : India has the fifth largest coal reserves in the world. As on 31 March 2015, India had 306.6 billion metric tons (338.0 billion short tons) of the resource. The known reserves of coal rose 1.67% over the previous year, with the discovery of an estimated 5.04 billion metric tons (5.56 billion short tons). The estimated total reserves of lignite coal as on 31 March 2015 was 43.25 billion metric tons (47.67 billion short tons). The energy derived from coal in India is about twice that of the energy derived from oil, whereas worldwide, energy derived from coal is about 30% less than energy derived from oil. Coal deposits are primarily found in eastern and south-central India. Jharkhand, Odisha, Chhattisgarh, West Bengal, Madhya Pradesh, Telangana and Maharashtra accounted for 99.08% of the total known coal reserves in India. As on 31 March 2015, Jharkhand and Odisha had the largest coal deposits of 26.44% and 24.72% respectively .

The top producing states are:

• Odisha
• Chhattisgarh
• Jharkhand

Other notable coal-mining areas are as follows :

• Singarenicollieries in Bhadradi district (Old Khammam District), Telangana
• Jhariamines in Dhanbad district, Jharkhand
• Nagpur& Chandrapur district, Maharshtra
• Raniganjin Bardhaman district, West Bengal
• Neyvelilignite mines in Cuddalore district, Tamil Nadu
• Singrauli Coalfieldand Umaria Coalfield in Madhya Pradesh

 

Bauxite:

Bauxite is a main source of metal like aluminium. It is not a specific mineral but a rock consisting mainly of hydrated aluminium oxides. It is clay-like substance which is pinkish whitish or reddish in colour depending on the amount of iron content.

The total reserves of bauxite in India are estimated at 27.40 crores tonnes. The major bauxite producing states in India are Orissa, Jharkhand, Gujrat, Maharashtra, Madhya Pradesh, Karnataka, Tamil Nadu, Uttar Pradesh and Goa in a descending order of importance.

Large amount of bauxite comes from:

Orissa : Sambalpur, Koraput, Kalahandi and Ganjam,

Jharkhand : Lohardaga near Ranchi and Palamau districts,

Maharashtra: Ratnagiri and Kolaba, Thane, Satara of Kolhapur district,

Madhya Pradesh:  Chhattisgarh – Balaghat, Rajgarh and Bilashpur,

Gujarat : Bhavanagar, Junagarh and Amreli,

Karnataka: Belgaum and Bababudan hills,

Tamil Nadu: Salem.

Uranium deposits : Jaduguda in Singhbhum Thrust Belt (in the state of Jharkhand, formerly part of Bihar) is the first uranium deposit to be discovered in the country in 1951. The Singhbhum Thrust Belt (also known as Singhbhum Copper belt or Singhbhum shear Zone) is a zone of intense shearing and deep tectonization with less than 1km width and known for a number of copper deposits with associated nickel, molybdenum, bismuth, gold, silver etc. It extends in the shape of an arc for a length of about 160 km. This discovery of uranium at Jaduguda in this belt paved the way for intensive exploration work and soon a few more deposits were brought to light in this area. Some of these deposits like Bhatin, Narwapahar and Turamdih are well known uranium mines of the country. other deposits like Bagjata, Banduhurang and Mohuldih are being taken up for commercial mining operations. Some of the other areas like Garadih, Kanyaluka, Nimdih and Nandup in this belt are also known to contain limited reserves with poor grades. Apart from discoveries in the Singhbhum Thrust Belt, several uranium occurrences have also been found in Cuddapah basin of Andhra Pradesh. These include Lambapur-Peddagattu, Chitrial, Kuppunuru, Tumallapalle, Rachakuntapalle which have significantly contributed towards the uranium reserve base of India. In the Mahadek basin of Meghalaya in NorthEastern part of the country, sandsyone type uranium deposits like Domiasiat, Wahkhyn, Mawsynram provide near-surface flat orebodies amenable to commercial operations. Other areas in Rajsthan, Karnataka and Chattishgarh hold promise for developing into some major deposits.

