Chapter 3 Agriculture



Observing a farmer tilling land and preparing it for growing wheat demonstrates a fundamental human activity related to producing food. The process of transforming a plant (wheat) into finished products like bread and biscuits involves a series of economic activities.


Economic activities can be broadly categorised into three types:

1. **Primary Activities:** These involve the direct **extraction and production of natural resources**. Examples include **agriculture**, fishing, and gathering.

2. **Secondary Activities:** These are concerned with the **processing of natural resources** obtained from primary activities. Examples include manufacturing goods, such as the production of steel, baking bread from flour, or weaving cloth.

3. **Tertiary Activities:** These activities provide **support and services** to the primary and secondary sectors. They do not produce goods directly but facilitate their production, distribution, and sale. Examples include transport, trade, banking, insurance, and advertising.


**Agriculture** is classified as a **primary activity**. It encompasses various practices including growing crops, fruits, vegetables, and flowers, as well as rearing livestock (animals). Globally, a significant portion of the population is engaged in agricultural activities. For instance, in India, approximately two-thirds of the population still relies on agriculture for their livelihood.


Successful agricultural activity is heavily dependent on favourable environmental conditions, particularly the **topography of the soil** and the prevailing **climate**. The land specifically used for growing crops is known as **arable land**.


As indicated in the map showing the world distribution of arable land (Fig. 3.1), agricultural activity is concentrated in regions with suitable factors for crop cultivation. This highlights the importance of geographical and climatic conditions for farming.

World map showing the distribution of arable land.

Fig. 3.1 is a map illustrating where arable land is found globally. It shows that fertile, farmable land is not evenly distributed but concentrated in specific regions, often corresponding to areas with suitable climates and fertile soils, explaining the concentration of agricultural activity in those areas.


The term 'agriculture' originates from Latin words: 'ager' or 'agri', meaning **soil**, and 'culture', meaning **cultivation**. Hence, agriculture fundamentally refers to the cultivation of soil.


Related terms include:


**Agriculture**, also known as farming, is defined as the science and art of cultivating the soil, raising crops, and rearing livestock.


Farm System

Agriculture or farming can be viewed as a complex **system**. Like any system, it involves inputs, processes, and outputs.


The key components of a farm system are:

1. **Inputs:** These are the resources and materials that go into the farming process. Important inputs include **seeds, fertilisers, machinery, and labour**. Inputs can be broadly categorised into Physical Inputs (like sunshine, temperature, soil, rainfall, slope) and Human Inputs (like storage facilities, labour, machinery, chemicals).

2. **Processes:** These are the actual operations and activities carried out on the farm. Examples of processes include **ploughing, sowing, irrigation, weeding, and harvesting**.

3. **Outputs:** These are the products or results obtained from the farming system. Outputs from a farm can include **crops** (like grains, fruits, vegetables), **wool** (from sheep), **dairy products** (milk, cheese, butter), and **poultry products** (eggs, chicken).

Fig. 3.3 further details the inputs in a farm system, differentiating between Physical Inputs (climatic and geographical factors like sunshine, temperature, soil type, slope, rainfall) and Human Inputs (resources and tools provided by humans like machinery, seeds, chemicals, labour, and storage facilities), showing how both are essential for farming.



Types Of Farming

Farming practices vary significantly across the world, influenced by local geographical conditions, the demand for produce, the availability of labour, and the level of technology used. Based on these factors, farming is broadly classified into two main types:

1. **Subsistence Farming**

2. **Commercial Farming**


Subsistence Farming

**Subsistence farming** is agricultural practice primarily aimed at meeting the food and other essential needs of the **farmer's family**. The produce is mainly for self-consumption rather than sale in the market.


Key characteristics of traditional subsistence farming:


Subsistence farming can be further divided into:

a) **Intensive Subsistence Agriculture:**

b) **Primitive Subsistence Agriculture:** This category includes two distinct practices:

Fig. 3.4 shows Nomadic Herders with their camels. This image illustrates the practice of Nomadic Herding, a type of primitive subsistence agriculture where communities move with their livestock across vast areas in search of pasture and water, adapting to challenging environmental conditions.


