One of the basic tenets of our foreign policy has been non-alignment. As an element of foreign policy non-alignment m e a n s i n d e p e n d e n t o f b l o c s , peaceful coexistence, global peace, disarmament, struggle against all manifestations of injustices like imperialism, colonialism, apartheid etc.

After India’s adoption of non-alignment as the core element of its foreign policy, it also became a model for other newly independent countries. Most of them adopted it as an instrument for independence in international relations. Soon non-alignment, in addition to a significant perspective of foreign policy, became a movement of solidarity and cooperation among the newly liberated countries of Asia, Africa and Latin America. Non-Aligned Movement (NAM) was thus founded as a solidarity movement for giving voice to Third World Countries.

Its essential purpose was to maintain equidistance in cold War rivalries and advocate principles for the promotion of world peace and cooperation. In due course of time, NAM became the largest membership movement as also the largest peace movement in the history of humanity. In both, in its founding and later consolidation and development, India played a significant role. In fact, in many ways India has been considered as a non-formal leader of the NAM.

ORIGIN OF NAM AND INDIA’S ROLE

Though as a formal organised movement NAM started with the holding of the Belgrade Summit of Non- Aligned countries in 1961, its seeds were sown by India, particularly by Jawaharlal Nehru even before attainment of India’s independence. It is quite clear that Nehru was articulating the ideas of decolonisation, national independence, non-bloc politics, peaceful coexistence, eradication of racialism and the need for the developing countries to play an active role in international affairs. It was at the initiative of Jawaharlal Nehru that India became the venue of the first forum of the liberated nations, when representatives of 28 countries met in New Delhi in March 1947 (before formal declaration of independence of India) at the Conference on Regional Cooperation among the Asian Countries known as Asian Relations Conference.

The Asian Relation Conference thus can truly be called the foundation stone for NAM.

BANDUNG CONFERENCE

Along with Nehru some other leaders in the world were also projecting these perceptions of newly independent countries. President Josip Broz Tito of Yugoslavia, President Gamel Abdul Nasser of Egypt (then called United Arab Republic), President Kwarne Nkrumah of Ghana and President Ahmed Soekarno of Indonesia were prominent among these. Together with Nehru they evolved a coherent outlook and position on Non-Alignment.

These leaders were largely instrumental in channelling the emerging changes towards the liberation of the people of the world and towards evolving a new vision of the world order. They rejected outright the notion that East- West relations alone constituted international affairs and asserted their own role in shaping these affairs. On the initiative of these leaders the conference of Afro-Asian Nations was held in Bandung (Indonesia) in April 1955.

The participants from 23 Asian and 6 African States represented mainly the people of young States which had been setup as a result of the new balance of forces of democracy and freedom on the one hand and of colonialism and oppression on the others. The states participating in the conference did not belong to any military or political blocs, arid they had taken clear and definite positions the problems facing mankind. Despite their different perspectives, the countries represented at the Bandung Conference arrived at a common position in the larger interest of world peace. One of the most important achievements of the Bandung Conference was the Declaration on World Peace and Cooperation. This declaration embodied the principles of Panchsheel which were first stated in the Preamble to the agreement between India and China in April 1954.

INDIA’S PIVOTAL ROLE AT NAM

It is quite clear that in the founding of NAM India not only played an active role as one of the founders but in many ways it was the initiator of the Movement. As we have already seen non-alignment as a concept of global politics, as a foreign policy premise and as a perspective of maximising national interest of the newly liberated countries was a vision Indian national leadership had developed during its freedom struggle itself.

The vision became the core element of India’s foreign policy after independence rand of other countries which attained independence from that period onwards.

The non-aligned movement, thus, emerged from India’s initiative for formulating an independent foreign policy. This independent foreign policy was based on a solid moral and sound political foundation. It was a non-partisan foreign policy. India’s moral approach to international politics was further projected through the Panchsheel in 1954.

Within three years, eighteen countries had endorsed the Panchsheel principles in joint communiqués with Indian leaders. These principles were practically incorporated in the Ten Principles declared at Bandung. In addition during its initial years of independence itself, India played a very active role in peaceful resolution of some complex international issues and persistently lobbied in United Nations for disarmament.

All these made the idea of non-alignment, the initial basic tenet in India’s foreign policy, a mechanism providing link between the coordinated actions of the anti- imperialist and anti-colonial forces, as an assertion of independence in foreign  affairs, as a process of weakening of power blocs, as a symbol of defiance against big power domination and as a diplomatic innovation in the phase of politics of confrontation and cold war.

Over decades of its existence the NAM has been developing a comprehensive political philosophy, a programme of action, and a new and positive system of international economic and political relations. From its founding India has remained one of the most active members of NAM and has played a pivotal role in its various activities and developments.

 

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.

2. 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.
3. 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.

NATIONAL SOLAR MISSION

 

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.

Introduction

Global energy demand continues to climb as the industrialized world’s energy use rises, millions pull themselves out of poverty in developing countries, and the world population expands. Thus, the debate over the energy supply of the future intensifies. This debate is complicated by ongoing global climate destabilization as a result of green house gas (GHG) emissions produced largely from combustion of fossil fuels (coal, oil, and natural gas) for energy. These scientific findings and economic threats have catalyzed commitments by many industrialized countries to curb GHG emissions, which in turn have created an enormous need for large-scale sources of energy alternatives to the polluting and potentially dwindling economic supplies of fossil fuels. Nuclear technology is often proposed as a solution or as part of the solution for a sustainable energy supply. In fact, the Intergovernmental Panel on Climate Change (IPCC) recommended nuclear power as a key mitigation technology that is currently commercially available. The term sustainability, however, has numerous meanings that range from the light (pale) green definitions that normally refer to near-term financial sustainability to dark green long-term multi-faceted descriptions of sustainability. Here the concept of just sustainability, which includes what has been called the equity deficit of environmental sustainability, will be used as if these requirements are met so will those of the other weaker definitions.

This conception of sustainable development focuses equally on four conditions:

• improving our quality of life and well-being
• On meeting the needs of both present and future generations (intra- and intergenerational equity)
• On justice and equity in terms of recognition, process, procedure and outcome
• On the need for us to live within ecosystem limit.

 

Advantages

• Nuclear power generation does emit relatively low amounts of CO2. Nowadays global warming because of the greenhouse gases is a hot topic. The contribution of nuclear power to global warming is relatively little. This is a great advantage of nuclear power plants. Otherwise we have to reconsider that the water used in the cooling towers produces H2O vapors, which is the number 1 greenhouse gas. H2O causes about 2/3 of the greenhouse effect. This is because of a positive feedback mechanism. If  the earth warms up, there will be more H2O vapors in the air, which reinforce the greenhouse effect.
• Nuclear power plants already exist and are available worldwide. So in comparison to, for example, nuclear fusion, the technology does not have to be developed first. Also other new technologies (wind energy, solar energy, …) are still in its infancy.

 

• Coal-fired power plants, like this one emit pollutants that can contribute to climate change, decreased air quality and acid rain. Compared to coal, nuclear power production results in very little atmospheric pollution. In 2010, massive fossil fuel emissions brought the air quality in Hong Kong dangerously low; residents were advised to remain indoors for safety. Nuclear power plants won’t create smog like this.
• While nuclear plants are somewhat expensive to build, a single facility can provide massive output for years. When this picture was taken in 2000, nuclear power accounted for almost 20 percent of all the city lights you see within the United States.
• Reliable nuclear technology is already developed. No new innovations are needed to create nuclear reactors that are relatively safe and efficient. Above, the Australian Nuclear Science and Technology Organisation opens a new research reactor in 2007.

 

Disadvantages

• Raw Material

Uranium is used in the process of fission because it’s a naturally unstable element. Unfortunately, this means that while the uranium is being mined, transported and transformed into the contained pellets used in the fission chamber it is at risk of splitting on its own. This releases harmful radiation into its surroundings, and can be harmful to those handling the material. Runoff from the uranium mines poses a dangerous health risk and possible contamination to water tables.

• Water Pollutant

Nuclear fission chambers are cooled by water. This water is then turned into steam, which is used to power the turbines. When the water cools enough to change back into liquid form, it is pumped outside into nearby wetlands. While measures are taken to ensure that no radiation is being pumped into the environment, other heavy metals and pollutants can make their way out of the chamber. The immense heat given off by this water can also be damaging to eco systems located nearby the reactor

• Radioactive Waste

One of the main worries people have about nuclear power is what to do with the radioactive waste that is generated by the reactors and secondly, what is the safety impact of storing this waste. However, even though no long-term solution has been found to eliminate the problem of waste management, the problem is much smaller than is commonly perceived. As can be seen below, the amount of deaths linked to radioactive waste over the long term are insignificant, especially when compared to the deaths caused by coal and solar power.

 

 

Deaths per 1,000 MW plant per year of operation due to waste:

One of the reasons for this low death rate is that the quantities of radioactive waste generated by a reactor are not large. In fact, the waste produced by a nuclear reactor is equivalent to the size of a coin per person, per year (Lauvergon 2003). It has even been calculated that “if the United States went completely nuclear for all its electric power for 10,000 years, the amount of land needed for waste disposal would be about what is needed for the coal ash that is currently generated every two weeks” (Cohen 1990). Worldwide, 40,000 tonnes of waste are generated annually, 15,000 tonnes being spent fuel and the 25,000 remaining tonnes, low level radioactive materials such as protective clothing or shielding (Cohen 1990).

• Reactor Safety

The reputation of nuclear power as an unsafe energy source is grossly unfair and due mainly to the Chernobyl catastrophe. It is possible to see that of all major electricity sources, nuclear is by far the source with the lowest number of fatalities, with the possible exception of renewables (for which figures aren’t available). Additionally, these figures don’t take into account premature deaths caused by pollution. If included, this would place traditional energy sources even further behind nuclear power in terms of safety.

• Proliferation Risks

The necessary raw material needed to construct a nuclear weapon is highly enriched uranium or plutonium. Enrichment technology can be used to produce highly enriched uranium. Reprocessing – certainly when the fuel has only been used in the reactor for a short time – could be used to separate out plutonium suitable for use in a nuclear weapon. International agreements have been concluded (the Nuclear Non-Proliferation Treaty and the Additional Protocol) to make trading in nuclear material and technology and the distribution of the know-how required to construct nuclear installations subject to international supervision. This means control of the peaceful use of nuclear energy technology and security of nuclear fuel. The International Atomic Energy Agency (IAEA) pursues initiatives to eventually bring all enrichment and reprocessing installations under international supervision. At the moment, the situation is not yet adequate.

• Emissions

While greenhouse gas emissions have a potential worldwide impact through global warming and climate change, SOx, NOx and particulate matters have regional or local impacts.