 

 

 

 

Thorium

The IAEA’s 2005 report estimates India’s reasonably assured reserves of thorium at 319,000 tonnes, but mentions recent reports of India’s reserves at 650,000 tonnes. A government of India estimate, shared in the country’s Parliament in August 2011, puts the recoverable reserve at 846,477 tonnes. The Indian Minister of State V. Narayanasamy stated that as of May 2013, the country’s thorium reserves were 11.93 million tonnes (monazite, having 9-10% ThO₂, with a significant majority (8.59 Mt; 72%) found in the three eastern coastal states of Andhra Pradesh (3.72 Mt; 31%), Tamil Nadu (2.46 Mt; 21%) and Odisha (2.41 Mt; 20%). Both the IAEA and OECD appear to conclude that India may possess the largest share of world’s thorium deposits.

 

Iron reserves : Iron ore is a metal of universal use. It is the backbone of modern civilisation. It is the foundation of our basic industry and is used all over the world. four varieties of iron ore are generally recognized.

(i) Magnetite: This is the best quality of iron ore . It possesses magnetic property and hence is called magnetite. It is found in Andhra Pradesh, Jharkhand, Goa, Kerala, Tamil Nadu and Karnataka.

 

(ii) Haematite:

It contains 60 % to 70 % pure iron and is found in Andhra Pradesh, Jharkhand, Orissa, Chhattisgarh, Goa, Karnataka, Maharashtra and Rajasthan.

(iii) Limonite:

It contains 40 per cent to 60 per cent pure iron. It is of yellow or light brown colour. Damuda series in Raniganj coal field, Garhwal in Uttarakhand, Mirzapur in Uttar Pradesh and Kangra valley of Himachal Pradesh.

(iv) Siderite:

It contains many impurities and has just 40 to 50 per cent pure iron. However, due to presence of lime, it is self fluxing.

 

(4) Oil reserves : India had about 750 Million metric tonne of proven oil reserves as April 2014 or 5.62 billion barrels as per EIA estimate for 2009, which is the second-largest amount in the Asia-Pacific region behind China. Most of India’s crude oil reserves are located in the western coast (Mumbai High) and in the northeastern parts of the country, although considerable undeveloped reserves are also located in the offshore Bay of Bengal and in the state of Rajasthan. The combination of rising oil consumption and fairly unwavering production levels leaves India highly dependent on imports to meet the consumption needs. In 2010, India produced an average of about 33.69 million metric tonne of crude oil as on April 2010 or 877 thousand barrels per day as per EIA estimate of 2009. As of 2013 India Produces 30% of India’s resources mostly in Rajasthan.

India’s oil sector is dominated by state-owned enterprises, although the government has taken steps in past recent years to deregulate the hydrocarbons industry and support greater foreign involvement. India’s state-owned Oil and Natural Gas Corporation is the largest oil company. ONGC is the leading player in India’s upstream sector, accounting for roughly 75% of the country’s oil output during 2006, as per Indian government estimates. As a net importer of all oil, the Indian Government has introduced policies aimed at growing domestic oil production and oil exploration activities. As part of the effort, the Ministry of Petroleum and Natural Gas crafted the New Exploration License Policy (NELP) in 2000, which permits foreign companies to hold 100% equity possession in oil and natural gas projects. However, to date, only a handful of oil fields are controlled by foreign firms. India’s downstream sector is also dominated by state-owned entities, though private companies have enlarged their market share in past recent years.

The Indian Strategic Petroleum Reserve (ISPR) is an emergency fuel store of total 5 MMT (million metric tons) or 36.92 MMbbl of strategic crude oil enough to provide 10 days of consumption which are maintained by the Indian Strategic Petroleum Reserves Limited.

Strategic crude oil storages are at 3 underground locations :  in Mangalore, Visakhapatnam and Padur(nr Udupi). All these are located on the east and west coasts of India which are readily accessible to the refineries. These strategic storages are in addition to the existing storages of crude oil and petroleum products with the oil companies and serve in response to external supply disruptions .

