What is meaning intensive agriculture?

intensive agriculture, in agricultural economics, system of cultivation using large amounts of labour and capital relative to land area.

Is agriculture energy intensive?

Agricultural inputs tend to have lower energy demands than marine- or livestock-derived inputs; hence, lower trophic-level feeds may reduce energy intensity (83). However, there is a wide range in energy intensity both within and between feed input categories.

What is energy agriculture?

Agriculture requires energy as an important input to production. Agriculture uses energy directly as fuel or electricity to operate machinery and equipment, to heat or cool buildings, and for lighting on the farm, and indirectly in the fertilizers and chemicals produced off the farm.

What is intensive subsistence agriculture?

  • Crops.
  • Aquaculture.
  • Sustainability.
  • Environmental Disadvantages.
  • Poor Living Conditions And Hygiene For Livestock.
  • Excessive Use Of Agro-Chemicals.
  • Deforestation.

What type of agriculture is the most energy intensive?

Mineral fertilizers, chemical pesticides, fungicides and herbicides all require energy in their production, distribution and transport processes. Fertilizers form the largest of these energy inputs to agriculture, whilst pesticides are the most energy-intensive agricultural input (on a per kg basis of chemical).

How much energy does agriculture use?

In 2016, the agricultural sector consumed 1,872 trillion Btu of energy, accounting for about 1.9 percent of total U.S. primary energy consumption.

What are the sources of energy in agriculture?

The direct energy inputs to agriculture are in the form of gasoline, diesel fuel, electricity, and space heating fuels, including natural gas where available and are used in the production of crops and animals. Direct fuel use in farm production can be as high as 50 percent of total farm energy use.

Why does agriculture need energy?

2.4 Agricultural Energy Needs The direct energy needs include energy required for land preparation, cultivation, irrigation, harvesting, post-harvest processing, food production, storage and the transport of agricultural inputs and outputs.

What is extensive and intensive agriculture?

Intensive farming focuses on investing a lot of resources and labor into small tracts of land in order to increase yield. Extensive agriculture, on the other hand, employs larger tracts of land and lower quantities of labor and resources.

Where is intensive subsistence agriculture?

Intensive subsistence farming is best developed in the monsoon lands of Asia. This type of agriculture can be found in China, Japan, Korea, India, Pakistan, Sri Lanka, in a big part of continental South-East Asia, and some parts of insular South-East Asia as well.