• Complexity in Operation

This source of energy has a load factor of 80% and future reactors will be able to produce electricity 90% of the time. This is second only to fossil fuels. However, nuclear power does face a problem. It takes 24 hours to get a plant up and running. This means that nuclear plants cannot easily adjust to fluctuating demand. This is why nuclear plants tend to be turned on constantly except during maintenance when other sources, usually fossil fuels, tend to be used to adjust for demand.

Among the risks associated with nuclear energy are the threat of terrorism and proliferation, and one point of discussion is therefore whether expansion of nuclear energy in the Netherlands would pose greater security risks than in the current situation, with only a single nuclear power station.

There are three types of terrorism threat:

• The use of explosives to disperse radioactive material; this is sometimes referred to as a “dirty bomb”. Construction of a dirty bomb does not require any material from the nuclear fuel cycle. Radioactive material is also present outside the nuclear energy sector, for example at hospitals. Security measures for the fuel cycle must therefore be aimed at preventing material falling into the hands of terrorists.
• Acquisition of a nuclear weapon by a terrorist organisation. The size and complexity of the necessary equipment means that it is no simple matter for a terrorist organisation to develop and construct a nuclear weapon. Security for nuclear installations must be aimed at minimising the risk of terrorist attacks.
• An attack on a nuclear installation, storage site, or transport of radioactive material with the intention of causing radioactive substances to be released, thus contaminating the surrounding area. Security systems that close down the reactor automatically in the event of operator error also restrict the potential threat arising from any terrorist takeover of the power station. Designers of nuclear installations and transport containers also take account of the possibility of terrorist attacks. The US Nuclear Regulatory Commission (NRC) has proposed that there should be explicit design requirements for new nuclear power stations as regards resistance to attack using an airliner.

 

Historical context

• The emergence of agricultural Price Policy in India was in the backdrop of food scarcity and price fluctuations provoked by drought, floods and international prices for exports and imports. This policy in general was directed towards ensuring reasonable food prices for consumers by providing food grains through Public Distribution System (PDS) and inducing adoption of the new technology for increasing yield by providing a price support mechanism through Minimum Support Price (MSP) system.
• In recognition of the importance of assuring reasonable produce prices to the farmers, motivating them to adopt improved technology and to promote investment by them in farm enterprises, the Agricultural Prices Commission (renamed as the Commission for Agricultural Costs and Prices in 1985) was established in 1965 for advising the Government on agricultural prices policy on a continuing basis.
• The thrust of the policy in 1965 was to evolve a balanced and integrated structure to meet the overall needs of the economy and with due regard to the interests of the producers and the consumers. The first Commission was headed by Prof M L Dantwala and in its final report the Commission suggested the Minimum Support Prices for Paddy.

 

Minimum Support Price (MSP):- is a form of market intervention by the Government of Indiato insure agricultural producers against any sharp fall in farm prices.

• The minimum support prices are announced by the Government of Indiaat the beginning of the sowing season for certain crops on the basis of the recommendations of the Commission for Agricultural Costs and Prices (CACP). 
• MSP is price fixed by Government of India to protect theproducer – farmers – against excessive fall in price during bumperproduction years.
• The minimum support prices are a guarantee price for their produce from the Government that this will be the minimum price at which their product will fetch.
• If the market price is above,MSP,the farmer can obviously sell it at the marketIn case the market price for the commodity falls below the announced minimum price due to bumper production and glut in the market,government agencies purchase the entire quantity offered by the farmers at the announced minimum price.

  The major objectives are to support the farmers from distress sales and to procure food grains for public distribution.

  As of 2015-16, Minimum support prices are currently announced for 24 commodities,which includes food grains like Wheat,paddy etc and non-food crops like raw cotton,raw jute etc.

• A pilot project under the Direct Payment Deficiency System (DPDS) for paying MSP guarantee for the cotton farmers has been initiated at Hinganghat taluka of Maharashtra in 2015. Under this system, the farmers will directly get the amount which is the difference between the Minimum Support Price (MSP) and the market price, should the market price fall below the MSP. For availing of the benefit, farmers would have to present proof of cotton sold at Agriculture Produce Market Committee yards, plus other papers such as ownership document, yield estimation and other details. If the pilot is successful, the DPDS would be rolled out in all cotton growing regions, as per the present decision. DPDS is essentially a mode of direct benefit transfer to cotton farmers.

  Then there is this concept ofPROCUREMENT PRICE, which is the price at which government procures food grains for buffer stocking and PDS purposes through FCI.

• Consider the situation where,in the wake of an imminent food shortage that may occur, the traders are willing to procure food grains in advance,driving up the market price.

 

• When the market prices are much higher than the MSP,the farmer will obviously be willing to sell it in the market.
• But the government,still, needs to procure food grains on its own to meet its distribution commitments inPDS at subsidised rates(issue price) and to create the buffer stock,necessary to intervene from supply side in case there is food deficiency and high food inflation.
• Therefore the government so as to fulfil these commitments,declares a Procurement price which is > or = to the MSP.

  The major difference between MSP and PP is that while PP is forfood grains only, MSP is for 24 crops which includes both food grains and non-food grains.

