Q.4 Answer any one of the following (in about 250 words): 30

(a) What is Dumping ? Evaluate the remedial measures taken by Government of India vis- a-vis WTO provisions regarding dumping.

Important Points for Answer:

What is Dumping ?

WTO provisions

Measures by India

Answer: Dumping is a process to sell goods to foreign market at very lower prices. When production of a specified goods increases to a level where a threat is posed to the domestic market of falling prices even to the level below than the stipulated prices, the country opts to sell those goods in abroad even at a thrown away prices to save loss to its producers. But such dumping causes loss to the country where the goods are exported to. So it also takes some remedial measures to protect its domestic producers.

Generally every country opted to put some quantitative restrictions upon the dumping and also charged high income tax. But according to changed guidelines of the WTO, such restrictions are prohibited now and so no country can impose quantitative restrictions upon imports.

Due to these prohibitions, now India adopts some preventive measures which are allowed under the WTO rules. So, India gives subsidy to its farmers so that their production costs can be brought down and they can compete with imported goods. Also as second remedial measure, India imposes countervailing duties and additional charges on the goods thus imported. These charges brings the prices of the goods up and so to make them dearer.

These measures help in making the domestic industries more competitive and due to competition and enhanced technological upgradation, consumers also get cheaper goods and with good qualities.

Indian Commerce Ministry has established an organisation called ‘Directorate of Anti- Dumping’ to tackle with the issues of dumping. Main threats of dumping to India is in the spheres of agricultural produces and manufactures that are alloted to the small sector industries.

(b) Comment on the relationship between credit availability and agricultural growth in India.

Important Points for Answer:

Agriculture in India

Requirement of Credit

Relationship between credit and growth.

Answer: In India, more than 60% of population still depends upon agriculture, directly or indirectly. Most of the cultivators are landless farmers or marginal farmers. They are not able to invest enough to get more production and use technological developments for their cultivation. This is one of the main reasons why Indian agriculture has less production per hectare and why facilities of technology and irrigation cannot be utilised properly.

Credit would transform the labour intensive agriculture into capital intensive venture. It will also lead to land reforms and increase management process. Credit will also prevent post-harvest loss, it is a known fact that the Green Revolution could give result due to investment in agriculture and related technologies. The states like Punjab, Haryana, Andhra Pradesh, Maharashtra which emphasise on agriculture credit are showing growth in agriculture. They have made available credit to their farmers. On the other hand, Orissa, Uttarakhand, Jharkhand etc. have not taken proper steps to avail credit to farmers and so cannot achieve success.

In India, many sources of credits like personal credits and non-governmental credits by money lenders have clutched farmers in the net of interest that has negative impacts of agricultural growth and proper steps are required to be taken. Suicide by farmers are consequences of it.

Kisan Credit Card scheme is one of the best government scheme in this direction. Commercial and scheduled banks can be given guidelines to credit loans to farmers on softer terms, lower rate of interest and no requirements of securities etc. Proportion of credit to farmers should be increased to the total loans.

Q.7 Write about any two of the following (in about 150 words each) :    15 × 2 = 30

(a) Impact of globalisation on state system and its institutions.

Important Points for Answer:

•       Globalisation   

       Its impact on

•       State System     

       its institutions

Answer: Globalisation is a process of removing boundaries among states for the purpose of economic and cultural interaction. Countries are coming closer to each other due to globalisation and new concept of global human and global governance are emerging due to globalisation process.

State system is being greatly influenced by globalisation. States have to open their economies for this process. To develop the country, to get benefit of barrierless trade co-operative government systems are adopted. Number of trade groups and blocks are increasing. Bilateral and multilateral agreements are entered into to enhance trade. Multinational companies are coming into existence and they are getting larger and larger. WHO and IMF are organisations which are helping in the process of globalisation. Even states have to limit their sovereign decisions to such multi-lateral forums.

Also state institutions have to change their structures and organisation to get themselves accomodate with the process. Insurance, education, banks and finance, agriculture and PSUs have to make themselves more competitive, more qualitative to sustain competition given by the globalisation process.

• Main achievements

Answer: The United Nations Conference on Environment and Development, also known as the Earth Summit (or, in Portuguese, Eco ‘92) was a major conference held in Rio de Janeiro from June 3 to June 14, 1992.

178 governments participated, with 118 sending their heads of state or government. Some 2,400 representatives of non-governmental organisations (NGOs) attended, with 17,000 people at the parallel NGO Forum, who had so-called Consultative Status.

