Agricultural census	Agricultural census or census of agriculture can be defined as a large-scale, periodic, statistical operation for the collection of quantitative information on the structure of agriculture. The word "census" implies a complete enumeration of all agricultural holdings. However, by extension it can be conducted by a sample enumeration, provided the sample is large enough to generate sub-national data.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Agricultural export quantity index	Quantity indices for the aggregate agricultural and aggregate food products represent the changes in the price-weighted sum of quantities of products traded between countries. The weights are the unit value averages of 1989-1991. The formulas used are of the Laspeyres type. Indices for food products include commodities that are considered edible and contain nutrients, except for animal feed products and alcoholic beverages. Coffee and tea are also excluded because, although edible, they have practically no nutritive value.	FAO Statistics Division
Agricultural export unit value index	Unit value indices for the aggregate agricultural and aggregate food products represent the changes in the quantity-weighted unit values of products traded between countries. The weights are the quantity averages of 1989-1991. The formulas used are of the Laspeyres type. Indices for food products include commodities that are considered edible and contain nutrients, except for animal feed products and alcoholic beverages. Coffee and tea are also excluded because, although edible, they have practically no nutritive value.	FAO Statistics Division
Agricultural export value index	Value indices represent the change in the current values of Export f.o.b (free on board) all expressed in US dollars.	FAO Statistics Division
Agricultural holding	Agricultural holding or holding is an economic unit of agricultural production under single management comprising all livestock kept and all land used wholly or partly for agricultural production purposes, without regard to title, legal form, or size. Single management may be exercised by an individual or household, jointly by two or more individuals or households, by a clan or tribe, or by a juridical person such as a corporation, cooperative or government agency. The holding's land may consist of one or more parcels, located in one or more separate areas or in one or more territorial or administrative divisions, providing the parcels share the same production means utilized by the holding, such as labour, farm buildings, machinery or draught animals. The requirement of sharing the same production means utilized by the holding, such as labour, farm buildings, machinery or draught animals should be fulfilled to a degree to justify the consideration of various parcels as components of one economic unit.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Agricultural import quantity index	Quantity indices for the aggregate agricultural and aggregate food products represent the changes in the price-weighted sum of quantities of products traded between countries. The weights are the unit value averages of 1989-1991. The formulas used are of the Laspeyres type. Indices for food products include commodities that are considered edible and contain nutrients, except for animal feed products and alcoholic beverages. Coffee and tea are also excluded because, although edible, they have practically no nutritive value.	FAO Statistics Division
Agricultural import unit value index	Unit value indices represent the changes in the quantity-weighted unit values of products traded between countries. The weights are the quantity averages of 1989-1991. The formulas used are of the Laspeyres type.	FAO Statistics Division

