A) With Rosmai exemples, explain in detall the uneven
Ans.
distribution of population in the world.
The population aistribution of the worla is very uneven. The population distribution and density) for the world se a whole, as well as for any part thereof, are the result of a complex of physical factors and economic conditions.
The first type of factor inoluas. cilmavo, location, and relief. It is striking fact that the overwhelming majority of the world's population lives! at low elevations; 90% or the world's people live: in areas with an elevation of less than 1,200 fast. Under certain conditione, mountains can support quite dense populations. But the limited area of cultivable land, the difficulty of working stony and poor soil are serious drawbacks to most mountain
residents, Plains offer enormous advantagea for
sedentary agriculturists. The growing season is
longer than in upland areas, soils are deeper and the yield of the land is much higher than that of mountainous terraine.
The second type of factor, influencing population' distribution and-density, includes such natural resources of the earth as water, soils, minerals, natural vegetation and animals. Though natural resources are widely distributed, many areas lack minerals in sufficient quantity and variety for major industrial developmente. Arid srea lacks rugged relier makes the cultivation of orope
difficult if not impossible. Some parts of the vet vin have few usable resources become significant only” when man employs them in providing the essentials life,
It appears certain that an all types UI economiss population distribution will continue to become more uneven; the great concentrations of population in the world will become more marked, anu the present comparatively empty areas will continue to support only a minute fraction of the world's inhabitants,
Example of a densely populated area in Monsoon Asia? India is the nation after China, the moat populous country in the world. In 1961 the population stood at 439 million and in 1963 it has reached to more 450 million and it is estimated that India accounts for one-sevanth of the world's total: population.
Even with a high death rate dus to disease, poverty and starvation, the population is increasing at a very fact rate, During the period from 1951 1961 the population has increased by 20%.
心
The huge population is creating many problema to the government. Although the average population in not very high (about 363 per square mile, England 880, Japan 688, Hong Kong 364.000), there are
overcrowding in some areas. Densities are greatest in the fertile and flat Inda-dangetic Plain as well as in the coastal lowlands in the peninsula. But in the dry interior, most of them are sparsely peopled. The distribution of population rafkects in part the major controlling factors such an soil, climate and relief conditions.
In recent years the growth in population cancells all the government's effort to improve the nation's standard of living. According to estimate, an increase in food production of at least 24 per year is needed in order to maintain the present atandard of living.

(1) Crep rotation
(ii) Izy farzing
GROP ROTATION 1—
Sell fertility can be restored without the application of fertiliser by means of this method. When a suitable rotation has been worked out it can be used indefinitely. The general idea in tha. plant foods which are taken by one type of orop are replaced by other crops. As a result, at the end of each rotation, the character and quality of the soil remain more or less unchanged.
DRY FARNING 1-
This is an attempt to prevent loss of moisture from the ground during one year, when
the land lien fallow, so that it will be added to the moisture received in the fellowing year, when- the land is cultivated. This type of farming in mainly practised in the semi-arid areas where the natural rainfall is not sufficient to grow crops. Different methods are used to check the loss of waterje.g, covering the soil with mulch of straws or plastic sheets.