 

Method of Calculation

• In formulating the recommendations in respect of the level of minimum support prices and other non-price measures, the CACP takes into account a comprehensive view of the entire structure of the economy of a particular commodity or group of commodities.
• Other Factors include cost of production, changes in input prices, input-output price parity, trends in market prices, demand and supply, inter-crop price parity, effect on industrial cost structure, effect on cost of living, effect on general price level, international price situation, parity between prices paid and prices received by the farmers and effect on issue prices and implications for subsidy.
• The Commission makes use of both micro-level data and aggregates at the level of district, state and the country.

Supply related information – area, yield and production, imports, exports and domestic availability and stocks with the Government/public agencies or industry, cost of processing of agricultural products, cost of marketing – storage, transportation, processing, marketing services, taxes/fees and margins retained by market functionaries; etc. are also factored in.

Report of National Commission for Farmers (NCF) had recommended that MSP should be at least 50% more than the weighted average cost of production. However, this had not been accepted by the Government.
Procurement at MSP

• Farmers are made aware of the procurement operations by way of advertisements like displaying banners, pamphlets, announcement for procurement and specification in print and electronic media.
• Some States have taken steps to pre-register farmers for ensuring procurement from them through a software system.
• Keeping in view the procurement potential areas, procurement centres for MSP operations are opened by Government agencies, both Food Corporation of India (FCI) and State Government, after mutual consultations.

• Procurement centres are opened by respective State Govt. Agencies/ FCI taking into account the production, marketable surplus, convenience of farmers and availability of other logistics / infrastructure such as storage and transportation etc. Large number of temporary purchase centres in addition to the existing mandis and depots/godowns are also established at key points for the convenience of the farmers.
• The Govt. agencies also engage Co-operative Societies and Self Help Group which work as aggregators of produce from farmers and bring the produce to purchase centres being operated in particular locations/areas and increase outreach of MSP operations to small and marginal farmers. These Co-operative Societies are in addition to the direct purchases from farmers.
• Co-operative societies/Self Help Groups are engaged in many States like Bihar, Chhattisgarh, Odisha, Maharashtra, Karnataka, Jharkhand and Rajasthan. Whereas, in some states like Punjab and Haryana, the Government of India has permitted the State Governments to engage locals for procurement of food grains from the farmers on payment of commission. These steps have been taken by Government of India so that Govt. agencies can procure maximum food grains directly from farmers by expanding out- reach of MSP benefit to farmers.

• Food Corporation of India (FCI) is the designated central nodal agency for price support operations for cereals, pulses and oilseeds.

 

 

Since the grant of diwani for Bengal, Bihar and Orissa in 1765, the major concern of the East India Company’s administration in India was to collect as much revenue as possible. Agriculture was the main basis of economy and the main source of income and hence, although the nawabi administration was retained with Muhammad Reza Khan acting as the Naib Diwan for the Company, several land revenue experiments were introduced in haste to maximise extraction.

In 1772, Warren hastings  introduced a new system, known as the farming  system. European District Collectors, as the nomenclature suggested, were to be in charge of revenue collection, while the revenue collecting right was farmed out to the highest bidders. About the periodicity of the settlements, a number of experiments were made.

But the farming system ultimately failed to improve the situation, as the farmers tried to extract as much as possible without any concern for the production process. The burden of revenue demand on th peasants increased as a result and often it was so onerous that it could not be collected at all. The net outcome of this whole period of rash experimentation was the ruination of the agricultural population. In 1784, Lord Cornwallis was therefore sent to India with a specific mandate to streamline the revenue administration.

Up to 1793 A.D., The East India Company continued to follow the revenue farming system in Bengal Presidency. In 1782, Sir John Shore Committee was appointed to draft a new land revenue policy. The policy was approved by Michael Dundas, The President of Board of Control and William Pete the P.M. of England.

Permanent Settlement

The Permanent Settlement or Zamindari Sysem was introduced by Lord Corniwallis in 1793. In Bengal, North Cauvery Delta in Madras Presidency and Varanasi division. It covered altogether 19% of the total cultivable land under company rule.

Terms and Conditions of the System

• Zamindars were recognized as owner of the lands. Zamindars were given the rights to collect the rent from the peasants.
• The realized amount would be divided into 11 parts. 1/11 of the share belongs to Zamindars and 10/11 of the share belongs to East India Company.
• The Zamindars were also given Judicial powers
• The Sunset Law come into force in the event of Zamindars becoming defaulters.
• The system was introduced for a period of 10 years.

 

Effect of the system

• The effects of this system both on the zamindars and ryots were disastrous. As the revenue fixed by the system was too high, many zamindars defaulted on payments. Their property was seized and distress sales were conducted leading to their ruin. The rich zamindars who led luxurious lives left their villages and migrated into towns. They entrusted their rent collection to agents who exacted all kinds of illegal taxes besides the legal ones from the ryots.
• This had resulted in a great deal of misery amongst the peasants and farmers. Therefore Lord Cornwallis’ idea of building a system of benevolent land-lordism failed. Though initially the Company gained financially, in the long run the Company suffered financial loss because land productivity was high, income from it was meagre since it was a fixed sum. It should be noted that in pre- British period a share on the crop was fixed as land tax.

Ryotwari Settlement

The Ryotwari experiment was started by Alexander Reed in Baramahal in 1792 and was continued by Thomas Munro from 1801 when he was asked to take charge of the revenue administration of the Ceded Districts. Instead of zamindars they began to collect revenue directly from the village , fixing the amount each village had to pay. After this they proceeded to assess each cultivator or ryot separately and thus evolved the Ryotwari System. It created individual proprietary right in land, but it was vested in the peasants, rather than in the zamindars.