Data are expressed in numbers in use in the agricultural sector.	FAO Statistics Division, http://www.fao.org/es/ess/compendium_2004/concepts.asp
Agricultural tractors, total	Agricultural tractors, total generally refer to total wheel, crawler or track-laying type tractors and pedestrian tractors used in agriculture. Data are available for numbers in use in the agricultural sector as of 2000. Data on import and export in value and number are also available as of 1961.	FAO Statistics Division
Agricultural trade	Refers to imports and exports of food and agriculture products, excluding fishery and forestry products. The aggregated item “Agriculture products, Total” (FAOSTAT item code 1882) includes only the food and agriculture products.	FAO Statistics Division
Agriculture producer price index (APPI)	The FAO indices of agricultural producer prices measure the average annual change over time in the selling prices received by farmers (prices at the farm-gate or at the first point of sale). The indices are constructed using the Laspeyres formula with price data in Standardised Local Currency (SLC). This is an aggregate index for primary crops and livestock products. For a country, the aggregate would include primary crops and livestock products that are produced in that country, and for which both production and producer price data are available.	FAO Statistics Division
Agriculture, value added	Agriculture corresponds to the divisions 1-5 of the International Standard Industrial Classification (ISIC, revision 3) and includes forestry, hunting, and fishing, as well as cultivation of crops and livestock production. Value added is the net output of a sector after adding up all outputs and subtracting intermediate inputs. It is calculated without making deductions for depreciation of fabricated assets or depletion and degradation of natural resources. The origin of value added is determined by the International Standard Industrial Classification (ISIC), revision 3. Data are in current or constant US dollars.	World Bank, World Development Indicators
Ammonia, anhydrous	(NH₃) is a material mostly produced by the synthetic process and at standard temperature and pressure is a gas. Fertilizer grade anhydrous ammonia contains about 82% of nitrogen.	FAO Statistics Division
Ammonium nitrate	(NH₄NO₃), is produced by neutralizing nitric acid (HNO₃) with ammonia (NH₃). Ammonium nitrate may be in white or off-white granular or prilled form and coated with a suitable material to prevent absorption of moisture and caking in storage. Pure ammonium nitrate may have a total nitrogen content of about 35%, of which one-half is present as ammoniac nitrogen and the other half as nitrate nitrogen.	FAO Statistics Division
Ammonium sulphate	(NH₄)₂SO₄, is produced by reacting ammonia with sulphuric acid (H₂SO₄). It is produced as fine white granules or crystals and contains not less than 20.6% nitrogen in ammoniac form.	FAO Statistics Division
Arable and Permanent Crops	Arable land and Permanent crops, this land category is the sum of areas under “Arable land” and "Permanent crops”. Data are expressed in 1000 hectares.	FAO Statistics Division
Arable land	Arable land is the land under temporary agricultural crops (multiple-cropped areas are counted only once), temporary meadows for mowing or pasture, land under market and kitchen gardens and land temporarily fallow (less than five years). The abandoned land resulting from shifting cultivation is not included in this category. Data for “Arable land” are not meant to indicate the amount of land that is potentially cultivable. Data are expressed in 1000 hectares.	FAO Statistics Division
Arable land area certified organic	Part of the area of the "Arable land" exclusively dedicated to organic agriculture and managed by applying organic agriculture methods. It is the portion of land area managed (cultivated) or wild harvested in accordance with specific organic standards or technical regulations and that has been inspected and approved by a certification body.	FAO Statistics Division
Arable land area in conversion to organic	Part of the area of the "Arable land" which is going through the organic conversion process, usually two years period of conversion to organic land.	FAO Statistics Division
Arable land organic, total	Sum of areas under “Agricultural area certified organic” and "Arable land area in conversion to organic”.	FAO Statistics Division
Area frame	A sampling frame wherein the sampling units are portions of land, called segments.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Area harvested	Data refer to the area from which a crop is gathered. Area harvested, therefore, excludes the area from which, although sown or planted, there was no harvest due to damage, failure, etc. It is usually net for temporary crops and some times gross for permanent crops. Net area differs from gross area insofar as the latter includes uncultivated patches, footpaths, ditches, headlands, shoulders, shelterbelts, etc. If the crop under consideration is harvested more than once during the year as a consequence of successive cropping (i.e. the same crop is sown or planted more than once in the same field during the year), the area is counted as many times as harvested. On the contrary, area harvested will be recorded only once in the case of successive gathering of the crop during the year from the same standing crops. With regard to mixed and associated crops, the area sown relating to each crop should be reported separately. When the mixture refers to particular crops, generally grains, it is recommended to treat the mixture as if it were a single crop; therefore, area sown is recorded only for the crop reported.	FAO Statistics Division
Area measurement	Refers to the operation of measuring the size of fields (i) on the ground, using measuring tapes and other instruments such as compass, clinometer, etc. or (ii) using remote sensing (aerial or satellite) images.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Area sown	Refers to the area on which sowing or planting has been carried out, for the crop under consideration, on the soil prepared for that purpose. The area is usually reported net of uncultivated patches, footpaths, ditches, headlands, shoulders, shelterbelts, etc. For tree crops, the gross concept may be applied. With regard to mixed and associated crops, countries are requested to report the area sown for each crop separately. When the mixture refers to particular crops, generally grains, it is recommended to treat the mixture as if it were a single crop. Data are recorded in hectares (ha). The information on area sown allows for a particular application of the SUA system where the quantity allotted for next year’s sowing, which enters the account of this year, is calculated as a seeding rate times the area sown of the next year.	FAO Statistics Division
Associated or mixed cropping	Associated crops are those sown interplanted with other temporary or permanent crops, for example, beans and maize. This way of cultivation is widely used in many African countries, particularly for food crops.	FAO. 2001. Food balance sheets. A handbook. Rome.
Balers	Balers (including pickup balers) are machines that collect grass, hay or straw after it has been cut. They form a round or square bale by compressing the material or tying it with twine wire, or a plastic wrap. Data are expressed in numbers in use in the agricultural sector.	FAO Statistics Division
Base year	The starting year for the inventory. Currently this is typically 1990.	IPCC. 2006. 2006 IPCC Guidelines for National Greenhouse Gas Inventories, Prepared by the National Greenhouse Gas Inventories Programme, Eggleston H.S., Buendia L., Miwa K., Ngara T. and Tanabe K. (Eds), IGES, Hayama, Japan.
Biological production	Biological production is production still on the plants. It is one of the three main concepts of production (and yield) used by countries when reporting to FAO.	FAO. 2001. Food balance sheets. A handbook. Rome.
Body mass index (BMI)	The indicator of weight adequacy in relation to height of older children, adolescents and adults. It is calculated as weight (kilograms) divided by height (metres), squared. The acceptable range for adults is 18.5 to 24.9 , and for children it varies with age.	Human energy requirement (Joint FAO/WHO/UNU Expert Consultation), 2001
Calcium ammonium nitrate	NH₄NO₃+CaCO₃, is produced from ammonium nitrate and finely pulverized calcium carbonate (CACO₃). It contains not less than 20.5% and up to 28% of nitrogen, half of which is in the form of ammoniac nitrogen and the other half in the form of nitrate nitrogen. It is produced as white, off-white or grey granules or prills.	FAO Statistics Division
Capital stock in agriculture and investment in agriculture	The estimate of capital stock in agriculture refers to a value that is attached to the total physical capital capacity available for repeated use in the production of other goods, in existence at specific point in time in the economy of agriculture sector. The estimates of investment in agriculture have indirectly been derived by the FAO Statistics Division using physical data on livestock, tractors, irrigated land and land under permanent crops etc., and the average prices for the year 1995. These data enabled the derivation of the capital stock in agriculture which is the gross, and the annual change in the latter is taken to reflect investment in agriculture.	FAO Statistics Division
Carbon dioxide equivalent	A measure used to compare different greenhouse gases based on their contribution to radiative forcing. The UNFCCC currently (2005) uses global warming potentials (GWPs) as factors to calculate carbon dioxide equivalent (see below).	IPCC. 2006. 2006 IPCC Guidelines for National Greenhouse Gas Inventories, Prepared by the National Greenhouse Gas Inventories Programme, Eggleston H.S., Buendia L., Miwa K., Ngara T. and Tanabe K. (Eds), IGES, Hayama, Japan.
Census committee	An inter-ministerial or inter-agency committee consisting of high-level personnel with main responsibilities consisting of the overall planning and direction of the census, in cooperation with and/or subject to the review of the census coordinator.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Census pre-tests	Usually small-scale exercises for evaluating specific aspects of the census during the preparatory phase.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Cereal food aid shipments	Food aid shipments represent a transfer of food commodities from donor to recipient countries on a total-grant basis. Processed and blended cereals are converted into their grain equivalent by applying the conversion factors included in the Rule of Procedures under the 1999 Food Aid Convention to facilitate comparisons between deliveries of different commodities.	From 1970/71 to 1990/91, data on food aid shipments was compiled by FAO from the information provided by donor countries, and complemented by data provided by the FAO Consultative Sub-Committee on Surplus Disposal, the World Food Programme (WFP), the International Wheat Council, OECD, and other international organizations. From 1990/91 to date, the information on food aid shipments has been provided to FAO exclusively by WFP.
Child mortality rate (infant mortality rate)	The infant mortality rate is the probability (expressed as a rate per 1 000 live births) of a child born in a specified year dying before reaching the age of one if subject to current age-specific mortality rates.	World Development Indicators
Child mortality rate (under-five mortality rate)	The under-five mortality rate is the probability (expressed as a rate per 1 000 live births) of a child born in a specified year dying before reaching the age of five if subject to current age-specific mortality rates.	World Development Indicators
CIF	Cost-Insurance-Freight. CIF-trade values include the transaction value of the goods, the value of services performed to deliver goods to the border of the exporting country and the value of the services performed to deliver the goods from the border of the exporting country to the border of the importing country. Import values are mostly reported as CIF.	UNSD. 2004. International Merchandise Trade Statistics: Compilers Manual. New York.
Combine harvesters – threshers	Combine harvesters - threshers are self-propelled machines that collect and thresh in one operation. Data are expressed in numbers in use in the agricultural sector.	FAO Statistics Division
Commodity code	Trade statistics are usually reported according to the Harmonized Commodity Description and Coding System (HS), which is an international commodity classification developed under the auspices of the Customs Cooperation Council. The standard HS codes contain six digits, but can be extended to eight, ten or twelve digits according to national tariff and statistical needs. The conversion of the HS codes into FAOSTAT codes is based on a specific conversion table used during trade data processing.	- UNSD. 2004. International Merchandise Trade Statistics: Compilers Manual. New York. - FAO Statistics Division
Confidentiality	Refers to the legal obligation of the census staff not to reveal the individual holding data to anyone, neither in the form of raw data nor in the form of tables which may permit disclosure of data for individual holdings. Obligation to respond is often linked to and legitimized by confidentiality as a guarantee for the respondent.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Consumer price index (CPI)	The CPI measures changes over time in the general level of prices of consumer goods and services that households acquire, use or pay for consumption. This is done by measuring the cost of purchasing a fixed basket of consumer goods and services of constant quality and similar characteristics, with the products in the basket being selected to be representative of households’ expenditure during a specified period.	International Labour Organization (ILO)
Continuous harvesting	Refers to crops which are harvested continuously throughout the season, such as carrots radishes, sweet potatoes, etc., or crops which are standing in the field more than a year, like sugar cane. The estimation of their production has to include all the harvest during the year.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Country area	Country area, area of the country including area under inland water bodies, but excluding offshore territorial waters. Possible variations in the data may be due to updating and revisions of the country data and not necessarily to any change of area. Data are expressed in 1000 hectares.	FAO Statistics Division
Coverage	Describes the universe of units to be enumerated; it can include rural and urban areas. Under predefined thresholds, in physical terms or in value, very small holdings may be excluded from the census.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Crop area	Crop area is a surface of land on which a crop is grown. In general, the area measured for cadastral purposes includes, in addition to the area cultivated, headlands, ditches and other non-cultivated areas. Such an area can be called gross area as against the net area which includes only the portion of the gross area actually cultivated. For various reasons, e.g. natural calamities or economic considerations, certain areas planted or sown with a given crop are not harvested or are harvested before the crop reaches maturity. Hence the need for the concept of area to be sub-divided into sown or planted area and harvested area. Sown area data are necessary to estimate quantities used for seeding purposes; harvested area, to provide reliable and accurate yield and production data. A peculiarity of permanent crops is that number of trees or plants is reported in addition to or, instead of, the area planted. This is particularly so as regards plants growing outside of compact plantations, which are either interplanted with other crops or are scattered. Both area and number of trees are also divided into productive or bearing and non-productive or non-bearing areas or trees. In most cases, non-bearing refers to young plants that are not yet bearing.	FAO. 2001. Food balance sheets. A handbook. Rome.
Crop production	Crop production data refer to the actual harvested production from the field or orchard and gardens, excluding harvesting and threshing losses and that part of crop not harvested for any reason. Production therefore includes the quantities of the commodity sold in the market (marketed production) and the quantities consumed or used by the producers (auto-consumption). When the production data available refers to a production period falling into two successive calendar years and it is not possible to allocate the relative production to each of them, it is usual to refer production data to that year into which the bulk of the production falls. Crop production data are recorded in tonnes (t). In many countries, crop production data are obtained as a function of the estimated yield and the total area. If such a compilation method of production statistics is enforced by the country, it must be ensured that the total area does not refer to sown or planted area, which would give then the ‘biological production’, but to the actually harvested area during the year.	FAO Statistics Division
Crop yield	Harvested production per unit of harvested area for crop products. In most of the cases yield data are not recorded but obtained by dividing the production data by the data on area harvested. Data on yields of permanent crops are not as reliable as those for temporary crops either because most of the area information may correspond to planted area, as for grapes, or because of the scarcity and unreliability of the area figures reported by the countries, as for example for cocoa and coffee.	FAO Statistics Division
Crops cultivated simultaneously	Refers to the practice of cultivating two or more different crops simultaneously on the same field or plot. If crops grown simultaneously are temporary and permanent crops together, they are called crops grown in association. Otherwise they are referred to as mixed crops.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Customs value	The definition of the customs value of goods normally covers the transaction value plus the value of the services performed to deliver goods to the border of the importing/exporting country. Whenever this is the case, the customs value should be accepted as the statistical value; in all other cases the compiler should make the necessary adjustments to available customs values or independently estimate statistical value.	UNSD. 2004. International Merchandise Trade Statistics: Compilers Manual. New York.
Data coding	Refers to the operation where original information from the questionnaire, as recorded by enumerators, is replaced by a numeric code required for processing. Typical examples are when names of crops, livestock, farm machinery, activities etc. are replaced by a unique number (code) or when data expressed in local units are converted to a standard unit. The modern trend is either to enter the complete answer or to use precoded questionnaires and leave the problem of local units to enumerators who are expected to enter in the questionnaires data ready for processing.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Data editing	Refers to checking (manually or by computer) the general credibility of the data with respect to (i) missing data, (ii) range tests, and (iii) logical and/or numerical consistency. Examples could be: (i) non-response (e.g. age of the holder not reported); (ii) improbable or impossible entries (e.g. yield is hundred times higher than normal, etc.).	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Diammonium phosphate (DAP)	(NH₄)₂HPO₄, is produced by evaporating a solution of phosphoric acid with excess of ammonia.	FAO Statistics Division
Dietary energy consumption per person	Dietary energy consumption per person refers to the amount of food, expressed in kilocalories (kcal) per day, available for each individual in the total population during the reference period. Caloric content is derived by applying the appropriate food composition factors to the quantities of the commodities. Per person supplies are derived from the total amount of food available for human consumption by dividing total calories by total population actually partaking of the food supplies during the reference period. However, per person figures represent only the average supply available for the population as a whole and do not necessarily indicate what is actually consumed by individuals. The actual food consumption may be lower than the quantity shown as food availability depending on the magnitude of wastage and losses of food in the household, e.g. during storage, in preparation and cooking, as plate-waste or quantities fed to domestic animals and pets, thrown or given away.	FAO Statistics Division
Dietary energy deficit	The difference between the average daily dietary energy intake of an undernourished population and its average minimum energy requirement.	FAO 1996 - The Sixth World Food Survey
Dietary energy excess	The difference between the average daily dietary energy intake of an overnourished population and its average maximum energy requirement.	FAO 1996 - The Sixth World Food Survey
Dietary energy requirement	Energy requirement is the amount of food energy needed to balance energy expenditure in order to maintain body size, body composition and to allow optimal growth and development of children, deposition of tissues during pregnancy and secretion of milk during lactation, consistent with long-term good health.	Human energy requirement (Joint FAO/WHO/UNU Expert Consultation), 2001
Dietary fat consumption per person	Dietary fat consumption per person refers to the amount of fat in food, expressed in grams per day, available for each individual in the total population during the reference period. Fat content is derived by applying the appropriate food composition factors to the quantities of the commodities. Per person consumption is derived from the total amount of food available for human consumption by dividing total fat by total population actually partaking of the food supplies during the reference period. However, per person figures represent only the average supply available for the population as a whole and do not necessarily indicate what is actually consumed by individuals. The actual food consumption may be lower than the quantity shown as food availability depending on the magnitude of wastage and losses of food in the household, e.g. during storage, in preparation and cooking, as plate-waste or quantities fed to domestic animals and pets, thrown or given away.	FAO Statistics Division
Dietary protein consumption per person	Dietary protein consumption per person refers to the amount of protein in food, expressed in grams per day, available for each individual in the total population during the reference period. Protein content is derived by applying the appropriate food composition factors to the quantities of the commodities. Per person consumption is derived from the total amount of food available for human consumption by dividing total protein by total population actually partaking of the food supplies during the reference period. However, per person figures represent only the average supply available for the population as a whole and do not necessarily indicate what is actually consumed by individuals. The actual food consumption may be lower than the quantity shown as food availability depending on the magnitude of wastage and losses of food in the household, e.g. during storage, in preparation and cooking, as plate-waste or quantities fed to domestic animals and pets, thrown or given away.	FAO Statistics Division
Domestic goods	Domestic goods are goods originating in the economic territory of a country, while foreign goods are goods which originate from the rest of the world. Determination of the origin of goods in each compiling country is made in accordance with national rules. It is recognized that these rules may lead to different attributions of origin and to incompatibilities in partner statistics. The harmonization of rules of origin is, therefore, one of the important challenges to customs and statistical authorities.	UNSD. 2004. International Merchandise Trade Statistics: Compilers Manual. New York.
Domestic supply	Production + imports - exports + changes in stocks (decrease or increase) = supply for domestic utilization. There are various ways of defining supply and, in fact, various concepts are in use. The elements involved are production, imports, exports and changes in stocks (increase or decrease). There is no doubt that production, imports and stock changes (either decrease or increase in stocks) are genuine supply elements.	FAO Statistics Division
Economic territory	Economic territory of a country consists of the geographic territory administered by a government within which persons, goods and capital circulate freely and includes: (a) airspace, territorial waters, and continental shelf lying in international waters over which the country enjoys exclusive rights or over which it has, or claims to have, jurisdiction in respect of the right to fish or to exploit fuels or minerals below the seabed; (b) territorial enclaves in the rest of the world (clearly demarcated areas of land which are located in other countries and which are used by the government which owns or rents them for diplomatic, military, scientific or other purposes - embassies, consulates, military bases, scientific stations, information or immigration offices, aid agencies, etc. - with the formal political agreement of the government of the country in which they are physically located). Goods or persons may move freely between a country and its territorial enclaves abroad, but become subject to control by the government of the country in which they are located if they move out of the enclave; (c) any free zones, or bonded warehouses or factories operated by offshore enterprises under customs control (these form part of the economic territory of the country in which they are physically located). In the case of maritime countries, their economic territory includes any islands belonging to that country which are subject to exactly the same fiscal and monetary authorities as the mainland, so that goods and persons may move freely to and from such islands without any kind of customs or immigration formalities. The economic territory of a country does not include the territorial enclaves used by foreign governments or international organizations that are physically located within the geographical boundaries of that country.	- UNSD. 2004. International Merchandise Trade Statistics: Compilers Manual. New York. - 1993 System of National Accounts, paragraph 14.9.

