Class 8 Geography Chapter 4 Notes - Agriculture

Introduction

The economic transformation from plant to product involves primary, secondary, and tertiary activities.

  • Primary Activities: Involves extraction and production of natural resources.
    Examples: Agriculture, fishing, and gathering.
  • Secondary Activities: Concerned with the processing of extracted resources.
    Examples: Manufacturing of steel, baking of bread, and weaving of cloth.
  • Tertiary Activities: Provide support to the primary and secondary sectors through services.
    Examples: Transport, trade, banking, insurance, and advertising.

Farm System

  • Key Inputs in Agriculture: Essential inputs include seeds, fertilizers, machinery, and labor.
  • Operations in Agriculture: Required operations consist of ploughing, sowing, irrigation, weeding, and harvesting.
  • Outputs from the Agricultural System: The system yields crops, wool, dairy, and poultry products.

Types of Farming

Class 8 Geography Chapter 4 Notes - Agriculture

Farming can be classified into two main types based on geographical conditions, demand of produce, labor, and level of technology.

  • Subsistence farming
  • Commercial farming

1. Subsistence Farming

  • Practiced to meet the needs of the farmer’s family.
  • Utilizes low levels of technology and household labor for small output.

Classification of Subsistence Farming

Subsistence farming can be further classified into:

  • Intensive subsistence farming
  • Primitive subsistence farming

Intensive Subsistence Farming

  • Involves cultivating a small plot of land using simple tools and more labor.
  • Suitable climate allows for the annual growth of multiple crops on the same plot.
  • Main crop: Rice; others include wheat, maize, pulses, and oilseeds.
  • Prevalent in densely populated areas of monsoon regions in south, southeast, and east Asia.

Primitive Subsistence Farming

Shifting Cultivation

  • Practiced in heavily forested areas of the Amazon basin, tropical Africa, parts of southeast Asia, and Northeast India.
  • Method involves clearing land by felling and burning trees, mixing ashes with soil for crop growth.
  • Also known as 'slash and burn' agriculture.

Nomadic Herding

  • Practiced in semi-arid and arid regions of Sahara, Central Asia, and some parts of India (e.g., Rajasthan, Jammu and Kashmir).
  • Herdsmen move with animals for fodder and water along defined routes.
  • Commonly reared animals: sheep, camel, yak, and goats, providing milk, meat, wool, hides, and other products for herders and their families.

2. Commercial Farming

  • Involves growing crops and rearing animals for sale in the market.
  • Requires large cultivated areas and substantial capital investment.
  • Relies heavily on machinery for most tasks.

Types of Commercial Farming

Commercial Grain Farming

  • Involves growing crops for commercial purposes.
  • Common crops: Wheat and maize.
  • Predominant in temperate grasslands of North America, Europe, and Asia.
  • Severe winters restrict the growing season to a single crop.

Mixed Farming

  • Land is used for growing food and fodder crops, along with rearing livestock.
  • Practiced in areas such as Europe, eastern USA, Argentina, southeast Australia, New Zealand, and South Africa.

Plantation Agriculture

  • Focuses on cultivating a single crop like tea, coffee, sugarcane, cashew, rubber, banana, or cotton.
  • Requires significant labor and capital investment.
  • Processing may occur on the farm or in nearby factories, necessitating transportation facilities.
  • Common in tropical regions worldwide, with examples like rubber in Malaysia, coffee in Brazil, and tea in India and Sri Lanka.

Major Crops

Class 8 Geography Chapter 4 Notes - Agriculture

Rice

  • Major global food crop, staple diet in tropical and sub-tropical regions.
  • Requires high temperature, humidity, and rainfall.
  • Thrives in alluvial clayey soil that retains water.
  • Leading producers: China, India, Japan, Sri Lanka, and Egypt.

Wheat

  • Requires moderate temperature and rainfall during the growing season, with bright sunshine at harvest.
  • Thrives in well-drained loamy soil.
  • Grown extensively in USA, Canada, Argentina, Russia, Ukraine, Australia, and winter season in India.

Millets

  • Also known as coarse grains, grown on less fertile and sandy soils.
  • Hardy crop with low rainfall and high to moderate temperature requirements.
  • Grown in India (e.g., Jowar, bajra, and ragi) and other countries like Nigeria, China, and Niger.

Maize

  • Requires moderate temperature, rainfall, and abundant sunshine.
  • Thrives in well-drained fertile soils.
  • Grown in North America, Brazil, China, Russia, Canada, India, and Mexico.

Cotton

  • Requires high temperature, light rainfall, 210 frost-free days, and bright sunshine.
  • Best suited for black and alluvial soils.
  • Major producers: China, USA, India, Pakistan, Brazil, and Egypt.
  • Key raw material for the cotton textile industry.

Jute

  • Also known as 'Golden Fibre.'
  • Grows well on alluvial soil with high temperature, heavy rainfall, and a humid climate.
  • Primarily grown in tropical areas, with India and Bangladesh as leading producers.

Coffee

  • Requires a warm and wet climate, along with well-drained loamy soil.
  • Hill slopes are more suitable for growth.
  • Leading producers: Brazil, Colombia, and India.

Tea

  • Beverage crop grown on plantations.
  • Requires well-drained loamy soils, gentle slopes, cool climate, and consistent high rainfall.
  • Labor-intensive for leaf picking.
  • Leading producers: Kenya, India, China, and Sri Lanka, known for producing high-quality tea.

Agricultural Development

It involves efforts to boost farm production to meet the rising demand of a growing population.

Strategies for Agricultural Development:

  • Increasing the cropped area
  • Increasing the number of crops grown
  • Improving irrigation facilities
  • Use of fertilizers and high-yielding varieties of seeds

Ultimate Goal of Agricultural Development:

  • Aims to enhance food security.

A Farm in India

Class 8 Geography Chapter 4 Notes - Agriculture

  • Small Size Farmland: Cultivating a small-sized piece of land.
  • Utilization of HYV Seeds: Employing high-yielding variety (HYV) seeds purchased from markets.
  • Seeking Guidance: Seeking advice from friends, elders, or government sources.
  • Ploughing Methods: Using tractors or bullock carts for field ploughing.
  • Irrigation Practices: Utilizing tubewells for irrigation activities.
  • Livestock Rearing: Engaging in livestock rearing to supplement income.
  • Family Involvement: Involving all family members in various farm activities.
  • Financial Support: Taking credit from a bank or agricultural cooperative society to purchase HYV seeds and implements.
  • Market Constraints: Facing challenges due to a lack of storage facilities, leading to selling produce even in unfavorable market conditions.
  • Government Initiatives: Recently, the government has taken steps to develop storage facilities.