In the 2017-18 budget speech by the Indian finance minister Arun Jaitley, it was announced that two more such caverns will be set up Chandikhole in Jajpur district of Odisha and Bikaner in Rajasthan as part of the second phase. This will take the strategic reserve capacity to 15.33 million tons.

Apart from this,India is planning to expand more strategic crude oil facilities in second phase at Rajkot in Gujarat, Padur in and Udupi district of Karnataka.

(5)  Natural gas reserves : Natural gas consists primarily of methane .Propane , butane, pentane and hexane are also present . KG basin, Assam, Gulf of Khambhat, Cuddalore district of Tamil Nadu, Barmer in Rajasthan etc. are natural gas reserves of India.

 

 

 

 

Wind energy resources : The development of wind power in India began in the 1990s, and has significantly increased in the last few years. Although a relative newcomer to the wind industry compared with Denmark or the US, domestic policy support for wind power has led India to become the country with the fourth largest installed wind power capacity in the world.

As of March 31, 2016 the installed capacity of wind power in India was 26,769.05 MW, mainly spread across Tamil Nadu (7,269.50 MW), Maharashtra (4,100.40 MW), Gujarat (3,454.30 MW), Rajasthan (2,784.90 MW), Karnataka (2,318.20 MW), Andhra Pradesh (746.20 MW) and Madhya Pradesh (423.40 MW) Wind power accounts for 14% of India’s total installed power capacity. India has set an ambitious target to generate 60,000 MW of electricity from wind power by 2022.

 

 

 

Solar power : Solar power is attractive because it is abundant and offers a solution to fossil fuel emissions and global climate change. Earth receives solar energy at the rate of approximately 1,73,000 TW. This enormously exceeds both the current annual global energy consumption rate of about 15 TW, and any conceivable requirement in the future. India is both densely populated and has high solar insolation, providing an ideal combination for solar power in India. India is already a leader in wind power generation. In solar energy sector, some large projects have been proposed, and a 35,000 km² area of the Thar Desert has been set aside for solar power projects, sufficient to generate 700 to 2,100 GW.

With about 300 clear sunny days in a year, India’s theoretical solar power reception, just on its land area, is about 5 PWh/year (i.e. = 5 trillion kWh/yr ~ 600 TW). The daily average solar energy incident over India varies from 4 to 7 kWh/m² with about 1500–2000 sunshine hours per year, depending upon location. This is far more than current total energy consumption. The India Energy Portal estimates that if 10% of the land were used for harnessing solar energy, the installed solar capacity would be at 8,000GW, or around fifty times the current total installed power capacity in the country. For example, even assuming 10% conversion efficiency for PV modules, it will still be thousand times greater than the likely electricity demand in India by the year 2015.

NTPC  Vidyut Vyapar Nigam(NVVN) ,the nodal agency for implementing the first phase of JNNSM , received 418 applications against a requirement of 650 MW(500 MW Solar Thermal and 150 MW Solar PV) for Batch I. Out of this 343 applications were for solar PV and 55 for Solar Thermal. The interest was high in the investor community for solar PV as applications worth 1715 MW (343*5 MW) were received as against a total of 150 MW. 30 bidders were selected through reverse bidding and projects were allocated to companies that offered highest discount to base tariff rate of Rs. 17.91/kWh. Projects totaling 610 MW were awarded with 145 MW under solar PV and 470 MW under Solar Thermal. The winning bids for solar PV varied from Rs. 10.95/kWh to Rs. 12.76/kWh and for Solar Thermal it was Rs. 11.14/kWh  in Phase I Batch I. Camelot Enterprises Private Ltd was the lowest bidder and other successful bidders included Mahindra Solar One, Azure Power, SunEdison Energy, Lanco Infratech.  The project capacity under Batch I is 5 MW for solar PV and minimum 5 MW and maximum 100MW for Solar Thermal. By July 2011, negotiations were concluded, PPAs awarded and financial closure achieved for 34 projects.

