Agriculture:

Agriculture is a primary activity where farmers grow crops that include vegetables, fruits and other plants. It serves as a primary resource for most people in rural areas. Being a primary resource, it concerns the growing, extraction and distribution of natural products. 

Factors influencing Agriculture:

Agriculture is dependent on various factors and resources. Soil, Water, Climate, and Population are some factors that influence agricultural activity. Also, depending upon various factors like soil, area and climate, different types of crops are grown in different regions. 

Types of Farming:

Farming is the activity where the soil is cultivated, and crops are grown as per the seasons and various patterns. Farming is broadly divided into two main categories:

  1. Subsistence farming
  2. Shifting cultivation

1. Subsistence farming:

This type of farming is done only to fulfil the family’s needs. Since the use is at the self-house level, the use of technology is minimal, creating a minimal output. 

Subsistence farming is further categorised into two types:

  1. Intensive subsistence farming
  2. Primitive Subsistence farming

For more details about types of farming, refer to Extramarks’ NCERT Solutions for Class 8 Geography Chapter 4. 

2. Shifting cultivation:

In this type of farming, by burning the vegetation present on the land, the farmer mixes the ashes into the soil and then cultivates the land. If the land becomes barren, the farmer moves to a new location. It is known as slash or burns.

Disadvantages of shifting cultivation:

  • Increases deforestation
  • Loss of fertility of the land
  • Soil erosion
  • Air pollution is due to the burning of trees and vegetation
  • For a large population, cultivation is insufficient

In different parts of the world, Shifting cultivation is known by different names as follows:

  • Jhumming – In northeast India
  • Milpa – In Mexico
  • Roca – In Brazil
  • Ladang – In Malaysia

To learn about farming types, students can read NCERT Solutions for Class 8 Geography Chapter 4, available on the Extramarks’ website. 

Plantation Agriculture:

A single crop is grown over the entire land in plantation agriculture. The crop may be tea, coffee, sugarcane, cashew, rubber, banana or cotton. Plantation agriculture is commercial farming where significant capital is required. The product obtained can be processed at the farm or any nearby factory. Hence to procure this farming, transportation is an important aspect. Some Examples of plantation agriculture are rubber in Malaysia, coffee in Brazil, and tea in India and Sri Lanka.

Fibre Crops:

The crops grown in the field for use as a fibre to make rope, clothes, etc., are termed as fibre crops. Jute and cotton are prominent examples of fibre crops. However, different climatic conditions are required to grow different types of fibre crops. 

Following are the climatic conditions required to grow cotton and jute.