Fallow land	Fallow land (temporary) is the cultivated land that is not seeded for one or more growing seasons. The maximum idle period is usually less than five years. Land remaining fallow for two long may acquire characteristics requiring to be reclassified, such as "permanent meadows and pastures" (if used for grazing), "forest or wooded land" (if overgrown with trees), or "other land" (if it becomes wasteland). Data are expressed in 1000 hectares.	FAO Statistics Division
Feed	Data refer to the quantity of the commodity in question available for feeding to the livestock and poultry during the reference period, whether domestically produced or imported.	FAO. 1986. The ICS users' manual. Interlinked computer strorage and processing system of food and agricultural commodity data. Rome.

Food from milk relates to the amounts of milk as such, as well as the fresh milk equivalent of dairy products.	FAO. 1986. The ICS users' manual. Interlinked computer strorage and processing system of food and agricultural commodity data. Rome.
Food aid	Food aid represent a transfer of food commodities from donor to recipient countries on a total-grant basis or on highly concessional terms.	From 1970/71 to 1990/91, data on food aid shipments was compiled by FAO from the information provided by donor countries, and complemented by data provided by the FAO Consultative Sub-Committee on Surplus Disposal, the World Food Programme (WFP), the International Wheat Council, OECD, and other international organizations. From 1990/91 to date, the information on food aid shipments has been provided to FAO exclusively by WFP.
Food aid received	Refers to food aid shipments which represent a transfer of food commodities from donor to recipient countries on a total-grant basis or on highly concessional terms. A food aid shipment record contains information on the year of shipment, donor, recipient, commodity and quantity in terms of thousand tonnes (t). Cereal food aid shipments are reported on a global trade year basis (July/June). The series starts from 1970/71. Processed and blended cereals are converted into their grain equivalent by applying the conversion factors included in the Rule of Procedures under the 1999 Food Aid Convention to facilitate comparisons between deliveries of different commodities.	From 1970/71 to 1990/91, data on food aid shipments were compiled by FAO from the information provided by donor countries and complemented by data provided by the FAO Consultative Sub-Committee on Surplus Disposal, the World Food Programme (WFP), the International Wheat Council, OECD and other international organizations. From 1990/91 to date, the information on food aid shipments has been provided to FAO exclusively by WFP.
Food Balance Sheets	Food Balance Sheets (FBS) are compiled every year by FAO, mainly with country-level data on the production and trade of food commodities. Using these data and the available information on seed rates, waste coefficients, stock changes and types of utilization (feed, food, processing and other utilization), a supply/utilization account is prepared for each commodity in weight terms. The food component of the commodity account, which is usually derived as a balancing item, refers to the total amount of the commodity available for human consumption during the year. Besides commodity-by-commodity information, the FAO FBS also provide total food availability estimates by aggregating the food component of all commodities including fishery products. From these values and the available population estimates, the per person dietary energy and protein and fat supplies are derived and expressed on a daily basis. In the FBS production data refer only to primary products while data for all other elements also include processed products derived there from, expressed in primary commodity equivalent.