Under batch II, the project size has been increased up to 20 MW and the base price for solar PV projects is Rs. 15.39/kWh.  NTPC Vidyut Vyapar Nigam (NVVN) received 154 applications for 1915 MW of solar PV projects against a requirement of 350 MW. The results of the bidding for solar PV projects indicate that the grid parity for solar power may not be too far off. The winning bids varied from Rs. 7.49/kWh to Rs. 9.41/kWh. The average bid price for both batch I and II was Rs. 12.15/kWh. French project developer Solairedirect emerged as the lowest bidder and Green Infra Solar the highest bidder. The other successful bidders included companies like Welspun Solar, Azure Power, SunBorne Energy  and Mahindra Solar One. Around 70% and 85% of the allocated capacity under Phase I Batch I and Phase I Batch II respectively is to be implemented in Rajasthan.

LAND RESOURCES : UTILIZATION PATTERN IN INDIA

Land use involves the management and modification of natural environment or wilderness into built environment such as settlements and semi-natural habitats such as arable fields, pastures, and managed woods. It also has been defined as “the total of arrangements, activities, and input that people undertake in a certain land cover type.

Land is a scarce resource, whose supply is fixed for all practical purposes. At the same time, the demand for land for various competing purposes is continuously increasing with the increase in human population and economic growth.

Agricultural land: Agricultural land (also agricultural area) denotes the land suitable for agricultural production, both crops and livestock. It includes net sown area, current fallows and land under miscellaneous trees crops and groves. Agricultural land in India totals approx. 46 %  of the total geographical area in the country. This is the highest among the large and medium-sized countries of the world. This indicates The influence of favourable physical factors (like size, extent of plains and plateaus, etc.) and  The extension of cultivation to a large proportion of the cultivable land. But, because of the large population of the country, the per capita arable land (i.e. land suitable for agriculture) is low: 0.16 hectares against the world average of 0.24 hectares. About 15 per cent of the sown area is multi-cropped.

Non-agricultural land: This includes land under forests and permanent pastures, land under other non-agricultural uses (towns, villages, roads, railways, etc.) and  land classified as cultivable waste as well as barren and uncultivated land of mountain and desert areas.

 

The population continues to grow rapidly in India and great pressure is being placed on arable land resources to provide an adequate supply of food and energy requirements. Even if land resources are never exhausted, on a per capita basis they will decline significantly because they must be divided among more people. Land is one such natural resources of a nation on which the entire superstructure is created. Thus, land use is a synthesis of physical, chemical and biological systems and processes on the one hand and human/societal processes and behavior on the other hand. Land is important not only for producing food stuffs, cereals, fruits and vegetables for consumption but also for generating surpluses to meet the increasing demands created by rising population and developing industrial sector, for laying down the transport network, communication lines, for the construction of dwellings and public institutions, etc. Due to unprecedented population growth, man has made uses and misuses of land resources causing environmental degradation.

Again environmental degradation in developing countries like India, especially its manifestations in the form of soil erosion, deforestation etc, is often attributed to rapid population growth. It has however been increasingly realized that since these predominantly agricultural countries are undergoing the process of technological progress and development, many other factors also modify the relationship between population and land. Changing techniques of production, changes in the pattern of land utilization of natural as well as human resources, industrialization, urbanization, changing life styles, rising aspirations, change in consumption pattern are some of the macro level factors which make the relationship between population and land use much more complex.

The definition of function varies across the disciplines. In political science it refers to duties, in mathematics it means the relationship between two variables and in geography it is synonymous to occupation.

Geographers have classified towns on the basis of their site, situation, size, rank, location and relative elevation. Functional classification of towns attempts to categorize towns and cities according to their economic functions, thereby identifying their roles within urban systems. Most classifications use employment and occupational data. In the functional classification approach, towns are classified on the basis of their dominant function. The functional classification of towns has been illus­trated in the following paras:

1.)Administrative town

The main function of administrative cities and towns is to administer the country/state or a specific territory.It includes not only the capital cities of countries, but all the centres of provinces, states, districts and other administrative divisions of the country.

