Where farmland is irrigated worldwide (30 m)
What it measures. A high-resolution (30-meter) map showing which farmland is irrigated versus rain-fed, and whether irrigated fields grow one crop, two crops, or continuous crops per year. It also marks water bodies.
How it's made. Produced from time-series Landsat 8 imagery spanning 2019-2021 to represent the year 2020, with the data delivered as map tiles covering 10-degree areas.
How & where you'd use it. Supports food and water security work by showing where and how intensively land is irrigated. Note: this version currently covers only the continental United States, with the rest of the world to be added later.

Official description
The Landsat-Derived Global Irrigated-Cropland Product Level 2 2020 (LGRIP30_L2_IRRI) 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_IRRI V2 maps agricultural lands by dividing them into irrigated single crop, double crop, and continuous croplands, 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 Irrigated 30 m resolution GeoTIFF file contains a layer that identifies areas of irrigated cropland (cropland that had at least one irrigation during the crop growing period) divided into single, double, and continuous crop classifications, non-irrigated land (rainfed cropland 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.
