Where rain-fed croplands are worldwide (Landsat, 30 m, 2020)
What it measures. A detailed map of where rain-fed croplands are, split into pure rain-fed cropland and rain-fed cropland mixed with natural vegetation, plus an estimate of how much cropland area there is. Rain-fed means crops watered only by rainfall, not irrigation.
How it's made. Produced from Landsat-8 satellite images spanning 2019-2021 to represent the year 2020, at a fine 30-meter resolution; for now it only covers the lower 48 U.S. states.
How & where you'd use it. Aimed at food- and water-security questions, helping planners and researchers see where farming depends purely on rain versus irrigation.

Official description
The Landsat-Derived Global Rainfed-Cropland Product Level 2 2020 (LGRIP30_L2_RAIN) Version 2 data provides high-resolution, 30 meter (m) cropland data to assist and address food and water security issues of the twenty-first century. As an extension of the Global Food Security-support Analysis Data ([GFSAD](https://www.usgs.gov/centers/western-geographic-science-center/science/global-food-security-support-analysis-data-30-m)) project, LGRIP_L2_RAIN V2 maps agricultural lands by dividing them into rainfed single croplands and rainfed single croplands mixed with natural vegetation, and calculates applicable cropland areas across the globe. LGRIP data are produced using Landsat 8 time-series satellite sensor data for the 2019 through 2021 time period to create a nominal 2020 product. Each LGRIP L2 Rainfed 30 m resolution GeoTIFF file contains a layer that identifies areas of rainfed cropland (cropland areas that are purely dependent on direct precipitation without any artificial watering) divided into single crop and single crop that is mixed with natural vegetation, non-rainfed land (irrigated croplands and areas not classified as cropland), and water bodies over a 10° by 10° area, as well as an accuracy assessment of the product. A low-resolution browse image is also included. Currently, LGRIP30 V2 products only contain data for the conterminous United States (CONUS). LGRIP30 V2 data covering the rest of the globe will be added at a later date.
