The Crop Harvested Area and Production data set was created by EarthStat, the University of Minnesota's Institute on the Environment (UMN IonE) and the Land Use and Global Environment Lab at the University of British Columbia (LUGE Lab at UBC). It shows the harvested area, yield and production amount of 175 crops in 206 countries for the year 2000 (average of census data between 1997 and 2003). Harvested area represents the fractional proportion of hectares harvested per gridcell. Production is calculated by multiplying harvested area in hectares and crop yield in tons per hectare. The data were collected from agricultural census and survey information on the areas and yields of 175 crops from the smallest political units reasonably obtainable for 206 countries. Data availability varies for different crops within each country, with most countries having subnational statistics for some crops but national statistics for others. The largest single source of subnational data is Agro-MAPS, a joint project between the Food and Agriculture Organization of the United Nations, the International Food Policy Research Institute and the Center for Sustainability and the Global Environment. Croplands cover about 15 million km² of the planet and provide the bulk of the food and fiber essential to human well-being. Most global land cover data sets from satellites group croplands into just a few categories, thereby excluding information critical for answering key questions on subjects ranging from biodiversity conservation to food security to biogeochemical cycling. Information about agricultural land use practices like crop selection, yield and fertilizer use is even more limited. These EarthStat data present land use data sets created by combining national, state and county-level census statistics with a recently updated global data set of croplands on a 5 minute by 5 minute (~10 km x 10 km) latitude/longitude grid. Resource Watch shows only a subset of the data set. For access to the full data set and additional information, see the Learn More link.
Global Harvested Area and Yield for 175 Crops
These data sets are not intended to be interpreted at the individual grid cell level. The best way to use these maps is to compare counties, states, regions, countries, or continents. Due to the nature of agricultural statistics, the major crop data are more reliable than the data for minor crops. A grid cell may exceed 1.0 or 100% due to multiple harvests per year.