Commercial Farming

**Commercial farming** is agricultural practice where crops are grown and animals are reared specifically for **sale in the market**. The primary goal is profit rather than just meeting family needs.


Key characteristics of commercial farming:


Commercial farming includes several types:

Photo of a Sugarcane plantation.

Fig. 3.5 shows a Sugarcane plantation. Plantations are large-scale commercial farms dedicated to growing a single crop, requiring significant investment and labour, characteristic of commercial agriculture in tropical regions.

Photo of a Banana Plantation.

Fig. 3.6 shows a Banana Plantation. Like sugarcane plantations, banana plantations exemplify single-crop commercial farming requiring specific tropical climates and efficient transport links to markets.


**Organic Farming** is an interesting method that uses organic manure and natural pesticides instead of chemical inputs. Genetic modification is also avoided. This approach focuses on sustainable and environmentally friendly practices.



Major Crops

A wide variety of crops are cultivated globally to meet the increasing demands of the growing population and to provide raw materials for agro-based industries. The major crops can be categorised into food crops, fibre crops, and beverage crops.


**Major Food Crops:**


**Major Fibre Crops:**


**Important Beverage Crops:**

Photo showing Rice Cultivation.

Fig. 3.7 shows Rice Cultivation. This image likely depicts flooded fields, characteristic of wet rice cultivation, the method used for growing rice, a staple food crop requiring specific conditions of high temperature, humidity, and water availability.

Photo showing Wheat Harvesting.

Fig. 3.8 shows Wheat Harvesting. This image illustrates the process of gathering the mature wheat crop, which thrives in moderate temperatures and requires sunshine during this final stage.

Photo showing Bajra Cultivation (a type of millet).

Fig. 3.9 shows Bajra Cultivation. Bajra, a type of millet, is a hardy grain that can grow in less fertile, sandy soils and requires low to moderate rainfall, making it suitable for drier regions.

Photo showing Maize Cultivation.

Fig. 3.10 shows Maize Cultivation. Maize (corn) is grown in diverse climates and requires moderate temperature, rainfall, and plenty of sunshine for good growth.

Photo showing Cotton Cultivation.

Fig. 3.11 shows Cotton Cultivation. Cotton, a key fibre crop, needs specific warm climatic conditions, including many frost-free days and ample sunshine, and grows well in black or alluvial soils.

Photo showing a Coffee Plantation.

Fig. 3.12 shows a Coffee Plantation. Coffee, a major beverage crop, is typically grown on well-drained loamy soils, often on hill slopes, requiring a warm and wet climate.

Photo showing a Tea Plantation.

Fig. 3.13 shows a Tea Plantation. Tea, another important beverage crop, thrives in cool climates with high, evenly distributed rainfall and requires gentle slopes and well-drained loamy soil. The image likely shows the characteristic rows of tea bushes cultivated on hillsides.



Agricultural Development

**Agricultural Development** refers to the systematic efforts undertaken to **increase farm production**. The primary motivation for this development is to meet the ever-growing demand for food and agricultural products from an increasing global population. Achieving agricultural development involves various strategies:


The ultimate goal of agricultural development is to enhance **food security**, which means ensuring that all people, at all times, have access to sufficient, safe, and nutritious food to meet their dietary needs for a healthy and active life.


Agricultural development has occurred at different rates and in different ways across the world. In **developing countries** with large populations, **intensive agriculture** is often practised on small landholdings, primarily for **subsistence** (feeding the family). In contrast, **developed countries** like the USA, Canada, and Australia often have much **larger landholdings** that are better suited for **commercial agriculture**, focusing on large-scale production for the market.


Comparing farms in India (a developing country) and the USA (a developed country) illustrates these differences:


A Farm in India (Case study of Munna Lal in Adilabad village, Ghazipur, UP):