Effects of System

• It raised the revenue income of the government, but put the cultivators in great distress.
• In many areas no surveys were carried out and the tax of a ryot was assessed on an arbitrary basis, based on village accounts.
• The cultivating peasants were, therefore, gradually impoverished, and increasingly indebted and could not invest for the extension of cultivation.
• The Ryorwari system did not also eliminate village elites as inter mediaries between the government and the peasantry. As privileged rents and special rights of the mirasidars were recognised and caste privileges of the Brahmans respected.

Mahalwari System

Mahalwari system was introduced in 1833 during the period of William Bentick. It was introduced in Central Province, North-West Frontier, Agra, Punjab, Gangetic Valley, etc of British India.The Mahalwari system had many provisions of both the Zamindari System and Ryotwari System. In this system, the land was divided into Mahals. Each Mahal comprises one or more villages. Ownership rights were vested with the peasants. The villages committee was held responsible for collection of the taxes.

Effects of the Land Revenue Policy

• Land become a Commodity for the first time in Indian history
• Property rights in the land created for first time
• New rural classes were formed- The absentee landlords, money lenders and age earning working class.
• Commercialisation of agriculture encouraged. As a result , shortage of food crops took place causing famines. The 1832 Ganjan famine(Orissa) and 1875 deccan famine were the worst famines.
• The revenue policy was the single most important cause for all the major civilian rebellions in modern India, against the British.

 

 

 

 

Conventional and Non Conventional Sources of Energy

Main Sources of Energy:

The sources of energy are of following types:

1. Conventional Sources of Energy:

These sources of energy are also called non renewable sources. These sources of energy are in limited quantity except hydro-electric power.

(a) Coal and Lignite:

Coal is the major source of energy. Coal deposits in India are 148790 million tonnes. Total lignite reserves found at Neyveli are 3300 million tonnes. In 1950-51, annual production of coal was 32 million tonnes. In 2005-06, annual production of coal was 343 million tonnes.

Lignite production was 20.44 million tonnes in 2005-06. According to an estimate, coal reserves in India would last about 130 years. India is now the fourth largest coal producing country in the world. Coal deposits are mainly found in Orissa, Bihar, Bengal and Madhya Pradesh. It provides employment to 7 lakh workers.

(b) Oil and Natural Gas:

In India it is found in upper Assam, Mumbai High and in Gujarat. The resources of oil are small in India.

In 1950-51, the total production of oil in India was 0.3 million tonnes. It increased to 32.4 million tonnes in 2000-01. Despite tremendous increase in oil production.India still imports 70% of has oil requirements from abroad. In 1951, there was only one oil refinery in Assam.

After independence 13 such refineries were set up in public sector and their refining capacity was 604 lakh tonnes. After implementation of economic reforms, private refineries are also engaged in oil refining. As per current rate of consumption, oil reserves in India may last about 20 to 25 years.

Electricity

There are three main sources of power generation:

1. Thermal Power
2. Hydro-electric power
3. Nuclear Power
4. Thermal Power:

It is generated in India at various power stations with the help of coal and oil. It has been a major source of electric power. In 2004-05, its share in total installed capacity was 70 percent.

2. Hydro electric Power:

It is produced by constructing dams over overflowing rivers. For example BhakraNangal Project, Damodor Valley Project and Hirakund Project etc. In 1950-51, installed capacity of hydro-electricity was 587.4 MW and in 2004-05, it was 19600 MW.

3. Nuclear Power:

India has also developed nuclear power. Nuclear Power plants use uranium as fuel. This fuel is cheaper than coal. India has nuclear power plants at Tarapur, Kota (Rajasthan) Kalapakam (Chennai) Naroura (UP). Its supply accounts for only 3 percent of the total installed capacity.

POWER FROM NON CONVENTIONAL ENERGY

India is one of the fastest growing countries in terms of energy consumption. Currently, it is the fifth largest consumer of energy in the world, and will be the third largest by 2030. At the same time; the country is heavily dependent on fossil sources of energy for most of its demand. This has necessitated the country to start aggressively pursuing alternative energy sources – solar, wind, biofuels, small hydro and more.

1. Wind Energy

India‘s wind power potential has been assessed at 48500 MW. The current technical potential is estimated at about 13 000 MW, assuming 20% grid penetration, which would increase with the augmentation of grid capacity in potential states. The state-wise gross and technical potentials are given below India is implementing the world’s largest wind resource assessment program comprising wind monitoring, wind mapping and complex terrain projects.

1. Hydro Energy

Hydro power is the largest renewable energy resource being used for the generation of electricity. The 50,000 MW hydro initiatives have been already launched and are being vigorously pursued with DPRs for projects of 33,000 MW capacity already under preparation. Harnessing hydro potential speedily will also facilitate economic development of States, particularly North-Eastern States, Sikkim, Uttaranchal, Himachal Pradesh and J&K, since a large proportion of our hydro power potential islocated in these States. In India, hydro power projects with a station capacity of up to 25 megawatt (MW) each fall under the category of small hydro power (SHP).

1. Solar Energy

India is a solar rich country. India is a country near the equator – which means that given its geographical location, it is subject to a large amount of solar radiation throughout the year. India is also, according to area, the 7th largest country in the world.

The average solar radiation received by most parts of India range from about 4 to 7 kilowatt hours per meter square per day, with about 250-300 sunny days in a year. As can be seen from the solar radiation map above, the highest annual solar radiation is received by Rajasthan (desert area) and the lowest by the North eastern states of India.

1. Biomass energy

Globally, India is in the fourth position in generating power through biomass and with a huge potential, is poised to become a world leader in the utilization of biomass. Biomass power projects with an aggregate capacity of 773.3 MW through over 100 projects have been installed in the country. For the last 15 years, biomass power has become an industry attracting annual investment of over Rs. 1,000 billion, generating more than 09 billion unit of electricity per year. More than 540 million tons of crop and plantation residues are produced every year in India and a large portion is either wasted, or used inefficiently.

69. E) Energy from Wastes: The rising piles of garbage in urban areas caused by rapid urbanization and industrialization throughout India represent another source of nonconventional energy. An estimated 50 million tones of solid waste and approximately 6,000 million cubic meters of liquid waste are generated annually in the urban areas of India. Good potential exists for generating approximately 2,600 MW of power from urban and municipal wastes and approximately 1,300 MW from industrial wastes in India. A total of 48 projects with aggregate capacity of about 69.62 MWeq have been installed in the country thereby utilising only 1.8% of the potential that exists.
70. F) Biofuels: The GOI recently mandated the blending of 10 percent fuel ethanol in 90 percent gasoline. This mandate as created an approximately 3.6 billionliter demand for fuel ethanol in blend mandate to the entire country. This significant demand growth creates a tremendous manufacturing opportunity for the fuel ethanol industry seeking to expand its investments internationally

 

 

 

The thrust of the Scientific Policy Resolution, 1958 was on capacity-building in advancement of science as the foundation for making a strong nation, which had just freed itself from the shackles of colonial domination . The focus of the Technology Policy Statement, 1983 was attainment of technological self-reliance and building of national strength by reducing vulnerability in strategic areas .

The Science and Technology Policy, 2003 launched a massive programme for attracting our best talents to the arena of research in basic sciences, so that India continues to earn respect in a competitive knowledge society.

The Science, Technology and Innovation Policy (STIP), 2013 has put our science, technology an innovation (STI) system as the driver for faster, sustainable and inclusive growth .

The latest policy envisages creation of a new STI ecosystem, which finds solutions to societal problems and facilitates the entire innovation chain from knowledge to wealth creation, while at the same time attracting best students to this area, ensuring a premier position for India in the scientific world.

Investments in Science and Technology

• Global investments in science, technology and innovation are estimated at $1.2 trillion as of 2009. India’s R&D investment is less than 2.5% of this and is currently under 1 % of the GDP.
• Increasing Gross Expenditure in Research and Development (GERD) to 2% of the GDP has been a national goal for some time.
• Achieving this in the next five years is realizable if the private sector raises its R&D investment to at least match the public sector R&D investment from the current ratio of around 1 :3. The new paradigm is “Science technology and innovation for the people”.

Position in Research Publications

• The gross budgetary support for the science and technology sector has significantly increased during the last decade. The impact of such increase is becoming evident.
• India ranks ninth globally in the number of scientific publications and 12th in the number of patents filed. The Composite Annual Growth Rate (CAGR) of Indian publications is around 12±1% and India’s global share has increased from 1.8% in 2001 to 3.5% in 2011.
• But the percentage of Indian publications in the top 1 % impact making journals is only 2.5%.
• By 2020, the global share of publications must double and the number of papers in the top 1 % journals must quadruple from the current levels.

 

 Key Elements:

• Promoting the spread of scientific temper amongst all sections of society.
• Enhancing skill for applications of science among the young from all social strata.
• Making careers in science, research and innovation attractive enough for talented and bright minds.
• Establishing world class infrastructure for R&D for gaining global leadership in some select frontier areas of science.
• Positioning India among the top five global scientific powers by 2020.
• Linking contributions of science, research and innovation system with the inclusive economic growth agenda and combining priorities of excellence and relevance.
• Creating an environment for enhanced Private Sector Participation in R&D.
• Enabling conversion of R&D outputs into societal and commercial applications by replicating hitherto successful models as well as establishing of new PPP structures.
• Seeding S&T-based high-risk innovations through new mechanisms.
• Fostering resource-optimized, cost-effective innovations across size and technology domains.
• Triggering changes in the mindset and value systems to recognize, respect and reward performances which create wealth from S& T derived knowledge.
• Creating a robust national innovation system

Focus of the Policy

• Facilitating private sector investment in R&D centres in India and overseas.
• Promoting establishment of large R&D facilities in PPP mode with provisions for benefits sharing.
• Permitting multi stakeholders participation in the Indian R&D system.
• Treating R&D in the private sector at par with public institutions for availing public funds. Bench marking of R&D funding mechanisms and patterns globally.
• Modifying IPR policy to provide for marching rights for social good when supported by public funds and for co-sharing IPRs generated under PPP.
• Launching newer mechanisms for nurturing Technology Business Incubators (TBls) and science-led entrepreneurship.
• Providing incentives for commercialization of innovations with focus on green manufacturing Important Observations Policy places greater thrust on innovation, establishing research institutes and encourage women scientists with an aim to position itself among the top five scientific powers in the world by 2020.
• It talks about modifying the intellectual property regime to provide for marching rights for social good when supported by public funds and co-sharing of patents generated in the public private partnership mode.
• Aims at producing and nurturing talent in science, to stimulate research in universities, to develop young leaders in the field of science and to reward performance.
• Seeks to create a policy environment for greater private sector participation in research and innovation and to forge international alliances and collaborations to meet the national agenda.
• Talks of raising gross expenditure in R&D to two per cent of GDP from the current one per cent in this decade by encouraging enhanced private sector contribution.
• Seeks to trigger an ecosystem for innovative abilities to flourish by leveraging partnerships among diverse stakeholders and by encouraging and facilitating enterprises to invest in innovations.