Food Consumer Price Index (Food CPI)	The Food CPI measures the change over time in the general level of prices of food and non-alcoholic beverage items that households acquire, use or pay for consumption. This is done by measuring the cost of purchasing a fixed basket of consumer food and beverage of constant quality and similar characteristics, with the products in the basket being selected to be representative of households’ expenditure during a specified period.	International Labour Organization (ILO)
Food consumption per person by food group	Food consumption per person is the amount of food, in terms of quantity, of each commodity and it's derived products for each individual in the total population. Figures are shown for food groups.	FAO Statistics Division, http://www.fao.org/faostat/foodsecurity/FSSDMetadata_en.htm
Food consumption per person by food item	Food consumption per person is the amount of food, in terms of quantity, of each commodity and it's derived products for each individual in the total population. Figures are shown for food items.	FAO Statistics Division, http://www.fao.org/faostat/foodsecurity/FSSDMetadata_en.htm
Food insecurity	A situation that exists when people lack secure access to sufficient amounts of safe and nutritious food for normal growth and development and an active and healthy life. It may be caused by the unavailability of food, insufficient purchasing power, inappropriate distribution, or inadequate use of food at the household level. Food insecurity, poor conditions of health and sanitation, and inappropriate care and feeding practices are the major causes of poor nutritional status. Food insecurity may be chronic, seasonal or transitory.	FAO. 2000. The state of food insecurity in the world - SOFI 2000. Rome.
Food production	For primary commodities, production relates to the total domestic production whether inside or outside the agricultural sector, i.e. including non-commercial production and production in kitchen gardens. Unless otherwise indicated, production is reported at the farm level for primary crops (i.e. excluding harvesting losses for crops) and livestock items and in terms of live weight (i.e. the actual ex-water weight of the catch at the time of capture) for primary fish items. Production of processed commodities relates to the total output of the commodity at the manufacture level (i.e. it comprises output from domestic and imported raw materials of originating products). Reporting units are chosen accordingly, e.g. cereals are reported in terms of grains and paddy rice. As a general rule, all data on meat are expressed in terms of carcass weight. Usually the data on production relate to that which takes place during the reference period. However, production of certain crops may relate to the harvest of the year preceding the utilization period if harvesting takes place late in the year. In such instances, the production of a given year largely moves into consumption in the subsequent year. In the Food Balance Sheets a distinction is made between "output" and "input". The production of primary as well as of derived products is reported under "output". For derived commodities, the amounts of the originating commodity that are required for obtaining the output of the derived product are indicated under "input", and are expressed in terms of the originating commodity. The various factors used, i.e. milling rates, extraction rates, conversion or processing factors, carcass weights, milk yield, egg weights etc., should indicate the average national rate at which these commodities are generally converted.

It does not include land that is predominantly under agricultural or urban land use. Forest is determined both by the presence of trees and the absence of other predominant land uses. The trees should be able to reach a minimum height of 5 metres (m) in situ. Areas under reforestation that have not yet reached but are expected to reach a canopy cover of 10 percent and a tree height of 5 m are included, as are temporarily unstocked areas, resulting from human intervention or natural causes, which are expected to regenerate. Includes: areas with bamboo and palms provided that height and canopy cover criteria are met; forest roads, firebreaks and other small open areas; forest in national parks, nature reserves and other protected areas such as those of specific scientific, historical, cultural or spiritual interest; windbreaks, shelterbelts and corridors of trees with an area of more than 0.5 ha and width of more than 20 m; plantations primarily used for forestry or protective purposes, such as: rubber-wood plantations and cork, oak stands. Excludes: tree stands in agricultural production systems, for example in fruit plantations and agroforestry systems. The term also excludes trees in urban parks and gardens.

GDP	Gross domestic product
General trade	The general trade system is in use when statistical territory of a country coincides with its economic territory. Consequently, under the general trade system, imports include all goods entering the economic territory of a compiling country and exports include all goods leaving the economic territory of a compiling country, including re-exports and imports into and exports from customs warehouses and free zones or ports.	UNSD. 2004. International Merchandise Trade Statistics: Compilers Manual. New York.
Gini index	Gini index measures the extent to which the distribution of income (or, in some cases, consumption expenditure, food dietary energy consumption) among individuals or households within an economy deviates from a perfectly equal distribution. A Lorenz curve plots the cumulative percentages of total income received against the cumulative number of recipients, starting with the poorest individual or household. The Gini index measures the area between the Lorenz curve and a hypothetical line of absolute equality, expressed as a percentage of the maximum area under the line. Thus a Gini index of 0 represents perfect equality, while an index of 100 implies perfect inequality.	WDI 2004
Global warming potential	Global Warming Potentials (GWP) are calculated as the ratio of the radiative forcing of one kilogramme greenhouse gas emitted to the atmosphere to that from one kilogramme CO2 over a period of time (e.g., 100 years).

(Eds), IGES, Hayama, Japan.
GNP	Gross National Product
Good Practice	Good Practice is a set of procedures intended to ensure that greenhouse gas inventories are accurate in the sense that they are systematically neither over- nor underestimates so far as can be judged, and that uncertainties are reduced so far as possible. Good Practice covers choice of estimation methods appropriate to national circumstances, quality assurance and quality control at the national level, quantification of uncertainties and data archiving and reporting to promote transparency.

Responsibilities are limited to making day-to-day decisions to operate the holding, including managing and supervising hired labour. Wages may be paid in cash and/or kind. A hired manager who shares economic and financial responsibilities, in addition to managing the holding, should be considered a holder or a joint holder.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Holder	A civil or juridical person who makes major decisions regarding resource use and exercises management control over the agricultural operation. The holder has technical and economic responsibility for the holding and may undertake all responsibilities directly or delegate responsibilities related to day-to-day work management to a hired manager.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Holding	See agricultural holding.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Household	A household may be either: (a) a one-person household, i.e. a person who makes provision for his own food and other essentials of living without combining with any other person, or (b)a multi-person household, i.e. a group of two or more persons who make some common provision for food or other essentials of living. The persons in the group may pool their incomes and have a common budget to a greater or lesser extent; they may be related or unrelated persons or a combination of both. The general criterion to be used in identifying the members of a multi-person household relates to the existence of common housekeeping arrangements.	International Labour Organisation (ILO), Thirteenth International Conference of Labour Statisticians
Household consumption expenditure	Household consumption expenditure refers to all money expenditure by the household and individual members on goods intended for consumption and expenditure on services, plus the value of goods and services received as income in kind and consumed by the household or individual members of the household. Thus the value of items produced by the household and utilised in its own consumption, the net rental value of owner-occupied housing and the gross rental value of free housing occupied by the household represent part of household consumption expenditure.	International Labour Organization (ILO), Thirteenth International Conference of Labour Statisticians
Import dependency ratio	Import dependency ratio (IDR) is defined as: IDR = imports*100/(production + imports - exports). The complement of this ratio to 100 would represent that part of the domestic food supply that has been produced in the country itself. However, there is a caveat to be kept in mind: these ratios hold only if imports are mainly used for domestic utilization and are not re-exported.	FAO. 2001. Food balance sheets. A handbook. Rome.
Imputation	A term used in data processing indicating replacement of individual data which are either not consistent or missing.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.

Inland water	Inland water is the area occupied by major rivers, lakes and reservoirs. Data are expressed in 1000 hectares.	FAO Statistics Division
International Dollar prices	International Dollar prices are international prices expressed in a common currency (usually the US Dollar, hence their name) that were developed within the framework of GDP international comparisons. International prices are useful in computing comparable value aggregates for different commodities groups. They also form a basic input to the computation of FAO’s Laspeyres-type production index numbers which use the concept of constant price comparisons. Inter-country comparison of aggregates and resulting index numbers hinges largely on the choice of an appropriate methodology for determining international prices. Details on theory, methodology and interpretation of international comparisons and international prices are discussed at length in many articles and ICP reports. Reported below are the main steps in the calculation of international prices. International prices are a function of production of the different commodities in different countries, of their national prices and of the exchange rates between national currencies. These functions must satisfy some (mathematical) feasibility requirements and some criteria that ensure the economic significance of the results. The main methods that satisfy most requirements (Geary-Khamis, Gerardi, EKS, etc.) can be divided into two main categories: those methods that derive international prices and exchange rates directly from price and quantity data and methods that construct price index numbers directly from which, in turn, implicit exchange rates can be calculated. The Geary-Khamis approach that has been chosen by the UN to define the international prices and exchange rates derived from the data through a system of interdependent equations. In the equation system international prices of commodities are weighted averages of national prices converted into a common currency and weighted by national outputs. Exchange rates are equal to the ratio of the value of production of a given country at international prices divided by the value of production of the same country in national currency. When one currency is chosen as the numeraire, the system can be solved and has a unique solution. Exchange rates of the other currencies and international prices can be expressed in terms of the currency chosen as the reference. The set of international prices and exchange rates thus obtained can enter directly the computation of price and quantity index numbers.	FAO Statistics Division
International dollars	In aggregating production of commodities that cannot be added up with their physical weight, for example cereals and cotton, and also to make regional totals without using official exchange rates to US dollars, or to any other currency, which are often misleading, particularly for developing countries, the aggregation of production has been made on the basis of the value of commodities by using ''international commodity prices''. Those prices result from the iterative comparison, through mathematical methods, of the production value of all commodities in all countries, obtained from the producer prices of each commodity/country, with the corresponding value of production in the United States obtained in a similiar manner. With the operation, both special exchange rates to US dollars for each country and thereby special commodity prices for each commodity are obtained: The so called ''International dollars''. Thus, the method assigns a single price to each commodity and country. For example, 1 ton of maize has the same price in whichever country it is produced. As both production and producer prices entering in the game are those of the average 2004-2006, it can be said that those prices are the average of prices in different countries, around 2005, after converting them into a common currency unit. Therefore the Indices indicate fairly well production trends as prices are not based on official exchange rates to US dollars but on special exchange rates derived from the Geary-Khamis formula. While official exchange rates are much influenced by sectors (industry, services, finance, etc) which have nothing to do with the agricultural sector, the Geary-Khamis formula takes into account only the agricultural sector.

Killed weight	Killed weight is the gross weight of the carcass including the hide or skin, head, feet and internal organs, but excluding the part of the blood which is not collected in the course of slaughter.
Kilocalorie (kcal)	Unit of measurement of dietary energy. It should be noted that in accordance to International System of Units, energy is measured in joules, J, but the customary usage of thermochemical energy units of kilocalories (kcal) is mostly used. 1 kcal = 4.184 kJ.	Human energy requirement (Joint FAO/WHO/UNU Expert Consultation), 2001
Labour force	All those employed (including people above a specified age who, during the reference period, were in paid employment, at work, sel-employed or with a job but not at work) and unemployed (including people above a specified age who, during the reference period, were without work, currently available for work and seeking work).	International Labour Organisation (ILO). 1996. Economically Active Population 1950-2010: Fourth edition. Geneva.

Laspeyres formula	The index is calculated by summing the Standardised Local Currency (SLC) price for a given year multiplied by production quantity in base year for all items in the aggregate and dividing by the sum of the SLC price in the base year multiplied by production quantity for the base year for the same items. The single item indices are calculated by dividing the SLC price in a given year by the SLC price in the base year.	FAO Statistics Division

Maximum dietary energy requirement	In a specified age and sex group, the amount of dietary energy per person that is considered adequate to meet the energy needs for heavy activity and good health. In an entire population, the maximum energy requirement is the weighted average of the maximum energy requirements of the different age and sex groups in the population. This is expressed in kilocalories per person per day.	FAO Statistics Division
Milk production	Production data of milk indicates the quantity of milk produced during the year from the animals of the species to which the Supply Utilization Accounts refer. Milk production data is reported according to the concept of net milk production: total production of whole fresh milk, excluding the milk sucked by young animals but including amounts fed to livestock.

Nomadic animals	Nomadic animals are those without any fixed installation which continually or periodically shift from place to place. The phenomenon of nomadism exists in Africa and in the Near East. In areas where nomadism is practised, livestock may be enumerated twice, or may not be enumerated at all if enumerators fail to pay sufficient attention to this livestock-rearing practice.	FAO. 2001. Food balance sheets. A handbook. Rome.
Nomadic livestock	Refers to animals kept by households with no permanent place of residence who are forced by natural circumstances, such as scarcity of water and pastures, or because of climatic conditions to move from place to place. The enumeration of such holdings presents special problems.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Non-agricultural population	The non-agricultural population is obtained as a residual of agricultural population from the total population.	FAO Statistics Division
Non-cereal food aid shipments	Non-cereal commodities or commodity groups include skimmed milk powder, vegetable oil, butter oil, other dairy products, meat, fish, pulses, sugar, dried fruit and other foodstuffs. From 1977 to 1986, because of the non-availability of data, non-cereal food aid is composed of four commodities only: skimmed milk powder, vegetable oil, butter oil and other dairy products.	From 1970/71 to 1990/91, data on food aid shipments was compiled by FAO from the information provided by donor countries, and complemented by data provided by the FAO Consultative Sub-Committee on Surplus Disposal, the World Food Programme (WFP), the International Wheat Council, OECD, and other international organizations. From 1990/91 to date, the information on food aid shipments has been provided to FAO exclusively by WFP.

Number of live animals	This variable indicates the number of animals of the species present in the country at the time of enumeration. It includes animals raised either for draft purposes or for meat, eggs and dairy production or kept for breeding. Live animals in captivity for fur or skin such as foxes, minks etc. are not included in the system although furskin trade is reported. The enumeration to be chosen, when more than one survey is taken, is the closest to the beginning of the calendar year. Livestock data are reported in number of heads (units) except for poultry, rabbits and other rodents which are reported in thousand units.	FAO Statistics Division
Number of overnourished people	Number of persons with food intake that is in excess of maximum dietary energy requirements continuously.	FAO Statistics Division
Number of undernourished people	Number of people in a condition of undernourishment. The number of persons undernourished is obtained by multiplying estimates of the proportion of undernourished for each country by estimates of the total population. Undernourishment refers to the condition of people whose dietary energy consumption is continuously below a minimum dietary energy requirement for maintaining a healthy life and carrying out a light physical activity.	FAO Statistics Division
Nutritional status	The physiological state of an individual that results from the relationship between nutrient intake and requirements and from the body’s ability to digest, absorb and use these nutrients.	FAO. 2000. The state of food insecurity in the world (SOFI -2000). Rome.
Opening stocks	Data refer to the quantities in stocks available at the beginning of the reference period irrespective of its origin, i.e. domestic production or imports. In principle, this should include stocks held at various levels between the farm and the level at which "final consumption" of the commodity is measured. In this sense, government stocks, stocks with manufacturers, importers, exporters and other wholesale merchants, transport and storage enterprises and stock on farms are included. A basic element of an account concerns volumes of the product under consideration at a specific point in time, most often expressed in terms of weight, in tonnes (1 000 kilograms). In practice, comprehensive and reliable data are rarely available, therefore the Supply Utilization Accounts make use of the stock variation rather than levels.	FAO Statistics Division
Other Agricultural tractors	Other agricultural tractors include all other agricultural tractors that are not pedestrian controlled or track-lying, e.g. 4-wheel, 6-wheel, etc. Data are expressed in numbers in use in the agricultural sector.	FAO Statistics Division

Other NP compound may also include some AN grades with small amounts of phosphates.	FAO Statistics Division
Other nitrogen & phosphorus compounds	Can be produced as the result of a chemical reaction of nitric acid on phosphate rock, with or without added ammonia and/or phosphoric and/or sulfuric acid or between sulfuric acid and ammonia. or by simple mechanical mixing or blending. Other NP compound may also include some AN grades with small amounts of phosphates.	FAO Statistics Division
Other utilization	Data refer to quantities of commodities used for non-food purposes, e.g. oil for soap. In order not to distort the picture of the national food pattern quantities of the commodity in question consumed mainly by tourists are included here (see also "Per capita supply"). In addition, this variable covers pet food.	FAO. 1986. The ICS users' manual. Interlinked computer strorage and processing system of food and agricultural commodity data. Rome.
Overnourished population	Share of population with food intake that is in excess of maximum dietary energy requirements continuously.	FAO. 2003.

An Inter-agency Initiative to Promote Information and Mapping Systems on Food Insecurity and Vulnerability (FIVIMS). Rome.
Overnourishment	Food intake that is in excess of dietary energy requirements continuously.	FAO. 2000. The state of food insecurity in the world 2000. Rome.
Pedestrian controlled tractors	Pedestrian controlled tractors are small tractors equipped with a single driving axle carried on one or two wheels. They are not usually fitted with a seat and the steering is effected by means of two handles. Some types, however, have a one- or two-wheeled rear carriage with a seat for the driver. Data are expressed in numbers in use in the agricultural sector.	FAO Statistics Division
Per capita supply	Estimates of per capita food supplies available for human consumption during the reference period in terms of quantity, caloric value, protein and fat content. Calorie supplies are reported in kilocalories (1 calorie = 4.19 kilojoules). Per capita supplies in terms of product weight are derived from the total supplies available for human consumption (i.e. Food) by dividing the quantities of Food by the total population actually partaking of the food supplies during the reference period, i.e. the present in-area (de facto) population within the present geographical boundaries of the country. In other words, nationals living abroad during the reference period are excluded, but foreigners living in the country are included. Adjustments are made wherever possible for part-time presence or absence, such as temporary migrants, tourists and refugees supported by special schemes (if it has not been possible to allow for the amounts provided by such schemes under imports). In almost all cases, the population figures used are the mid-year estimates published by the United Nations Population Division. Per capita supply figures shown in the commodity balances therefore represent only the average supply available for the population as a whole and do not necessarily indicate what is actually consumed by individuals. Even if they are taken as approximation to per capita consumption, it is important to note that the amount of food actually consumed may be lower than the quantity shown here, depending on the degree of losses of edible food and nutrients in the household, e.g. during storage, in preparation and cooking etc. In many cases commodities are not consumed in the primary form in which they are presented in the commodity balance, e.g. cereals enter the household mainly in processed form like flour, meal, husked or milled rice. To take this fact into account, the caloric value, the protein and fat content shown against primary commodities in the commodity balances have been derived by applying the appropriate food composition factors to the quantities of the processed commodities and not by multiplying the quantities shown in the commodity balance with the food composition factors relating to primary commodities.	FAO Statistics Division
Permanent crops	Crops are divided into temporary and permanent crops. 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. This category includes flowering shrubs, fruit trees, nut trees and vines, but excludes trees grown for wood or timber.	FAO. 2001. Food balance sheets. A handbook. Rome.
Permanent crops (land use database)	Permanent crops is the land cultivated with long-term crops which do not have to be replanted for several years (such as cocoa and coffee); land under trees and shrubs producing flowers, such as roses and jasmine; and nurseries (except those for forest trees, which should be classified under "forest"). Permanent meadows and pastures are excluded from land under permanent crops. Data are expressed in 1000 hectares.	FAO Statistics Division
Permanent crops area certified organic	Part of the area of the "Permanent crops" exclusively dedicated to organic agriculture and managed by applying organic agriculture methods. It is the portion of land area managed (cultivated) or wild harvested in accordance with specific organic standards or technical regulations and that has been inspected and approved by a certification body.

Pesticide consumption	Data refer to quantities of pesticides applied to crops and seeds in the agriculture sector. Figures are generally expressed in terms of active ingredients. Data are expressed in tonnes (t). However, due to some country reporting practices, the data may be reported by: consumption in formulated product (including diluents and adjuvants); sales; distribution or imports for use in the agricultural sector. In these cases it is specified in the country notes.	FAO Statistics Division
Pesticide trade	Value of trade covering insecticides, fungicides, herbicides, disinfectants and others, as described by the Harmonised Coding System (HS) code 3808. Differences between figures given for total exports and total imports at the world level may be due to several factors, e.g. the time lag between the dispatch of goods from exporting country and their arrival in the importing country; the use of different classification of the same product by different countries; or the fact that some countries supply data on general trade while others give data on special trade. Data refer to the value of the trade expressed in 1000 USD.	FAO Statistics Division
Pesticides	Pesticides refer to insecticides, fungicides, herbicides, disinfectants and any substance or mixture of substances intended for preventing, destroying or controlling any pest, including vectors of human or animal disease, unwanted species of plants or animals causing harm during or otherwise interfering with the production, processing, storage, transport or marketing of food, agricultural commodities, wood and wood products or animal feedstuffs, or substances which may be administered to animals for the control of insects, arachnids or other pests in or on their bodies. The term includes substances intended for use as a plant growth regulator, defoliant, desiccant or agent for thinning fruit or preventing the premature fall of fruit, and substances applied to crops either before or after harvest to protect the commodity from deterioration during storage and transport.	FAO 2005, Summary of world food and agricultural statistics
Phosphate rock	Is a natural rock containing one or more calcium phosphate minerals of sufficient purity and quantity as to permit its use directly after grinding or after chemical processing in the manufacture of commercial phosphate fertilizers.	FAO Statistics Division

Potassium chloride (Muriate of potash)	Is refined from mined, low-grade naturally occurring ores as the mineral sylvite and in combination with sodium chloride as sylvinite. Potassium chloride contains from about 48 to 62 % K₂0.	FAO Statistics Division
Potassium nitrate	KNONH₃H₂PO₄ can be produced from naturally occurring sodium nitrate and potassium chloride and typically contains 13%N and 45% K₂O.	FAO Statistics Division
Potassium sulphate	Is a white crystalline salt and contains 48 to 52 per cent potash (K₂0). Potassium sulfate can be extracted from naturally occurring brines or by the decomposition of potassium chloride with sulfuric acid.	FAO Statistics Division
PPP	A purchasing power parity (PPP) conversion factor is the number of units of a country’s currency required to buy the same amounts of goods and services in the domestic market as U.S. dollar would buy in the United States. Source: World Bank, International Comparison Programme database. The international comparability of prices converted into US Dollars may not be entirely justified because the exchange rates applied may, in practice, only be used for the conversion of a limited number of external transactions and may not be relevant for the much larger portion of GDP covering domestic transactions. The exchange rate simply converts the GDPs into the same currency units. Also, exchange rates are based on short-term factors and are subject to substantial distortions even when averaged over a period of time. PPP’s were introduced to compare GDP aggregates not only in a common currency but at the same price level. PPP’s as published by the World Bank in World Development Indicators are applied.	FAO Statistics Division
Prevalence of overnourished in total population	Proportion of the population in a condition of overnourishment.	FAO. 2003. Proceedings Measurement and assessment of food deprivation and undernutrition. International Scientific Symposium Rome, 26-28 June 2002. An Inter-agency Initiative to Promote Information and Mapping Systems on Food Insecurity and Vulnerability (FIVIMS). Rome.
Prevalence of undernourishment	Proportion of the population in a condition of undernourishment. Undernourishment refers to the condition of people whose dietary energy consumption is continuously below a minimum dietary energy requirement for maintaining a healthy life and carrying out a light physical activity.	FAO Statistics Division
Prices in Agricultural PPP	Prices in Agricultural Purchasing Power Parities (AgPPP) are calculated by converting prices in local currencies into prices in Dollars using Agricultural PPP’s instead of exchange rates. Agriculture Purchasing Power Parities have been calculated to equalise purchasing power across countries based on countries’ agricultural output by applying the Geary-Khamis equation system to agriculture output and prices (FAOSTAT datasets of prices in local currency and production in physical terms). The equations generate to sets of parameters: a set of international prices expressed in a common currency and a set of (agriculture) purchasing power parities which equalise countries’ value of production in local currency to their value of production in a reference currency. By setting a country’s AgPPP as equal to 1 the system provides a unique set of solutions. It has been customary to set the USA’s AgPPP as equal to 1 and to express PPP’s in relation to the US Dollar.	FAO Statistics Division
Prices in local currency	Prices in local currency are nominal producer prices expressed in the local currency prevailing in the current year. Thus currency changes can be observed as breaks in the series.	FAO Statistics Division
Prices in Standard Local Currency (SLC)	Prices in SLC are equal to producer prices in local currency multiplied by currency conversion factors. Currency conversion factors (CCF) are a special kind of exchange rates that convert the new currency of a given country into the old currency of the same country. These series are consistent over time and do not breaks when a currency change occurs.	FAO Statistics Division
Prices in US Dollars (US $)	Prices in US Dollars are equal to producer prices in local currency times the exchange rate of the selected year. The main exchange rates source used is the IMF. Where official and commercial exchange rates differ significantly, the commercial exchange rate may be applied.	FAO Statistics Division
Primary crops	Primary crops are those which come directly from the land and without having undergone any real processing, apart from cleaning. They maintain all the biological qualities they had when they were still on the plants. Certain primary crops can be aggregated, with their actual weight, into totals offering meaningful figures on area, yield, production and utilization; for example, cereals, roots and tubers, nuts, vegetables and fruits. Other primary crops can be aggregated only in terms of one or the other component common to all of them. For example, primary crops of the oil-bearing group can be aggregated in terms of oil or oil cake equivalent. Primary crops are divided into temporary and permanent crops. Temporary crops are those which are both sown and harvested during the same agricultural year, sometimes more than once; permanent crops are sown or planted once and not replanted after each annual harvest.	FAO. 2001. Food balance sheets. A handbook. Rome.
Primary livestock products from live animals	Primary livestock products from live animals include milk, eggs, honey, beeswax and fibres of animal origin.	FAO. 2001. Food balance sheets. A handbook. Rome.
Primary livestock products from slaughtered animals	Primary livestock products come directly from slaughtered animals and include meat,edible offal, slaughtered fats, fresh hides and skins.	FAO. 2001. Food balance sheets. A handbook. Rome.
Primary sampling unit	First level of sub-division of the population, created by selection of a part of the population for further sub-sampling. These may be villages or area blocks which may be sub-divided into segments.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Processed livestock products from live animals	These are derived from primary livestock products from live animals, particularly dairy products, such as butter,cheese,and dried eggs. Production data refer only to primary products while data for all other elements also include processed products derived there from, expressed in primary commodity equivalent.	FAO. 2001. Food balance sheets. A handbook. Rome.
Processed livestock products from slaughtered animals	Derived from the processing of primary livestock products from slaughtered animals and include bacon, ham, sausages, canned meat, lard and tallow. Production data refer only to primary products while data for all other elements also include processed products derived there from, expressed in primary commodity equivalent.	FAO. 2001. Food balance sheets. A handbook. Rome.
Producer price index (PPI)	The PPI measures the average change over time in the selling prices received by domestic producers for their output of a commodity.	FAO Statistics Division
Producer prices	Producer prices are prices received by farmers for primary agricultural products as defined in the SNA 93. The producer's price is the amount receivable by the producer from the purchaser for a unit of a good or service produced as output minus any VAT, or similar deductible tax, invoiced to the purchaser. It excludes any transport charges invoiced separately by the producer. Time series refer to the national average prices of individual commodities comprising all grades, kinds and varieties, received by farmers when they participate in their capacity as sellers of their own products at the farm gate or first-point-of-sale.	FAO Statistics Division
Production	Figures relate to the total domestic production whether inside or outside the agricultural sector, i.e. it includes non-commercial production and production from kitchen gardens. Unless otherwise indicated, production is reported at the farm level for crop and livestock products (i.e. in the case of crops, excluding harvesting losses) and in terms of live weight for fish items (i.e. the actual ex-water weight at the time of the catch). All data shown relate to total meat production from both commercial and farm slaughter. Data are expressed in terms of dressed carcass weight, excluding offal and slaughter fats. Production of beef and buffalo meat includes veal; mutton and goat meat includes meat from lambs and kids; pig meat includes bacon and ham in fresh equivalent. Poultry meat includes meat from all domestic birds and refers, wherever possible, to ready-to-cook weight.	FAO Statistics Division
Production - Livestock primary	Livestock primary products include products from live and slaughtered animals. Products from slaughtered animals include meat, offals, raw fats, fresh hides and skins. Products from live animals include milk, eggs, honey, beeswax and fibres of animal origin. All data shown relate to total meat production from both commercial and farm slaughter. Data are given in terms of dressed carcass weight, i.e. excluding offals and slaughter fats. Production of beef and buffalo meat includes veal; mutton and goat meat includes meat from lambs and kids, respectively; pig meat includes bacon and ham in fresh equivalent. Poultry meat includes meat from all domestic birds and refers, wherever possible, to ready-to-cook weight. Cow milk production relates to total production of whole fresh milk, excluding the milk sucked by young animals but including amounts fed to livestock. The concept of production of buffalo, sheep and goat milk is the same as for cow milk; however, the coverage is probably less adequate. Egg production covers all domestic birds which have contributed to egg production during the year, wherever they lay and the corresponding total production, including eggs intended to be used for hatching but excluding waste on farms.	FAO Statistics Division
Production of derived vegetal products	Processed products of vegetal origin. Their parent products are found in the group 'Primary crops'. Production corresponds to the total output obtained from the processing of the input commodity in question (primary crops) during the calendar year. The quantity includes the output of home processing and of manufacturing industries and traditional processing. Data refer to total net production excluding processing losses, i.e. ex-factory or ex-establishment weight. As with the production of primary crops, it may occur that most of the output is obtained at the end of the calendar year and will be utilized during the following year. Olives picked towards the end of the year are immediately crushed after to avoid spoilage. Olive oil output therefore cannot enter the consumption during the same year. In these cases allocations to and from stocks (in the subsequent years) are made.Production data refer only to primary products while data for all other elements also include processed products derived there from, expressed in primary commodity equivalent.	FAO Statistics Division
Publicity	The means of informing the public of the purpose of the census and ensuring cooperation of the holders during the enumeration process. All kinds of media may be used for the publicity campaign.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Quantity of food and agricultural exports	According to FAO methodology the quantity of food and agricultural exports included in the FAOSTAT database is expressed in terms of weight (tonnes) for all commodities except for live animals which are expressed in units (heads); poultry, rabbits, pigeons and other birds are expressed in thousand units. As a general rule, trade quantity refer to net weight, excluding any sort of container.	FAO Statistics Division
Quantity of food and agricultural imports	According to FAO methodology the quantity of food and agricultural imports included in the FAOSTAT database is expressed in terms of weight (tonnes) for all commodities except for live animals which are expressed in units (heads); poultry, rabbits, pigeons and other birds are expressed in thousand units. As a general rule, trade quantity refer to net weight, excluding any sort of container.	FAO Statistics Division
Questionnaire	The document used by the enumerators for recording the data. Its design is one of the most important operations of the census process.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Raw data	Data on the questionnaire provided by the respondent or measured by the enumerator; such data are not yet reviewed or processed or ready for use. They are normally treated as confidential.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Re-exports	Re-exports refer to foreign goods exported from any part of the economic territory of a country in the same state as previously imported. The term “in the same state” is applicable to foreign goods even if they underwent minor processing which did not change their origin. The scope of re-exports is not restricted to goods flows identified as re-exports in customs records. It includes, for instance, foreign goods which are withdrawn, in the same state, from the free circulation area. Sometimes the latter category of goods is given a special name (e.g. “nationalized” goods) and is included in the outright exportation, not in re-exports. Such practice is not recommended however, since it does not correctly reflect the structure of a compiling country's total exports. Foreign goods which enter a country for temporary storage (e.g. in customs warehouses) and leave the country shortly afterwards are to be excluded from trade statistics (i.e. they are not to be treated as re-exports). In FAOSTAT the export data includes re-export data reported by country.	- UNSD. 2004. International Merchandise Trade Statistics: Compilers Manual. New York. - FAO Statistics Division

Seed	Data include the amounts of the commodity in question set aside for sowing or planting (or generally for reproduction purposes, e.g. sugar cane planted, potatoes for seed, eggs for hatching and fish for bait, whether domestically produced or imported) during the reference period. Account is taken of double or successive sowing or planting whenever it occurs. The data of seed include also, when it is the case, the quantities necessary for sowing or planting the area relating to crops harvested green for fodder or for food.(e.g. green peas, green beans, maize for forage) Data for seed element are stored in tonnes (t). Whenever official data were not available, seed figures have been estimated either as a percentage of supply (e.g. eggs for hatching) or by multiplying a seed rate with the area under the crop of the subsequent year.	FAO. 1986. The ICS users' manual. Interlinked computer strorage and processing system of food and agricultural commodity data. Rome.
Seeders	Seeders are implements for sowing seeds or grain evenly in well-spaced rows at specific depths. Data are expressed in numbers in use in the agricultural sector.	FAO Statistics Division
Self-sufficiency ratio	The self-sufficiency ratio (SSR) is defined as: SSR = production*100/(production + imports – exports). The SSR can be calculated for individual commodities, groups of commodities of similar nutritional values and, after appropriate conversion of the commodity equations, also for the aggregate of all commodities. In the context of food security, the SSR is often taken to indicate the extent to which a country relies on its own production resources, i.e. the higher the ratio the greater the self-sufficiency. While the SSR can be the appropriate tool when assessing the supply situation for individual commodities, a certain degree of caution should be observed when looking at the overall food situation. In the case, however, where a large part of a country's production of one commodity, e.g. other cereals, is exported, the SSR may be very high but the country may still have to rely heavily on imports of food commodities to feed the population. The self-sufficiency rate (as defined above) cannot be the complement to 100 of the import dependency rate, or vice-versa.	FAO. 2001. Food balance sheets. A handbook. Rome.

Shifting cultivation	A land utilization method; a particular piece of land is cultivated for some years and then abandoned for a period required to restore its fertility by natural vegetative growth; it is then cultivated again. The distinguishing feature of shifting cultivation is that neither organic fertilizers nor manure are used to retain soil fertility.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Shifting cultivation	This is a peculiar land utilization method practised generally in remote and not easily accessible areas in certain African countries. A particular piece of land is cultivated for some years and then, when productivity decreases, it becomes more convenient to open up a new piece of land and abandon the exhausted one. Naturally, the crops grown in this sort of itinerant agriculture, are most probably excluded from the regular agricultural surveys.	FAO. 2001. Food balance sheets. A handbook. Rome.
Sink	Any process, activity or mechanism which removes a greenhouse gas, an aerosol, or a precursor of a greenhouse gas from the atmosphere. Notation in the final stages of reporting is the negative (-) sign.

(Eds), IGES, Hayama, Japan.
Special trade	The special trade system is in use when the statistical territory comprises only a particular part of the economic territory, the free circulation area, which is the part within which goods may be disposed of without customs restriction. Consequently, special imports include all goods entering the free circulation area of a compiling country, which means cleared through customs for domestic consumption or for inward processing, including withdrawals from bonded warehouses or industrial free zones. Special exports include all goods leaving the free circulation area of a compiling country, including goods that leave a country after inward processing (wholly or partly produced or manufactured in the country) and goods that leave an industrial free zone.	UNSD. 2004. International Merchandise Trade Statistics: Compilers Manual. New York.
Standard Local Currency (SLC)	The Standard Local Currency of a country is set as the local currency prevailing in the current year.	FAO Statistics Division
Statistical discrepancies	Statistical discrepancies indicate the level of imbalance in the equation and help in detecting the type of mistake in the Supply Utilization Account. In cases of marginal errors and when the figures show a negative balance, the data is suppressed and the account is left blank with the code SD to identify this statistical discrepancy.	FAO Statistics Division
Statistical trade value	Statistical trade value is the sum of the transaction value of goods (or its substitute), and the value of the services performed in delivering the goods to the border of the exporting (or importing) country, and not included in their transaction value.	UNSD. 2004. International Merchandise Trade Statistics: Compilers Manual. New York.
Stock variation	Comprises changes in stocks occurring during the reference period at all levels between the production and the retail levels, i.e. it comprises changes in government stocks, in stocks with manufacturers, importers, exporters, other wholesale and retail merchants, transport and storage enterprises and in stocks on farms. In actual fact, however, the information available often relates only to stocks held by governments and even these are not available for a number of countries and important commodities. In the absence of information on opening and closing stocks changes in stocks are also used for shifting production from the calendar year in which it is harvested to the year in which it is consumed. Net increases in stocks (add to stock) are generally indicated by the sign "-". No sign denotes net decreases (from stock).	FAO Statistics Division
Stratification	Refers to a subdivision of the universe under study into homogeneous areas for sampling purposes, called strata. In each stratum separate samples are taken and separate estimates are made.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.

