Permanent crops are sown or planted once, and then occupy the land for some years and need not be replanted after each annual harvest, such as cocoa, coffee and rubber. Ellis, E. C., Klein Goldewijk, K., Siebert, S., Lightman, D., & Ramankutty, N. (2010). Anthropogenic transformation of the biomes, 1700 to 2000. Note that species can have multiple threats; this therefore does not mean agriculture was the only threat for such species. Rome, FAO. This data can be viewed for other countries and regions by selecting ‘ The abandoned land resulting from shifting cultivation is not included in this category. In the map here we see the share of permanent meadows and pasture as a percentage of total land area. Available online. Advertisement. Global Ecology and Biogeography, 19(5), 589-606. We discuss these determinants, and where Ausubel’s predictions diverge from actual trends here. Area of land covered by forests. Whilst premature, the authors’ model for estimating arable land requirements provides a useful explanation of the variables which will determine at what date we reach this peak. The global average per capita protein availability from vegetal products was 49 grams per person per day, and 32g from animal products. global land allocated to livestock – either in the form of grazing land or cropland used for animal feed is equivalent to the area of the Americas (North, Central and South America combined); cropland (minus land used for the production of animal feed) is equivalent to the area of East Asia-Pacific, extending as far south as Thailand; forested area is equal to Africa (minus Libya), the Middle East and South Asia; global freshwater (inland water bodies) approximates to the area of Mongolia. Despite this uncertainty, most analyses tend to converge on an estimate of close to half of habitable land being used for agriculture. The FAO explains the construction of the PIN in detail here. Today, the world population uses approximately 50 percent of total habitable land for agriculture. These numbers are taken from FAO (2013) – Statistical Yearbook. According to the same World Bank report, Greenland’s percentage of land that is used for agriculture accounted for 0.6% of its total land area as of 2013. If we rewind 1000 years, it is estimated that only 4 million square kilometers – less than 4% of the world’s ice-free and non-barren land area was used for farming.In the visualization we see the breakdown of global land area today. This leaves only 37% for forests; 11% as shrubs and grasslands; 1% as freshwater coverage; and the remaining 1% – a much smaller share than many suspect – is built-up urban area which includes cities, towns, villages, roads and other human infrastructure. We will explore this difference in cropland and pastureland in the following section. In 2019, 28,338 were listed as threatened with extinction. Jesse H. Ausubel, Iddo K. Wernick, Paul E. Waggoner (2013) – Peak Farmland and the Prospect for Land Sparing. In 2019, 24,001 species were threatened by ‘agriculture and aquaculture’. Population and Development Review, Volume 38, Issue Supplement s1, pages 221–242, February 2013. It should be noted that the authors derived their rate of decline (at 0.2 percent per year) based on an average prediction over the period 2010-2060; therefore a divergence from this value over the first 5-year period does not necessarily confirm these averaged predictions to be false. This entry can be cited as: Our World in Data is free and accessible for everyone. Animal products therefore accounted for [32 / (32 + 49) * 100] = 39% of the world’s protein. You can use all of what you find here for your own research or writing. Online here. The noticeable shrinkage in the extent of cropland as a function of the Crop Production index since 1990 provides encouragement that farmers will continue sparing land.’. This is the definition given by the UN’s Food and Agricultural Organization (FAO) in their glossary that is online here. Help us do this work by making a donation. What determines the amount of arable land we use? The maximum idle period is usually less than five years.’. Despite this uncertainty, most analyses tend to converge on an estimate of close to half of habitable land being used for agriculture. The focus of this entry is land use for agriculture. There are two main uses of agricultural land: arable farming (which is land dedicated to growing crops), and pastureland (which includes meadows and pastures used for livestock rearing).