2.Defensive Towns:

During the medieval period, most of the towns and cities used to be developed on the defensive sites.Forts and garrisons used to be constructed at strategic places. The defensive towns have barracks, cantonments, and training facilities for the armed forces, airfields, and harbours for warships.Visakhapatnam, MHOW and Khadakwasla (India);

In many garrison and defensive towns, there is a clear division of land use between the civil and military authorities, so that the military installa­tions are often at a little distance from the town or are grouped together in one part of the town. This is necessary to maintain security, though often many town people are employed by the military.

3.Cultural Centres:

There are numerous towns and cities in the world, almost in each of the countries, which perform cultural functions.The cities of Oxford and Cambridge in England are the most suitable examples of educational towns. In these towns, one may find colleges, libraries, hostels, churches, playgrounds, parks and shopping centres. The environmental pollution in these towns is almost insignificant.

4.) Collection Centres:

The mining towns, fishing ports and lumbering centres fall under the category of collection centres/towns. There are numerous metallic, non-metallics, precious stones and energy resources which are obtained from mines.The towns which serve these mines may be small settlements serving a particular mine such as Zawar near Udaipur (Rajasthan), Bjiladela (Madhya Pradesh) and Digboi (Assam).They may be large in size such as Raniganj, Hazaribagh (Bihar), Ipoh in the tin rich Kinta valley of Malaysia, or Kuwait and Abadan in the oil producing regions of Kuwait and Tehran, respectively.Such towns may have some industries related to the mineral mines, such as smelters and refineries. The shops in such towns sell mining equipments and special clothes needed for miners.

5.) Production Centres:

Urban places, town and cities in which some kind of manufacturing industry is the major function is known as a production centre. The size and appearance of the town are affected by the type of industry located there.

• For example, Jamshedpur, Rourkela, Bhilai, Durgapur, Dhanbad and Bhadravati in India, Pittsburgh in USA, Magnitogorsk in Russia and Birmingham in UK are dominated by large steel plants. Such iron and steel producing towns are generally located near the coal fields.
• For the manufacturing towns, as collecting centres, transportation is very important for the transport of raw materials and the finished goods. These days such towns are generally set up on lines of communication.

In manufacturing towns, there is a segregation of houses and estab­lishments; the officer’s quarters may be grouped at one place and that of the labourers at the other.

6.) Towns of Diversified Functions:

As stated at the outset, towns are classified according to their major functions. So, all those towns (such as Mumbai, Kolkata, Chennai, etc.) can be put into a definite category in which a large number of activities are conducted. Such towns are referred as diversified in functions.

Over space and time, the functions of towns change. For example, defensive sites often become restrictive when the town expands.Thus, many towns have restricted centres which were once confined within the town walls and more extensive suburbs which grew up outside the walls or after the walls were demolished.

Shahjahanabad (old Delhi), Padova (Italy), Lahore and Rawalpindi (Pakistan), Baghdad (Iraq) and Baku (Azerbaijan) are some of the examples of such towns.

7.)Residential Towns:

In some towns, the chief function is simply to house a concentration of population. In such areas, most of the land is devoted to houses, parks and hospitals. These towns are very- well-connected with the major cities, which enables the commuters to get to work each day.

8.  Resorts:

The urban places which cater to the recreation needs of people are known as resorts or recreation towns.These urban places may be based on health-giving water (hot springs), seaside recreation, mountain climbing, cultural attractions, historical monuments, sports facilities, national parks and attractive scenery.Resorts and recreational towns have many hotels to accommodate visitors, and also provide sporting facilities such as golf courses, swimming pools, trekking and skiing. Moreover, they have numerous entertainment facilities, such as theatres, cinemas, and night clubs and children parks.

9. Transfer and Distribution Centres:

The main functions performed at transfer centres are the trade, commerce and services. Towns which are concerned with the transfer and distribution of goods, however, have trade as their major function.

They include several types of towns. For example, market towns, sea ports and financial towns.Market towns are characterized by markets, a wide range of shops, stores, warehouses, godowns, cold storages and wholesale .markets.Market towns also have banks, insurance companies and other financial organizations. Kanpur, Ahmedabad, Vadodara, Indore, Bhopal, Patna, Lucknow, Ludhiana and Hapur in India, Norwich in England, Alexandria in Egypt, and Kumasi in Ghana are some of the examples of such towns.

