Dataset | Year(s) | Res. (m/px) | Model Scale | Coverage | Definition of Cropland |
|---|---|---|---|---|---|
DEA Cropland Extent | 2019 | 10 | AEZ | Continent | “A piece of land of minimum 0.01 ha that is sowed/planted and harvestable at least once within the 12 months after the sowing/planting date.”27,49 |
Dynamic World | 2015–2024 | 10 | Global | Global | “Human planted/plotted cereals, grasses, and crops”21 |
Esri LULC | 2017–2022 | 10 | Global | Global | “Human planted/plotted cereals, grasses, and crops not at tree height; examples: corn, wheat, soy, fallow plots of structured land.”23,50 |
ESA WorldCover | 2020–2021 | 10 | Global | Global | “Land covered with annual cropland that is sowed/planted and harvestable at least once within the 12 months after the sowing/planting date. The annual cropland produces an herbaceous cover and is sometimes combined with some tree or woody vegetation. Note that perennial woody crops will be classified as the appropriate tree cover or shrub land cover type. Greenhouses are considered as built-up.”22,43,51 |
ESA CCI Africa | 2016 | 20 | Continent | Continent | |
GFSAD | 2015 | 30 | AEZ | Global | “Cropland that is cultivated and harvested for food, feed, and (or) fiber, one or more times during a 12-month period; Cropland that is left fallow, even when equipped for agriculture; and Cropland that is permanently cropped with plantations (for example, orchards, vineyards, coffee, tea, and rubber).”29,53 |
Nabil et al. | 2016 | 30 | Mixed | Continent | “all agricultural annual standing croplands, cropland fallows, and permanent plantation crops”24,54 |
GLAD | 2003, 2007,2011, 2015, 2019 | 30 | 1° × 1° | Global | “[…] land used for annual and perennial herbaceous crops for human consumption, forage (including hay) and biofuel. Perennial woody crops, permanent pastures and shifting cultivation are excluded from the definition.”30,55 |
Copernicus Land Cover | 2015–2019 | 100 | Biome | Global | “Cultivated and managed vegetation/agriculture. Lands covered with temporary crops followed by harvest and a bare soil period (e.g., single and multiple cropping systems). Note that perennial woody crops will be classified as the appropriate forest or shrub land cover type.”31,56 |
ESA GlobCover | 2005, 2009 | 300 | Strata | Global | “Post-flooding or irrigated croplands,” “rainfed croplands,” “Mosaic Cropland (50–70%)/Vegetation (grassland, shrubland, forest) (20–50%),” and “Mosaic Vegetation (grassland, shrubland, forest) (50–70%)/Cropland (20–50%)”32,57 |
ASAP Crop Mask | 2017 | 1000 | Mixed | Global | “arable land and permanent crops…independently of their life forms (e.g., tree forms), production systems (i.e., both rainfed and irrigated), and density of cover”11,13,58 |
