ECONOMIC GEOGRAPHY AGRICULTURE

Economic activities of humans are grouped under following four categories : 

  • Primary Activities: Hunting, food-gathering, fishing, live-stock raising, agriculture, mining, lumbering etc. 
  • Secondary Activities: Manufacturing industry. 
  • Tertiary Activities: Transport, communication, trade etc. 
  • Quaternary Activities: Higher range of services, education, management, research, etc. 

Agriculture 

Only 11 per cent of total landmass of the world coma under the agricultural activity in which 50 per cent of world's population is engaged. Following types of agriculture arc generally practiced in the world: 

  • Shifting Agriculture: The primitive form of agriculture is prevalent in the tribes of tropical forest, which is also called slash and burn agriculture and bush-fellow agriculture. 
    Shifting agriculture is called Bewar, Dahia, Peda in M.P. and Chhat-tisgarh, Podu in Andhra Pradesh, Kaman, Binga and Dhavi in Orissa, Kumari in Kerala, etc. 
  • Subsistence Agriculture: This type of agriculture is done for the con-sumption of farmers family involving mainly farming of food grains. Sub-sistence agriculture is practiced in the monsoonal climatic regions of Asia in which maximum utilisation of agricultural land is done. 
  • Commercial Agriculture: In this agriculture practiced 'mainly by the de-veloped countries, crops are grown for the commercial purpose. 
  • Intensive Agriculture: The main purpose of this agriculture, practiced in the regions of high population density, is to extract maximum production from the minimum agricultural land.
    i. Intensive subsistence agriculture is practiced in the developing coun-tries and intensive commercial agriculture is practiced in the devel-oped countries. 
  • Extensive Agriculture: This agriculture involves growing of crops by the modern scientific methods on large farms in which minimum labour and maximum use of machines are done.
    i. In this agriculture per hectare production is very low but per labour and total production is very high. 
    ii. The regions of temperate grasslands are noted for extensive agriculture. 
  • Plantation Agriculture (Estate farming): In this type of commercial agriculture huge amount of capital and labour is required. The development of this agriculture has taken place mainly in the coastal areas of tropical regions, where facility of marine navigation is available for the export of agricultural products. 
  • Mixed Agriculture: In the mixed agriculture both crops and livestocks are raised for the commercial purpose. This type of agriculture is practiced mainly in the densely populated areas of developed countries. 
  • Mixed Cropping: In this agriculture crops of different maturity period are grown simultaneously in a farm. 
  • Multiple Cropping: It refers to growing of two or more crops alternatively on a farm within the same year. 
  • Crop Rotation: In this, different crops are grown in a systematic succession in each field of a farm for the maintenance of soil nutrients for a long time. 
  • Dry Farming: Farming done without the facility of irrigation in the regions of inadequate rainfall is called dry farming. 
  • Truck Farming: The intensive, specialised production of fresh vegetables, fruits, and flowers at considerable distances from the metropolitan markets is called truck fanning in which the produce is sold. Truck farming is practiced on large scale in Florida and California of USA, Britain, France, Denmark, Italy, etc.

Major Crops

Wheat 

  • Wheat is mainly a crop of temperate region, but it is also grown in the sub-tropical regions. Wheat holds first position in the world in terms of agricultural area. 
    Necessary Conditions:
