LGRIP: Global Irrigated and Rainfed Cropland Map at 30m

Landsat 8 time-series data from 2014-2017 underpins this global map of agricultural land, distinguishing irrigated and rainfed cropland at a 30-meter resolution. The product calculates national-level areas for both irrigation types to support analysis of food and water security. Each 10° by 10° tile includes a classification layer and an accuracy assessment.

Use Cases

• Assessing national water demand for agriculture based on irrigated cropland area.
• Modeling climate change impacts on rainfed agricultural productivity.
• Monitoring changes in irrigation infrastructure and practices over time.
• Validating and improving global hydrological and crop yield models.

Strengths

• Provides a high-resolution (30-meter) global classification of cropland.
• Includes an accuracy assessment layer for each 10° by 10° data tile.
• Derived from a consistent time-series of Landsat 8 satellite data (2014-2017).

Limitations

• Metadata conflicts exist: the 'last updated' date differs significantly between platforms (2017 vs. 2026).
• The dataset represents a nominal year (2015), which may not capture interannual variability.
• Specific column names and detailed file-level metadata are not provided in the sources.
