The BBC is not responsible for the content of external sites. One global hectare is the world's annual amount of biological production for human use and human waste assimilation, per hectare of biologically productive land and fisheries. This measure allows different countries and areas of the planet to be compared with each other, even if they differ greatly from their natural conditions and ressources, e.g. . Please consult our full legal disclaimer. The visualisation shows human land use over the long-term (since 10,000 BC), and details the change in total land used for cropland, grazing land and built-up/urban area in hectares. The combined land appropriation for producing agricultural, livestock, fishery and aquaculture, and timber products as well as the greenhouse gas emissions and built-up surfaces including roads, factories, and cities linked to that production. That's because it takes account of carbon emissions. Despite this uncertainty, most analyses tend to converge on an estimate of close to half of habitable land being used for agriculture. It is therefore useful to understand the differences between land use terminology; for example, the definition of arable land versus agricultural land. times the "world-wide production per hectare"). Rates of reduction in South Asia have been the most dramatic; per capita land use in 2014 was roughly one-third of its value in 1961.

A hectare (/hktr/; symbol ha) is a unit of area equal to 10,000 square metres (107,639sqft) (a square 100 metres on each side or 328 feet on each side), 2.471 acres, 0.01 square kilometers, 0.00386102 square miles, or one square hectometre (100 metres squared). Allocation ranges from less than ten percent, particularly across countries in Sub-Saharan Africa and the Scandinavian region to close to 80 percent across most regions (including the UK, Uruguay, South Africa, Nigeria and Saudi Arabia). The abandoned land resulting from shifting cultivation is not included in this category. Examples of biologically productive areas include cropland, forests, and fishing grounds; they do not include deserts, glaciers, and the open ocean. This visualization shows the index of the arable land area needed to produce an equivalent aggregate of crop production, relative to the land area needed in 1961 i.e. hectare | translate French to English - Cambridge Dictionary Ez da ohiko hektarea (10.000 m2) batekin nahastu behar. While these figures may not be perfect, Wackernagel says that governments can find them useful as a way of thinking about policies on the environment. Opponents and defenders of the concept have discussed its strengths and weaknesses.[6]. A unit of measured productivity used to report both the. Livestock farming can take place across a range of diverse climatic and environmental regions (for example, ranging from cattle rearing in temperate regions to sheep farming in hilly and semi-arid terrain); meaning that this type of agriculture is potentially less geographically-constrained than arable farming. hectare noun [ masculine ] / kta/ Add to word list (unit de mesure des surfaces) unit qui sert mesurer les surfaces hectare un terrain de cent hectares a one hundred hectare plot J'ignore combien d'hectares nous cultivons. Thus consumption per person can be labeled as half, 1, 2, etc. The article cites "Living Planet Report 2004" but the link diverts to Living Planet Report 2016. Our World In Data is a project of the Global Change Data Lab, a registered charity in England and Wales (Charity Number 1186433). Values per areas (different agroecological zones) are scaled proportionally to their biological productivity resulting in a comparable unit of analysis - the global hectare. Environmental security and regional stability in the Persian Gulf It is primarily used to measure land area. Global Issues - Examples Global climate change Energy crisis Population explosion Pollution Loss of biodiversity Prendendo il totale della della Terra e dividendolo per il numero degli ettari della sua superficie si ottiene la media di produttivit per ettaro.

In the map here we see the share of permanent meadows and pasture as a percentage of total land area. View Map View Graph . Global hectares per person equals production+waste assimilation per person. You have the permission to use, distribute, and reproduce these in any medium, provided the source and authors are credited. . The most dramatic increase in land allocation is in the production of oilcrops. The article does not say what biological production is measured: Total biomass? This is possible because there are natural reserves all around the globe that function as backup food, material and energy supplies, although only for a relatively short period of time. The UK, meanwhile, has formed a Natural Capital Committee to study how the country consumes its natural resources and how long, at current rates, they will last.

But where does this claim originate, and how is it calculated? The term "global hectar" was introduced in the early 2000s,[4] based on a similar concept from the 1970s named "ghost acreage". In the chart here we have plotted the average land required (sometimes termed the land footprint) to produce one gram of protein across a range of food types. Yes, humans are depleting Earth's resources, but 'footprint' estimates '7, The same source defines permanent crops as follows: Permanent crops are divided into temporary and permanent crops. Total ecological footprint of production per person. Total land area used for oilcrop production has increased almost 3-fold since 1961 an area just short of the size of Mexico. Language links are at the top of the page across from the title. There are 100 hectares in one square kilometre. The article needs to present both a simple definition and a full definition.

