Chapter 12: Geographical Perspective on Selected Issues and Problems
Answer: Mismanagement and environmental problem related to solid waste have now become a major problem, in India, most of the solid wastes are not collected properly. Impacts of improper management of solid wastes are. Solid wastes are a threat to human health and can cause various diseases. It creates the foul smell and it harbors flies and rodents that can cause typhoid, diphtheria, diarrhoea, malaria, cholera and other diseases. Solid waste can create inconvenience rapidly if they are not properly handled, wind and rainwater can splitted it and cause discomfort to people. Industrial solid waste can cause water pollution by dumping it into water bodies. Drains carrying untreated sewage also result in various health problems.
Q2.How do industries pollute India’s water bodies? Explain with examples.
Answer: Wastewater, poisonous gases, chemical residuals, numerous heavy metals, dust, smoke, etc from industries contribute to water pollution. During the last fifty years, the number of industries in India has grown rapidly. But water pollution is concentrated within a few subsections, mainly in the form of toxic wastes and organic pollutants. Most of these defaulting industries are leather, pulp and paper, textiles, chemicals, sugar mills, distilleries and thermal power stations. Not all industries have treatment facilities for industrial effluents. As small-scale industries cannot afford enormous investments in pollution control equipment as their profit margin is very slender.
Q3. Explain any three consequences of air pollution.
Answer: The main consequences of air pollution are as follows:
Air pollution is responsible for many diseases that cause harm to our respiratory, nervous and circulatory systems. Air pollution is responsible for creating a smoky fog over cities which is known as urban smog. It also has negative effects on human health. Air pollution is also responsible for acid rains. The first rain after summers in urban area always shows acidic nature of rainwater i.e. it shows a lower pH level than the subsequent rain.
Q4. Describe silent features of “Namami Gange program”
Ans: The Union Government has launched the ‘Namami Gange Programme’ with the following objectives:
• developing sewerage treatment systems in towns,
• monitoring of industrial effluents,
• development of river front,
• afforestation along the bank of increase biodiversity,
• cleaning of the river surface,
• development of ‘Ganga Grams’ in Uttarakhand, UP, Bihar, Jharkhand and West Bengal, and
• creating public awareness to avoid adding pollutants in to the river even in the form of rituals.
Ans: Some of the measures to minimize and control air pollution are:
– Old automobiles should be replaced by new ones, which should be redesigned in such a way that their emission cause minimum pollution.
– As coal produce poisonous gases that are released into the air, so electric engines should be used instead of steam or diesel engines.
– Maximizing afforestation on public places like along roads, in gardens around parking etc
– Newly upgraded machines will be used for smoke free emission
– Reduce our dependency on fossil fuel & encourage use of non-conventional sources of energy Like Solar energy, Wind energy etc.
– Joint effort should be made by government, NGOs & Civil societies to minimize air pollution.
– Industries should be set up at a safe distance from residential areas.
Q2. Suggest measures for reduction of land degradation.
Ans: Some measures for reduction of land degradation are:
– Watershed Management Programmes: This program maintain the balance between land, water and vegetation and attempt to improve livelihoods of the people through natural resource management and community participation. These are helpful in preventing land degradation and improving soil quality.
– Disposal of solid waste as well as liquid waste after proper treatment. If this waste is not treated properly and dumped on the land, lands get degraded.
– Convert waste into resources: Waste generated from households & from industries should be treated as resource and utilized for generating energy and compost.
– Joint participation of government, NGOs and community: There is an urgent need for joint participation of both government and people for reduction of land degradation.
– Improve Sanitary Conditions: Sanitary conditions can be improved by providing toilet facilities in Slums and other areas. Thus we can minimize land degradation in such areas.
Q3.Describe major problems of slums in India.
Answer: Slums are environmentally incompatible and degraded areas of the cities. These are occupied by the migrants who were forced to migrate from rural areas to urban areas for employment and livelihood. But because of high rent and high costs of land, they could
not afford proper housing and start to live in these areas. Major problems faced by the residents of slums are as follows:
Slums are the least choice residential areas that have broken down houses, bad hygienic conditions,
– They face various health-related problems such as malnutrition, illness and prone to various diseases.
– Dwellers are vulnerable to drug abuse, alcoholism, crime, vandalism, escapism, apathy and social exclusion because of poverty.
– Slums are overcrowded having narrow street pattern which is prone to serious hazards.
– These are the residence of less facilities like drinking water, light and toilet facilities
– poor ventilation and does not have basic facilities like drinking water, light and
– toilet, etc.
– They are not able to send their children school to provide them with education, because of a low level of income.
Air pollution is taken as addition of contaminants, like dust, fumes, gas, fog, odour, smoke or vapour to the air in substantial proportion and duration that may be harmful to flora and fauna and to property. With increasing use of varieties of fuels as the source of energy, there is a marked increase in emission of toxic gases into the atmosphere resulting in the pollution of air. Combustion of fossil fuels, mining and industries are the main sources of air pollution. These processes release oxides of sulphur and nitrogen, hydrocarbons, carbon dioxide, carbon monoxide, lead and asbestos. Air pollution causes various diseases related to respiratory, nervous and circulatory systems.
Q1.1 Is it true that air pollution causes various health related diseases?
Ans: yes, it is true that air pollution causes different diseases that are harmful for living organism. Emission of Sulphur, nitrogen, carbon monoxide, carbon dioxide, lead and asbestos may negatively harm our respiratory, nervous and circulatory systems
Q1.2 Explain main causes of air pollution. in industrial area. Explain with any one suitable example.
Ans: Use of fossil fuels in industries, vehicles & in domestic activities are the main causes air pollution.
Q1.3 Write anyone non-industrial activities, which led to air pollution
Ans: Use of firewood & cow dung for domestic activities.
Q2. Read the case/source given and answer the questions that follow by choosing the correct option.
Jhabua district is located in the westernmost agro-climatic zone in Madhya Pradesh. It is, in fact, one of the five most backward districts of the country. It is characterized by high concentration of tribal population (mostly Bhils). The people suffer due to poverty which has been accentuated by the high rate of resource degradation, both forest and land. The watershed management programmes funded by both the ministries of “Rural Development” and “Agriculture”, Government of India, have been successfully implemented in Jhabua district which has gone a long way in preventing land degradation and improving soil quality. Watershed Management Programmes acknowledge the linkage between land, water and vegetation and attempts to improve livelihoods of people through natural resource management and community participation. In the past five years, the programmes funded by the Ministry of Rural Development alone (implemented by Rajiv Gandhi Mission for Watershed Management) has treated 20 per cent of the total area under Jhabua district.
Q2.1How does watershed management may helpful to reduced land degradation
Ans: Because it contains Multi-dimensional approach i.e. prevent soil erosion, maintain forest ecology, utilize excess water for irrigation
Q2.2 land degradation may be control with joint effort of govt and community. Is it true statement?
Ans: Because government will provide assistance in different forms (i.e. financial /economical /technological help) & community has to utilize that assistance in proper manner.
Q2.3Why does Jhabua district is categories as backward
Ans: This district has low literacy level.
Lack of infra-structural development
Lack of employment opportunities.
