Where farmland is rain-fed versus irrigated (30 m)

Landsat-Derived Global Rainfed and Irrigated-Cropland Product 30 m V001
land NASA LPDAAC_ECS Level 3 GeoTIFF
In plain English

What it measures. A detailed global map that classifies farmland into rain-fed cropland (relying only on rainfall) versus irrigated cropland, alongside non-cropland and water bodies, at 30-meter resolution. It also reports irrigated and rain-fed area for every country.

How it's made. Produced from time-series imagery from the Landsat 8 satellite covering 2014-2017 to create a representative map for 2015, delivered as GeoTIFF files with an accuracy assessment.

How & where you'd use it. Supports food and water security work by showing where and how much of the world's cropland depends on irrigation versus rain.

Official description

The Landsat-Derived Global Rainfed and Irrigated-Cropland Product (LGRIP) provides high resolution, global 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-and-water-security-support-analysis)) project, LGRIP maps the world’s agricultural lands by dividing them into irrigated and rainfed croplands and calculates irrigated and rainfed areas for every country in the world. LGRIP data are produced using Landsat 8 time-series satellite sensor data for the 2014-2017 time period to create a nominal 2015 product. Each LGRIP 30 meter resolution GeoTIFF file contains a contains a layer that identifies areas of rainfed cropland (cropland areas that are purely dependent on direct precipitation), irrigated cropland (cropland that had at least one irrigation during the crop growing period), non-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 available.