GHA - Global Hectare (biocapacity measurement) | AcronymFinder The total of these kinds of production, weighted by the richness of the land they use,[1] is divided by the number of hectares used. Agriculture is a major use of land. It has transformed habitats and is one of the greatest pressures for biodiversity: of the 28,000 species evaluated to be threatened with extinction on the IUCN Red List, agriculture is listed as a threat for 24,000 of them.4 But we also know that we can reduce these impacts both through dietary changes, by substituting some meat with plant-based alternatives and through technology advances. These numbers are taken from FAO (2013) Statistical Yearbook. Both biocapacity and Ecological Footprint are expressed in a common unit called a global hectare (gha). Duurzaamheid houdt in dat er niet meer wordt gebruikt dan er wordt geproduceerd. FAQ - Global Footprint Network Convert hectare to acres - Unit Converter However, land use across Europe and Central Asia- particularly within the European Union (EU) zone- and North America has been declining.

Talk:Global hectare - Wikipedia Kuwait comes top with 8.9 global hectares (5.1 Earths), followed by Australia (4.8 Earths), the United Arab Emirates (4.7 Earths) and Qatar (4.0 Earths). One global hectare measures the average productivity of all biologically productive areas (measured in hectares) on earth in a given year. We would need the regenerative capacity of 1.6 Earths to provide the natural resources and ecological services we currently use. Germany, for instance, has 1.6 . Population and Development Review, Volume 38, Issue Supplement s1, pages 221242, February 2013. Here, land use groupings are aggregated to show the total surface area allocated for each. The ecological footprint is measured in global hectares. The Americas (North and South) and Africa have notably higher per capita agricultural land use relative to Europe and Asia. In 2012 there were approximately 12.2 billion global hectares of production and waste assimilation, averaging 1.7 global hectares per person.Consumption totaled 20.1 billion global hectares or 2.8 global hectares per person, meaning about 65% more was consumed than produced. An exploration of the mathematics behind the Ecological Footprint. which is at. The global hectare is a useful measure of biocapacity as it can convert things like human dietary requirements into common units, which can show how many people a certain region on earth can sustain, assuming current technologies and agricultural methods. These productivity weighted biologically productive hectares allow researchers to report both the biocapacity of the earth or a region, and the demand on biocapacity (the Ecological Footprint). Land Use - Our World in Data But how much of total land area is utilised for agriculture across the world? on the chart.The crop production index (PIN) is the sum of crop commodities produced (after deductions of quantities used as seed and feed). output per unit of input."

In the chart here we have plotted trends of the average arable land use per person across the worlds regions. It measures production and consumption of different products. Biology - Chapter 24 - Sustainability Flashcards | Quizlet The visualisation here shows the change in the average cropland use per person over the long-term (since 10,000 BC), measured in hectares per person. We use roughly half of global habitable land for agriculture. In 2013, the global average per capita energy availability from vegetal products was 2370 kilocalories per person per day, and 514kcal from animal products. values in 1961 are equal to 1.0. If we rewind 1000 years, it is estimated that only 4 million square kilometers less than 4% of the worlds ice-free and non-barren land area was used for farming.In the visualization we see the breakdown of global land area today.