(Eds), IGES, Hayama, Japan.
Time reference	A point in time or a period of time to which the data collected refer. A point of time may be either a specific date or day of enumeration. A period is used for reporting the activities, such as employment or production, and refers usually to an agricultural year.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Total agricultural exports	Total agricultural exports are expressed in terms of value. They cover all movements out of the country of the commodity in question during the reference period. They include commercial trade, donated quantities and estimates of unrecorded trade.	FAO Statistics Division

It includes areas equipped for full and partial control irrigation, equipped lowland areas, pastures, and areas equipped for spate irrigation. Data are expressed in 1000 hectares.	FAO Statistics Division & AQUASTAT
Total merchandise trade	According to the International Merchandise Trade Statistics Compilers Manual, by UNSD, it is recommended that international merchandise trade statistics record all goods which add to or subtract from the stock of material resources of a country by entering (imports) or leaving (exports) its economic territory. Goods simply being transported through a country (goods in transit) or temporarily admitted or withdrawn (except for goods for inward or outward processing) do not add to or subtract from the stock of material resources of a country and are not included in the international merchandise trade statistics. Customs records are the main source of the data; use of additional sources where customs sources are not available is also recommended. Goods are to be included in statistics at the time when they enter or leave the economic territory of a country; in the case of customs-based data collection systems, the time of recording should be the date of lodgement of the customs declaration. Lists of goods to be included, to be included and recorded separately, and to be excluded are provided. Specific goods are to be excluded from detailed international merchandise trade statistics but recorded separately in order to derive totals of international merchandise trade for national accounts and balance of payments purposes.	UNSD. 2004. International Merchandise Trade Statistics: Compilers Manual. New York.
Total population	The total population usually refers to the present-in-area (de facto) population which includes all persons physically present within the present geographical boundaries of countries at the mid-point of the reference period.

Total unrendered fat	Includes slaughter fats and butchering fats (edible and inedible).	FAO Statistics Division
Track-laying tractors	Track-laying tractors are tractors which travel on steel or rubber or treads. Data are expressed in numbers in use in the agricultural sector.	FAO Statistics Division
Tract	A portion or a sub-division of land which is under single management. It is either a whole holding, an agricultural or non-agricultural part of a holding. Tract is determined, therefore, by definition of a holding and by boundaries of a segment. A holding is composed of one or more tracts.	FAO. 1996. Conducting agricultural censuses and surveys. FAO Statistical Development Series, No. 6. Rome.
Transaction value	The concept of transaction value adopted for the purposes of international merchandise trade statistics is based on the provisions of Article VII of the GATT and on the Agreement on Implementation of Article VII of GATT (the WTO Valuation Agreement). Transaction value is defined as the price actually paid or payable for goods when sold for export to the country of importation. This price is to be calculated as the total payment made or to be made by the buyer to or for the benefit of the seller for the imported goods. Payments can be monetary or in the form of specified goods or services.	UNSD. 2004. International Merchandise Trade Statistics: Compilers Manual. New York.
Transhumance	The seasonal migration of livestock from pastures on plains and lowlands (autumn-winter) to pastures on mountain-sides (in spring and summer) and vice versa is known as transhumance. In areas where transhumance is practised, livestock may be enumerated twice, or may not be enumerated at all if enumerators fail to pay sufficient attention to this livestock-rearing practice.	FAO. 2001. Food balance sheets. A handbook. Rome.
Undernourishment	Undernourishment refers to the condition of people whose dietary energy consumption is continuously below a minimum dietary energy requirement for maintaining a healthy life and carrying out a light physical activity. The number of undernourished people refers to those in this condition.	FAO Statistics Division
Underweight (low weight for age)	Proportion of under-five falling below minus 2 standard deviations (moderate underweight) and minus 3 standard deviations (severe underweight) from the median weight-for-age of reference population recognized by World Health Organization (WHO).	UNICEF
Unit value of agricultural exports	Unit value of the exported commodity is the amount actually paid for one unit (by quantity unit) of the given commodity when sold for exportation to the compiling country or the cost of one unit of the commodity if not sold; the unit value is calculated as the report between the trade value and the trade quantity. In FAOSTAT database the unit value is expressed in US dollars per tonne, US dollars per live animal or US dollars per 1 000 heads in the case of poultry, rabbits, pigeons and other birds.	- UNSD. 2004. International Merchandise Trade Statistics: Compilers Manual. New York. - FAO Statistics Division
Unit value of agricultural imports	Unit value of the imported commodity is the amount actually paid for one unit (by quantity unit) of the given commodity when purchased for importation from the compiling country, or the cost of one unit of the commodity if not purchased; the unit value is calculated as the report between the trade value and the trade quantity. In FAOSTAT database the unit value is expressed in US dollars per tonne, US dollars per live animal or US dollars per 1 000 heads in the case of poultry, rabbits, pigeons and other birds.	- UNSD. 2004. International Merchandise Trade Statistics: Compilers Manual. New York. - FAO Statistics Division
Urban population	Refers to the population residing in urban areas. Usually the urban areas and hence the urban population are defined according to national census definitions which can be roughly divided into three major groups: classification of localities of a certain size as urban; classification of administrative centres of minor civil divisions as urban; and classification of centres of minor civil divisions on a chosen criterion which may include type of local government, number of inhabitants or proportion of population engaged in agriculture, as urban.	UN Demographic Yearbook
Urban poverty headcount (% of population)	Urban poverty rate is the percentage of the urban population living below the national urban poverty line.	World Bank. 2004. World Development Indicators.
Urea	CO(NH₂)₂, is produced from synthetic ammonia and carbon dioxide (CO₂) and contains 46% nitrogen in ammoniac form. Urea may be in granular, prilled or crystalline form.	FAO Statistics Division
Urea and ammonium nitrate solutions	Are produced from concentrated solutions of urea and ammonium nitrate by chemical or blending processes.	FAO Statistics Division
Value of agricultural exports	Value of agricultural exports should be reported in national currency, US dollars or other currency. Export values are mostly reported as FOB. In the FAOSTAT database export values are expressed in thousand US dollars.	- UNSD. 2004. International Merchandise Trade Statistics: Compilers Manual. New York. - FAO Statistics Division
Value of agricultural imports	Value of agricultural imports should be reported in national currency, US dollars or other currency. Import values are mostly reported as CIF. In the FAOSTAT database import values are expressed in thousand US dollars.	- UNSD. 2004. International Merchandise Trade Statistics: Compilers Manual. New York. - FAO Statistics Division
Value of fertilizer exports	Value of fertilizers exported by a country. Data are reported in thousand US dollars. Data received by countries in national currencies are converted by using the average annual exchange rate provided by the International Monetary Fund.	FAO Statistics Division
Value of fertilizer imports	Value of fertilizers imported by a country. Data are reported in thousand US dollars. Data received by countries in national currencies are converted by using the average annual exchange rate provided by the International Monetary Fund.	FAO Statistics Division
Waste	Amount of the commodity in question lost through wastage (waste) during the year at all stages between the level at which production is recorded and the household, i.e. storage and transportation. Losses occurring before and during harvest are excluded. Waste from both edible and inedible parts of the commodity occurring in the household is also excluded. Quantities lost during the transformation of primary commodities into processed products are taken into account in the assessment of respective extraction/conversion rates. Distribution wastes tend to be considerable in countries with hot humid climate, difficult transportation and inadequate storage or processing facilities. This applies to the more perishable foodstuffs, and especially to those which have to be transported or stored for a long time in a tropical climate. Waste is often estimated as a fixed percentage of availability, the latter being defined as production plus imports plus stock withdrawals.	FAO. 1986. The ICS users' manual. Interlinked computer strorage and processing system of food and agricultural commodity data. Rome.
Wasting (low weight for height)	Proportion of under-five falling below minus 2 and minus 3 standard deviations from the median weight-for-height of reference population recognized by World Health Organization (WHO).	UNICEF
