Agriculture
Gurpreet, Madho and Tina were walking through 
the village where they saw a farmer tilling land. The 
farmer told them that he was growing wheat and had 
just added manure to the soil to make it more fertile. 
He told the children that the wheat would fetch a 
good price in the mandi from where it would be taken 
to factories to make bread and biscuits from flour.
This transformation from a plant to a finished 
product involves three types of economic activities. 
These are primary, secondary and tertiary activities.
Primary activities include all those connected 
with extraction and production of natural resources. 
Agriculture, fishing and gathering are good examples. 
Secondary activities are concerned with the processing 
of these resources. Manufacturing of steel, baking of 
bread and weaving of cloth are examples of this activity. 
Tertiary activities provide support to the primary and 
secondary sectors through services. Transport, trade, 
banking, insurance and advertising are examples of 
tertiary activities.
Agriculture is a primary activity. It includes growing 
crops, fruits, vegetables, flowers and rearing of livestock. 
In the world, 50 per cent of persons are engaged in 
agricultural activity. Two-thirds of India’s population is 
still dependent on agriculture.
Favourable topography of soil and climate are vital 
for agricultural activity. The land on which the crops 
are grown is known as arable land (Fig. 4.1). In the map 
you can see that agricultural activity is concentrated in 
those regions of the world where suitable factors for the 
growing of crops exist.
Word Origin
The word 
agriculture is 
derived from Latin 
words ager or agri 
meaning soil and 
culture meaning, 
cultivation.

t ypeS OF Farming Farming is practised in various ways across the world. 
Depending upon the geographical conditions, demand 
of produce, labour and level of technology, farming can 
be classified into two main types. These are subsistence 
farming and commercial farming.
Subsistence Farming
This type of farming is practised to meet the needs of the 
farmer’s family. Traditionally, low levels of technology 
and household labour are used to produce on small 
output. Subsistence farming can be further classified 
as intensive subsistence and primitive subsistence 
farming.
In intensive subsistence agriculture the farmer 
cultivates a small plot of land using simple tools and 
more labour. Climate with large number of days with 
sunshine and fertile soils permit growing of more than 
one crop annually on the same plot. Rice is the main 
crop. Other crops include wheat, maize, pulses and 
oilseeds. Intensive subsistence agriculture is prevalent 
in the thickly populated areas of the monsoon regions 
of south, southeast and east Asia.

Shifting cultivation 
is known by 
different names in 
different parts of 
the world
Jhumming - 
North-East India 
Milpa -Mexico 
Roca - Brazil.
Ladang - Malaysia
Primitive subsistence agriculture includes shifting 
cultivation and nomadic herding.
Shifting cultivation is practised in the thickly 
forested areas of Amazon basin, tropical Africa, parts of 
southeast Asia and Northeast India. These are the areas 
of heavy rainfall and quick regeneration of vegetation. 
A plot of land is cleared by felling the trees and burning 
them. The ashes are then mixed with the soil and crops 
like maize, yam, potatoes and cassava are grown. After 
the soil loses its fertility, the land is abandoned and the 
cultivator moves to a new plot. Shifting cultivation is 
also known as ‘slash and burn’ agriculture.
Nomadic herding is practised in the semi-arid 
and arid regions of Sahara, Central Asia and some 
parts of India, like Rajasthan and Jammu and 
Kashmir. In this type of farming, herdsmen 
move from place to place with their animals for 
fodder and water, along defined routes. This 
type of movement arises in response to climatic 
constraints and terrain. Sheep, camel, yak and 
goats are most commonly reared. They provide 
milk, meat, wool, hides and other products to 
the herders and their families.
Commercial Farming
In commercial farming  crops are grown and  
animals are reared for sale in market. The area 
cultivated and the amount of capital used is 
large. Most of the work is done by machines. 
Commercial farming includes commercial 
grain farming, mixed farming and plantation 
agriculture (Fig 4.5).
In commercial grain farming crops are grown 
for commercial purpose. Wheat and maize are 
common commercially grown grains. Major 
areas where commercial grain farming is 
pracised are temperate grasslands of North America, 
Europe and Asia. These areas are sparsely populated 
with large farms spreading over hundreds of hectares. 
Severe winters restrict the growing season and only a 
single crop can be grown.
In mixed farming the land is used for growing 
food and fodder crops and rearing livestock.

42 r esources And d evelopment It is practised in Europe, eastern USA, Argentina, 
southeast Australia, New Zealand and South Africa.
Plantations are a type of commercial farming 
where single crop of tea, coffee, sugarcane, cashew, 
rubber, banana or cotton are grown. Large amount 
of labour and capital are required. The produce may 
be processed on the farm itself or in nearby factories. 
The development of a transport network is thus 
essential for such farming.
Major plantations are found in the tropical 
regions of the world. Rubber in Malaysia, coffee 
in Brazil, tea in India and Sri Lanka are some 
examples.
Major Crops
A large variety of crops are grown to meet the 
requirement of the growing population. Crops also 
supply raw materials for agro based industries. 
Major food crops are wheat, rice, maize and 
millets. Jute and cotton are fibre crops. Important 
beverage crops are tea and coffee.
Rice: Rice is the major food crop of the world. It 
is the staple diet of the tropical and sub-tropical 
regions. Rice needs high temperature, high 
humidity and rainfall. It grows best in alluvial 
clayey soil, which can retain water. China leads in 
the production of rice followed by India, Japan, Sri 
Lanka and Egypt. In favourable climatic conditions 
as in West Bengal and Bangladesh two to three 
crops are grown in a year.
Wheat: Wheat requires moderate temperature and 
rainfall during growing season and bright sunshine 
at the time of harvest. It thrives best in well drained 
loamy soil. Wheat is grown extensively in USA, 
Canada, Argentina, Russia, Ukraine, Australia 
and India. In India it is grown in winter.
Millets: They are also known as coarse grains and 
can be grown on less fertile and sandy soils. It is 
a hardy crop that needs low rainfall and high to
