Agricultural productivity is measured as the ratio of agricultural outputs to inputs. [1] While individual products are usually measured by weight, which is known as crop yield, varying products make measuring overall agricultural output difficult. Therefore, agricultural productivity is usually measured as the market value of the final output ...
Along with climate and corresponding types of vegetation, the economy of a nation also influences the level of agricultural production. Production of some products is highly concentrated in a few countries, China, the leading producer of wheat and ramie in 2013, produces 95% of the world's ramie fiber but only 17% of the world's wheat.
The following list, derived from the statistics of the United Nations' Food and Agriculture Organization (FAO), lists the most valuable agricultural products produced by the countries of the world. [1] The data in this article, unless otherwise noted, was reported for 2016.
For example, in addition to providing food and plant-derived products for the population, agriculture may also provide jobs for rural people and contribute to the viability of the area, create a more stable food supply, and provide other desired environmental and rural outputs. [3]
Intensive agriculture, also known as intensive farming (as opposed to extensive farming), conventional, or industrial agriculture, is a type of agriculture, both of crop plants and of animals, with higher levels of input and output per unit of agricultural land area.
Continuous grazing by sheep or cattle is a widespread extensive farming system, with low inputs and outputs.. Extensive farming most commonly means raising sheep and cattle in areas with low agricultural productivity, but includes large-scale growing of wheat, barley, cooking oils and other grain crops in areas like the Murray-Darling Basin in Australia.
According to the National Cotton Council of America, in 2014, China was the world's largest cotton-producing country with an estimated output of about one hundred million 480-pound bales. [ 1 ] A cash crop , also called profit crop , is an agricultural crop which is grown to sell for profit.
For example, given its reliance on natural processes, the agriculture sector is disproportionately exposed and vulnerable to adverse climate-related events, especially droughts, floods and storms. [ 1 ] [ 2 ] Over half of all shocks to crop production are the result of extreme weather events, reinforcing concern about the vulnerability of ...