 Criticism:

The policy hardly describes any structural or procedural changes which will achieve the grand goal of integrating science, technology and innovation to create value in an inclusive manner.

Forests – Natural Vegetation of India:Types and distribution

types

• Climate, soil and topographyare the major factors that influence Natural Vegetation of a place.
• The main climatic factors arerainfall and temperature. The amount of annual rainfall has a great bearing on the type of vegetation.

Annual Rainfall	Type of Vegetation
200 cm or more	Evergreen Rain Forests
100 to 200 cm	Monsoon Deciduous Forests
50 to 100 cm	Drier Deciduous or Tropical Savanna
25 to 50 cm	Dry Thorny Scrub (Semi-arid)
Below 25 cm	Desert (Arid)

• Temperature is the major factor in Himalayas and other hilly regions with an elevation of more than 900 metres.
• As the temperature falls with altitude in the Himalayan region the vegetal cover changes with altitude fromtropical to sub-tropical, temperate and finally alpine.
• Soil is an equally determining factor in few regions.Mangrove forests, swamp forests are some of the examples where soil is the major factor.
• Topography is responsible for certain minor types e.g.alpine flora, tidal forests, etc..

Moist Tropical Forests

Tropical Wet Evergreen Forests or Rain Forests

Climatic Conditions

• Annual rainfall exceeds 250 cm
• The annual temperature is about 25°-27°C
• The average annual humidity exceeds 77 per cent and
• The dry season is distinctly short.

Characteristics

• Evergreen: Due to high heat and high humidity, the trees of these forests do not shed their leaves together.
• Mesosphytic:Plants adopted to neither too dry nor too wet type climate.

What are mesophytes? ·         Unlike hydrophytic plants, such as water lily or pondweed, that grow in saturated soil or water, or xerophytic plants, such as cactus, that grow in extremely dry soil, mesophytes are ordinary plants that exist between the two extremes. ·         Mesophytic environments are marked by average to hot temperatures and soil that is neither too dry nor too wet.

• Lofty: The trees often reach 45 – 60 metres in height.
• Thick Canopy: From the air, the tropical rain forest appears like a thick canopy of foliage, broken only where it is crossed by large rivers or cleared for cultivation.
• All plants struggle upwards (mostephiphytes) for sunlight resulting in a peculiar layer arrangement. The entire morphology looks like a green carpet when viewed from above.

• Less undergrowth: The sun light cannot reach the ground due to thick canopy. The undergrowth is formed mainly of bamboos, ferns, climbers, orchids, etc.

Distribution

• Western side of the Western Ghats (500 to 1370 metres above sea level).
• Some regions in the Purvanchal hills.
• In the Andaman and Nicobar Islands.

Timber

• Hardwood: The timber of these forests is fine-grained, hard and durable.
• It has high commercial value but it is highly challenging to exploit dueto dense undergrowth, absence of pure stands and lack of transport facilities [Read previous posts on Climatic regions to understand how lumbering industry works in Equatorial Rainforests (hardwood) and Taiga Climatic (softwood) conditions].
• The important species of these forests aremahogany, mesua, white cedar, jamun, canes, bamboo 

Tropical Semi-Evergreen Forests

• They are transitional forests between tropical wet evergreen forests and tropical deciduous forests.
• They are comparatively drier areas compared to tropical wet evergreen forests.

Climatic Conditions

• Annual rainfall is 200-250 cm
• Mean annual temperature varies from 24°C to 27°C
• The relative humidity is about 75 per cent
• The dry season is not short like in tropical evergreen forests.

Distribution

• Western coast
• Assam
• Lower slopes of the Eastern Himalayas
• Odisha and

Characteristics

• The semi-evergreen forests are less dense.
• They are moregregarious [living in flocks or colonies – more pure stands] than the wet evergreen forests.
• These forests are characterized by many species.
• Trees usually havebuttressed trunks with abundant epiphytes.

Buttressed Trunks

• The important species are laurel, rosewood, mesua, thorny bamboo – Western Ghats, white cedar, Indian chestnut, champa, mango, etc. – Himalayan region.

Timber

• Hardwood: Similar to that in tropical evergreen forests except that these forests are less dense withmore pure stands (timber industry here is better than in evergreen forests).

Tropical Moist Deciduous Forests

Climatic Conditions

• Annual rainfall 100 to 200 cm.

• Andaman and Nicobar islands.

Timber

• These provide valuable timer like
• The main species found in these forests are teak, sal, laurel, rosewood, amla, jamun, bamboo, etc.
• It iscomparatively easy to exploit these forests due to their high degree of gregariousness (more pure stands).

Littoral and Swamp Forests

• They can survive and grow both in fresh as well asbrackish water(The mixture of seawater and fresh water in estuaries is called brackish water and its salinity can range from 0.5 to 35 ppt).
• Occur in and around the deltas, estuaries and creeks prone totidal influences (delta or tidal forests).
• Littoral (relating to or on the shore of the sea or a lake) forests occur at several places along the coast.
• Swamp forests are confined to the deltas of the Ganga, the Mahanadi, the Godavari, the Krishna and the Cauvery.
• Dense mangroves occur all along the coastline in sheltered estuaries, tidal creeks, backwaters, salt marshes and mudflats. It provides useful fuel wood.

