Arable land (in hectares) includes land defined by the FAO as land under temporary crops (double-cropped areas are counted once), temporary meadows for mowing or for pasture, land under market or kitchen gardens, and land temporarily fallow. Land abandoned as a result of shifting cultivation is excluded.

Average production of cereals (1999-2001). Average Production of Cereals refers to the amount of cereals produced in a given country or region each year. Data are reported in thousand metric tons. Cereals include wheat, barley, maize, rye, oats, millet, s
Crop production index shows agricultural production for each year relative to the base period 1999-2001. It includes all crops except fodder crops. Regional and income group aggregates for the FAO's production indexes are calculated from the underlying values in international dollars, normalized to the base period 1999-2001.
Average fertilizer use (kg per ha of cropland 2000). Fertilizer use, kilograms per hectare, is calculated by WRI by dividing the total fertilizer consumption, measured in kilograms of plant nutrient, by the total hectares of arable and permanent cropland. The measure of fertilizer consumption is an aggregate of nitrogenous, phosphate and potash fertilizers. The Food and Agriculture Organization of the United Nations (FAO) collects data on fertilizer use through surveys distributed to participating governments. In addition, the Ad Hoc Working Party on Fertilizer Statistics works to improve geographic coverage of the data. Hectares of arable and permanent cropland are determined through a variety of means, including self-reporting from governments and FAO estimation methods.
Food production index covers food crops that are considered edible and that contain nutrients. Coffee and tea are excluded because, although edible, they have no nutritive value.
Agricultural labor as a percent of total labor force. Agricultural labor as a percentage of the total labor force is calculated by WRI by dividing the number of agricultural workers by the total number of workers in the labor force. Agricultural labor for
Tractors per 1000 Hectares of Cropland is calculated by WRI by dividing the number of tractors in use by the total hectares of arable and permanent cropland. Data for agricultural machinery are reported by country governments through surveys. Individual countries have different methods of data collection.
Annual growth rate for agricultural value added based on constant local currency. Aggregates are based on constant 2000 U.S. dollars. Agriculture corresponds to ISIC divisions 1-5 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.
