Consider the following statement (s) related to pillars of human development.

1. Equity means making equal access to opportunities available to everybody that opportunities available to people must be equal irrespective of their gender, race, income and in the Indian case, caste.

2. Sustainability to the human labour productivity or productivity in terms of human work that must be constantly enriched by building capabilities in people.

Which is / are correct option?

Detailed Solution for Test: Class 12 Geography (India People And Economy) NCERT Based - 2 - Question 6

Components of Human Development:

1. Equality, 2. Sustainability, 3. Productivity, and 4. Empowerment.

1. Equality: If development is viewed in terms of enhancing people’s basic capabilities, people must enjoy equitable access to opportunities. Such may be called equality-related capabilities. To ensure equality-related capabilities or access to opportunities what is essential is that the societal institutional structure needs to be more favourable or progressive. In other words, the unfavourable initial asset distribution, like land, can be made more farmer-friendly through land reform and other redistributive measures. In addition, uneven income distribution may be addressed through various tax-expenditure policies.

2. Sustainability: Another important facet of human development is that development should ‘keep going’, should ‘last long’. The concept of sustainable development focuses on the need to maintain the long term protective capacity of the biosphere. This then suggests that growth cannot go on indefinitely; there are, of course, ‘limits to growth.

3. Productivity: Another component of human development is productivity which requires investment in people. This is commonly called investment in human capital. Investment in human capital—in addition to physical capital—can add more productivity.

4. Empowerment: The empowerment of people—particularly women—is another component of human development. In other words, genuine human development requires empowerment in all aspects of life. Empowerment implies a political democracy in which people themselves make the decisions about their lives. Under it, people enjoy greater political and civil liberties and remain free from excessive controls and regulations. Empowerment refers to decentralisation of power so that the benefits of governance are reaped by all peoples. It focuses on grassroots participation which promotes democracy by enfranchising the disadvantaged groups.

Which of the following types of farming is more suitable for the production of crops like sugarcane, wheat and rice?
Detailed Solution for Test: Class 12 Geography (India People And Economy) NCERT Based - 2 - Question 11

  • Irrigated farming- This type of farming is practiced in the areas where average rainfall is between 80 and 200 cms which is insufficient for certain crops. This system of farming can be practised only in those areas where availability of water from underground or surface water bodies like rivers, tanks, and lakes is sufficient throughout the year. The other condition for this farming is the availability of levelled agricultural land.

  • The main areas where much farming is practised are in Punjab, Haryana, Uttar Pradesh, north western Tamil Nadu and the deltas of peninsular rivers. The other important pockets of irrigated farming are found in the Deccan Plateau region particularly in Maharashtra, Karnataka and Andhra Pradesh. Wheat, Rice and Sugarcane are important crops of this farming.

With reference to various types of farming, which of the following is correctly matched? Types of farming Description
Detailed Solution for Test: Class 12 Geography (India People And Economy) NCERT Based - 2 - Question 12
The bases for the classification of different types of agriculture in India are rainfall, irrigational facilities, purpose of production, ownership and size of holding and technology used. On the basis of these factors a number of farming can be identified. Some of the main types of farming in India are

1. Dry Farming: This type of farming is practised in the areas where the amount of annual rainfall is generally less than 80 cms. In such regions, the farmers are generally dependent upon rainfall. Here, moisture content in the soil is less.

Hence, only one crop can be grown in a year.

2. Wet Farming: This type of farming is practised in the areas of alluvial soils where annual average rainfall is more than 200cm. Here, more than one crop is grown in a year because enough moisture in the soil is available. Rice and jute are the main crops of this type of farming. West Bengal, Assam, Nagaland, Meghalaya, Tripura, Manipur, Mizoram and Malabar Coast fall under this category of farming.

3. Irrigated Farming: This type of farming is practiced in the areas where average rainfall is between 80 and 200 cms which is insufficient for certain crops. This system of farming can be practised only in those areas where availability of water from underground or surface water bodies like rivers, tanks, and lakes is sufficient throughout the year.

4. Subsistence Farming: These types of farming are practised primarily to fulfil self-requirements of the people of the area. The main objective of this farming is to provide subsistence to the largest number of people of a given area. Size of holdings is small, use of manual labour and simple farm implements are common features of this type of farming.

5. Shifting Cultivation: In this type of cultivation land is cleared by cutting and burning of forests for raising crops. The crops are grown for a few years (2-3 years). As fertility of land declines, farmers move to new areas, clear the forests and grow crops there for next few years.

With reference to the Fallow Lands which of the following statements is incorrect?
Detailed Solution for Test: Class 12 Geography (India People And Economy) NCERT Based - 2 - Question 15

  • When lands are left unused to regain their lost fertility in a natural way is called fallow land. On the basis of usability criteria, lands can be divided into two groups current and old.

  • Current fallow is the land in which no crop is raised during the current year. Old fallow land remains unused for a period of one or more years but not exceeding 5 years.

  • This is due to low investment capacity of numerous small and marginal farmers in advanced technology, lack of awareness, loss of fertility of soil, inadequacy of rainfall, lacking in irrigational facilities etc.

  • The fallow land occupies about 7.5 per cent of the total reported area. The states of Mizoram, Tamil Nadu, Meghalaya, Bihar, Andhra Pradesh and Rajasthan have a high percentage of area under fallow land. It is to be noted here that old fallow land may not be economically important but from ecological point of view fallow land is an important category of land.

