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. Products ...
Given the long-term importance of agriculture, to date, only 0.08% of known land plant species and 0.0002% of known land animal species have been domesticated, compared with 0.17% of known marine plant species and 0.13% of known marine animal species. Domestication typically involves about a decade of scientific research. [15]
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.
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 ...
By 2015, the agricultural output of China was the largest in the world, followed by the European Union, India and the United States. [106] Economists measure the total factor productivity of agriculture, according to which agriculture in the United States is roughly 1.7 times more productive than it was in 1948.
For example, in 2018, agriculture, forestry, and fishing comprised more than 15% of GDP in sub-Saharan Africa [4] but less than 1% of GDP in North America. [ 5 ] In developed countries the primary sector has become more technologically advanced, enabling for example the mechanization of farming, as compared with lower-tech methods [ a ] in ...
The world's agrifood systems comprise a gargantuan global enterprise that each year produces approximately 11 billion tonnes of food [3] and a multitude of non-food products, including 32 million tonnes of natural fibres [4] and 4 billion m 3 of wood. The estimated gross value of agricultural output in 2018 was US$3.5 trillion. [5]
A well-known example of already ongoing agricultural expansion is the proliferation of palm oil production areas or the land conversion/deforestation for soy bean production in South America. Today's land grabbing activities are often a consequence of the strive for agricultural land by growing economies. [6]
