Question 21. Write a short note on: Urbanisation in India.
What is the impact of fast - growing cities of India on the environment and available civic amenities?
Write a brief account on the impact of rapid urbanisation in India.
Why has the rapid growth of population in the metropolitan cities of India become a serious problem? Explain any five consequences of the same.
Answer: Many causes, such as relative stagnation of agriculture in rural areas, desire of the people to get jobs in towns and cities and attraction for facilities available in urban areas or cities, have led the rural people to migrate to urban areas.
Impact of Rapid Urbanisation in Fast Growing Cities of India:
But this migration of the people from rural to urban areas is very baneful or harmful. This has led to the rapid growth of population of cities, particularly of the metropolitan cities like Delhi, Mumbai, Calcutta, Chennai etc. Such a thing has led to various problems.
(1) Impact on Agriculture- In agriculture so many hands are required both at the sowing, reaping and the harvesting time. But when people would migrate to cities, the work in the fields is bound to suffer. In such a case, we once again can be forced to beg our food from other countries.
(2) Impact on Environment- When more and more people will migrate to cities, they would naturally expand beyond limits leading to various problems. The congestion in cities would have a very bad effect on environment. Too much smoke of numerous vehicles would lead to suffocation. Not only this, the need for more land for housing would have a very bad affect on greenery. Every green field around cities would be devoured within no time resulting in ecological imbalance. Even green parts within the city is on a constant decline giving place to slums and dirty congestions.
(3) Impact on Public Facilities- Every city has a limited scope for expansion. Its roads, sewage lines, water supply etc can cope with the needs of its residents to a certain limit. But the continuous migration of rural people to nearby cities even before creation of basic amenities is ultimately destructing the city infrastructure.
(4) Problem on Slums- The continuous flow of rural people to cities is giving rise to slums. These clusters of illegal structures with no amenities for water, sewage, toilets are a great blot on the fair name of the cities.
(5) Too Much Congestion- Cities are mostly congested but when more and more people flock them they become too much congested and prone to accidents. Over-crowding adds to pollution which is both dangerous and health-hazarding.
Question 22. Why is it important to study population?
What is the purpose of studying population?
Study of population is very important because -
(1) First of all by studying population, even after ten years, tell us the exact number of people in our country only by knowing the number of people living in our country. We can know where we are going and what steps we should take to avoid the coming catastrophe as a result of the unrestricted rise of population. No county can ever think of advancing forward with the addition of so many people in its population every year. So studying population is a must for every country.
(2) Secondly, by studying population, we can know the distribution of population in our country and where more emphasis is to be laid for the development and uplift of the area.
(3) Thirdly, by studying population, we can know the sex ratio in our country and take proper steps for the welfare of the weaker sections of the society including both woman and girl-child.
(4) Fourthly, only by studying population, we can know the age composition of the people and how much burden of the dependent population (children and old people) the working population has to bear.
(5) Fifthly, it is only by studying population, we can know as to how many people are engaged in primary, secondary and tertiary occupations and what steps we should take to bring about a change in occupational structure of our country.
(6) Sixthly, it is only by studying population that we can know the level of literacy in our country and think what steps we should take to remove illiteracy from our country.
(7) Seventhly, it is only by studying the data of our population, that we can know how many adolescents (people in the age group of 10 to 19) are there in our country and what special steps we can take to bring them up so that they may prove good citizens for the country.
(8) Lastly, it is by only studying population that we can chalk out our National Population Policy and think of measures both for containing the rise of our population and take desired methods for its welfare.

Question 23. What could be the reason of uneven distribution of population in India?
What are the factors which influence the population distribution?
Answer: It is not only in India but uneven distribution of population or the varying population density is a worldwide phenomena. Population density in India varies from 904 persons per in West Bengal to only 13 persons per in Arunachal Pradesh. Following are the various reasons of uneven distribution of population in India:
(1) Geographical Factors- Favourable topography, availability of mineral and freshwater resources, favourable climate and soil fertility are some of the reasons affecting population distribution. For example, Indo-Gangetic Plains and Kerala in the South have high to very high density because of flat plains, fertile soils, abundant rains etc. States like Rajasthan, J&K, and Arunachal Pradesh etc. are sparsely populated because of unfavourable climate and topography.
(2) Social and Cultural Factors- Areas of better housing, education and health facilities are more populated. Places of religious and cultural significance also attract people. For example, Delhi, Varanasi etc.
(3) Economic Factors- Places having more industries, better transportation and communication facilities provide better employment opportunities. People from other areas migrate to these places because of the above reasons. For example- Mumbai, Bangalore, Delhi and other metropolitan cities and state like Punjab, Haryana, etc.