Which of the following methods is suitable for conservation of water?
Detailed Solution for Test: Class 12 Geography (India People And Economy) NCERT Based - 2 - Question 18
We can do conservation of water by using various methods such as reforestation, re-use, recycle, increase water use efficiency, water harvesting and ground water recharge.

1. Reforestation: There is a continuous interchange of moisture between earth and atmosphere, constituting the hydrological cycle. The movement of water through the hydrological cycle has a major influence on rainfall distribution and temperature modification. Plants play an important role in the hydrological cycle through the process of transpiration. In tropical forests, 75% of the annual precipitation is returned to the atmosphere by the plants. Thus forests play a very important role in maintaining water balance of the soil and atmosphere. Forests play a protective function and conserve soil and water.

2. Recycling of water: The wastewater from industrial or domestic sources can be used after proper treatment for irrigation, recharging ground water and even for industrial and municipal use. Agricultural lands close to cities can be irrigated with municipal wastewater. Household level recycled ‘grey water’ (untreated household water which does not come in contact with toilet waste) can be used for various purposes. Grey water from showers , baths, washbasins, laundry troughs and washing machines can be put to various uses to reduce pure water requirements. Pure water after use in bath and shower can be used for watering plants.

3. Reuse of wastewater: Wastewater containing lots of nutrients.

These nutrients may help the growth of plants when such water is used in irrigation. Reuse of wastewater occurs most effectively with on-site or small treatment systems. The reuse option in the local context at the community level must be seriously considered.

4. Water harvesting: Water harvesting is collecting rainwater that falls on a house or on and around any building and then putting it to use later on or simply replenishing the ground water by allowing the water to reach underground.

5. Recharging of groundwater: The available groundwater is about 13-20 times as much as water available on the surface. The groundwater consists of water contained in the soil or aquifers (underground natural water reservoir). Rain water is the major source of water for irrigation of agricultural fields in the country and for recharging the groundwater. Rainfall is restricted to three months in a year therefore rain water should be stored and use of ground water well planned as groundwater is a renewable water source and gets replenished by natural process of recharge.

Loss of water through seepage and evaporation, water wasted on weeds, cost of bringing water from ponds to place of use should be minimized.

Which of the following factors are responsible for increasing water demand?
Detailed Solution for Test: Class 12 Geography (India People And Economy) NCERT Based - 2 - Question 19

1. Expansion of irrigation: India is an agricultural country hence plenty of water is needed for irrigation. 5.36 billion Cubic meter water was used for irrigation in the year 2000. It is 81% of the total water used. The remaining percentage (19%) of water was used for domestic, industrial and other purposes mentioned above. There has been a rapid increase in the irrigated area in India since independence. Thus the demand for irrigation in India has been increasing continuously.

2. Industrial use of water: Most industries require water at various stages of production of goods and products. Water is used in industries in both consumptive and non-consumptive ways. Be it agro-based industries (cotton, textile, jute, sugar and paper) or mineral based industries (iron, steel, chemical and cement). Water is needed in large amounts during the production process or as heat exchanger for cooling various machine parts which get heated up during the production process.

3. Rising demand for growing population: Population of India has been increasing continuously and it has increased three times since independence. Due to this increase in population, the demand for water has increased. We need water for drinking, for flushing or draining sewage or human waste, domestic use, irrigation, industries.

4. Changing lifestyle: Industrial development led to economic development. Purchasing capacity of individuals has increased. Thus the lifestyle of people changed and the standard of living has gone up. Large number of attractive appliances, gadgets and fittings for kitchen and bathroom are available in the market and people are generally tempted to use them, for example taps and showers are designed in such a way that large amounts of water come out when they are turned on.

Washing machines and dishwashers use large amounts of water but are convenient and suit the present day lifestyle.

  • Coal Bed Methane (CBM) is an unconventional form of natural gas found in coal deposits or coal seams.

  • CMB is formed during the process of coalification, the transformation of plant material into coal.It is considered a valuable energy resource with reserves and production having grown nearly every year since 1989.

  • Varied methods of recovery make CBM a stable source of energy. CBM can be recovered from underground coal before, during, or after mining operations. It can also be extracted from “unmineable” coal seams that are relatively deep, thin or of poor or inconsistent quality. Vertical and horizontal wells are used to develop CBM resources. Extraction requires drilling wells into the coal seams and removing water contained in the seam to reduce hydrostatic pressure and release absorbed (and free) gas out of the coal.

Which of the following statements is/are correct about Smelting?
Detailed Solution for Test: Class 12 Geography (India People And Economy) NCERT Based - 2 - Question 30

  • Smelting, a process by which a metal is obtained, either as the element or as a simple compound, from its ore by heating beyond the melting point, ordinarily in the presence of oxidizing agents, such as air, or reducing agents, such as coke.

  • The first metal to be smelted in the ancient Middle East was probably copper (by 5000 BCE), followed by tin, lead, and silver. To achieve the high temperatures required for smelting, furnaces with forced-air draft were developed; for iron, temperatures even higher were required.

  • Smelting thus represented a major technological achievement. In modern ore treatment, various preliminary steps are usually carried out before smelting in order to concentrate the metal ore as much as possible. In the smelting process a metal that is combined with oxygen—for example, iron oxide—is heated to a high temperature, and the oxide is caused to combine with the carbon in the fuel, escaping as carbon monoxide or carbon dioxide.
