16) Merits of the Green Revolution

Green Revolution introduces a number of modern farming methods in India.

(i) Higher yield due to the use of HYV seeds.

(ii) Machines like harvesters, tractors and threshers have made ploughing and harvesting faster and easier.

(iii) Higher yield enabled farmers to sell the surplus food in the market and earn more.

(iv) Pesticides and insecticides are able to protect the crops from pests and insects.

(v) A good irrigation system is able to enhance crop production.

Demerits of the Green Revolution

(i) Loss of soil fertility due to increased use of chemical fertilisers.

(ii) Continuous use of groundwater for tubewell irrigation has reduced the water table below the ground.

(iii) The chemical fertilisers, easily soluble in water, can dissolve in the groundwater and pollute it.

(iv) They can kill bacteria and other micro-organisms helpful for the soil.

(v) Excessive use of fertilisers can also make the soil alkaline and unfit for cultivation.

17) Location

India is lying entirely in the Northern hemisphere, as shown in the figure below.

The land extends between latitudes 8°4’N and 37°6’N and longitudes 68°7’E and 97°25’E.

The Tropic of Cancer (23° 30’N) divides India into almost two equal parts.

Size

India’s total area accounts for about 2.4% of the total geographical area of the world. Thus, it is the 7th largest country in the world, by its size.

India has a land boundary of about 15,200 km.

The total length of the coastline of the mainland is 7,516.6 km including Andaman and Nicobar and Lakshadweep.

India is bounded by the mountains in the northwest, north and northeast. South of about 22° north latitude, it begins to taper and extends towards the Indian Ocean, dividing it into two seas, the Arabian Sea on the west and the Bay of Bengal on its east.

Time along the Standard Meridian of India (82°30’E) passing through Mirzapur (in Uttar Pradesh) is taken as the standard time for India.

The map below shows the Extent of India and Standard Meridian.

India and the World

The Indian landmass has a central location between the East and West Asia. India is a southward extension of the Asian continent. The trans-Indian Ocean routes connect the countries of Europe in the West and the countries of East Asia. No other country has as long a coastline on the Indian Ocean as India has. India’s contacts with the World have continued through the ages. The spices, muslin and other merchandise were taken from India to different countries. On the other hand, the influence of Greek sculpture, and the architectural styles of domes and minarets from West Asia can be seen in different parts of India.

India’s Neighbours

India has 29 states and seven Union Territories. India shares its land boundaries with:

Pakistan and Afghanistan in the northwest

China (Tibet), Nepal and Bhutan in the north

Myanmar and Bangladesh in the east

The southern neighbours across the sea consist of the two island countries, Sri Lanka and Maldives. India has had strong geographical and historical links with her neighbours.