Casuarina plantation ·         It resembles feathery conifer in general appearance. ·         They are rapid-growing, carefree species for sites and climates as varied as coastal sand dunes, high mountain slopes, hot humid tropics, and semi-arid regions. ·         They have the ability to fix atmospheric nitrogen. It grows 15 to 25 metres in height on an average. · · · Casuarina plantation Distribution ·         Casuarina is the most popular farm forestry in the states of Andhra Pradesh, Tamil Nadu, West Bengal, Odisha, Maharashtra, Gujarat, and Karnataka. Benefits ·         Reduces damage in the event of natural calamities. ·         Line planting in the coastal areas helps in controlling the wind force. ·         It is also used for tourism promotion in view of its ornamental appearance. ·         It provides top quality firewood. ·         The wood is suitable for paper pulp and useful raw material for the manufacture of paper for writing, printing, and wrapping. ·         It is got some serious medicinal values as well. Wasteland development ·         The characteristics which make it a suitable species for wasteland development include adaptability to wide range of habitats, fast growth, salt tolerant, drought resistant, ability to reclaim land and stabilize sand dunes. ·         Intercrops such as groundnut, cucumber, watermelons, sesamum, and pulses can also be raised along with the plantation.

Development of Hindi and Urdu Language

 

Hindi and Urdu are two Hindustani Languages; spoken mostly in the northern and Central India and in Pakistan.

Hindi and Urdu are two different languages but these languages have many common things.Both Hindi and Urdu are developed in a similar phase and adopted many changes.

We will discuss about the development of both the languages one by one.

 

Development of Hindi:

Hindi in Khariboli form has been accepted as officiallanguage of India. It is written in Devnagari script. It is listed in the 22 scheduled languages of India in our Constitution.

Hindi is one of the youngest languages of India which come in literary only before 2-3 centuries back.

Hindi is 4^ththe most speaking languages of the world after Mandarin, Spanish and English.

Now we will dig deep to find the foundation of Hindi language. Hindi is an Indo-Aryan Language which find its root in various Prakrit languages in India. There were various Prakrit was being spoken in various regions of  like Magadhi, ArdhaMagadhi, Himalayan Prakrit, ShaurseniPrakrit etc.

This was around 500-600 century than these Prakritwere developed in their regions under the patron of their rulers. Although Sanskrit was used as official communication and for literary works, yet regional languages were the languages of the masses.

 

 

Hindi language was originally calledHindvi. It started taking shape around 10^th century. It was mostly spoken in the present day Delhi. It was highly influenced by the ShaurseniAprabhansha.

The vocabulary is derived mostly from the Sanskrit Language.

We can divide the development of Hindi language in 3 stages for our understanding:

1. Early Stages
2. Middle Stage

• Modern Stage

 

1. Early Stage: This was the making time of Hindi when it was finding its root in regional Prakrit. The time can be considered form 5^th century to 1300 AD. In this time

 

1. Middle Stage: We can mark this time from 14^th century to 1800 Century. In this stage various saints and other poet wrote which was the basis of Modern day Hindi. Kabir, Ramananda, Tulsidas, Gurunanak, Meerabai , Amir Khusrau had much impact on this.

 

 

• Modern Stage: This was the time when Hindi language developed fully. A lot of development happened during this time from grammar to modern novel writing. A lot of writers and scholars have done a lot for the development of Hindi. BharatenduHarishchandra also known as father of Modern Hindi Literature; did a lot for the development of Hindi and to shape it in standardized form.

 

 

 

Development of Urdu:

The early history of Hindi and Urdu is almost same. The invasion of foreigner from western part of India from Middle East brought many changes in the Indian people. The changes was not only in culture, lifestyle but was in the language as well. The invaders patronized Persian and Arabic form of languages;which influenced the local languages and vice-versa.

Urdu is also a Hindustani language which found its origin in various other languages. Urdu is mostly spoken in the northern parts of India and is official language of some states of India. After the partition of India, Urdu was accepted as national language of Pakistan.

Urdu is developedfrom the medieval Apabhramsa of Shaurseni.

Shaurseni is an Indo-Aryan language that is also the ancestor of other modern languages, including the Punjabi and Hindi dialects.

Around 99% of Urdu verbs have their roots in Sanskrit and Prakrit.

Urdu developed under the influence of the Persian and Arabic languages, both of which have contributed a significant amount of vocabulary to formal speech.

 

The development of Urdu can be summarized in three stages:

1. Early Stage
2. Middle Stage

• Modern Stage

 

1. Early Stage: The early stage of Hindi and Urdu is almost same where it was finding its source in regional Prakrit languages. Invaders of Muslim rulers from West also brought development to initial stages. This period can be marked from 500-1300 AD.

 

1. Middle Stage: With the upcoming of Muslims rulers from west in India Persian language become prominent. Persian language itself has its roots in Arabic language. Urdu was influenced by the Perso-Arabic language duo and marked its tremendous development. Period: 1400AD -1800 AD

 

 

• Modern stage: British had played important role in developing Modern day Urdu language. Persian was the official language of many ruler’s court, British were not happy with this and they tried developing Urdu to counter Persian language. Modern writers also played an important role in development of Urdu language.
