Agricultural expansion describes the growth of agricultural land (arable land, pastures, etc.) especially in the 20th and 21st centuries.. The agricultural expansion is often explained as a direct consequence of the global increase in food and energy requirements due to continuing population growth (both which in turn have been attributed to agricultural expansion itself [1] [2]), with an ...
Percentage figures for arable land, permanent crops land and other lands are all taken from the CIA World Factbook [1] as well as total land area figures [2] (Note: the total area of a country is defined as the sum of total land area and total water area together.) All other figures, including total cultivated land area, are calculated on the ...
(c) The projected agricultural land gap, assuming a business-as-usual scenario and measured in land area required to support all agricultural food production, is 0.4 billion ha of pastureland and 0.2 billion ha of cropland, a total 12% increase. Note the non-zero baseline in this panel.
More than half of Gaza's agricultural land, crucial for feeding the war-ravaged territory's hungry population, has been degraded by conflict, satellite images analysed by the United Nations show.
Even today, 35% of anthropogenic carbon dioxide contributions can be attributed to land use or land cover changes. [20] Currently, almost 50% of Earth’s non-ice land surface has been transformed by human activities, with approximately 40% of that land used for agriculture, surpassing natural systems as the principal source of nitrogen emissions.
One-third of the total agricultural land was cropland (1.58 billion ha in 2021), which increased by 6 percent (0.09 billion ha). [ 10 ] [ 11 ] Asia had the largest share of the global cropland area in 2021 (37 percent), followedby the Americas (24 percent), Africa (19 percent), Europe (18 percent) and Oceania (2 percent).
For example, Europe on average imports over 50% of its food. Meanwhile, 44% of agricultural land is located in dry lands and it supplies 60% of the world's food production. Desertification is decreasing the amount of sustainable land for agricultural uses but demands are continuously growing.
Arable density (m² per capita) by country. This is a list of countries ordered by physiological density."Arable land" is defined by the UN's Food and Agriculture Organization, the source of "Arable land (hectares per person)" as land under temporary crops (double-cropped areas are counted once), temporary meadows for mowing or for pasture, land under market or kitchen gardens, and land ...