Please refer to the appropriate style manual or other sources if you have any questions. "Global hectares per person" refers to the amount of production and waste assimilation per person on the planet. As an example, the ecological footprint for France is 4.7 global hectares per person, and global biocapacity is 1.7 hectares per person. One global hectare measures the average productivity of all biologically productive areas (measured in hectares) on earth in a given year. The following legacy units of area have been redefined as being equal to one hectare:[13], The metric system of measurement was first given a legal basis in 1795 by the French Revolutionary government. 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. Reducing the consumption of resource-intensive products and increasing the productivity of land makes it possible to produce food with much smaller inputs and reducing the impact on the environment. This category includes flowering shrubs, fruit trees, nut trees and vines, but excludes trees grown for wood or timber. Global population has more than doubled over the last 50 years. GLOBAL HECTARES definition - Linguazza.com To meet the demands of a rapidly growing population on a planet with finite land resources, reducing our per capita land footprint is essential. 1 / 20 Flashcards Learn Test Match Created by Clare_Alexander Teacher Terms in this set (20) Ecological Footprint IB DEFINITION: "The theoretical measurement of the amount of land and water a population requires to produce the resources it consumes and to absorb its waste under prevailing technology." Calculation takes into account which resources? This means that for the four Earths we would need if everyone consumed like an American, more than two-and-a-half of those would be needed just to absorb carbon dioxide. (Translation of hectare from the GLOBAL French-English Dictionary 2018 K Dictionaries Ltd) This is a list of countries by ecological footprint.The table is based on data spanning from 1961 to 2013 from the Global Footprint Network's National Footprint Accounts published in 2016. Poore, J., & Nemecek, T. (2018). FoDaFo was established in 2019 by York University and Global Footprint Network to be the stewards of those National Footprint and Biocapacity Accounts. The global hectare (gha) is a measurement of biocapacity of the entire earth - one global hectare is a measurement of the average biocapacity of all hectare measurements of any biologically productive areas on the planet. Due to rapid population growth, this figure is decreasing. The names centiare, deciare, decare and hectare are derived by adding the standard metric prefixes to the original base unit of area, the are. Africa in particular has seen dramatic reductions in agricultural land per person now less than one-third of per capita land 50 years ago. The maximum idle period is usually less than five years..

With solutions from both consumers and producers, we have an important opportunity to restore some of this farmland back to forests and natural habitats. 2020 WWF - World Wide Fund For Nature 1986 Panda Symbol WWF World Wide Fund For Nature (formerly World Wildlife Fund) WWF is a WWF Registered Trademark Creative Commons license. Mondiale hectares zijn verschillend qua grootte van plaats tot plaats. The FAO explains the construction of the PIN in detail here. For most countries, land dedicated to cropland is typically below 20 percent, with many countries dedicating less than 10 percent. 100m2 or 1100 hectare). Global hectare is a metaphor, since its units are production+assimilation per unit of area, not actually area. This page is not available in other languages. For more than 40 years, humanitys demand on nature has exceeded what our planet can replenish. A global hectare corresponds to a globally standardised, comparable hectare with average biological productivity. which is at, This page was last edited on 6 July 2022, at 15:44. Corrections? The others in the top 10 are Canada, Sweden, Bahrain, Trinidad and Tobago, and Singapore. Deforestation and Forest Loss - Our World in Data [22][23], The deciare (rarely used) is ten square metres.[24]. The total of these kinds of production, weighted by the richness of the land they use (Borucke 2013), is divided by the number of hectares used (Galli 2007). But Mathis Wackernagel says it is important to include carbon emissions in the calculation to capture the "total package" of our activity. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree. By definition, this equals 12.1 billion global hectares, as each global hectare represents the productive average of all these 12.1 billion hectares. Note that species can have multiple threats; this therefore does not mean agriculture was the only threat for such species. It starts with the total biological production and waste assimilation in the world, including crops, forests (both wood production and CO2 absorption), grazing and fishing.The total of these kinds of production, weighted by the richness of the land they use, is divided by the number of hectares used. However, its important to note the differences in land required across the meat products: poultry and pork have a land footprint 8-10 times lower than that of beef. We will always indicate the original source of the data in our documentation, so you should always check the license of any such third-party data before use and redistribution. Net increase in biomass after considering deaths? Global Hectare The measurement of biocapacity and ecological footprint. Compare the lifestyle of a subsistence farmer with that of a wealthy city-dweller in a developed country. The global average per capita protein availability from vegetal products was 49 grams per person per day, and 32g from animal products. Lur mota bakoitzak emankortasun bat duenez, lur emankor baten hektarea global batek (adibidez, zelai berde baten kasuan) emankorra ez den beste lur baten kasuan (adibidez, basamortua) baino azalera txikiagoa izango du, biek duen biogaitasuna bera izan arren. Although the are is the primary metric unit of land measurement, in practice the hectare is more commonly used. Visualising land use areas on a global map is perhaps the most relatable way to understand the scale of different land uses across the world. Ecological Indicators 24: 518-533. The 2004 report defines a global hectare as. All human activities that require a bioproductive area are summed. They can bring environmental benefits too: fertilizers can increase crop yields. The groupings and definitions shown below are based on the UN Food and Agricultural Organization (FAO) and should therefore be consistent with most international data sources. The key questions for GFN, he says, are: "If there is one planet - how much planet is available per person and how much planet do we use per person.".