The issues addressed included :

systematic scrutiny of patterns of production—particularly the production of toxic components, such as lead in gasoline, or poisonous waste

alternative sources of energy to replace the use of fossil fuels which are linked to global climate change

new reliance on public transportation systems in order to reduce vehicle emissions, congestion in cities and the health problems caused by polluted air and smog

the growing scarcity of water

An important achievement was an agreement on the Climate Change Convention which in turn led to the Kyoto Protocol.

Another was agreement to “not carry out any activities on the lands of indigenous peoples that would cause environmental degradation or that would be culturally inappropriate”.

The Convention on Biological Diversity was opened for signature at the Earth Summit, and made a start towards redefinition of money supply measures that did not inherently encourage destruction of natural ecoregions and so-called uneconomic growth.

The Earth Summit resulted in the following documents:

Rio Declaration on Environment and Development

Q. 10 Answer any one of the following in about 250 words : 30

(a) Explain the phenomenon of ozone depletion, its causes and effects. What effects are needed to reduce it ?

Important Points for Answer:

• Ozone depletion     


• Effects       

•Efforts to reduce

Answer: Ozone Depletion : Atmosphere of the earth consists of a layer of Ozone (03) gas at the height of 30 to 60 km above the earth. This ozone layer is essential for living beings. As this layer prevents the ultraviolet (OV) rays of the sunlight coming to the earth, it protects animals and vegetation from the dangerous effect of UV rays. But due to some causes, the depletion of 03 is noticed which pose a danger to mankind as well as other forms of life.

Causes : Human activities like industrialisation and others have polluted the environment. These pollutant contains chlorofluorocarbons (CFCs) as an ingredient. These CFCs are the main elements causing depletion of Ozone layer. Chlorine, Bromine, Florine etc. halone gases are the main destroyers of 03. Due to refrigerator, plastic, paints and aerosol industries such compounds are produced. Electronics and optical industries also produce ozone destroying chemicals. UV rays separate chlorine from the CFC and this chlorine reacts with Ozone (03) and turns it into simple oxygen (02). At present USA, Europe, Chile, Australia etc. are at danger due to 03 depletion.

Effects :The Ozone depletion has various consequences dangerous to lives on the earth.

The UV can cause skin cancer and other diseases of skin. It increases temperature of the earth and therefore ice melts. This in turn raises level of the sea and may submerge the islands and the coastal areas causing damage to lives and property.

Efforts : To cope with this phenomena, international community has started efforts of reducing ozone depleting chemicals. For this, many agreements and conventions are signed. Vienna Conference of 1983, and the Montreal Protocol of 1987 are among these efforts. They prohibit production of CFCs. London Conference is also one of the important landmark in this direction. Kyoto Protocol 1997 is also related to that.

But for this, international consensus is required on technological measures. They require to develop ozone friendly technologies and to share it with other nations also.

(b) What do you understand by the term ‘biodiversity’ ? Examine the causes and consequences of degeneration of biodiversity.

Important Points for Answer:

• Biodiversity


• Consequences

Answer: Biodiversity means existence of various types of species of animals, vegetation and micro- organisms in a habitat. These diversity of living creatures make the habit, biologically diverse in resources. It contains various species, sub-species, and types. Different species and sub-species have different types of nature and qualities. These nature and qualities are exploited by mankind for his benefit and progress. For example, we use some types of vegetation for food purpose and some types of animals for transport at others for food also.

But this bio-diversity gets degenerating due to some or the other reason as narrated below :

Over exploitation of a particular type of specie gets them reduced to such a lower number to sustain.

Some species of birds are in danger due to hunting and/or loss of their natural habitats

Some animals are also on the verge of extinction because of hunting, loss of their natural  home in forests, etc.

Some species of animals and birds are used for medicinal and experimental purposes.

Some vegetations have lost their existence due to clearing of forests for mining, setting up of industries, agricultural or human dwelling purposes.

Some forests are being destroyed for urbanisation and with them gets destroyed habitation of many species of living beings.

Climate change also destroys species because some species cannot changes adapt to such changes.

Sometimes some natural calamity or sudden change in geographical set up may destroy species.


Such degeneration of biodiversity creates imbalance in the food-chain. This does not only affect the nature but also human being and their daily activities. Such changes also destroys other species dependant upon the diversity. For example, oceanic activities change chemistry of oceanic climate that destroy corals and some other organisms dependant upon them. India is one of the 12 countries with most bio-diverse area. So, naturally its economical, cultural and social activities are closely related to them. Extinction of any of them can destroy such practice. For example, the Royal Bengal Tiger, our national animal itself is at the verge of its extinction. Similarly destroying forests causes flood, reduction in precipitation and other consequences.

So, to sum up, we can say that biodiversity is a natural gift. That is getting degenerated due to mostly human activities. Such destruction must be stopped or evil consequences will follow.