 

Problem of Human settlement:

Some of the major problems of urbanisation in India are

1. Urban Sprawl

Urban sprawl or real expansion of the cities, both in population and geographical area, of rapidly growing cities is the root cause of urban problems. In most cities the economic base is incapable of dealing with the problems created by their excessive size

1. Overcrowding

Overcrowding is a situation in which too many people live in too little space. Overcrowding is a logical consequence of over-population in urban areas. It is naturally expected that cities having a large size of population squeezed in a small space must suffer from overcrowding. This is well exhibited by almost all the big cities of India.

 

3.Slums and Squatter Settlements:

The natural sequel of unchecked, unplanned and haphazard growth of urban areas is the growth and spread of slums and squatter settlements which present a striking feature in the ecological structure of Indian cities, especially of metropolitan centres.

 

4.)Overcrowding

Overcrowding leads to a chronic problem of shortage of houses in urban areas. This problem is specifically more acute in those urban areas where there is large influx of unemployed or underemployed immigrants who have no place to live in when they enter cities/towns from the surrounding areas.

5.)Seweage problem

Urban areas in India are almost invariably plagued with insufficient and inefficient sewage facilities. Not a single city in India is fully sewered. Resource crunch faced by the municipalities and unauthorised growth of the cities are two major causes of this pathetic state of affairs.

 

Urban morphology is the study of the form of human settlements and the process of their formation and transformation.Morphological studies often deal with development of forms and
pattern of the present city or other urban areas through time.

Urban morphology is the study of the physical form of a city, which consists of street patterns, building sizes and shapes, architecture, population density and patterns of residential, commercial, industrial and other uses, among other things. Special attention is given to how the physical form of a city changes over time and to how different cities compare with each other.

India exhibits a very stable settlement structure such that much of the urban growth that has occurred has been because of the accretion to existing towns and settlements and only marginally because of the emergence of new towns. As a result, the proportion of urban population residing in towns above a certain population cut-off point continues to increase, but there is little evidence of correlation between city size and rates of population growth.

In other words we can state that the development of new urban centers in India has been minimal and the urban growth has been accredited to the development of existing centers.

Prof. E. Ahmad has identified some of the components of urban morphology as site characteristics, historical background, sky-line, green open spaces, and water bodies, physical and cultural dominants.

For the Census of India 2011, the definition of urban area is as follows;

1. All places with a municipality, corporation, cantonment board or notified town area committee, etc.
2. All other places which satisfied the following criteria: i) A minimum population of 5,000; ii) At least 75 per cent of the male main working population engaged in non-agricultural pursuits; and iii) A density of population of at least 400 persons per sq. km.

Urban centres of India are of 4 types:
1. Those that have grown from ancient town and villages e.g. Varansi, Madurai, Patna

2. Those that have grown from medieval towns such as Lucknow, Delhi, Jaipur. These towns have lot of features of medieval Islamic architecture with palaces, minarates, walled city with Meena bazaars.
3. Cities that have grown from the British administrative centres. Most of them were medieval towns or cantonment areas which retain lot of features of European Victorial architecture.
4. During the post independence period a number of planned cities have been developed. Chandigarh, Bhuvneshwar, Gandhinagar, Dispur and Bokaro are some of the typical examples of planned cities.

City is a complex agglomeration of multiple activities – economic, social, cultural, etc. Its ‘central area’ also known as Central Business District is its distinct section which is identified as the centre of marketing, business and financial activities as well as dense built-up sector where lines of transportation converge from various parts and nearly from all direction.

 

Settlement can be defined as any form of human habitation which ranges from a single dwelling to large city. The word settlement has another connotation as well as this is a process of opening up and settling of a previously uninhabited area by the people. In geography this process is also known as occupancy.

Settlements can broadly be divided into two types – rural and urban. Before discussing about meaning and types of rural and urban settlement in India, we should know some basic differences between rural and urban areas in general. (i) The major difference between rural and urban areas is the function. Rural areas have predominantly primary activities, whereas urban areas have domination of secondary and tertiary activities. (ii) Generally the rural areas have low density of population than urban.

Types of Rural Settlements:

Geographers have suggested various schemes of classification. If we group settlements found all over the country, these can broadly be grouped under four categories:

1. Compact/clustered/nucleated settlement
2. Semi-compact/Semi-clustered/fragmented settlement
3. Hemleted settlement
4. Dispersed settlement

 

Compact Settlements:

• As the name suggests, these settlements have closely built up area. Therefore in such settlements all the dwellings are concentrated in one central sites and these inhabited area is distinct and separated from the farms and pastures.
• Maximum settlements of our country comes under this category. They are spread over almost every part of the country.
• These settlements are distributed over the entire northern Indo-Ganga plain (from Punjab in the north-west to West Bengal in the east), Orissa coast, basins of Mahanadi in Chhattisgarh, coastal areas of Andhra Pradesh, cauvery delta of Tamil Nadu, Maidaus of Karnataka, lower Assam and Tripura, in the valleys of Siwaliks etc.
• Sometimes people live in compact settlement for security or defence purpose. The greatest example of this type is in Bundelkhand region of Madhya Pradesh and Uttar Pradesh.
• In Rajasthan also people live in compact settlement because of the scarce availability of cultivable land and water body. Therefore, they want to make maximum use of available natural resources.

Semi compact Settlement:

As the name suggests, the dwellings or houses are not well-knitted. Such settlements are characterized by a small but compact nuclears around which hamlets are dispersed.

• It covers more area than the compact settlements.
• These settlements are found both in plains and plateaus depending upon the environmental conditions prevailing in that area.
• Such settlements are situated along streams in Manipur Mandla and Balaghat districts of Madhya Pradesh, and Rajgarh district of Chhattisgarh. Different tribal groups inhabit such settlements in the Chhota Nagpur region. In Nagaland, such settlements may be in the form of blushing villages.

Hamleted Settlements:

These type of settlements, are fragmented into several small units. The main settlement does not have much influence on the other units. Very often the original site is not easily distinguishable and these hamlets are often spread over the area with intervening fields. This segregation is often influenced by social and ethnic factors. The hamlets are locally named as faliya, para, dhana, dhani, nanglay etc. These settlements are generally found in West Bengal, eastern Uttar Pradesh, Madhya Pradesh and coastal plains. Geographically it covers lower Ganga plain, lower valleys of the Himalayas and central plateau or upland region of the country.

 Dispersed Settlements:

This is also known as isolated settlements. Here the settlement is characterized by units of small size which may consist of a single house to a small group of houses. It varies from two to seven huts. Therefore, in this type, hamlets are scattered over a vast area and does not have any specific pattern. Such type of settlements are found in tribal areas of central part of India covering Chhota Nagpur plateau, Madhya Pradesh, Rajasthan, etc. Such patterns are also common in the hills of north Bengal, Jammu & Kashmir, Tamil Nadu and Kerala.

 

There are three factors that influence the type of settlements in India. These factors are (i) Physical (ii) Ethnic or cultural and (iii) Historical or defence. Let us discuss these factors one by one.

Physical Factors:

These include relief, altitude, soil capability, climate, drainage, ground water level, etc. These factors influence the type and spacing of dwelling or instance, in dry regions of Rajasthan, water is a crucial factor and, therefore, houses are situated along a pond or well which guides the compactness of the settlement.

Ethnic and Cultural Factors:

These include aspects like caste, community, ethnicity and religion. In India it is commonly found that the main land owning caste resides at the centre of the village and the other service providing castes on the periphery. This leads to social segregation and fragmentation of a settlement into several units

Historical or Defence Factors:

In the past, mostly border areas of northwestern plains were conquered or attacked frequently by outsiders. For a long time, apart from attack from outsiders, there had been continuous fight between princely states and kingdom within the country therefore, security concerns favoured the evolution of nucleated settlements.

 

Type of urban settlement:

Like rural settlements, urban settlements are classified on various bases. However, classification based on size and function are most common. Let us discuss them one by one

Classification based on Population Size

According to population size, census of India classifies urban centres into six classes. Classwise urban settlements and their population

Class                              Population

Class I                            1,00,000 and above

Class II                          50,000 – 99,999

Class III                          20,000 – 49,999

Class IV                          10,000 – 19,999

Class V                            5,000 – 9,999

Class VI                          less than 5,000

 

There is another classification of urban settlements. The classification is as follows:

Town                                   Places which have less than one lakh population

City                                     Urban centres having population between one lakh to one million.

Metropolitan Cities          Cities having population in between one million to five million

Mega cities                         Cities having more than 5 million population

 

The rapid pace of population growth has led to the excessive utilization of natural resources. Huge population also leads to huge production of wastes. The resultant outcomes are loss of biodiversity, pollution of air, water and soil and increased pressure on arable land. All these have been putting great stress on the environment. If you take the case of India, it supports 17 percent of world population on just 2.4 per cent of the world land area.

The earth’s carrying capacity in terms of its food resource is approaching its limits. Oceanic supply of fish, rangelands which support livestock, and the hydrological cycle to produce freshwater are strained. The backlog of unused agricultural technology is shrinking in industrial and developing countries alike, slowing the rise in cropland productivity. At the same time, soil erosion, air pollution, soil compaction, aquifer depletion, the loss of soil organic matter, and the waterlogging and salting of irrigated land are all slowing food production. At present, it appears that nothing can reverse the worldwide decline in grain output per person. The bottomline is that the world’s farmers can no longer be counted on to feed the projected additions to the present population. Attaining a humane balance between food production and population growth now depends more on family planners instead of farmers.

Mazor impact of popuatlion growth on Environment are:

• Resource Scarcity:

– Food

– Energy (coal, oil, uranium)

– Raw materials (iron, copper, wood, water)

• Environmental Impacts

– Soil degradation

– Deforestation

– Global Warming

Population growth would not be sustainable if it has important negative impacts that will jeopardize the ability of future generations to meet their needs.

 

Rural-Urban Composition:

For the first time since Independence, the absolute increase in population is more in urban areas that in rural areas

Rural Population in India: 68.84%

Urban Population in India: 31.16%

Level of urbanization increased from 27.81% in 2001 Census to 31.16% in 2011 Census

The proportion of rural population declined from 72.19% to 68.84%

Age Structure:

 

Age- sex structure is one of the most important characteristics of population composition. Almost all population characteristics vary significantly with age.

Information is included by sex and age group (0-14 years, 15-64 years, 65 years and over). The age structure of a population affects a nation’s key socioeconomic issues. Countries with young populations (high percentage under age 15) need to invest more in schools, while countries with older populations (high percentage ages 65 and over) need to invest more in the health sector. The age structure can also be used to help predict potential political issues. For example, the rapid growth of a young adult population unable to find employment can lead to unrest.

Below is the age structure of India:

 

 

0-14 years: 27.71% (male 186,420,229/female 164,611,755)
15-24 years: 17.99% (male 121,009,850/female 106,916,692)
25-54 years: 40.91% (male 267,203,029/female 251,070,105)
55-64 years: 7.3% (male 46,398,574/female 46,105,489)
65 years and over: 6.09% (male 36,549,003/female 40,598,872) (2016 est.)

 

 

Sex Ratio:

Sex ratio is used to describe the number of females per 1000 of males. Sex ratio is a valuable source for finding the population of women in India and what is the ratio of women to that of men in India.

In the Population Census of 2011 it was revealed that the population ratio in India 2011 is 940 females per 1000 of males. The Sex Ratio 2011 shows an upward trend from the census 2001 data. Census 2001 revealed that there were 933 females to that of 1000 males.

While Kerala with sex ratio of 1084 top the list, Daman and Diu with sex ratio of 618 is at the bottom of the list.

Below is the list of states according to the sex ration. In the list we can see the states with good sex ratio.
